A bus veered off a Nepal road and plunged into a river, killing at least nine people and injuring 18 more in the mountainous nation's second road disaster in as many days, police said.
The bus rolled some 100 metres from the road and plunged in the Trishuli river about 50 miles west of Katmandu, the capital.
Six bodies were pulled from the wreckage and three people died on the way to the hospital.
Rescuers continued searching the swollen river for passengers. It was not clear how many people had been on the bus.
Police are investigating the cause.
At least 39 people were killed on Sunday in another bus accident in Nepal, where roads and vehicles are often poorly maintained.
