An aide to Norwegian Prime Minister Erna Solberg says Facebook removed her post with an iconic 1972 image of a naked girl running from a napalm attack in Vietnam.

Sigbjorn Aanes says the post with the photo was removed Friday. Aanes told The AP that "Facebook cannot continue to censor world history."

The Pulitzer Prize-winning image by Associated Press photographer Nick Ut is at the center of a heated debate about freedom of speech in Norway after Facebook deleted it from a Norwegian author's page last month.

Many Norwegians have since posted the photo on Facebook in protest, and Solberg joined them on Friday.
