The new chief spokesman for the Islamic State group (also called ISIS) promised attacks on the United States, Russia, Europe and Iran in his first address to the terrorist outfit's followers, which was released Monday by ISIS's al-Furqan media division. The audio recording named Abu Hassan al-Muhajir as the successor to Abu Muhammad al-Adnani, who was killed in a U.S. drone strike near al-Bab, Syria, on Aug. 30. In a chilling message -- titled "For You Will Remember What I Tell You" -- aimed at the West and ISIS's regional adversaries, Muhajir called on the group's fighters to target its enemies. According to a translation by Rita Katz, director of the SITE Intelligence Group, Muhajir said in the message: "We will attack them in their own countries. Your operations make a difference … change the situation. Attack them in their markets, roads, clubs and any unexpected location and burn the ground under their feet."
