(FILES) This image grab taken from a propaganda video released on July 5, 2014 by al-Furqan Media allegedly shows the leader of the Islamic State (IS) jihadist group, Abu Bakr al-Baghdadi, aka Caliph Ibrahim, adressing Muslim worshippers at a mosque in the militant-held northern Iraqi city of Mosul. The Russian army on June 16, 2017 said it hit Islamic State leaders in an airstrike in Syria last month and was seeking to verify whether IS chief Abu Bakr al-Baghdadi had been killed. In a statement, the army said Sukhoi warplanes carried out a 10-minute night-time strike on May 28 at a location near Raqa, where IS leaders had gathered to plan a pullout by militants from the group's stronghold. / AFP PHOTO / AL-FURQAN MEDIA / --/AFP/Getty Images
