From an interview to Lieutenant Colonel Steve Boylan, spokesperson for the U.S. military in Iraq:
AMY GOODMAN: So are you confirming that you used white phosphorus in Fallujah, but saying that it's simply not illegal?
LT. COL. STEVE BOYLAN: White phosphorus has been used. I do not recall it was used as an offensive weapon. White phosphorus is used for marking targets for both air and ground forces. White phosphorus is used to destroy equipment and other types of things. It is used to destroy weapons caches. And it is used to produce a white smoke which can obscure the enemy's vision of what we are doing.
AMY GOODMAN: And you're using it in Iraq?
LT. COL. STEVE BOYLAN: We have used it in the past. It is a perfectly legal weapon to use.
