At least 16 people have been arrested on charges of assaulting officers, obstruction and failure to disperse, police said. Three officers have been injured, including one who was hospitalized with a leg injury caused by an explosive. Police described the protests as riots.
The other two officers were treated and have returned to duty, police said.
Seattle has been the scene of protests over police brutality and systemic racism, including in a six-block area controlled by protesters after police abandoned their precinct — the Capitol Hill Organized Protest or Capital Hill Autonomous Zone.
