A Sudanese court sentenced 27 members of the national intelligence service to death by hanging on Monday over the killing of a teacher in detention in February during protests that led to the overthrow of former president Omar al-Bashir. It was the first time courts have handed down convictions over crackdowns on demonstrations in the months before and after Bashir was toppled in April. The death of teacher Ahmed al-Khair in the eastern town of Khashm al-Qirba became a rallying point during 16 weeks of protests against Bashir’s rule.
