The African Union has suspended Sudan’s membership, after soldiers with the ruling Transitional Military Council opened fire on sit-in protesters on Monday, killing at least 108 people and wounding more than 500 others. In a statement, the AU said Sudan would remain suspended until a civilian-led transitional authority is established. Sudan’s military took power in April after a month-long popular uprising led to the overthrow of longtime authoritarian President Omar al-Bashir.
