Death toll from mudslides, flooding at Nepal-China border climbs past 670; nearly 3,000 missing

The death toll from the devastating floods and mudslides along the Nepal-China border has risen to at least 676 people, as rescue operations stall amid poor weather.

After Nepali authorities updated their figures Saturday, the combined toll in Nepal and Tibet rose to 676 dead and nearly 3,000 people missing, according to The Associated Press.

Chinese authorities have reported seven deaths and more than 550 missing, while Nepal’s disaster agency said the death toll had climbed to 669 with 2,426 people missing.

Experts believe Wednesday's mudslides and flash flooding across Nepal and China's Tibet region were caused by a large chunk of ice breaking off a glacier and falling into the Lhende Khola River.

"Search and rescue operations have been temporarily halted because it is raining, and the weather is foggy," Narendra Pariyar, a top official for Nepal's Rasuwa district, told Reuters.
