For the second time in just over a year, a sudden surge from Tibet has torn through the same stretch of river — but this time, hundreds of foreign tourists are among the missing.
New Delhi, August 26, 2026 — A massive flash flood swept down the Bhotekoshi River into Nepal’s Rasuwa district early Wednesday morning, devastating settlements near the China border and triggering a nationwide emergency response, with hundreds of people — including nearly 300 foreign tourists — still unaccounted for hours after the water hit.
The Himalayan Times reported that a huge and sudden flood entered the Bhote Koshi River from the Chinese side on Wednesday morning, causing major damage in parts of Rasuwa and prompting authorities to issue high-alert warnings downstream as far as Muglin. The outlet quoted an unnamed official describing the scale bluntly: “The flood is unprecedented and huge,” noting damage in Gosaikunda Rural Municipality-2, Timure, and Ward No. 5, Syabrubesi.
The Kathmandu Post reported the flood struck early Wednesday, damaging settlements and infrastructure along the river, with Chameli Gurung, deputy chair of Uttargaya Rural Municipality, saying around a dozen settlements had been affected, including Syaphrubesi, Betrawati, Mailung, Salletar, Shantibazar, Pairebesi, Khalti Basti, Sole, Trishuli and Battar. Abi Narayan Kafle, spokesperson for Nepal Police, said the Area Police Office in Timure, the police post in Syaphrubesi, and the police post at Rasuwagadhi had also been damaged.
Rasuwa’s Chief District Officer, Narendra Pariyar, described the confusion around the flood’s cause in remarks carried by regional wire reports: “It has not rained here. The sun is shining here. It is not clear whether the glacier burst upstream or what happened.” He added that there could be “heavy casualties or loss of property,” while cautioning he could not confirm details yet.
Nepal’s government moved quickly at the highest levels. Prime Minister Balendra Shah called an emergency meeting to discuss the flooding. The government mobilized the Nepali Army, Armed Police Force, and Nepal Police for rescue and relief operations, with additional personnel dispatched from other districts. Two Nepali Army helicopters were deployed for search and rescue, though water levels initially left some of the worst-hit areas inaccessible from the air.
The National Disaster Risk Reduction and Management Authority (NDRRMA) has been activated nationally, with the Home Ministry holding an emergency meeting and medical teams, Scouts, and the Red Cross asked to coordinate relief efforts.
Authorities extended their warnings well beyond the immediate disaster zone. The NDRRMA issued a special request urging residents in Rasuwa, Nuwakot, Dhading, Gorkha, and Chitwan to remain vigilant and move to safe locations, as rising water in the Bhotekoshi
threatened to raise levels in the Trishuli River downstream.
Hundreds Missing, Including Foreign Tourists
The scale of those unaccounted for has drawn international attention to what began as a localized disaster. Officials said 384 tourists — including 291 from countries such as India, the United States, the United Kingdom, and Malaysia — were reported missing as a result of the flood; Nepal’s tourism board said over 100 of the missing were Indian nationals. Most of the missing Indian tourists are reportedly on their ways to the Kailash Mansarovar Yatra. They were waiting to cross over into Tibet.
Sixty employees of the under-construction Langtang Khola Hydroelectric Project in Rasuwa municipality were also reported missing, with Nepali state media reporting the workers had been carrying out concrete construction inside a tunnel when the flood struck, causing severe damage to the project site.
Nepal government spokesperson Sasmit Pokharel confirmed the country had sought outside help, saying: “We have asked both India and China to help us with the rescue efforts.”
A Painful Repeat
For residents of Rasuwa, Wednesday’s disaster carries a grim familiarity. The Kathmandu Post noted the flooding comes just over a year after a devastating flash flood struck the same area: on July 8, 2025, a flood originating in Tibet’s Lhende river surged into the Bhotekoshi, killing at least nine people and leaving 19 missing, sweeping away the Miteri Bridge linking Nepal and China, damaging the Rasuwagadhi dry port and hydropower infrastructure, and severely damaging the road between Syabrubesi and Rasuwagadhi.
That prior disaster was eventually linked to intense rainfall on the Chinese side of the border. What triggered Wednesday’s flood remains officially unconfirmed — local officials have pointed to the possibility of a glacial lake outburst or an upstream glacier event, but as of this report, no Nepali authority had issued a definitive explanation.
With water levels still elevated and rescue helicopters facing access constraints in the hardest-hit areas, Nepal’s government has yet to release a confirmed toll of deaths, injuries, or property damage. The Kathmandu Post reported that preliminary information from local officials, residents, and security agencies — along with photographs and videos from the affected areas — points to significant destruction, even as the full picture remains unclear. For a district that endured nearly the same disaster scenario a year ago, the immediate priority for Nepali authorities is locating hundreds of missing people before water levels or further upstream activity complicate the search.
