BAGHDAD (Reuters) - Ten trucks transported Iraqi and foreign Islamic State fighters and their families to Iraq on Thursday as part of a prisoner handover by U.S.-backed Syrian Democratic Forces to the Iraqi army, a local mayor said.

“The majority of them are Iraqis and the convoy was under maximum security protection headed to the Jazeera and Badiya military headquarters,” said Ahmed al-Mahallawi, mayor of the Iraqi border town of al-Qaim.

Both military bases are located in Anbar province.
