From 1975 to 1990, groups in competing alliances with neighboring countries fought against each other in the Lebanese Civil War. Infighting and massacres between these groups claimed several thousand victims. Examples: the Syrian-backed Karantina massacre (January 1976) by the Kataeb and its allies against Kurds, Syrians and Palestinians in the predominantly Muslim slum district of Beirut; Damour (January 1976) by the PLO against Christian Maronites, including the family and fiancée of the Lebanese Forces intelligence chief Elie Hobeika; and Tel al-Zaatar (August 1976) by Phalangists and their allies against Palestinian refugees living in a camp administered by UNRWA. The total death toll in Lebanon for the whole civil war period was around 150,000 victims.
The PLO had been attacking Israel from southern Lebanon and Israel had been bombing PLO positions in southern Lebanon since the early 1970s till early 1980s.
The casus belli cited by the Israeli side to declare war, however, was an assassination attempt, on 3 June 1982, made upon Israeli Ambassador to Britain Shlomo Argov. The attempt was the work of the Iraq-based Abu Nidal, possibly with Syrian or Iraqi involvement. Historians and observers such as David Hirst and Benny Morris have commented that the PLO could not be have been involved in the assault, or even approved of it: Abu Nidal's group was, after all, a bitter rival to Arafat's PLO and even murdered some of its members. The PLO also issued a condemnation of the attempted assassination of the Israeli ambassador. Nonetheless Israel used the event as a justification to break the ceasefire with the PLO, and as a casus belli for a full-scale invasion of Lebanon. After the war, Israel presented its actions as a response to terrorism being carried out by the PLO from several fronts, including from the border with Lebanon. However, the aforementioned historians have argued that the PLO was respecting the ceasefire agreement then in force with Israel and keeping the border between the Jewish state and Lebanon more stable than it had been for a period of over a decade. During that ceasefire, which lasted 8 months, UNIFIL — the UN peacekeeping forces in Lebanon — reported that not a single act of provocation against Israel had been launched by the PLO. The Israeli government tried out several justifications to ditch the ceasefire and attack the PLO, at some point even eliciting accusations from the Israeli opposition that "demagogy" from the government threatened to pull Israel into war. All such justifications, before the attempted assassination of the ambassador, had been shot down by its ally, the United States, as insufficient reason to launch a war against the PLO.
On 6 June 1982, Israel invaded Lebanon moving northwards to surround the capital, Beirut. Following an extended siege of the city, the fighting was brought to an end with a U.S.-brokered agreement between the parties on 21 August 1982, which allowed for safe evacuation of the Palestinian fighters from the city under the supervision of Western nations and guaranteed the protection of refugees and the civilian residents of the refugee camps.
On 15 June 1982, 10 days after the start of the invasion, the Israeli Cabinet passed a proposal put forward by the Prime Minister, Menachem Begin, that the IDF should not enter West Beirut but this should be done by Lebanese Forces. Chief of Staff, Rafael Eitan, had already issued orders that the Lebanese predominantly Christian, right-wing militias should not take part in the fighting and the proposal was to counter public complaints that the IDF were suffering casualties whilst their allies were standing by. The subsequent Israeli inquiry estimated the strength of militias in West Beirut, excluding Palestinians, to be around 7,000. They estimated the Phalange to be 5,000 when fully mobilized of whom 2,000 were full-time.
On 23 August 1982, Bachir Gemayel, leader of the right-wing Lebanese Forces, was elected President of Lebanon by the National Assembly. Israel had relied on Gemayel and his forces as a counterbalance to the PLO, and as a result, ties between Israel and Maronite groups, from which hailed many of the supporters of the Lebanese Forces, had grown stronger.
By 1 September, the PLO fighters had been evacuated from Beirut under the supervision of Multinational Force. The evacuation was conditional on the continuation of the presence of the MNF to provide security for the community of Palestinian refugees in Lebanon. Two days later the Israeli Premier Menachem Begin met Gemayel in Nahariya and strongly urged him to sign a peace treaty with Israel. According to some sources, Begin also wanted the continuing presence of the SLA in southern Lebanon (Haddad supported peaceful relations with Israel) in order to control attacks and violence, and action from Gemayel to move on the PLO fighters which Israel believed remained a hidden threat in Lebanon. However, the Phalangists, who were previously united as reliable Israeli allies, were now split because of developing alliances with Syria, which remained militarily hostile to Israel. As such, Gemayel rejected signing a peace treaty with Israel and did not authorize operations to root out the remaining PLO militants.
On 11 September 1982, the international forces that were guaranteeing the safety of Palestinian refugees left Beirut. Then on 14 September, Gemayel was assassinated in a massive explosion which demolished his headquarters. Eventually, the culprit, Habib Tanious Shartouni, a Lebanese Christian, confessed to the crime. He turned out to be a member of the Syrian Social Nationalist Party and an agent of Syrian intelligence. Palestinian and Lebanese Muslim leaders denied any connection to him.
On the evening of 14 September, following the news that Bashir Gemayel had been assassinated, Prime Minister Begin, Minister for Defence Sharon and Chief of Staff Eitan agreed that the Israeli army should invade West Beirut. The public reason given was to be that they were there to prevent chaos. In a separate conversation, at 20:30 that evening, Sharon and Eitan agreed that the IDF should not enter the Palestinian refugee camps but that the Phalange should be used. The only other member of the cabinet who was consulted was Foreign Minister Yitzhak Shamir. Shortly after 6.00 am 15 September, the Israeli army entered West Beirut, This Israeli action breached its agreement with the United States not to occupy West Beirut and was in violation of the ceasefire.
Fawwaz Traboulsi writes that while the massacre was presented as a reaction to the assassination of Bachir, it represented the posthumous achievement of his "radical solution" to Palestinians in Lebanon, who he thought of as "people too many" in the region. Later, the Israeli army’s monthly journal Skira Hodechith wrote that the Lebanese Forces hoped to provoke "the general exodus of the Palestinian population" and aimed to create a new demographic balance in Lebanon favouring the Christians.
On the night of the 14/15 September 1982 the IDF chief of staff Eitan flew to Beirut where he went straight to the Phalangists' headquarters and instructed their leadership to order a general mobilisation of their forces and prepare to take part in the forth-coming Israeli attack on West Beirut. He also ordered them to impose a general curfew on all areas under their control and appoint a liaison officer to be stationed at the IDF forward command post. He told them that the IDF would not enter the refugee camps but that this would be done by the Phalangist forces. The militia leaders responded that the mobilisation would take them 24 hours to organise.
On morning of Wednesday 15 September Israeli Defence Minister, Sharon, who had also travelled to Beirut, held a meeting with Eitan at the IDF's forward command post, on the roof of a five storey building 200 metres southwest of Shatila camp. Also in attendance were Sharon's aide Avi Duda'i, the Director of Military Intelligence -Yehoshua Saguy, a senior Mossad officer, General Amir Drori, General Amos Yaron, an Intelligence officer, the Head of GSS – Avraham Shalom, the Deputy Chief of Staff – General Moshe Levi and other senior officers. It was agreed that the Phalange should go into the camps. According to the Kahan Commission report throughout Wednesday, R.P.G. and light-weapons fire from the Sabra and Shatilla camps was directed at this forward command post, and continued to a lesser degree on Thursday and Friday (16–17.9.82). It also added that by Thursday morning, the fighting had ended and all was 'calm and quiet'.
Following the assassination of Lebanese Christian President Bachir Gemayel, the Phalangists sought revenge. By noon on 15 September, Sabra and Shatila had been surrounded by the IDF, which set up checkpoints at the exits and entrances, and used a number of multi-story buildings as observation posts. Amongst them was the seven-story Kuwaiti embassy which, according to TIME magazine, had "an unobstructed and panoramic view" of Sabra and Shatila. Hours later, IDF tanks began shelling Sabra and Shatila.
The following morning, 16 September, the sixth IDF order relating to the attack on West Beirut was issued. It specified: "The refugee camps are not to be entered. Searching and mopping up the camps will be done by the Phalangists/Lebanese Army".
According to Linda Malone of the Jerusalem Fund, Ariel Sharon and Chief of Staff Rafael Eitan met with Phalangist militia units and invited them to enter Sabra and Shatila, claiming that the PLO was responsible for Gemayel's assassination. The meeting concluded at 15:00 on 16 September.
Chatila had previously been one of the PLO's three main training camps for foreign fighters and the main training camp for European fighters. The Israelis maintained that 2,000 to 3,000 terrorists remained in the camps, but were unwilling to risk the lives of more of their soldiers after the Lebanese army repeatedly refused to "clear them out." No evidence was offered for this claim. There were only a small number of forces sent into the camps and they suffered minimal casualties. Two Phalangists were wounded, one in the leg and another in the hand. Investigations after the massacre found few weapons in the camps. Thomas Friedman, who entered the camps on Saturday, mostly found groups of young men with their hands and feet bound, who had been then lined up and machine-gunned down gang-land style, not typical he thought of the kind of deaths the reported 2,000 terrorists in the camp would have put up with.
An hour later, 1,500 militiamen assembled at Beirut International Airport, then occupied by Israel. Under the command of Elie Hobeika, they began moving towards the area in IDF-supplied jeeps, some bearing weapons provided by Israel, following Israeli guidance on how to enter it. The forces were mostly Phalangist, though there were some men from Saad Haddad's "Free Lebanon forces". According to Ariel Sharon and Elie Hobeika's bodyguard, the Phalangists were given "harsh and clear" warnings about harming civilians. However, it was by then known that the Phalangists presented a special security risk for Palestinians. It was published in the September 1st edition of Bamahane, the IDF newspaper, that a Phalangist told an Israeli official: "[T]he question we are putting to ourselves is — how to begin, by raping or killing?" A US envoy to the Middle East expressed horror after being told of Sharon's plans to send the Phalangists inside the camps, and Israeli officials themselves acknowledged the situation could trigger "relentless slaughter".
The first unit of 150 Phalangists entered Sabra and Shatila at 18:00. A battle ensued that at times Palestinians claim involved lining up Palestinians for execution. During the night, the Israeli forces fired illuminating flares over the area. According to a Dutch nurse, the camp was as bright as "a sports stadium during a football game".
At 19:30, the Israeli Cabinet convened and was informed that the Phalangist commanders had been informed that their men must participate in the operation and fight, and enter the extremity of Sabra, while the IDF would guarantee the success of their operation though not participate in it. The Phalangists were to go in there "with their own methods". After Gemayel's assassination there were two possibilities, either the Phalange would collapse or they would undertake revenge, having killed Druze for that reason earlier that day. With regard to this second possibility, it was noted, 'it will be an eruption the likes of which has never been seen; I can already see in their eyes what they are waiting for.' 'Revenge' was what Bashir Gemayel's brother had called for at the funeral earlier. Levy commented:'the Phalangists are already entering a certain neighborhood – and I know what the meaning of revenge is for them, what kind of slaughter. Then no one will believe we went in to create order there, and we will bear the blame. Therefore, I think that we are liable here to get into a situation in which we will be blamed, and our explanations will not stand up..." The press release that followed reads:
"In the wake of the assassination of the President-elect Bashir Jemayel, the I.D.F. has seized positions in West Beirut in order to forestall the danger of violence, bloodshed and chaos, as some 2,000 terrorists, equipped with modern and heavy weapons, have remained in Beirut, in flagrant violation of the evacuation agreement."
An Israeli intelligence officer present in the forward post, wishing to obtain information about the Phalangists' activities, ordered two distinct actions to find out what was happening. The first failed to turn up anything. The second resulted in a report at 20:00 from the roof, stated that the Phalangists' liaison officer had heard from an operative inside the camp that he held 45 people and asked what he should do with him. The liaison officer told him to more or less "Do the will of God." The Intelligence Officer received this report at approximately 20:00 from the person on the roof who heard the conversation. He did not pass on the report.
At roughly the same or a little earlier at 19:00, Lieutenant Elul testified, that he had overheard a radio conversation between one of the militia men in the camp and his commander Hobeika in which the former asking what he was to do with 50 women and children who had been taken prisoner. Hobeika's reply was: "This is the last time you're going to ask me a question like that; you know exactly what to do." Other Phalangists on the roof started laughing. Amongst the Israelis there was Brigadier General Yaron, Divisional Commander, who asked Lieutenant Elul, his Chef de Bureau, what the laughter was about and Elul translated what Hobeika had said. Yaron then had a five-minute conversation, in English, with Hobeika. What was said is unknown.
The Kahan Commission determined that the evidence pointed to 'two different and separate reports', noting that Yaron maintained that he thought they referred to the same incident, and that it concerned 45 "dead terrorists". At the same time, 20:00, a third report came in from liaison officer G. of the Phalangists who in the presence of numerous Israeli officers, including general Yaron, in the dining room, stated that within 2 hours the Phalangists had killed 300 people, including civilians. he returned sometime later and changed the number from 300 to 120.
At 20:40, General Yaron held a briefing, and after it the Divisional Intelligence Officer stated that it appeared no terrorists were in the Shatila camp, and that the Phalangists were in two minds as to what to do with the women, children and old people they had massed together, either to lead them somewhere else or that they were told, as the liaison officer was overheard saying, to 'do what your heart tells you, because everything comes from God. Yaron interrupted the officer and said he'd checked and that 'they have no problems at all,' and that with regard to the people, 'It will not, will not harm them.' Yaron later testified he had been skeptical of the reports and had in any case told the Phalangists not to harm civilians.
At 23:00 the same evening, a report was sent to the IDF headquarters in East Beirut, reporting the killings of 300 people, including civilians. The report was forwarded to headquarters in Tel Aviv and Jerusalem, and to the office of the Bureau Chief of the director of Military Intelligence, Lt. Col. Hevroni, at 05:30 the following day where it was seen by more than 20 senior Israeli officers. It was then forwarded to his home by 06:15. That same morning an IDF historian copied down a note, which later disappeared, which he had found in the Northern Command situation room in Aley.
"During the night the Phalangists entered the Sabra and Shatilla refugee camps. Even though it was agreed that they would not harm civilians, they 'butchered.' They did not operate in orderly fashion but dispersed. They had casualties, including two killed. They will organize to operate in a more orderly manner – we will see to it that they are moved into the area."
Early on that morning, between 08:00 and 09:00, several IDF soldiers stationed nearby noted killings were being conducted against the camp refugees. A deputy tank commander some 180 metres (200 yd) away, Lieutenant Grabowski, saw two Phalangistists beating two young men, who were then taken back into the camp, after which shots rang out, and the soldiers left. Sometime later, he saw the Phalangists had killed a group of five women and children. When he expressed a desire to make report, the tank crew said they had already heard a communication informing the battalion commander that civilians had been, and that the latter had replied, "We know, it's not to our liking, and don't interfere."
At around 08:00, military correspondent Ze'ev Schiff received a tip-off a source in the General Staff in Tel Aviv that there had been a slaughter in the camps. Checking round for some hours, he got no confirmation other than that there "there's something." At 11:00 he met with Mordechai Tzipori, Minister of Communications and conveyed his information. Unable to reach Military Intelligence by phone, he got in touch with Yitzhak Shamir at 11:19 asking him to check reports of a Phalangist slaughter in the camps. Shamir testified that from his recollection the main thing Tzipori had told him of was that 3/4 IDF soldiers killed, no mention of a massacre or slaughter, as opposed to a "rampage" had been made. He made no check because his impression was that the point of the information was to keep him updated on IDF losses. At a meeting with American diplomats at 12:30 Shamir made no mention of what Tzipori told him, saying he expected that he would hear from Ariel Sharon, the Military Intelligence chief and the American Morris Draper about the situation in West Beirut, At that noontime meeting Sharon insisted that "terrorists" needed "mopping up." Americans pressed for the intervention of the Lebanese National Army, and for an I.D.F. withdrawal immediately. Sharon replied:
"I just don’t understand, what are you looking for? Do you want the terrorists to stay? Are you afraid that somebody will think that you were in collusion with us? Deny it. We denied it,"
adding that nothing would happen except perhaps for a few more terrorists being killed, which would be a benefit to all. Shamir and Sharon finally agreed to a gradual withdrawal, at the end of Rosh Hashana, two days later. Draper then warned them:
"Sure, the I.D.F. is going to stay in West Beirut and they will let the Lebanese go and kill the Palestinians in the camps."
"So, we’ll kill them. They will not be left there. You are not going to save them. You are not going to save these groups of the international terrorism.. . If you don’t want the Lebanese to kill them, we will kill them."
In the afternoon, before 16:00, Lieutenant Grabowski had one of his men ask a Phalangist why they were killing civilians, and was told that pregnant women will give birth to children who will grow up to be terrorists.
At Beirut airport at 16:00 journalist Ron Ben-Yishai heard from several Israeli officers that they had heard that killings had taken place in the camps. At 11:30 he telephoned Ariel Sharon to report on the rumours, and was told by Sharon that he had already heard of the stories from the Chief of Staff. At 16:00 in a meeting with the Phalangist staff, with Mossad present, the Israeli Chief of Staff said he had a "positive impression" of their behavior in the field and from what the Phalangists reported, and asked them to continue 'mopping up the empty camps' until 5.am., whereupon they must desist due to American pressure. According to the Kahan Commission investigation, neither side explicitly mentioned to each other reports or rumours about the way civilians were being treated in the camp. Between 18:00 and 20:00, Israeli diplomats in Beirut received complaints from U.S. representatives concerning 18:00–20:00, Foreign Ministry personnel in Beirut and in Israel began receiving various reports from U.S. representatives that the Phalangists had been observed in the camps and that their presence was likely to cause problems. On returning to Israel the Chief of Staff spoke to Ariel Sharon between 20:00 and 21:00, and according to Sharon, informed him that the "Lebanese had gone too far", and that "the Christians had harmed the civilian population more than was expected." This, he testified, was the first he had ever heard of Phalangist irregularities in the camps. The Chief of Staff denied they had discussed any killings "beyond what had been expected".
Later in the afternoon, a meeting was held between the Israeli Chief of Staff and the Phalangist staff.
On the morning of Friday, 17 September, the Israeli Army surrounding Sabra and Shatila ordered the Phalange to halt their operation, concerned about reports of a massacre.
On 17 September, while Sabra and Shatila still were sealed off, a few independent observers managed to enter. Among them were a Norwegian journalist and diplomat Gunnar Flakstad, who observed Phalangists during their cleanup operations, removing dead bodies from destroyed houses in the Shatila camp.
Many of the bodies found had been severely mutilated. Many boys had been castrated, some were scalped, and some had the Christian cross carved into their bodies.
Janet Lee Stevens, an American journalist, later wrote to her husband, Dr. Franklin Lamb, "I saw dead women in their houses with their skirts up to their waists and their legs spread apart; dozens of young men shot after being lined up against an alley wall; children with their throats slit, a pregnant woman with her stomach chopped open, her eyes still wide open, her blackened face silently screaming in horror; countless babies and toddlers who had been stabbed or ripped apart and who had been thrown into garbage piles."
Before the massacre, it was reported that the leader of the PLO, Yasir Arafat, had requested the return of international forces, from Italy, France and the United States, to Beirut to protect civilians. Those forces had just supervised the departure of Arafat and his PLO fighters from Beirut. Italy expressed 'deep concerns' about 'the new Israeli advance', but no action was taken to return the forces to Beirut. The New York Times reported on September 1982:
Yasir Arafat, leader of the Palestine Liberation Organization, demanded today that the United States, France and Italy send their troops back to Beirut to protect its inhabitants against Israel...The dignity of three armies and the honor of their countries is involved, Mr. Arafat said at his news conference. I ask Italy, France and the United States: What of your promise to protect the inhabitants of Beirut?
The Lebanese army's chief prosecutor investigated the killings and counted 460 dead (including 15 women and 12 children), Israeli intelligence estimated 700–800 dead, and the Palestinian Red Crescent claimed 2,000 dead. 1,200 death certificates were issued to anyone who produced three witnesses claiming a family member disappeared during the time of the massacre.According to the BBC, "at least 800" Palestinians died.
Bayan Nuwayhed al-Hout in her Sabra and Shatila: September 1982 gives a minimum consisting of 1,300 named victims based on detailed comparison of 17 victim lists and other supporting evidence, and estimates an even higher total.
Robert Fisk wrote, "After three days of rape, fighting and brutal executions, militias finally leave the camps with 1,700 dead".
In his book published soon after the massacre, the Israeli journalist Amnon Kapeliouk of Le Monde Diplomatique, arrived at about 2,000 bodies disposed of after the massacre from official and Red Cross sources and "very roughly" estimated 1,000 to 1,500 other victims disposed of by the Phalangists themselves to a total of 3,000–3,500.
Lokhman Slim and Monika Borgman's Massaker, based on 90 hours of interviews with the LF soldiers who participated in the massacre, gives the participants' memories of how they were drawn into the militia, trained with the Israeli army and unleashed on the camps to take revenge for the murder of Bashir Gemayel. The motivations are varied, from blaming beatings from their fathers in childhood, the effects of the brutalization of war, obedience to one's leaders, a belief that the camp women would breed future terrorists, and the idea three quarters of the residents were terrorists. Others spoke of their violence without traces of repentance.
On 16 December 1982, the United Nations General Assembly condemned the massacre and declared it to be an act of genocide. The voting record on section D of Resolution 37/123 was: yes: 123; no: 0; abstentions: 22; non-voting: 12.
The delegate for Canada stated: "The term genocide cannot, in our view, be applied to this particular inhuman act". The delegate of Singapore – voting 'yes' – added: "My delegation regrets the use of the term 'an act of genocide' ... [as] the term 'genocide' is used to mean acts committed with intent to destroy, in whole or in part, a national, ethnic, racial or religious group." Canada and Singapore questioned whether the General Assembly was competent to determine whether such an event would constitute genocide. The Soviet Union, by contrast, asserted that: "The word for what Israel is doing on Lebanese soil is genocide. Its purpose is to destroy the Palestinians as a nation." The Nicaragua delegate asserted: "It is difficult to believe that a people that suffered so much from the Nazi policy of extermination in the middle of the twentieth century would use the same fascist, genocidal arguments and methods against other peoples."
The United States commented that "While the criminality of the massacre was beyond question, it was a serious and reckless misuse of language to label this tragedy genocide as defined in the 1948 Convention ...".
William Schabas, director of the Irish Centre for Human Rights at the National University of Ireland, stated: "the term genocide ... had obviously been chosen to embarrass Israel rather than out of any concern with legal precision".
The independent commission headed by Seán MacBride, however, did find that the concept of genocide applied to the case as it was the intention of those behind the massacre "the deliberate destruction of the national and cultural rights and identity of the Palestinian people". Individual Jews throughout the world also denounced the massacre as genocide.
The MacBride commission's report, Israel in Lebanon, concluded that the Israeli authorities or forces were responsible in the massacres and other killings that have been reported to have been carried out by Lebanese militiamen in Sabra and Shatila in the Beirut area between 16 and 18 September. Unlike the Israeli commission, the McBride commission did not work with the idea of separate degrees of responsibility, viz., direct and indirect.
Israel's own Kahan commission found that only "indirect" responsibility befitted Israel's involvement. For British journalist David Hirst, Israel crafted the concept of indirect responsibility so as to make its involvement and responsibility seem smaller. He said of the Commission's verdict that it was only by means of errors and omissions in the analysis of the massacre that the Commission was able to reach it.
The Kahan Commission concluded Israeli Defense minister Ariel Sharon bears personal responsibility "for ignoring the danger of bloodshed and revenge" and "not taking appropriate measures to prevent bloodshed". Sharon's negligence in protecting the civilian population of Beirut, which had come under Israeli control, amounted to a non-fulfillment of a duty with which the Defense Minister was charged, and it was recommended that Sharon be dismissed as Defense Minister.
At first, Sharon refused to resign, and Begin refused to fire him. It was only after the death of Emil Grunzweig after a grenade was tossed into the dispersing crowd of a Peace Now protest march, which also injured ten others, that a compromise was reached: Sharon would resign as Defense Minister, but remain in the Cabinet as a minister without portfolio. Notwithstanding the dissuading conclusions of the Kahan report, Sharon would later become Prime Minister of Israel.
The Kahan commission also recommended the dismissal of Director of Military Intelligence Yehoshua Saguy, and the effective promotion freeze of Division Commander Brig. Gen. Amos Yaron for at least three years.
The primary responsibility of the massacre is generally attributed to Elie Hobeika. Robert Maroun Hatem, Elie Hobeika's bodyguard, stated in his book From Israel to Damascus that Hobeika ordered the massacre of civilians in defiance of Israeli instructions to behave like a "dignified" army.
Hobeika was assassinated by a car bomb in Beirut on 24 January 2002. Lebanese and Arab commentators blamed Israel for the murder of Hobeika, with alleged Israeli motive that Hobeika would be ‘apparently poised to testify before the Belgian court about Sharon’s role in the massacre (see section above). Prior to his assassination, Elie Hobeika had stated "I am very interested that the [Belgian] trial starts because my innocence is a core issue."
According to Alain Menargues, on 15 September, an Israeli special operations group of Sayeret Matkal entered the camp to liquidate a number of Palestinian cadres, and left the same day. It was followed the next day, by "killers" from the Sa'ad Haddad's South Lebanon Army, before the Lebanese Forces units of Elie Hobeika entered the camps.
The US responsibility was considerable, indeed the Arab states and the PLO blamed the US. The negotiations under the mediation of US diplomat Philip Habib, which oversaw the withdrawal of the PLO from Beirut, had assigned responsibility to the American-led Multi National Force for guaranteeing the safety of those non-combatant Palestinians who remained. The US administration was criticized for the early withdrawal of the Multi National Force, a criticism which George Shultz accepted later. Shultz recounted in his memoirs that "The brutal fact is that we are partially responsible. We took the Israelis and Lebanese at their word". On 20 September the Multi National Force was redeployed to Beirut.
Ariel Sharon sued Time magazine for libel in American and Israeli courts in a $50 million libel suit, after Time published a story in its 21 February 1983, issue, implying that Sharon had "reportedly discussed with the Gemayels the need for the Phalangists to take revenge" for Bachir's assassination. The jury found the article false and defamatory, although Time won the suit in the U.S. court because Sharon's defense failed to establish that the magazine's editors and writers had "acted out of malice," as required under the U.S. libel law.
After Sharon's 2001 election to the post of Prime Minister of Israel, relatives of the victims of the massacre filed a lawsuit On 24 September 2003, Belgium's Supreme Court dismissed the war crimes case against Ariel Sharon, since none of the plaintiffs had Belgian nationality at the start of the case.
According to Robert Fisk, Osama bin Laden cited the Sabra and Shatila massacre as one of the motivations for the 1996 Khobar Towers bombing, in which al-Qaeda attacked an American Air Force housing complex in Saudi Arabia.
