Facebook has controversially removed the iconic image of a girl fleeing a Napalm attack during the Vietnam war from a post, on the grounds of nudity, reports BBC.
The editor of Norwegian newspaper Aftenposten said the entire post, which was about iconic war imagery, was later deleted and the account of the reporter behind it suspended.
Espen Egil Hansen has accused Mark Zuckerberg of "an abuse of power". Facebook said it has to restrict nudity for cultural reasons.
Mr Hansen said the image of Kim Phuc, then aged nine, was removed less than 24 hours after the newspaper received a request from the firm to either take down the image or pixelate it and before it had responded.
"While we recognise that this photo is iconic, it's difficult to create a distinction between allowing a photograph of a nude child in one instance and not others," Facebook said in a statement.
"We try to find the right balance between enabling people to express themselves while maintaining a safe and respectful experience for our global community. Our solutions won't always be perfect, but we will continue to try to improve our policies and the ways in which we apply them."
Several Norwegian politicians, including Prime Minister Erna Solberg, also shared the image but within hours it had been removed again, Aftenposten reports.
Mr Hansen has written an open letter to Facebook chief executive Mark Zuckerberg.
