Seven people from the same family were killed by bomb blasts near their home in the town of Mussayab, south of Baghdad.
In the Shi'ite majority city of Hilla in the north, a parked car bomb went off near the convoy of the governor of Babil province, missing him but killing another person, police said.
A series of blasts in Iraq's disputed territories, over which both the central government and the autonomous Kurdish region claim jurisdiction, killed three people.
Two of those deaths were in the oil-rich, ethnically mixed city of Kirkuk, where a bomb exploded as a police team tried to defuse it.
Violence in Iraq has eased since the carnage of 2006-2007, but attacks still take place on an almost daily basis.
