The State Department says South Africa’s ambassador to the United States has until Friday to leave the country.

Ties between the United States and South Africa have deteriorated since Trump cut U.S. financial aid to the country.

Soon after it was announced at the weekend that he was going to be expelled from the US, Ambassador Rasool wrote that he and his family were "all packed up and looking forward to returning to South Africa" and said he was leaving the US with "no regrets".
