Washington riots: Watch as demonstrators storm Capitol Hill

Rioters damaged building, climbed walls and forced their way in through broken windows

Supporters of US President Donald Trump stormed the US Capitol in Washington on Wednesday, forcing a lockdown as Congress debated certifying the presidential election results.

The chaotic day culminated in an armed stand-off between law enforcement officers and the agitators in the inner chamber, where politicians had taken cover.

Two women and two men died during the violence.
