At least eight counter protesters at a "white power" rally Saturday at Georgia's Stone Mountain were arrested as they clashed with police while trying to get inside the park.

The Atlanta Journal-Constitution reported the protesters were dressed in black and chanting, "Hey hey, ho ho, the KKK has got to go."

Hundreds are involved in the counter protest, WSB-TV reported, and police in riot gear continue to work to keep the peace.

AJC reported the counter-protesters were arrested after refusing to take off their masks. It is illegal to protest in Georgia while wearing a mask.

One protester was seen spraying a Georgia State Patrol officer with pepper spray. Others tussled with police.

The rally, dubbed a "Pro White March up Stone Mountain," according to the group's Facebook page, was expected to attract as many as 2,000 white extremists on the Confederate Memorial Day weekend. The rally was to be followed by a "Pro White concert."

One of the rally attendees, Kim Beasley, of Birmingham was wearing a T-shirt that read, "Heritage Not Hate." She told the AJC that she isn't "politically correct," and she isn't a white supremacist.

"We don't believe in carrying these flags for racist reasons," she said. "We don't believe the Civil War was over racism. It was over tyranny."

A heavy police presence at the rally worked to keep the event contained to a parking lot away from the main part of the Stone Mountain Park, according to reports. Some roads were closed to keep the rally away from other guests and the counter protesters.
