Bombs struck a double-decker bus and a taxi in eastern Baghdad on Monday, killing four people, authorities said. Iraqi police and hospital officials said the bus was carrying employees of Iraq's Housing Ministry through the Shiite-dominated neighborhood of Mashtal when it was hit by a roadside bomb.
Two people died in that attack, said the officials,according to the AP. Seven people were wounded and brought to Baghdad's Kindi hospital.
The U.S. military said the explosion destroyed the bus and confirmed that seven people were wounded, but said only one was killed. Iraqi police arrested one man at the site of the blast, said Lt. Col. Steven Stover, a military spokesman.
In a separate attack, a bomb placed under a taxi exploded at Maysaloun Square in east Baghdad, police said. Police and health officials said two people were killed and two injured.
The American military, meanwhile, said in a statement that a U.S. Marine died Sunday in a non-combat incident at Asad Air Base in the west of Iraq.
