A massive glacial collapse has triggered catastrophic flash floods across the Himalayan border region of Nepal and Tibet, killing at least 165 people, with local officials warning that the death toll is expected to rise. The disaster has left more than 1,000 people unaccounted for, including hundreds of foreign tourists, according to the latest official figures.

The US Geological Survey said the floods were caused by a large-scale glacial collapse in the high mountain region, a phenomenon increasingly linked to climate-driven instability in glacial systems. The surge of water and debris swept through valleys and settlements, destroying infrastructure and homes in areas popular with trekkers and pilgrims.

Officials in Nepal reported 826 people missing, among them 579 tourists from around two dozen countries, including India, the United States, Australia, Britain and Canada. Chinese state media said 558 people were missing in Tibet's Gyirong county. It was not immediately clear whether the two sets of figures were separate or whether some individuals had been counted twice.

Rescue operations are under way, with Nepali army units deployed to search for survivors in the worst-affected areas. Footage from the scene showed soldiers pulling people from debris and mud as they worked through difficult terrain. The Rasuwa region, a popular starting point for Himalayan expeditions, has been particularly badly hit, with dozens of foreign nationals among those unaccounted for.

At least 33 British citizens are among the missing, according to updated figures, with 341 foreign nationals listed as unaccounted for in Nepal. The British government has said it is providing consular support to families affected by the disaster and is liaising with Nepali authorities on the ground.

The floods have raised fresh concerns about the vulnerability of mountain communities to glacial lake outbursts and related events. Scientists have repeatedly warned that rising temperatures are accelerating glacial melt and increasing the risk of sudden collapses in the Himalayas, one of the most glacier-dense regions on Earth.

Local authorities have appealed for international assistance, saying that the scale of destruction has overwhelmed regional response capabilities. Search teams are focusing on riverbanks and downstream areas where debris has settled, while medical teams have been dispatched to temporary shelters for survivors.

The full extent of the damage is still being assessed, with many remote villages cut off by damaged roads and bridges. Officials have cautioned that the number of confirmed deaths is likely to climb as rescue teams reach isolated areas and as the list of missing persons is cross-checked against survivor registries.
