ISLAMABAD: At least five people were killed and around 28 injured early on Wednesday when a passenger bus traveling from Rawalpindi to Karachi plunged into a ravine near Dhok Pathan in eastern Pakistan, after the driver diverted from a closed motorway due to dense fog, police said.

Poor visibility during Pakistan’s winter months frequently makes long-distance travel hazardous, prompting authorities to shut motorways and major roads during severe fog to prevent accidents. However, traffic mishaps involving both light and heavy vehicles are not uncommon during such conditions, sometimes triggering multi-vehicle pile-ups.

“A passenger bus traveling from Rawalpindi to Karachi plunged into a ravine near Dhok Pathan, killing at least five people and injuring around 28 others,” Adeel Sarfraz, a senior police officer and station house officer in the area near Chakwal, told Arab News over the phone.

“The accident occurred at around 2 a.m.,” he added. “Since the motorway was closed due to dense fog, the driver diverted the bus onto the GT [Grand Trunk] Road. However, the driver was unfamiliar with the route, and poor visibility caused by the fog led to the accident.”

Winter fog is a recurring hazard across Pakistan’s plains, particularly in Punjab and upper Sindh, where conditions can deteriorate sharply during late night and early morning hours.
