Nepal Races to Reach Hundreds Trapped in Flooded Tunnels as Death Toll Passes 780

.

A Race Against Water and Mud

Nepal's military flew heavy machinery by helicopter to a remote dam construction site high in the Himalayas on Sunday, part of an intensifying effort to reach workers trapped inside a flooded tunnel. It has been four days since a wall of ice, rock and water tore down a mountain valley on the border with China's Tibet region.

The disaster has become one of the deadliest natural catastrophes to hit Nepal in recent memory. Authorities have confirmed more than 780 deaths, while over 3,000 people remain unaccounted for. The flood also knocked out roughly a tenth of the country's electricity generation capacity, tearing through several hydropower stations still under construction.

Thousands of Workers Unaccounted For

The hardest-hit sites are hydropower projects along the Trishuli and Bhote Koshi rivers, where entire tunnel systems were buried under debris. According to Nepal's Independent Power Producers' Association, roughly 900 workers from these projects were initially unaccounted for; several hundred have since been pulled to safety, but a large number remain missing.

The most urgent operation is unfolding at the Upper Trishuli hydropower complex, which straddles the Nuwakot and Rasuwa districts. Officials say dozens of workers may still be trapped inside one of its tunnels, roughly 180 meters from the entrance. Around 10,000 Nepali soldiers have been deployed nationwide for tunnel rescue work, according to Dharam Raj Uprety, head of Nepal's disaster management authority.

"It's very tough because there's a lot of debris and we cannot blast things to make our way through," Uprety said.

First Breakthrough at the Tunnel Entrance

Rescue teams reached the entrance of one blocked tunnel on Sunday and began clearing debris, marking the first real breakthrough after days of setbacks. Overnight rain and rising river levels had repeatedly flooded the excavation site, forcing crews to pause and restart their work using drills, excavators and hydraulic cutters.

Once the entrance is fully cleared, teams equipped with oxygen supplies and cameras plan to move inside to check on conditions and search for survivors. The Nepali army has already released images of two mud-covered men being pulled from one tunnel mouth. Local estimates, based on accounts from nearby villages rather than confirmed records, suggest 35 to 40 people may still be trapped in that section alone.

International Support Pours In

Both India and China have sent specialized tunnel-rescue teams to support Nepali forces at the hydropower sites. China's disaster response ministry dispatched tunnel experts to assist directly at the Upper Trishuli project, while Indian medical and rescue specialists have carried out aerial assessments of the wider disaster zone. Despite the political rivalry the two Asian giants often display elsewhere, this shared crisis has for now produced pragmatic, joint technical cooperation on the ground — a reminder that basic human solidarity can outlast diplomatic friction, even between Beijing's ruling Communist Party and its democratic neighbor to the south.

Mass Graves as Morgues Overflow

The scale of the disaster has overwhelmed Nepal's ability to store and identify the dead. In Chitwan district, nearly 200 kilometers from the flood zone, authorities have dug hundreds of graves in Devghat forest to bury bodies too decomposed for identification. Nearly a hundred unidentified victims were buried there on Saturday alone, with plans to bury even more.

"We were left with no other option and had to take this step. Our concern was the risk to public health posed by the rapid decomposition of the bodies," said Ganesh Aryal, chief district officer of Bharatpur, Chitwan.

To keep the process reversible, officials say every grave has been carefully documented, with identification markers placed above and below ground and DNA samples collected from each body. If relatives later come forward or genetic testing produces a match, remains can be exhumed and formally identified. Forensic teams from India are already working alongside Nepali counterparts on DNA analysis, and Nepal is coordinating separately with a Chinese team.

At Bharatpur Hospital, a temporary morgue built for 50 bodies has had to hold roughly 125, according to police officials on site, many of them badly decomposed after days in floodwater.

A Global Toll and an Uncertain Road Ahead

Among the missing are citizens of several countries beyond Nepal and China, including reported nationals from India, Ukraine, Malaysia, Australia, Britain and Canada, according to figures relayed by international outlets. The United States has pledged several million dollars in emergency humanitarian aid.

With floodwaters still rising and falling unpredictably along rivers in northern Nepal, rescue and recovery work is expected to continue for days. For families still waiting outside hospitals, temporary morgues and registration tents, the coming days will likely bring both the final confirmation of losses and, for a fortunate few, news that a missing relative has been found alive.
