WASHINGTON (Reuters) - The Pentagon confirmed on Monday that Islamic State leader Abu Muhammad al-Adnani was killed in a U.S. air strike on Aug. 30 in Syria.

The United States had said on Aug. 30 that Adnani had been targeted in a strike, but it stopped short of confirming his death. Russia's Defense Ministry said on Aug. 31 that a Russian air strike had killed Adnani.
