Two ferries left Greece for Turkey Tuesday with 18 migrants on board, as a government spokesman said Athens was doing all it could to process returnees under a deal with Turkey intended to stem a huge refugee influx into Europe.
Just over 340 people have so far been returned to Turkey under the accord, agreed with the European Union in March after more than 1 million people fleeing war and poverty in the Middle East and beyond reached the continent last year.
On Tuesday, 13 people were deported from the island of Lesbos to the Turkish town of Dikili and five were ferried back from Chios to Cesme, police said. Most were Afghans.
None had requested asylum in Greece, a government official said.
