U.S. State Department admits to use of white phosphorus in Fallujah

In response to video released by Italian television of the use of white phosphorous in Fallujah, and a U.S. Army trade article that specifically cites the use of white phosphorus for "lethal missions", the U.S. State Department has released the following update to their previous denial:
"White phosphorous shells, which produce smoke, were used in Fallujah not for illumination but for screening purposes, i.e., obscuring troop movements and, according to an article, "The Fight for Fallujah," in the March-April 2005 issue of Field Artillery magazine, "as a potent psychological weapon against the insurgents in trench lines and spider holes …."
The article states that U.S. forces used white phosphorous rounds to flush out enemy fighters so that they could then be killed with high explosive rounds." But in the Battle Book of the US Army Command and General Staff College, Section 5-11 (b4), it also states: It is against the law of land warfare to employ WP against personnel targets.
