A train operator was killed in Disney World's Magic Kingdom after two monorails collided.

The deputy chief of a local fire department, Bo Jones, said the train operator died at the scene of the crash.

The other train operator was not injured, but was taken to hospital because he was shaken up. Five park guests were treated at the scene.

Jones said it was unclear what caused the crash which happened at the park's ticket and transportation centre.

Walt Disney World vice president of public affairs Mike Griffin issued a statement offering condolences to the employee's family and saying the monorail was closed.
