Syrian Kurdish forces tighten siege after Islamic State prison break

AMMAN (Reuters) - Kurdish-led Syrian Democratic Forces (SDF) troops aided by U.S. troops tightened their siege of a prison housing Islamic State suspects after inmates took over the facility, residents and officials said on Sunday.

Dozens of inmates were killed in the attack on the prison in northeastern Syria, which began on Thursday. Militants detonated a car bomb near the prison gates, helping dozens of inmates flee to the neighbouring Ghweiran district of al-Hasaka, witnesses and officials said.
