A glacier collapse on August 26 triggered floods that killed 939 people and left 3,925 missing along the Nepal-Tibet border, including more than 600 workers trapped in tunnels at the Trishuli-3A hydropower site. Rescue teams led by Chinese and Nepalese military personnel with international experts have rescued 279 individuals and used explosives to access the tunnels. Sources report consistent casualty figures but differ on precise missing counts and include an anomalous rescue date of August 29, 2026.
