An attack at the US Capitol complex in Washington DC has left one police officer dead and another in hospital with injuries.

A car crashed into a security barrier before the driver lunged towards the officers with a knife, police said.

The officers opened fire and the suspect was shot dead.

A Capitol Police officer has died after a man rammed a car into two officers at a barricade outside the U.S. Capitol and then emerged wielding a knife. It was the second line-of-duty death this year for a department still struggling to heal from the Jan. 6 insurrection.
