Police officer dies after being injured during riots in US Capitol
A police officer has died after being injured as Donald Trump supporters stormed the US Capitol building.
Capitol Police officer Brian Sicknick was injured while confronting protesters, the force said in statement.
He collapsed when he returned to his divisional office and was taken to hospital, where he died from his injuries, they added.
It brings the death toll from the riot to five.
Wednesday's breach of the legislative building came as lawmakers were certifying the victory of President-elect Joe Biden.
Metropolitan homicide officials will investigate the death of Mr Sicknick, who joined the Capitol Police in 2008, along with the Capitol force and its federal partners.
Mr Trump, who initially praised his supporters, later condemned the violence, saying the rioters had defiled the seat of American democracy and must be held accountable.
A woman demonstrator, Ashli Babbitt, was fatally shot by authorities, and three people died from medical emergencies.
After a rally where Mr Trump exhorted his supporters to "fight" to overturn the November 3 election he lost, hundreds of them stormed the Capitol on Wednesday.
They forced senators and members of the House of Representatives to evacuate as they smashed windows and looted.
As Democratic leaders demanded he is ousted, Mr Trump came closer to a formal concession.
He acknowledging in a video released on Thursday evening that a "new administration" would be sworn in on January 20 and vowed to ensure a "smooth transition” of power.
