Iraqi officials say a car bombing in a commercial area of a Shiite neighborhood in Baghdad has killed at least 15 civilians.

A police officer says Thursday's explosion in the district of New Baghdad in the Iraqi capital also wounded up to 35 civilians. He says that the explosives-laded car was parked in a crowded area and that the casualty figures could be higher.

A medical official confirmed the casualty figures. Both officials spoke on condition of anonymity as they were not authorized to brief the press.

No one immediately claimed responsibility for the attack. The Islamic State, a Sunni extremist group, often targets Iraq's Shiite majority. The Iraqi capital has seen near-daily attacks in recent weeks.
