A fire has destroyed all cars in a 1,600 capacity multi-storey car park next to the Echo Arena in Liverpool.

The Liverpool International Horse Show was cancelled as firefighters tackled the huge blaze next to the venue on Liverpool's waterfront.

Merseyside Police said: "Initial investigations indicate that an accidental fire within a vehicle caused other cars to ignite.

"We believe that all vehicles parked in the car park have been destroyed and advise owners to contact their insurance companies."

No-one has been seriously injured, the force said.
