A suicide bomber has blown himself up inside a Shiite mosque north of Baghdad, killing 14 and wounding 32 others, according to Iraqi officials.
Police said the attacker struck on Saturday evening in the village of Sabaa al-Bour, about 20 miles north of Baghdad.
Medical officials confirmed the casualty figures.
The attacks and several others elsewhere that killed nine are the latest in a wave of violence that has killed more than 2,000 Iraqis since the start of April. It is the bloodiest and most sustained spate of violence to hit Iraq since 2008.
There was no immediate claim of responsibility, but al Qaida's Iraq arm and other Sunni extremists frequently target Shiites.
Earlier in al-Athba village near the northern city of Mosul, a suicide car bomber rammed his explosives-laden car into a police patrol. Three civilian bystanders and one policeman died while six other people were wounded, he added.
In the city of Tuz Khormato, 130 miles north of Baghdad, gunmen on motorcycles riddled a civilian vehicle carrying four off-duty policemen with bullets, killing three and wounding another, said a police officer.
Another group of gunmen attacked a police checkpoint in the city of Samarra, killing two policemen and wounding four, another police officer said. Samarra is 60 miles north of Baghdad.
Police also said two civilians were killed and nine wounded when a bomb ripped through a small market late on Friday in Baghdad.
