In March , violence broke out between supporters of the ANC and of Inkatha in kwaZulu ; Tutu cancelled a visit to the US to join the SACC delegation in talks within Mandela , de Klerk , and Inkatha leader Mangosuthu Buthelezi in Ulundi . Church leaders urged Mandela and Buthelezi to hold a joint rally to quell the violent rivalry between their respective parties . Although Tutu 's relationship with Buthelezi had always been strained — particularly due to Tutu 's opposition to Buthelezi 's collaboration in the apartheid government 's Bantustan system — the clergyman visited Buthelezi on a number of occasions to encourage his involvement in the democratic process . As the ANC-Inkatha violence spread from kwaZulu into the Transvaal , Tutu toured affected townships in Witwatersrand , visiting those made homeless and calling for peace . He visited the victims of the massacre at Sebokeng , and later those of the Boipatong massacre
