The head of the World Health Organization

The head of the World Health Organization said Saturday he was "rethinking the approach" as outrage widened over his decision to name Zimbabwe’s President Robert Mugabe a goodwill ambassador.

"I’m listening. I hear your concerns. Rethinking the approach in light of WHO values. I will issue a statement as soon as possible", the director general of the UN health agency, Tedros Adhanom Ghebreyesus, said on Twitter
