Back in June last year the Russian Ministry of Defence published a claim that a meeting of ISIS commanders in May, in the then besieged ISIS 'capital' of Raqqa, included no less a person than ISIS's leader - Ibrahim Abu-Bakr Al-Baghdadi - himself. The meeting was apparently called to plan the escape of ISIS's top leaders from Raqqa. Of these the most important obviously is Al-Baghdadi himself, which was presumably why he attended the meeting.
Russian intelligence apparently got wind of the meeting, and the building in Raqqa where it took place was destroyed in an air strike carried out by a Russian SU-34 fighter bomber belonging to the Russian Aerospace Forces.
The Russians subsequently claimed that Al-Baghdadi himself was killed in the air strike along with a number of other top ISIS officials.
The claim received corroboration from the Syrian Observatory for Human Rights, but it was refuted by US and Iraqi officials, and I myself expressed skepticism about it on the grounds that Al-Baghdadi's pivotal role in ISIS as its erstwhile "Caliph" meant his death would be expected to have a more visible effect on the organisation than appeared to be the case.
Comment: The Syrian Observatory for Human Rights is not a reliable source of information. It consists of a 'home' office in Coventry, England, run by one guy, Rami Abdulrahman, and is only one of many such disinformation churners funded by Soros. Its mission is to slant or falsify the news to the detriment of Syria and Russia in order to sway the opinions and beliefs of Western policy makers and the public -- a neocon tool for 'opposition propaganda'.
