More than 350 detainees have been freed from U.S. military prisons in Iraq in the latest series of releases.

The release — one of the largest reported this year — came on Wednesday, U.S. military officials said Friday.

It was attended by Iraqi Vice President Adel Abd al-Mahdi and Ahmad Abu Reesha, chief of Anbar Awakening Council, who addressed the men on their release. The ceremony was timed with Eid al-Fitr, the end of the monthlong Ramadan period.

The Anbar Awakening is a group of Sunni tribes that has sided with U.S. troops in recent months.

“We only want true criminals to remain in detention rather than the innocent, and we are seriously working towards that goal,” al-Mahdi was quoted as saying.

The prisoners are screened and released when they are “deemed to be no longer an imperative threat,” officials said.

In a separate statement earlier this week, the U.S. military talked of “re-education” programs and other efforts to rehabilitate the prisoners who will eventually be released.
