Islamic State (ISIS) has published a new edition of the propaganda booklet Dabiq, which is again signaling its primary enemy - Christianity. 

On the cover page of the booklet is a photo of the Vatican bearing the ISIS flag, along with the terror group's desires to conquer Rome and "break the cross." 

According to some Islamic traditions, the founder of Islam Mohammed predicted that the occupation of the three cities of Istanbul, Jerusalem and Rome pave the way for the appearance of the Mahdi, the Islamic Messiah.
