ADDIS ABABA (AFP) - South Sudan became the 54th member of the African Union (AU) after it received a majority vote from member states, including one from Sudan, the Pan-African bloc said Thursday. "The Commission has received the requisite number of written communications supporting the admission of South Sudan to the African Union as the 54th union member state," the AU said in a statement. Membership was granted after South Sudan submitted an official request to join the AU and became the first nation to be admitted to the body since 1993 when Eritrea was inducted.
