South African police patrolled central Johannesburg on Tuesday after the financial capital was hit by a new wave of anti-foreigner violence.
Rocks, bricks and rubber bullets strewed the empty streets of Alexandra after mobs plundered the township overnight, burning and looting the shops in their path.
AFP photographers in Alexandra said police presence remained heavy and that rubber bullets were still being fired to disperse the crowds. The police were scheduled to meet with community leaders later on Tuesday.
The township was scene to a second night of urban rioting in Johannesburg, where hundreds of people marched through the streets on Monday in an unusually large expression of anti-foreigner sentiment.
More than 90 people were arrested "after looting shops and damaging property in Johannesburg and surrounding areas", said a government statement released late on Monday.
Such violence breaks out sporadically in South Africa where many nationals blame immigrants for high unemployment, particularly in manual labour.
