In response to the two mass killings of May 3rd and 4th, 2023, in Serbia, we aim to present a comprehensive overview of the challenges and innovations in integrating Eye Movement Desensitization and Reprocessing (EMDR) into crisis support interventions. This article explores the unique circumstances encountered during these interventions, offering insights into how EMDR was adapted to meet the specific needs of survivors, families, and communities deeply affected by these tragic events. Our presented experience may guide future crisis interventions in applying trauma-informed care, flexibility, and interdisciplinary collaboration to build more resilient and responsive systems of crisis support.
