The U.S. military confirmed Wednesday that a former Guantanamo detainee from Kuwait carried out a recent suicide attack in northern Iraq.

A spokesman for U.S. military's Central Command told The Associated Press that Abdallah Salih al-Ajmi took part in an attack in Mosul.

U.S. Navy Cmdr. Scott Rye said authorities don't know the motive for the attack, which was reported last week by Dubai-based Al-Arabiya television. Iraqi security forces were apparently targeted.
