U.S. Capitol on lockdown after security incident

One officer killed after driver rams into US Capitol barricade

Members of Congress, who were in their home districts for the Easter and Passover holidays, once again mourned the loss of a Capitol Police officer, a member of the force that protects them when they're in Washington. At least one of the officers was seriously injured, the officials said.

Streets surrounding the US Capitol and congressional office buildings were locked down, with dozens of police cars - marked and unmarked - raced toward America's legislative seat.

This ramming incident comes almost three months after insurrectionists stormed the Capitol as Congress was voting to certify Joe Biden's presidential win.

One U.S. Capitol Police officer is dead and another is hospitalized with injuries after an apparent attack at a Capitol checkpoint, in which a man rammed his vehicle into officers and lunged at them with a knife, police said. The officer's identity was not released. Authorities said that there was no longer an ongoing threat and that the attack did not appear to be related to terrorism.

She says the suspect then exited the vehicle with a knife and lunged at the officers. The suspect was shot and died at the hospital.

A spokesperson with the police department said the driver rammed the vehicle into the officers shortly after 1 p.m. ET. The suspect died at a hospital.

The security checkpoint is typically used by senators and staff on weekdays, but lawmakers are away for recess. Fencing that prevented vehicular traffic near that area was recently removed.

Evans is the seventh Capitol Police member to die in the line of duty in the department's history, according to the Officer Down Memorial Page, which tracks deaths of law enforcement.

Update: Law enforcement sources have told ABC News that the suspect is dead.

The police also notified road closures "due to the external security threat at the North Barricade of the US Capitol".

Officers shot the driver after he got out of his vehicle with a knife and ran "aggressively toward officers", she added. But the hallways were mostly empty despite the chaos outside. Authorities have begun only in the past couple of weeks to remove the outer ring of high, razor-wire-topped fencing erected around the sprawling Capitol complex after the January 6 rampage.

Other footage showed National Guard troops marching toward the Capitol. It was the second line-of-duty death this year for a department still struggling to heal from the January 6 insurrection.

The officials could not discuss the matter publicly and spoke to the AP on condition of anonymity.
