Athens: Greece said on Monday that Turkey plans to carry out a maritime military exercise on October 28, a Greek national holiday, just hours after NATO's secretary-general said both Greece and Turkey had called off wargames on each other's national holidays.
Government spokesman Stelios Petsas said Ankara's move showed it was an unreliable partner when it comes to negotiations.
Over the last few days, Turkey has been making a persistent effort to prove that not only is it a troublemaker in our wider region, but it is also a completely unreliable interlocutor, Petsas said.
Turkey has sent a seismic research vessel, the Oruc Reis, to prospect for energy reserves on the seabed in an area Greece that claims is on its own continental shelf and where it has exclusive economic rights. Turkey disputes the claim.
