Shots were fired outside the US Capitol building on Thursday triggering a lockdown and a massive security operation.

The shots were heard after a woman tried to ram a car into the White House gate.  Secret service chased the woman as the police exchanged shots with her.

The suspect — who sources said had a child in the car — was shot and killed, and a shelter-in-place order was lifted. At least one Capitol Police officer was injured during the pursuit.

Police considered the incident as isolated and has no terror link, with Capitol Police Chief Kim Dine said:
"This appears to be an isolated incident."
"Both scenes are under control," Dine added.

The incident started when the woman in a black car tried to breach White House security at 15th St. and E, law-enforcement sources said.
She did not get through and was chased at high speeds for about 12 blocks, the sources said.

Her car hit a Capitol Police vehicle and then crashed into barricades a few blocks away, Dine said.

President Barack Obama was briefed about the harrowing incident, which came in the midst of the government shutdown that has created a tense atmosphere on Capitol Hill.

The FBI responded to the scene, and a helicopter landed in front of the Capitol to medevac the injured officer.

A message from the Capitol Police ordered anyone in a House office to "shelter in place," but that order was lifted a short time later.
