U.S. and Iraqi officials say car bomb attacks have killed at least four people and wounded at least 28 in northern Iraq.
Police say a bomb exploded in a parked car in the town of Qayara, south of Mosul Wednesday, killing two civilians. At least nine people were wounded in the blast.
Elsewhere, police say a suicide car bomber detonated his explosives near a convoy carrying Abdul-Karim Ali Nsaif, the mayor of the town of al-Multaqa, near the oil-rich city of Kirkuk. Officials say the bomb wounded the mayor and at least three of his bodyguards.
Police say another suicide car bomber struck an Iraqi army patrol in Mosul, killing an Iraqi soldier and a civilian and wounding at least 15 people.
In Baghdad, the U.S. military says a roadside bomb killed an American soldier and an Iraqi interpreter. The military says the explosion hit their vehicle as they were traveling in northwestern Baghdad.
In other news, Kurdish officials say the Iraqi government has urged ethnic Kurdish military forces to withdraw from an area outside the Kurdish autonomous region in northern Iraq. But the officials say they have not agreed to pull their troops out of the Kurdish-populated areas of eastern Diyala province.
A brigade of Kurdish troops patrols areas of Diyala where many Kurds live, although the province is not part of Iraq's northern Kurdistan region.
