Moscow ? Russian state television says the death toll from two explosions in the country’s largest underground coal mine has risen to 30, with about 60 people still trapped.

Rossiya 24 television says the government official heading the rescue operation announced the news during a briefing this morning at the Siberian mine.

Rescue workers have been able to go down into parts of the mine hit by two explosions over the weekend. High levels of methane gas have raised fears of further explosions and hindered rescue efforts.
