The European Union will Wednesday announce plans for emergency aid to Greece which is struggling to cope with an influx of migrants with thousands stuck in misery at its border after Balkan states tightened their frontiers.
Greece has asked for around 480 million euros to help shelter 100,000 refugees as Europe faces its biggest wave of refugees since World War II in a crisis that has sown deep discord and threatened the bloc's solidarity.
NATO's top General Philip Breedlove warned that the massive flow of people into the EU particularly from war-torn Syria has had a destabilising effect.
He specifically pointed the finger of blame at Syria's President Bashar al-Assad and his backer Russia, accusing them of turning the migrant crisis into a "weapon" against the West.
