Nepal Rescuers Pump Air Into Flooded Hydropower Tunnel

AFP, carried by the South China Morning Post and The Straits Times, reported that drills opened the upper part of a mud-swamped tunnel at Trishuli 3A on Saturday evening. Gurung's statement said air was already moving through the small opening and that excavation and an entry team would come next. The Energy Ministry added that camera and oxygen attempts had begun. Those are the mechanics of a race against time in a confined space: air first, eyes second, people third. Whether anyone is still breathing on the other side of that hole is the question the camera is meant to answer.

The same disaster authority that listed 933 missing hydropower workers has said more than 100 may still be alive in multiple tunnels. Rescue focus is on Trishuli 3A and 3B in Rasuwa. China sent tunnel specialists after a direct request from Kathmandu. Xinhua said five experts were flown by helicopter from Gyirong county in Tibet on Saturday afternoon to join the hydropower-site operation. Later SCMP reporting put the Chinese specialist group at nine. Either figure is a small technical team, not a mass deployment. Nepal has been asking for tools more than battalions: heavy-lift drones, location gear, forensic kits, and freezer capacity for bodies recovered from water.

Why It Matters

Hydropower is how Nepal sells electricity and how it talks about development. The same rivers that fund that story sit under collapsing ice. A glacial failure on the Tibet-Nepal line turned an energy landscape into a mass-casualty site in a morning. The missing list mixes tunnel crews, trekkers, and Hindu pilgrims headed toward Mount Kailash. The Isha Foundation said 80 of its members were on a group trip in the area and, as of Saturday, saw no encouraging signs of survivors near the immigration office.

Sunday's numbers, as compiled by the Guardian from Nepali and Chinese updates, were 734 dead and 2,498 missing in Nepal, and 16 dead and 546 missing in Tibet, of whom Chinese state media said 261 were foreign nationals, including 104 from Nepal, 49 from India, 33 from Latvia, and 18 from the United States. India recovered seven bodies from rivers flowing out of Nepal. Those figures will move. They already have, day to day. What will not move quickly is the geology. A new lake formed by ice and mud paused Chinese operations at Gyirong until authorities later said it was discharging and essentially drained. Nepal's disaster agency warned at 7:20 a.m. Sunday that flow in the Bhotekoshi River in Rasuwa had risen again and told rescue teams to be careful.

Foreign Minister Shisir Khanal put reconstruction in the billions of dollars and asked for specialized help rather than a generic surge of searchers. The United States and Canada each announced $3.6 million in humanitarian aid. The United Kingdom offered $6.8 million. The United Nations released $2.5 million. The European Union pledged $2.3 million. The International Federation of Red Cross and Red Crescent Societies allocated more than $1 million and launched a $31 million emergency appeal. That is real money and still a fraction of a Himalayan rebuild.

Political Context

Kathmandu and Beijing have a border, a trade gate at Gyirong, and a shared river system that does not respect either. The two foreign ministries spoke Saturday about satellite and hydrological data. On the Chinese side, Xinhua is the only detailed source: 2,141 rescuers near Gyirong, more than 500 in the worst-hit pocket, and a pause when the new lake looked unstable. On the Nepali side, the army, police, and disaster authority are running a corridor rescue with helicopters that have already shuttled hundreds off ridgelines. Indian mountain teams are in the mix as well, per Straits Times reporting.

UN climate chief Simon Stiell, in a statement quoted by The Straits Times, called the collapse a reminder of how fragile these mountains are as glaciers recede. That is the long argument. The short one is that a 72-hour survival window for people underground is already behind the calendar. Saturday's air pipe is what you do when the window is closed and you still refuse to treat the tunnel as a tomb.

Relatives in Kathmandu have been circulating between hospital desks and noticeboards since the first lists went up. The Guardian described families arriving from districts hours away with photographs of hydropower drivers and site workers. An army hub in Bidur posted rescued-name sheets on a wall. Those are the politics that do not need a briefing: a state that cannot name its dead fast enough, and a workforce that was underground because the country puts generation in the same valleys that flood.

What Officials and Groups Are Saying

Gurung's ministry framed Saturday night as the start of an entry sequence, not a completed rescue. The Energy Ministry claimed only partial success on the drill. The Prime Minister's Office had earlier reported 350 people already taken out of tunnels under what it called extremely risky conditions, with more than 100 still inside. China's Ministry of Emergency Management said the Tibetan tunnel team was dispatched urgently at Nepal's request. Khanal's public ask was for drones, location technology, DNA kits, and cold storage. Nepal's disaster authority told crews on Sunday to treat the Bhotekoshi rise as an active threat, not background weather.

Chinese state television reported the Gyirong lake as naturally discharging and essentially drained by late Saturday, which would allow searchers back onto ground they had just abandoned. That claim sits next to Nepal's Sunday morning flood warning. Both can be true in different stretches of the same river system. The data-sharing talk between the two foreign ministers is an admission that neither capital can see the whole catchment alone.

Timeline

• Aug. 26, 2026, morning: Glacial collapse on the Nepal-Tibet border sends a wall of water and debris down the Bhote Koshi-Trishuli corridor, per the U.S. Geological Survey
• Aug. 27-28: Nepali army reports large-scale tunnel extractions; the Prime Minister's Office cites 350 pulled from tunnels and more than 100 still trapped
• Aug. 29, Saturday: Chinese tunnel specialists fly from Gyirong to the hydropower site; army drills break into the upper Trishuli 3A tunnel and begin pumping air
• Aug. 29 evening: Energy Ministry reports partial drilling success and attempts to send a camera and oxygen
• Aug. 30, 7:20 a.m.: Disaster authority warns of increased flood flow on the Bhotekoshi in Rasuwa
• Aug. 30: Combined fatality and missing counts continue to rise on both sides of the border as excavation toward the trapped crews continues

Frequently Asked Questions

Where are the trapped workers?
Rescue work is concentrated on tunnels at the Trishuli 3A and 3B hydropower sites in Nepal's Rasuwa district. Saturday's air pipe went into Trishuli 3A.

How many people might still be underground?
The government has said more than 100 workers may still be alive in hydropower tunnels. Separately, 933 hydropower workers are listed among the missing, which includes people unaccounted for above ground as well.

What caused the flood?
The U.S. Geological Survey said a glacial collapse on the China-Nepal border produced the torrent on Aug. 26. The exact trigger of that collapse is still being studied.

Is the death toll final?
No. Sunday compilations put combined deaths around 750 and the missing above 3,000. Bodies have been recovered downstream in India, and identification is incomplete.

What happens next at the tunnel?
If the air line and camera show a survivable space, crews will widen the opening and send a team in. Rising river levels can halt that work without notice.

What Happens Next

The next hours at Trishuli 3A are a technical problem with a human clock: keep air moving, get a picture, decide whether an entry team can live in that space. The next days on the Bhotekoshi are a hydrological problem: another pulse of water can close the hole they just opened. The next months are a reconstruction problem Kathmandu has already priced in the billions. For the families at the hospital wall, none of that is abstract. They are waiting on a camera feed from a tunnel that was not supposed to become a grave.
