Seems clear that someone has been using White Phosphorus - Phosphorus claim after fatal air strikes in Afghanistan :
Dr Mohammad Aref Jalali, the head of an internationally funded burns hospital in Herat, said villagers taken to hospital after the incident had "highly unusual burns" on their hands and feet that he had not seen before. "We cannot be 100% sure what type of chemical it was and we do not have the equipment here to find out. One of the women who came here told us that 22 members of her family were totally burned. She said a bomb distributed white power that caught fire and then set people's clothes alight."

Sadly, in the light of previous incidents and previous denials about stuff like that, the claim that it was the Taliban and not the US, has to be regarded with suspicion.

"...members of the human rights department at the UN mission in Afghanistan have been appalled by witness testimony from people in the village, according to one official in Kabul who talked anonymously to the Guardian.

"He said bombs were dropped after militants had quit the battlefield, which appeared to be backed up by the US air force's own daily report, which is published online. "The stories that are emerging are quite frankly horrifying," the official said. "It is quite apparent that the large bulk of casualties were called in after the initial fighting had subsided and both the troops and the Taliban had withdrawn.

"Local villagers went to the mosque to pray for peace. Shortly after evening prayers the air strikes were called in, and they continued for a couple of hours whilst the villagers were frantically calling the local governor to get him to call off the air strikes."
