Senegal prepared Monday to begin the trial of former Chadian dictator Hissene Habre, 25 years after he fled there following an eight-year, blood-soaked reign of terror at home. Once dubbed "Africa's Pinochet," the 72-year-old has been in custody in Senegal since his arrest in June 2013 at the home he shared in an affluent suburb of Dakar with his wife and children. Rights groups say 40,000 Chadians were killed between 1982 and 1990 under a regime propped up by fierce crackdowns on opponents.
