Greece Puts Navy on Alert as Turkey Tensions Flare Again Anthee Carassava ATHENS, GREECE - Greece's navy has issued a code orange alert, advising battleships to surround a cluster of tiny islands in the southeast Aegean Sea and prepare for potential hostile action from Turkey. The dangerous standoff is further complicating efforts by the United States and the European Union to get the two sides to negotiate a maritime settlement. Greece's defense ministry on Wednesday released pictures of what Greek officials called a "protective wall," illustrating what it called the severity of the looming standoff with Turkey. Military officials tell VOA Greek gunboats circled the Kastellorizo and a number of uninhabited islands, in a move they said is meant to shield Greek territory against Turkish attempts to survey disputed waters for oil and gas. Ankara redeployed the Oruc Reis survey ship earlier this month just weeks after it had recalled it from a similar mission that nearly brought Greece and Turkey to the brink of war over energy rights in the eastern Mediterranean. .
