Over 25 years ago, Souleymane Guengueng, a deeply religious civil servant who watched dozens of his cellmates succumb to torture and disease in Hissène Habré’s Chadian prisons, took an oath that if he ever got out of jail alive, he would bring his tormentors to justice.
Today I sat alongside Souleymane and other survivors as Habré was convicted of atrocities by a special court in Senegal, where he’s lived in luxurious exile since his overthrow in 1990.
