(CNN) -- The death toll from a mud and rock slide in northern China has reached 56, China's state-run news agency reported Tuesday.
Torrential rain caused the slide at about 8 a.m. Monday, resulting in the collapse of a warehouse in China's Shanxi Province, the Xinhua new agency reported, quoting rescue workers.
Witnesses said the flow of rocks and mud roared down a valley, the agency said.
The deluge also destroyed a three -story office building, a market and some villagers' homes in the valley. Thirty-five people were injured, the agency reported.
More than 1,100 police, firefighters and others were part of the search effort, the agency reported.
