Russia issued a formal maritime warning saying that a number of naval mines that were placed in the Black Sea—allegedly by Ukrainians in efforts to counter Moscow’s invasion—are no longer attached to their anchors and could drift toward the Straits of Bosphorus and the Mediterranean Sea.
In a press statement on Saturday, Russia’s Federal Security Service (FSB) said that Ukrainian naval forces had placed lines of mines near the ports of Odessa, Ochakov, Chernomorsk, and Yuzhny, reported state-run news agency TASS. The FSB said the mines were made in the first half of the 20th century by the Soviet Union.
