South African media say police used stun grenades and rubber bullets to disperse a group of university students protesting planned increases in tuition fees.

News channel eNCA posted video on its website showing police clearing a road that was blocked by students Wednesday at Nelson Mandela Metropolitan University in the South African city of Port Elizabeth.

Hundreds of students also demonstrated peacefully against planned tuition hikes outside parliament in Cape Town on Wednesday.

The protests are part of a wave of nationwide protests at South Africa universities, which say they are struggling with higher operational costs as well as inadequate state subsidies.

The University of the Witwatersrand in Johannesburg suspended activities for the rest of the week because of the demonstrations. The University of Cape Town was also closed Wednesday.
