Police say several people have lost their lives in a mass shooting at an entertainment complex in Jacksonville, Florida.
The sheriff’s office took to Twitter to report 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.
A 19-year-old player taking part, Drini Gjoka, 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.
The local sheriff’s office said on Twitter that Swat teams were continuing to search the area.
They said that they had found “many people” still hiding there and urged them to stay calm.
Local media report that at least four people have been killed, and at least 11 others are injured.
