The group comprised 34 men and 46 women, along with three volunteers and a doctor who were staying at nearby hotels.He said a building used for immigration formalities just a week earlier, along with part of the nearby town, had been washed away.

The resulting debris flow entered the Bhote Koshi river before surging through Rasuwagadhi, Timure, and Syaphru Besi into the Trishuli river, triggering emergency conditions across Rasuwa, Nuwakot, Dhading, Gorkha, and Chitwan districts.Nepal Army and private helicopters have been deployed for search and rescue operations, while temporary shelters, food, water, and medical aid have been set up at army barracks for displaced families. NDRRMA said priorities now include rescuing survivors, treating the injured, restoring blocked infrastructure such as roads, bridges, and communication lines, and relocating affected families to safety.With inputs from ANI
