Hungary's Prime Minister Viktor Orban has said that the EU needs a fence along Greece’s borders with Macedonia and Bulgaria to cope with the ongoing migrant influx and save the bloc’s Schengen area of passport-free travel.

"If we cannot secure the outer border (of the EU), regardless of how costly or demanding that is, we will destroy the Schengen regime by ourselves," Reuters quoted Orban as saying during a visit to Slovenia on Friday .

Two weeks ago, Orban told Hungary’s public radio that Bulgaria, which is bordering Greece to the north, should be admitted into Schengen Area because the EU’s deal with Turkey to stem the flow of migrants into Europe in exchange for possible financial aid of EUR 3 B wouldn’t be enough to deter migrant pressure.

Hungary's Foreign Minister Peter Szijjarto has also called for talks with Bulgaria and Macedonia to curb the migrant inflow as the EU’s southern frontiers– and particularly Greece’s long maritime border - were still wide open to the ongoing influx of migrants and refugees from the Middle East and Africa.
