America hasn't witnessed civil unrest like this since the late 1960s.

There have been protests and rioting in cities across the US, following the death of a black man, George Floyd, in police custody in Minneapolis.

In Atlanta, at the height of the demonstrations, the rapper Killer Mike - the son of an Atlanta policeman - addressed protesters calling for calm and urging them to go home.

His speech went viral around the world.
