Jemaah Islamiah (Arabic: الجماعة الإسلامية‎‎, al-Jamāʿat ul-Islāmíyatu, meaning "Islamic Congregation", frequently abbreviated JI) is a Southeast Asian militant extremist Islamist terror group dedicated to the establishment of a Daulah Islamiyah (regional Islamic caliphate or state) in Southeast Asia. On October 25, 2002, immediately following the JI-perpetrated Bali bombing, JI was added to the UN Security Council Resolution 1267 as a terrorist group linked to al-Qaeda or the Taliban.

JI is a transnational organization with cells in Thailand, Singapore, Malaysia and the Philippines. In addition to al-Qaeda the group is also thought to have links to the Moro Islamic Liberation Front and Jamaah Ansharut Tauhid, a splinter cell of the JI which was formed by Abu Bakar Baasyir on July 27, 2008. The group has been designated as a terrorist groups by the United Nations, Australia, Canada, China, Kazakhstan, Russia, the UAE, the United Kingdom and the United States. It remained very active in Indonesia where it publicly maintained a website as of January 2013.

JI has its roots in Darul Islam (DI, meaning "House of Islam"), a radical Islamist/anti-colonialist movement in Indonesia in the 1940s.

The JI was established as a loose confederation of several Islamic groups. Sometime around 1969, three men, Abu Bakar Bashir, Abdullah Sungkar and Shahrul Nizam 'PD' began an operation to propagate the Darul Islam movement, a conservative strain of Islam.

Bashir and Sungkar were both imprisoned by the New Order administration of Indonesian president Suharto as part of a crackdown on radical groups such as Komando Jihad, that were perceived to undermine the government's control over the Indonesian population. The two leaders spent several years in prison. After release, Bashir and his followers moved to Malaysia in 1982. They recruited people from Indonesia, Malaysia, Singapore, and the Philippines. The group officially named itself Jemaah Islamiah around that time period.

JI was formally founded on January 1, 1993, by JI leaders, Abu Bakar Bashir and Abdullah Sungkar while hiding in Malaysia from the persecution of the Suharto government. After the fall of the Suharto regime in 1998, both men returned to Indonesia where JI gained a terrorist edge when one of its founders, the late Abdullah Sungkar, established contact with Osama bin Laden's al-Qaeda network.

JI's violent operations began during the communal conflicts in Maluku and Poso. It shifted its attention to targeting US and Western interests in Indonesia and the wider Southeast Asian region since the start of the US-led war on terror. JI's terror plans in Southeast Asia were exposed when its plot to set off several bombs in Singapore was foiled by the local authorities.

In 2004, Abu Bakar Bashir created the Indonesian Mujahedeen Council to connect Islamist groups, including JI, in Indonesia.

Recruiting, training, indoctrination, financial, and operational links between the JI and other militant groups, such as al-Qaeda, the Abu Sayyaf Group (ASG), the Moro Islamic Liberation Front (MILF), the Misuari Renegade/Breakaway Group (MRG/MBG) and the Philippine Rajah Sulaiman movement (RSM) have existed for many years.

Bashir became the spiritual leader of the group while Hambali became the military leader. Unlike the Al-Mau'nah group, Jemaah Islamiah kept a low profile in Malaysia and their existence was publicized only after the 2002 Bali bombings.

Designation as terrorist group

Jemaah Islamiyah has been designated a terrorist group by the following countries and international organizations:

  •  Australia
  •  Canada
  •  United Kingdom
  •  United Nations
  •  United States
  • Other state opponents

  •  Indonesia
  •  Malaysia
  •  Philippines
  • 2002 Bali bombing

    Prior to the first Bali bombing on October 12, 2002, there was underestimation to the threat Jemaah Islamiah posed. After this attack, the U.S. State Department designated Jemaah Islamiah as a Foreign Terrorist Organization.

    Other terrorist attacks

    In 2003, Indonesian police confirmed the existence of "Mantiqe-IV"  the JI regional cell which covered Irian Jaya and Australia. Indonesian police said Muklas has identified Mantiqe IV's leader as Abdul Rahim—an Indonesian-born Australian. Jemaah Islamiah is also strongly suspected of carrying out the 2003 JW Marriott hotel bombing in Kuningan, Jakarta, the 2004 Australian embassy bombing in Jakarta, the 2005 Bali terrorist bombing and the 2009 JW Marriott and Ritz-Carlton hotel bombings. The Bali and JW Marriott attacks showed that JI did not rule out attacking the same target more than once. The JI also has been directly and indirectly involved in dozens of bombings in the southern Philippines, usually in league with the ASG.

    However, most of Jemaah Islamiah prominent figures such as Hambali, Abu Dujana, Azahari Husin, Noordin Top and Dulmatin have either been captured or killed, mostly by Indonesian anti-terrorist squad, Detachment 88. While several of its former leaders, including Malaysian Islamic extremist and Afghanistan War veteran Nasir Abbas, have renounced violence and even assisted the Indonesian and Malaysian governments in the war on terrorism. Nasir Abbas was Noordin Top's former superior.

    Indonesian investigators revealed the JI's establishment of an assassination squad in April 2007, which was established to target top leaders who oppose the group's objectives, as well as other officials, including police officers, government prosecutors and judges handling terrorism-related cases.

    In April 2008, the South Jakarta District Court declared JI an illegal organisation when sentencing former leader Zarkasih and military commander Abu Dujana to 15 years on terrorism charges.

    In 2010 Indonesian authorities cracked down on the Jemaah Islamiah network in Aceh. Between February and May 2010, more than 60 militants were captured. This Aceh network was established by Dulmatin sometime after 2007 when he returned to Indonesia.


    Jemaah Islamiyah's name roughly translates to "Islamic Community" in English and is abbreviated as JI. To counter recruitment efforts by the group, Islamic scholars in Indonesia and the Philippines who were critical of the group called for the group to be called Jemaah Munafique (JM) instead which translates as "Evil Community".
