Coal mine blast kills 28 in northeast China
{{#rendered}} {{/rendered}}A gas explosion at a coal mine in northeast China has left 28 people dead.
China's State Administration of Work Safety said Saturday that the cause of the blast late Friday at a state-owned mine outside the city of Baishan in Jilin province is under investigation.
Other than the 28 dead, the official Xinhua News Agency says 13 people were rescued.
