Several people have been killed in a mass shooting at an entertainment complex in Jacksonville, Florida, police say.
The sheriff’s office said on Twitter that many people had been wounded and urged people to avoid the area.
They said a suspect was dead at the scene, as searches continued in case anyone else is involved.
The shooting happened during a video game tournament being held in Jacksonville Landing.
Many shots can be heard in a video that appears to show the event being streamed online on the Twitch platform.
The players were playing the American football game Madden at the time.
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”.
“I am literally so lucky. The bullet hit my thumb,” he tweeted.
EA Sports, the company that owns Madden and approved the competition, said it was working with the authorities.
