I`d be cautious with making conclusions nowadays. With the amount of fake news and provocations, I wouldn`t be surprised if it was Ukraine`s masterplan.
After all, it looks too suspicious: there is president elections in Ukraine soon, and it`s not allowed to elect the new president during state of defense situation. It could as well be a political move and very skillful usage of the current political situation by Ukraine`s government
Uhhh.... how would that remotely be true? It's be collaborated by several different nations. There's actual pictures from the BBC that shows that the boat blockaded actually exists.
In reality, this is Russia trying to spread misinformation regarding the situation by saying "UKRAINE IS AT FAULT FOR OUR ACTS OF AGGRESSION"
