MOSCOW (Reuters) - The likelihood that Islamic State in Iraq and Syria (ISIS) leader Abu Bakr al-Baghdadi has been killed is close to 100 per cent, Interfax news agency quoted Viktor Ozerov, the head of the defence committee in the Russian upper house of parliament, as saying on Friday.

"I think this information is close to 100 per cent," the agency quoted Ozerov as saying.

"The fact that Islamic State has still not shown him anywhere also adds to our confidence that al-Baghdadi has been killed."
