Government spokesman Kyriakos Koushos said that although Cypriot authorities don't have definitive proof, it's believed that Turkey got its hands on data that helped guide its drill ship to the specific target.
The location is in an area, or block, where Cyprus has licensed Italy's Eni and Total of France to carry out a hydrocarbons search. The two companies are licensed to conduct exploratory drilling in seven of Cyprus' 13 blocks that make up its exclusive economic zone.
“There's information, which is probably correct, that they had stolen plans and studies from a specific company, that's why they went to the specific spot," Koushos told Greece's state broadcaster ERT.
The Cypriot official said wasn't suggesting that either Eni or Total handed Turkey the data. Koushos repeated that Turkey continues to flout international law by carrying on with illegal drilling activity in Cypriot waters and accused the country of “gunboat diplomacy.”
“Unfortunately, Turkey has become the pirate state of the east Mediterranean," he said. This would be the fourth location inside Cyprus' economic zone that Turkey is looking to drill since July. Turkey has dispatched warship-escorted drill ships to drilling targets to the east and west of the island nation.
Koushos denied a Turkish claim that it's in secret negotiations with Eni on a hydrocarbons search in the area. Cypriot Foreign Minister Nikos Christodoulides said Wednesday that the European Union is moving to expedite sanctions against individuals or companies involved in illegal drilling off Cyprus.
Turkey insists that it's acting to protect its interests, and those of breakaway Turkish Cypriots, in the region's energy reserves. It says part of Cyprus' economic zone falls within its own continental shelf and that its drilling activities are also part of a deal with Turkish Cypriots.
The U.S. State Department said Washington remains “deeply concerned” over reports that Turkey is moving to drill south of Cyprus, urging Turkish authorities to halt its “provocative step that raises tensions in the region.”
The State Department reiterated U.S. support for Cyprus' sovereign right to develop resources inside its exclusive economic zone and a deal that would allow Greek Cypriots and Turkish Cypriots to equitably share in potential gas riches.
Turkish Cypriots say they're unfairly being left out of the gas search and are entitled to a share of any revenues. The Cypriot government says the Turkish Cypriots' share of such wealth is guaranteed under an energy fund into which all future hydrocarbon revenues will flow and will be split after a deal reunifying the island is achieved.
Cyprus was divided along ethnic lines in 1974 when Turkey invaded following a coup by supporters of union with Greece. A Turkish Cypriot declaration of independence in the island's northern third is recognized only by Turkey. Cyprus joined the EU in 2004, but only the southern part, seat of the island's internationally-recognized government, enjoys membership.
Other companies Cyprus has licensed to carry out a hydrocarbons search include ExxonMobil and partner Qatar Petroleum, as well as Texas-based Noble Energy and partners Delek of Israel and Dutch Shell.
So far three gas deposits have been discovered off Cyprus' southern coastline.
