A landslide in China's Sichuan province has buried between 30 and 40 people, Chinese state media say.

The landslide occurred in Zhongxing town on Wednesday morning. More than 100 rescuers with rescue dogs were at the scene, Xinhua news agency said.

Parts of China have been hit by torrential rainfall in recent days, causing floods in some places.

On Tuesday, a bridge in Sichuan's Jiangyou collapsed, with at least 12 people missing.

Zhongxing is in Dujiangyan city, one of the places badly hit by the 2008 Sichuan earthquake.
