Johannesburg - Seven Zimbabweans, four men and three women, were found dead in South Africa after their shack in Western Cape province was allegedly set alight, police said Monday.

A police spokesman told SAfm public radio that the alleged attack, which took place in a squatter camp, was under investigation.

Last year, mobs killed at least 62 people and drove thousands of others from their homes in a two-week frenzy of xenophobic violence targeting mostly migrants from neighbouring countries, such as Zimbabwe, Mozambique and Malawi.

The mobs blamed the millions of African migrants in South Africa for providing unwelcome competition for scarce jobs and public housing. (dpa)
