At least 19 people are injured after a stampede breaks out during an annual motorcycle rally in Atlantic Beach, South Carolina, according to local and regional reports. NBC News and other outlets cite Horry County Fire Rescue as saying the injured are not believed to have life-threatening injuries. Authorities have not released a definitive cause publicly, but the town of Atlantic Beach says the incident is triggered by a person who starts running, leading to a brief chain reaction within the crowd that lasts only seconds.
Reports describe the event as taking place Sunday morning at the beach area during the biker-related festival or rally. While all sources converge on the number of injured and the location and timing, they do not provide consistent additional details beyond the initial trigger described by the town. A probe is underway to determine what led to the sudden movement of the crowd and to clarify the circumstances surrounding the stampede.
