In Baghdad, civil defence Colonel Mohammed Yunis was killed and his wife and two children were wounded when gunmen opened fire on the family's car just outside the capital's heavily-fortified Green Zone, home to parliament and the US embassy, an interior ministry official and a medical source said.
And in the west Baghdad neighbourhood of Saidiyah, gunmen shot at Assad Mohammed, an official in the office of deputy parliament speaker Qusay al-Sohail, with Mohammed dying of his wounds in hospital, the officials said.
Outside the northern city of Kirkuk, gunmen on a motorcycle killed an Iraqi soldier, a local police official and Doctor Mohammed Abdullah from Kirkuk hospital said.
And in Baladruz, in the central province of Diyala, a roadside bomb blew up near a car, killing one civilian and wounding two others, according to a police colonel.
A doctor in the main hospital in provincial capital Baquba confirmed receiving the body and treating the wounded.
Violence in Iraq has declined dramatically since its peak in 2006-2007, but attacks remain common, especially in Diyala. A total of 132 Iraqis were killed in violence in May, according to official figures.
