Scores of people watching a Fourth of July fireworks show in Philadelphia ran for cover when gunshots rang out, forcing them to leave behind strollers and other personal items as they sought refuge from what many feared was an active shooter.
Two Philadelphia police officers working at the event suffered graze wounds when shots were fired shortly after the event started Monday in front of the Philadelphia Art Museum. The gunfire came just hours after another holiday shooting in suburban Chicago left at least six people dead and at least 30 wounded.
