-- AFP PICTURES OF THE YEAR 2015 -- Migrants and refugees wait at Istanbul's Esenler Bus Terminal for buses to the Turkish-Greek border after authorities withheld tickets to Turkish border towns on September 16, 2015. Hundreds of refugees camped out at the main bus station in Istanbul for a second night running after being refused tickets for Edirne, some 250 kilometres (150 miles) away. Many of the refugees seeking to leave Turkey have been living in the country for months, sometimes years, after fleeing the bloody civil war in neighbouring Syria. AFP PHOTO / YASIN AKGUL
