Description: Designated as a Foreign Terrorist Organization on October 23, 2002, Jemaah Islamiya (JI) is a Southeast Asia-based terrorist group co-founded by Abdullah Sungkar and Abu Bakar Ba'asyir that seeks to establish an Islamic caliphate spanning Indonesia, Malaysia, southern Thailand, Singapore, Brunei, and the southern Philippines. More than 400 JI operatives have been captured since 2002, including operations chief and al-Qa'ida associate Hambali. In 2006, several members connected to JI's 2005 suicide attack in Bali were arrested; in 2007, Muhammad Naim (a.k.a. Zarkasih) and JI military commander Abu Dujana were arrested; and in 2008, two senior JI operatives were arrested in Malaysia and a JI-linked cell was broken up in Sumatra. In September 2009, JI-splinter group leader Noordin Mohammad Top was killed in a police raid. In February 2010, the Indonesian National Police discovered and disbanded a violent extremist training base in Aceh in which former members of JI and other Indonesian violent extremist groups participated. The police raid resulted in the capture of more than 60 militants, including some former JI operatives, and led authorities to former JI senior operative Dulmatin, one of the planners of the 2002 Bali bombing. In March 2010, Dulmatin was killed outside of Jakarta. In January 2011, JI member Umar Patek was captured in Abbottabad, Pakistan, and put on trial in Indonesia, where he was convicted and sentenced to 20 years in prison in June 2012 for his role in the Bali bombing.
Activities: In December 2001, Singaporean authorities uncovered a JI plot to attack U.S., Israeli, British, and Australian diplomatic facilities in Singapore. Other significant JI attacks include the 2002 Bali bombings, which killed more than 200, including seven U.S. citizens; the August 2003 bombing of the J.W. Marriott Hotel in Jakarta; the September 2004 bombing outside the Australian Embassy in Jakarta; and the October 2005 suicide bombing in Bali, which killed 26, including the three suicide bombers.
On July 17, 2009, a JI faction led by Top conducted the group's most recent high-profile attacks, when two suicide bombers detonated explosive devices at the J.W. Marriott and Ritz-Carlton hotels in Jakarta that killed seven and injured more than 50, including seven Americans. The Philippine military announced it had killed two JI members in separate incidents in the south of the country in late 2012, including one of the group's senior-most representatives to the Philippines.
In November 2014, Indonesian authorities released former JI bomb-maker Taufik Abdul Halim from prison after serving a 12-year sentence for attempting to bomb a Jakarta shopping mall in 2001.
Strength: Estimates of total JI members vary from 500 to several thousand.
Location/Area of Operation: JI is based in Indonesia and is believed to have elements in Malaysia and the Philippines.
Funding and External Aid: JI fundraises through membership donations and criminal and business activities. It has received financial, ideological, and logistical support from Middle Eastern contacts and illegitimate charities and organizations.
