Hundreds of refugees outside United Nations High Commissioner for Refugees offices in Cape Town and Pretoria say their sit-in protests will continue until they are moved to other countries to escape xenophobic attacks in South Africa.
Their leaders have spoken to the UNHCR head Fellipe Grande who was on an official visit to South Africa this week.
He has urged them to continue their protest peacefully.
Grande commended South Africa, which was supported by fellow-Africans during the struggle against apartheid, for offering shelter to refugees now that there has been a transformation to democracy.
The refugees, mostly from the Democratic Republic of Congo, say their sit-in is drawing more support daily.
They are being given food and blankets by local residents.
Spokesman for the organisation Women and Children in Crisis Alex Nkoy says police are protecting them.
“The police are here and they have not made any arrests. Everyone is safe and we are grateful for this. I believe they are acting this way because we are meeting their demand to get of their country,” he said
He says the refugees fear the xenophobia in South Africa could develop into a genocide like in Rwanda.
