[JURIST] An investigation conducted by the US Navy Criminal Investigation Services [official website] has found no evidence to support allegations that Australian Guantanamo Bay detainees were abused.

Hicks was taken into custody in August 2001, and is still awaiting trial by a military commission on charges of conspiracy, attempted murder and aiding the enemy. Habib was released [JURIST report] in January after three years in custody at the terror suspect detention camp, and has since alleged that he was mistreated at the hands of US authorities. Reuters has more. Mamdouh Habib is sticking by his abuse claims [Australian Broadcasting Corporation report] following the US military report's release.
