Nobody should believe the new western nonsense that the Saudi backed „Islamic Front“ is different to and an opponent of the syrian Al Qaeda affiliates ISIS and Jabhat al Nusra. The foreign Jihadis flocking to Syria to wage a sectarian „Jihad“ are not merely contained to these two organizations:

„Throughout the Syrian civil war, one of the major concerns of Western powers in particular has been the inflow of Sunni foreign fighters, who come from the wider Arab world, Western Europe, and as far afield as Kazakhstan and Indonesia…According to a recent estimate by Aaron Zelin of the Washington Institute for Near East Policy, there could be up to 11,000 of these fighters…there are the two groups Suqour al-Izz and Harakat Sham al-Islam. The former, founded at the beginning of this year, is led by Saudi foreign fighters; the latter, established in the summer, is led by Moroccan foreign fighters…The Green Battalion is based in the Qalamoun area of Damascus province and was founded in the summer by Saudi fighters …Jamaat Jund ash-Sham was founded last year by Lebanese fighters in western Homs governorate…“
