IDOMENI, GREECE - DECEMBER 4: Refugees wait to pass through a Greek police cordon before crossing the Greek-Macedonian border on December 4, 2015 near the village of Idomeni, Greece. Macedonian authorities are now only allowing migrants from Syria, Iraq and Afghanistan to cross the border from Greece, which has led to protests by refugees from other countries who have blocked the border crossing since Wednesday.
