South African police are reported to have fired rubber bullets and tear gas on Thursday to disperse a crowd of anti-immigrant protesters in an eastern suburb of Johannesburg
About 200 protesters, shouting that they wanted immigrants to leave, had pelted passing vehicles and police with rocks on Thursday, triggering the show of force.
At least four people have been killed in a wave of anti-immigrant violence that started two weeks ago in Durban.
Johannesburg was the center of xenophobic attacks in 2008 that killed more than 60 people.
South Africa has erected safe camps in the coastal city of Durban for fleeing immigrants whose shops were looted and burnt.
South Africa, with a population of about 50 million, is home to an estimated 5 million immigrants, and its high jobless rate, widespread poverty and glaring income disparities make it a ripe candidate for outbreaks of anti-immigrant violence.
