Bomb attacks hit the Iraqi capital Baghdad and a village near the northern town of Baquba on Wednesday, killing at least 52 people.
In the deadliest incident, a bomb blew up in a funeral tent where mourners were marking the death two days ago of a pro-government militiaman, police said. It killed 18 people and wounded 16 in Shatub, a village south of Baquba.
Police and medics said that half a dozen car bombs exploded across the Iraqi capital on Wednesday, mostly in Shiite districts, killing 34 people and wounding 71.
Al-Qaeda-linked militants are pursuing a campaign of attacks, mostly directed at state targets civilians loyal to the government.
The violence occurred amid a continuing standoff between the Iraqi army and militants who overran the city of Falluja west of Baghdad more than two weeks ago in a challenge to Prime Minister Nuri al-Maliki's government.
