Prime ministers and presidents around the world have urged US president Donald Trump and his supporters to accept the result of November’s presidential election and accede to a peaceful transition of power. President-elect Joe Biden’s administration is set to be inaugurated in 14 days.

“Inflammatory words turn into violent acts – on the steps of the Reichstag, and now in the #Capitol,” Germany’s foreign minister, Heiko Maas, tweeted, as Trump loyalists led a violent assault on the heart of the American republic.

Maas urged Trump and his supporters to “finally accept the decision of the American voters and stop trampling democracy”.

“The outcome of this democratic election must be respected,” Jens Stoltenberg, the Nato secretary general and former Norwegian prime minister, tweeted on Wednesday evening after US president-elect Joe Biden condemned “this godawful display” and warned: “The world is watching”.
