EU chief warns economic migrants not to travel to Europe

The process of making that distinction is burdening resources, said Ian Bond of the London-based Centre for European Reform. "It's the sheer effort of trying to separate the legitimate refugees from those who are just economic migrants, which I think is really overwhelming the resources that Greece and its EU partners have been able to put into the problem at the moment," Bond said.

..."It is quite clear that Russia is exploiting the refugee crisis to divide Europe," said Bond, of the CER.
