DAMASCUS, Aug. 30 (Xinhua) -- The spokesman of the Islamic State (IS) group, Abu Muhammad al-Adnani, was killed Tuesday during battles in the country's northern province of Aleppo.

The IS' Amaq Agency said al-Adnani was killed "while surveying the operations to repel the military campaigns against Aleppo."

The IS statement didn't specify where exactly he was killed in Aleppo.

He was also one of the main commanders of Abu Bakr Al-Baghdadi, the IS leader.

Born in the countryside of the northwestern province of Idlib, al-Adnani also served in al-Qaida in Iraq in 2003.
