A senior researcher at the Russian Academy of Sciences Institute of Oriental Studies, Boris Dolgov, claims the Islamic State no longer exists and has been taken down in Iraq and Syria. This could be based off the recent blows to the IS, such as the recent killing of Aku Bakr al-Baghdadi. However, even in some of these defeats the Islamic State has done extreme damage; when being driven out of their territory in Syria the group pulled off numerous attacks, killing around 215 people. IS prisoners have also been escaping prison ground in Turkey and Syria. While the terrorist faction no longer holds territory, they have returned to their roots and moved underground where they previously were able to coordinate devastating attacks.
