Eyewitness Narrates Horror Of Deadly Nepal Floods: "How Many Dead We Do Not Know..."

Flash floods in a border area of Nepal and China on Wednesday have killed at least 160 people and left hundreds missing. Experts said an avalanche from a glacier was the likely cause in the warming Himalaya region. Drone footage shows roads destroyed and buildings buried. Officials in Nepal say 403 people, including 341 foreign nationals, are missing. Many were on a pilgrimage to a sacred site. The U.S. Geological Survey first reported an earthquake then called the shaking a 5.2 magnitude landslide.
