Car Rams US Capitol Barricade; One Officer and Driver Dead

Authorities investigate at the scene after a man rammed a car into two officers at the barricade on Capitol Hill in Washington Friday

Two U.S Capitol Police officers were injured Friday when a driver slammed a vehicle into a barricade outside the U.S. Capitol.

President Joe Biden has ordered that U.S. flags at the White House be lowered to half-staff until April 6 in honour of a U.S. Capitol Police officer who was killed on Friday after a man rammed a auto into a security checkpoint. The driver of the auto was shot by police and taken to a hospital in critical condition.

Citing four law enforcement officials, NBC News later identified the suspect as 25-year-old Noad Green of IN, though he may have been living recently IN Virginia.

Green described himself as a follower of the Nation of Islam and its founder, Louis Farrakhan, and spoke of going through a hard time where he leaned on his faith, according to recent messages posted online that have since been taken down.

Pittman did not release the identity of the suspect.

Mr. Biden says he and first lady Jill Biden are heartbroken over the death of officer William Evans, an 18-year veteran of the Capitol Police force. "We extend condolences to the family of the fallen Capitol police officer and wish a full recovery to the second officer". It comes as the Washington region remains on edge almost three months after a mob of armed insurrectionists stormed the Capitol as Congress was voting to certify Joe Biden's presidential win.

Police block a street near the US Capitol on Friday after a vehicle drove into officers at the complex in Washington.

"This has been an extremely hard time for U.S. Capitol Police", Pittman said at a news conference on Friday afternoon, noting the attack underscores that the Capitol Hill remains a potential target for violence.

Earlier on Friday afternoon, witnesses reported a hail of gunfire outside the north barricade USA national legislature. They further added that the suspect did not appear to wrestle with the police officers.

"Capitol Police officers heroically defended our Capitol when it was under attack yet again, and I am deeply grateful for their service", Moulton said.

NBC News and the New York Times identified the suspect in the attack as Noah R. Green, 25. "We need to obviously understand the motivation behind this senseless act, so the Metropolitan Police Department will certainly be doing that".

The incident began shortly after 1 p.m. ET, when the Capitol was placed on lockdown "due to an external security threat".

A helicopter landed on the Capitol grounds and the police were loaded on board to be taken to a hospital. He said there did not appear to be any indication the attack was terrorism-related, but the investigation is ongoing and investigators will continue to see if there's any links to terrorism. The Capitol complex was locked down after the shooting.

The Capitol complex has been on high alert since the January 6 attack by former President Donald Trump's supporters, which left five people dead.
