Thirty people died on Saturday when a passenger bus plunged off a mountainous road in Nepal's western Doti district, police confirmed.
The bodies were recovered from the accident site and 12 survivors were admitted to hospital.
The bus carrying more than 40 people dropped about 300 metres off the road while traveling through dense fog.
Bus accidents, blamed on poor roads and reckless driving, are common in Nepal, with 15 people having died in a similar crash in December.
