Cinemas in South Africa will not be showing the documentary about US First Lady Melania Trump that is due to be released around the world on Friday.

The South African distributor Filmfinity has decided not to release it, its head of sales and marketing told the New York Times and South Africa-based website News24. The company was not explicit about the reasons behind the move.

The film, Melania, is not promoted on the websites of the country's main cinema chains. One Cape Town independent cinema contacted by the BBC said that it was called by Filmfinity and told not to list it.

Relations between the US and South Africa have seriously deteriorated over the past year.

Amazon has reportedly paid $35 million (£25 million) to market the film, which follows Melania Trump in the 20 days leading up to her husband's second inauguration on January 20 last year.

Filmfinity's Thobashan Govindarajulu was quoted as saying that the decision was made given the current climate, although he didn't elaborate on what he meant by recent developments or current climate. Attempts to get a comment from Filmfinity have been unsuccessful.

Since Donald Trump came to power, US relations with South Africa have slumped due to various contentious issues, including allegations of white genocide against South Africans and the imposition of tariffs on South African goods.
