Probably wise to combine this with the Syrian Civil War topic. It's not particularly surprising, given the increased militarisation of the conflict, the frequent violations by both sides of Annan's peace plan and the increased interference from foreign powers, particularly Iran. It's fast becoming a proxy war between the various Arab League nations and Iran, as to who can bet the most arms on the winning team. Unfortunately, both sides seem to be making use of this foreign "investment" not in the context of legitimate conflict with each other, but in a war of attrition with non-combatants, if not outright civilians the primary targets. Over the last week, I've heard of Assad-loyalist militiamen firing on Jordanian troops, another cross-border shelling at a refugee camp in Turkey, and even rumours that Iran has deployed several hundred armed Imperial Guard as "training and liaison" forces for Assad's armed forces and militias. People have been concerned about other nations being drawn into this conflict- now I'd say that it's not just an inevitability, but it's well on it's way to happening.
I think, despite the protestations of Russia and China, we're going to see a (probably Arab-led) multilateral force deployed in Syria in the relatively near future.
