Pretoria - A violent confrontation has broken out between police and protesting students at the Union Buildings in Pretoria on Friday.
Police have thrown a few stun grenades at the students, but these failed to disperse the crowd.
The students, meanwhile, have set tyres and portable toilets on fire and pulled down a fence.
Police used water cannon to douse the fires lit , a Reuters witness said.
Students at tertiary institutions across South Africa have been protesting against the proposed fee hikes for 2016.
