(CNN) -- At least 29 people died after a passenger bus plunged down a cliff in the remote mountains of western Nepal, police said Tuesday.
The accident occurred Monday night on a gravel road in the Kalikot district, about 280 miles (450 kilometers) west of Kathmandu, authorities said.
"The bus driver seems to have lost control at a hairpin bend and the bus fell about 400 meters," said police inspector Barun Bahadur Singh.
Eleven people were rescued and were being treated in a local hospital, Singh said.
In the mountains of Nepal bus accidents are frequent because of poor roads, old buses, overcrowding and inexperienced drivers.
On Sunday, 13 people were killed in another bus accident in Gulmi district in western Nepal.
