On November 12, 2004, the U.S. Department of Defense issued a denial of the chemical weapons charge, stating:
"The United States categorically denies the use of chemical weapons at anytime in Iraq, which includes the ongoing Fallujah operation."

Jeff Englehart, described as a former US soldier who served in Falluja, tells of how he heard orders for white phosphorus to be deployed over military radio - and saw the results.
"Burned bodies, burned women, burned children; white phosphorus kills indiscriminately... When it makes contact with skin, then it's absolutely irreversible damage, burning flesh to the bone," he says.
