The European Union should establish a new frontier on the northern border of Greece, because an agreement with Turkey will not be sufficient to stop hundreds of thousands of migrants from entering Europe, Hungarian Prime Minister Viktor Orban said.

Orban has gained support in Hungary due to his tough stance on migration, while his government has raised fences on the country’s southern border to keep out migrants and asylum seekers.

Initially, this move drew criticism from his European Union partners, but many countries, such as Slovenia and Austria, have also raised barriers to their borders, while others have imposed security checks within the EU’s border-free Schengen zone to cope with the flow.

As Reuters reports, Orban said Germany, which received millions of migrants last year, has recently changed its stance wishing to control the refugee and migrant flow

“I think the next line of defense that we need to build up lies on the northern border of Greece,” Orban told public radio in an interview.

He said Bulgaria, one of Greece’s northern neighbors, should be adopted into the EU’s border-free Schengen zone, while FYROM should be given financial aid to beef up its defenses.

“I do not think that the deal with Turkey will be sufficient in itself,” Orban said.

“It is nice that (Turkey) has promised that there would be a line of defense there, but we need to build one of our own from our own resources on the northern border of Greece and stop, not slow down, but stop migration,” Orban said.
