Ukraine

Translation using google translate on the image:

At the moment, Ukrainian formations have made another attempt at a massive strike on the Crimean peninsula.
To carry out strikes, both UAVs are used to destroy ground targets, and unmanned boats are used to attack ships of the Black Sea Fleet. Another goal is the Crimean Bridge.

Judging by the explosions in the vicinity of Feodosia, one of the targets could have been the patrol boat "Sergei Kotov", which was in that area. It is unknown whether there were hits or whether explosions occurred as a result of the destruction of the BECs.
