A flash flood and subsequent mudslides in the Rasuwa region near the Nepal-Tibet border have resulted in at least 95 confirmed deaths in Nepal and three in Tibet, with hundreds of people missing. According to Nepal's Tourism Board, 33 United Kingdom nationals are among the 403 individuals unaccounted for.
An excursion company, Alpine Eco Trek, reported that 12 British nationals and two Irish nationals on a tour across the Nepal-Tibet border are believed to be among the missing. The ages of the British citizens reported missing range from 13 to 65. The UK Foreign Office stated it is collaborating with Nepalese authorities regarding the reports of missing British nationals and has advised UK citizens in Nepal to follow local guidance and remain vigilant.
The incident occurred early Wednesday morning in Rasuwa, a district north of Kathmandu. Preliminary reports suggest the flash flood was triggered by an earthquake that caused an avalanche, leading to melted snow pouring into the Bhote Koshi river. CCTV footage captured a surge of water and mud inundating buildings near a border crossing, and video from a bus in Trishuli showed people attempting to escape the floodwaters.
Chinese state media reported that a mudslide in Tibet's Gyirong killed three people and left 265 missing, with ongoing rescue operations. In a joint statement with Australia, the EU, Finland, France, Norway, and Switzerland, the British embassy in Nepal urged British nationals in the country to exercise caution in affected areas.
