Turkish President Recep Tayyip Erdogan has announced that the leader of the Islamic State (ISIS) terror group has been killed in a raid in the northern Syrian town of Jandaris, which was carried out by Turkey's MIT intelligence agency. The suspected leader, codenamed Abu Hussein al-Qurashi, was "neutralized" in the operation, and his death is a major blow to the terror group, which has been weakened in recent years. It is hoped that this will be a major step in the eventual defeat of the terror group.
