A gunman opened fire Friday at Fort Lauderdale-Hollywood airport, a major tourist hub in Florida, killing five people and injuring eight.
The suspect, who was in possession of a military ID, was in custody and being questioned by the FBI over the shooting that shut down the international airport and gateway to the Caribbean.
The incident occurred in the baggage claim area of Terminal 2, as passengers collecting their luggage were interrupted by the alleged gunman, whose papers identify him as 26-year-old Esteban Santiago.
There was no immediate indication of a motive for the assault, in a country where gun violence is widespread due to the ready availability of firearms.
ABC News said that the gunman had traveled from Alaska to Fort Lauderdale, with a stopover in Minnesota. According to CBS he engaged in an argument on one leg of the trip.
The suspect checked a gun inside his luggage, after declaring the weapon with airport authorities, then used it to take down his victims, CNN reported, citing law enforcement sources.
He was then detained without law enforcement firing any shots.
