Multiple people have been killed in a mass shooting in the US state of Florida, where a gaming event was underway.

One suspect was dead at the scene after the shooting in the downtown area of Jacksonville Landing marketplace, where a video game tournament was underway on Sunday, according to police.

The latest death toll stood at four while 11 were said to have been injured.

Gunshots can be heard in recordings of a Madden NFL video game that was underway in Chicago Pizza at the Landing.

The GLHF Game Bar in the Jacksonville Landing, which was hosting the tournament, has said that all staff members and the owner were able to escape “untouched.”

“SWAT is doing a methodical search inside The Landing,” the Jacksonville Sheriff’s Office said. “We will get to you. Please don’t come running out.”
