Description: The Department of State designated Jemaah Anshorut Tauhid (JAT) as a Foreign Terrorist Organization on March 13, 2012. Formed in 2008, the Indonesia-based group seeks to establish an Islamic caliphate in Indonesia and has carried out numerous attacks on Indonesian government personnel, police, military, and civilians. In 2011, Abu Bakar Ba’asyir, the founder and leader of JAT, was sentenced to 15 years in prison for his role in organizing a militant training camp in Aceh. Ba’asyir is also the co-founder and former leader of Jemaah Islamiya (JI). JAT maintains ties to JI and other terrorist groups in Southeast Asia.
Activities: JAT has conducted multiple attacks targeting civilians and Indonesian officials, resulting in the deaths of numerous Indonesian police and innocent civilians. In December 2012, four police officers were killed and two wounded in an attack by suspected local JAT members in Central Sulawesi. Since Abu Bakar Ba’asyir’s pledge of allegiance to ISIS in 2014, many JAT members have joined Indonesia’s ISIS-affiliated groups, while others have joined al‑Qa’ida‑affiliated groups. Although JAT did not publicly claim any attacks in 2016 or 2017, JAT members are believed to have been involved in ISIS operations in Southeast Asia.
Strength: JAT is estimated to have several thousand supporters and members, although internal disagreements over aligning with ISIS have likely reduced its membership.
Location/Area of Operation: The group is based in Indonesia.
Funding and External Aid: JAT raises funds through membership donations and legitimate business activities. JAT has also conducted cyber hacking, robbed banks, and carried out other illicit activities to fund the purchase of assault weapons, ammunition, explosives, and bomb‑making materials.
