MOSCOW (Reuters) - A train on the Moscow subway went off the rails between two stations on Tuesday, injuring up to 50 people and leaving about 20 trapped, Interfax news agency quoted a law enforcement official as saying.
"We have information from witnesses that the train braked suddenly as a result of which several cars were derailed," a spokesman for the emergency ministry told Reuters.
At least two people were in a serious condition and were being taken to hospital by helicopter, Russian television said.
