PESHAWAR: Thirteen people including women and children were killed and more than a dozen injured when an overcrowded bus carrying a wedding party fell into a ravine in northwestern Pakistan on Sunday.

The driver of the vehicle lost control while taking a sharp bend and plunged into a deep ravine at Malam Jabba, 30 kilometres (18 miles) northeast of the Swat Valley.

“Three more people died of injuries in the hospital, rising the death toll to 13,” doctor Anwar Ahmed told AFP.

He said the dead were eight women, three children and two men. Senior police official Alam Zeb confirmed the toll and said the injured were taken to hospital.

Pakistan has one of the world's worst records for fatal traffic accidents, blamed on poor roads, badly maintained vehicles and reckless driving.
