At least 50 people have been killed and 53 injured after a gunman launched what police say was a "domestic terrorism incident" at a gay nightclub in Orlando, Florida.
Here are the latest updates:
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.
