Nepal Warns Rescuers After Reported Dam Breach In Tibet
A huge flood and mudslide recently hit the border between Nepal and Tibet.
It killed 469 people, and more than 1,500 people were reported missing.
While rescue workers were searching for people, Nepal received a warning that a dam or water barrier had broken again in Tibet.
Officials worried that more water could rush downstream and create another flood.
They told rescuers, security workers and other people nearby to move to safer places.
China also stopped some rescue work because an unstable lake made from mud and debris was overflowing toward the rescue area.
Nepal’s officials said the report about a lake breach had not yet been confirmed.
Rescue teams still faced difficult conditions because mud, damaged roads and buried infrastructure blocked access.
Nepal issued a fresh warning after receiving information that a water dam had burst again on the Tibetan side.
Security personnel, rescue workers and members of the public were told to remain alert and move to safer locations.
The warning followed Wednesday’s floods and mudslides, which killed 469 people and left more than 1,500 missing in Nepal and Tibet.
China paused rescue operations after an overflow risk emerged from a debris-formed barrier lake near the Nepal-China border.
Nepali authorities said reports of a lake breach had not yet been verified, and it was unclear whether they referred to the same incident as the reported dam burst.
