"The walls and fences take us back to the deeply divided postwar Europe of the past," EU Commissioner for Migration Dimitris Avramopoulos on Sunday said in an interview with Realnews newspaper.

"The most important element of the new European Border and Coast Guard Agency is that it goes beyond what Frontex was able to do, but that we do not replace member states' responsibilities and definitely not their sovereignty," European Commissioner for Migration and Internal Affairs Dimitris Avramopoulos said in the European Parliament Plenary session on the European Border and Coast Guard.
