With the amount of Syrian/Afghan refugees flooding into Europe right now and Europes involvement in those wars, I imagine this sort of thing is going to be on the rise.
Their involvement in "those wars" being that they had to flee them?
Yes, for the most of the people fleeing that was the sum total of their involvement. And for a small percentage of those people they either are taking the fight with them or have other plans. It's a tough situation, on the one hand no right thinking person has a problem with sheltering refugees, on the other hand those very same people are worried about what the long term consequences of these mass movements of people will be. One thing is fairly certain, the Schengen agreement (which has done more for the unification of Europe than almost any other EU activity short of the launch of the Euro) is going to be a casualty.
