Police in the US say that the number of people believed to have been killed in the mass shooting at Florida’s gay nightclub has gone up to 50.
Dozens are reported to be injured and taken to local hospitals.
The gunman , identified as Omar Mateen, was killed after taking hostages.
It is the worst mass shooting in recent US history.
Officials said the killings were likely to be ideologically motivated, though there was no information that the gunman was associated with a particular group.
Quoting Orlando Police, BBC reported that officers entered the Pulse Club about three hours after the shooting unfolded and killed the gunman, who had taken hostages.
Calling it an act of terrorism, police said that they did not yet know if it was domestic or international.
Many had received calls and texts from loved ones inside the club as the siege began, and some have heard nothing since.
Orlando Police chief John Chief Mina said a decision was taken at 05:00 to send a police assault team into the club after receiving texts and phone calls from some of the hostages.
“Our SWAT officers exchanged gunfire with the suspect, the suspect is dead,” he said.
“He appeared to be carrying an assault-type rifle and a handgun, and had some type of device on him.”
