An Indonesian think tank says the Syrian conflict is drawing Indonesian jihadists, particularly those affiliated with Jemaah Islamiyah. The government estimated in December that 50 Indonesians have gone to Syria to fight with the rebels. In Syria, some are said to have linked up with Ahrar al Sham, others with the Islamic State of Iraq and the Sham. Back home, some align with ISIS and others with the Al Nusrah Front. Over the past month, the Detachment 88 counterterrorism squad has conducted raids in Ciputat, South Tangerang, and Kenjeran, Surabaya, East Java. Many of the terror cells are linked to Mujahidin Indonesia Timur, which is headed by most-wanted leader Santoso.
