Iraqi and U.S. officials say insurgents killed at least 33 people on Sunday in a wave of attacks across Iraq.
The U.S. military says two suicide car bombs killed 14 people near a U.S. base in western Baghdad. Several other car bombs in the capital killed at least 14 more people, including two American soldiers.
To the north, a car bomb killed two Iraqis in Mosul and a roadside bomb in Udaim killed three bodyguards assigned to Iraqi Foreign Minister Hoshyar Zebari.
The violence came as Iraq's parliament met for a third time as lawmakers try to agree on a cabinet. But a Shi'ite political party and a Sunni Arab bloc both threatened to pull out of any future unity government because of differences over which group should get which ministries.
Iraqi authorities also found the bodies of five blindfolded men with gunshot wounds near Karbala.
And the British Defense Ministry announced on Sunday that two British soldiers were killed late Saturday in a roadside bomb in the southern city of Basra.
