Boys wounded in a car bomb attack are seen after treatment at a primary school in Mussayab, about 60km south of Baghdad.

Iraqi officials say a car bomb on a main street in a shopping area in southeastern Baghdad has killed four people.

Police officials say the explosion during rush hour Wednesday morning also wounded nine other passers-by and damaged storefronts. Hospital officials confirmed the casualties. All officials spoke on condition of anonymity because they were not authorised to release the information.

Violence has dropped dramatically across Iraq from just five years ago when the country teetered on the brink of civil war. But deadly bombs and shootings still happen nearly every day as militants try to undermine public confidence in Iraqi's government and security officials. - Sapa-AP
