The South African police say that with the Operation Dudula Movement gaining momentum in Gauteng, there are signs it is also spreading to KwaZulu-Natal and, to a lesser extent, Limpopo and Mpumalanga, warning that this is likely to heighten xenophobic tensions and cause instability with South Africa’s neighbours in the Southern African Development Community. “An issue of concern is that [Dudula] members are perceived by their supporters to be fulfilling the functions of state departments and local municipalities in terms of addressing the issue of illegal foreign nationals. This sets a dangerous precedent and heightens the risk of vigilante activity against foreign nationals,” News24 quotes a police presentation as saying.
