Merseyside Police has said it believes that a fire has destroyed all vehicles in a multi-storey car park - which has a capacity of 1,600 - 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.
