Gunmen killed four people and injured another in two attacks in the Iraqi capital on Tuesday morning, a well-informed police source said.
Unknown gunmen opened fire on a car in Haifa Street, in central Baghdad, killing two civilians and injuring another, the source told Xinhua on condition of anonymity.
One of the victims was Musa Jaafar, top geology surveyor working for the government, the source said.
In a separate attack, gunmen opened fire on civilians in Baghdad's western neighborhood of Hay Dragh, leaving two civilians dead, he added.
Earlier, two civilians were killed and 10 others injured by a car bomb and a roadside bomb attack in the Iraqi capital, police said.
Violence persists in Baghdad although the U.S. and Iraqi officials announced a steep drop of violence in the capital as a result of a major security plan aimed at checking the insurgency and sectarian strife in Baghdad.
