Five people were shot — three of them fatally — at an annual carnival outside Salt Lake City, Utah, authorities said. One of those killed was an infant, police said.

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.

At least one person was critically injured Saturday in a shooting at a protest against President Donald Trump in Salt Lake City. It came hours after two Democratic lawmakers in Minnesota were shot dead by a gunman.
