Massive flash flooding, accompanied by mud and rock, surges along the Nepal–China border region after a collapse near Gyirong Port in Tibet, according to CCTV and social media footage. The flood moves through the Bhote Koshi River area and crosses into Nepal’s Rasuwa district, destroying property and leaving residents with little time to escape.

Several outlets describe the incident as a sudden “wall” of water or a surge of muddy currents. NDTV and other reporters cite CCTV footage from the Gyirong Port area, while the Daily Mail emphasizes video showing people running as water advances. Real Clear Politics and multiple photo-gallery outlets frame the event as part of a broader Himalayan valley collapse. Mint and Times of India report that videos circulate widely and that casualties are high, with some figures reported as over 150 deaths and others still missing, as rescue and search operations continue.

Overall, sources agree on the border-region mud/rock collapse near Gyirong Port, the resulting floodwater rushing into Nepal’s Rasuwa district, and the reliance on CCTV and circulating videos to document the disaster. Differences mainly relate to whether the initial trigger is described as a flash flood or a mudslide, and to the scale of confirmed versus feared fatalities.
