The Russian military command for the first time announced that in the war with Ukraine, it used a submarine fleet to strike at the enemy, reports Voice of America..

The Russian Defense Ministry said in a statement that ground targets in Ukraine this week were hit by Kalibr cruise missiles launched from a diesel submarine in the Black Sea.. The statement was accompanied by the publication of video footage showing rockets taking off directly from under the water at an unspecified location..

Western experts are concerned that every time the parties use new types of weapons during the course of the war, this could mean the risk of a significant escalation of the conflict..

The British Ministry of Defense confirmed two days ago that the Russian Black Sea Fleet, despite the decommissioning of the Moskva flagship cruiser, still has the potential to strike ground targets in Ukraine..

According to British estimates, about 20 ships and submarines of the Russian Navy are now on combat duty in the Black Sea.. However, as the Ministry of Defense of the United Kingdom noted, Russia now has no opportunity to replenish this flotilla, since the Bosphorus Strait, which connects the Black Sea with the Mediterranean, is closed to the passage of any military vessels, except Turkish.
