Up to a dozen shots were fired outside of the U.S. Capitol this afternoon, sending the Capitol, White House, and Supreme Court into lockdown. The incident reportedly began when a suspect attempted to ram a White House security gate before leading police on a car chase to the Capitol.

The female suspect was reportedly killed outside the Capitol (UPDATE: The Associated Press is reporting that the suspect is alive and in custody), and the lockdown has now been lifted. CNN is also reporting that a child was in the suspect's car.

UPDATE 5:41 PM: The New York Post reports that the driver was Connecticut dental hygienist Miriam Carey.

UPDATE 4:31 PM: Fox News and NBC News have both confirmed that the suspect was killed by police. All gunshots were reportedly fired by police. And Al Hurra has footage from the car chase:

After the shots, Capitol Police quickly issued a Shelter in Place order to Congressional offices:

"SHELTER IN PLACE. Gunshots have been reported on Capitol Hill requiring all occupants in all House Office Buildings to shelter in place. Close, lock and stay away from external doors and windows."

The National Journal has confirmed with U.S. Capitol police that at least one officer is injured, though the exact number or extent of the injury isn't known. ABC News is reporting that the officer was injured during the car chase:

Secret Service pursued a suspect from the White House to the Capitol. One agent in a marked Secret Service vehicle was injured when the car in which he was chasing the suspect was upended by one of the Capitol's electronic barricades as it rose out of the ground.
