“The Russian Navy Ochakov Kara-class cruiser was sunk . . . to blockade the Ukrainian Navy ships deployed in Novoozerne,” The Ukrainian Ministry of Defense said in a statement. “The Russian military towed and put in the navigating channel their ship Ochakov. They filled her with water. Then, there was some explosion."The sunken vessel will be a really big obstacle for other ships to leave the Donuzlav Lake because the water depth in the area is about 9-11 meters.
