US Capitol on lockdown after car runs into two police officers

The US Capitol building and surrounding streets in Washington DC are in lockdown after police warned of an “external security threat”.

A BBC new report states that Capitol police have a suspect in custody after someone “rammed a vehicle” into two officers.

“The suspect and both officers have been taken to hospital,” said police.

Video from outside the Capitol shows a vehicle that appears to have slammed into a barricade surrounding the complex.
