Earlier, the Russian National carrier, Aeroflot flights were banned in the UK as part of sanctions that also targeting VTB and state owned company Rostec linked with Russian invation in Ukraine. PM Boris Johnson said the move sought to "squeeze Russia from the global economy".
Russia has restricted flights to Bulgarian, Polish and Czech airlines in its airspace in response to similar moves taked by those countries, the Russian civil aviation authority, Rosaviatsiya, said on Saturday.
The restrictions entered into action at 12:00 GMT on 26 February in connection with "unfriendly decisions of the aviation authorities of Bulgaria, Poland and Czech Repabulic regarding the closure of their airspace," reads a statement by Rosaviatsiya.
The restrictions in question concern any flights to airports in Russia or through Russian airspace. Flights from these countries may only be carried out with authorisation from Rosaviatsiya or the Russian Foreign Ministry.
