A gas explosion at a coal mine in the northern Chinese province of Shanxi has killed 28 miners and five rescuers in the country's latest mining disaster.
Seventy-one miners were working when the accident happened at the Daxian Sankeng mine, near Yangquan, the State Administration of Work Safety said.
It did not say how the rescuers died, but a build-up of toxic gas and subsequent explosions are common in such disasters.
China's mines, which provide the main fuel for the world's seventh-biggest economy, have an appalling safety record underscored by a series of major accidents this year.
