PORTLAND, Ore. – A few dozen people in Portland participated in a “Million Mask March" Sunday night, one day after an anti-fascist demonstration and rally in downtown Portland.

The Million Mask March in Portland started around 5 p.m. near waterfront park. At 5 p.m., a little more than a dozen people milled about the Salmon Street fountain. At about 6 p.m., a few dozen began marching through downtown Portland before gathering for a rally at Jamison Square. Protesters began marching through downtown again at 6:30 p.m.

Portland police tweeted that protesters were obeying all laws.

The Million Mask March in Portland is part of a worldwide annual protest that occurs on Guy Fawkes Day, which is Nov. 5.

Many of the marchers identify with the Anonymous movement. The organization’s website says 800 cities worldwide have planned protests this year.

Six people were arrested during the march in 2016, when the protest blocked traffic on Interstate 5 in Southeast Portland.

Traffic could be impacted during the 2017 march in downtown Portland. Since Mayor Ted Wheeler took office on Jan. 1, no protesters have been allowed to march onto freeways in Portland.

The Portland Police Bureau said it had personnel prepared to respond to the event if there is a perceived threat, but the bureau was not aware of any specific threats regarding the event.

At least 100 Antifa demonstrators rallied in Portland Saturday afternoon. The demonstrators held a moment of silence for Florida teenager Trayvon Martin, who was killed by George Zimmerman in 2012, and clashed with Joey Gibson, leader of the right-wing group Patriot Prayer, who showed up at the rally.
