A bus veered into a ravine in Pakistan's far north early on Friday, a local government spokesman said, killing 20 passengers, while 21 injured were rescued and taken to hospital.
The bus was headed to the mountainous northern area of Gilgit-Baltistan from the garrison city of Rawalpindi in Pakistan's eastern province of Punjab, when the accident happened in the early hours.
"The bus was passing through Diamer district in Gilgit-Baltistan when it fell into a deep ravine," Faizullah Firaq, a spokesman for local government authorities in the area, told Reuters, adding that 21 people were injured.
The government immediately launched a rescue operation to evacuate all the injured, who were taken to hospital, he added.
