The United Nations humanitarian chief, Martin Griffiths, has described the earthquakes that have taken thousands of lives and caused huge devastation in southern Turkey and north-western Syria, as "the worst natural disaster" he has ever seen. He has been visiting some of the badly hit areas in Turkey. But, speaking to the ³ÉÈË¿ìÊÖ's chief international correspondent, Lyse Doucet, he also says that with more than 100 countries sending help, the international response has been "extraordinary".
