Four Greek F-16 fighter jets harassed the TCG Cesme south of the Greek island of Lemnos, with one of them dropping a flare 2 nautical miles (3.7 kilometres) from the vessel.

Axar.az reports citing Anadolu Agency that Turkey’s military retaliated but it did not say how or when the incident took place.

“It was an act of harassment, which our Greek neighbours carry out frequently,” Anadolu quoted Turkish Defense Minister Hulusi Akar as saying. “We gave the necessary response in line with rules.”

There was no immediate comment from Greece.
