UN humanitarian chief Martin Griffiths, who has played a key role in pressing for aid to the Gaza Strip and led earlier efforts for Yemen, has announced he will step down due to ill health.
Griffiths, who has headed the UN Office for the Coordination of Humanitarian Affairs (OCHA) and served as the emergency relief coordinator for three years, said he has informed Secretary-General Antonio Guterres of his intention to step down in June.
