Why the death toll from a deadly flood near Tibet is in dispute

On 26 August 2026, a wall of ice broke off a glacier and sent floodwaters surging across the Nepal-Tibet border. Nepal says over 900 died and 4,000 are missing. China says 16 died and 546 are missing. A Tibet advocacy group reports about 300 homes destroyed in four villages, suggesting far more deaths. Reporters cannot enter Tibet to check.
