isis-school-textAn ISIS school text book has revealed how the terror group brainwashes its ‘cubs of the caliphate’ by including pictures of deadly weapons.

Mathematics is taught using pictures of deadly weapons and in one question pupils are tested on their addition with pictures of AK-47s and sub-machineguns.
