One of the Russian mines brought to the Bosphorus, which the racists mined the sea routes around Ukraine, fearing the arrival of NATO ships.
Turkey's Ministry of National Defense has closed the straits to clear the mine. After the work of the sappers, navigation through the strait was restored. According to Turkish authorities, it was an old-fashioned floating mine. Russian sources reported the deployment of 420 mines around Ukraine.
We remind you that Russia is now throwing out all the military equipment it has. Therefore, there may be even such warlike historical examples as, for example, the gravel of the 1800s.
