Two car bombs targeted Sunday morning commuters in Baghdad, killing at least 18 people.
The blasts came a day after a senior US official wrapped up a three-day visit to Iraq to meet with top political leaders to discuss the security crisis in the vast Sunni-dominated province of Anbar.
The deadliest blast occurred at a bustling bus station in central Baghdad when an explosives-laden car exploded outside, killing at least nine people and injuring 16. Thousands of people use the bus station every day or pass through the area.
Another parked car bomb targeted a gathering of buses and taxis in Baghdad's northern Hurriyah neighborhood, killing four civilians and wounding 12.
