Sixty-three foreign nationals were arrested in the early morning hours of Saturday on charges of illegally trying to exit the country, after a crowded sailboat carrying the group was located just off southwest Greece in the Kyparissia region.
Another man, a 35-year-old Turkish citizen was arrested aboard the Turkish-flagged vessel on migrant smuggling charges, along with a Greek national on shore, identified as a 55-year-old truck driver.
Coast guard authorities believe the vessel was transporting illegal migrants to Italy.
No information was given on the nationalities of the detained people.
