"It's a complicated issue," said a high-ranking officer in the IDF's Office of the Coordinator of Government Activities in the Territories. Talking on condition of anonymity, he told Al-Monitor, "We are working with UNRWA, which takes care of hundreds of thousands of refugees, feeds about half of the Palestinian population in Gaza and tends to the welfare and education of its children." He added that UNRWA has cooperated with Israel and coordinates all of its operations with the Coordinator of Government Activities in the Territories.
