Iraq 'Death Squad Caught in Act'

Iraq has launched an investigation into claims by the US military that an Iraqi interior ministry "death squad" has been targeting Sunni Arab Iraqis. Hundreds of Sunni Arab Iraqis have been found dead since the 2003 war in what appear to have been extra-judicial killings. On Wednesday, the bodies of four unidentified men were found in Baghdad's Shia district of Shula. They had been handcuffed, blindfolded and shot in the head.
