Smoke in the Broadway-Lafayette Subway Station?

One of our spies is reporting that the 6, B, D, F, V station at Broadway and Lafayette is filled with smoke. "It's the whole station, but trains are still running." Could it just be a bunch of French tourists? "You can see and smell smoke," explains our legwoman. "But no idea what happened." Anybody there? Care to fill us in on what's going on?
