Police tried to keep the two sides apart as protesters chanted and hurled insults at each other. Authorities set up a security perimeter around a waterfront park and officers frisked attendees and confiscated flag poles and other potential weapons.
Clashes after similar protests in the northwestern US city in June sent four people including a police officer to the hospital.
Among the right-wing marchers, some of whom wore body armor and carried shields, were members of the Patriot Prayer group founded by Joey Gibson, a conservative Republican who is running for the US Senate in November’s mid-term elections.
They were opposed by counter-protesters, some dressed in black with face masks, who shouted anti-Nazi slogans.
Gibson told supporters they had to be united.
“It’s not even about those punks over there,” he said of the counter-protesters, in a video of his speech shared on social media. “They’re just an obstacle. We’ve got to get them out of the way so we can truly march the streets with thousands of people, so that we can actually come together with liberals.”
Using a Portland Police Bureau sound truck, an officer told people gathered in and around Tom McCall Waterfront Park that no firearms were allowed, and that officers would use reasonable force to curtail any “assaultive behavior.”
Protesters at one intersection were seen throwing projectiles including rocks and bottles, the officer said. He called on people there to disperse, adding that failure to do so could result in arrest, citation, or being the subject of "the use of riot control agents or impact weapons."
Police said on Twitter that they had seized multiple items that could be used as weapons, and were "observing people in helmets and protective padding."
Meanwhile, due to the events at the park, officers were only responding to emergency service calls, the bureau said.
Helicopters flew overhead but elsewhere in Portland life continued much as normal. Just blocks from the waterfront standoff, the city's quirky Saturday Market was in full flow with stalls offering artwork alongside handmade herbal balms, psychedelic wind chimes, and custom henna.
