Greece may file an official protest to Turkey over a dangerously low overflight of Turkish fighter jets above a Greek frigate in international waters, the Greek military said.
The move comes in the wake of Greece's dismissal of the Turkish proposal to disarm warplanes that patrol the Aegean Sea, RIA Novosti reported.
According to a report by the Greek Navy, two Turkish F-4 Phantom interceptor/fighter jets flew 150 meters (500 feet) above the Salamis frigate, which took part in military drills between the islands of Chios and Samos in the eastern part of the Aegean Sea.
A formation of seven Turkish aircraft was spotted near the Greek frigate, the Navy said.
Though ties between the two NATO allies improved over past decades, the long-standing dispute over territorial waters and airspace boundaries in the Aegean Sea still remains a bone of contention in bilateral relations.
Greece often sends its warplanes to intercept Turkish aircraft which fly in the zones over which Greece claims control, with mock dogfights occurring now and then. In 2006 a Greek pilot was killed in a mid-air collision with a Turkish jet.
