The Islamic State (IS) terror group's chief spokesman Abu Muhammad al-Adnani has been killed in the Syrian province of Aleppo, IS-affiliated media group has said.
He was the most prominent leaders of the IS, BBC quoted Amaq News Agency as saying.
Pentagon had targeted Adnani in a precision strike near the town of al-Bab and was still assessing the results.
"We are still assessing the results, but Adnani's removal from the battlefield would mark another significant blow to the IS," the Pentagon said.
Fighting has intensified in Aleppo in recent days, with rebels breaking a blockade by government forces and Syrian and Russian warplanes carrying out air strikes on rebel-held parts.
