Monsoon floods and landslides have killed at least 94 people across Nepal and India but officials fear that figure could rise sharply as rescuers search for dozens believed lost under mud and in submerged villages.
Authorities Sunday upgraded the death toll from flash flooding across landlocked Nepal to 49 as the water kept rising, forcing thousands to flee for higher ground.
"Another 17 are missing. Search and rescue works are underway but the water levels have not declined yet," said Shankar Hari Acharya, the chief of Nepal's national emergency centre.
The Red Cross estimated a higher death toll of 53, with dozens more missing and injured, and thousands of homes destroyed.
In neighbouring India, a massive landslide in the mountainous north swept two passenger buses off a hillside and into a deep gorge, killing 45 people, an official said.
The coaches had stopped for a tea break around midnight Saturday in Himachal Pradesh when tonnes of rock and mud cascaded down a mountainside.
