Three people were stabbed and 13 taken into custody when violence erupted at a Ku Klux Klan rally in Anaheim, California, on Saturday, police said.
The Anaheim Police Department on Friday said it was aware of a KKK "walking protest" where members typically pass out literature and hold signs with messages, "which while controversial, are protected by the First Amendment."
A counter-protest was held at the KKK rally in Pearson Park on Saturday.
The rally turned violent when men with Confederate flag patches arrived at the park and clashes broke out between the two sides.
While some protesters were reportedly seen kicking a Klansman, a counter protester said he had been stabbed by a Klansman.
Three counter-protesters were stabbed and two KKK members were stomped on, a spokesperson for the Anaheim Police Department told BuzzFeed News.
A Klansman who was arrested as a suspect in the stabbing told police he "stabbed him in self-defense," the LA Times reported.
A total of 13 people were held in custody; six KKK members and seven counter-protesters, police said.
The decorative end of an American flagpole was used in one of the stabbings, according to police.
All three of the victims were in stable condition, police said.
