The "Fatah al-Islam" really is the Lebanese al-Qaeda. Fundamentalist movement (one of the many Sunni radical groups) that was perhaps funded by Saudi/Lebanese elements in an attempt to re-shape the sectarian scape and re-invigorate and mobilize armed footmen in the secrtarian "struggle". This is a product of Lebanese inner-conflict. I cannot help but think that, due to the group's firepower, that it is/has been backed by governmental forces, because, there is no way that Palestinian factions would supply such a group and risk to the possibility of throwing off the power balance within the camp...impossible. Also, as we have learned from recent reports (and which should have been known all along), the majority of the members are not even Palestinian. Rather, they are Lebanese (mostly), Saudi, Yemeni, Tunisian, etc. I believe that since the refugee camps have been so isolated from everything, that fundamentalist indocrination and arming of such elements by Saudi and Lebanese (and all else who conspire) has not penetrated the camps, rather, it is possible that foreign elements arrive and burrow in the camps in order to dodge certain authority/intelligence apparatuses. Nonetheless, Fatah al-Islam is by no means a legitimate Palestinian nationalist movement. I mean, they have not mentioned one word about Palestine. Doesn't anyone find this strange? And do you really think that secular or leftist elements within the camps would allow them to freely operate and arm had they not power-backing? Highly doubtful. It truly is a by-product of Lebanese sectarianism, which never abstained from dabbling into fundamentalist ideology (particularly against Hezbollah).
