HAHAHAHAHHA that translation
That symbol flag on the wall as well as on the torturers arms is that of the PKK (Kurdistan Workers' Party). While some members might be muslims since most kurds are muslims, Islam is nowhere on their party's agenda. They subscribe to left economic ideologies of socialism, as well as ethnic separatism by wanting ethnic kurdish territories to secede from Turkey and form their own independent nation. They are classified as terrosist group in many nations due to their involvement in organized crime and terrorism to achieve their political goals, both in Turkey and abroad. What this video shows is most likely the PKK "punishing" someone who opposed or they suspect of opposing them politicaly or pragmatically in one way or another, and has nothing to do with religious rite of punishment.
