Officials in Pakistan say a roadside bomb struck a school bus in northwest Pakistan, killing one person and injuring four others, including two children.
Monday's blast occurred on the outskirts of Peshawar, which lies near the tribal regions of Pakistan and the Afghan border.
Police initially said the driver of the bus was killed, but later identified the dead man as a passerby. Officials say the driver, two girl students and another passerby were injured in the explosion.
Authorities says the bomb may have been intended for police patrols which frequent the area.
