The U.S. military is fighting efforts to release more photos and videotapes that document the abuse of detainees at Iraq's Abu Ghraib prison.
General Richard Myers, chairman of the Joint Chiefs of Staff, warns that releasing the images would inflame Arab opinion and put U.S. troops at risk.
He also argues that al-Qaida and other groups would use the photos for propaganda.
General Myers' statements were contained in recently-unsealed court papers filed in U.S. district court in New York City.
The American Civil Liberties Union has sued the government for the release of 87 photos and four videotapes taken at the U.S.-run Abu Ghraib prison. The group says release of the images will lead to a public examination of Army interrogation policies.
Photos from Abu Ghraib released last year showed Iraqi detainees with leashes around their necks and in other humiliating positions.
