Protests marking the one-year anniversary of the "Unite the Right" rally in Charlottesville, Virginia, turned violent Saturday night when Antifa protesters overran a mostly peaceful demonstration.

What happened?

A group of protesters cornered and attacked NBC News reporter Cal Perry, even knocking his cameraman's equipment down. Fortunately, the violence was mostly captured on camera.

"By design, last night’s Antifa led rally/protest in #Charlottesville got a bit rough and tumble," Perry wrote on Twitter after the mayhem.

He added that Sunday's demonstrations will also be led by Antifa.

Saturday's rallies were expected to be largely peaceful demonstrations against white supremacy and racism. That quickly changed when violent Antifa protesters hit the street after dark. Not only did they show violence toward media, but they also targeted police.

The violence became so tense that the University of Virginia Hospital was placed on lockdown and employees were told to remain inside the building while the protests were ongoing.

Unfortunately, more violence is expected later on Sunday, where demonstrators also plan to protest outside the White House.

Was that it?

Antifa violence was not exclusive to Charlottesville on Saturday. During demonstrations in Toronto, Antifa attacked Toronto Sun photographer Stan Behal.
