At least six Turkish fighter jets, flying in a single formation, violated Greek airspace, local media reported, citing military officials.

MOSCOW (Sputnik) — Turkish aircraft entered Greek airspace in the northeastern part of the Aegean Sea without Athens’ permission, the Ekathimerini newspaper reported Tuesday, citing country’s military authorities.

At least two of the six fighter jets were armed, the newspaper added.

Turkey does not recognize a 10-mile zone of Greek airspace surrounding islands in the Aegean Sea that are the cause of numerous similar incidents in the sky over the sea.
