A devastating flood disaster in the Himalayan border region of Nepal has triggered an urgent search and rescue operation after 77 trekkers from a tour connected to a U.S.-based nonprofit organization went missing, cutting off all communication with the outside world. In the wake of this alarming incident, BBC correspondent Helena Humphrey traveled to the Isha Foundation’s headquarters in Tennessee to speak with organization representatives about the missing expedition. The group had been traveling along the remote China-Nepal border when floodwaters swept through the area, destroying communications infrastructure and leaving no trace of the hikers’ whereabouts in the days since the disaster. Remote mountain terrain in the region has complicated efforts to locate and reach the missing group, with heavy rainfall worsening flood risks and slowing rescue deployments. The Isha Foundation, a global spiritual and wellness organization that regularly organizes wilderness retreats and trekking expeditions, has confirmed that the tour was operating under its auspices, and has not issued any further updates on the status of the search as rescue teams continue navigating hazardous conditions to reach the affected area.
