Chinese authorities disclosed Sunday that 261 foreign nationals from 23 countries are among the 546 people missing in Tibet after last week's devastating flood, offering their most detailed accounting yet. The largest groups include 104 Nepalis, 49 Indians, 33 Latvians, 18 Americans, and 15 British citizens, according to Xinhua. The death toll in Tibet has reached 16, while Nepal confirmed 734 dead with nearly 2,500 missing.

The disaster struck Wednesday along the Nepal-Tibet border when a glacier on Langtang Lirung broke off at 17,000 feet, triggering a massive landslide that traveled 13 miles to Gyirong Port, destroying 27 buildings across 172 acres. Chinese rescue workers arrived Friday, over 50 hours later, hampered by destroyed roads and rainfall. China has dispatched helicopters, rescuing 94 Chinese nationals, and sent tunnel experts to a damaged Nepalese hydropower station.

Xi Jinping pledged assistance to Nepal. Tibet remains tightly controlled, with Chinese social media censoring non-state content about the disaster.
