GENEVA: Disruptions in global supply chains brought on by the war in the Middle East are impacting the delivery of tens of thousands of tons of food aid, the United Nations warned Tuesday. The World Food Programme said deliveries of desperately-need food for aid operations around the world were facing long delays and increasing costs. “For us, it’s the most significant disruption of supply chains that we have seen since Covid and the beginning of the war in Ukraine,” Corinne Fleischer, WFP’s supply chain chief, told reporters in Geneva, speaking via video link from Rome.
