FW de Klerk tells Dublin audience: Donald Trump 'not doing the free world a favour' with his tweets

The last white leader of South Africa FW de Klerk has warned US President Donald Trump that he is not doing the free world any favours by sending overzealous tweets.

The former president, who freed Nelson Mandela and oversaw the end of apartheid in the 1990s, accused Mr Trump of overreacting on the North Korea missile testing crisis.
