DEVIGHAT, Nepal—Rescue teams searched Thursday for hundreds of missing people along the Nepal-Tibet border after the collapse of a glacier sent a deadly wall of water and mud several stories high, tearing through communities a day earlier. At least 65 of those unaccounted for in Nepal were from the U.S. and the rest were from 30 other countries, ranging from Ukraine and the U.K. to South Africa and Japan.
Videos of the disaster showed people running before the floodwaters swallowed them up and washed out buildings and bridges. At least 273 people were killed, more than 1,300 are missing, and hundreds have been displaced across the Himalayan region.
The steep slopes and the lush valleys below the Himalayan mountain range—home to many of the world’s highest peaks and remaining glaciers—are especially vulnerable to flooding and landslides.
Hundreds of Foreigners Are Missing
According to Nepal’s Tourism Board, 517 of the missing people in the country were foreigners and 178 of them were from India.Many of the missing may have been on a pilgrimage to Mount Kailash in Tibet, a sacred site for Hindus, Buddhists, and others.
Seventy-seven people from one pilgrimage group were caught in the floods at the immigration office at the border, according to a post on X from Indian spiritual guru and the head of the Isha Foundation, Sadhguru Jaggi Vasudev.
A visibly emotional Sadhguru said in a video that the group included foreign nationals from various countries. He said that there was no official information on the whereabouts of those who were at the immigration office, including 22 U.S. nationals.
“Looking at the scale of destruction, it looks bad. The same building where we were for the immigration just a week ago, that entire building is washed away,” Sadhguru said.
Helicopters Were Deployed for Rescue Because Roads Were Damaged
The disaster has left at least 270 dead and 826 people missing in Nepal, and three dead and 558 missing in Tibet, authorities said.Nepalese officials said that dozens of bridges were destroyed and nearly 25 miles of roads were damaged, complicating search efforts.
The Nepalese army has rescued more than 100 people from flood-affected areas through helicopter operations, army spokesperson Brig. Gen. Raja Ram Basnet said. Army teams also evacuated people trapped inside facilities linked to the Trishuli hydropower project, he added.
Dozens of injured people have been transported to Kathmandu for advanced medical care.
Rescuers found bodies hundreds of miles downstream from the hardest-hit areas of Chitwan district.
Bishal Kumar Bhandari, chairman of the Nepal Red Cross Society, said they have shifted their focus from rescue to large-scale relief operations in the flood-hit districts. He said that around 1,200 people were displaced from at least three villages.
In Tibet, the mudslide left mud in the surrounding areas that was more than 5 feet deep on average, Chinese state broadcaster CCTV reported. Roads leading to the crossing were all damaged, while secondary collapses or landslides might occur as rain continued in the area, it added.
Chinese authorities warned that a barrier lake, which formed at the confluence of the Tsogyal and the Purupqiangzangbu rivers, is overflowing and may burst.
The United Nations' humanitarian chief, Tom Fletcher, announced on Thursday he has ordered the release of $2 million from the U.N.'s Central Emergency Response Fund to help with medical care, shelter and water.
Experts Say a Glacier Collapse Caused Devastating Floods
The U.S. Geological Survey first reported a magnitude 4.4 earthquake early Wednesday, about 40 miles north of Kathmandu, near the border.The USGS later updated its analysis to say the seismic event was instead a magnitude 5.2 glacier collapse that sent debris flowing downstream.
Climate experts at the Kathmandu-based International Centre for Integrated Mountain Development said an avalanche from a glacier likely caused Wednesday’s flash flood.
In an emailed statement, they said that water levels at one point on the Trishuli River rose by as much as 27 feet over half an hour.
The disaster in Nepal and Tibet is not a one-off. The increasingly unstable Himalayan ice system threatens communities, infrastructure and water supplies across one of the world’s most densely populated regions.
The region saw similar flash floods in August 2025, when a glacial lake in Tibet overflowed because of high temperatures. Nine people were killed, and critical infrastructure, including a bridge connecting Nepal and China, was damaged.
