The Turkish navy on Sunday evening issued three navigational (NAVTEX) warnings demanding the demilitarisation of the Greek islands of Samothraki, Lemnos, Chios, Samos, Tilos and Halki.
The move came after European Union leaders last week failed to agree on solid sanctions against Turkey over its actions in the Eastern Mediterranean.
Meanwhile, reports Monday said that the Oruc Reis research vessel has left the port of Antalya and is steering on a southwest course within Turkish territorial waters.
Tensions flared this year after Ankara sent its Oruc Reis seismic survey ship into disputed waters, escorted by gunboats, to map out sea territory for possible oil and gas drilling.
