A bystander was fatally shot after security members at the demonstration confronted a man who was running toward the crowd with an AR-15-style rifle, the police said.

An estimated 10,000 people were peacefully marching in downtown Salt Lake City when shots rang out, killing an "innocent bystander," police said.

The shooting at Salt Lake City's "No Kings" project told through the lens of on-the-scene Salt Lake Tribune photographers.
