 The protest started by supporters of South Africa's former president Jacob Zuma is spreading across cities. It has reached Gauteng overnight from KwaZulu Natal and police are now warning protesters to avoid Johannesburg's inner city. On Friday, several trucks were set on fire on a main highway, closing one of the country's biggest roads as the protests raged. On Saturday, police reported the arrest of 28 people and today, the protest has reached Johannesburg. The protests erupted after Zuma handed himself over to police to serve a 15-month jail term for contempt of court. He had earlier lost an appeal to have his arrest overturned.
