Authorities have retrieved 12 dead near Turkey's border with Greece, according to Turkey's interior minister. The bodies are likely to be those of migrants who died of frostbite after being driven back into Turkey.
The 12 were among 22 migrants driven back into Turkey by Greek border guards, according to Interior Minister Suleyman Soylu.
"They were discovered without shoes and stripped of their clothes at the Ipsala border crossing between Turkey and Greece, he said.
The minister didn't go into detail, but he criticised Greek border guards of being "brutal" and the European Union of being "soft" on Greece.
Turkey routinely accuses neighbouring Greece of illegally rebuffing migrants attempting to enter Europe. Greece refutes the charge.
Turkey is a major transit hub for migrants seeking a better life in European Union countries from the Middle East, Asia, and Africa.
The majority attempt to enter Greece by crossing the northern land border or packing into smuggling boats bound for the Aegean Sea's eastern islands.
