Flash floods in a border area of Nepal and China have killed at least 98 people. Officials in Nepal say 403 people are missing, including 341 foreign nationals. Many were said to be Indians on a pilgrimage to Mount Kailash in China’s autonomous region of Tibet. China’s state broadcaster said a mudslide in Tibet killed at least three people and left 265 missing, and state news agency Xinhua reported significant casualties. The floods destroyed communities and roads. Nepal said it has asked India and China to help. The Himalayan region is especially vulnerable to disasters linked to human-caused climate change.
