Rescue teams in Nepal continue to search water-logged hydropower tunnels in the country’s north, where hundreds of workers remain unaccounted for seven days after a flash flood devastated areas near the border with China.

The death toll has risen to 1,003, Nepal’s National Disaster Risk Reduction and Management Authority (NDRRMA) said on Tuesday afternoon.

Nearly 4,000 people remain unaccounted for, the country’s Foreign Ministry said, adding about 590 foreign nationals from 39 countries are among them. Some 11,800 have been rescued.

As the authorities try to bring relief and supplies to survivors , rescue teams are racing to locate the hundreds believed trapped in the 12-13 tunnels of the many hydroelectric projects dotting the Trishuli river corridor.

The NDRRMA has listed 639 people associated with the hydropower projects as missing. But the authorities have not been able to establish how many of those could be inside the tunnels or may have been swept away.

At the Upper Trishuli-3A Hydropower Project, where rescue teams had located and drilled into the tunnel’s head on Monday, they were still pumping in air and draining water to enable entry. Excavators and rock breakers are clearing access routes to the 4 km-long tunnel, where between 30 and 40 people are believed to be in the underground powerhouse, the Kathmandu Post reported.

The Nepalese Army said 279 people had been rescued alive from hydropower projects immediately after the floods, including 221 from Upper Trishuli-3A and 33 from Upper Trishuli-1. More than 21,000 Nepalese security personnel are involved in the search, evacuation, and relief work. The NDRRMA said 37 trucks and 37 utility vehicles carrying food and relief materials had been dispatched to affected areas, with supplies also delivered on nine helicopter flights.

Nepal has requested equipment including LiDAR, temporary bridge units, freezers, DNA testing kits, and high-capacity drones to support rescue and relief operations.

The Foreign Ministry said it is helping families of missing foreign nationals obtain information about their loved ones and, where needed, assist with identification and repatriation, while acknowledging “the pain and uncertainty” of families still waiting for their missing family members.
