Police say an officer working as a security guard inside the Pulse nightclub exchanged fire with the suspect at about 2am local time (7am UK time), before a hostage situation developed, a team of officers entered the club and shot dead the gunman.
Police identified the attacker as Omar Mateen, a 29-year-old from Port St. Lucie, Florida – more than 100 miles away from Pulse.
His family is from Afghanistan, while Mateen is believed to have been born in the United States.
Mr Mateen, who is said by the FBI to have "leanings" towards extremism and Isis, was involved with a stand-off with officers for around three hours before SWAT teams stormed the building and shot him dead.
