A massive flood that swept through the Himalayan mountainous region on the Nepal-China border has killed at least 750 people and left more than 3,000 missing. There are concerns about the survival of over 100 people trapped in a hydroelectric power plant tunnel, and rescue teams are working to create access routes and inject air, hoping for a miracle. However, they are facing difficulties due to fears of further flooding caused by heavy rain and a lack of specialized equipment. The international community is providing humanitarian aid and support from experts to help Nepal recover from the disaster. The Korean government and companies have also deployed helicopters and drones to search for nine missing Koreans. The Nepalese government estimates that approximately $5 billion will be needed for disaster recovery and is requesting assistance from the international community.
