(DAILY MAIL) -- ISIS has been forced to reorganise and change strategy to survive after a string of devastating defeats four years after announcing its cross-border 'caliphate' in Iraq and Syria.
The jihadist group has been pinned down to its last desert holdouts in Syria having lost all urban centres previously under its control in neighbouring Iraq.
It has now changed its administrative structure and shifted its focus away from operating the state-like apparatus it once ran.
