Two roadside bomb attacks have killed five U.S. soldiers in Iraq, according to the U.S. military.
Four Task Force Lightning Soldiers were killed and two others were wounded Sunday when a bomb exploded near their patrol in Diyala Province, the military said.
Another U.S. soldier was killed and two others were wounded Sunday by a roadside bomb blast in northwest Baghdad, the military said. The soldier was involved in a route-clearance mission, the military said.
The deaths brought to 3,233 the number of U.S. troops killed in the Iraq war. Seven American civilian contractors of the military also have died in the conflict.
Also on Sunday, a battle between insurgents and the Iraqi Army erupted in a Sunni section of central Baghdad, with the U.S. military called in to provide air support during the hourlong firefight, an Iraqi Interior Ministry official said.
The fighting began at around 1:30 p.m. when insurgents attacked an army checkpoint near a market in the al-Fadhil district, the official said.
At least two civilians were killed and four people were wounded, including two Iraqi soldiers, the official said.
The streets are narrow in the al-Fadhil district, one of Baghdad's oldest neighborhoods. It has frequently been a battleground between Sunni insurgents and Iraqi security forces.
Elsewhere in Iraq Sunday, a roadside bomb struck an Iraqi police patrol in the northern Iraqi city Tikrit around noon, killing one police officer and wounding several others, according to a Tikrit police official.
