FILE - This undated file image posted on a militant website on Tuesday, Jan. 14, 2014 shows fighters from the al-Qaida-linked Islamic State of Iraq and the Levant (ISIL) marching in Raqqa, Syria. Saudi Arabia and other Gulf petro-powerhouses encouraged a flow of cash to Sunni rebels in Syria for years. But now they face a worrying blowback as an al-Qaida breakaway group that benefited from some of the funding storms across a wide swath of Iraq. Gulf nations fear its extremism could be a threat to them as well. But the tangle of rivalries in the region is complex: Saudi Arabia and its allies firmly oppose any U.S. military action to stop the Islamic State’s advance in Iraq because they don’t want to boost its Shiite-led prime minister or his ally, Iran.
