At least 13 people were killed and 46 wounded when a car bomb exploded in a busy market in northeast Baghdad, police said.
The car was parked on the side of the street in Shalal market in the mainly Shi'ite Shaab district. It went off as shopkeepers were closing to break their day-long Ramadan fast.
US commanders have said they expected an increase in violence during the holy month of Ramadan which started almost two weeks ago.
It was one of the biggest attacks in Baghdad since 23 September when a car bomb killed 26 people in a Shi'ite militia stronghold in east Baghdad.
