More than 200 detainees were released Sunday from Abu Ghraib (search) prison after a security review deemed them no longer a threat, the U.S. military said.

It was the fifth round of releases since a review board set up by coalition forces and the interim Iraqi government began work in August following a torture scandal at the detention facility.

"We released about 250 detainees today. There were no "high-profile" detainees that I'm aware of — definitely no high-value detainees and no women," said spokesman Lt. Col. Barry Johnson.

In April, publication of photographs showing naked, terrified Iraqi prisoners being abused and humiliated by grinning American guards at Abu Ghraib caused outrage in Iraq and internationally.

More than 1,000 detainees have been released since August.
