Police officer killed at the Capitol honoured with police procession

Police in Washington DC have lined the streets in a procession for police officer William Evans, who was killed in an attack on the Capitol building yesterday.

The suspect, who rammed his car into officers defending a barricade, was shot dead on the scene.

The attack has reignited the debate over the challenge to secure Capitol Hill, less than three months after it was stormed by a violent mob in January.
