Flooding and mudslides across Nepal and China’s Tibet region have killed at least 633 people, while nearly 3,000 others remain unaccounted for as rescue teams continue searching for survivors.

The disaster struck parts of the Himalayan region with devastating force, sending large volumes of water, mud and debris through communities and damaging roads, homes and major infrastructure.

Nepal recorded 626 deaths as of Saturday, with 2,426 people still missing. The list includes hundreds of foreign nationals, trekkers, pilgrims and workers involved in hydropower projects.

In Tibet, Chinese authorities reported seven deaths and 554 missing people. More than 1,000 stranded tourists and Chinese residents have reportedly been evacuated from affected areas.

Rescue operations have been complicated by the possibility of additional flooding. Large bodies of water formed by the accumulation of ice and mud have created fresh risks for emergency workers.

Nepali authorities warned rescuers to move to safer areas after receiving reports that another water barrier had broken on the Tibetan side of the border.

China also temporarily suspended rescue operations in the worst-hit area of Gyirong because of concerns over renewed flooding. Authorities later said the immediate danger had reduced, with state media reporting that two villagers had been rescued.

In Nepal, military teams were searching for workers trapped inside a tunnel at the Trishuli 3A hydropower project. The army said about 350 people had already been rescued from the site, while more than 100 others were still believed to be trapped.

The floods have particularly affected areas along the Trishuli River, where several hydropower projects are located. Survivors described scenes of homes, vehicles and other structures being swept away within minutes.

The disaster has also affected people travelling to Mount Kailash in Tibet, a major pilgrimage destination. Many devotees were reportedly caught along the route when the floods struck.

Authorities in India have also recovered seven bodies from rivers flowing from Nepal, with the victims believed to be among those caught in the floods.

The International Federation of Red Cross and Red Crescent Societies estimated that up to 93,000 people could have been affected by the disaster and warned that the humanitarian situation could worsen as food and water supplies become increasingly difficult to access.

Rescue agencies continue to search for missing people while facing difficult terrain, damaged infrastructure and the threat of further flooding.
