In a twisted new set of online guidelines, Islamic State leaders are urging its followers in the West to pretend to be Christians before committing lone wolf terrorist attacks. A 58-page terror pamphlet entitled ‘Safety and Security Guidelines for Lone Wolf Mujahedeen’ instructs its adherents to trim their beards, wear Western-style aftershave and even pretend to be Christians by wearing cross necklaces in order to avoid arousing suspicion and ensure success in their operations. It reveals some of the ‘best places’ to carry out terror attacks - such as loud nightclubs - and the guide provides disturbing tips for future jihadists. Over the past year IS has released dozens of online documents, instructing their followers on everything from how to build a bomb factory to how to cross into Syria via Turkey without being caught.
