BEIRUT — The Islamic State group's spokesman and chief strategist, who laid out the blueprint for the extremist group's attacks against the West, has been killed while overseeing operations in northern Syria, the group has announced.
The IS-run Aamaq news agency said Abu Mohammed al-Adnani was "martyred while surveying the operations to repel the military campaigns in Aleppo." It did not provide any further details on when or how he died. A later statement issued by the Islamic State group in Aleppo province vowed to avenge his death. Both statements were released late Tuesday evening.
Russia's Defense Ministry said on Wednesday that its airstrike killed al-Adnani. In a statement, the Defense Ministry said its intelligence had confirmed that a Russian airstrike on Aleppo province had killed 40 IS militants, including the group's spokesman.
On Tuesday, Pentagon Press Secretary Peter Cook said that a U.S. airstrike targeted al-Adnani in the Syrian city of al-Bab, which is northeast of Aleppo. He said the U.S. was "still assessing the results of the strike."
His death is a major blow to the extremist group, which has been on the retreat in Syria and Iraq.
Al-Adnani, whose real name is Taha Sobhi Falaha, persistently called for attacks against the West, which paid off in bloody notoriety with the Nov. 13 coordinated attacks in Paris that hit a concert hall, a stadium and restaurants and bars, leaving 130 people dead and hundreds wounded.
He was a Syrian who was born in the northern province of Idlib and is believed to have been in his late 30s. He crossed the border and joined al-Qaida in Iraq, a precursor to IS, after the 2003 U.S.-led invasion.
In late June 2014, he formally declared the establishment of a caliphate, or Islamic state, stretching across parts of Syria and Iraq, under the leadership of Abu Bakr al-Baghdadi, and demanded allegiance from Muslims worldwide.
