Alleged herbicide spraying
Lebanon has accused Israeli aircraft of spraying an agricultural herbicide across villages and farms in southern Lebanon.
“Lebanon has accused Israel of spraying a cancer-linked herbicide over farms in southern Lebanon, calling it an “environmental and health crime” that threatens food security and farmers’ livelihoods.”
Lebanese laboratory tests identified the chemical as glyphosate and found concentrations far above normal agricultural use.
Lebanese authorities and President Michel Aoun described the action as an "environmental and health crime" and a violation of sovereignty.
Officials reported samples contained glyphosate at about 20-30 times normally accepted levels.
The Israel Defense Forces declined to comment on the allegations.
Alleged aerial spraying incident
Lebanese officials say the spraying was carried out from light military aircraft and that video footage exists.
They say UNIFIL has also been involved in the matter, though accounts vary.
Lebanon's agriculture and environment ministries say their laboratory tests identified glyphosate and that concentrations were dramatically above normal application rates.
The Lebanese Foreign Ministry has begun documenting allegations and said it will coordinate with agriculture, environment and public-health ministries and scientific bodies to identify substances and assess damage.
Aerial glyphosate impacts
Lebanese politicians, environmentalists and health officials warned of acute and long-term harms from aerial glyphosate application.
“Lebanese MP Abdul Rahman Al‑Bizri, a member of parliament’s health committee, warned that aerial spraying of glyphosate ... poses serious health and food‑security risks.”
MP Abdul Rahman Al-Bizri and other officials flagged immediate symptoms such as skin rashes, eye irritation and respiratory complaints.
They also warned of chronic risks, which some studies link to lymphoma and blood disorders.
Environmental groups said repeated spraying would have cumulative, complex and deep impacts on soils, crops, pollinators and livelihoods.
The episode compounds already severe damage to farmland and ecosystems following the 2023-24 conflict, which the UN FAO estimated caused substantial agricultural losses.
Lebanon response to spraying
Lebanon says it will pursue legal and diplomatic measures, preparing documentation and a formal complaint to international bodies while stepping up a diplomatic offensive.
President Aoun publicly condemned the action.
Some reporting highlights open questions about the episode, noting that the stated purpose of any spraying has not been made public.
The IDF declined to comment.
There is scientific and regulatory debate over glyphosate's potential cancer risks, leaving uncertainties about intent, legal classification and long-term environmental effects.
