This was reported by Ukrainian and Russian media. According to the Ukrainian media, the ship was sunk, but there is no confirmation of this information yet.
Telegram channel “Crimean wind” published several videos allegedly, the first video shows a burning Russian ship, and the second shows a column of smoke and sounds of explosions from the allegedly ammunition of the BLS. It is not yet possible to confirm or deny the veracity of these videos.
This is at least the fifth Russian BLS that has been hit since the beginning of the war.
By the way, the USSR hero Caesar Kunikov, after whom the ship was named, died on February 14, 1943.
