At least 23 people were killed on Tuesday when the bus they were travelling in plunged some 300 metres down the road in a mountainous region in eastern Nepal.
The Kathmandu-bound bus had left Khotang district in the morning, and was said to be overcrowded. The vehicle rolled down the road at Barkhetar of Arkhanle in the district. The wreckage was trapped between trees, making it difficult to rescue survivors.
It took hours for the rescuers to reach the accident site because of the location. The identities of the deceased are yet to be established.
Thirty one people have been rescued alive, said police adding that the injured have been admitted to a hospital. The number of passengers aboard the bus was initially 28, but it swelled to 70 when some people boarded the vehicle mid way, The Himalayan Times reported.
Reports said an army rescue helicopter was headed to the crash site. Nepal is mostly covered with mountains and most roads are narrow. Bus accidents in the country are generally blamed on poor roads. Buses are usually overcrowded and people often travel on the roofs.
