ISLAMABAD: At least 13 people were killed when a passenger van and a bus collided and caught fire in Pakistan’s central Punjab province on Monday, police said. The vehicles were consumed by flames when a gas cylinder fitted in one of the vehicles exploded in the accident in Narang Mandi city, north of Lahore. “Those killed included seven members of one family,” police spokesman Manzoor Hussain told AFP. “Four were burnt so badly that they could not be identified,” he added. A police report seen by AFP said the van was carrying members of a wedding party. It blamed the bus driver for speeding, while a rescue official said fog was also a reason for the crash. Sixteen people were taken to hospital, most of them in a critical condition. Pakistan has an appalling record of fatal traffic accidents due to poor roads, badly maintained vehicles and reckless driving.
