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 / MARCO LONGARI (Photo credit should read MARCO LONGARI/AFP/Getty Images)
