A landslide triggered by rain left seven people missing in Guangzhou on Wednesday, local authorities said.

A total of 14 people were trapped in the landslide that occurred at about 8.30am in Dayuan Village in the city's Baiyun District, with multiple houses damaged.

As of noon, rescuers had pulled seven of them from the debris, all in stable condition.

Nearby residents have been evacuated and further search and rescue work was under way.

Forecasters have warned of more thunderstorms after heavy rain pounded Guangzhou, forcing its Baiyun airport to cancel 363 flights and delay 311.

Rescue teams in Guangdong scrambled to open drains and pump water away from urban areas, as the intense rain set off mudslides and felled trees on highways, ripping up roads to expose cabling and other infrastructure.

On Tuesday, Beijing allocated more than 1 billion yuan in disaster relief for Guangdong and the northern province of Hebei, as well as the capital, Beijing, and the northern region of Inner Mongolia, including subsidies for damage to grain-growing areas. (Xinhua/Reuters)
