A catastrophic flash flood that struck Nepal's Bhote Koshi River, originating from Tibet, has disrupted the Kailash Mansarovar Yatra, with approximately 384 pilgrims out of contact near the Rasuwagadhi border. No formal cancellation order has been issued by the Government of Nepal or the Ministry of External Affairs (MEA) as of yet. However, tour operators in Kathmandu have halted departures for the next 48-72 hours due to safety concerns. According to the Nepal Tourism Board's preliminary data, 291 foreign nationals and 93 Nepali nationals scheduled to cross into Tibet on Wednesday are unaccounted for. A massive flood has reportedly swept away a building housing at least 77 pilgrims from one group near Tibet's Gyirong, as captured in a video showing a mud and water surge engulfing the structure. The flood occurred between 8:30 and 9:15 am, leading to the collapse of the Nepal-China Miteri Bridge and disrupting road and communication networks along the key pilgrimage route. While the MEA-organized Yatras via Lipulekh Pass in Uttarakhand and Nathu La in Sikkim are proceeding as planned, the Rasuwagadhi-Kerung route, Nepal's oldest trade and pilgrimage route to Tibet, is currently blocked. The affected route has suffered damage to roads in Rasuwa, collapsed bridges over the Trishuli River, disrupted fibre and mobile networks, and blocked the Prithvi Highway to Chitwan and Pokhara. The Trekking Agencies' Association of Nepal (TAAN) is urging the Nepalese Foreign Ministry and Chinese Embassy to establish alternative crossings at Tatopani, Korola, and Hilsa for pilgrims and simplify visa clearances. This year, Nepal was expected to host around 25,000 Indian pilgrims for Kailash Mansarovar after the Yatra resumed following a five-year hiatus. Officials report no confirmed injuries among the pilgrims, with loss of contact attributed to the collapse of communication networks in the border area. Verification is ongoing through the Tourist Police, government agencies, and security forces. Families of affected pilgrims are advised to contact the Indian Embassy helpline in Kathmandu and the NTB control room.
