A Unicef official in Palestine: “There are a million children in Gaza traumatized by the war” “Since the start of the war, more than 150 employees of UNRWA (the UN agency for Palestinian refugees) have perished in Israeli attacks,” he says. “The hygienic conditions in Rafah are terrible, there is only one latrine for every 500 or 700 people, which leads to the spread of diseases such as chronic diarrhea,’ he adds.
