A wave of car bomb attacks has hit busy shopping areas and markets in Baghdad, targeting mainly Shia areas in the Iraqi capital.
Sixty-six people were killed in the series of explosions on Monday and many more were wounded, the BBC reports.
More than a dozen bombs exloded, one striking the busy commercial Sadoun Street in central Baghdad, where a bystander said a four-year-old child was among the victims.
No group has said it carried out the attacks, but tension between the Shia Muslim majority, which leads the government, and minority Sunnis has been growing since last year, the BBC reports.
Monday's bombings come a week after more than 70 people were killed and many others injured in a series of attacks across the country, in what was described as one of the worst days for sectarian violence in Iraq for several years.
Baghdad was worst hit, with several explosions at bus stations and markets in mainly Shia Muslim districts.
