U.S.-backed SDF forces and the Syrian government have traded blame over the escape Monday of ISIS members from the Shaddedeh prison on the border with Iraq.

Jan 22 (Reuters) - Iraq's Supreme Judicial Council said on Thursday it would begin legal proceedings against Islamic State detainees transferred from Syria after the rapid collapse of Kurdish-led forces in northeast Syria triggered concerns over prison security.

U.S. forces moved 150 ISIS detainees from Syria to Iraq as CENTCOM began a transfer operation involving up to 7,000 radical prisoners.

Iraq began receiving ISIS prisoners on Thursday from northeastern Syria, where they had been detained by the Kurdish-led SDF.

Some 150 fighters were moved Wednesday, but thousands more could follow as tensions flare between the Syrian government and a Kurdish-led militia.

The U.S. military said it had transferred 150 Islamic State detainees from northeastern Syria to Iraq and could eventually move as many as 7,000, as the Syrian government assumes control of the region from Kurdish-led forces.

Chaos around prisons holding ISIS detainees in Syria is highlighting security risks for U.S. forces in the region.

The crisis in Syria is affecting Kurds all over the world, primarily due to the fear that members of the Syrian government’s security forces may commit abuses amid the new offensive. Kurdish protesters took to the streets across the Kurdistan Region of northern Iraq on Monday night amid increasing reports about clashes in Syria between the forces of the Syrian transitional government and those of the Kurdish-led Syrian Democratic Forces.
