A gunman drove his car into a barricade near the US Capitol building, before opening fire into the air and then shooting himself, police say.
While he was getting out of the vehicle in Washington DC, it is said to have burst into flames.
Nobody else was hurt in the incident, which happened at about 4am local time, officers explained.
Capitol Police said in a statement: ‘At this time, it does not appear the man was targeting any Members of Congress, who are on recess, and it does not appear officers fired their weapons.
‘Our investigators are looking into the man’s background.’
The force added: ‘When our officers heard the sound of gunfire, they immediately responded and were approaching the man when he shot himself.’
Pictures show the burnt out car being removed to reveal a charred pavement near the barricade.
It comes as law enforcement authorities across the country are facing increasing threats amid warnings about the possible attacks on government buildings, after the FBI searched former President Donald Trump’s Mar-a-Lago estate.
The attack is reminiscent of an incident when a man drove a vehicle into two Capitol Police officers at a checkpoint in April 2021, killing an 18-year veteran of the force.
Many on Capitol Hill remain on edge after supporters of the then-president Trump stormed the building on January 6 last year.
The man’s vehicle is said to have hit the barricade at East Capitol Street and Second Street, before he fired ‘several shots’ into the air on East Capitol Street.
The gunman, who was later pronounced dead, has not been identified.
