Nepal authorities say 65 people were on board the buses missing in a river since Friday

The two buses were on the key highway connecting Nepal’s capital to southern parts of the country when they were swept away Friday morning near Simaltal, about 120 kilometers (75 miles) west of Kathmandu.

The bodies were washed away down the Trishuli river as far as 100 kilometers (60 miles). The Chitwan District Administration Office published a list with names and details of the 65 people who were on board.

There were 38 people on one bus and 27 in another. Three people survived after being ejected from one of the buses.

Hundreds of rescuers from the police and army searched the river and downstream areas Tuesday but they have yet to find any trace of the two missing buses.

Nepal’s rivers are generally fast-flowing due to the mountainous terrain. Heavy monsoon downpours in the past few days have swollen the waterways and turned them murky brown, making it even more difficult to see the wreckage.

Monsoon season brings heavy rains to Nepal from June to September, often triggering landslides in the mountainous Himalayan country.
