Three passengers managed to escape before the vehicles crashed into the Trishuli river in Chitwan district.
At least 63 people were missing in Nepal on Friday after a landslide triggered by heavy monsoon rains swept two buses off a highway and into a river, authorities said.
Dozens of search and rescue personnel were combing the site for survivors of the accident in the central district of Chitwan, district official Khimananda Bhusal said.
Bhusal said that the buses were carrying at least 66 people between them but three passengers had been able to escape before they crashed into the Trishuli river and were now being treated in hospital.
“We are not sure of the total number because the buses could have picked up others on the road,” he said.
“The river has swollen and no one else has been found yet.
