Lebanon Accuses Israel of Spraying Toxic Herbicide Along Border, Citing Glyphosate Detection

Allegations of Chemical Spraying Emerge

Lebanese authorities have accused Israeli aircraft of spraying chemical agents, identified as a highly concentrated toxic herbicide, along the border with Lebanon. The incident, reported to have occurred around February 1, 2026, has triggered widespread alarm over potential environmental damage and harm to civilian populations in southern Lebanon.

Glyphosate Identified at High Concentrations

Laboratory analyses conducted by Lebanese ministries of agriculture and environment confirmed the substance as glyphosate, a potent herbicide. Test results indicated concentrations ranging between 20 and 30 times higher than accepted limits for standard agricultural use. The World Health Organization (WHO) classified glyphosate in 2015 as 'probably carcinogenic to humans.' Officials stated that the spraying targeted cultivated areas and open land vital for local communities' farming and food production.

The potential impacts of this spraying are extensive, including:

• Damage to vegetation and agricultural production
• Contamination of soil and groundwater
• Threats to soil fertility and ecological balance
• Risks to public health and the entire food chain
• Undermining the livelihoods of farmers

Euro-Med Human Rights Monitor stated that the findings showed the substances were 'not conventional pesticides but highly toxic chemical compounds with destructive effects that are difficult to contain,' leading to 'long-term contamination of soil and groundwater, damage to livestock, and the dismantling of environmental infrastructure.'

International Condemnation and Official Responses

Lebanese President Joseph Aoun strongly condemned the action, describing it as a 'violation of national sovereignty' and a 'serious environmental and health offense.' Lebanon's foreign ministry announced plans to file a formal complaint before the United Nations Security Council, compiling a comprehensive legal file documenting the violations.

The United Nations Interim Force in Lebanon (UNIFIL) confirmed that Israeli authorities had informed them about planned spraying near the border, advising personnel to take shelter. UNIFIL spokesperson Stephane Dujarric stated that the alleged use of herbicides 'raises questions about the effects on local agricultural lands and how this might impact the return of civilians to their homes and livelihoods in the long term.' UNIFIL called the activity 'unacceptable,' citing risks to the health of its personnel and nearby civilians, and potential environmental consequences, also noting that 'any activity by the IDF (Israeli Army) north of the Blue Line is a violation of resolution 1701.' The Israeli military has declined to comment on the allegations.

Broader Context of Environmental Concerns

This incident occurs against a backdrop of existing environmental damage in southern Lebanon from previous hostilities. Reports indicate that the region still bears 'ecological scars' from an intense campaign that ended just over a year ago, which included accusations of using white phosphorus and incendiary bombs that burned farmland and forests, leaving soils polluted. Similar chemical spraying incidents have also been reported in southern Syria.
