FILE - Undated file picture released on Wednesday Jan. 29, 2014, by the official website of Iraq's Interior Ministry claims to show Abu Bakr al-Baghdadi, the head of the so called Islamic State of Iraq and the Levant. While his may not be a household name, Al-Baghdadi has emerged as one of the world's most lethal terrorist leaders. He is a renegade within al-Qaida whose maverick streak eventually led its central command to sever ties, deepening a rivalry between his organization and the global terror network.
