Bomb threat detected near US Capitol

Police are investigating an “active bomb threat” near the US Capitol in Washington DC.

US Capitol Police said they were negotiating with the driver of a suspicious vehicle near the Library of Congress, across the street from the Capitol building and Supreme Court.

The motives of the driver remain unknown, they said.

Several office buildings have been evacuated. Congress is on recess, but some staff are working in the Capitol.

Some members of staff on Capitol Hill were originally told to remain in place and shelter in offices.
