Federal agents, deployed by President Trump, have fired tear gas into crowds of demonstrators. Homeland Security Secretary Chad Wolf previously called the protesters a "violent mob".

Late on Saturday, protesters were seen dismantling a fence around the federal courthouse, hours after it was put up.

The US Attorney's office in Oregon said on Twitter that the fence aimed to "de-escalate tensions" between protesters and law enforcement officials and asked people to leave it alone.

Officers declared a riot outside the Portland Police Association building. It was set on fire.
