In October 2011 the US officially designated Baghdadi, 44, as a terrorist, and offered a £6m reward for information leading to his capture.
Rumours that he had died surfaced last year after reports that he had been seriously wounded in an air strike.
But he is believed to be in Syria still wielding power over the terror group.
