The Israelis used it against the Lebanese in 2006.
The Israelis used it against the Palestinians in Gaza in 2006 also.
And the Israelis are using it again against the Palestinians in Gaza now.
(And before them, the US military used it in its wars from Vietnam to Iraq.)
From that article:
What is it: “White Phosphorus (P4) is a waxy fat soluble colorless or slightly yellow solid with a garlic smell that is not naturally occurring but is produced in the laboratory. It is highly reactive with oxygen (ignites spontaneously upon drying and exposure to air) producing compounds like P4O6 (phosphorus pentoxide) and P4O10 which upon contact with water becomes oxophosphoric acids (alternatively direct reaction with water can lead to phosphoric acid HPO4 through some intermediate compounds)…
“Health impact …. cause death and injury when inhaled, ingested, or had contact with the skin (whether after burns or without burning) …White phosphorus burns can be lethal due to absorption of WP from the burned surface “which may result in multi-organ failure (mainly liver and kidneys)… Sudden death after phosphorus burns…Patients who survive for more than a week usually exhibit significant changes in fat and protein metabolism (including fatty degeneration) and severe jaundice … When WP burns in the air in conditions of high oxygen, it generates smoke with an average aerosol mass concentration between 2,500 and 3,000 mg/m3, with the major components being polyphosphates, phosphine, and elemental phosphorus… Acute (5-30 minute) exposures to WP smoke caused deaths in experimental rats, mice, guinea pigs, and goats at concentrations of orthophosphoric acid and phosphorus pentoxide well below those that occur in military usage …and [there is also the health effect from] the persistence of particles of WP in the environment”
…What kind of psychopathic mind designs these weapons?
and there are other weapons as well: Is Gaza a Testing Ground for Experimental Weapons?
