Police officers fired tear gas and arrested protesters in Portland on Saturday after nearly 200 hundred people gathered outside the US District Courthouse in support of the Black Lives Matter movement.
Demonstrators could be seen regrouping after being dispersed by the officers, who then again used tear gas.
At least one person was taken to hospital after suffering a head injury from what was is believed to be a crowd control munition. He could be seen being carried away by demonstrators.
After six weeks of peaceful BLM demonstrations, Portland has witnessed the second consecutive night of clashes between police and BLM activists.
