New photographs have emerged showing U.S. soldiers abusing Iraqi detainees. One photo shows Navy SEALs sitting on top of hooded and handcuffed detainees. Another shows an Iraqi being held with a gun to his head. Several photos appeared to show bloodied prisoners. The photos appear to have been taken by soldiers in May 2003 which would make them the earliest documented proof of prisoner abuse in Iraq. The Pentagon has launched a criminal investigation. John Hutson, a retired rear admiral said the taking of the photos was illegal under the Geneva Conventions which prohibits souvenir photos of prisoners of war.
