Four dead and 26 missing after explosion at Russian coal mine
Explosions at a coal mine in Russia's far north Komi region have killed four miners and a further 26 are missing.
A methane gas leak late on Thursday triggered two explosions and the collapse of the mine, according to the Tass news agency. At the time of the blast, 110 miners were underground. Eighty were rescued.
The Vorkutagol coal mining company said on Friday that fire is still raging inside the mine.
Rescue efforts are continuing but Russia's state emergency service has not been able to establish a line of communication with the trapped miners, according to Tass.
The Russian investigative committee said it is looking into the explosion and the Kremlin has appointed a special commission to deal with it.
