ANKARA — Turkey's President Tayyip Erdogan said on Thursday that any attack on a Turkish ship exploring for oil and gas in disputed Mediterranean waters would incur a "high price" and suggested Turkey had already acted on that warning.
Tensions in the eastern Mediterranean have risen sharply this week after Turkey sent a survey vessel to the region, escorted by warships, in a move Greece decried as illegal.
"We said that if you attack our Oruc Reis you will pay a high price, and they got their first answer today," Erdogan said in a speech in Ankara without giving details.
The Oruc Reis set out on Monday with its military escort to survey waters between Crete and Cyprus.
In response, President Emmanuel Macron said France would increase its military presence in the region and called on Ankara to stop its exploration work. French and Greek forces held military training exercises off Crete on Thursday.
European Union foreign ministers, who have already imposed sanctions on two Turkish energy executives over Turkey's operations in the eastern Mediterranean, will discuss the situation on Friday.
Greece's foreign ministry said Minister Nikos Dendias will brief E.U. counterparts "about the real facts of the recent days regarding operations in the region" at the emergency meeting.
Erdogan spoke by phone with German Chancellor Angela Merkel and E.U. Council President Charles Michel on Thursday. He "reiterated his commitment to defend Turkey's rights against attempts to disregard them," Erdogan's office said of the call with Michel.
Both Turkey and Greece said this week that they were willing to resolve the dispute over their overlapping maritime claims, but vowed to protect their interests and blamed the other side for the stand-off.
"If we act with common sense and reason, we can find a win-win solution that meets everyone's interests," Erdogan said earlier on Thursday. "We are not chasing any unnecessary adventures or seeking tensions."
In apparent reference to France, Erdogan also said Greece was being pushed into taking "wrong steps" in the region by "a country that doesn't even have a coast in the eastern Mediterranean."
