There are multiple injuries after an attacker opened fire inside a gay nightclub in the Florida city of Orlando, police say.
The attacker is reported to be still inside the Pulse Club and to have taken hostages.
A bomb squad and hazardous material team are at the scene, the Associated Press reports. Orlando Police have urged people to stay away.
Some reports say at least 20 shots were heard inside the club.
Video footage being shared on social media showed dozens of emergency vehicles at the scene and people being treated on the pavements.
More than 100 people were reported to have been enjoying a Latin-themed night in the club, which is situated near Orange and Kaley avenue.
Local TV reporter Stewart Moore earlier tweeted that he had been told by a source that more than 20 people had been shot.
He said the attacker was still inside the nightclub with hostages, and was feared to be wearing a bomb.
The incident comes as Orlando is still reeling from the fatal shooting on Friday night of 22-year-old singer Christina Grimmie following a concert in the city.
She had been signing autographs when she was shot by 26-year-old Kevin James Loibl, who then killed himself. It is not clear what Loibl’s motive was.
