A series of roadside bombs and shootings killed nine people, including two policemen and three worshippers, in and around Baghdad on Sunday, security officials said.
Twenty people were also wounded in the violence, the latest in a surge of killings in August and as Muslims observe the holy fasting month of Ramadan, when insurgents typically step up their attacks, fuelling security concerns as the United States continues to withdraw its troops.
In a pre-dawn attack, three Sunni Muslims were gunned down as they exited the Abid Wais mosque in Jurf al-Sakhr, 50 kilometres (30 miles) south of the capital in Babil province, police said.
The drive-by shooting, which also left one person wounded, took place at 4:00 am (0100 GMT), after worshippers completed Ramadan prayers which followed a communal meal ahead of a day-long fast.
Jurf al-Sakhr lies within a confessionally mixed region known as the Triangle of Death because of the frequency of insurgent attacks during the worst of Iraq's violence following the 2003 US-led invasion.
Three others, including an off-duty policeman, were killed when the minibus they were on was struck by a bomb attack as it travelled to the centre of Baghdad from its eastern quarter, an interior ministry official said.
