Something has gone badly wrong in Paris. Hordes of the undead roam the streets, shuffling towards you, covered in blood and gore, some fresh from their weddings, others from their funerals. That's the scenario imagined by the 6th Paris Zombie Walk, which happens every October in the run-up to Hallowe'en. So if you dare, check out these 10 images of this year's zombie invasion. Some of them are frighteningly realistic, and may not be appropriate for children.
