Greece Turkey Erdogan

Kurdish demonstrators burn placards with pictures of Turkey's President Recep Tayyip Erdogan, as they stage a protest against his visit in Athens, Thursday, Dec. 7, 2017. Many sources of tension remain between Greece and Turkey, neighbours with historically fragile relations who have come to the brink of war three times since the 1970s. Decades-old thorny issues include territorial disputes in the Aegean, the Muslim minority in northeastern Greece and the continued occupation by Turkish troops of northern Cyprus.
