Nepal-Tibet floods: What happened, what caused them and who is missing?

At least 160 people were killed and nearly 1,500 remain missing after a Himalayan glacier collapse triggered catastrophic flash floods and mudslides along the Nepal-Tibet border. The disaster swept through the Lhende Khola river valley, destroying homes, bridges, and roads, while rescue efforts are hampered by high river levels and damaged infrastructure. Officials were caught off guard because the floods occurred without rain, with the trigger being a glacier collapse high in the Himalayas.
