Escalating conflicts across the Middle East are driving mass displacement and straining already fragile humanitarian systems. What happens when millions are forced from their homes faster than aid can reach them? And how can global institutions respond when crises spread across borders and resources fall short? In this edition of The Hub, Wang Guan speaks with Karolina Lindholm Billing, representative of the UN Refugee Agency in Lebanon, and Salvador Gutierrez, representative of the International Organization for Migration in Iran, to explore the growing scale of displacement across Iran, Lebanon, and the wider region, and examine how humanitarian agencies are adapting to meet urgent needs amid ongoing conflict.
