In South Africa, police attacked protesting students with tear gas and stun grenades, as students at the University of the Witwatersrand in Johannesburg protested for a second day against a proposed 8 percent tuition hike for 2017. The students are demanding free education. Last year, massive student protests across South Africa forced the university to back down from plans to increase tuition for this academic year. On Tuesday, at least 30 students were arrested and several were injured by police. The protests have forced the university to close for the week. The University of Cape Town was also closed Wednesday amid fear of protests.
