Migrants from Afghanistan try to warm upon their arrival at the village of Skala Sikaminias, on the Greek island of Lesbos, after crossing the Aegean sea from Turkey, on Friday, Feb. 28, 2020. NATO envoys held emergency talks at the request of Turkey, a NATO member, and scores of migrants began converging on Turkey's border with Greece seeking entry into Europe after Turkey said it was "no longer able to hold refugees."
