ATHENS – Greek F-16 fighter jet returned to Larissa home base on Tuesday after making the first patrol over North Macedonia’s sky as part of the agreement that North Macedonia’s air space will be guarded by Greece, reports Kathimerini. The purpose of the mission was to locate any radar blank sectors and to test the compatibility of reconnaissance systems. In the future, Greek planes will continue their patrols over North Macedonia. Surveillance of North Macedonia’s air space was part of the the Prespa Agreement signed between Athens and Skopje last summer, and has been part of NATO policy for the past 12 years. Greece already conducts surveillance over Montenegro and Albania.
