An initial investigation into a fatal bus crash in Pakistan has found “traces of explosives” at the site, raising the possibility the incident was a terror attack.

A bus carrying dozens of construction workers fell into a ravine in the district of Kohistan in Khyber Pakhtunkhwa province on Wednesday after what authorities said was a gas leak in the vehicle that caused an explosion.
