Police in Washington, DC, were investigating an “active bomb threat” on Capitol Hill Thursday, with congressional offices evacuated over fears of a possible explosive-laden pickup truck.
“The USCP is responding to a suspicious vehicle near the Library of Congress,” the Capitol Police tweeted just before 10 a.m. of the historic building near the Capitol and the Supreme Court.
“Please stay away from this area … This is an active bomb threat investigation,” the force said.
CNN’s Whitney Wild said that a man was inside the suspicious truck and police were “sending negotiators to engage with” him.
Snipers were also being sent as officers tried to work out if the man in the truck was holding a detonator, sources told The Associated Press.
Images showed a huge police response, with the FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives also responding.
Both the Senate and House of Representatives are currently on recess, but staffers are working in the Capitol complex.
Police evacuated congressional staff offices nearby, encouraging people to remain calm and use the underground tunnels if necessary to evacuate away from the area.
The White House said it was monitoring the situation and being briefed by law enforcement.
The incident comes months after a pipe bomb was left at the headquarters of the Democratic National Committee and the Republican National Committee in Washington a day before thousands of pro-Trump rioters stormed the U.S. Capitol on Jan. 6.
In April, a man rammed a car into barriers at Capitol, killing an officer before the attacker was shot and killed.
