A rain-triggered mud-rock flow in northern China's Shanxi Province caused the collapse of a warehouse holding waste ore dregs on Monday, killing one and trapping others, according to the local government.

The accident occurred around 8 a.m. in a warehouse of the Tashan Mine in Xiangfen County, Linfen City, which has been soaked by torrential rain.

One person was killed at the scene and another was injured.

A Xinhua reporter said more people were trapped underneath the structure but a specific figure was not immediately available.

A rescue team of more than 300 local police and villagers were searching through the rubble.
