A powerful flash flood has swept through the Nepal-Tibet border region, resulting in at least 18 confirmed deaths. Preliminary reports indicate that more than 100 individuals from India and 12 from the United Kingdom are among the missing. The scale of the disaster was captured in video footage showing the moment the floodwaters struck the area. The BBC has edited the video with white flashes to account for its distressing content. Further details on the ongoing rescue efforts and the full extent of the casualties are still emerging.
