Al Jazeera's Kalay Maistry reports on the attacks in South Africa on foreign workers.
Most of those targeted by the attacks are Zimbabweans and Somalis.
Maistry has spoken to a Somali victim of the violence in the north west province.
South African soldiers have shot and killed a man in a slum east of Johannesburg.
It happened as police were trying to suppress township violence that has targeted migrants in South Africa.
Meanwhile, several hundred people joined a march in protest at the attacks in Johannesburg.
At least 42 people have died, and thousands have fled their homes.
