Фейк The Sea of Azov became an exclusively internal sea of Russia
Russian mass media spread such information. This happened allegedly after the Donetsk, Luhansk, Zaporizhzhia, and Kherson regions "joined" Russia.
The so-called "referendums" were held in the four temporarily occupied regions of Ukraine and were not recognized by any democratic country in the world. People who didn`t evacuate from these regions were forced to participate in pseudo-referendums by blackmail and threats, and sometimes at gunpoint. Their "results" don`t reflect the will of the Ukrainians.
These pseudo-votes don`t change the borders of Ukraine, and the "temporarily occupied" status of several Ukrainian territories doesn`t deprive Ukraine of the right to use the internal seas.
