The Permanent Representative of the Republic of Crimea to Russian President Vladimir Putin and former Russian Ambassador to Cyprus Georgiy Lvovich Muradov has warned Greece against transferring S-300s to Ukraine.His warning comes after Greek National Defence Minister Nikos Panayiotopoulos admitted that the Greek government was ready to send the S-300 air defence systems from Crete to Ukraine if the USA “installs Patriot systems in their place”.Speaking to Russian media outlet RIA Novosti, Muradov said: “Such a move by Athens would not only be a senseless demonstration of hostility towards Russia, but also a risky step towards its own national interests, as the Greek public is already loudly declaring.“However, transferring these systems to Kyiv would undoubtedly radically undermine the Greek defence potential.”RIA noted that since the 1990s, Greece has been using Russian anti-aircraft missile systems S-300 (S-300PMU-1) and Tor-M1, military anti-aircraft missile systems “Osa-AKM” (NATO classification SA-8 Gecko “Gecko”), antitank missile systems “Kornet-E” and “Fagot”, amphibious hovercraft crafts “Zubr” and armoured infantry vehicles.READ MORE: Eurobarometer: Greece has the lowest support for Ukraine in the EU."
