US:- Police in Florida have questioned a suspected gunman after five people were killed and eight injured in a shooting at Fort Lauderdale airport.
The suspect has been identified by police as 26-year-old Esteban Santiago, an Iraq war veteran.
Officials say they have not ruled out terrorism as a possible motive.
US media say the man may have been mentally disturbed. He reportedly said the government was controlling his mind and made him watch jihadist videos.
The attacker opened fire at the baggage claim area of Terminal 2 as passengers were collecting their luggage. Witnesses said he walked along the carousals and did not say anything as he shot people who were trying to run or hide.
He surrendered to police when he ran out of ammunition, witnesses added.
The man, who was wearing a Star Wars T-shirt, had travelled from Alaska, officials said. He checked in an unloaded gun and ammunition with his luggage, and loaded the semi-automatic gun in the bathroom after landing and collecting his bag.
The suspect is a former member of the Puerto Rico and Alaska National Guard
“We are looking at all avenues. We have not ruled out terrorism and we will be pursuing every angle to try to determine the motive behind this attack,” the FBI’s George Piro told journalists.
Sheriff Scott Israel earlier said it appeared that the suspect had acted alone.
Mr Santiago is expected to face federal charges and make his first appearance in court on Monday.
The suspect is a former member of the Puerto Rico and Alaska National Guard, according to the Pentagon. He served in Iraq from April 2010 to February 2011, and ended his service in August 2016.
US media reported that he had received a general discharge from the Alaska National Guard for unsatisfactory performance.
