Flood risk forces halt to rescues in Tibet, as Nepal death toll rises to 469

Flood risk has forced the withdrawal of rescue teams from the epicentre of a catastrophic flood in Tibet, while the death toll in Nepal has climbed to 469 and more than 1,300 people remain missing, including hundreds of tourists. A lake that has formed behind a wall of mud and debris at the border town of Gyirong has begun to overflow, prompting Chinese authorities to order all rescue units to stand down until further instructions are issued.

The lake, created by the sudden collapse of a debris dam, is expected to rise over the next three days as rainfall continues. State broadcaster CCTV warned that the rising water could breach the dam, sending floodwaters downstream toward Gyirong Port and other downstream settlements. As a result, emergency teams that had previously reached the site were ordered to retreat one kilometre and to wait for further guidance.

The flash flood that struck the region on Wednesday devastated valleys on both sides of the China–Nepal border. In Tibet, the wall of mud and debris that collapsed at Gyirong triggered a torrent that swept through villages and destroyed infrastructure. Chinese state media have reported only three deaths in Tibet, but the limited information released reflects the tightly controlled flow of news in the region. At least 558 people are missing on the Tibetan side, including 260 foreign nationals, according to CCTV. The Chinese authorities have confirmed that 499 Chinese nationals and 555 foreigners have been evacuated from the disaster zone.

In Nepal, the death toll has risen to 469, with the number of missing rising to more than 1,300. Police and tourism officials say that of the missing 826 people, 500 are foreign citizens. The missing include 177 Indians, 90 Americans, 34 Australians, 33 Britons and 25 Canadians. The flood has also claimed the lives of 100 Nepalese nationals, bringing the total death toll in the country to 469.

Search and rescue efforts in Nepal have been hampered by the destruction of dozens of bridges and miles of roads in the mountainous region, which is a popular trekking and pilgrimage destination. Army helicopter crews have been conducting operations to rescue workers trapped inside the tunnel of the Trishuli 3A hydropower project, which was inundated by the flood. Nepal Army spokesperson Raja Ram Basnet said that two helicopters had been dispatched, but locating the tunnel’s entry points proved difficult. The army has already rescued 350 workers and local residents from the tunnel, according to the prime minister’s office.

Rescue teams have also found bodies hundreds of miles downstream in the Chitwan district near the Tibetan border. Dozens of injured people have been transported to Kathmandu for advanced medical care, and more than 100 people have been rescued by Nepali army personnel in helicopters.

The international community is working to deliver aid to flood‑stricken areas of both Nepal and Tibet. However, the destruction of infrastructure has made relief operations challenging. The situation remains fluid, with authorities in both countries continuing to monitor water levels and the integrity of the debris dam in Tibet. As rainfall persists, the risk of a breach that could exacerbate flooding downstream remains a major concern for officials on both sides of the border.
