A catastrophic flash flood triggered by a glacial collapse along the Nepal-Tibet border has killed nearly 400 people and left hundreds missing.
Search crews across Nepal and Tibet are racing against time to locate survivors.
The destruction began on Wednesday morning when a massive wall of mud and water crashed downstream, sweeping away houses, roads, and bridges.
According to the BBC, Nepalese police confirmed the domestic death toll has climbed to 389, while Chinese officials reported three fatalities in Tibet.
With over 900 people listed as missing, rescuers must navigate ruined terrain under constant threat of new landslides.
Hundreds of international travelers remain uncontactable across the remote border region.
Officials reported missing tourists from India, the United States, Ukraine, and the United Kingdom, alongside dozens of missing local security personnel.
Misread by instruments
A magnitude 5.2 seismic event initially pointed to an earthquake as the main trigger.
Updated assessments by the US Geological Survey later clarified that a massive glacier breakdown released a devastating torrent of mud and rock down the valley.
The violent surge destroyed critical transit infrastructure at the Gyirong land port, a key trade and pilgrimage connection between China and Nepal.
The critical border route had barely been operational since its restoration on January 1, following a near-identical disaster in mid-2025.
Local families described terrifying escapes from the sudden surge. One Nepalese relative told the BBC that his surviving parents managed to get away by “crawling like a baby” into the hillside as the mud water approached.
Desperate rescue attempt
To support the search effort, Nepalese authorities have dispatched a 13,000-strong force comprising military and law enforcement officers to the disaster zones.
Nepalese Prime Minister Balendra Shah confirmed that rescue crews completed 69 flights across the day to evacuate 573 injured survivors to medical camps.
Aid organizations are warning of a severe humanitarian crisis in the coming days.
UNICEF representative Alice Akunga reported that over 17,000 children urgently require assistance, warning that “children who have survived the floods now face heightened risks of disease, malnutrition, violence and exploitation,” according to BBC.
Relief agencies are appealing for immediate international funding to scale up emergency operations.
Rescuers continue to pick through dense layers of mud and debris, working under the constant threat of secondary floods.
