Iraqi officials say insurgents attacks in Baghdad and northern Iraq have killed at least 40 people.
In the Iraqi capital on Sunday, gunmen in several cars opened fire on pedestrians in a religiously mixed southern district, killing seven people. A suicide car bomber also killed at least six people in a Shi'ite neighborhood, Shula of Baghdad.
Earlier, insurgents fired rockets or mortars into Baghdad's heavily-fortified Green Zone and other parts of the city. No casualties were reported in the Green Zone, but the attacks killed at least eight people in eastern Baghdad.
In northern Iraq, a suicide truck bomber killed 13 Iraqi soldiers at an army base in Mosul, while a roadside bomb killed four Iraqi soldiers in Tuz Khurmato.
The U.S. military says its forces killed 12 insurgents in a raid today in Diyala province, northeast of Baghdad.
