Nepal-Tibet Floods Kill Over 1,000; Thousands Missing

At least 1,003 people have died in devastating flash floods along the Nepal-Tibet border, with more than 4,250 individuals reported missing, according to multiple sources. The disaster struck areas including Syapru Besi and Timure in Rasuwa district on Wednesday morning, destroying villages and infrastructure project sites.

The flood has caused extensive damage to roads, bridges, power projects, and highways near the border. Rescue helicopters have been dispatched but are unable to land due to high waters. Prime Minister Balendra Shah urged residents along the Bhote Koshi River to seek higher ground and exercise caution.

District administrator Narendra Pariyar warned of potential heavy casualties but said no immediate estimates were available. The cause of the inundation remains unclear but resembles a deadly flash flood on the same river last year triggered by the draining of a supraglacial lake in Tibet. According to Reuters, it is suspected that an earthquake triggered an ice-rock avalanche on the Lhende Khola river, causing the floods.

Across the border in China's Tibet, authorities reported major casualties and missing persons in Gyirong county after a mudslide hit a land crossing. President Xi Jinping urged all-out search efforts for the missing and called for stronger monitoring to prevent secondary disasters.

The Bhote Koshi River originates in Tibet and flows into Nepal's Trishuli River before eventually reaching India as the Gandak River. According to The Guardian, at least 486 tourists are among those reported missing, including nationals from India (142), the United States (47), the United Kingdom (33), Australia (34), Canada (24), and others.

Nepali police confirmed that at least 28 Nepalese police officers are missing. Chinese state media reported three deaths on the Tibet side of the border, with nearly 800 emergency workers, 150 vehicles, sniffer dogs, and speed boats mobilized for rescue efforts according to The Guardian.

Rescue teams are working to reach more than 900 missing hydropower workers, hundreds of whom are feared trapped in the tunnels and underground areas of 12 hydropower projects in Nepal. About 500 of these workers at projects damaged by the flooding in Nepal’s Rasuwa and Nuwakot districts are thought to be trapped in tunnels built to control the flow of water.

Nepal's disaster management department said 903 people have died and 4,247 are currently considered missing. At least 85 of those missing are Americans, according to The Kathmandu Post. The U.S. State Department announced it would provide $500,000 in aid for rescue efforts in the region.

The United States Geological Survey stated that a glacial collapse triggered the floods. Climate experts at the International Centre for Integrated Mountain Development confirmed that an avalanche from a glacier likely caused the flash flood. The disaster is not a one-off, as the Lhende Khola river system has now flooded twice in just 14 months.

Nepal officials reported that the death toll continued to rise from Wednesday's floods that washed away communities in Nepal and Tibet. Around 90 Americans are among the people unaccounted for, according to the U.S. State Department. The devastating flood struck the mountainous Nepal-Tibet border region, with some of the worst damage in Nepal’s Rasuwa district.
