Gaza has become a 'graveyard' for children with thousands now killed under Israeli bombardment, while more than a million face dire shortages of essentials and a lifetime of trauma ahead, UN humanitarians said on Tuesday.

UN relief chief Martin Griffiths, who has been visiting Israel and the Occupied Palestinian Territory, spoke to families in Gaza over the phone from east Jerusalem on Tuesday and said that what they have endured since the start of Israel's retaliation for Hamas' deadly 7 October attacks is 'beyond devastating'.
