October 4, 2016 - Police fired stun grenades, rubber bullets and tear gas at hundreds of students who marched through the university's campus in Johannesburg, dancing the "toyi-toyi" - a common display of protest throughout decades of struggle against white rule.Demonstrations over the cost of university education, which is prohibitive for many black students, have highlighted frustration at enduring inequalities more than two decades after the end of apartheid.Protests first erupted last year, then eased off as the government froze fee increases and set up a commission to look into the education funding system. The unrest boiled over again, closing some classes and universities, when the commission said on Sept. 19 that fees would continue to rise, albeit with an 8-percent cap in 2017.
