Somali Muslim Pirates capture a Russian oil tanker. Russian Navy commandos quickly free their compatriots and the tanker. They move the pirates back to their own ship, searching for weapons and explosives, leaving the pirates handcuffed to the ship. After the Russians left, they blew up the ship with all the Muslims on it.
The commandos sank the pirate ship along with the pirates and without any court proceedings, lawyers etc. That is, they used the anti-piracy laws of the 18th and 19th centuries where the captain of the rescuing ship has the right to decide what to do with the pirates. Usually, they were hanged.
