Greece has persuaded Turkey to accept migrant returns from the mainland in order to reduce critical overcrowding in its refugee camps, a report said on Saturday (Dec 9).
The Kathimerini daily said the agreement came during a two-day state visit by Turkish President Recep Tayyip Erdogan this week.
The deal is in addition to Turkey's existing agreement to take back migrants from Aegean island camps, under the terms of an EU-Turkey pact.
Greek Prime Minister Alexis Tsipras' office did not respond to AFP requests for comment on the report.
But a Greek government source on Friday said Athens and Ankara had agreed "new measures of cooperation towards decongesting the islands, under the terms of the EU-Turkey pact."
No further details were given.
