WASHINGTON -- A captured member of the Islamic State of Iraq and the Levant claims that the ISIL and other Islamic militant groups in Syria not only are supported by a member of the Saudi royal family but that individual actually heads the ISIL.In a video admission, a captured member of the ISIL said the radical Islamic group actually is led by Prince Adbul Rahman al-Faisal, the son of the late King Faisal of Saudi Arabia and the brother of the current Saudi Foreign Minister, Prince Saud al-Faisal.

Notice how ISIL was careful to state its independence from Al-Qadea. I speculated that ISIL's attack in Iraq might have the aim of opening a second front against Iran (and BTW Syria). Looks like I might be right.
