A civilian was killed and three others were wounded in two bomb explosions in Baghdad on Saturday, a police source said, Xinhua reported.
The civilian was killed when an explosive charge planted in his car detonated in the morning while he was driving in the Tobchi neighborhood in northeast the capital, the source told Xinhua on condition of anonymity.
Another civilian was wounded by the blast, the source said.
In a separate incident, two policemen were wounded when a roadside bomb went off near their patrol in Baghdad central neighborhood of Jadriyah, the source added.
A police vehicle and several nearby civilian cars and buildings were damaged by the blast, he said.
Sporadic attacks continued in Baghdad as part of recent deterioration in security which shaped a setback to the efforts of the Iraqi government to restore normalcy in the capital after more than two months of U.S. troops' pullout from cities and towns.
