What's happened
On March 3, 2026, Human Rights Watch verified Israel's use of white phosphorus artillery shells over the Lebanese town of Yohmor, causing fires in residential areas. Israel denies targeting civilians and claims limited use of white phosphorus for smoke screens. The attacks have displaced hundreds of thousands amid ongoing conflict with Hezbollah in southern Lebanon.
What's behind the headline?
Legal and Humanitarian Implications
The verified use of white phosphorus by Israel over residential areas in Yohmor constitutes a serious breach of international humanitarian law, specifically the prohibition against incendiary weapons in populated zones. Despite Israel's claims of using white phosphorus solely for smoke screens, the evidence of airburst munitions causing fires in homes and vehicles reveals a disregard for civilian safety.
Strategic and Political Dimensions
Israel's preemptive evacuation orders suggest an awareness of the risks posed by these munitions, yet the continued use indicates a strategic calculus prioritizing military objectives over civilian protection. This pattern, documented since 2023, reflects a broader conflict dynamic where civilian areas become battlegrounds, exacerbating displacement and humanitarian crises.
International Response and Accountability
Human Rights Watch's call for suspending military assistance to Israel places pressure on Western allies, notably the US, UK, and Germany, to reconsider arms sales. Lebanon's potential accession to the International Criminal Court could open avenues for legal accountability, though enforcement remains uncertain.
Forecast and Consequences
The ongoing use of white phosphorus will likely deepen regional instability, fuel anti-Israel sentiment, and complicate peace efforts. The humanitarian toll, including severe injuries and displacement, will persist unless international mechanisms enforce compliance with laws of war. Civilians in southern Lebanon face prolonged suffering, with environmental damage further undermining recovery prospects.
How we got here
Tensions between Israel and Hezbollah escalated after Hezbollah's March 2 attack, prompting Israeli strikes across southern Lebanon. White phosphorus, used legally for smoke screens, has been controversially deployed by Israel in Lebanon since 2023, with repeated accusations of unlawful use in populated areas causing civilian harm and environmental damage.
Our analysis
Human Rights Watch (HRW) has provided detailed verification of white phosphorus use in Yohmor, highlighting the incendiary effects and legal violations. Ramzi Kaiss, HRW's Lebanon researcher, described the use as "extremely alarming" with "dire consequences for civilians" (Al Jazeera, Reuters). Israel's military spokespersons have consistently denied targeting civilians, stating they "cannot confirm use of shells that contain white phosphorus" and emphasizing their policy against deploying such munitions in densely populated areas (France 24, The Independent). The New Arab's Richard Weir underscored the "continuous pattern of unlawful use" and urged allies to suspend military assistance. Lebanese authorities have reported hundreds of injuries linked to white phosphorus exposure and widespread displacement due to Israeli strikes. The contrasting narratives reveal a contested battlefield where humanitarian concerns clash with military justifications, underscoring the urgent need for independent investigations and international oversight.
