Rescue operations continued on Saturday following a devastating flash flood that struck the Himalayan border region between Nepal and China on Wednesday, leaving hundreds dead and thousands missing. The disaster, believed to have been triggered by a glacial collapse, unleashed a torrent of water, mud, and debris that obliterated entire villages and critical infrastructure in both countries.

Officials in Nepal reported more than 670 deaths, with over 2,400 individuals still unaccounted for. Chinese authorities confirmed seven fatalities and around 550 missing persons in Tibet. The combined death toll from Nepal and Tibet has reached at least 633, with nearly 3,000 people missing. In addition, authorities in India have recovered several bodies downstream along rivers originating in Nepal, suggesting the flood’s impact may extend beyond the immediate disaster zone.

Rescue teams, including Nepal’s army and disaster response units, have intensified efforts to locate survivors and provide aid amid challenging conditions. Thick layers of mud, debris, and damaged terrain have hampered access, while ongoing heavy rain related to the monsoon season threatens to complicate operations further. Helicopter sorties resumed after brief pauses due to adverse weather, delivering relief supplies such as food, clothing, and medical care to affected communities while evacuating survivors from isolated areas.

Among the hardest-hit areas is Nepal’s Nuwakot district, where entire settlements along riverbanks were washed away. Survivors arriving at relief centers often had only the clothes they were wearing, and many face the daunting prospect of rebuilding their lives from scratch. Local residents and family members anxiously searched lists of rescued people, hoping for news of missing relatives. The disaster also affected dozens of hydropower workers and hundreds of foreign trekkers and pilgrims in the region, with Nepal’s disaster authority reporting 933 hydropower employees and 517 foreigners were still missing.

At several hydropower project sites along the Trishuli valley, rescue crews are working to free an estimated 100 individuals trapped in tunnels buried under mud and debris. Specialized teams from Nepal, India, and China have been deployed to assist in these critical efforts. Experts from Nepal’s mountain rescue organizations, experienced in high-altitude operations, have also joined the search.

Authorities have expressed concerns over the decomposition of recovered bodies, which raises potential public health risks. Nepal has ordered DNA testing to identify victims before burial, with unidentified remains to be interred at a designated cemetery in Devghat. The situation has prompted calls for specialized equipment, including forensic kits and freezer units to preserve remains.

The disaster is expected to have significant social and economic consequences for the region. Nepal’s Foreign Minister Shishir Khanal estimated the reconstruction bill could reach into the billions of dollars. Meanwhile, the trauma endured by survivors and rescuers alike remains profound, as they confront the scale of devastation inflicted by one of the worst floods in the area’s recent history.

On the Chinese side, rescue efforts in Tibet have been temporarily paused in some areas due to the risk of further flooding from newly formed glacial lakes. Authorities evacuated hundreds of tourists and residents stranded in the region while continuing search operations in less threatened zones.

As rescue teams work against the clock, the hope remains to find survivors and bring relief to tens of thousands affected by the disaster, while governments and aid organizations mobilize additional resources to aid recovery in the coming weeks.
