Introduction. Humanitarian crises in the conflicts of recent decades directly affect the security of not only neighbouring states, but also undermine the established system of humanitarian cooperation between states. Non-state actors: terrorist organizations, separatist groups, protest movements, paramilitary religious groups and others that participate in conflicts and choose violent measures, complicate the resolution of conflicts. Despite the fact that all parties to the conflict are obliged to comply with the norms of international humanitarian law, both states and non-state actors are increasingly moving away from the principles of humane treatment of the civilian population. Each of the parties puts forward its own justifications for the indiscriminate approach. Materials and methods. The study is based on the case study method. An analysis of the changes in the provision of humanitarian aid to the civilian population during the humanitarian crisis in the Gaza Strip makes it possible to draw conclusions about the current trends in the development of the humanitarian sphere as a whole. The author used materials from Russian and foreign media, UN and INGO reports, and international treaties. Reseach results. The conflict complicated the peace process, normalization of relations between Israel and Arab states, and also exposed the problem of politicization of humanitarian aid. Politicization manifested itself not only in the assessment of the conflict itself, which has long divided the world community, but first of all, for the first time, it had such a large-scale impact on the UN humanitarian aid institutions and various INGOs. The politicization of theconflict also resulted in the manifestation of a "cancel culture", which stigmatized the parties to the conflict and complicated the activities of humanitarian organizations in providing assistance to the civilian population. Discussion and conclusion. However, the most serious consequences are not only in the area of worsening the humanitarian situation, threats to civilians and employees of intergovernmental and non-governmental organizations involved in providing humanitarian aid to the affected population, collecting information on the situation of civilians, the balance of power and compliance with international humanitarian law, but also in the area of compliance with the principles of humanitarian aid themselves. The humanitarian community is divided between those who support Israel's position and its stated "right to self-defense" and those who advocate for its accountability along with Hamas for what the UN Secretary General called "excessive use of force". An analysis of the impact of humanitarian crisis in the Gaza Strip on the process of conflict resolution is of great scientific interest, and its results can enrich knowledge not only about the peace process itself, but also about the role of humanitarian sphere in world politics.
