Libyan jail symbolises horror of Gaddafi era
Under the rule of the late Colonel Muammar Gaddafi, the most feared places in Libya was Tripoli's Abu Salim prison.
Thousands were killed and tortured there amid gruesome conditions, although the exact number of victims will never be known because the secretive facility kept no records.
As Al Jazeera's Tony Birtley reports from Tripoli, one year after the first protests that culminated in the revolution, Abu Salim remains a powerful symbol of the worst brutalities of the Gaddafi regime.
In a recent interview with Al Jazeera, a Libyan who was on death row in the prison described his life there.
