A passenger bus carrying people from a small town in northern Nepal crashed on a narrow mountain road on Tuesday, killing 14 people and injuring 13 others, local authorities said.

The bus was heading to Kintang, a remote hamlet up in Nepal's rugged hills from Dhadingbeshi, the main settlement in Dhading district.

‘A total of 14 people - 10 men and four women - were killed in the accident. Another 13 people were injured,’ said Bishwa Prakash Subedi, chief district officer of Dhading.

Subedi said his office has requested a helicopter to airlift six of the injured who were in critical condition.

‘The accident occurred at around 11 am local time. The bus fell some 300 metres down the road and landed on a riverbank,’ he added.

The latest accident occurred even as a search and rescue operation was ongoing after a car crashed on Sunday, killing three people, with a former minister still missing in the swollen Trishuli river in south-central Nepal.

Around 200 security force personnel have been searching for Madhav Prasad Ghimire and his two brothers, using rafts and boats on the river, according to Deepak Shrestha, a senior police officer.

In the last three months, approximately 100 people have been killed in road accidents across Nepal.

Poorly maintained vehicles, coupled with reckless driving and bad roads, lead to a number of fatal road accidents in Nepal every year.
