There is a lot of lies and disinformation being spread by Gulf intelligence services about ISIS and their deeds (and they are being readily recyled by Western and Eastern media). I saw this being promoted by director of HRW yesterday. I maintain that the article, which contains lies and exaggerations, are actually helping the propaganda of ISIS. The ISIS are terrorist enough and we don't need to lie and exaggerate to show that they are bad. But there is no evidence that they cancelled classes in history or geography for example. Those are made up. In fact, ISIS closely monitors the inaccurate coverage and then rebuts them carefully on twitter and then makes the point that all coverage of its crimes and excesses are lies.
