After a half-century of public silence, a freelance photographer from Vietnam has asserted he took one of the most renowned and impactful photos of the 20th century — the image of a naked girl fleeing a napalm attack in South Vietnam that has long been credited to a staff photographer from The Associated Press.

Nguyen Thanh Nghe claimed authorship of the Pulitzer Prize-winning "napalm girl" photograph in the new documentary "The Stringer" and on the sidelines of its premiere Saturday night at the Sundance Film Festival in Park City, Utah.

The AP conducted its own investigation and said it has no reason to conclude that anyone other than the long-credited photographer, Nick Ut, made the picture.

The news agency said it was "surprised and disappointed" that filmmakers portrayed it as having reviewed the film's materials and being dismissive. The AP said it saw the film for the first time at Sundance.

Nghe joined the filmmakers for the post-screening Q&A where he said, through a translator, "I took the photo." The audience cheered enthusiastically. He did not say why he waited so long to make the claim.

The AP said it was calling on the filmmakers to release their contributors from non-disclosure agreements for the film, including Nghe. It also called on the filmmakers to share a visual analysis they commissioned — and the film itself. "We cannot state more clearly that The Associated Press is only interested in the facts and a truthful history of this iconic photo," the agency said.
