A massive mudslide engulfed the Gyirong border crossing between Nepal and China on Wednesday, killing at least 22 people [1].

The disaster occurred at a critical transit point for international travelers and local residents. Because the site serves as a gateway between Tibet and Nepal, the high number of missing persons includes foreign nationals from various countries.

CCTV footage from the scene captured people attempting to flee seconds before the debris hit the port [2]. The mudslide struck the Gyirong border crossing in Tibet, sweeping through the area where tourists and residents were gathered [2].

Reports indicate that hundreds of tourists are currently missing [1]. Among those caught in the disaster are nationals from the U.S., the United Kingdom, India, and Malaysia [2].

Authorities are investigating the cause of the sudden collapse. Nepal's Foreign Minister Shisir Khanal said initial reports suggest an earthquake in the area could have triggered an avalanche and caused the floods [3].

The event took place on Aug. 26 [2]. Emergency responders are working to locate survivors among the debris at the Gyirong Port, though the scale of the mudslide has complicated rescue efforts [2].

Rescue teams are coordinating across the border to identify the missing and recover bodies. The sudden nature of the slide—captured in video—shows the limited time victims had to react before the flow of mud and rock overwhelmed the crossing [2].

At least 22 people dead

The Gyirong crossing is a vital link for trade and tourism between Nepal and China. A disaster of this scale, potentially triggered by seismic activity, highlights the extreme geological vulnerability of the Himalayan region. The presence of multiple foreign nationals among the missing will likely necessitate a complex, multilateral diplomatic and search-and-rescue operation between Kathmandu and Beijing.
