At least 90 people have been killed in a gas explosion at a coal mine in China’s northern Shanxi province, marking the country’s deadliest mining accident since at least 2009. The explosion occurred at the Liushenyu coal mine in Qinyuan County, where 247 workers were underground at the time, state media reported. By early Saturday, 201 workers had been brought safely to the surface. President Xi Jinping called on authorities to 'spare no effort' in treating the injured and carrying out search and rescue operations. He also ordered a thorough investigation into the cause of the accident and stressed that those responsible should be held strictly accountable under the law. #china #news #coal #mining
