The death toll from a mudslide in China’s northwestern city of Xian has risen to 21, with 6 people still missing, the city’s emergency management authority said, as China grapples with unusually high summer rainfall.

State-owned China Central Television (CCTV) had earlier reported that mudslide left a total of 18 people dead or missing, with 2 confirmed casualties.

A video released by the official Xinhua news agency showed broken trees and rubble piling up along muddy roads in a village, with houses and infrastructure damaged or destroyed. The mudslide destroyed 2 houses and cut power to 900 households, the authority said in a statement on its WeChat account.
