A minibus exploded near a market district Monday in Baghdad, killing at least six people and wounding 31, officials said. Black smoke rose into the air after the blast struck a transit point near Tayaran Square at about 1 pm, police and hospital officials said. The minibus was one of several waiting for passengers heading to predominantly Shiite areas in eastern Baghdad. Several nearby cars and kiosks also were damaged, the officials said. The bombing came hours after the expiration of a vehicle ban that had been imposed in the capital on Sunday ahead of Iraq's soccer final against Saudi Arabia. Iraq won the championship and tens of thousands of Iraqis poured into the streets for largely peaceful celebrations.
