 In Tsentoroi (Khosi-Yurt), where the Kadyrovite headquarters is located, there are at least two illegal prisons functioning.One consists of concrete bunkers or pillboxes, where kidnapped relatives of armed Chechen fighters are held hostages while the second prison in Tsentoroi is evidently located in the yard—or in immediate vicinity—of the house of Ramzan Kadyrov.On November 13, 2006, Human Rights Watch published a briefing paper on torture in Chechnya that it had prepared for the 37th session of the United Nations Committee Against Torture.
