West Pier on fire!

Brighton’s poor old West Pier is on fire. Yet more trouble for the beleaguered land mark. See the BBC webcam footage.
It’s now burnt down to the metal super-structure. I don’t know what can have caused the fire, but my guess is arson. The pier is uninhabited (apart from sea birds) and the electricity must have been cut off since the northern section collapsed, so it doesn’t really leave much else.
