Ten miners were killed and seven missing Monday when a methane explosion tore through a coal mine in the remote Russian Far North town of Vorkuta within the Arctic Circle, the emergencies ministry said, the latest disaster to hit the country's mining industry. A total of 259 miners were working underground when the explosion occurred at the Vorkutinskaya mine in the Komi region controlled by Russian steel-making giant Severstal. Most of them have been evacuated but when the rescue workers arrived at the scene they found 10 bodies, the ministry said.
