Seventeen bodies have been recovered after a landslide swept away several houses in the western Nepalese district of Kaski on Friday, officials say.
The Chief District Officer in Kaski, Badri Nath Ghimire, told the BBC that rescue teams have reached the area and their work is continuing.
He said up to 15 more people had been reported missing.
Mr Ghimire said heavy rain triggered the landslide, and that the hilly terrain made the rescue effort harder.
Reports say local villagers, Red Cross officials, political party activists and Maoist rebels are also helping in the search and rescue operation.
But officials say that the chances of finding survivors are slim.
