AFP PICTURES OF THE YEAR 2016 The flash of an exploding stunt grenade is seen while an University of Witwatersrand student jumps on a falling policeman while another policeman discharged his rubber bullet loaded rifle during a running battle with the police forces on campus during a mass demonstration on October 4, 2016 in Johannesburg. South African police fired rubber bullets, stun grenades and teargas at student protesters in Johannesburg as authorities tried to re-open the prestigious Wits University after weeks of demonstrations. The university, along with many campuses across South Africa, has been closed for at least two weeks during protests over tuition fees, with violent clashes regularly erupting between students, police and private security guards. / AFP PHOTO / MARCO LONGARI
