A severe flood, potentially triggered by a glacial collapse, has ravaged remote areas of Nepal and Tibet, obliterating settlements, bridges, and border stations. A Chinese rescue team reaching the Rasuwagadhi border crossing on Friday described the scene as "nothing but ruins."

Satellite imagery depicts entire communities vanishing under the torrent of mud and water that swept through the region on Wednesday. The Rasuwagadhi crossing, a key point on the border between Nepal and Tibet and located at one end of the Friendship Bridge, has been entirely erased from the landscape. CCTV footage captured people fleeing moments before the floodwaters engulfed buildings at the site.

The disaster has officially claimed at least 626 lives, with authorities reporting 2,426 people still missing as of Saturday. Among the missing are approximately 540 foreign tourists, including 33 British nationals. Many foreign visitors were believed to be in the area for pilgrimages or trekking expeditions, particularly near the Langtang valley and the holy Mount Kailash.

Rescue efforts are ongoing but are hampered by difficult conditions, including challenging terrain, adverse weather, and the sheer magnitude of the disaster. The Trishuli River has overflowed its banks, carrying away homes, buildings, and infrastructure. Villages such as Syapru Besi have suffered widespread devastation, with many ground-level structures washed away. Bridges spanning the Trishuli River have been destroyed, leaving behind only mud and silt.

Chinese state media reported seven deaths and 554 missing in Tibet. In Nepal, around 93,000 people have been affected, many losing their homes. The economic impact is substantial, with the Finance Minister estimating recovery costs could reach $5 billion, roughly a tenth of the nation's economy. The recovery of bodies has posed significant challenges, with authorities struggling with identification and storage due to decomposition.

Authorities are seeking specialized technical assistance to reopen transport routes, replace bridges, and manage the recovery of the deceased. The British Foreign, Commonwealth and Development Office confirmed 33 British nationals are missing and stated a Rapid Deployment Team has been sent to Nepal to support affected citizens and their families. The UK government has pledged £5 million to aid Nepal's crisis response.

Army rescue teams are working to free more than 100 people trapped inside a hydropower tunnel. These efforts are complicated by adverse weather and debris.

Among the missing Britons are a family of four from Surrey, including a former Mrs. India UK, and a 14-year-old boy. Multiple citizens were on pilgrimages to Mount Kailash. Tour operators have reported being unable to account for several UK nationals who were part of various trekking groups.
