A speeding, overcrowded passenger bus plunges from a highway into a rocky ravine in southwestern Pakistan early Friday, killing at least 40 people and injuring eight others, according to officials. The crash occurs in Dana Sar, a remote area near the border of Balochistan and Khyber Pakhtunkhwa provinces. Balochistan government spokesperson Shahid Rind says the bus goes out of control before falling into the ravine. Multiple reports state the vehicle is overcrowded because it carries not only its own passengers but also passengers from another bus that has broken down and is also traveling toward Peshawar. One survivor quoted by local media describes a dispute after the driver stops to pick up people from the broken-down bus; the account includes an allegation that a passenger grabbed the driver by the neck, after which the driver allegedly loses control. Rescue teams work at the scene, and officials say they identify the victims. The death toll is reported as 40 across most outlets, with one report stating at least 32 deaths.
