An "intentional" explosion linked to a motorhome has rocked the city of Nashville in the US.

It happened at 6.30am in an area of central Nashville packed with bars, restaurants and shops, police said.

The blast sent shattered glass and debris flying through the air as black smoke and flames billowed from the vehicle.

Metro Nashville Police believe the explosion was an "intentional act", although the motive is not yet known.

There have so far been no significant injuries reported but three people have been taken to hospital.
