By its very nature, urban warfare involves the presence of civilians. And when cities become battlefields, it may be necessary to evacuate noncombatants from them—either due to humanitarian imperatives or because military objectives require it. But an array of legal obligations and other considerations arise when civilians are evacuated. And because discussions of evacuations are closely linked to those surrounding the conduct of siege warfare, this raises further questions of the legal issues related to sieges and the obligations of parties on both sides of siege warfare. To explore these questions, John Spencer is joined on this episode by Laurie Blank, a clinical professor of law at Emory University School of Law, director of the International Humanitarian Law Clinic, and author of the book International Conflict and Security Law.
