At least 250 people are missing after an avalanche hit a village in Rasuwa district, a popular trekking area to the north of the capital Kathmandu, district governor Uddhav Bhattarai says.
Foreign tourists may be among the missing in the avalanche, which hit the village of Ghodatabela.
“This area is in a natural park, which is popular with tourists. We are trying to rescue them, but bad weather and rainfall is hampering efforts,” Mr Bhattarai said.
A powerful earthquake last Saturday with a magnitude of 7.9 set off many snowslides in the Himalayan state.
The official death toll in Nepal from the magnitude-7.8 earthquake at the weekend has risen to 5057 people, the country’s National Emergency Operation Centre says.
Another 10,915 people were injured and 454,769 have been internally displaced, it said.
