 An exchange of gunfire in downtown Portland has occurred after protests by rebel far-right and left-wing groups led to clashes and nobody was hurt when a man fired a handgun at demonstrators. The shooter was later arrested. The shooting occurred after an earlier clash in northeast Portland saw right-wing protesters using paintball guns in fireworks against left-wing anti-fascist counter-protestors. Now Portland has been a magnet for clashes between political extremists since last year.
