Nepal Searches for 933 Hydropower Workers Missing After Floods
A huge flood hit parts of Nepal on August 26.
The flood damaged homes, roads, bridges and hydropower projects.
Officials say 933 workers and employees have not been heard from since the flood.
More than 600 may still be inside underground tunnels filled with mud and water.
Some other missing people may have been carried away by rivers.
Rescuers have already saved 279 people from tunnels.
Army engineers are digging and carefully blasting rocks to reach people at one project.
Teams from India and China are helping with the rescue.
Survivors said they escaped by climbing hills, walking through forests or holding onto ladders in tunnels.
Nepalese authorities are tracing 933 hydropower workers and employees who have been out of contact since August 26.
More than 600 people are believed to be stranded in silt-filled tunnels, while others may have been swept downstream.
Rescuers have saved 279 people, including 254 from Upper Trishuli-1 and 18 from Langtang Khola.
Nepali Army engineers are using heavy machinery, ropes, trained dogs and controlled blasting at Upper Trishuli-3A in Nuwakot.
Teams from India and China are assisting Nepal as survivors describe escapes through forests, hills and flooded tunnels.

Official and Company Estimates
Reported Rescue Uncertainty
Scale of the missing-worker crisis
Official and Company Estimates
NDRRMA reported 933 people missing from hydropower projects and more than 600 believed stranded in tunnels.
Reported Rescue Uncertainty
The Independent Power Producers’ Association, Nepal, cited at least 900 workers unaccounted for and about 500 believed trapped, while another report estimated 933 people still trapped; the differing figures reflect uncertainty about workers’ locations.
Prospects for survivors
Official and Company Estimates
Rescue teams and an outside geoscientist said some trapped workers might have access to oxygen, and operations continued to reach them.
Reported Rescue Uncertainty
Officials and power-sector representatives warned that the chances of finding survivors were diminishing because workers may lack food, water or air; four bodies were reported recovered from three mud-filled tunnels.
