Devastating floods in Nepal and Tibet have claimed at least 270 lives, with over 1,000 people still missing. Experts believe a glacial collapse in the Himalayas triggered an avalanche of rock and ice, causing widespread destruction. The disaster struck Wednesday along the border region between the two countries, engulfing areas in debris. Nepali tourism officials have confirmed four French nationals are among those unaccounted for. Rescue teams are actively searching for survivors, facing challenging conditions in the remote mountain terrain. The scale of the catastrophe continues to unfold as assessments are made and further reports emerge from the affected areas.
