Multiple stabbings were reported at a demonstration organized by the Traditionalist Worker Party at the Capitol on Sunday as demonstrators clashed with protesters in what the Sacramento Fire Department has called a “mass casualty incident.”

According to Sacramento Fire Department public information officer Chris Harvey, seven individuals were transported to the hospital, while at least two have critical stab wounds.

Harvey said as of 2 p.m., most of the protesters had left the scene.

The Traditionalist Worker Party, which has been linked to white supremacy groups, describes itself on its website as “America’s first political party created by and for working families,” and states its mission is “defending faith, family, and folk against the politicians and oligarchs who are running America into the ground.”

The Traditional Worker Party promoted the demonstration at the Capitol on its Facebook page in the weeks leading up to today’s event.

Antifa Sacramento, a local chapter of the Anti-Fascist Action Network, rallied support for a counter-protest through social media.

When asked to comment on the violent clash at the Capitol, an Antifa Sacramento member said “We stopped the nazi rally.”

Antifa Sacramento has organized a fundraiser for those injured during the protest.
