Add to that cyberattack on the airports 3 days ago and now massive drones in European airports (when Russia has been for several months having its own airports periodically shut down by Ukranian drones and thus clearly understood such an action and how it can be used in a hybrid war and also how it can hint at capability to perform a "Pautina"(SpiderWeb) style operation against Europe) - what are the chances for the drones to not be Russian. And not forgetting cyberattack on the airports 3 days ago.
