The murder of South African white supremacist Eugene Terreblanche is "a declaration of war" by blacks against whites, white supremacist Andre Visagie said Sunday

Terreblanche, killed by two black men Saturday in what police say was a wage dispute, led the Afrikaner Weerstandsbeweging movement, which aimed to create three all-white republics in South Africa.

But others, including Andre Nienaber — an Afrikaner Weerstandsbeweging member and relative of Terreblanche — and President Jacob Zuma were calling for calm. The police asked citizens not to politicize the murder.

Nienaber blamed the killing on young militant Julius Malema, who leads the African National Congress Youth League.

Malema led college students in singing a banned song which includes the lyrics "shoot the Boer," the Afrikaans word for white farmers descended from the early Dutch settlers.

A court has ruled that the lyrics are unconstitutional and are hate speech. The ANC has said it will challenge that ruling in a higher court.

The ANC insists the song is a valuable part of its cultural heritage and that the lyrics — which also refer to the farmers as thieves and rapists — are not intended literally and are therefore not hate speech.

Followers of Terreblanche gathered Sunday near his farm in Ventersdorp, 140 kilometres west of South Africa's commercial capital, Johannesburg.
