At least three men have been stabbed at a Ku Klux Klan rally near Disneyland in southern California.
One of those is believed to be in a critical condition after the brawl in the city of Anaheim.
It is understood a KKK rally was organised on Facebook and a number of protestors went along as well to voice their views.
13 people, including KKK members and rival demonstrators, have been arrested.
Members of the KKK cried the stabbing had been in self defence as they were led away in handcuffs.
