Islamic State terrorists are teaching their fighters to eat non-Muslims, it has emerged. A handbook found in the terror group's training school has been found by a British counter-extremism think tank, revealing the horrifying new stance of the jihadis. ISIS chiefs even give advice on what parts of the body to eat and how to prepare them and comes after a sickening report a mother was fed the remains of her own son when she was told by the terrorists it was meat and rice.
