Nepal is facing a catastrophic flash-flood and landslide disaster along the Nepal–Tibet (China) border after a huge ice-and-rock/glacial collapse sent a massive surge of water, mud and debris down the Lhende/Bhote Koshi river system.

Latest situation:
Death toll: around 1,380+ people have been reported dead, with figures still being updated.
Missing: more than 5,000 people remain unaccounted for in Nepal and the adjoining Tibet region.
Hydropower workers: rescuers are concentrating on workers believed to be trapped in tunnels at several hydropower projects; officials estimate that 121 workers may be trapped in tunnel networks.
Rescue operations: Nepalese forces, along with international teams, continue searching damaged hydropower sites and other areas. Several people have remarkably been rescued alive from tunnels and buried structures in recent days.
Infrastructure: roads, bridges, homes, hydropower facilities and the important Gyirong–Nepal border crossing have suffered massive destruction.
National mourning: Nepal observed a national day of mourning on 7 September for the victims.
Fresh danger: authorities are also monitoring new landslide-related flood risks, including a partially blocked river in Darchula.
The Government of Nepal's official 7 September situation report confirms that search, rescue and relief operations remain active on the 13th day after the disaster.
Important: Some social-media videos circulating about the disaster are AI-generated or falsely described. AFP has specifically debunked a viral video claiming a dam collapse caused the flood; the disaster was associated with a high-altitude glacial/rock collapse.
International assistance: India, China and other countries are supporting Nepal's rescue and relief operations; more than $42+ million in aid has reportedly been pledged.
Ministry of Foreign Affairs, Total: 30 countries.
In addition, assistance/support has come from the European Union, Asian Development Bank, World Bank, United Nations and its specialised agencies, among others.
The EU has also delivered an 82-tonne humanitarian air-bridge shipment and provided an additional €500,000 for the response.
Rescue operations have resumed after being temporarily interrupted because of the danger from a newly formed lake and additional landslide/avalanche activity.
Nepal has requested specialist technical assistance, including tunnel-rescue expertise. India has sent a specialised rescue team, while China is also assisting with rescue and monitoring.
The disaster has badly damaged roads, bridges, hydropower projects and settlements. Nepal's Finance Minister estimates reconstruction could cost around $4–5 billion.

What happened?
The disaster occurred around the Bhote Koshi/Lhende Khola river system in Rasuwa, close to the China border. Preliminary satellite analysis indicates that an ice-and-rock landslide occurred upstream, apparently blocking the river and creating a temporary debris-filled lake. When the blockage failed, a powerful surge rushed downstream. The latest evidence points to a glacial/ice-and-rock collapse and resulting debris flow, rather than an ordinary monsoon flood. The material entered the Himalayan river system and generated an extremely destructive flash flood.
There has also been discussion of whether an earthquake contributed to the landslide, but the precise triggering mechanism is still being investigated.
Worst-affected areas
The Rasuwa district, particularly Syapru Besi and Timure, has suffered severe destruction. Floodwaters also affected downstream areas along the Trishuli River, including Nuwakot, Dhading, Gorkha and Chitwan. Authorities warned people living near major rivers to move to safer locations.
Infrastructure destroyed
The extremely fast-moving, debris-filled water damaged or destroyed:
Houses and villages, Roads and bridges, Vehicles, Electricity and power infrastructure, Hydropower project facilities, Border and customs infrastructure, Communications and transportation links
The destruction has made access to several affected areas extremely difficult.
Rescue operation
The Nepal Army, Armed Police Force and Nepal Police have been deployed for search-and-rescue operations. Helicopters and other emergency resources are being used, although damaged roads, high river levels and difficult Himalayan terrain are complicating operations.
Impact in Tibet
The disaster also severely affected Gyirong County in Tibet, on the Chinese side of the border. Chinese authorities reported deaths and hundreds missing after a mudslide hit the area, damaging roads, communications and power infrastructure.
Important warning
Authorities are urging residents and travelers to stay away from the Bhote Koshi, Trishuli and other swollen rivers because additional flooding and landslides remain possible. The situation is still developing, so the death and missing-person figures should be treated as provisional.
Nepal is facing one of its most serious sudden flood disasters of 2026. A suspected ice-and-rock landslide and subsequent river blockage produced a devastating flash flood near the Tibet border, Reuters reports at least 584 deaths, with hundreds still missing, including many foreign travelers.
