Eight people have been killed and 19 others remained missing after a flash flood and mudslide struck the city of Kangding in Sichuan province, local authorities said.

A tunnel bridge was toppled and homes were destroyed in Ridi Village, which is located in a valley at an altitude of 1,300 metres above sea level.

More than 1,500 rescuers were deployed and 939 residents were relocated.

Meanwhile, the Ministry of Emergency Management called on authorities to stay on guard against floods as significant rainfall is forecast to continue in certain areas in the coming days.

The ministry also called for intensified drainage and epidemic prevention work, as well as faster post-disaster construction. (Xinhua)
