U.S. President Donald Trump has followed through on his promise to punish South Africa by signing an executive order stopping all aid and assistance to the country over what he called a human rights violation against a white minority group.

President Donald Trump signed an executive order to cut U.S. financial assistance to South Africa, the White House said on Friday, citing disapproval of its land policy and of its genocide case at the International Court of Justice against Washington's ally Israel.

South Africa is responding to an executive order signed by U.S. President Donald Trump, saying the move to freeze American aid "lacks factual accuracy."
