Twelve workers were killed and one injured in a flood in a coal mine in southwest China's Guizhou province, state media said Thursday.

The brief report by the Xinhua news agency did not provide further details of the accident, the latest to strike the country's notoriously dangerous mining sector.
More than 2,600 miners were killed in job-related accidents last year, according to official data -- or about seven people a day. Independent labour groups say the actual number of deaths is probably much higher.
