Protesters have pulled down a statute of Christopher Columbus outside the Minnesota State Capitol.
A rope was thrown around the 3m-tall bronze statue on Wednesday afternoon and it was pulled off its stone pedestal.
The protesters, including Dakota and Ojibwe Indians, said they consider Columbus a symbol of genocide against Native Americans.
They said they had tried many times to remove it through the political process, but without success.
State Patrol troopers in helmets, who provide security in the Capitol complex, stood by at a distance but did not try to stop the protesters, who celebrated afterwards with Native American singing and drumming.
The troopers eventually formed a line to protect the toppled statue so it could be taken away.
The protest followed a similar incident on Tuesday night in Richmond, Virginia, and another in Boston, where a statue of Columbus located in Waterfront Park in was removed after being beheaded.
In the UK, London mayor Sadiq Khan posted video on Twitter on Tuesday of officials in East London removing a statue of 18th-century merchant and slave owner Robert Milligan from its place in the city’s docklands.
It came a day after Mr Khan announced that more statues of imperialist figures could be removed from Britain’s streets after protesters in Bristol knocked down a monument to slave trader Edward Colston on Sunday.
“It’s a sad truth that much of our wealth was derived from the slave trade – but this does not have to be celebrated in our public spaces,” he wrote on Twitter.
The removal of Milligan’s statue came even before a new commission announced by Mr Khan got under way.
The commission will review statues, murals, street art, street names and other memorials and consider which legacies should be celebrated, the mayor’s office said.
Joe Biggs, mayor of London’s Tower Hamlets borough, following the toppling of a statue of slave trader by demonstrators in the city of Bristol on Sunday, said: “We’ve acted quickly to both ensure public safety and respond to the concerns of our residents, which I share.”
The moves have revived calls for Oxford University to remove a statue of Cecil Rhodes, a Victorian imperialist in southern Africa who made a fortune from mines and endowed Oxford University’s Rhodes scholarships.
Several hundred supporters of the Rhodes Must Fall group gathered near the statue at the university’s college on Tuesday, chanting “Take it down” before holding a silent sit-down vigil in the street to memorialise George Floyd.
Oxford city officials urged the college to apply for permission to remove the statue so that it could be placed in a museum.
British Prime Minister Boris Johnson has acknowledged that it was “a cold reality” that people of colour in Britain experienced discrimination, but said those who attacked police or desecrated public monuments should face “the full force of the law”.
Some historical figures have complex legacies.
At weekend protests in London, demonstrators scrawled “was a racist” on a statue of Winston Churchill.
Britain’s wartime prime minister is revered as the man who led the country to victory against Nazi Germany. But he was also a staunch defender of the British Empire and expressed racist views.
Mr Khan suggested Churchill’s statue should stay up.
“Nobody’s perfect, whether it’s Churchill, whether it’s Gandhi, whether it’s Malcolm X,” he told the BBC, adding that schools should teach children about historical figures “warts and all”.
“But there are some statues that are quite clear-cut,” Mr Khan said. “Slavers are quite clear-cut in my view, plantation owners are quite clear-cut.”
