The caption says capture of pirates by Russian vessel "Adm Panteleeb", It says that it is real. The BPK are Large Anti-Sub ships.
With the guy on the deck
bleeding they are calling for a doctor.
Looking over the weapons they note that they were NOT Russian AK47.
At night they are taking an inventory of all the guns
and things taken.
They were sorting the people by national origin.
When they blow up the pirate ship they were making fun of the small boat crew who put explosives on it (you can see the boat inthe video) - What that is all? Then when the second explosion went (and boy did it go) that said that this is better.
They did note these were the same pirates who were attacking a Russian freighter a few days earlier.
There is more but that is the gist of it.
