At least 157 people have been killed and hundreds, including many foreign tourists, are missing after flash floods struck the Nepal‑Tibet border region, sweeping away roads, bridges and power infrastructure. The floods were triggered by a sudden surge of mud, water and debris from a river that runs along the border between China and Nepal, according to local officials. Nepalese authorities reported the death toll and said numerous homes and transportation routes were destroyed, while Tibetan officials warned of possible major casualties. Rescue operations were underway, with teams searching for survivors amid debris. The incident highlights the vulnerability of remote mountainous border areas to extreme weather events, and authorities have not yet released a full assessment of the damage or the number of missing persons.
