UN relief coordinator says situation in Gaza "the worst ever"

Martin Griffiths, the UN humanitarian and relief coordinator, has described the current destruction and death in Gaza as the worst he has ever seen in his entire career.

Speaking in an interview with CNN, Griffiths said that Gaza was a "global crisis", and that he was terrified to see that "war has become the obsession of the day".

"No, I don't think I've seen anything like this before. It's complete and utter carnage," he said.
