A rush-hour subway train derailed in Moscow Tuesday, killing at least 10 people and injuring at least 95, emergency officials said.
Several cars left the track in the tunnel after a power surge triggered an alarm, which caused the train to stop abruptly.
City Hall officials gave the death toll as four. At least 95 people were hospitalized, of whom 50 are in grave condition, Itar-TASS said quoting Moscow's health department chief, Georgy Golukhov.
Yuri Akimov, a Moscow representative of the emergency services, said in a televised briefing outside the Park Pobedy station that about 200 people were evacuated from the train, which was stuck between two stations in west Moscow.
Several people who were gravely injured were taken out of the nstation and airlifted from the scene. Photos on social media showed passengers walking along the tracks ninside the dimly lit tunnel.
A man with a bloody cut on his brow told Rossiya 24 television outside the Park Pobedy station that he felt a jolt and the train abruptly came to a halt. ``There was smoke and we were trapped inside,'' the man said. ``It's a miracle we got out. I thought it was the end.
Park Pobedy is the deepest metro station in Moscow, 84 metres (275 feet) deep, which is making the rescue particularly hard.
While accidents are regular occurrences in the Moscow Metro, deadly incidents are rare.
