Iraqi officials say seven people were killed and 25 wounded when a parked car exploded in the Sadr City slum in eastern Baghdad.
Police and hospital officials tell the Associated Press that the blast Wednesday evening took place near a popular cafe where young people were gathered.
The casualty figures were given by a Sadr City police officer and an official at the Imam Ali hospital, where the wounded were taken. Both spoke on condition of anonymity because they were not authorized to disclose information with the media.
Sadr City is the eastern Baghdad stronghold of anti-American cleric Muqtada al-Sadr and the scene of one of Iraq's most deadly bombings this year, when insurgents in April targeted worshippers gathered for Friday prayers.
