BAGHDAD (AP) -- Officials in Iraq say at least four people are dead after bombs in Baghdad struck a taxi and a double-decker bus.
They say the bus was carrying employees of Iraq's Housing Ministry. Seven people were injured.
Iraqi police arrested one man at the site of the blast. A military spokesman says Shiite extremists are suspected in the attack.
In a separate blast, a bomb placed under a taxi exploded at a square in east Baghdad, killing two people. At least two others were injured.
The U.S. military, meanwhile, has announced the death of Marine yesterday in a non-combat incident at an air base in western Iraq. The incident is being investigated.
