At least 10 people were killed and 22 others injured when a Pakistan Air Force van was targeted with a car bomb on the outskirts of Peshawar city in the country’s restive northwest on Wednesday, officials said.

The PAF van was headed for the local airbase when explosives planted in a car were triggered by a remote control in the Badabher area, police officials said. The powerful blast also hit a crowded bus passing the area.

Ten people were killed instantly, police officials told reporters. It could not immediately be ascertained if any PAF personnel were among the dead.
