Black Lives Matter has called on Christmas shoppers to boycott white companies as part of "Black Xmas".
The Black Lives Matter Global Network announced on social media there should be no spending at companies owned by white people between Black Friday on November 26 and New Year's Day.
It encouraged people to "buy exclusively from Black-owned businesses", adding "we're dreaming of a #Blackxmas". Black Xmas began in 2014 after John Crawford, a black man, was fatally shot in an Ohio Walmart store.
The group also posted on its website: "Black Friday sales are being rolled out weeks in advance of Thanksgiving and, at every turn, white-supremacist-capitalism is telling us to spend our money on things that we don't need, to reap profits for corporations.
"Let's harness our economic power to disrupt white-supremacist-capitalism and build Black community."
The move prompted criticism from some social media users, who said it was racist and segregating. Others praised the move and asked for recommendations of black-owned firms to support.
