Law enforcement from multiple agencies, including the FBI, are investigating a shooting at an Orlando nightclub.
Police said a shooter armed with an assault rifle and a handgun entered the Pulse Orlando, a gay nightclub, around 2 a.m. Sunday, opening fire and killing 49 people and injuring around 53 people. Initial reports said 50 were killed, but police clarified that they did not consider the suspect a victim, so it was adjusted.
News sources later identified the shooter as Omar Mateen, 29.
Mateen was a U.S.-born Florida resident. The FBI became aware of Mateen in 2013 when he made inflammatory comments to coworkers that alleged terrorist activity.
He was interviewed twice, but agents said they were not able to substantiate comments. They said he later had ties to a suicide bomber in 2014.
Agents said the investigations did not provide evidence of close terror ties.
The FBI director said Monday he is highly confident the shooter was radicalized in some part through the internet, claiming ties to Al Qaeda and Hezbollah, a terrorist group FBI describes as a bitter enemy of the Islamic State group.
This is despite the fact officials said Mateen called 911 and expressed support for the Islamic State group immediately before the shooting.
One officer was among those injured, but police officials said the injuries did not appear to be serious. They said the officer was hit in his Kevlar helmet, minimizing injury.
Law enforcement officials said the suspect took hostages, and a situation lasted for hours.
They said at least 30 hostages were saved during a rescue.
Law enforcement said the suspect used an AR-15 and a handgun. Officials said he bought those weapons legally days before the attack.
The shooter died during an exchange of gunfire with law enforcement.
Law enforcement said there was likely only one shooter, though they do believe the individual planned the attacks.
They said they used a "controlled explosion" in the area to distract the shooter.
Police said there is no indication that the incident was related to the Christina Grimmie shooting Friday night.
Law enforcement called the attack an act of terrorism, and the Islamic State group later took credit for the attack.
FBI officials said they are confident there is no other threat related to the incident.
The Imam of Central Florida Islamic Society condemned the attack, standing with law enforcement and city leadership in a press conference Sunday.
IS radio later called him an American soldier of the caliphate.
Both the city of Orlando and the Florida governor declared a state of emergency there.
Hospital officials asked for blood donors to seek out the local blood bank and to donate if possible.
City officials said they are working to identify victims and notify family members.

Our thoughts and prayers are with the families and loved ones of the victims. The President asked to receive regular updates as the FBI, and other federal officials, work with the Orlando Police to gather more information, and directed that the federal government provide any assistance necessary to pursue the investigation and support the community."

"My prayers are with the victims’ families & all those affected by the shooting in Orlando. We will devote every resource available to assist."
