Turkey's President Recep Tayyip Erdoğan said on Friday that Turkey had resumed drilling operations in the eastern Mediterranean as Greece had not kept its promises regarding energy exploration in the region.
NATO allies Turkey and Greece have long been at loggerheads over overlapping claims for hydrocarbon resources and tensions have flared up between them again.
Erdoğan was speaking to reporters after Friday prayers at the Hagia Sophia mosque.
He said Turkey's Barbaros Hayreddin Paşa, a seismic survey vessel, had been sent to the region to carry out its duties. The ship moved into waters off Cyprus in late July and remains in that region.
