THE Prime Minister has called for a “peaceful and orderly transfer of power” in the United States after violent crowds protesting Joe Biden's presidential win stormed the Capitol, leading to four deaths.

Protesters interrupted politicians’ formal approval of Mr Biden’s presidential election win, where four people have died and two suspected explosive devices were made safe by the FBI.

In addition to the woman shot by police, three others died as a result of "medical emergencies".

In a video on social media, Donald Trump told protesters that they “have to go home now” while also claiming that “this was a fraudulent election” before being banned from Facebook and Twitter.

The site had earlier removed the retweet, like and reply functions on a video in which Mr Trump addressed his supporters who had clashed with police in Washington DC forcing a lockdown at the US Capitol building.

In chaotic scenes, supporters of President Mr Trump breached barricades and staged an occupation of the building in Washington DC on Wednesday.

Protesters clashed with police, tear gas was dispersed and one woman later died after being shot inside the US Capitol.

Demonstrators forced their way inside after a rally was held near the White House where Mr Trump encouraged them to march on Capitol Hill.

A nighttime curfew is now in place in Washington DC.

Boris Johnson labelled the scenes as “disgraceful”.

He tweeted: “The United States stands for democracy around the world and it is now vital that there should be a peaceful and orderly transfer of power.”

His comments followed condemnation from a host of British politicians from all parties who described the scenes in Washington as “profoundly shocking” and “utterly horrifying”.

Labour leader Sir Keir Starmer called them “horrendous”, tweeting: “These are not ‘protesters’ – this a direct attack on democracy and legislators carrying out the will of the American people.”

Foreign Secretary Dominic Raab tweeted: “The US rightly takes great pride in its democracy, and there can be no justification for these violent attempts to frustrate the lawful and proper transition of power.”

Twitter has locked Donald Trump’s account for the first time and demanded he remove tweets excusing violence as it threatened him with “permanent suspension” from the platform.

In the video, the president told protesters that they “have to go home now”, adding “we don’t want anybody hurt”, but he also claimed that “this was a fraudulent election”.

“As a result of the unprecedented and ongoing violent situation in Washington, DC, we have required the removal of three @realDonaldTrump Tweets that were posted earlier today for repeated and severe violations of our Civic Integrity policy,” Twitter Safety posted.

“This means that the account of @realDonaldTrump will be locked for 12 hours following the removal of these Tweets. If the Tweets are not removed, the account will remain locked.

“Future violations of the Twitter Rules, including our Civic Integrity or Violent Threats policies, will result in permanent suspension of the @realDonaldTrump
account.”

Twitter had earlier added a warning to the video, which read: “This claim of election fraud is disputed, and this tweet can’t be replied to, retweeted, or liked due to a risk of violence.”

Facebook’s vice president of integrity Guy Rosen, meanwhile, tweeted that Mr Trump’s video had been removed entirely from their platform.

“This is an emergency situation and we are taking appropriate emergency measures, including removing President Trump’s video,” he tweeted.

“We removed it because on balance we believe it contributes to rather than diminishes the risk of ongoing violence.”
