Authorities in Nepal are warning of possible fresh flooding and urged residents in flood-affected districts to remain on high alert after water levels rose in the Bhotekoshi River. Nepali officials said Sunday's warnings come after Chinese authorities informed them of increased water flow upstream, but residents of the flood-hit areas said they were struggling to respond to alarms that have come almost non-stop since Wednesday's catastrophic floods. The combined toll in Nepal and Tibet rose to 750 dead and over 3,000 people missing after the latest updates on Sunday. Nepal’s disaster agency said the death toll had climbed to 734 with 2,498 people missing, while Chinese authorities reported 16 deaths and 546 missing.
