Experts Urge New Rules for White Phosphorus Use

Human Rights Watch and the International Human Rights Clinic at Harvard Law School have released a report documenting twenty-three verified incidents of white phosphorus munitions use in southern Lebanon between March and May 2026. The joint study urges the international community to address what it describes as significant loopholes in existing legal frameworks that currently fail to adequately protect civilians from the severe physical and psychological trauma caused by these incendiary weapons.

Bonnie Docherty, a senior arms advisor at HRW and a lecturer at the IHRC, emphasized the urgent need for a formal condemnation of ongoing usage. She argued that nations must move beyond current diplomatic stances to engage in substantive international talks. The core objective, according to the report, is to ensure that international law explicitly addresses the unacceptable human costs associated with the deployment of these specific chemical munitions in conflict zones.

Limitations of Existing Incendiary Weapon Laws

The analysis centers on Protocol III to the Convention on Certain Conventional Weapons, adopted in 1980. While this protocol prohibits the use of incendiary weapons dropped from the air in concentrations of civilians, legal experts point out that its narrow definitions create significant gaps. The specific focus on air-dropped munitions leaves other delivery methods insufficiently regulated, raising concerns that the current legal shield for civilians is porous and incomplete in modern conflict scenarios.

To bridge these gaps, the report advocates for a broader application of the Martens Clause. This provision in international humanitarian law asserts that civilians are protected by customary international law and the dictates of public conscience even in the absence of specific treaties. The authors argue that where existing weapons fail to meet these fundamental humanitarian standards, targeted legal protections must be developed to close the regulatory void.

Humanitarian Impact and Medical Burden

White phosphorus is a chemical compound that ignites instantly upon contact with oxygen, capable of burning for days or weeks over an area of 125 to 250 meters per projectile. Medical professionals describe the resulting injuries as among the most painful an individual can experience. These include deep burns reaching the bone, severe respiratory damage, and organ failure, all of which require extensive and costly long-term medical intervention.

The rehabilitation process for victims is characterized as one of the most complex and time-consuming endeavors in modern medicine. It necessitates significant supplies, multiple surgeries, and prolonged psychological support. The report notes that treating these injuries places a heavy socioeconomic burden on both the victims and the healthcare systems in the affected regions, violating the principles of humane treatment and respect for human dignity.

Diplomatic Pathway for Regulatory Reform

The use of these weapons by Israeli forces has been a subject of long-standing concern, with previous evidence documented by Amnesty International and HRW in both Lebanon and the Gaza Strip. Citing widespread descriptions of the effects as horrific and cruel, the experts insist that current protections are inadequate. They are calling for the issue to be placed on the agenda at the UN General Assembly’s disarmament meeting scheduled for October 2026.

According to GN geopolitics/rights (en-US), the momentum for change relies on a shared moral guideline among governments and non-governmental organizations. The report highlights a growing consensus that the lack of legal consequences for indiscriminate use against civilians is no longer tenable. The forward question now centers on whether member states will commit to negotiating new binding regulations or if the diplomatic process will remain stalled by existing geopolitical divides.
