In Part 2 of our interview with Sally Hayden, author of the new book, “My Fourth Time, We Drowned: Seeking Refuge on the World’s Deadliest Migration Route,” she discusses the conditions in Libyan refugee prisons and the role of the European Union and the United Nations in the humanitarian crisis. Hayden also describes how the Ukraine war has led to fuel and food shortages in many African countries. Hayden is the Africa correspondent for The Irish Times.
