Smoke shuts down D.C. metro station

The smoke was thick enough to prompt WMATA to suspend service on several lines, including parts of the Green and Yellow line, which both stop there. Blue, Orange and Silver lines were bypassing the stop.

Mass Casualty incident declared at L'Enfant Metro Station.
