听力原文： Three car bombs killed at least 43 people and wounded 76 in a co-ordinated attack on a Baghdad bus station in the morning rush hour yesterday, ending a lull in insurgent attacks as Iraqi leaders wrangle over a new constitution. A suicide car-bomber targeting policemen detonated his vehicle outside the al-Nahda bus station in central Baghdad, the U.S. military said, and a second car exploded in the station carpark soon after. A third car bomb driven by a suicide attacker exploded near the al-Kindi Hospital as the wounded were arriving for treatment. About 15 vehicles, including three police cars, were destroyed in the attacks at the bus station, a transit point for travellers heading to the country's southern provinces. Which statement is NOT true about the car bombing in Baghdad?
