The US will designate the anti-fascist group Antifa a terrorist organisation, President Donald Trump says.
The president accused Antifa of starting riots that stemmed from protests over George Floyd’s death.
Mr Floyd, a black man, died in police custody earlier this week, reigniting anger at police treatment of African-Americans.
Protests over his death have turned violent, prompting major cities to impose curfews.
On Saturday, Minnesota’s Democratic Governor Tim Walz suggested that foreign influences, white supremacists and drug cartels were behind the violence, giving few other details.
