Himalayan Flash Floods Leave Nearly 1,500 Missing Across Nepal and Tibet

A catastrophic flash flood triggered by a glacial collapse in the Himalayas has left nearly 1,500 people missing across Nepal and China's Tibet region, authorities reported on Thursday. The disaster, which struck on Wednesday, unleashed a wall of mud and rock into a river, sending torrents of debris through towns and valleys popular with trekkers and pilgrims.

In Nepal, police confirmed at least 165 deaths, with the toll expected to rise significantly as search operations resume. Among the 826 people reported missing in the country, nearly 600 are foreigners from more than two dozen nations, including 177 from India, 63 from the United States, 34 from Australia, and 33 from Britain.

Across the border in Tibet's Gyirong county, Chinese state media reported 558 people missing, including 260 foreign nationals. Verified videos showed the crushing force of water and debris sweeping away people at a border crossing, while homes, roads, and power projects were destroyed further downstream.

Survivors described harrowing escapes. One 68-year-old man, treated in a hospital, recounted how the mudflow entered his home and swept away his wife despite his efforts to pull her to safety. Another survivor clung to a mango tree as the house he was working in vanished.

Helicopters have begun delivering tents, food, and emergency supplies to the hardest-hit areas, with more than 5,000 army and police personnel mobilised for rescue efforts. The U.S. Geological Survey indicated that the event was triggered by the collapse of glacial rock and ice, rather than an earthquake as initially suspected.

Chinese authorities have also flagged risks from a still-dammed lake upstream, which could complicate rescue operations. Many of the victims were on a pilgrimage to the sacred Mount Kailash and Lake Mansarovar, revered by Hindus and Buddhists.

International response has been swift, with the U.S. providing $500,000 in assistance, and the U.N. sending supplies and personnel. A tourism operator reported that 15 Indian-Australians on a pilgrimage tour with his company were missing, describing the zone as completely flattened. "Everything is just flat," he said after a helicopter flyover. "Anyone in the hotel, the restaurant, or the car, I believe that everybody is gone."
