Nepal's army is racing to rescue over 100 people trapped in a hydropower tunnel after catastrophic floods devastated the country's northern border region. The rescuers have already saved 350 workers and local residents from the tunnel, but face difficult conditions due to problems locating entrances. Fears of renewed flooding have also prompted Chinese authorities to halt rescue operations across the border in Tibet, where hundreds of people are still missing. A dam upstream in Tibet has been reported to have burst, exacerbating the disaster.

Story summary
A catastrophic flash flood occurred on August 26, 2026, on the Nepal-Tibet border, causing widespread destruction and loss of life. The disaster was triggered by a collapsed glacier, which sent massive amounts of water and debris downstream, resulting in the deaths of at least 273 people and leaving over 1,300 missing. The floodwaters swept through several communities, including Syapru Besi and Timure in the mountainous district of Rasuwa, with many villages and infrastructure destroyed. Rescue teams were deployed to search for survivors, but their efforts were hindered by the remote location and challenging terrain.
The disaster also affected Tibet, where a mudslide hit the land border crossing at Gyirong Port, causing major casualties and disruptions to transportation and communication networks. Chinese President Xi Jinping ordered "all-out" efforts to search for those missing and to strengthen monitoring and early warning systems to prevent similar disasters in the future.
The Nepal Tourism Board reported that 25 Canadians were among those missing, and officials warned of a high risk of secondary collapses or landslides as rain continued in the affected area. The disaster has highlighted the issue of rapidly melting Himalayan ice and the need for better preparedness and emergency response measures in the region.
