At least six are dead and 70 others injured after two subway trains collided during rush hour this evening in Washington DC, the AP reports. The incident is “developing into a mass casualty event,” a Metro spokesman told WJLA-TV. “We’re expecting a number of injuries.” A train on the Red Line, the system’s busiest, plowed into another train stopped at a station, Metro's general manager said at a press conference.
The scene is “terrible,” a spokeswoman tells WTOP-AM, adding that firefighters were working to free dozens of passengers trapped inside. “One rail car is about a third of the way on top of another rail car.”
