A participant in a video game tournament in Jacksonville, Florida, has shot dead two people before killing himself, police say.

They named the killer as David Katz, 24, from Baltimore and say he used one hand gun. No other suspects are sought.

Eleven other people were injured on Sunday at Jacksonville Landing, a large shopping and entertainment complex.

Some unconfirmed reports say Katz had become angry after losing at the American football eSports event.

The victims are not being officially named until their next-of-kin are informed, although tributes to two gamers have started appearing on social media.

Florida has seen several mass shootings in recent years, including at the Pulse nightclub in Orlando in 2016, when 49 people died, and the Marjory Stoneman Douglas School in Parkland in February this year, when 17 people were killed.

'Worst day of my life'

A video stream of the event being aired on the Twitch platform appears to show two competitors playing a game when a red dot flashes on one of their sweatshirts, followed by gunfire.

Drini Gjoka, a 19-year-old player taking part, described the shooting in a series of posts on Twitter, calling it "the worst day of [his] life".

He tweeted that a bullet had hit his thumb.

Another competitor Chris "Dubby" McFarland said a bullet had grazed his head.

People fled for shelter when the shooting began and police appealed to them to stay calm as Swat teams checked the area for possible accomplices before it was confirmed that only one gunman had been involved.

Some reports in US media say Katz was a known gamer, using the name "Bread" or "Sliced Bread", and had been the winner of at least one Madden championship in 2017.

He was believed to have been staying in a nearby hotel.

The FBI confirmed its agents had searched the home of Katz's father in the Inner Harbor area of Baltimore on Sunday evening.

'Scared for my life'

Taylor Poindexter from Chicago said she saw the gunman taking aim at people in the room.

"We did see him, two hands on the gun, walking back, just popping rounds," she said. "I was scared for my life and my boyfriend's."

"There were nine victims transported by JFRD [Jackonville Fire and Rescue Department] to area hospitals. Some of those have gunshot wounds. There were two additional gunshot victims that self-transported themselves to local hospitals," said Sheriff Mike Williams.

"Tonight, Jacksonville is mourning. We've faced an occurrence that is all too common that will require us to continue to do the hard work of public safety," said Jacksonville Mayor Lenny Curry.

EA Sports, the company that owns Madden and approved the competition, told the BBC it was "devastated by this horrific event... a senseless act of violence that we strongly condemn".

It sent its heartfelt sympathies to the families of the victims.</s>Police investigate the scene of a multiple shooting at the Jacksonville Landing after a mass shooting during a Madden Championship Series competition at the Good Luck Have Fun video game bar inside Chicago Pizza at The Jacksonville Landing.

JACKSONVILLE, Fla. — A gunman opened fire Sunday at an online video game tournament as it was being livestreamed from a Florida mall, killing two people and then fatally shooting himself in an attack that sent several others to hospitals, authorities said.

Jacksonville Sheriff Mike Williams said authorities believe 24-year-old David Katz of Baltimore carried out the attack using at least one handgun at the Jacksonville Landing, a collection of restaurants and shops along the St. Johns River. He said the man died from a self-inflicted gunshot, adding authorities were still making final confirmation of his identity with the FBI assisting them in Baltimore.

Nine other people were wounded by gunfire and all were in stable condition Sunday evening after going to hospitals, Williams said. He added that two others were hurt as people sought to flee the gunfire in the panic and chaos that ensued.

Katz was in Jacksonville for the “Madden NFL 19” video game tournament, authorities said. The games maker, EA Sports, lists a David Katz as a 2017 championship winner.

Thee competition was held in a gaming bar that shares space with a pizzeria. Viewers could watch the games online and see the players.

Investigators were looking into online video that appeared to capture the scene right before the shooting began, Williams said. A red dot that appears to be a laser pointer is visible on the chest of a player seconds before the first of about a dozen gunshots rings out.

Marquis Williams, 28, and his girlfriend, Taylor Poindexter, 26, both from Chicago, were ordering pizza at the bar when they heard the first shot.

“Initially we thought it was a balloon popping, but there weren’t any balloons in the room,” said Williams, who had taken part in the tournament earlier. “Then we heard repeat shots and we took off running.” Williams added: “The first shot everybody just turned and looked. After the second, third and fourth shots, everybody took off and ran for the exits.”

Taylor Poindexter, an aspiring gamer, said she had hoped to gain some experience at the tournament. She said she never saw the face of the man who was shooting. But she recalled, “We did see him with two hands on a gun walking back just popping rounds.”

He said the two ran to a nearby restaurant where workers were waving people in, hiding in a bathroom until police arrived.

Jason Lake, the founder and CEO of compLexity, a company that owns professional e-sports teams, said on Twitter that one of his players, 19-year-old Drini Gjoka, was shot in the thumb.

Gjoka tweeted: “The tourney just got shot up. Im leavinng and never coming back.” Then: “I am literally so lucky. The bullet hit my thumb. Worst day of my life.”

On Sunday evening, an FBI official in Baltimore confirmed that its agents were searching the family home of the man authorities said they believe was behind the attack. An FBI spokesman, Dave Fitz, said agents had gone to the house of the man’s father in Baltimore. He declined to release specifics, citing the ongoing investigation.

In Washington, White House spokeswoman Sarah Huckabee Sanders said President Donald Trump had been briefed on the attack and the White House was monitoring the situation.

The Jacksonville Landing, in the heart of the city’s downtown, also hosts concerts and other entertainment. It was the site of a Trump rally in 2015, early in his campaign for the White House.

The sheriff’s office used Twitter and Facebook immediately after the shooting to warn people to stay far away and to ask anyone who was hiding to call 911. Police also barricaded a three-block radius around the mall and police boats patrolled the nearby river. Police also took up positions on a bridge overlooking the river.</s>Jacksonville Sheriff's Office says there's been a mass shooting at the Jacksonville Landing; people told to stay away
