London: Military police are investigating an abuse allegation after a newspaper reported an Iraqi youth claimed troops made him perform a sex act on another prisoner in 2003, the Ministry of Defence said.

The Independent on Sunday said the youth claims he was forced to perform a sex act on another youth by British forces in May, 2003 at a base in southern Iraq called Camp Bread Basket.

Four British servicemen have been jailed over photographs taken at the camp which showed troops beating prisoners who were tied up and forcing others to pose in sexually humiliating positions.
