Lawyers Targeting Arms Manufacturers Over Potential Complicity in Gaza War Crimes

By: Lina Irawan • Nov 13, 2026 • 4 min read

Prominent legal experts are expanding the scope of international investigations into the ongoing conflict in Gaza, warning that weapon manufacturers and corporate executives who supply arms to Israel could face criminal liability under international law.

According to lawyer Tayab Ali, corporate entities and company directors who provide military equipment and munitions, knowing there is a clear likelihood that those weapons will be used in the commission of war crimes, may be in direct violation of Article 25 of the International Criminal Court (ICC) statute. This legal perspective shifts part of the accountability framework away from battlefield operations alone and places it firmly onto the global supply chains that fuel modern military campaigns.

The scrutiny on arms suppliers comes amid mounting documentation of civilian infrastructure being targeted in Gaza, including schools, hospitals, and United Nations facilities. Human rights organizations and international observers have repeatedly raised alarms over the scale of destruction and the types of weaponry utilized during the bombardment.

Highlighting visual evidence gathered by Anadolu Agency, which appears to show the deployment of white phosphorus shells by the Israeli military, legal analysts emphasize the urgent need to trace the exact origins of these munitions. White phosphorus is a controversial substance that, while permitted under certain military contexts for illumination or smoke screens, is strictly regulated and prohibited for use as a weapon against civilian populations or in densely populated civilian areas under international humanitarian law.

In discussing the evidentiary requirements for establishing corporate accountability, Ali underscored the meticulous investigative steps necessary to build a viable legal case. Establishing liability requires tracing the entire lifecycle of the munitions used in attacks on protected sites.

Investigators are currently working to identify the specific sources of these weapons, the manufacturing plants where they were assembled, the corporate entities responsible for their production, the precise timeline of their delivery to Israel, and the individual company directors who were exercising managerial and operational control at the time the shipments were authorized and dispatched.

Under the framework of international criminal jurisprudence, individuals within corporate leadership who knowingly facilitate or contribute to international crimes through the provision of military hardware can face severe legal consequences. Article 25 of the Rome Statute outlines various forms of individual criminal responsibility, including aiding, abetting, or otherwise assisting in the commission or attempted commission of a crime within the jurisdiction of the ICC, which encompasses war crimes, crimes against humanity, and genocide.

This legal doctrine has historically been applied in various contexts of corporate complicity, where commercial entities supply materials or services to state actors engaged in systemic violations of international law. By scrutinizing the boardrooms of defense contractors and munitions manufacturers, legal advocates aim to establish a precedent that corporate immunity does not extend to the supply of lethal weaponry used in violation of the Geneva Conventions and customary international law.

The growing focus on the international arms trade has also resonated sharply at the grassroots level, where civil society groups, human rights activists, and labor unions have mobilized to disrupt the flow of military supplies. In the United Kingdom, these concerns manifested directly last month when activists and trade unionists coordinated protests and blockaded arms manufacturing facilities in multiple locations across the country.

The demonstrators voiced unified demands for an immediate and comprehensive arms embargo on Israel, arguing that domestic manufacturing plants and industrial suppliers should not be complicit in the humanitarian catastrophe unfolding in Gaza. These direct action campaigns reflect a broader public disquiet regarding the role of Western supply chains in foreign military engagements, adding political and social pressure to the ongoing legal efforts.

As investigations by international bodies and legal experts continue to develop, the focus on corporate actors is expected to intensify. The potential legal exposure for defense contractors highlights a critical intersection between corporate governance, international humanitarian law, and global accountability.

By examining the paper trails and supply chains that connect industrial manufacturing plants to active conflict zones, legal advocates are striving to ensure that accountability for alleged war crimes extends far beyond the immediate theater of operations, reaching the executives and corporations whose commercial decisions sustain military operations around the world.
