The use of humanitarian corridors in Syria and Ukraine resulted in successful humanitarian operations, but also in catastrophic failures. In different instances, humanitarian corridors served as a tool to uphold inter national humanitarian law, bolster humanitarian access, and as confidence-building measures for conflict resolution attempts. But in Syria and during the siege of Mariupol in spring 2022, they turned into a method of warfare, and the civilians into bargaining chips. This paper highlights the consistencies and contradic tions between the successes and failures attained through humanitarian corridors in Syria and Ukraine and the patterns and theories identified in relevant research, contributing to critical debates around war, violence, and conflict resolution.
