BEIRUT (Reuters) - Islamic State (IS) insurgents in Iraq and Syria have issued a pamphlet calling for Muslims to pledge loyalty to their chief, Abu Bakr al-Baghdadi, pressing a campaign to establish a "caliphate" even as U.S.-led forces bomb their positions.
Baghdadi's claim to the mantle of Islam’s caliphate, the Muslim state established by the Prophet Mohammad’s first followers after his death, has infuriated many Islamic leaders and ignited an ideological battle for legitimacy.
