WASHINGTON, Aug. 26 (CGTN) -- At least two people were killed and 11 others wounded on Sunday when a video gamer opened fire at a tournament that was being streamed online from a restaurant in Jacksonville, Florida police said.

Jacksonville Sheriff Mike Williams named the shooter as David Katz, 24, of Baltimore and said he was in town for the competition, adding that Katz killed himself after the shooting and that his body was found along with those of his two victims.

The sheriff's office said 11 people were wounded by the gunfire, and at least two others were injured while fleeing the scene.

"Multiple fatalities at the scene, many transported," the Jacksonville Sheriff's Office said on twitter, following up on earlier reports of the shooting in 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.

The bar was livestreaming the football video game competition when the gunfire started, according to video of the stream shared on social media.

Top figures from the professional US online gaming community expressed shock and dismay on Sunday after the shooting.

The killings also rocked the world of professional electronic gaming, also known as eSports, which boasts an estimated 250 million players worldwide in a growing market worth about a billion dollars a year.

This is the third major mass shooting to hit Florida in the last two years.
