Officials said the bomb in the New Baghdad section of the capital killed two civilians and injured three others, including a traffic officer, China's state-run Xinhua news agency reported.
Meanwhile, Iraqi police foiled a suicide attack when they forced a suicide bomber to detonate his explosives-laden vest, wounding two people, an operations command official in Salahudin province told Xinhua.
The official said police were pursuing a stolen truck just west of Samarra when the truck driver blew himself up, apparently to avoid capture. Police said they believe they prevented a potential suicide attack elsewhere in the area.
