Previously there were reports that the Russians forced the ship to cover them as "human shield": https://www.jpost.com/international/article-699109
I also would be careful with AIS data right now, it's easy to spoof and has been done so very recently in the black sea (https://www.maritime-executive.com/article/hackers-deface-ai...)
For instance, Ukrainian military claimed that tank that drove over civilian car in Kyiv was Russian, but it was Ukrainian.
IIRC, they claimed that it was an Ukrainian Strela-10 that was captured by an illegal combatant. Regardless, I just wanted to point at that piece of information without claiming that it was true.
