Forty years ago a single photograph of a nine-year-old girl, her body scarred by napalm, helped swell opposition to
the Vietnam war.
The US-made product, a thickening agent mixed with petroleum or other fuel, and reaching temperatures of 1,200
degrees Celcius, was used as a weapon during the war.
The Associated Press photograph of Kim Phuc Phan Ti, who became known as the 'napalm girl' showed how the chemical burned its victims to the bone.
Kim survived and, still bearing the scars of war, she now resides near Toronto where she is a UNESCO ambassador
and an activist for the youngest victims of wars.
