Yesterday, a statement from Peter Cook, the Pentagon’s Press Secretary, confirmed that the US airstrike on August 30th targeting Abu Muhammad Al-Adnani, one of the Islamic State’s senior leaders was successful. Al- Adnani was responsible not only for a large part of Islamic State’s propaganda but he also recruited and facilitated most of their foreign terrorist operations.

The Department of Defense has confirmed that the U.S. precision airstrike on Aug. 30 targeting senior ISIL leader Abu Muhammad Al-Adnani was successful. The strike near Al Bab, Syria, removes from the battlefield ISIL’s chief propagandist, recruiter and architect of external terrorist operations. It is one in a series of successful strikes against ISIL leaders, including those responsible for finances and military planning, that make it harder for the group to operate. As we continue to gather momentum in our counter-ISIL campaign, we will continue to target ISIL leaders, relentlessly pursue its external plotters, and, working with our partners on the ground, we will not rest in our efforts to destroy ISIL’s parent tumor in Iraq and Syria, combat its metastases around the world, and protect our homeland.- Pentagon Press Release

Shortly after the news broke on the possible death of al-Adnani on August 30th, Russia claimed that he was one of the 40 ISIS fighters killed in their airstrikes.

Abu Mohammed al-Adnani was one of up to 40 rebels who died Tuesday in attacks carried out by a Su-34 bomber in Maaratat-Umm Khaush, Syria, according to Russia’s Defense Ministry. It cited “several intelligence channels.”

A U.S. defense official dismissed that assertion. “We have no reason to believe Russia’s claim,” the official told NBC News. Earlier, a U.S. defense official told Reuters, “Russia’s claim is a joke.”- NBC News

Yesterday’s press release from the Pentagon did not address Russia’s claim specifically but confirmed the his death was the result of a U.S. airstrike.
