Greece has installed a 40km (25-mile) fence and surveillance system on its border with Turkey amid concern over a surge of migrants from Afghanistan.
“We cannot wait, passively, for the possible impact,” Greece’s Citizens’ Protection Minister Michalis Chrisochoidis said.
“Our borders will remain inviolable.” Mr Chrisochoidis continued.
His comments came as Turkey called on European countries to take responsibility for Afghan migrants.
“A new wave of migration is inevitable if the necessary measures are not taken in Afghanistan and in Iran,” Turkish President Recep Tayyip Erdogan said in a statement.
Greece, which was on the frontline of the migrant crisis in 2015 when more than a million people fleeing war and poverty in the Middle East crossed from Turkey into the EU, has said it may send back any Afghans that arrive illegally through the country.
Greek Prime Minister Kyriakos Mitsotakis said at the time that Greece had increased “the level of deterrence at our borders to the maximum”, with security personnel deployed to the Evros land border.
