50 dead in Florida nightclub shooting, worst in US history

Orlando . Fla. (AP) — A gunman wielding an assault-type rifle and a handgun opened fire inside a crowded Florida nightclub early Sunday, killing at least 50 people in the worst mass shooting in American history before dying in a gunfight with SWAT officers, police said.
Authorities were investigating it as an act of terrorism.
At least 53 other people were hospitalized, most in critical condition, officials said.
Mayor Buddy Dyer said all of the dead were killed with the assault rifle.
The suspect exchanged gunfire with an officer working at the gay club known as Pulse around 2 a.m., when more than 300 people were inside. The gunman then went back inside and took hostages, Police Chief John Mina said.
Around 5 a.m., authorities sent in a SWAT team to rescue the hostages. Police have not determined an exact number of casualties, but Mina said “approximately 20” bodies were inside the club.
Authorities were looking into whether the attack was an act of domestic or international terror, and if the shooter acted alone, according to Danny Banks, an agent with the Florida Department of Law Enforcement.
The suspect was identified as Omar Mateen of Port St. Lucie, Florida.
Rep. Alan Grayson named the shooter, citing law enforcement officials. A federal law enforcement official with knowledge of the investigation also confirmed the name. The official was not authorized to discuss the investigation publicly and spoke on condition of anonymity.
Dozens of police vehicles swarmed the area around the club. At least two police pickup trucks were seen taking what appeared to be shooting victims to the Orlando Regional Medical Center.
Pulse posted on its own Facebook page around 2 a.m.: “Everyone get out of pulse and keep running.” Just before 6 a.m., the club posted an update: “As soon as we have any information, we will update everyone. Please keep everyone in your prayers as we work through this tragic event. Thank you for your thoughts and love.”
President Barack Obama was briefed on the attack and has asked for regular updates on the investigation, the White House said.
The attack follows the fatal shooting late Friday of 22-year-old singer Christina Grimmie, who was killed after her concert in Orlando by a 27-year-old Florida man who later killed himself. Grimmie was a YouTube sensation and former contestant on “The Voice.”
