Greece estimates that more than 25,000 migrants are presently on its territory, with more than half stuck at the makeshift camp Idomeni, on the border with Macedonia. The EU and Turkey have agreed in principle on a scheme to return migrants from Greece to Turkey and directly resettle legitimate Syrian refugees across the bloc directly from Turkey. The deal would likely only apply to new arrivals, making the future of those already in Greece unclear. The agreement has practically closed the so-called Western Balkans route from Greece into Macedonia, Serbia, Croatia, Slovenia, Austria and then Germany.
