At least 90 people have been killed in a gas explosion at a coalmine in northern China, the country's deadliest mining accident since at least 2009.
The gas explosion occurred late on Friday at the Liushenyu coalmine in Qinyuan county, Shanxi province, with 247 workers on duty underground, state media Xinhua reported.
The mine is operated by Shanxi Tongzhou Group Liushenyu Coal Industry, which was established in 2010 and is controlled by Shanxi Tongzhou Coal Coking Group, according to corporate database Qichacha.
