Flash Floods Hit Nepal and Tibet Border Leaving Hundreds Missing

A catastrophic flash flood swept through the Himalayan border region between Nepal and Tibet at approximately 8:30 a.m. local time on Wednesday, leaving at least 17 people dead and nearly 400 others missing across multiple settlements.

The deluge severely damaged northern Nepal's Rasuwa district and Tibet's Gyirong county. Authorities reported that 384 individuals remain unaccounted for, comprising 291 international tourists and 93 Nepali citizens. Among the missing foreigners are travelers from the United States, India, Australia, the United Kingdom, Malaysia, South Africa, and the Netherlands. Three American citizens missing in the area were confirmed to be traveling with the agency Fishtail Tours and Travel.

Infrastructure across the region suffered immense destruction. Verified video footage located near Trishuli Bazaar in Nuwakot District captured the Trishuli River suddenly swelling with thick sediment, tearing a bridge off its foundations and collapsing multi-story buildings along the riverbank. In addition, 60 construction personnel working inside a tunnel at the 20 MW Langtang Khola Hydroelectric Project in Rasuwa municipality were reported missing after floodwaters struck the facility.

Official assessments indicate the disaster was initiated by a seismic event upstream. Officials from the United States Geological Survey recorded a magnitude 4.4 earthquake in the region at the time of the sudden inundation.

"An earthquake occurred at 8:37 a.m. today, and due to it, a large landslide occurred, blocking the river, which appears to have caused the flood," said Shishir Khanal, Nepal's Foreign Minister.

Experts at the International Centre for Integrated Mountain Development noted that the peak surge occurred along the Lhende Khola River, a tributary of the Bhote Koshi River, likely triggered by a glacial avalanche.

Emergency teams, military personnel, and volunteers have deployed to conduct search and rescue operations, though high water levels have constrained aerial efforts. The Red Cross activated response teams and mobilized relief supplies to assist displaced residents.

"People along the river are advised to exercise extra caution and remain alert," said Balendra Shah, Prime Minister of Nepal.

Military units attempting to reach affected northern zones such as Syapru Besi and Timure reported that aerial landings remain impossible until floodwaters recede. Operations are continuing via air transport where conditions permit.

Across the border, Chinese authorities reported significant damage and casualties in Tibet's Gyirong county. Government agencies launched disaster relief protocols, dispatching emergency supplies including thermal gear, bedding, and temporary shelters to the impacted zones.
