Trials of IS Fighters in Syria Suspended Indefinitely Heather Murdock HASSEKA, SYRIA - "It's like we are holding a ticking bomb in our hands," a guard in a prison in northeastern Syria told us in February. The facility holds roughly 5,000 accused Islamic State militants from all over the world. A month later, the metaphorical bomb went off. Prisoners rioted on Sunday, overrunning one floor of the prison and smashing interior doors. Later that night, wearing a black mask and flanked by men carrying AK-47s, Rubar Hassan, the prison's director, appeared before news cameras, appealing for international help. More than a year after the territorial defeat of IS in Syria, officials here still feel baffled and betrayed by the international community. Watch: Related video by Heather Murdock .
