Newly arriving refugees walk towards the Greek-Macedonian border near the Greek village of Idomeni, on March 4, 2016, where thousands of migrants and refugees are stranded. As the diplomatic efforts went into high gear ahead of a March 7 summit between the EU and Turkey, the human misery along the Greek-Macedonia border worsened after a night of driving rain and plummeting temperatures. The humanitarian crisis is particularly acute at the Idomeni crossing where around 12,000 people are stranded after Austria and the Balkan states imposed a cap on entries, triggering a rapidly-growing buildup in Greece. / AFP / LOUISA GOULIAMAKI
