In Orlando, Florida,
at least 20 people 49 people are dead and 53 were taken to the hospital after a gunman began to open fire at a gay nightclub (Pulse) around 2 a.m. this morning. Orlando Police Chief John Mina said that an officer did engage the gunman outside of the club, which devolved into a hostage situation. A special weapons and tactics team was deployed, and around 5 a.m. Chief Mina said a decision was made to rescue the hostages, around 30, who were still inside the club. The bomb squad was called in to denote two controlled explosions as a diversion. The gunman was shot and killed in that effort. The gunman was armed with a rifle, a handgun, and had some type of device on him. The FBI is now involved in what police are calling an “act of domestic terror” (via CNN):
Approximately 20 people are dead inside Pulse nightclub, Orlando Police Chief John Mina said Sunday morning, just hours after a shooter opened fire in the club. At least 42 people have been transported for medical treatment, he said.
Police have shot and killed the gunman, Mina told reporters.
"It's appears he was organized and well-prepared," the chief said, adding that he had an assault-type weapon and a handgun.
Orlando authorities said they consider the violence an act of domestic terror. The FBI is involved.
The shooting began around 2 a.m., and an officer responded, Mina said. The officer engaged in a shoot out outside the club. The gunman then ran into the club.
"That turned into a hostage situation," Mina said. Authorities were getting calls from people inside the club but away from the gunman, the chief said.
More police rushed to the scene and broke down a door with an armored vehicle. At that point police shot and killed the gunman, Mina said.
USA Today reports that contrary to initial reports, there appears to be only one gunman.They also reiterated that this is considered a “domestic terror incident,” and “authorities are investigating whether the incident was the work of Islamic terrorism.” Concerning whether the gunman was inspired by Islamic terrorism, the FBI said, "we do have suggestions that that individual may have leanings toward that, that particular ideology. But right now we can't say definitively so we're still running everything around."
