Twenty-eight people died and 15 others were badly injured when a bus skidded off a mountain road and fell hundreds of meters (yards) into a gorge in Western Nepal on Tuesday.
Local administrator Rom Bahadur Mahat said the deadly bus accident happened in the remote and rugged Mugu district.
Mahat said the death toll could rise even more since they are still searching for bodies in the area where the bus fell.
He said the injured passengers are now being treated at a local hospital.
In the initial police investigation, the bus coming from the city of Nepalgunj was just a few kilometers (miles) short of its destination, Gamgadhi town in Mugu district, when the accident occurred.
A deeper investigation of the road accident to determine what caused the tragedy is now underway.
Sources said road accidents are common in mountainous Nepal and are often blamed on poorly maintained vehicles and highways, and narrow roads with sharp bends.
