No, but it doesn't take a genius to know that the foreign fighters are coming from Syria. We have shifted a vast amount of resources and forces to the Anbar and western province. Sunni terrorist groups, mainly Al-Qaeda and Ansar Sunnah are being sheltered in Syria. They have unfettered access to and from Iraq via Syria. I would be harsh on Iran for supplying the Shiiate militias... but to be honest most of the jihadis are flowing in from Syria.
