Curfews have been ordered in cities across the US in an attempt to stem the violent clashes between protesters and police over the death of George Floyd.
BBC News reports widespread demonstrations have taken place, with riot police using tear gas and rubber bullets after their vehicles were set alight in several cities.
US President Donald Trump blamed "looters and anarchists" for the violence.
Floyd, a 46-year-old African American, was killed while in police custody in Minneapolis.
Former policeman Derek Chauvin, 44 and white, has been charged with his murder and is due to appear in court.
In footage that went viral online, Chauvin can be seen kneeling on Floyd's neck for several minutes.
Floyd repeatedly says that he is unable to breathe.
Three other officers present at the time have also since been sacked.
