Beijing officials say a group of older people trapped in a nursing home that flooded were among the dead in powerful storms that lashed the city and neighboring provinces.

The dayslong rainstorms have left 30 dead in the Chinese capital and eight dead in its neighboring province of Hebei, state-run broadcaster CCTV said.

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.
