“We advise you to exercise a high degree of caution in South Africa due to the high level of serious crime. You should pay close attention to your personal security at all times,” the commission said.
“There have been reports of race-related violence in the villages of Kwa Mushu and Umlazi in Kwa-Zulu Natal, and in the central business districts of Durban and Johannesburg.”
