Gun shots have been fired on Capitol Hill, according to police. 

The Capitol was on shutdown following the shooting with the U.S. Capitol Police sending the following email to those on the Hill, according to Politico:

"Close, lock and stay away from external doors and windows. Take annunciators, Go Kits and escape hoods; and move to the innermost part of the office away from external doors or windows. If you are not in your office, take shelter in the nearest office, check in with your OEC and wait for USCP to clear the incident. No one will be permitted to enter or exit the building until directed by USCP. All staff should monitor the situation. Further information will be provided as it becomes available.”

A capitol police officer has been reportedly injured. The shutdown of the Capitol was lifted minutes ago.

According to the MSNBC, the incident began at The White House around 2:15 p.m. EST when a female driver of a black car tried to ram through one of the check points at one of the security gates. Secret service officers then pursued the car and the driver then drove towards the Capitol and began shooting near First St. and Constitution Ave.

There are reports that the female driver was shot by officers in an exchange of fire once she got to the Capitol and began shooting, but this has not been confirmed.
