I make no claims to the authenticity of this video. I am not certain of the context. It is mostly is Russian (with much NSFW language), partly in English (with NSFW language) and shows several obviously wounded men.
The explosion at the end is nice though!
From the description at You Tube:
Yesterday on Tuesday (27 April) at 1812 Moscow time the large antisubmarine ship Admiral Panteleyev captured a pirate ship off of Somalia according to the Ministry of Defense.
The capture took place at 1812 Moscow time and took place about 15 miles from shore. Inspection of the vessel revealed seven Kalashnikovs, pistols, aluminum boarding ladders, navigation equipment, including satellite navigation, fuel cans and ammunition.
Twenty nine were detained.
Based on the number of pirates in this video, I don't think these were the pirates killed under the auspices of Russia's "catch and release" program.
