CHENGDU -- A rain-triggered landslide in southwestern Sichuan Province blocked a national road and stranded four people Wednesday morning, local authorities said.

The landslide hit the Yajiang section of National Highway 318 in Yajiang County at around 6 am, witnesses said.

Wang Qi, chief of fire brigade in the county, said he sent a rescue team to the area at 7 am and the four stranded people were rescued around noon.

More than 20 cars were hit by the landslide, but no casualties had been reported.

Downpours have battered Yajiang since Tuesday.
