Three car bombs targeting military patrols exploded in Baghdad on Saturday, killing four people and wounding 16, police said. Militants detonated one car bomb alongside a joint Iraqi and U.S. military patrol in the Zayuna district of eastern Baghdad, as it passed near a police station, killing two passers-by, one of them a child, and wounding 10, Reuters reported . A second car exploded near a U.S. military convoy in the west of the capital, police said. It was not immediately clear whether there were any casualties from that blast. A car bomb also killed two civilians and wounded six when it blew up near a U.S. patrol in eastern Baghdad, police said. The explosions came a day after a series of coordinated strikes in Baghdad and nearby areas killed more than 30 people and wounded nearly 100.
