At least 14 people died after a bus carrying pilgrims veered off a highway and rolled down a steep slope in central Nepal Sunday, officials said, the latest deadly traffic accident in the Himalayan nation. 

Police said the bus carrying 32 passengers plunged 70 meters (230 feet) onto a lower stretch of the winding road in Sindhupalchowk district, around 80 kilometers north-east of the capital Kathmandu.

"We have recovered the bodies of 12 passengers from the accident," police officer Prajwal Maharjan told AFP, adding that two others had died in hospital.

Four of the dead were children, traffic police added.

Some 18 passengers who were injured were taken to hospital, with officials unclear if the bus driver was among them or had fled the scene of the crash.

The passengers were returning from a pilgrimage to Kalinchowk Bhagawati, a popular Hindu temple located at a height of almost 4,000 meters in the hills of Nepal's Dolakha district, around 140 kilometers east of Kathmandu.

The cause of the accident was not yet known, but police said reckless driving down the steep and winding road could have been a key factor.

Deadly traffic accidents are relatively common in the impoverished Himalayan nation because of poor roads, badly maintained vehicles and reckless driving. 

At least 18 passengers were killed when a bus plunged into a gorge in central Nepal last month.
