Russia derailment: 'Three dead' in Moscow metro crash Russia derailment: '10 dead' in Moscow metro crash
(about 1 hour later)
A train has derailed in the Russian capital Moscow, killing at least three people, injuring many more and leaving some passengers trapped, officials say. The number of people killed in a rush-hour derailment on the Moscow metro has risen to about 10, the deputy mayor has said, with scores injured.
A statement from the metro said only that a train derailed on the network's blue line, without providing any details, the AFP news agency reported. Some of those hurt were carried out of the tunnel on stretchers, with the most serious cases airlifted to hospital.
There is no word as to the cause of the crash, in the west of the city. The cause of the crash is reported to be a power surge, which prompted the train to stop abruptly.
The Moscow metro is one of the oldest and most extensive underground railway systems in the world. It is one of the most serious incidents in the history of the metro, one of the world's oldest underground railways.
Some of the most seriously injured passengers were taken to hospital by helicopter, Russian TV said. The train derailed between Slaviansky Boulevard and Park Pobedy (Victory Park) stations in the west on the city.
The train derailed in a tunnel between stations. Some 50 people were in a serious condition, the Itar-Tass news agency reported, quoting a health official.
The packed commuter train was travelling from the north-west of Moscow to the city centre at the time of the crash.
At least 200 passengers were evacuated, officials said.
Dozens of people were treated at the scene for their injuries.
The BBC's Artyom Liss, in Moscow, says the tunnel where crash happened was built about 10 years ago.
Critics accuse the authorities of spending too much on extending the metro system, and not enough on maintenance, our correspondent says.
