Disunity among Indonesian ISIS Supporters and the Risk of More Violence, the latest report from the Institute for Policy Analysis of Conflict (IPAC), looks at the Jakarta attack on 14 January 2016 in the context of rivalry among Indonesian ISIS leaders in Syria and different pro-ISIS groups in Indonesia. The bombing and shooting in Indonesia’s capital killed four civilians and four terrorists.
“The Jakarta attack is now known to have been locally organised – not directed from Syria as originally thought – but it almost instantly resulted in instructions from a Syria-based leader to his followers to do one better,” says Sidney Jones, IPAC director. “Leaders of Indonesia’s tiny pro-ISIS camp are competing to prove their fighting credentials.”
The report examines how these rivalries emerged. The Jakarta attack appears to have been carried out by members of a group known as Partisans of the Caliphate (Jamaah Anshar Khilafah, JAK), whose ideological leader is detained cleric Aman Abdurrahman. Aman has fallen out with the top Indonesian in Syria, Bahrumsyah, who commands Katibah Nusantara, the main Indonesian-Malaysian military unit in ISIS. He is close to Bahrumsyah’s rival, Abu Jandal, who heads a dissident unit. Bahrumsyah is the Indonesian with best access to central ISIS leaders and funds, but the fact that official ISIS media claimed credit for the Jakarta attacks may have boosted Abu Jandal’s position.
