The fate of Vladimir Putin 's Black Fleet chief, Igor Osipov, is reportedly shrouded in mystery after it emerged that the Admiral has "not been seen alive" since the sinking of the Moskva warship last month.
Sources in Kyiv say there are suspicions he was on board the vessel when it was hit by Ukrainian coastal defence missiles.
Russia has so far admitted to one fatality on the Moskva, but it is clear many more were killed. It is also unclear how many were wounded and where they might be receiving treatment as a consequence.
