PIRAEUS, GREECE - FEBRUARY 27: Migrants become stranded at Piraeus after border closures on February 27, 2016 in Piraeus, Greece. Officials have said around 20,000 thousand migrants have been stranded in Athens and at the country's border with Macedonia, after the Balkan state tightened border controls denying all passage to Afghans and also ramping up document controls for Syrians and Iraqis. Greece has temporarily suspended all ferries transporting migrants and refugees from the islands to ease congestion on the mainland. (Photo by Awakening/Getty Images)
