Russia has closed its airspace to airline carriers from 36 nations, including European countries and Canada.
The ban was a response in kind to their earlier move to close their respective airspaces to all Russian aircraft.
The move, announced Monday by the State aviation agency, follows a decision by the EU and Canada over the weekend to close their skies to the Russian planes in response to Moscow’s invasion of Ukraine.
It added that planes from those countries could only enter Russia’s airspace with special permission.
