The U.S. military in Iraq says it is releasing more than 400 Iraqi detainees, including five women prisoners.
A military statement says the prisoners are being freed Thursday and Friday, after reviews of their cases determined there was no reason to keep holding them.
Iraqi and U.S. officials have stressed the move has nothing to do with American journalist Jill Carroll, who was kidnapped earlier this month.
Her kidnappers threatened to kill her by last Friday unless all Iraqi women detainees were released. The deadline passed with no word on her fate.
Separately, the U.S. military says one American soldier was killed and another wounded in a roadside bomb blast south of Baghdad Wednesday.
A similar bomb blast north of the capital killed three Iraqi soldiers and wounded four others.
