The Italian TV network RAI is airing a special called La Strage Nascosta (The Secret Massacre) on the American use of incendiary weapons on civilians in Fallujah, specifically white phosphorus and a new variant on napalm(!) called MK-77.
White phosphorus, ostensibly used for "illuminating the battlefield" (sorta like how napalm was used in Vietnam as a "defoliant"), doubles as an effective way to torch everything (or everyone) in a 150 meter swath. Once it touches skin, it attaches and burns all the way to the bone, sometimes leaving the clothing around the wound intact.
And if you try to wash it off, it re-ignites.
WP and MK-77 can't be targetted precisely, however, so they wreak indiscriminate destruction wherever they are dropped. Thus, the use of such incendiaries against civilian populations is prohibited by Protocol III of the Geneva Convention.
Here's the video (it's available in Italian, English, and Arabic). It includes interviews with American soldiers and Iraqis, video footage of Americans using white phosphorus, and pictures of Iraqi dead killed by WP and MK-77. Warning: the video is very graphic. Put your kids to bed before you watch it.
