A shooter killed four people and wounded 10 others today at a video game tournament that was being streamed online from a restaurant in Jacksonville, Florida, local media said citing police sources.
The Jacksonville Sheriff's Office said a suspect was dead at the scene. "Searches are being conducted," it said on Twitter.
Emergency crews and law enforcement flooded into The Jacksonville Landing, a waterfront dining, entertainment and shopping site in the city's downtown.
The shooting took place during a regional qualifier for the Madden 19 online game tournament at the GLHF Game Bar inside a Chicago Pizza restaurant, according to the venue's website.
It was live-streaming the tournament when several shots rang out, according to video of the stream shared on social media. In the video, players can be seen reacting to the gunfire and cries can be heard before the footage cuts off.
The Los Angeles Times reported the shooter was a gamer who was competing in the tournament and lost. Citing messages from another player in the room, the Times said the gunman appeared to target several victims before killing himself. Reuters could not immediately confirm that account of events.
The Florida shooting occurs amid a debate about US gun laws that was given fresh impetus by the massacre in February of 17 people at a high school in Parkland, Florida.
Two years ago a gunman killed 49 people at the Pulse nightclub in Orlando.
The sheriff's office said many people were transported to hospital, and its deputies were finding many people hiding in locked areas at The Landing.
"We ask you to stay calm, stay where you are hiding. SWAT is doing a methodical search," it said on Twitter. "We will get to you. Please don't come running out."
A spokesman for Jacksonville's Memorial Hospital, Peter Moberg, said it was treating three victims, all of whom were in stable condition.
Florida Governor Rick Scott said he had offered to provide local authorities with any state resources they might need.
Have confirmed @FBI & @ATFHQ are in contact & in coordination with local authorities to provide any & all federal resources needed to respond to #JacksonvilleLandingShooting.
