OVERVIEW

Jemaah Islamiya Flag

Jemaah Islamiyah (JI) is an al-Qa‘ida–linked terrorist group based in Indonesia that killed hundreds of people in several high-profile attacks in Indonesia during the early 2000s. The group has conducted fewer attacks since then, but it remains committed to its goal of establishing an Islamic state in Indonesia and is focusing on propagating its ideology through propaganda, educational indoctrination, and political activism. Some JI members have traveled to conflict zones, such as Afghanistan, Syria, and the southern Philippines, to join local terrorist or militant groups, potentially providing JI a militant capability if the group or elements among its supporters decide to resume terrorist attacks.
