On August 26, 2026, a devastating flash flood struck the Bhote Koshi River at Rasuwagadhi along the Nepal-China border. The disaster destroyed bridges, swept away highways, and devastated border settlements in an area already vulnerable to hazardous weather conditions.
Nepal’s Ministry of Foreign Affairs said the precise cause of the flash flood had not yet been fully determined, while the government framed the disaster within the context of climate change and international responsibility. The diplomatic position referenced Loss and Damage mechanisms under the UNFCCC.
Immediate humanitarian response was already mobilizing. Nepal noted that tunnel-rescue teams from India, China, and South Korea were working alongside the Nepali Army, and UN Women reported that an estimated 43,000 women and girls faced immediate humanitarian needs including food, safe water, and protection services.
