At least 17 people have been burned to death in northwest Pakistan when a gas cylinder exploded on a bus after it collided with a truck.
The bus was carrying passengers to the city of Bannu when the collision happened on a highway around 140km from Peshawar, the capital of the northwestern Khyber Pakhtunkhwa province.
"The gas cylinder installed in the bus leaked after the accident and it caught fire," said Dil Nawaz Khan, a senior government official in Karak city, where the accident happened.
"All 18 people on board were burnt and only one passenger could survive. His position is also critical."
Hospital officials said six women and children were also among the dead.
