'Multiple fatalities' in Orlando: sheriff

There are "multiple fatalities" in a shooting in a commercial district in Orlando, Florida, the local sheriff has said.

The Orange County Sheriff's Department tweeted that deputies were at a "shooting scene that has stabilised" with the situation "contained."

Orlando was the scene of a massacre on June 12, 2016, when a gunman vowing allegiance to the Islamic State movement killed 49 people in a gay nightclub.

More to come.
