Russia's defence ministry is investigating whether one of its air strikes in Syria killed the leader of the Islamic State militant group (IS).The ministry said an air strike may have killed Abu Bakr al-Baghdadi on 28 May.
The raid targeted a meeting of the IS military council in its de-facto capital of Raqqa in northern Syria.There have been a number of previous reports of Baghdadi's death.His whereabouts have been unknown for some time, although he was believed to be in Mosul in Iraq before a US-led coalition began an effort to reclaim the city in late 2016.
