The US Capitol building is in lockdown after a vehicle reportedly slammed into the security barriers surrounding the complex, police say.
Capitol Police said that a suspect is in custody after reports that someone “rammed a vehicle” into two officers.
The suspect and the two officers have been taken to hospital, police said.
The Capitol and surrounding streets in Washington DC are in lockdown after police warned of an “external security threat”.
Footage of the scene has shown a helicopter flying overhead and what appeared to be two people on stretchers being moved into ambulances.
Onlookers have been told to clear the area.
The reports come nearly three months after the fatal 6 January riots at the Capitol.
