Abu Salim prison (Arabic: سجن أبو سليم, romanized: Sijn Abū Salīm) is a maximum security prison in Tripoli, Libya. The prison was notorious during the rule of Muammar Gaddafi for alleged mistreatment and human rights abuses, including a massacre in 1996 in which Human Rights Watch estimated that 1,270 prisoners were killed. In 2011, when the National Transitional Council invited investigators from CNN and other organizations, it found only what appeared to be animal bones at that site and announced further investigations.
