On 12 May, 59 Afrikaners arrived in Washington to receive “refugee” status. At a press conference, President Trump said he had acted because Afrikaners - the white minority community that ruled South Africa during apartheid - face an existential threat. His words echoed the views of his South African born former adviser, Elon Musk, who has repeatedly used his X platform to amplify false claims of a “white genocide”. Many South Africans, including several Afrikaners that we have spoken to, dismiss the idea that they are under attack as wild misinformation.

This episode of The Documentary, comes to you from BBC Trending in-depth reporting on the world of social media.
