 Several trucks were set on fire at a main highway in South Africa on Friday night, closing one of the country's biggest roads whilst violent protests raged over the jailing of former President Jacob Zuma. Police on Saturday said they had arrested 28 people. Demonstrations erupted this week in part of Quasuno, Natal, KCN, Kuzuma's home province after the ex-leader handed himself over to the police to serve a 15-month jail term for contempt of court. On Friday, the High Court dismissed Zuma's application to have his arrest overturned in a case that has been seen as a test of the post-apatized nation's rule of law.
