Police shoot gunman at entrance to US Capitol
A gunman has been shot in Washington as he tried to enter the US Capitol's visitor centre with a gun.
He drew a weapon during a routine security screening in the visitors' centre of the sprawling Capitol complex, police said.
It is not believed to have been a terror attack.
The man was later taken into custody.
Both the White House and Capital complex were put on lockdown as events unfolded.
Initial reports suggested an officer had been shot, but Capitol Police Chief Matthew Verderosa said that wasn't the case.
It is understood a female bystander suffered minor injuries when police fired at the suspect.
Mr Verderosa said the suspect pulled out "what appeared to be a weapon" and an officer shot him.
The suspect is currently undergoing surgery and his condition is not known.
A weapon was recovered at the scene.
The identity of the suspect was not given, but Mr Verderosa told a press conference the "suspect is known" to the Capitol Police.
He added that there is "no reason to believe this is anything more than a criminal act."
Staffers, reporters and others were told to "shelter in place" and not allowed to leave their offices.
Congress is currently on recess for Easter and politicians are back in their constituencies.
