South Africa’s delegation landed in crisis-hit Zimbabwe on Tuesday to mediate an end to a crackdown on conflict in the southern African country. Years of repression in Zimbabwe worsened in the run-up to banned anti-government protests on July 31st, during which at least 20 demonstrators were arrested and charged with inciting public violence. Zimbabwe President Emmerson Mnangagwa has since vowed to "flush out" the "bad apples" attempting to "divide our people" -- stoking concern among social activists and opposition figures already targeted by the regime.
