Newly released U.S. Army documents indicate American abuse of detainees in Iraq was more widespread than previously reported.

Documents obtained Friday by the American Civil Liberties Union indicate that a U.S. investigating officer concluded that detainees were being "systematically and intentionally mistreated" at a U.S. Army holding facility in Mosul in late 2003. That was around the same as the prisoner abuse Abu Ghraib prison near Baghdad.

The ACLU says the 1200 pages of Army documents detail torture and abuse, including beatings, excessive physical exercise, loud music and the wearing of hoods. One prisoner died and another's jaw was broken.

No one was punished because military investigators were unable to determine which guards were responsible.

Army officials say the documents show they quickly responded to some of the abuses to prevent recurrences. But the ACLU says the investigations have been less than thorough.
