Abstract
The article is devoted to a comprehensive legal analysis of the participation of citizens of the Republic of Kazakhstan in foreign armed conflicts through the prism of international and national law. The relevance of the topic is due to the growing number of such cases, including participation in terrorist and mercenary groups, which poses a threat to both national and international security. The study examines key international legal acts, as well as the criminal legislation of the Republic of Kazakhstan, in particular the norms providing for responsibility for participation in armed conflicts abroad. Based on the results of the study, the directions of improving national legislation, strengthening international cooperation, as well as the introduction of preventive legal and institutional mechanisms aimed at preventing the involvement of citizens of Kazakhstan in illegal armed groups abroad are proposed.
