Nepal races to rescue trapped workers, as flood death toll surpasses 900

Nepal's rescue teams, aided by Chinese and Indian experts, are racing to save over 900 workers trapped in tunnels of hydropower projects blocked by debris. The floods caused by a glacier collapse on the Nepal-Tibet border have resulted in 903 deaths and 4,247 missing in Nepal, while 16 people died in China and 546 are missing. Rescue operations are challenged by a large amount of debris deposited in the tunnels.
