A march by a neo-Nazi group outside Californiaâ€™s Capitol in Sacramento descended into chaos on Sunday after the demonstrators were attacked by groups of counter-protesters.
Sacramento authorities said multiple people were stabbed in the melee, and described the situation as a â€œmass casualty incident.â€
In a statement posted on Twitter, the Sacramento Fire Department said five people were hospitalized, â€œsome with critical trauma stab wounds.â€ No arrests have been reported.
The Sacramento Bee reported that the clashes involved â€œaround 150 anarchists and â€˜anti-fascistâ€™ protestors and about 25 neo-Nazis.â€
Video footage posted on social media showed masked counter-protesters clad in black wielding large wooden sticks and other makeshift weapons. Several people were shown being knocked down and beaten.
Photos from the scene also showed blood spatters on the ground and areas marked off with crime scene tape.
â€œItâ€™s a highly volatile situation,â€ Sacramento Police Chief Sam Somers said, according to theSacramento Bee. He said other skinhead rallies had been held at the Capitol, but â€œthis time the the anarchists have taken a much more aggressive stance to wreak havoc on the city.â€
The neo-Nazi event was organized by a group called the Traditionalist Workers Party, and a link posted on the groupâ€™s Facebook page called it a protest â€œagainst globalization and in defense of the right to free expression.â€ The group said it had obtained the necessary permits to march near the Capitol.
The Los Angeles Times reported that counter-protests were organized on social media. The Traditionalist Workers Party seemed to recognize the threat of violence ahead of the march. The groupâ€™s Facebook page linked to a post that described the demonstration as a â€œmarch into the infernoâ€ and referred to the possibility that a â€œmobâ€ of opposition â€œmay outnumber our men up to 10 to 1.â€
According to the Southern Poverty Law Center (SPLC), which tracks extremist groups in the US, the Traditionalist Workers Party formed in January 2015 as as the political wing of the Traditionalist Youth Network, â€œan identitarian-inspired umbrella group that aims to indoctrinate high school and college students into white nationalism.â€ The SPLC described the Traditionalist Youth Network as â€œvirulently racist and anti-Semitic.â€
