A motorist mowed down two cops outside the US Capitol and was shot dead by police after smashing into a barrier and emerging with a knife on Friday afternoon, according to officials and reports.
All three were taken to the hospital — with the suspect in custody — as the building was placed on lockdown following the chaos that erupted around 1 p.m.
The unidentified suspect later died, according to ABC News, which also said one of the cops was in critical condition.
The incident took place at a vehicle checkpoint on the north side of the Capitol along Constitution Avenue in Washington DC, police said.
Sources told NBC News that the driver got out of the car with a knife after hitting the officers, then was shot.
