Police in the US state of Florida say there have been "multiple fatalities" in a shooting in Orlando.

The shooting happened early on Monday morning in the east of the city, the Orlando Sentinel newspaper reports.

It comes a week before the first anniversary of the Pulse nightclub shooting in the city - the deadliest mass shooting in US history - in which 49 people died.

The Orange County sheriff is expected to give a briefing soon.

Police said the scene of the shooting had been "stabilised", indicating the shooting was not ongoing.
