Russia’s Defense Ministry says it is investigating reports that ISIS leader Abu Bakr al-Baghdadi was killed in one of its airstrikes in Syria last month.
The leaders were discussing their exit from the city through the so-called southern corridor, the ministry said.
The airstrike was carried out following drone footage confirmation of the council’s meeting location, state-run Sputnik reports.
CNN is not able to verify the Russian claims, and there have been multiple reports of Baghdadi’s death in the past that have turned out to be false.
Al-Baghdadi: An elusive and brutal leader
Officials had long described the ISIS leader as enemy No. 1 in the fight against ISIS, and speculation had swirled over his whereabouts.
Baghdadi has kept a low profile, speaking out in occasional videos and audio messages .
He gave a sermon at a mosque in the Iraqi city of Mosul in 2014, in which he declared himself the leader of his envisaged Islamic caliphate. The sermon was filmed and widely watched around the world.
US forces captured him in Falluja, Iraq, in 2004. At the time, he was considered a low-level al Qaeda member.
He was freed in 2009, and within a year was the leader of Iraq’s al Qaeda affiliate, heading up a renewed campaign of bombings and assassinations. Al Qaeda leaders later severed relations with him, saying he was insubordinate, killing too many civilians.
As the leader of ISIS — the militant group that declared itself the Islamic State as it grabbed swaths of territory in Iraq and Syria — he earned a reputation for brutality.
The extremist group brought a reign of terror and intimidation into areas where they gained control. And the brutality has continued, despite military setbacks. In one reported case, ISIS slaughtered 163 civilians and left their bodies in the street for days, the United Nations said.
US authorities offered a $25 million reward for information leading to his capture .
