PORTLAND, Ore. (AP) — Authorities say a riot was declared in downtown Portland, Oregon, for the third time this week when the Hatfield Federal Courthouse was attacked early Saturday. KOIN reports shortly before 1 a.m., protesters began throwing rocks at the Federal Courthouse and then firing commercial grade fireworks toward the Justice Center. Some people dragged material and barricades and began to make a fence in the area. Portland police “stayed away from the demonstrators, as there was not an identified life safety risk,” officials said in a release. They said no tear gas was used. Demonstrations in the city following the killing of George Floyd in Minneapolis in late May have grown increasingly violent.
