Sept 4 — The Russian Foreign Ministry said on its website it has filed a formal
protest against Ukraine's navigation notice that the "Russian airspace is no
longer safe", calling the notice a distortion that misleads airspace users.
Moscow said the Ukrainian statement poses a direct threat to civil aviation,
that Russian authorities are in contact with the International Civil Aviation
Organization (ICAO) and have issued an urgent appeal to the ICAO
secretary-general, and reiterated it will continue to safeguard civil aviation
safety.
