Da’esh said on Tuesday, August 30th that one of its most prominent and longest-serving leaders was killed in what appeared to be an American air strike in Syria, depriving the militant group of the man in charge of directing attacks overseas. A U.S. defense official told Reuters the United States targeted Abu Muhammad al-Adnani in a Tuesday strike on a vehicle traveling in the Syrian town of al-Bab. The official stopped short of confirming Adnani’s death, however.
