Parsing the UN Fact-Finding Mission’s Report on U.S. Strikes in Iran

The UN Independent International Fact-Finding Mission on the Islamic Republic of Iran issued its report on Sept. 17 concluding that U.S. air operations on Feb. 28, the first day of joint U.S.-Israeli hostilities against Iran, resulted in war crimes under international humanitarian law (IHL). The report, which also convincingly establishes the Iranian government’s crimes against humanity against its own population, concludes that the U.S. Tomahawk missile strike on the Shajareh Tayyebeh Primary School in Minab was an indiscriminate attack resulting from a reckless failure of target verification. The UN mission also finds that a second, less reported strike on the first day of the war, a Precision Strike Missile (PrSM) attack on the Lamerd Sports Complex, constituted a disproportionate attack due to the selection of a wide-area kinetic fragmentation weapon in a populated area.

The UN report, however, provides little legal analysis of why the fact-finding mission concluded that these attacks are war crimes. This article provides a deeper analysis of the law relevant to the UN report’s conclusions.

The Minab Bombing: Reckless Precautionary Failures as an Indiscriminate War Crime

The killing of 178 people, mostly children, at the Minab primary school underscores how systematic breakdowns in target verification, including possible insufficiently vetted reliance on artificial intelligence (AI), can lead to war crimes. According to the UN report, U.S. forces had executed the strike using outdated intelligence databases that listed the facility as a naval installation belonging to the Islamic Revolutionary Guard Corps (IRGC). Crucially, targeting authorities failed to conduct feasible prestrike verification or cross-reference readily available, open-source records showing that the location had ceased military operations years ago and was transformed into an active elementary school no later than 2015.

AP I Article 51(4)(a) and the Concept of Indiscriminateness

Under Article 51(4)(a) of the Additional Protocol I to the Geneva Conventions (AP I), indiscriminate attacks are prohibited and defined as those “which are not directed at a specific military objective.” While the principle of distinction obligates belligerents to distinguish between military objectives and civilian objects at all times, the rule of precaution codified in Article 57(2)(a)(i) of AP I requires those who plan or decide to carry out an attack to “do everything feasible to verify that the objectives to be attacked are neither civilians nor civilian objects.”

Although the United States is not a party to AP I, the U.S. acknowledges that the rules of distinction and precaution constitute binding customary international law and endorses these principles in its own military manuals. When targeting planners proceed with a strike on stale, unverified intelligence without taking basic, accessible precautionary steps to confirm current usage, the failure is not just negligence. Instead, it becomes a more culpable case of reckless disregard. (Reckless conduct is more culpable than mere negligent conduct because it entails intent: the knowing disregard of a risk, as distinct from the mere lack of awareness of risk. This distinction applies in both U.S. law and in international law.)

Launching a weapon with conscious indifference to whether the target is military or civilian strips the strike of its discriminate character; an unverified target is legally equivalent to an unspecified target, rendering the attack inherently indiscriminate under Article 51(4)(a). To be clear, no one alleges that the U.S. military deliberately struck a children’s school. Rather, it is alleged that conscious decisions bypassed established vetting requirements that would have disclosed the civilian nature of the target.

Customary Criminalization and Rome Statute Article 8

Under the Rome Statute of the International Criminal Court Article 8(2)(b)(i), it is a war crime to “intentionally direct attacks against the civilian population as such or against individual civilians.” While the Rome Statute does not explicitly use the term “indiscriminate,” customary international law treats indiscriminate attacks executed with reckless disregard (dolus eventualis) as equivalent to intentional direct attacks on civilians.

When an attacker acts with reckless indifference to the outcome, knowing that an unverified target may well be civilian, the legal requirement of intent is satisfied. Although neither the United States nor Iran is a party to the Rome Statute, the criminality of these omissions is generally acknowledged as a matter of customary international law.

ICTY Jurisprudence

The legal bridge between “indiscriminate” and “intentional” is grounded in jurisprudence of the International Criminal Tribunal for the former Yugoslavia (ICTY). In Prosecutor v. Galić, the tribunal established that attacks conducted indiscriminately, or with reckless disregard for civilian presence, qualify as direct attacks against civilians—that reckless disregard satisfies the requisite mental state.

Relevance of the U.S. War Crimes Act

The Minab strike may also constitute a war crime under the U.S. War Crimes Act (18 U.S.C. § 2441), which incorporates the regulations annexed to the 1907 Hague Convention IV, making violations of its provisions federal crimes punishable under U.S. law. Specifically, the War Crimes Act incorporates Article 25 of Hague IV, which provides that “the attack or bombardment, by whatever means, of towns, villages, dwellings, or buildings which are undefended is prohibited.” Striking an active elementary school—an undefended civilian structure devoid of military defense or active military function—directly triggers this statutory prohibition.

The War Crimes Act also incorporates Article 27 of Hague IV, which commands that “in sieges and bombardments all necessary steps must be taken to spare, as far as possible, buildings dedicated to religion, art, science, or charitable purposes, historic monuments, hospitals, and places where the sick and wounded are collected, provided they are not being used at the time for military purposes.” Educational facilities such as the Minab primary school fall squarely within the protection extended to buildings dedicated to science and religion. Because U.S. officials acted with reckless disregard and failed to take “all necessary steps” to verify current usage despite accessible open-source evidence showing the facility was not being used for military purposes, the strike arguably violates the statutory protections incorporated under § 2441.

The Lamerd Sports Complex: Weaponry, Disproportionality, and Criminality

The attack on the Lamerd Sports Complex, also conducted on the first day of hostilities, was a separate legal failure centered on weapon selection and collateral impact. U.S. forces targeted the facility using a Precision Strike Missile fitted with an alternative warhead.

To avoid the unexploded ordnance hazards associated with traditional cluster munitions banned under the Convention on Cluster Munitions, the PrSM alternative warhead utilizes a unitary airburst casing. When detonated above the target, it releases approximately 180,000 preformed inert tungsten fragments. The kinetic blast pattern covers about 90,000 square meters, equivalent to about 18 American football fields.

Under Article 51(5)(b) of AP I, a disproportionate attack is categorized as a form of indiscriminate attack. AP I defines it as a strike “which may be expected to cause incidental loss of civilian life, injury to civilians, damage to civilian objects ... which would be excessive in relation to the concrete and direct military advantage anticipated.”

The legal metric for proportionality requires balancing two distinct variables: anticipated military advantage (the concrete, direct military gain expected from neutralizing the target) against expected incidental civilian harm (the foreseeable civilian death, injury, and structural devastation resulting from the attack). When targeting planners deploy an area-effect fragmentation munition within an urban center, showering 180,000 tungsten pellets over an area equivalent to 18 football fields, the expected civilian casualties among stadium personnel, athletes, and nearby residents are likely to eclipse any localized military advantage.

The criminal status of disproportionate strikes is codified in Rome Statute Article 8(2)(b)(iv), which defines a war crime as the act of “intentionally launching an attack in the knowledge that such attack will cause incidental loss of civilian life or injury to civilians ... which would be clearly excessive in relation to the concrete and direct overall military advantage anticipated.”

ICTY jurisprudence establishes when disproportionality crosses into criminal conduct. In Prosecutor v. Dragomir Milošević, the tribunal held that deploying inherently wide-area impact weapons in urban areas violates the principles of distinction and proportionality. When a weapon’s blast or fragmentation envelope cannot be contained within the immediate perimeter of a military asset located in a residential area, the resulting civilian harm is foreseeable, and the strike is criminally disproportionate.

Day One Hostilities, AI “Target Acquisition,” and the Degradation of Oversight

Both the Minab and Lamerd strikes occurred on the first day of U.S. military operations against Iran. In the opening hours of a major air campaign, extreme operational velocity, mass target generation, and reliance on automated command-and-control architectures are common.

In modern operations, AI algorithms—that synthesize vast streams of satellite imagery, signals intelligence, radar returns, and historical data to generate real-time target packages—have increasingly driven target acquisition. This automation introduces a critical vulnerability, pitting algorithmic velocity against human capacity. AI platforms generate target lists at rates that outpace human analytical capacity.

The “Human in the Loop” Fallacy

While doctrine maintains that a human commander remains “in the loop” to approve strikes, operators face severe cognitive overload. Vetting dozens of complex targeting prospects every hour risks reducing human oversight to a formal rubber-stamping exercise, leaving no time to challenge algorithmic recommendations, cross-reference open-source data, or audit whether a facility’s intelligence profile is stale—as occurred in Minab.

Systemic Policy Shifts: “Lethality Over Legality”

A shift within the U.S. defense establishment against civilian harm protections exacerbated these operational failures. Facing high-tempo, multi-front conflicts, command structures prioritized operational velocity and, if Defense Secretary Pete Hegseth’s admonitions are taken at face value, elevated “maximum lethality over tepid legality” and eschewed “stupid rules of engagement.”

This policy environment led to the marginalization of judge advocate generals (JAGs), the operational legal officers who were systematically sidelined or removed from immediate strike clearance workflows. Rejection of such allegedly “woke” procedures designed to mitigate civilian harm, and erosion of precautionary standards by lowering the threshold for target clearance, arguably contributed to reliance on unverified legacy databases in Minab and the approval of wide-area kinetic fragmentation munitions in the populated Lamerd Sports Complex attack.

Regression in the International Regulation of Autonomous Weapons

The operational realities exposed in Minab and Lamerd intersect with recent developments in international disarmament diplomacy regarding lethal autonomous weapons systems (LAWS). States have spent years debating standards for the human role within the UN Group of Governmental Experts (GGE) on Emerging Technologies in the Area of LAWS under the Convention on Certain Conventional Weapons.

A key point of contention in the GGE has been the standard of “meaningful human control.” However, recent consensus outcomes within the UN framework are troubling: Negotiators diluted the requirement of “meaningful human control” down to the far weaker formulation of “human control.” This textual shift is a significant step backward for international humanitarian law. “Human control” requires nothing more than a human presence in the kill chain—a mechanical button-press.

“Meaningful human control,” by contrast, requires that the human operator has the situational awareness, time, contextual understanding, and practical ability to assess the lawfulness of a strike under applicable IHL principles of distinction, precaution, proportionality, and military necessity. Day one of the hostilities in Iran demonstrated that mere “human control” is insufficient to prevent catastrophic IHL violations when operators are inundated with automated data and stripped of robust legal review. Reducing the international standard to nominal human control validates automated target acquisition models that reduce human operators to legal ciphers—severing the link between human judgment and accountability in modern warfare.

Strategic and Political Disadvantages for the United States

The institutional choice to prioritize lethality over legal compliance and dismiss “stupid rules of engagement” undermines U.S. national security and political interests. Unlawful strikes that international investigative bodies designate as war crimes erode cohesion and alienate key allies whose participation in operations is therefore prohibited by the Geneva Conventions. Operations that breach international law also expose U.S. military personnel and commanders to foreign criminal investigations under universal jurisdiction doctrines.

High-visibility civilian casualties, particularly involving children in schools, undermine strategic messaging regarding democratic values, alienate nonaligned partner nations, and provide adversaries with powerful propaganda tools. The United States appears not to have learned the lessons of the “global war on terror” that U.S. abuses played into the hands of al-Qaeda and other terrorist groups to use as a recruiting tool.

The UN fact-finding mission report credibly argues that these attacks not only are violations under IHL but also constitute war crimes. Had the report been more detailed in its analysis, it might have provided a more forceful rejoinder to some states’ efforts to weaken legal standards and practices that guard against civilian harm in war.
