A car bomb detonated in the middle of a busy market in central Baghdad killed at least 11 people and wounded 64 on Friday, police and hospital officials said.
At least one woman and a child were killed in the blast, a police officer said on condition of anonymity as he was not authorized to talk to the press.
The popular market in Tayaran Square - which has been targeted by insurgents in the past - was full of shoppers heading home from Friday prayers.
The bombing comes at the end of a relatively quiet holiday period in Iraq's capital.
Violence across the country is down nearly 60 percent, according to the US military, largely because of an influx of American troops in the capital and the growth of anti-al-Qaida in Iraq groups in Anbar province and elsewhere.
