The U.S. Capitol was temporarily locked down  Thursday afternoon after a report of shots fired at the Capitol Building.

If you are traveling through the area — on foot, by car, bus or rail — be aware that there likely will be an increased police presence and street closures.

D.C. police have closed Second Street and Maryland Avenue NE and Constitution Avenue NE, according to the department’s official Twitter account.

The Post’s Dana Hedgpeth reports that Metro Transit Police are adding additional officers at Capitol South and Union Station, two of the stations closest to the Capitol. But the two stations remain open at this time, according to Dan Stessel, a Metro spokesman.

The shots fired appeared to be on the north side of the Capitol, closer to Union Station.
