A plane carrying Russian President Vladimir Putin made a 300 mile detour to avoid flying over Poland and the Baltic States on his way to the G20 summit.
According to the FlightRadar24 website, the Russian government jet flying from Moscow to Hamburg on Thursday deviated from the direct route over Belarus and Poland.
Poland and the Baltic states of Lithuania, Latvia and Estonia have been particularly vocal in their criticism of Moscow since Russia annexed Crimea from Ukraine in 2014.
The Ilyushin with the registration number RA-96022 flew over the Baltic Sea, crossing on its way territory of neutral Finland and Sweden before making its final approach to Germany.
Kremlin spokesman Dmitry Peskov declined to comment on the reasons for the detour.
