In other Iraq news, a military probe has found evidence that backs allegations US Marines massacred 24 Iraqi civilians in Haditha last November. The Marines initially claimed that 15 civilians died in a roadside blast caused by insurgents. Months later, reports emerged the civilians were killed when marines burst into their homes and shot them dead in their nightclothes. An ongoing probe is examining whether Marine commanders tried to cover up the events. The news comes as a Marine has filed suit against Democratic Congressmember John Murtha for claiming the Haditha killings were deliberate.
