According to the published press release, the banned list includes aircraft from Russia, Ukraine, Belarus, and Moldova. In turn, Greek aircraft are not allowed to fly over the territories of these countries.
The new rules will be in effect for at least another month, until about the end of June.
This is just one of the latest sanctions that continue to be applied to Russia. In particular, Denmark and Sweden previously reported that they had summoned Russian ambassadors in connection with a potential violation of their airspace by Russian aircraft.
Danish Foreign Minister Jeppe Koford said a Russian plane had intruded into Danish airspace over the island of Bornholm. Sweden, which formally applied to join NATO along with Finland earlier this month, also said a Russian spy plane had crossed its airspace.
