A service of the Turkish Navy has issued a NAVTEX claiming that the Greek islands of Chios, Psara and Samos are violating the 1923 Treaty of Lausanne.

The first report by Turkey’s Service of Navigation, Hydrographic and Oceanographic Research was issued on 30 April, and a second one followed on the 15 May.

It is claimed that the Greek islands are in violation of the demilitarised status which is required by the 1923 Peace Treaty.

Specifically, Greece had conducted exercises in Samothrace on 4 May, in Lemnos on 6 and 20 May and west of Psara on 5 May.

Turkey issued a NAVTEX on Thursday night accusing Greece of violating the treaty.

The Treaty of Lausanne was a peace treaty negotiated during the Lausanne Conference of 1922-1923. It officially settled the conflict that had originally existed between the Ottoman Empire and the Allied French Republic, British Empire, Kingdom of Italy, Empire of Japan, Kingdom of Greece, and the Kingdom of Romania since the onset of World War I. The Treaty of Lausanne ended the conflict and defined the borders of the modern Turkish Republic. In the treaty, Turkey gave up all claims to the remainder of the Ottoman Empire and in return the Allies recognised Turkish sovereignty within its new borders.
