Multiple people were stabbed Sunday at a neo-Nazi event outside of the California state Capitol in Sacramento after clashes erupted between the groups and counterprotesters, the Los Angeles Times reported.

The public information officer for the California Highway Patrol’s Capitol Protection Section, which has jurisdiction over the capitol grounds, told the Times that at least seven people were stabbed. Some are critically injured

The officer, George Grenada, said that hundreds of counterprotesters were waiting for the neo-Nazi groups and immediately swarmed when about 30 people showed up for the scheduled event.

“I don’t think there was any verbal exchange, just full on fight,” he said.

The Traditionalist Worker Party was set to hold a rally outside of the Capitol building, ABC 10 reported, and was greatly outnumbered by a large group of counterprotesters, some armed with bats.

The Southern Poverty Law Center, which tracks hate groups, said the party is the political offshoot of the Traditionalist Youth Network, which "aims to indoctrinate high school and college students into white nationalism."

Fox News reported that several other white supremacist groups were set to attend the rally, including the Ku Klux Klan.

Reports on social media showed police blocking off the area after the violence subsided. There haven't been any arrests.
