French police clashed with protesters in Paris marching against racism and alleged police brutality.

The police used teargas to disperse the stone-throwing crowd who tried to hold demonstrations that the BBC reports were banned.

The rally was meant to be held in support of a Black Lives Matter movement sparked by the killing of an unarmed black man in the U.S. last month.

George Floyd died on 25 May after a white police officer knelt on his neck for several minutes as he and his colleagues arrested him.

An onlooker's cell phone recorded the incident showing the 46-year-old black man moaning, "Please, I can't breathe" and "Don't kill me" as the police officer pressed his knee onto Floyd's neck.

After several minutes of the police officer pressing his knee on Floyd’s neck, the victim went silent and was later pronounced dead.

The video quickly went viral on social media, sparking widespread protest from Tuesday afternoon, some of which have deteriorated into chaos.

In the two weeks since his death, protests have spilled beyond the U.S. as countries across the world show solidarity with the demonstrators seeking justice for Floyd’s family.

In Paris, police blocked the anti-racism activists as they tried to stage a march to the Opera.

The march had been banned because of the possible threat to local businesses.
