"The Schengen Treaty is founded on the principles of solidarity and responsibility.
Any effort to cast this into doubt, casts these principles into doubt and this does not benefit anyone nor does it offer any solutions," EU Commissioner for Migration and Internal Affairs Dimitris Avramopoulos said in a statement to "Kathimerini" newspaper.
The Commissioner noted that "the refugee crisis we are facing is unprecedented. And this does not only regard the host countries or the destination countries, but all Europe," adding that "despite the strong pressure on Greece, it is imperative to complete this effort that will give tangible results."
According to Avramopoulos, "the immediate and full implementation of the agreed measures, both in Greece and in all the member states, will strengthen the security of maritime boundaries and will restore control in the northern border, where non-unidentified migrants try to continue their trip to the north."
