The death toll from a mudslide triggered by heavy rain on the outskirts of the western Chinese city of Xi’an rose to 21 on Sunday and rescuers were still looking for six missing people, the government said.

The mudslide and a flash flood on Friday evening also damaged a highway and knocked out power to 900 households, the Xi’an Emergency Management Bureau said on its social media account. It said rescue teams totalling 980 people with dogs were looking for the remaining missing people.
