In addition, Abdul Satar Balasm, an employee of agriculture ministry, was killed when gunmen using weapons fitted with silencers attacked his car in Amil district in southwestern Baghdad, he said.
In Iraq's northern central province of Salahudin, a motorcycle packed with explosives went off in the city of Baiji, some 200 km north of Baghdad, killing one civilian and wounding four others, a provincial police source anonymously told Xinhua.
