Lasers may ease pain for 'napalm girl'

In the photograph that made Kim Phuc a living symbol of the Vietnam War, her burns aren't visible - only her agony as she runs wailing toward the camera.

Her arms are flung away from her body, which is naked because she has ripped off her burning clothes.

More than 40 years later she can hide the scars beneath long sleeves, but a single tear down her otherwise radiant face betrays the pain she has endured since that errant napalm strike in 1972.
