[Updated 6:02 p.m.] An industrial accident at Russia's largest coal mine has left eight people dead, the Interfax news agency reported early Sunday.
More than 60 miners remain underground in the mine, near the central Siberian town of Mezhdurechensk, where 359 people had been working when the accident occurred at 11:55 p.m. Saturday (12:55 p.m. ET)., according to Russia's Emergency Ministry.
At least four of those rescued from the mine, called Raspadskaya, have injuries, Interfax and the state-run RIA-Novosti news agencies reported. Early media reports suggested the accident was a result of a methane explosion, which are relatively common in Russian mines, but local officials later said the accident was caused by a partial rock collapse inside the mine.
Russian President Dmitry Medvedev and Prime Minister Vladimir Putin phoned the local governor and the head of the Russian Ministry for Emergency Situations and said accident response would happen locally, without help from federal agencies, Interfax said.
Mezhdurechensk is about 2,000 miles east of Moscow. CNN could not immediately reach authorities in Siberia.
