Abu Bakr al-Baghdadi, the head of the Islamic State (ISIS) militant group, has been careful to reveal little about himself and his whereabouts.
In October 2011, the US officially designated Baghdadi as "terrorist" and offered a $10m (£5.8m; 7.3m euros) reward for information leading to his capture or death.
It notes Baghdadi's aliases, including Abu Duaa and Dr Ibrahim Awwad Ibrahim Ali al-Badri al-Samarrai.
