Russia's Foreign Ministry said on its website on the 4th that Ukraine's notice about Russian airspace “no longer being safe” distorted the facts and misled users of Russian airspace. According to Sina Finance, the ministry said the Ukrainian remarks posed a direct threat to civil aviation, that Russian authorities were maintaining contact with the International Civil Aviation Organization, and that an urgent appeal had been sent to the ICAO secretary-general.
The ministry said Russia has always firmly safeguarded civil aviation safety. According to Sina Finance, Ukraine said on the 1st that U.S. President Donald Trump warned international airlines in an evening address that Russian airspace was becoming dangerous, while Russian Transport Minister Nikitin said on the 2nd that the transport ministry was continuing to raise flight safety and airport security requirements and that Russia had the ability to respond to all threats.
