Located in Khyber Pakhtunkhwa province in northwest Pakistan, the crash occurred near a tunnel.
Rescue official Rehmat Ullah stated that all the deceased and injured have been transported to a hospital in Kohat.
Footage from the scene showed images of the destroyed bus, AP reported.
Unfortunately, deadly accidents are a common occurrence in Pakistan, due to poor road infrastructure and a disregard for traffic laws. Just last Sunday, a passenger bus crashed into a pillar and fell off a bridge in Baluchistan province, resulting in a fire that killed 40 people.
