Greece is protesting Turkey's move to reserve a large chunk of airspace over the Aegean Sea for military maneuvers until the end of the year, a Greek foreign ministry spokesman says.

Foreign Ministry spokesman Constantinos Koutras says Turkey has unilaterally issued a Notice to Airmen, or NOTAM, reserving an extensive airspace over the Aegean Sea from March 2 to December 31, 2015, for military use.

Greece says the move intrudes into Greek airspace, interferes with traffic to two regional airports and affects two international traffic routes.

Greece's civil aviation authority has issued a navigational warning stating the Turkish NOTAM is null and void.

Koutras says Greece will take the matter to NATO, the United Nations, the European Union and the International Civil Aviation Authority (ICAO).
