In the deadliest attack, a blast at a popular market in eastern Baghdad's Shia Sadr City slum killed at least ten people and wounded 65, police said.
Another car bomb blew up next to a group of labourers queuing for work, killing six people and wounding 16.
Two other blasts shook a market area of Husseiniya, on Baghdad's northern outskirts, killing four, and a street in eastern Baghdad, apparently targeting the convoy of an Interior Ministry official, killing one of his guards and a bystander.
