These kind of allegations need to be verified, but damn, the administration has handled this so poorly that it's made the climate ripe for these kind of stories to have legs even when they're so far unsubstantiated:
The US military has said it will investigate claims by a former inmate of Abu Ghraib prison that a girl as young as 12 was stripped and beaten by military personnel.... She was naked and screaming and calling out to him as they beat her. Her brother was helpless and could only hear her cries. This affected all of us because she was just a child. - ITV
