George Floyd protests: Who are Boogaloo Bois, antifa and Proud Boys?
More than three weeks since the death of George Floyd, anti-racism protests are continuing across the US. While in many cases peaceful, the protests have also featured scenes of police brutality, looting and violence. Politicians, law enforcement and commentators on the left and right have accused a number of fringe groups of encouraging and participating in acts of violence. BBC News has been examining these groups on social media platforms.
