A gas blast at a coal mine in the north east China has claimed the lives of 28 workers besides injuring other 13 workers.

The incident was reported at Babao coal mine in the city of Baishan, Jilin province. The mine is owned by state-owned colliery under the Tonghua Mining Group, reported Xinhua news agency.

A provincial work safety and supervision bureau spokesperson stated that the injuries of 13 were not life-threatening.
