ATHENS — Going back-and-forth between diplomacy and tough talk, Turkey now said the Greece violated an agreement not to old military exercises in the Aegean during the summer when both countries are trying to attract tourists.

Turkey's Foreign Ministry said it would stick to the deal but that it “should not be expected to watch Greece violate the deal outright with its hands tied,” saying Greece authorized a training exercise for the sea that separates the countries.

The statement was tweeted by Turkish media accounts, followed by Turkey issuing its own NAVTEX (Navigational Telex) for exercises, warning other vessels to steer clear of the area it's reserving.

Turkey and Greece have been at loggerheads over rights to the Aegean and East Mediterranean for energy hunts and drilling, several times bringing them to a near-conflict point before the tension was ratcheted down after a meeting of Prime Minister Kyriakos Mitsotakis and Turkish President Recep Tayyip Erdogan in Athens at a NATO meeting.
