A flash flood destroys Tribhuvan Trishuli Secondary School in Nepal’s Nuwakot district, but a principal’s rapid evacuation efforts save 1,643 children, according to multiple reports. On Wednesday morning, headmaster Rajendra Dawadi receives repeated warnings from people upstream and rings the school bell to move students to higher ground minutes before floodwaters arrive. The school building and other nearby structures are later swept away.

Reports describe Dawadi, 47, acting after receiving a call from a parent saying the water was rising quickly and also communicating with bus drivers to turn back. One bus was already crossing a bridge as the flood advanced, and it reaches the far side as the bridge collapses. Students are motivated uphill by events near the river, including the janitor being swept away after attempting to lock doors. While the evacuation saves students, two school staff members die.

Across outlets, the differing angles focus on the headmaster’s heroism versus the broader disaster context. Together, the articles attribute the flash flood to a large collapse of ice and rock near the Langtang Lirung area on the Tibet border, which triggers a sudden torrent downstream. Other reporting cites Nepal’s official casualty and missing-person figures, and notes fatalities in Tibet as well.
