Not sure if you're still out there, but a few busses did arrive. I just left in an Uber. Stay safe!

Edit: Whoops sorry, I misread and thought you were at Foggy Bottom. Disregard!

Yeah it was such an abrupt evacuation-type of exercise. Police all outside the metro station and more arriving as I type.

Looks like they were trying to block one of the roads, so avoid the area if you can.
