Marie-Louise Gumuchian, who reported on Africa, Europe and the Middle East from CNN's London bureau, was terminated after one of her stories was flagged during the editing process last week.

CNN was still investigating, but the company said in an editor's note that the instances of plagiarism found in Gumuchian's articles have been removed.
"Trust, integrity and simply giving credit where it's due are among the tenets of journalism we hold dear, and we regret that we published material that did not reflect those essential standards," the note read.
