Also, if you've been paying attention to sources of information other than the MSM, you'll know that for the last six months, ISIS has been confiscating passports in places like Mosul, Aleppo and Raqqa. This information has come from many sources inside the occupied cities. Once these murderers realized that their overthrow was inevitable they started planning escape to the West. In fact Baghdadi in his last tape ordered exactly that - that his followers who could no longer help in the defence of the cities return to their homelands or the West to cause mayhem there.
The bottom line is that papers and passports can no longer be trusted.
