What happened
The Russian Foreign Ministry issued a statement on September 4 rejecting Ukraine's navigation notice that claimed Russian airspace is no longer safe, calling it a distortion of facts and an attempt to mislead airspace users.
The ministry said Ukraine's remarks constitute a direct threat to civil aviation and announced that Russian authorities are in contact with the International Civil Aviation Organization, having sent an urgent appeal to its secretary general.
The statement follows Ukrainian President Volodymyr Zelensky's late-night address on September 1 warning international airlines about the dangers of Russian airspace, and a September 2 remark by Russian Transport Minister Nikitin that Moscow is steadily improving flight safety and airport security requirements and can handle any threats.
Why it matters
The dispute escalates a public confrontation between Kyiv and Moscow over airspace safety, which could influence how international carriers assess flight routes near or over Russia.
Russia's move to involve the International Civil Aviation Organization suggests it is trying to counter Ukraine's narrative through diplomatic channels and reassure the global aviation community of its commitment to civil aviation safety.
