Members of the Iraqi Special Operations Forces (ISOF) prepare before going out on a patrol in the town of Jurf al-Sakhar, south of Baghdad,June 30, 2014. Iraqi troops battled to dislodge an al Qaeda splinter group from the city of Tikrit on Monday after its leader was declared caliph of a new Islamic state in lands seized this month across a swathe of Iraq and Syria. Alarming regional and world powers, the Islamic State of Iraq and the Levant (ISIL) claimed universal authority when it dropped the local element in its name and said its leader Abu Bakr al-Baghdadi, as leader of the Islamic State, was now caliph of the Muslim world - a medieval title last widely recognised in the Ottoman sultan deposed 90 years ago after World War One.
