More than 30 people have been killed and more than 60 have been injured in car bombings that hit at least eight areas in Baghdad.
Officials said one of the bombs exploded near the fortified Green Zone diplomatic complex, killing at least four people and injuring 12.
Some of the bombings targeted Shi'ite neighborhoods, others mixed Shi'ite-Sunni areas.
No one has claimed responsibility.
There has been a sharp rise in sectarian violence in Iraq in recent months against a backdrop of protests by the Sunni minority against the Shi'ite-led government.
The increased violence has raised fears of a return to the sectarian bloodshed that brought the country to the edge of civil war between 2006-08.
