- Flash floods and mudslides struck the Nepal-Tibet border on Wednesday
- At least 17 people confirmed dead and nearly 400 unaccounted for
- Search operations underway for 291 tourists and local guides
- Earthquake-triggered avalanche and melted snow caused the disaster
A catastrophic flash flood and mudslide struck the border region between Nepal and Tibet, sweeping away villages, roads, and critical infrastructure. Authorities reported that at least 17 people have lost their lives and nearly 400 others remain unaccounted for following the disaster, which hit early Wednesday morning, August 26, 2026, in the Rasuwa district just north of Nepal's capital, Kathmandu.
Preliminary reports indicate that the disaster was triggered by an earthquake that struck at 08:37 local time. The tremor caused an avalanche of snow and ice to melt rapidly, sending massive volumes of water rushing down into the Bhote Koshi river, which overflowed its banks without warning and inundated downstream communities.
Search and rescue operations are currently underway on both sides of the border, with 12 individuals rescued so far. The Nepal Tourism Board stated that efforts are being made to trace the whereabouts of 291 tourists and 93 Nepali nationals, including local guides, who were known to be visiting the affected area when the flood struck.

The missing travellers include 12 British citizens, alongside Americans, Malaysians, South Africans, and Indians. Footage from the area shows roaring floodwaters destroying properties. Abhi Narayan Kaphle, a spokesperson for Nepal Police, told the BBC that all security agencies are closely cooperating in rescue efforts along the river basin.
"Our logistics company has seven container trucks there, all staffed by Nepalese employees. We have lost contact with all of them. There is no signal, so we cannot reach anyone."

Several areas downstream along the Bhote Koshi river, which flows from Tibet into Nepal, have been placed on high alert as roads, communication lines, and power supplies suffer severe disruptions. Authorities confirmed that the main highway leading to Kathmandu is currently closed. Meanwhile, Nepal's Foreign Affairs Minister Shishir Khanal informed parliament that 26 police personnel, nine armed police officers, and 44 military members are among the missing.
The rugged Himalayan terrain along the Nepal-Tibet border is exceptionally vulnerable to seismic activity and seasonal extremes. A strikingly similar disaster occurred in Rasuwa last year, when a glacial burst on the Chinese side killed 18 people. The sheer scale of the latest disaster, with hundreds missing, underscores the acute geographical vulnerabilities of communities living along the Bhote Koshi river and highlights the ongoing challenges of managing cross-border climate and geological risks.
Prime Minister Balendra Shah held an emergency meeting to assess the situation and urged residents living near vulnerable river banks to remain on high alert. He stated via social media that coordination efforts with medical teams, rescue scouts, and the Red Cross are fully underway to handle the unfolding humanitarian crisis.
