The Pentagon has concluded its investigation into the shooting deaths of civilians in the Iraqi city of Haditha at the hands of US Marines. On Wednesday, Democratic Congressmember John Murtha of Pennsylvania said the probe will show that Marines: “killed innocent civilians in cold blood.” Iraqis say 15 villagers were killed after US troops shot them in their homes. The dead included three children. The Pentagon initially claimed the civilians had died in a roadside bombing. But Murtha said: “There was no firefight. There was no improvised explosive device that killed those innocent people. Our troops overreacted because of the pressure on them. And they killed innocent civilians in cold blood. That is what the report is going to tell.”
