Chinese authorities have suspended rescue operations at the Nepal-Tibet border due to fears of a catastrophic secondary flood, as the death toll from Wednesday's glacier collapse reached 475 in Nepal.
The initial flash flood swept through Himalayan river systems, destroying villages, roads and a vital border crossing along the Kathmandu-Lhasa route. In Nepal police confirm 475 fatalities. In neighboring Tibet three people have died and over 550 remain missing. Across the devastated region nearly 1,000 people are unaccounted for including at least 540 foreign nationals predominantly Indian tourists and pilgrims.
Despite heavy rain and treacherous terrain Nepalese Army has successfully rescued 900 injured individuals including 119 foreigners from hard-hit districts like Rasuwa and Nuwakot. Helicopters are actively dropping emergency supplies to isolated valleys while rescue teams with heavy machinery and sniffer dogs clear debris. Army spokesperson Brigadier General Rajaram Basnet described the tragedy as unprecedented in scale.
However the massive accumulation of mud and debris has now blocked the Bhotekoshi River forming a highly unstable barrier lake. Authorities warn that an estimated 3 million cubic meters of water will flow into this lake over the coming days, creating a severe risk of a dam breach by September 1.
Due to this looming threat Chinese authorities have halted ground rescues instead deploying an engineering team to conduct aerial surveys and 3D modeling of the lake. Emergency responders remain on high alert as they navigate the shrinking window to find survivors amid the risk of further devastation.
