Nepal flash flood death toll reaches 160 as hundreds missing near Tibet border

On Wednesday morning, a wall of mud and rock the size of a building collapsed into a river on the Nepal-Tibet border and came down the valley like a living thing. By Thursday, at least 160 people were confirmed dead—157 on the Nepal side, three in Tibet—and authorities on both sides were bracing for the number to climb. More than 460 tourists and travelers remained unaccounted for, swept into the debris or buried beneath it, their families waiting for news that might never come.

What happened in those first hours was captured on surveillance video from the Chinese side: a dark surge of mud and stone crashing over a multistory building, swallowing it whole, while people below scattered like insects. Buses and cars vanished. Entire villages and markets were erased. The force of it was so complete that one tour operator, Sagar Pandey, flew by helicopter over the ravaged Rasuwa area where his group had been trekking and found almost nothing recognizable. "To be honest," he said, "you would think there was no human civilisation there at all." His company had lost contact with 47 people, including 15 Australians ranging in age from 11 to 64. Pandey said he held a 1 percent hope they survived. The rest, he believed, was gone.

The missing were not only locals. Among those unaccounted for were 142 Indians, 47 Americans, 33 British nationals, 34 Australians, 24 Canadians, and citizens from South Korea, the Netherlands, Malaysia, Portugal, and South Africa. Nepal's tourism board initially reported 403 tourists and travelers missing; by Thursday that number had risen to 468. On the Tibet side, Chinese state media reported 558 people missing, including 260 foreign nationals. At least 28 Nepal police officers were also unaccounted for. The disaster had caught the border region at a moment when it was full of people moving through—trekkers, tourists, workers, families.

The immediate cause was a glacial collapse. Early reports suggested an earthquake had triggered a landslide, but the U.S. Geological Survey later clarified that what seismic stations had recorded was not an earthquake at all. The tremor—initially reported as magnitude 4.4—was actually the sound of a glacier failing. A mass of rock and ice had broken free from the mountainside and plunged into the valley below, creating a debris flow that blocked the river. The backed-up water then released downstream in a catastrophic surge. Scientists noted that climate change has been increasing the frequency and intensity of such events in the Himalayas, though the immediate trigger was geological.

Rescue operations mobilized quickly but faced the scale of the disaster. Tibet deployed nearly 800 emergency workers, 150 vehicles, sniffer dogs, and speedboats. Nepal's police worked to move families from flood-risk areas to safety while also recovering and identifying bodies in the dark. The International Federation of Red Cross and Red Crescent Societies began dispatching blankets, first aid kits, stretchers, and body bags. The United Nations said it was mobilizing supplies and personnel. Chinese leader Xi Jinping called the search and rescue effort "the most urgent task."

Survivors emerged with stories of seconds that changed everything. Keshav Prasad Baral, 68, was being treated at a small hospital after being rescued by helicopter. He had tried to grab his wife's hand when he saw the mud entering their home, tried to pull her toward the terrace, but she was swept away. "My wife is still somewhere beneath the mud," he said. "She's gone." Another survivor described clinging to a mango tree as the house where he worked disappeared into the surge.

Experts warned that the disaster was not finished. A blockage remained upstream on the Nepal-China border river, and if it gave way, a second flood could follow. The death toll of 160 was already staggering, but authorities feared it would rise as rescue teams continued to search through the mud and debris, looking for the hundreds still missing.
