Several sources report on an incident that happened today during which Turkish fighters entered the area of the Andros firing range where a Greek Navy Frigate was conducting live fire exercises. The Frigate was practicing against an aerial towed target when the Turkish aircraft entered the area.
DefenceNet goes as far as to report that some of the fire nearly hit the Turkish aircraft.
The exercise was halted and the hotline between Larissa and Eski Sehir was activated to deescalate the tension caused. Greek fighters were scrambled to intercept the Turkish aircraft.
Note that the recently uncovered Turkish Military lot against the Islamist government mentioned plans to provoke the shooting down of a Turkish Air Force aircraft by the Greek side in order to rally the people behind the Turkish armed forces.
