Israel's use of white phosphorus in Lebanon raises humanitarian concerns

White phosphorus is an incendiary compound that ignites when exposed to oxygen, producing intense heat, thick white smoke, and toxic fumes. The substance can reach temperatures exceeding 800 degrees Celsius and continues to burn for extended periods, creating hazardous conditions for civilians in affected areas.

The chemical's use in populated regions has become increasingly controversial under international humanitarian law. When deployed in civilian areas, white phosphorus can cause severe burns to skin and lungs, and its smoke contains phosphoric acid particles that pose respiratory hazards. The substance's self-igniting properties mean it can reignite if bandages are removed from wounds, complicating medical treatment.

Israeli military operations in Lebanon have incorporated white phosphorus primarily for creating smoke screens and illumination purposes, according to available reports. However, its deployment has drawn criticism from human rights groups and humanitarian organizations, which contend that use in or near civilian concentrations violates international conventions on weapons restrictions.

International humanitarian law permits white phosphorus for screening and illumination in military operations, but restricts its use in areas with civilian populations. The ongoing debate centers on the practical distinction between legitimate military application and potential civilian harm when the substance is deployed in proximity to populated zones.
