A United Nations official has broken down live on air as he talked about a deadly attack on a school in Gaza. <br /> <br />Chris Gunness wept uncontrollably as he discussed the Israeli shelling during an interview with Al Jazeera Arabic on Wednesday. <br /> <br />Addressing the camera, Gunness says, "The rights of Palestinians even their children, are wholesale denied… and it's appalling". <br /> <br />The Relief and Works Agency spokesman then bites his lip and clears his throat as he attempts to compose himself. <br /> <br />The interviewer appears to thank him and Gunness manages to utter the words, "My pleasure" before placing his head in his hands and sobbing. <br /> <br />Someone rushes over to comfort him and the camera pans away, though Gunness can still be heard weeping.
