Officials in Beijing have launched all-out disaster relief and rescue operations in the last four days after a fresh spell of intense rainstorms damaged roads, disrupted power supply, and prompted mass evacuations.

Beijing city officials have admitted failures in their response to heavy flooding that killed 31 residents of a care home.

At least 30 people have died in Beijing and more than 80,000 were evacuated to safety, Chinese authorities said, as heavy rains and floods ravage roads and houses in northern China. Eight other people died after a landslide on Monday in Chengde city, about three hours northeast of Beijing.
