Nepali rescuers on Monday continued searching for hydropower workers believed trapped in tunnels after devastating floods, as the search entered a sixth day. Three bodies were pulled from two tunnels, which were found full of mud. Officials have not made contact with any of the feared trapped workers, but the government said more than 100 workers may still be alive inside multiple tunnels. The National Disaster Risk Reduction and Management Authority said 933 hydropower workers have been missing since Wednesday, when a wall of mud and debris swept through the area. At the Upper Trishuli 3A site, rescuers broke through into the upper part of a mud-filled tunnel, pumped air inside, and were using drilling and excavator machines to dig down.
