In 2012, ISIS’ appeal started to grow among Indonesian and Malaysian civil society groups that had mobilized in response to Syria’s humanitarian crisis by creating local awareness and fundraising. Within a year, several Islamic preachers in Indonesia had pledged allegiance to ISIS’ caliphate, and about half a dozen graduates from Indonesia’s Ngruki Islamic boarding school, previously a hotbed of Jemaah Islamiyah membership ideology and recruitment, are believed to have left to join the jihad in Syria (often with funding from Jemaah Islamiyah and other affiliated extremist groups).
Later in the article it explains that unlike returning fighters from Afghanistan in the early 90s, the current fighters have lost the advantage of surprise. Security forces will be monitoring the problem much more closely.

The Islamic State’s (ISIS) media wing, Al-Hayat Media Center, recently released a video entitled “Join the Ranks” that features a group of Indonesian foreign fighters in Syria. In the video, the charismatic Indonesian militant Bahrumsyah calls on his fellow Indonesian Muslims to migrate to the land of the “caliphate.”[1] It is estimated that 100 to 300 Indonesian militants have gone to fight in Syria.[2] While some are spread across al-Qa‘ida (AQ)-affiliated groups such as Ahrar Sham, this essay focuses specifically on links between Indonesian militants and ISIS. Indonesians and Malaysians fighting for ISIS appear to have formed their own military unit, the Katibah Nusantara.[3] Meanwhile, 2,000 people across the Indonesian archipelago pledged allegiance to ISIS earlier this year.[4]
