A bomb struck a small bus in Baghdad on Sunday, killing six passengers and wounding 10, police said. The bus was en route from the Bab al-Sharqi area to the central commercial district of Karradah when the explosion occurred at 8:15 a.m., shattering the windows of nearby stores. The bomb was left in a bag by somebody who got off the bus, police said. Sirens wailed as police and ambulances rushed to the area, and rescue workers pulled the badly burned bodies from the charred bus, the Associated Press reported.
