by Gao Yuan CAPE TOWN Cheap Jordan 1 , Feb. 26 (Xinhua) -- Violent protests at some universities in South Africa saw no sign of abating on Friday despite growing calls for academic programs to return to normal.

Students at the university have been protesting against using Africaans as a medium of instruction. At least 27 people were arrested last week for suspected involvement in acts of violence. Protest at the university spilled out of campus when protesters torched a Metrorail train and attacked rail workers. ""We will employ an approach of zero tolerance.

""Earlier today, the management of the University of the UFS reached an agreement with contract workers about negotiations towards outsourcing, as well as their concerns about conditions of employment with their employers,"" the statement said.
