Mass shooting occurred at Pulse gay nightclub in Orlando. The city Mayor Buddy Dyer confirmed that at least 50 people were killed and 53 more were injured in the shooting.
US national Omar Saddiqui Mateen had come in sight of the US Federal Bureau of Investigation (FBI) for the first time in 2013, Ronald Hopper, the FBI assistant agent in charge, said.
"The FBI first became aware of Mateen in 2013 when he made inflammatory comments to co-workers alleging possible terrorist ties," Hopper told reporters.
According to Hopper, the FBI then questioned Mateen twice, but failed to confirm the man's ties with terrorists and the investigation was closed.
The attack was conducted by US national Omar Saddiqui Mateen.
"At the moment we do not have a second suspect to look for. We do not know of any confirmed threats in the Orlando area or in the country. "
