At least 11 people have been killed in Iraq in a wave of attacks on people who have opposed insurgents, police say.
The bombings and shootings happened in a number of places across the country, and targeted police officers and a militia group.
Civilians were also among those killed or wounded, reports said.
Insurgent attacks have killed hundreds since March following inconclusive elections.
Many of the attacks were targeted at the Sunni militia known as the Shawa or Sons of Iraq.
The group were former allies of al-Qaeda during the the sectarian violence between 2006 and 2007, before they turned against them.
Victims of the attacks included a Sunni Imam from the Shawa militia and two of his sons, who were killed by gunmen in Abu Ghraib, west of Baghdad.
A bomb rigged with bags of ball bearings killed three civilians in a Baghdad shopping district.
Also among the dead was a Christian man, shot 15 times in a drive-by attack on a street in the northern city of Kirkuk.
