Nearly a dozen explosions have torn through predominantly Shi'ite Muslim areas in and around the Iraqi capital, killing at least 39 people.
The attacks are part of a wave of violence that has washed across Iraq since a deadly security crackdown on a Sunni protest camp in April. Since then, the bloodshed has reached heights unseen since the country teetered on the brink of civil war in 2006 and 2007.
There was no immediate claim of responsibility for Sunday's attacks, but insurgent groups frequently target civilians in cafes and public areas of Shi'ite neighbourhoods in an attempt to undermine confidence in the Shi'ite-led government and stir up Iraq's already simmering sectarian tensions.
The deadliest attack took place in the mostly Shi'ite neighbourhood of Baiyaa, where a car bomb exploded inside an car shop, killing seven people and wounding 14 others, police say.
Another car bomb in a commercial street in downtown Baghdad killed four more people, while in the eastern Ghadeer district another car bomb near a government tax office killed six people and wounded 22.
Saad Maan Ibrahim, an Interior Ministry spokesman said the attacks bear the hallmark of al-Qaeda's Iraqi branch.
Medical officials confirmed the casualty figures for all attacks. All officials spoke on condition of anonymity because they are not authorised to speak to the media.
At least 127 people have died in attacks in Iraq so far this month, according to an Associated Press count.
