The United States Capitol was placed under lockdown on Friday due to an "exterior security threat" after a car rammed two police officers.

The United States Capitol Police (USCP) said two officers were injured after a car rammed into them. One officer later died of his injuries.

Reports said the suspect exited his car wielding a knife and was shot by the USCP, dying of his injuries.

Capitol Police outside of the building were seen tending to at least one person on the ground, with at least two stretchers rolled out and large amounts of law enforcement and first responder activity, according to Fox News.

At least two people were pushed on separate stretchers into two separate ambulances, which have left the scene.

Fox News reported that security officials believe the suspect was a "lone wolf" and was not connected to any other group.
