Authorities say they are "very confident" workers trapped in a room at the Rasuwagadhi hydropower plant have access to food and water, as the disaster becomes Nepal's deadliest since 2015.
Quick summary
The death toll from Nepal's Aug. 26 glacier-collapse flood has risen past 1,200, with more than 4,000 people still missing, according to multiple outlets. Rescue teams are focused on reaching an underground chamber at the Rasuwagadhi hydropower plant where about 46 workers are believed trapped but possibly alive with access to food and water. Rescuers have advanced 250 meters into the tunnel before encountering a blockage. More than 630 workers at hydroelectric plants in Rasuwa and Nuwakot districts remain trapped in buildings or tunnels as of Sept. 3.
