The South African government has criticised the US's decision to prioritise refugee applications from white Afrikaners, saying claims of a white genocide have been widely discredited and lack reliable evidence.

It highlighted an open letter published by prominent members of the Afrikaner community earlier this week rejecting the narrative, with some signatories calling the relocation scheme racist.

The limited number of white South African Afrikaners signing up to relocate to the US was indication that they were not being persecuted, it added.

On Thursday, the administration of US President Donald Trump announced its lowest refugee annual cap on record - to just 7,500.

The exact figures of the number of white South Africans who have been admitted through the US scheme are not available.
