At least 17 people have been killed in a bus bombing near the north-western Pakistani city of Peshawar, officials say.
The vehicle was carrying government employees back home in the Gulbela area, some 15km north-east of the city.
More than 70 passengers were on board, police said.
Peshawar, the main city of Khyber Pakhtunkhwa province, has been hit by numerous bomb and gun attacks blamed on Taliban insurgents in recent years.
Initial reports say the bomb was planted in the back of the bus.
