The overall U.S. death toll in Iraq rose to 4,000 after four soldiers were killed in a roadside bombing in Baghdad, a grim milestone that is likely to fuel calls for the withdrawal of American forces as the war enters its sixth year.
The American deaths occurred Sunday, the same day rockets and mortars pounded the U.S.-protected Green Zone in Baghdad and a wave of attacks left at least 61 Iraqis dead nationwide.
The four soldiers with Multi-National Division Baghdad were on a patrol when their vehicle was struck at about 10 p.m. Sunday in southern Baghdad, the U.S. military said. Another soldier was wounded in the attack less than a week after the fifth anniversary of the conflict.
