This is WEEKEND EDITION from NPR News. I'm Linda Wertheimer. Scott Simon is away. Mobs with machetes attacked immigrants in Durban, South Africa on Thursday, forcing thousands to seek shelter. The government is now caring for some 1,500 migrants in a camp in the nearby suburb of Chatsworth. The BBC's Milton Nkosi has just returned from the area. He joins us now from Johannesburg.
WERTHEIMER: Can you tell me what started this, what brought on these attacks?
