According to the Russians, there were 3 vessels attacking their ship. For some reason there's only video of one. I think it's safe to assume the ship did not sink, since someone took the time to upload a video.
According to russian MoD this was about 140km north of the Bosporus Strait.
Ru MoD claims the ship was roughly 140km north of Bosporus Strait which is about the same distance from Ukraine as Simferopol. They claim it was there to protect a pipeline (in green).
People ask why do it daytime?
Propaganda value of a burning and sinking Russian ship maybe.
Sinking this ship would probably not change a lot for Ukraine. I would think the biggest benefit would be the propaganda value.
There's starting to be a slight uncomfortable feeling in the Russian telegram channels. The last few days there have been reports about a "river" crossing close to Velyka Novosilka. There are also some local counter attacks with success in the Bakhmut area.
In addition to that, there are very recent Russian telegram reports of Ukrainian offensives in the Soledar and Mayorsk area.
It seems units of the RU 3rd Army Corps have been holding the line in the area SW of Bakhmut. These are rapidly trained personnel which were recruited last summer. Their losses are now being replaced by mobik regiments. I think it's likely Azov will eat them for breakfast.
I discussed this yesterday with a few guys on my discord. Our conclusion was those are Leopard 2R mine clearing vehicles. We based that on the bulky camera and lack of main gun.
