The Boston Globe on Friday retracted a story by a Halifax-based freelance writer that purported to describe the opening of the seal hunt.
The story, which was published Wednesday, contained details that "hunters on about 300 boats converged on ice floes, shooting seal cubs by the hundreds, as the ice and water turned red."
However, the seal hunt was actually delayed until Friday morning due to bad weather.
The newspaper said the story should not have been published, and the Globe has discontinued use of correspondent Barbara Stewart.
"The author's failure to accurately report the status of the hunt and her fabrication of details at the scene are clear violations of the Globe's journalistic standards," the Globe said in an editor's note on its website.
"Because the freelancer was not reporting from the scene, Globe editors should have demanded attribution for any details she provided about the hunt itself," the newspaper said.
