At least nine people have been killed and hundreds of tourists are missing after a massive landslide triggered catastrophic flooding near Nepal’s Himalayan border with China’s Tibet region.

Videos verified by Reuters showed a wall of mud, rocks and water crashing through the area, sweeping away buildings, vehicles and people. Authorities on both sides said the full scale of the disaster remained unclear and the death toll could rise.

Hundreds missing after disaster

Nepal’s tourism authority said at least 384 travellers were reported missing, including 105 Indians, 93 Nepalis, three U.S. citizens and 12 British nationals.

South Korea’s Yonhap news agency separately reported that around eight South Korean nationals were also unaccounted for in Nepal.

The disaster struck near the towns of Timure and Syapru Besi in Nepal’s Rasuwa district, where homes, roads and hydropower projects were damaged or destroyed.

Nepali officials said rescue efforts were being hampered by difficult terrain and strong river flows, preventing helicopters from landing in some affected areas.

Possible earthquake linked to landslide

Nepal’s Foreign Minister Shisir Khanal told parliament that initial reports suggested an earthquake may have triggered an avalanche that led to the flooding.

The German Research Centre for Geosciences said a magnitude 4.4 earthquake was recorded around seven minutes before the time shown on security footage capturing the disaster.

However, experts said the exact cause remained unconfirmed. Qianggong Zhang, head of climate and environmental risks at the International Centre for Integrated Mountain Development in Kathmandu, said an ice-rock avalanche into the Lhende Khola river may have triggered the event.

He warned that a second flood could occur because debris continued to block parts of the river upstream.

China launches rescue efforts

Chinese state media reported that the landslide affected the Gyirong border crossing in Tibet, cutting roads, communications and power supplies across the area.

China deployed at least 574 rescuers to the affected border region, according to state broadcaster CCTV.

A rescuer said teams faced major challenges because around 1.5 metres of sediment had blocked access routes. Chinese President Xi Jinping called for intensified search operations and improved early warning systems to prevent further disasters.

Major damage to infrastructure

Nepal’s Energy Ministry said 430 megawatts of power supply had been affected, mainly due to damage to hydropower projects. The disruption represents more than 12 per cent of the country’s total hydropower capacity.

Local officials warned residents living along the Bhote Koshi river to move to safer areas.

“There could be heavy casualties or loss of property,” said Rasuwa district administrator Narendra Pariyar, urging people to remain alert.

Health worker Tula Bahadur BK described widespread destruction in the area, saying settlements near the river had been completely swept away and five of his relatives were missing.

India offers humanitarian support

Indian Prime Minister Narendra Modi said New Delhi was ready to provide all possible humanitarian assistance, with teams from India and Nepal coordinating rescue and relief efforts.

The Bhote Koshi river, which originates in Tibet, flows into Nepal’s Trishuli river before eventually entering India as the Gandak river.

The region has seen similar disasters before. Last year, flooding in the Bhote Koshi river killed nine people and left 24 missing. It also destroyed a bridge linking Nepal and China and disrupted trade for months.
