The actions in Russia were held with the assistance of foreign special services. State Duma’s commission for the protection of state sovereignty has credible data to confirm these statements.
The US Embassy in Moscow in the previous days did everything possible to support, both informationally and politically, the expected events of Saturday’s uncoordinated protests. Their actions were a motivation, a call, an instruction, as well as, an incitement.
Basically, there is nothing new in what is happening. Similar activities from the US and other Western states in relation to Russian domestic political events could be observed over the past decades.
The Russian anti-state opposition, supported from across the ocean [from the US], found itself in the most difficult situation.
While the narrative alleges that the US moved to interfere in Russian domestic affairs and therefore violated Russia's sovereignty, the aforementioned statement, which was published by the US Embassy in Moscow and the US State Department, specifically advised US citizens residing in Russia to stay away from the demonstrations.
The disinformation narrative builds on previous claims alleging that it was not the Russian but Western secret services that are associated with Navalny's poisoning. On December 14, a joint investigative report of CNN, Bellingcat, The Insider Russia and Der Spiegel revealed that the Kremlin-controlled Federal Security Services was behind the poisoning.
