The violence, which left 65 others wounded, comes amid a protracted surge in violence just months ahead of general elections that has forced Iraqi officials to appeal for international help in combating the country’s worst unrest since 2008.
At least seven explosions, including six car bombs, hit Shiite Muslim neighborhoods of the Iraqi capital, according to security and medical officials, from about 7:30 a.m. (0430 GMT) onwards.
They come after similarly coordinated bombings in Baghdad on Sunday evening left 21 dead.
Wednesday’s attacks occurred in areas ranging from the city’s main commercial district of Karrada to the predominantly Shiite neighborhood of Shaab, as well as Sadriyah, one of Baghdad’s oldest areas.
One car bomb also went off in the Sunni-majority neighbourhood of Adhamiyah in north Baghdad, the officials said.
Security forces imposed tough measures in areas hit by attacks, in many cases barring journalists from filming video or taking photographs at bombing sites.
No group immediately claimed responsibility for the violence, but Sunni militants linked to Al-Qaeda’s front group often set off coordinated bombings across Baghdad, typically targeting Shiites, whom they regard as apostates.
