O insuspeito Washington Post publica um texto que aqui deixo e que fala por si e pelos crimes que por aí andam a cometer, uns. A ocultar, outros.
The BBC News website looks at the facts behind the row.
What is white phosphorus?
White phosphorus is a solid, waxy man-made chemical which ignites spontaneously at about 30C and produces an intense heat, bright light and thick pillars of smoke.
The US military says it used white phosphorus to flush out insurgents
It continues to burn until deprived of oxygen and, if extinguished with water, can later reignite if the particles dry out and are exposed again to the air.
Also known by the military as WP or Willy Pete, white phosphorus is used in munitions, to mark enemy targets and to produce smoke for concealing troop movements.
It can also be used as an incendiary device to firebomb enemy positions.
What are its effects?
If particles of ignited white phosphorus land on a person's skin, they can continue to burn right through flesh to the bone. Toxic phosphoric acid can also be released into wounds, risking phosphorus poisoning.
Skin burns must be immersed in water or covered with wet cloths to prevent re-combustion until the particles can be removed.
Exposure to white phosphorus smoke in the air can also cause liver, kidney, heart, lung or bone damage and even death.
A former US soldier who served in Iraq says breathing in smoke close to a shell caused the throat and lungs to blister until the victim suffocated, with the phosphorus continuing to burn them from the inside.
Long-term exposure to lesser concentrations over several months or years may lead to a condition called "phossy jaw", where mouth wounds are caused that fail to heal and the jawbone eventually breaks down.
How did the US use it?
The US initially denied reports it had used white phosphorus as a weapon in Falluja in November 2004, saying it had been used only for illumination and laying smokescreens.
Spontaneously flammable chemical used for battlefield illumination
Contact with particles causes burning of skin and flesh
Use of incendiary weapons prohibited for attacking civilians (Protocol III of Convention on Certain Conventional Weapons)
Protocol III not signed by US
However, the Pentagon has now confirmed the substance was used as an "incendiary weapon" during the assault.
