Flash floods caused by a glacial collapse along the Nepal-Tibet border have devastated parts of Nepal, killing at least 626 people and leaving about 3,000 missing, according to official figures as of August 29, 2026. Bodies have been recovered from eight districts.

The flood began after a glacial collapse triggered an avalanche of debris that overflowed the Bhotekoshi River, leading to downstream flooding along the Trishuli River. The glacier is located at roughly 17,000 feet (about 5,180 meters) above sea level, and the flooding extended as far as Kolpurtar, approximately 73 kilometers away.

Satellite imagery shows the scale of destruction, with buildings, bridges and other infrastructure washed away near the riverbanks. The full extent of the damage and the number of missing people may change as rescue and recovery operations continue.
