Dozens of people were injured Tuesday when a metro train derailed in Moscow, local media said.
"At least 50 people were injured, most of them have got bruises. Evacuation of people continues in metro station Slavyansky Bulvar (in west Moscow)," an unnamed law enforcement source told Itar-Tass news agency.
Another emergency agencies source told Interfax news agency that at least 30 people were hurt after three train cars "came off the rail but did not capsize."
Part of the "deep blue" metro line was suspended, and more than 60 buses were sent to carry affected passengers. The cause of the incident is yet to be determined.
