The march was peaceful for about an hour, but after protesters arrived at the destination, they started to lit fires in dumpsters and brake windows.
Antifa smash out windows of the Multnomah Building in Portland tonight and throw lit materials inside to set the ground floor on fire. They did this to multiple other buildings over the course of their 80+ days of terror in the city. #PortlandRiots pic.twitter.com/2Q2zO7GVDU

Protests against police brutality and racism have erupted in Portland and other US cities after the death of African American man George Floyd in police custody on 25 May. The Portland protests have since evolved into a nightly battle against the federal forces that President Donald Trump deployed to the city despite the objections of state and local officials.
