As is clear, Russia is essentially accusing the two tech giants of interfering in its elections.
Russia has enacted laws banning political advertising "during elections on Sunday and the day before," according to Reuters. Russia's Roskomnadzor, the government body that oversees the country's media laws, said Facebook and Google had posted ads during Sunday's election.
Google and Facebook did not immediately respond to Russia's accusations.
Of course, Facebook has spent the last two years eradicating Russian-backed propaganda and other "coordinated non-authentic behavior" in platform since the country's improper use of social media during the 2016 US presidential election. Since then, Facebook has discovered several other networks - from Russia and other countries - that have attempted to manipulate social media users.
