(Reuters) - Anti-fascist and right-wing activists clashed in Portland, Oregon on Saturday night as violence broke out during a march in support of a conservative Republican candidate for the U.S. Senate, media reported.

Scuffles broke out after anti-fascists pelted marchers from the right-wing Patriot Prayer group with eggs, water bottles and firecrackers, the Oregonian newspaper reported. The Patriot Prayer group’s founder Joey Gibson is running for the Senate.

Police made a handful of arrests from both sides, and officers seized utility knives, pepper spray and clubs, according to the newspaper.

A spokesperson for the Portland police could not be immediately reached for comment.
