DHAKA: At least 20 people have been killed and some 42 injured in a shooting at a gay nightclub in Orlando, Florida, police say.
Orlando Police said officers entered the Pulse Club about three hours after the shooting unfolded - and killed the gunman, who had taken hostages.
The BBC understands the name of the suspect was Omar Mateen, aged 29.
Police called the shooting an act of terrorism, but said they did not know if it was domestic or international.
It is believed that the suspect was not on a terrorism watch list, although he was currently being investigated for an unrelated criminal act.
Relatives have been gathering at local hospitals desperate for news of their loved ones.
Many had received calls and texts from loved ones inside the club as the siege began, and some have heard nothing since.
President Barack Obama was briefed about the shooting and asked to receive regular updates, a White House statement said.
Orlando Police Chief John Mina said the attack began at 02:00 (06:00 GMT). There was an exchange of fire with a police officer working at the club, but it is unclear whether that was inside or outside the venue.
After this a ‘hostage situation’ unfolded, he said.
