Turkish involvement in the Syrian Civil War

Turkey and Syria's government

Numerous incidents along the Syrian–Turkish border have taken place during the Syrian Civil War, straining the relations between the countries and resulting in dozens of civilians and military personnel killed.

Following Syria's downing of a Turkish jet in 2012, Turkish Prime Minister Recep Tayyip Erdoğan changed the military's rules of engagement so that any Syrian element approaching the border would be deemed a threat and be treated as a military target. Turkey has bolstered its defenses and deployed additional troops on its border with Syria in mid to late September 2013, with convoys of military vehicles ferrying equipment and personnel and additional short range air defenses set up.

2011 incidents

During the 5 December 2011, about 35 armed fighters tried to cross the border of Syria from Turkey, but were engaged by the Syrian border forces who were able to repel them back to Turkey. Once they were back on Turkish soil, the Turkish army allegedly picked them up in trucks and took care of the injured fighters. A further attempt happened during the night of 12 December, when 15 infiltrators tried again to cross the border. They were unsuccessful and two of them were killed by Syrian border patrols.

2012 incidents

On 22 June 2012, Syrian air defenses shot down a Turkish F-4 Phantom fighter jet, and both pilots were killed. The incident significantly raised tensions between the two countries. Syria stated that it had shot the fighter down using anti-aircraft artillery near the village of Om al-Tuyour, while it was flying over Syrian territorial waters one kilometer away from land. Turkey's foreign minister stated the jet was shot down in international airspace after accidentally entering Syrian airspace, while it was on a training flight to test Turkey's radar capabilities. Turkish Prime Minister Recep Tayyip Erdoğan vowed retaliation, saying: "The rules of engagement of the Turkish Armed Forces have changed ... Turkey will support Syrian people in every way until they get rid of the bloody dictator and his gang." Ankara acknowledged that the jet had flown over Syria for a short time, but they said such temporary overflights were common, had not led to an attack before, and alleged that Syrian helicopters had violated Turkish airspace five times without being attacked and that a second, search-and-rescue jet had been fired at. Assad later expressed regret over the incident. In August 2012, reports appeared in some Turkish newspapers claiming that the Turkish General Staff had deliberately misinformed the Turkish government about the fighter's location when it was shot down. The reports said that a NATO command post at Izmir and a British base in Cyprus had confirmed that the fighter was shot down inside Syrian waters and that radar intelligence from U.S. forces had disproved any "accidentally entered Syrian waters" flightpath error. The General Staff denied the claims.

Tensions were further raised later when Syrian Arab Army mortar rounds began landing in Turkish territory. On 3 October, a Syrian mortar shell hit the Turkish town of Akçakale, killing 5 civilians. Turkey responded by shelling Syrian army positions along the border. Throughout October, Syrian mortar shells repeatedly landed in Turkish territory, and the Turkish military launched retaliatory artillery and mortar strikes, firing into Syria a total of 87 times. These attacks reportedly killed 12 Syrian soldiers and destroyed several tanks.

2013 incidents

In the early hours of 14 January 2013, a shell fired by unknown Syrian forces landed in an olive grove near the border village of Akçabağlar, causing no casualties. On January 30, Syrian El Muhaberat agents tried to cross the border between Turkey and Syria but were turned back under fire by Turkish forces.

On 11 February 2013, a bomb exploded at the Turkısh-Syrian border crossing in Cilvegözü, killing 14. According to BBC, the deadly attack killed 17 people and injured 30 more.

On April 30, 2013, according to Syrian opposition activists, the Syrian air force raided the headquarters of a rebel camp on Syrian-Turkish border, killing 5. Activists told Hurriyet Daily News that the air attack was made on headquarters of a Salafist group Ahrar al-Sham. A Turkish aid worker said the air strike also hit a warehouse on the Syrian side of the border used by aid groups. Another Syrian activist at Bab al-Hawa said people waiting to cross the Syrian-Turkish border were among those hit. He added that at least 15 wounded were taken to hospital near the crossing on the Syrian side and among the dead were a one-and-a-half-year-old child and two teenage girls. Some Syrian activists said some of the casualties were suffering breathing difficulties but said they did not know what type of munitions had been used in the attack. "We cannot confirm that there were any chemical weapons involved," Reyhanli mayor Huseyin Sanverdi told Reuters.

On 2 May 2013, fighting occurred between Syrian anti-government insurgents and Turkish border guards at the Akçakale border crossing. One Turkish border guard was killed in the engagement, reportedly the first armed clashes between Turkish government agents and anti-Assad militants.

On September 16, 2013, Turkish jets shot down a Syrian helicopter on the Syrian-Turkish border. According to Turkish official statement, Turkish warplanes made the intercept after a Syrian Mi-17 helicopter had crossed into Turkish airspace and the government warned it had taken all necessary measures to defend itself against any further such violations. Syrian army acknowledged the helicopter had strayed into Turkish airspace for a short time, while monitoring "terrorists" moving across the border into Syria, but said it was an accident and that the aircraft was on its way back when it was shot down.

The helicopter pilot was beheaded after the crash by Syrian rebels

2014 incidents

On 23 March 2014, Turkish fighter jets shot down a Syrian MiG-23. The Syrian Arab Republic claims that its aircraft was in Syrian airspace on a mission to attack rebel held areas in the city of Latakia when it was shot down by Turkey in an act of "blatant aggression." The Syrian pilot successfully ejected from the aircraft as the aircraft was being shot down. Turkish Prime Minister Erdoğan stated that Turkish F-16s shot down the aircraft for violating Turkish airspace and said that the Turkish "response will be heavy if you violate our airspace."

2015 incidents

In the night of 21–22 February 2015, a convoy of 572 Turkish troops in 39 tanks and 57 armoured vehicles entered Syria through Kobanî to evacuate the 38-man Turkish military garrison guarding the Suleyman Shah tomb and move the remains of Suleyman Shah to a different site because of a rumored attack threat of ISIL. The Turkish military did not seek permission from Syria to carry out the mission, the Syrian Foreign Ministry condemned the move, saying that Turkey "committed an act of flagrant aggression on Syrian land."

On 16 May 2015, a Turkish Air Force F-16 shot down an Iranian made Mohajer 4 UAV that had violated Turkish airspace over Hatay province entering 11 km into Turkish airspace. Initial claims by the Turkish government mentioned an intruding helicopter was shot down, but later it was admitted that the downed aircraft was an UAV as claimed by the Syrian side.

In May, there was a public scandal over video footage released by the newspaper Cumhuriyet purporting to show Turkish intelligence shipping arms to Syrian Islamist rebels. The editor-in-chief and more than thirty officers involved in the search and the attempted search of another truck of weapons some time earlier now face charges for breaking counter-terrorism laws, attempting to overthrow the government and military espionage.

2016 incidents

On 1 February Syria accused the Turkish military of shelling a location in the country’s northern Latakia province. Because of the shelling civilians had been injured. Syrian government condemned the attack.

Also, the Russian Defense Ministry presented a video which claims that shows Turkish military shelling Syrian territory using heavy artillery positioned close to the border. According to Syria’s General Staff, Syrian opposition groups have also provided video evidence of the Turkish military shelling Syrian territory.

On 13 February 2016, Turkey began heavy artillery bombing of Kurds in North Aleppo and at Azaz as they advanced against opposition groups. The US urged Turkey to stop the shelling of the Kurds and focus on fighting the group Islamic State (IS), however, Turkey defied the US and French calls and continued the shelling the next day too. Also, in a telephone call with German Chancellor Angela Merkel, Turkish Prime Minister Ahmet Davutoglu said Turkey will continue to strike back at Kurdish fighters in Syria. Kurdish officials said that at least three YPG fighters have died since the shelling started on Saturday.

Syria called the Turkish strikes a violation of its territory, and urged UN Security Council action to "put an end to the crimes of the Turkish regime". It also accused Ankara of allowing some 100 gunmen to enter Syria, also, the Syrian Observatory for Human Rights said some 350 Islamist fighters had been allowed to travel through Turkish territory on Saturday 14 February 2016 to reinforce Islamist rebels in Azaz and Tal Rifaat.

Turkish artillery also targeted Syrian forces on both days.

The Syrian government has accused Turkey, Qatar and Saudi Arabia of being behind a wave of bombings in the coastal cities of Tartous and Jableh. At least five suicide bombers and two devices planted in cars killed nearly 150 people and wounded at least 200. Islamic State claimed responsibility for the attacks. The attacks were the first of their kind in Tartous and in Jableh. This part of Syria had escaped the worst of the civil war till these attacks. These cities were government-controlled territory that hosted Russian military bases. Russia had a naval base in Tartous and an air base near Jableh.

Turkey and Rojava

Turkey has received the co-chair of Rojava's leading Democratic Union Party (PYD), Salih Muslim, for talks in 2013 and in 2014, even entertaining the idea of opening a Rojava representation office in Ankara "if it's suitable with Ankara's policies.". Nonwithstanding, Turkey is persistently hostile, because it feels threatened by Rojava's emergence encouraging activism for autonomy among Kurds in Turkey and the Kurdish–Turkish conflict, and in this context in particular Rojava's leading Democratic Union Party (PYD) and the People's Protection Units (YPG) militia being members of the Kurdistan Communities Union (KCK) network of organisations, which also includes both political and militant assertively Kurdish organizations in Turkey itself, including the Kurdistan Workers' Party (PKK). Turkey's policy towards Rojava is based on an economic blockade, persistent attempts of international isolation, opposition to the cooperation of the international Anti-ISIL-coalition with Rojava militias, and support of Islamist Syrian Civil War parties hostile towards Rojava, in past times even including ISIL. Turkey has on several occasions also been militarily attacking Rojava territory and defence forces. The latter has resulted in some of the most clearcut instances of international solidarity with Rojava.

In the perception of much of the Turkish public, the Rojava federal project as well as U.S. support against ISIL are elements of a wider conspiracy scheme by a "mastermind" with the aim to weaken or even dismember Turkey, in order to prevent its imminent rise as a global power. Opposition leader Selahattin Demirtas has argued for Turkey and other countries to recognize Rojava and work with it as a partner.

From fall 2014: Kobanî in focus

With the Turkish government thinking that a declaration was enough, and with only a minimum of western airstrikes helping the defenders of Kobanî, ISIL troops edged closer to the city, eventually entering it from the south and east. Feeling betrayed by the Turkish government and hearing that Prime Minister Ahmet Davutoğlu's previous vow not to let Kobanî fall was in fact a lie, refugees on the border and citizens in the cities of Istanbul, Ankara, Antakya, Antalya, Eskişehir, Denizli, Kocaeli, Diyarbakır, Siirt, Batman, and elsewhere began to protest. Turkish police responded with tear gas and water cannons, and live fire in the southern province of Adana, killing protestors.

By 7 October, ISIL militants and Kurdish defenders were fighting in the streets of Kobanî, with many dead and scores wounded on both sides. As the battle for Kobanî continued to rage, rioting continued in Turkey, and almost 40 people were killed in street clashes by mid-October. In late October, ISIL began shelling the border post near Kobanî. On 11 October, Turkish President Erdogan denounced the protests, claiming that they were attacking Turkey's "peace, stability, and environment of trust." He stated that the government was already caring for 200,000 Kurdish refugees from the Kobanî area and asked, "What does Kobanî have to do with Turkey?" By mid-October, fighting had also renewed between Turkish military forces and Kurdistan Workers' Party (PKK) elements in southeastern Turkey.

On 29 November 2014, ISIL fighters began attacking YPG fighters in Kobanî from Turkish territory. Kurdish sources in Kobane said that on November 29 ISIL fighters attacked Kobane from Turkish territory, and that the assault began with a vehicle driven by a suicide bomber coming from Turkish territory. During the attack, a group of ISIL fighters were seen atop granary silos on the Turkish side of the border. According to the German news outlet 'Der Spiegel', ISIL fighters also attacked YPG positions near the border gate from Turkish soil. According to the SOHR, YPG fighters crossed the Turkish border and attacked ISIL positions on Turkish soil, before pulling back to Syria. Soon afterwards, the Turkish Army regained control of the border crossing and silos area.

On 25 June 2015, fighters from ISIL launched an attack against Kobanî, detonating three car bombs. The ISIL fighters were reported to have disguised themselves as Kurdish security forces, before entering the town and shooting civilians with assault rifles and RPGs. Over 164 people were killed and 200 injured. Kurdish forces and the Syrian government claimed the vehicles had entered the city from across the border, an action denied by Turkey. ISIS also committed a massacre in the village of Barkh Butan, about 20 kilometres south of Kobanî, executing at least 23 Syrian Kurds, among them women and children.

From summer 2015: Rojava expands, Turkey becomes openly hostile

On 24 and 25 October 2015, Kurds accused the Turkish military of opening fire at its forces in Tal Abyad after the majority Arab town was included into Kobanî Canton. The Turkish Prime Minister Ahmet Davutoglu confirmed it, saying "we hit it twice,". There were no casualties in the shooting and the Kurdish forces didn't return fire. On October 25, Turkish forces also attacked the village of Buban. During the attack two civilians wounded.

On 15 February 2016, Turkey hit again Kurdish forces in Syria. A Turkish Foreign Ministry spokesman said the strikes came after a border security outpost in the Hatay area was attacked. In addition, the Syrian Observatory for Human Rights said that Turkish troops were shelling the road to the west of the town of Tal Rifaat and also the region to the west of the Syrian border town of Azaz, but failed to stop the advance of the Kurdish forces. On 16 February 2016, Turkish forces continued to shell the positions of Syrian Kurds in northern Syria for the fourth day. Turkish military said that it was retaliating to fire coming from the region. On 17 February 2016, in Ankara, a car bombing attack happened at night. The attack targeted a convoy of military vehicles. Turkish Prime Minister Ahmet Davutoglu and President Erdogan blamed a Syrian Kurdish militia fighter working with Kurdish militants inside Turkey for a suicide car bombing, and vowed retaliation in both Syria and Iraq. However the Kurdistan Freedom Falcons (TAK) took responsibility for the attack and said they targeted security forces.

On February 22, 2016, U.S.-Russia joint cease-fire deal announced to take effect in Syria on Feb. 27, but the “cessation of hostilities” does not include ISIL and the al-Nusra Front, the main jihadist factions. On Feb. 24, Turkish president, Erdoğan, during a speech said that “The PYD and the YPG need to be out of the scope of the cease-fire, just like Daesh (ISIL) is,”. Turkish president Recep Tayyip Erdogan said that Turkey would continue shelling Kurdish militants across the border in Syria, despite calls from Washington and other Western capitals to halt the attacks. On 19 February Turkish artillery units shelled again PYD targets in northern Syria. Opposition groups reported that over the previous few days they had brought over 2,000 reinforcements with heavy equipment from the Idlib area, through Turkey assisted by Turkish forces, to fight against Kurdish militias north of Aleppo and to support rebels in Azaz. Pentagon Press Secretary Peter Cook said that Turkey’s shelling of YPG forces in northern Syria would be an “ongoing topic of conversation” between USA and Turkey.

On 4 March 2016, the YPG militia said that Turkey′s tanks had fired dozens of shells at its positions in the area of Afrin in northwest Syria. Russia’s Defense Ministry reported that Turkey continues to shell Kurdish forces in Syria, hampering their operations against Al-Nusra, and at the same time funneling supplies to the militant-controlled areas at the border. Jihadists and Turkish trucks supplying them continued to freely cross the Turkish-Syrian border. On 6 March, jihadists shelled Turkish areas from Syrian territory in an attempt to provoke a response that could lead to Ankara sending troops into the neighboring country. On 8 March, Mortar shells fired from Syria in Turkey and killed 2 civilians, the Turkish military returned fire into Syria. According to Prime Minister Ahmet Davutoglu, Islamic State militants were responsible for the attack.

From spring 2016: Manbij and international solidarity with Rojava

In December 2015, the Syrian Democratic Forces (SDF), the newly founded umbrella for Rojava-affiliated militias, captured the Tishrin Dam and crossed the Euphrates, capturing the town of Tishrin and other nearby areas from ISIL, paving the way for a future offensive toward Manbij. In April 2016, factions of the SDF formed the Manbij Military Council. The U.S. asked for Turkey's support for the Manbij offensive, but Turkey had two demands that were rejected, namely that the forces in the offensive should leave the secular SDF umbrella, and that the U.S. should increase its airstrikes for jihadist groups Turkey supports. When the offensive started, the Washington Post reported it under the headline of "Ignoring Turkey, U.S. backs Kurds in drive against ISIS in Syria".

During the late summer 2016 Turkish military intervention in the Syrian Civil War in Shahba region, U.S. Special Operations Forces embedded with SDF forces, to successfully deter Turkey and Turkish-backed jihadi rebels from attacking SDF forces south of the Sajur river. Further, the United States Department of Defense confirmed that U.S. Special Operation Forces were flying U.S. flags in the town of Tell Abyad in Kobanî Canton to deter Turkish harassment shelling or attacks against SDF forces there.

Allegations of Turkish cooperation with and support for ISIL

Ever since the formal founding of ISIL from its Islamist predecessor groups in June 2014, Turkey has faced numerous allegations of collaboration with and support for ISIL in international media. Several of the allegations have focused on Turkish businessman and politician Berat Albayrak, who has faced calls for his prosecution in the United States.

Turkey has, despite national and international criticism, largely refused to directly engage militants of the Islamic State of Iraq and the Levant (ISIL), despite continued threats from ISIL to pursue more operations on Turkish soil. The Turkish response to the ISIL-led Siege of Kobanî as well as a series of terrorist attacks on Turkish soil allegedly linked to ISIL perpetrators, was largely subdued apart from a series of incidents on the Turkish–Syrian border. On 23 July 2014 one Turkish sergeant was killed by fire from ISIL forces in Syria, and four Turkish tanks returned fire into ISIL held territory in Syria. The following day ISIL and Turkish soldiers actively engaged in the Turkish border town of Kilis, marking a dangerous new escalation in the ties between Turkey and ISIL. Turkish F-16 Fighting Falcons struck ISIL targets across the border from Kilis Province with smart bombs, the Turkish government announced.

The Turkish government claimed that this was to prevent an attempted invasion by ISIL troops.

On August 25, 2015 Turkish newspaper Bugün ran a front-page story showing alleged transfer of weapon and explosives from Turkey to ISIL through Akcakale border post. A couple of days later offices of Koza İpek Media Group, the owner of the newspaper, were raided by Turkish police.

In late November 2015, Turkey started tougher controls to stop ISIL militants crossing on a 60-mile stretch of the border with Syria where ISIL had control of the Syrian side. The crossing was used for smuggling and for arms transfers. This followed Russian President Putin directly accusing Turkey of aiding ISIL and al-Qaeda, and pressure from the U.S.

From July 2015: Alleged ISIL terror attacks in Turkey

On 7 July 2015, reports surfaced that Turkish security forces seized a truck bound for Syria loaded with 10,000 detonators and explosive primers with total length of 290,000 metres (950,000 feet) in Akcakale, Sanliurfa province, southeastern Turkey. Five people were arrested. The detainees admitted attempts of crossing the border from the village of Aegean into Tal Abyad city in the Al-Raqqah Province.

On 20 July 2015, a cultural center in Suruç was bombed by a 20-year-old male Turkish ISIL member. 32 people were killed in the town of Suruç's municipal culture center in the southeastern province of Şanlıurfa, and at least 100 people were hospitalised.

On 10 October 2015 at 10:04 local time (EEST) in Ankara, the capital city of Turkey, two bombs were detonated outside Ankara Central railway station. With a death toll of 103 civilians, the attack surpassed the 2013 Reyhanlı bombings as the deadliest terror attack in modern Turkish history. Another 500 people were injured.

On 19 March 2016, a suicide bombing took place in Istanbul's Beyoğlu district in front of the district governor's office. The attack occurred at 10:55 (EET) at the intersection of Balo Street with İstiklal Avenue, a central shopping street. The attack caused at least five deaths, including that of the perpetrator. 36 people were injured, including seven whose injuries were severe. Among those injured were twelve foreign tourists. Among those killed, two were of dual Israel-US nationality. On 22 March, the Turkish interior minister said that the bomber had links with ISIL.

On 28 June 2016, ISIL militants attacked Istanbul’s Atatürk Airport. The three suicide bombers opened fire at passengers before blowing themselves up. The attacks left 45 dead and 230 wounded.

From April 2016: Cross-border confrontations

Turkish artillery strikes killed over 54 ISIL militants on April 2016, whilst 5 people were killed and 22 others were wounded by ISIL rocket projectiles hitting the border province of Kilis.

The Turkish Foreign Ministry has demanded raising awareness on the Kilis to the U.S. Department of State. Turkey also demanded the deployment of High Mobility Artillery Rocket System (HIMARS) rocket launchers at Turkey’s Syria border. According to Turkey, such moves would push ISIL militants southwards, leaving the border province of Kilis out of battery ranges.

From 3 May 2016 to 6 May rocket fire struck the Turkish city of Kilis from ISIS controlled territory with the Turkish Army responding with fire at every attack.

On 6 May the governor’s office in Kilis released an official statement declared the province a “special security area,” effective for 15 days until 5:00 p.m. on May 20.

Also, in the morning hours, the Turkish military carried out four separate air strikes against ISIL positions in northern Syria, as part of a joint effort and intelligence with the U.S.-led coalition forces. Two Katyusha rockets were fired from ISIL positions in Syria on the southeastern province of Kilis following the air strikes. Turkish armed forces responded to the attack by shelling ISIL targets with howitzers from the border.

In the evening hours, reconnaissance and surveillance vehicles spotted ISIL positions in the Suran region north of Aleppo and the Baragidah and Kuşacık regions northeast of Tal el Hişn. Army shelled them. A total of 55 ISIL militants were killed in the shellings, while three vehicles and three rocket launchers belonging to the jihadist group were also destroyed.

From 11–15 May a total of 55 ISIL militants were killed by Turkey and U.S.-led coalition in operations targeting positions belonging to the jihadist group in Syria, Turkish security sources have said.

2014 invasion plans

On 27 March 2014 an audio tape recording of high-level Turkish officials discussing Turkey's Syria strategy was released on YouTube. The officials discussed a false flag operation that would lead to an invasion of Syria. YouTube was subsequently blocked in Turkey.

A vote in the Turkish Parliament was scheduled for October 1, 2014 on whether or not to invade Syria as part of the war on ISIL. while preparations for a possible invasion were made. It was later delayed a day.

The de facto "declaration of war" is to take the form of two separate motions—one on Iraq and one on Syria, which would authorize Turkish troops to invade those countries. the opposition said they hadn't been able to read either motion, as the exact text had been delayed.

Deputy Prime Minister Bülent Arınç said that the gist of the resolutions was to extend the current mandate for "hot pursuit" against the PKK and Syrian Army into Syria and Iraq, which was to end the second week in October, and to add ISIS to the list and set up a buffer zone on the Syrian side of the border.

President Recep Tayyip Erdoğan opened the parliamentary session by saying that Turkey would fight against so called Islamic State and other "terrorist" groups in the region but it would stick to its aim of seeing Bashar al-Assad removed from power.

After two days of heated debate, the motion passed 298-98,

2015 invasion plans

With the governing party losing its majority in the Turkish general election on 7 June 2015, rumors began to circulate that President Erdoğan would order an invasion of Syria to prevent the creation of a Kurdish state straddling northern Syria and Iraq.

On June 26, Erdogan said he would "never allow the establishment of a Kurdish state in northern Syria". By the end of June, a number of Turkish newspapers reported that Ankara was considering a ground operation to establish a buffer zone in Northern Syria to prevent Syrian Kurds from declaring an independent state, a zone 110 km long and 33 km deep along the Turkish border.

The military demanded legal backing for such a move, and on 29 June 2015, Erdoğan chaired a meeting of the National Security Council to provide just that.

Leaked plans stated that, sometime during the first couple of weeks of July, up to 18 thousand troops would invade Syria via the Jarablus and Aazaz border crossings, areas in the hands of ISIL and the Free Syrian Army, respectively, and set up a buffer zone to which refugees could be repatriated.

Limiting intervention to airstrikes has also been discussed. The idea of going into Syria proved extremely unpopular with most sections of Turkish society, dissuading the government from invading.

2016 military intervention

In the wake of the major military advances that Syrian government forces and Syrian Democratic Forces made against jihadists during the Northern Aleppo offensive (February 2016), Ankara called for a safe zone and "No-fly zone", "free from clashes", in northern Aleppo governorate. The proposal did not garner any real support from Washington or NATO allies who fear it would require an internationally patrolled no-fly zone and potentially put them in direct confrontation with Assad and his allies. Only, German Chancellor Angela Merkel said, that such a "safe zone" would be "helpful in the current situation." Russia with dominance over Syria's skies, come out against the idea and, also, Russian Foreign Minister Sergey Lavrov said: "This is not Merkel's initiative, this is a Turkish initiative." In addition, Russian Deputy Foreign Minister Gennady Gatilov said that any decision to create a no-fly zone over Syria cannot be made without the approval of the government in Damascus as well as the UN Security Council.

On February 2016 Turkey and Saudi Arabia were pressing for ground operations in Syria, hoping for the involvement of the U.S. and the other allies. Hezbollah said Turkey and Saudi Arabia were using the Islamic State group as a "pretext" to launch a ground operation in Syria.

On 22 August 2016, Turkey fired artillery at ISIS in Jarablus, and it also shelled YPG fighters north of Manbij. A spokesperson for the Kurdish-Arab Syrian Democratic Forces (SDF) said: “The Turkish state officially supports Daesh (ISIS) and bombs the positions of the Manbij Military Council and its countryside in the northern axis of the defense positions at Sajur River,” The SDF is dominated by the Kurdish Democratic Union Party (PYD).

On 24 August 2016, the Turkish armed forces, supported by the U.S., began a declared direct military intervention into Syria.

On 24 August 2016, after 2 days of artillery bombardment and airstrikes, the Turkish Land Forces launched an attack on the ISIL-held town of Jarabulus, followed by hundreds of FSA fighters. They backed by planes from the U.S.-led coalition, launched their first co-ordinated offensive into Syria. Turkey′s president Recep Tayyip Erdoğan said on the first day of the operation, called Euphrates Shield, that it was aimed against both the ISIL and People's Protection Units (YPG), a major component of the SDF, allegedly both ″terror groups that threaten our country in northern Syria″. The immediate goal of the invasion was the capture of the Syrian town of Jarabulus from the ISIL, which was accomplished on the first day of the operation. The SDF managed to take the town of Amarinah from the FSA after a brief firefight. It was the first time Turkish warplanes have struck in Syria since November 2015, when Turkey downed the Russian warplane, and the first significant incursion by Turkish special forces since a brief operation to relocate the tomb of Suleyman Shah, in February 2015.

Turkey shelled Syrian Kurdish forces in the region during all the week before the attack, determined not to let them fill the vacuum if ISIS leaves.

Turkey said the operation was an act of self-defence, in response to Isis shelling of Turkish border towns and suicide bombings and attacks targeting Turkish nationals. Also, the Turkish foreign minister, Mevlüt Çavuşoğlu, said that YPG (Kurds) should return east of Syria's Euphrates River. Both Manbij and Jarablus are west of the river.

Syrian Kurdish forces said that the Turkish operation is motivated more by the desire to stop their advance at Jarablus than by anti-IS sentiment.

On 29 November, Recep Tayyip Erdoğan, the President of the Republic of Turkey, said that the Turkish military launched its operations in Syria to end the rule of Syrian President Bashar al-Assad. Days later Erdogan sought to retract his statement; media observers attributed his outburst to frustration due to failure of his government's Syria policies.

Incirlik Air Base

On October 13, 2014 Turkey denied the United States to use Incirlik Air Base for attacking ISIS militants in Syria. The US has been frustrated that its efforts to build an international coalition to tackle Isis forces from the air have been partly hobbled by the difficulty of getting Turkey engaged. Later, on July 23, 2015 after long negotiations with USA, Turkey has agreed to allow U.S. planes to launch air strikes against Islamic State militants. The U.S. officials declined to give details of the agreement with Turkey. On February 25, 2016, Saudi Arabian war planes began arriving at the base as part of an anti-Isis build-up being deployed over Syria. The Saudi deployment added to US, German and British aircraft already using the base.

On April 2 and 3, 2016, the families of U.S. troops and civilian personnel stationed at İncirlik Air Base left the base after an order by the Pentagon and the U.S. State Department to leave several areas of Turkey for their security.

On August 2016, four Danish F-16 fighter jets have entered combat in Syria for the first time, hitting targets in Raqqa. The four jets, which have been stationed at the İncirlik airbase since June 17, 2016, have been flying surveillance and reconnaissance missions over Syria with combat missions limited to Iraq until then.

United States role in Syrian Civil War

In May 2016 Turkish Foreign Minister Mevlut Cavusoglu was very angry because of some photos which showed US special forces in Syria wearing insignia of Kurdish militia (patch of the YPJ), during joint operations against Islamic State (IS). He called the US "two-faced" and said the practice was "unacceptable". Pentagon press secretary Peter Cook said it is common for US soldiers to attempt to blend in with local partners.

According to Turkish Foreign Minister Mevlüt Çavuşoğlu, Turkey has proposed to USA a detailed plan for joint military operation against jihadists inside Syria with the Americans and other allied troops. But U.S. officials denied it and said that Turkey had not offered a detailed plan but only a few basic concepts which involved joint efforts only to support non-Kurdish forces.

Turkey and the Russian Federation

The Turco-Russian confrontation took place between Turkey and, initially, the Syrian government which turned into a military crisis between Turkey and Russia after the November 2015 shoot-down of a Russian Air Force Su-24 by the Turkish Air Force after an alleged airspace violation. Increased Russian military intervention on behalf the Syrian Government and hostile Turkish territorial responses have all contributed to increasing escalation. Aerial confrontations between two nations have grown more common. Turkey accuses Russian Forces of violating Turkish sovereign airspace and war crimes against Syrian Turkmens. The Russian military has accused Turkey of illegal economic ties with ISIS and planning a military intervention in Syria.

On 22 February 2016, U.S. and Russia announced a deal for a truce to take effect in Syria on 27 February, referred to as “cessation of hostilities”. On 24 February, Turkish president, Erdoğan, during a speech said that “The PYD and the YPG need to be out of the scope of the cease-fire, just like Daesh (ISIL) is.”

On February 25, Turkish prime minister Ahmet Davutoğlu said that Turkey would not comply with the truce: "This deal is not binding for us when a party is of threat to Turkey, when Turkey’s security is at stake".

November 2015 Turkish shootdown of Russian Su-24

Turkey and Russia–Syria–Iran–Iraq coalition

On December 2015, Turkey rejected to join the anti-ISIL quartet of Syria, Iran, Iraq and Russia. Turkish President Recep Tayyip Erdoğan said that he rejected it due to the presence of Syria's president Bashar al-Assad.

During an International Syria Support Group (ISSG) meeting in Vienna on May 17, 2016, Turkish Foreign Minister Mevlüt Çavuşoğlu told his Russian counterpart Sergei Lavrov that if Moscow has any evidence that shows Turkey helping the ISIL then he would resign.

Russian General Staff Lt. Gen. Sergey Rudskoy told journalists that Al-Nusra Front is receiving daily arms shipments across the border from Turkey and that Al-Nusra Front remains a major destabilizing factor in Syria. He also added that Al-Nusra Front often attack the Syrian Government forces despite the cease-fire and that the attacks are confirmed by other nations as well.

On 13 March, Russian Foreign Minister Sergey Lavrov said Russia has evidence of Turkey's "creeping expansion" in northern Syria. He accused Turkey of fortifying positions hundreds of metres from the border, inside Syria and also sending its military across the Syrian border for Operation Against Kurds and to prevent Kurdish groups there from consolidating their positions. Turkey denied the Russian claims.

On 18 March, Russia's UN Ambassador Vitaly Churkin sent a letter to the UN Security Council saying that three Turkish humanitarian organizations (NGOs) sent weapons and supplies to extremists in Syria on behalf of Turkey's MIT intelligence agency. The three NGOs were the Besar Foundation, the Iyilikder Foundation and the Foundation for Human Rights and Freedoms (IHH).

Russo-Turkish regularization of diplomatic ties

On 26 June 2016 Turkish President Recep Tayyip Erdoğan writes Russian President Vladimir Putin to offer condolences to the family of the deceased Russian pilot of the Sukhoi Su-24 warplane shot down last November. The Kremlin has insisted on a personal apology for months. A Turkish spokesman says this is a step toward improving bilateral relations between the two countries.

On 1 July 2016, Turkish and Russian foreign ministers said that the two countries will “coordinate” their policies over Syria.

On 14 July 2016, Turkish Prime Minister Binali Yıldırım has said that al-Assad must go before any change in Turkey’s stance regarding Syria. He added that between al-Assad or ISIL, Turkey cannot choose either of them and that the main reason things have come to this point is because of al-Assad.

Refugees

Satellite images confirmed that the first Syrian camps appeared in Turkey in July 2011, shortly after the towns of Deraa, Homs and Hama were besieged. By June 2013, Turkey has accepted 400,000 Syrian refugees, half of whom are spread around a dozen camps placed under the direct authority of the Turkish Government. In 2014, the number swelled over a million, as some 200-300,000 Syrian Kurds streamed into Turkey in September alone, upon the Siege of Kobane.

The population of Syrian refugees in Turkey has 30 percent in 22 government-run camps near the Syrian-Turkish border. The rest do their best to make ends meet in communities across the country.

Turkey has accepted over 2.7 million Syrian refugees since the beginning of the Syrian Civil War. Turkey has accommodated most of its Syrian refugees in tent cities administered by the country's emergency management agency.

Criticism of Turkish support for jihadists, including ISIL, and of targeting Kurds

Turkey has been accused of supporting or colluding with ISIL, especially by Syrian Kurds. Syrian Kurds and the Turkey's main Kurdish party, HDP, accused Turkey of allowing ISIL soldiers to cross its border and attack the Kurdish town of Kobanî. They also claimed that Islamic State snipers were hiding among grain depots on the Turkish side of the border and firing on the town. In addition. the Syrian Observatory for Human Rights said that the vehicle which is used in a car bombing attack at Kobanî had come from Turkey. According to journalist Patrick Cockburn, there is "strong evidence for a degree of collaboration" between the Turkish intelligence services and ISIL, although the "exact nature of the relationship ... remains cloudy". David L. Phillips of Columbia University's Institute for the Study of Human Rights, who compiled a list of allegations and claims accusing Turkey of assisting ISIL, writes that these allegations "range from military cooperation and weapons transfers to logistical support, financial assistance, and the provision of medical services". Several ISIL fighters and commanders have claimed Turkey supports ISIL. A former ISIS member mentioned that the ISIS groups were essentially given free rein by Turkey's army. He said: "ISIS commanders told us to fear nothing at all because there was full cooperation with the Turks,". "ISIS saw the Turkish army as its ally especially when it came to attacking the Kurds in Syria." Within Turkey itself, ISIL is believed to have caused increasing political polarisation between secularists and Islamists. A video taken in October 2014 shows Turkish soldiers fraternising with Isis fighters near Kobane. Turkish security forces dispersed Kurds who had gathered at the Turkish border with Syria to cross into Syria and fight with Kurdish militants against ISIS. Oliver North tweeted a photograph which he claimed that it shows a Turkish soldier talking friendly with an ISIS anti-aircraft unit.

In addition, Kurds accuse Turkey of using the US-led coalition against IS as a cover to attack the Kurdish PKK in both Turkey and Iraq, and now against the YPG in northern Syria. The Kurds say that Turkey 's bombardment of their positions is helping IS to attack Kurdish-held frontline areas in Syria and Iraq. IS militants attacked Syrian Kurdish villages south of Kobane a day after Turkey began shelling the YPG.

Also, authorities in Turkey have confirmed social media reports that an injured ISIL commander is being treated in a Denizli hospital, saying the militant has every right to receive medical care as he is a Turkish citizen.

Turkey has been further criticized for allowing individuals from outside the region to enter its territory and join ISIL in Syria. With many Islamist fighters passing through Turkey to fight in Syria, Turkey has been accused of becoming a transit country for such fighters and has been labeled the "Gateway to Jihad". Turkish border patrol officers are reported to have deliberately overlooked those entering Syria upon the payment of a small bribe. A report by Sky News exposed documents showing that passports of foreign Islamists wanting to join ISIL by crossing into Syria had been stamped by the Turkish government. American website Al-Monitor stated in June 2014 that Turkey, during the Syrian Civil War, by "ignoring its own border security", had allowed its Syrian border to become a "jihadist highway" for ISIL to let thousands of international jihadists, and other supplies, reach Syria. British newspaper The Guardian stated that Turkey late 2014 "for many months did little to stop foreign recruits crossing its border to Isis". An ISIL commander stated that "most of the fighters who joined us in the beginning of the war came via Turkey, and so did our equipment and supplies", adding that ISIL fighters received treatment in Turkish hospitals. After the 2015 attacks at Paris, President Barack Obama administration told the Turkish government to close its borders to ISIS fighters. A USA senior official said in the Wall Street Journal "The game has changed. Enough is enough. The border needs to be sealed,” “This is an international threat, and it’s coming out of Syria and it’s coming through Turkish territory.”.

Turkey has openly supported jihadi groups, such as Ahrar ash-Sham, which espouses much of al-Qaida’s ideology, and Jabhat al-Nusra, which is proscribed as a terror organisation by much of the US and Europe.

Turkey reported that between 1957 and 1998, Turkish forces laid 615,419 antipersonnel mines along the Syrian border “to prevent illegal border crossings,” These mines are killing Syrians stuck on the border or trying to cross near Kobani. Turkey is required under the Mine Ban Treaty, to destroy all antipersonnel mines, but has missed deadlines. Human Rights Watch claims in its report that as of November 18 over 2,000 civilians were still in the Tel Shair corridor section of the mine belt due to the fact that Turkey had been refusing entry for cars or livestock, and the refugees did not want to leave behind their belongings.

Russia told that for a long time has been aware of oil going from Syria under the control of terrorists to Turkey. The money finances terrorist groups. Vladimir Putin said that “IS has big money, hundreds of millions or even billions of dollars, from selling oil. In addition they are protected by the military of an entire nation. One can understand why they are acting so boldly and blatantly. Why they kill people in such atrocious ways. Why they commit terrorist acts across the world, including in the heart of Europe,”. Also, Western intelligence officials said that they can track the ISIS oil shipments as they move across Iraq and into Turkey’s southern border regions. The Obama administration was struggling to cut off the millions of dollars in oil revenue that has made the ISIS, but they were unable to persuade Turkey. In addition, the former Iraqi member of Parliament Mowaffak al-Rubaie has accused Turkey of turning a blind eye to the black market ISIS oil trade. He said that there is “no shadow of a doubt” that the Turkish government knows about the oil smuggling operations. “The merchants, the businessmen [are buying oil] in the black market in Turkey under the noses – under the auspices if you like – of the Turkish intelligence agency and the Turkish security apparatus.” In June 2014, a member of Turkey's parliamentary opposition, Ali Edibogluan, claimed that IS had smuggled $800 million worth of oil into Turkey from Syria and Iraq. Sadik Al Hiseni, the head of the security committee in the city of Diyala in Iraq, says they have arrested several Turkish tankers trying to take ISIS oil out of the province of Salahuddin.

Vladimir Putin, also, accused the Turkish government that it is purposely leading the country toward Islamization. Russian Prime Minister Dmitry Medvedev said “Turkey’s actions are de facto protection of Islamic State,” Medvedev said, calling the group formerly known as ISIS by its new name. “This is no surprise, considering the information we have about direct financial interest of some Turkish officials relating to the supply of oil products refined by plants controlled by ISIS.”

Iraqi Prime Minister Haider al-Abadi said that most of the oil produced in Islamic State-held territory in Iraq and Syria was being smuggled through Turkey. He also mentioned that he sees no evidence that Turkey wants to fight ISIS. In addition he told that Turkey wants to revive the Ottoman Empire.

Sadi Pria, a top Iraqi Kurdish official in Irbil said: "Turkey shamelessly and openly backs IS and al-Qaeda terrorists against Kurdish freedom fighters,".

Israel's defence minister, Moshe Ya'alon, has accused Turkey of buying oil from the ISIS and funds ISIS militants. He, also, said that Turkey had "permitted jihadists to move from Europe to Syria and Iraq and back".

The Director of National Intelligence, James R. Clapper, said that he was not optimistic that Turkey would do more in the fight against the Islamic State. “I think Turkey has other priorities and other interests.” He also cited public opinion polls in Turkey that show Turks do not see the Islamic State as a primary threat.

Vice President of USA, Joe Biden, during a speech at Harvard accused Turkey and the Gulf countries of funding, supplying and supporting ISIL. Donald Trump,the Minister of Defense of Armenia, Seyran Ohanyan, accused Turkey of supporting ISIS.

A senior Jordanian security official accused Turkey of training ISIS fighters. The King of Jordan, Abdullah, said that the Turkish president, Recep Tayyip Erdoğan, “believes in a radical Islamic solution to the problems in the region” and the “fact that terrorists are going to Europe is part of Turkish policy, and Turkey keeps getting a slap on the hand, but they get off the hook”.

Egypt has accused Turkish President Recep Tayyip Erdogan of being a supporter of terrorists who seek to "provoke chaos" in the Middle East. Also, an Egyptian security official said that Turkey is providing direct support to ISIS and that Turkish intelligence is passing satellite imagery and other data to ISIS. Egypt, also, claimed that Turkey provided more than 10,000 passports to ISIS members to facilitate travel of its fighters across the region. Egypt official further charged that Istanbul is serving as the “headquarters” for ISIS planning.

Kemal Kılıçdaroğlu, warned the Turkish government not to provide money and training to terror groups. He said, "It isn't right for armed groups to be trained on Turkish soil. You bring foreign fighters to Turkey, put money in their pockets, guns in their hands, and you ask them to kill Muslims in Syria. We told them to stop helping ISIS." He, also, said after the 2015 Ankara bombings that the Turkish Government is "protecting" the ISIL and that "the police department knows all", “the only reason for not having security measures taken or for not having them [suspects] detained is the absence of an instruction from the political authority to fulfill whatever was required. That’s to say, its [the political authority’s] protection of ISIL. This is not an observation, I’m saying this very openly and clearly,”. At 16 February 2016, Kılıçdaroğlu has repeated accusations that the Turkish government has sent arms to jihadist groups in Syria and built jihadist training camp in Turkey.

Russian anti-drug chief mentioned that ISIS is using Turkey for trafficking heroin to Europe. He, also, believes that ISIS makes about $1 billion from Afghan heroin trade.

Turkey's state intelligence agency, MIT, has been accused that it helped deliver arms to parts of Syria under Islamist rebel control. Turkish journalists who exposed it have charged with spying and “divulging state secrets” from the Turkish court. One of the journalists claimed:"Those who sent the convoy from Turkey knew that the weapons were “heading to end [up] in ISIS hands". Also, Turkish officers, who intercepted some of the intelligence agency’s weapons-filled trucks have faced spying charges. In addition, Turkish newspaper, Cumhuriyet, published a video footage which it said showed security forces discovering weapons parts being sent to Syria on trucks belonging to the MIT state intelligence agency.

Syria's president Bashar al-Assad during an interview at 2015 mentioned that military and logistic support from Turkey was the key factor in ISIL takeover of Idlib (2015 Idlib offensive), he also blamed Turkey for the failure of a humanitarian ceasefire plan in Aleppo. He told that: "The Turks told the factions - the terrorists that they support and they supervise - to refuse to cooperate with de Mistura".

Syria's antiquities chief has accused Turkey of refusing to return looted objects from ancient heritage sites in Syria or to provide information about them. Also, Turkey have been accused that she lets ISIL smuggles Syrian antiquities through her.

In an official letter to UN, the Russian envoy Vitaly Churkin stated that antiquities from Syria and Iraq are exported to Turkey. The main center for the smuggling of cultural heritage items is the Turkish city of Gaziantep, where the stolen goods are sold at illegal auctions. According to the envoy, new smuggling hubs are popping up on the Turkish-Syrian border, with the “bulky goods” being delivered by the Turkish transport companies. Smuggled artifacts then arrive in the Turkish cities of Izmir, Mersin and Antalya, where representatives of international criminal groups produce fake documents on the origin of the antiquities.

According to Gatestone Institute, Norddeutscher Rundfunk (NDR) and Südwestrundfunk (SWR) ISIS was selling women and children in Turkey. Also, Consortium of Public Broadcasters in Germany (ARD) produced a footage documenting the slave trade being conducted by the Islamic State (ISIS) in Turkey.

A US-led raid, at which the ISIS official responsible for oil smuggling Abu Sayyaf was killed, produced evidence that Turkish officials directly dealt with ranking ISIS members. Senior Western official familiar with the captured intelligence told the Observer that “There are hundreds of flash drives and documents that were seized there,”. “They are being analysed at the moment, but the links are already so clear that they could end up having profound policy implications for the relationship between us and Ankara.”

Serena Shim, a journalist of Press TV was killed at a car crash with a heavy vehicle in Turkey in what are claimed, by her employer and her parents, to be suspicious circumstances.

She also claimed that she had received images of ISIL militants crossing the Turkish border into Syria in World Food Organization and other NGOs trucks.

At January 2016, The Guardian obtained documents which show that ISIL ran a sophisticated immigration operation through the Syrian border town of Tell Abyad with Turkey until its defeat by Kurds. The border crossing remained open until Kurdish forces took control of the town (Tell Abyad offensive), at which point Turkey promptly sealed it. David Phillips, an academic at Columbia University and author of two recent research papers into links between Turkey and ISIS, alleges that the country “knows the movements of all persons and can control the flow across the border if it chooses”. He said there was “a steady stream of vehicles, individuals, weapons, financing, oil going back and forth”, adding: “It’s not like people are putting on their hiking boots and crossing over rough terrain. There’s an extensive surface transport network which is highly regulated and controlled ... on both sides of the border.”. Academic researcher Aymenn al-Tamimi, an expert on examining Isis documents, said he had no doubt about the authenticity of the manifests. “The documents ... coincide with other documents illustrating daily bus routes within Islamic State territory. Though private companies provide the actual transportation, the Islamic State bureaucracy is responsible for authorising and overseeing the routes,” he said. A senior Turkish government official, in response to the Guardian’s claims, said that Turkey was doing everything it could to stop the influx of foreign fighters, including cracking down on recruitment and logistic networks such as travel agents mentioned in the documents.
