A heart-stopping CCTV video circulating online captures the exact moment a massive wall of mud, water, and debris slammed into a busy border checkpoint along the China-Nepal frontier Wednesday, turning a routine morning into a scene of pure chaos and destruction.
The footage, timestamped around 10:59 a.m. local time at Gyirong Port in Tibet, starts with people walking, vehicles parked, and normal activity at the trade hub. Within seconds, a roaring torrent of brown sludge and rocks barrels down the valley, swallowing buildings, trucks, and anyone in its path. Dust and debris explode into the air as the camera is partially obscured by the force of the surge. Viewers can see individuals scrambling in a desperate attempt to escape before the wave hits.
Authorities on both sides of the border are reporting a devastating human toll. At least 8 to 17 people have been confirmed dead in Nepal, with the number expected to rise sharply. Nearly 400 travelers are missing, including 291 foreign tourists, among them Indians, Britons, Americans, Malaysians, and others. Dozens of Nepali police, armed forces, and military personnel are also unaccounted for. Chinese state media described “major casualties and missing persons” at the Gyirong Port itself after the mudslide crossed from the Nepali side.
Nepalese officials say a morning earthquake triggered an avalanche of ice, rock, and melted snow that poured into the Bhote Koshi River, unleashing the flash floods and mudslides that tore through Rasuwa district north of Kathmandu and barreled across the border. Entire villages were washed away. Roads, bridges (including the Friendship Bridge), and critical hydropower projects were destroyed, knocking out more than 12% of Nepal’s national electricity capacity. Helicopters have been grounded in some areas because water levels remain too high for safe landings.
Chinese President Xi Jinping has ordered “all-out” search-and-rescue efforts, calling the situation urgent and demanding stronger early-warning systems to prevent further disasters. Rescue teams with heavy machinery and drones have been deployed on the Tibetan side, while Nepal’s army and police continue searching the swollen river valleys.
The viral video has left many stunned. One local witness described watching the flood “sweep away eight or nine trucks, along with houses and people.” Downstream communities in Nepal have been ordered to higher ground as officials warn of the risk of secondary floods if debris continues to block the river.
This remote Himalayan border region has seen deadly flooding before, but the speed and scale of Wednesday’s disaster, captured in real time on security cameras, has underscored just how quickly nature can erase lives and infrastructure in these steep mountain valleys. Search operations continue as families around the world wait for word on the hundreds still missing.
