500 refugees have blocked part of both directions of the Thessaloniki-Evzones national highway in northern Greece, demanding the opening up of the orders between Greece and FYROM. The refugees are occupying the highway at the Polycastro area which has caused a traffic jam. It remains unclear when the road will open, as they are walking on the highway with banners and chanting for the northern borders to open. Nearly 13,000 refugees saw their journey through Greece to the north of Europe stopped when the Balkan route was closed when countries to the north of Greece decided to seal off their borders.
