Nepal Flash Flood Triggers Warning Questions After Tibetan Deluge
A very large flood came from the Tibet side into Nepal’s Bhote Koshi River.
It hit places near the Nepal-China border, including Timure and Syabrubesi.
Many homes, roads, bridges and other buildings were damaged.
Early reports said 16 people had died and hundreds were missing.
Some tourists and people from other countries were also feared missing.
Nepali officials said they learned about the flood from local reports before receiving information from Chinese authorities later in the day.
A Nepali journalist criticized China for not giving an earlier warning.
China’s side of the border was also hit, and officials there ordered rescue and stronger warning systems.
A flash flood entered Nepal’s Bhote Koshi River from Tibet on August 26, affecting Rasuwa, Dhading and Nuwakot districts.
Early reports said at least 16 people died in Nepal, while hundreds were missing, including tourists and foreign nationals.
The flooding destroyed homes, vehicles, roads, bridges, customs facilities and hydropower infrastructure near the border.

Nepali authorities launched alerts, rescues and evacuations, while Bihar in India raised its own alert after water levels increased in the Gandak River.
