Authorities say five people were killed and eight were wounded after a lone suspect opened fire at the Fort Lauderdale-Hollywood International Airport in Florida. The Broward County Sheriff's Office tweeted the information following Friday afternoon's shooting. Broward County Mayor Barbara Sharief told CNN that authorities "have an active crime scene investigation involving terminal 2." News stations showed video of medics taking care of a bleeding victim outside the airport. Helicopters hovering over the scene showed hundreds of people standing on the tarmac as an ambulance drove by and numerous law enforcement officers, including tactical units, rushed to the scene. Former White House spokesman Ari Fleischer tweeted that he was at the airport when shots were fired and "everyone is running." This is a developing story. Check back for updates.
