A devastating flash flood and mudslide struck the Nepal-Tibet border on August 26, 2026, killing at least 22 people in Nepal and causing major casualties at Tibet's Gyirong Port. The disaster, triggered by a 4.4-magnitude earthquake and a subsequent ice-rock avalanche that blocked the Lhende Khola River, left 384 tourists and dozens of local workers missing. The Nepalese military deployed helicopters to rescue survivors, while India, China, the US, and South Korea coordinated emergency relief efforts.
