Police and firefighters responded to the scene on 2nd Street and Central Avenue at about 10:15 a.m. First responders reported multiple victims, with CPR required for several of them, local US media said.
Parade-goers scattered as gunshots rang out, leaving behind chairs, baby strollers and blankets they had brought to what they innocently believed would be a nice, peaceful outing.
The parade has been completely halted, with police now patrolling the area with rifles. There is no word yet on whether a suspect has been apprehended or identified.
