Overview: Indonesia applied sustained pressure to detect, disrupt, and degrade terrorist groups operating within its borders and deny them safe haven. ISIS-affiliated Jamaah Ansharut Daulah (JAD) and its offshoots continued to target police and other symbols of state authority. The capability of terrorist groups to launch coordinated mass casualty attacks was assessed as low, but the intent remained high. Failed plots included attempts by terrorist groups to use low-grade radioactive material for bombs and recruit female suicide bombers. Returning foreign terrorist fighters with new operational training, skills, experience, networks, and access to funding could help launch more sophisticated attacks against Indonesian government personnel or facilities, Western targets, and other soft targets and public spaces.
