No one who has seen the picture could possibly forget it. A nine-year-old girl, her clothes stripped off and her mouth open in a scream of pain and terror, fleeing her burning village in Vietnam with her siblings and neighbours.
The photograph is said to have changed the course of the Vietnam war and has become one of the enduring images of the human toll exacted by the conflict.
That war is long over now, but for Kim Phuc Phan Thi it will dominate and haunt her forever. For 50 years she’s carried the scars – both physical and emotional – of the day her village was napalm-bombed.
