Several people were hurt Saturday in violent clashes in downtown Portland, Oregon, between far-right Proud Boys demonstrators and anti-fascist counter protesters.

Skirmishes erupted as some people had taken to the streets to wave rainbow flags commemorating Pride Month while Proud Boys and members of the #HimToo movement held aloft banners and signs touting President Donald Trump.

Some protesters hurled “vegan” milkshakes while others threw “milkshakes” with water and quick-drying cement, according to local police. Several demonstrators were also throwing eggs and water bottles.

Police said in a statement that “there were multiple assaults reported, as well as projectiles thrown at demonstrators and officers. There were also reports of pepper spray and bear spray being used by people in the crowd.”
