On the morning of May 3rd 2023, a school shooting occurred at Vladislav Ribnikar Model Elementary School in the Vračar municipality of Belgrade, Serbia. The shooter, identified as 13-year-old Kosta Kecmanović, opened fire on students and staff, resulting in the deaths of ten individuals, including nine students and a security guard. Six others, five students and a teacher, also sustained injuries.
Kecmanović surrendered willingly and was taken into custody. However, due to his age being below 14, which falls below Serbia's age of criminal responsibility, he could not face legal charges. His father legally owned the firearms used in the incident. Since the apprehension, Kecmanović has been placed under the care of a psychiatric hospital located in Belgrade.
