Flash floods and landslides hit communities along the Nepal–Tibet border, killing at least 160–165 people and leaving around 900 to nearly 1,000 people unaccounted for as rescue operations continue. The disaster is described as a fast-moving surge of water, mud, and debris that sweeps through villages and along river valleys.

In Nepal, the flooding affects the Bhote Koshi and Trishuli river routes, with deaths reported across multiple districts. Nepalese police and officials say bodies have been recovered and that many of the missing include tourists, including foreign nationals. Some outlets report figures near 1,000 missing overall, while others cite lower or higher totals depending on the time of reporting and the scope of who is counted.

On the Chinese side in Tibet, state media and officials report additional deaths and a large number of people still missing, including foreigners. Multiple outlets attribute the event to a glacial collapse that produces seismic activity and a downstream debris flow rather than an earthquake. Experts and officials also warn that a lingering blockage upstream could trigger further flooding.
