Broward Sheriff Fire Rescue officials told The Miami Herald an aircraft carrying the victims landed at Fort Lauderdale-Hollywood International Airport about 8:30 a.m.
Also reported aboard the plane was former Democratic U.S. presidential candidate John Edwards, who continues to draw headlines for his child-producing extramarital affair. The newspaper said Edwards rode with an ambulance to Broward General Medical Center in Fort Lauderdale with a juvenile victim.
Florida rescue officials said paramedics were standing by when the C-130 military cargo flight arrived from Haiti.
Fifteen of the 33 injured were in serious to critical condition while another 18 were considered "walking wounded," the Herald said.
