Fresh flood threat follows deadly Nepal glacier collapse

The death toll from flash floods triggered by a glacial collapse in Nepal reached 469 on Aug. 28, while more than 1,500 people remained missing across Nepal and neighboring Tibet, officials said.

Nepal issued a warning on Aug. 28 to move to higher ground after a dam upstream in Tibet was reported to have burst, two days after the deadly flooding.

"Information has been received that a water dam has burst again on the Tibetan side," police said in a statement. "All security personnel, rescue workers, and the general public deployed in rescue and relief operations are requested to remain alert and immediately move to a safe location/report the incident."

Chinese authorities reported three deaths and 558 people missing in Tibet. Hundreds of foreign tourists, trekkers and pilgrims from more than 30 countries were among those unaccounted for.
