Supporters of Trump clash with counter-protestors in US cities
Thousands of supporters of outgoing US President Donald Trump protested in several US cities on Saturday, alleging electoral fraud, and there were violent scuffles with counter-demonstrators.
In Washington DC, more than 20 people were arrested and four people were stabbed, police said.
Trump lost the November 3 election to Joe Biden, but has refused to concede.
The Electoral College, the system which elects US presidents, is due to officially announce Biden's victory on Monday.
Biden, a Democrat, won 306 votes to Trump's 232 in the Electoral College, and gained over seven million more votes than his Republican rival in the popular vote.
In the nation's capital, pro-Trump demonstrators were joined by members of the far-right Proud Boys, dressed in yellow and black, many wearing bullet-proof vests.
Trump caused controversy by saying the group should "stand back and stand by" during a September presidential debate, though he later condemned "all white supremacists".
As night fell, Proud Boys and Antifa counter-demonstrators, mostly separated by police lines, yelled insults at each other. But sporadic violence broke out.
The stabbings took place near downtown, but it was not clear which group those injured belonged to, according to the Washington Post.
Eight people were taken to hospitals, including two police officers, according to CNN.
Make America Great Again (MAGA) protesters, who support Trump, were captured on video tearing down a Black Lives Matter sign from a church, pouring petrol on it and setting it alight.
