A group of activists has claimed America’s “stolen land” is a holiday in and of itself.
In a statement on Twitter, Black Lives Matter said the Thanksgiving holiday was a “symbolic choice to colonise” Native Americans.
Earlier on Friday, a Black Lives Matter protester was arrested during a protest at Atlanta.
Dozens of protesters gathered outside the Georgia state office building in the state capital, waving signs and chanting against police brutality.
President Donald Trump – who is celebrating his 79th birthday – is due to visit Alabama and Georgia over the next few days.

Below are the social media hashtags #BlackLivesMatter and #ThanksgivingDeclaration
The hashtag BlackLivesMatter is a reference to an event in August when protesters were targeted by New York police during a rally.
