Flash floods and mudslides hit communities along the Nepal–Tibet border, killing at least 160 people and leaving more than 1,000 others missing as rescue teams search for survivors. The disaster strikes soon after a high-altitude geophysical event earlier on Wednesday, sweeping away homes and vehicles and engulfing areas along river valleys.

Across the reporting, the death toll and missing figures vary by source and time of compilation, with several outlets citing about 160–168 deaths and hundreds to nearly 1,500 missing. Multiple reports describe people—including tourists and other travellers—being unaccounted for, with Nepal and Chinese authorities giving separate counts for their sides of the border. CBS and other outlets describe the event as a glacial-collapse-triggered flood and mud flow; the US Geological Survey concludes the initial reports of an earthquake are instead consistent with a glacial collapse and downstream debris impacts.

Authorities warn about possible continuing hazards, including the risk of a second flood if a river blockage persists upstream. Nepal and China mobilise rescue operations, and officials say international routes for travel in the Himalayas—such as areas connecting to Tibet—are affected, alongside trekking and pilgrimage areas.
