'Mass Casualty Situation' after Florida nightclub shooting
ORLANDO, Fla. (AP) - Police say the person who opened fire inside a popular Florida nightclub is dead.
Orlando Police did not immediately provide further details on the department's official Twitter account on Sunday.
A gunman opened fire at a nightclub in central Florida, and multiple people have been wounded, police said Sunday.
"Multiple injuries" were reported following the shooting at Pulse Orlando nightclub, which describes itself on Facebook and its website as a gay bar.
Orlando Police told people on the department's official Twitter account to stay away from the area.
Multiple emergency vehicles have reportedly responded, including the Orlando Fire Department's bomb squad and hazardous material team.
Police said via Twitter that a noise heard near the shooting site was a "controlled explosion," and asked media to avoid "reporting inaccuracies." No other details were provided.
Pulse Orlando's earlier posted on its own Facebook page: "Everyone get out of pulse and keep running."
Police described the shooting as a "mass casualty situation" and said local, state and federal agencies were involved in the investigation.
It was not immediately clear how the shooter died.
The incident follows the fatal shooting on 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."
