A passenger bus plunged off a highway into a deep ravine in the mountainous Dhana Sar area of southwestern Pakistan on Friday, resulting in the death of at least 40 individuals and injuring eight others. The bus, traveling from Quetta to Peshawar, lost control early in the morning and fell around 70-80 feet into a rocky ravine near the border of Balochistan and Khyber Pakhtunkhwa provinces. According to officials, the bus was overcrowded as it carried not only its own passengers but also passengers from another broken-down vehicle. The cause of the crash is under investigation, with speeding being a likely factor. Rescue teams from both Balochistan and Khyber Pakhtunkhwa provinces are on site, facing difficulties due to the rugged terrain. Identification of the deceased is currently ongoing. Pakistan's President Asif Ali Zardari has expressed his condolences to the families of the victims and wished a speedy recovery for the injured. Road accidents in Pakistan are common due to weak traffic enforcement laws, reckless driving, poor road safety standards, and excessive speeding. In May, another tragic accident occurred in northwest Pakistan when a minibus rammed into a stationary bus along a motorway, killing 17 people and injuring five others.
