Twitter CEO Elon Musk has accused black South Africans who sing "Kill the Boer" of inciting the "genocide of white people".

But last year a court threw out a similar hate-speech claim made by a right-wing pressure group.

"There is no causal link between the chants and actual violence being committed on anyone," Economic Freedom Fighters (EFF) party spokesman Sinawo Tambo told BBC Newsday.

EFF leader Julius Malema led thousands of party faithful singing "Kill the Boer, Kill the farmer" at their 10-year anniversary rally at the weekend.

Footage of the left-wing, majority black audience chanting was posted on Twitter soon after, prompting Mr Musk's reply that this was a call to white genocide and that South Africa's president must act. Mr Musk was born in South Africa but moved to Canada aged 18.

Mr Tambo says his comments are nonsense:

"It's a symbolic song that's part and parcel of the history of South Africa's liberation struggle, and its colonial and apartheid domination.

"We chant it to reignite the passion and flame, to chant against white supremacy as a system... To point out that the system of white supremacy that was presided over by predominantly white Afrikaner males - or Boers - must be destroyed.

"Our people are not irrational beings who will mistake a chant as an instruction to commit murder. There's an undermining of the intelligence of the African people - that they would mistake a song as an instruction to do something.

"It's been two or three days now since the rally - there's been no death in South Africa, even though there were hundreds of thousands of people chanting that song.

"There hasn't been any genocide, there hasn't been any death of a white person as a result of that chant. We must be able to logical about it."

Some white nationalists in the US have claimed that there there is a plot to wipe out white people in South Africa.

They say that white farmers are being increasingly targeted in murders.

Yet there is no evidence to suggest that such murders are on the rise.
