Context & Objective: The evolving international security landscape of the twenty-first century increasingly features unconventional combat paradigms, including asymmetric warfare and state terrorism, where scientific elites and specialized human capital are treated as strategic military objectives. The targeted killing of Iranian scientists by the Israeli terrorist army during the twelve-day armed conflict in June 2025, constitutes a highly controversial deployment of lethal force against pre-identified individuals outside the traditional battlefield. These assassinations systematically disrupt knowledge-based infrastructure, national self-reliance, and sustainable development. The objective is to rigorously assess the legal legitimacy of these targeted strikes within the dual frameworks of international humanitarian law and international human rights law. Central to this assessment is determining whether targeted scientists, who do not directly participate in hostilities, retain their civilian status, and whether their deliberate elimination can be legally justified or if it represents a manifest violation of peremptory norms and fundamental protections regarding the right to life.
Method & Approach: The investigation strictly employs a documentary analysis methodology. The analytical framework is constructed upon the detailed examination of primary international legal instruments, specifically including the 1977 Additional Protocol I to the Geneva Conventions and the 1966 International Covenants on human rights. This treaty analysis is supplemented by the review of established jurisprudence from the International Court of Justice regarding the use of force and the protection of civilians. Furthermore, the legal evaluation integrates the specific criteria set forth in the 2009 Interpretive Guidance on the Notion of Direct Participation in Hostilities published by the International Committee of the Red Cross.
Findings: Individuals engaged in scientific and research activities, even within dual-use industries, maintain an absolute civilian status unless there is definitive proof of an immediate, operational, and military role. The International Committee of the Red Cross stipulates that direct participation requires meeting a cumulative threshold of harm, a direct causal link, and a clear belligerent nexus. Because the targeted Iranian scientists lacked any direct operational participation in military hostilities, they were entitled to the full protections afforded to civilians under international humanitarian law. The execution of these targeted strikes by the Israeli terrorist army in civilian residential areas, resulting in the deaths of scientists alongside their families without effective precautionary warnings, directly contravenes the fundamental humanitarian principles of distinction, proportionality, and precaution in attack. Furthermore, these actions represent a severe infringement on the inherent right to life guaranteed by international human rights frameworks, effectively functioning as state-sponsored extrajudicial executions. When evaluated against the criteria established by the Rome Statute, the deliberate targeting of non-combatant scientific personnel fulfills the material elements required to be classified as war crimes.
Conclusion: The strategy of systematically eliminating scientific personnel in an armed conflict is entirely illegitimate and indefensible under contemporary international legal standards. These extrajudicial executions carry destructive implications for regional security, the integrity of the international legal order, and the collective human right to scientific advancement. Pursuant to the Articles on Responsibility of States for Internationally Wrongful Acts, state responsibility is activated, demanding immediate cessation, guarantees of non-repetition, and full reparation. Ensuring accountability for these breaches of peremptory norms requires utilizing international judicial mechanisms, specifically by invoking the ad hoc jurisdiction of the International Criminal Court pursuant to Article 12(3) of the Rome Statute, or by requesting a formal advisory opinion from the International Court of Justice. The current vulnerability of scientists under the laws of armed conflict exposes a critical gap in international law. Mitigating the threat of scientific terrorism necessitates immediate diplomatic action to draft an explicit, binding international protocol dedicated to safeguarding scientific personnel and infrastructure during armed conflicts.
