WATCH: ANTIFA Protesters Attack NBC News Reporter In Charlottesville

Counter-protests against the 'Unite the Right' rally turned aggressive overnight.

Protests designed to mark the one-year anniversary of the "Unite the Right" rally in Charlottesville, Virginia — which left a counter-protester and a state trooper dead — turned violent Saturday night when black-clad members of Antifa joined what was supposed to be a rally for peace.

A group of Antifa protesters went after NBC News reporter Cal Perry as he tried to cover the march, leading to a harrowing scene.

NBC's cameraman on the scene became Antifa's prime target.

The rallies in Charlottesville Saturday were supposed to be about opposing the radicalization and rise of white supremacy, but Antifa showed up early and trouble began almost as soon as the "anti-Fascist" parade stepped off the grounds of the University of Virginia.

Antifa members chanted, "All cops are racist," "cops and the Klan go hand-in-hand," and "last year they came with torches, this year they come with badges."

More clashes are expected Saturday as white supremacist groups rally in Washington, D.C.
