Facebook on Thursday began placing warning notes on pages, posts, and advertisements by a number of North Korea-linked organizations, as part of a broader push against state-sponsored disinformation on the influential social media platform.

Alongside prominent state-run media from Russia and China, outlets such as DPRK Today have begun to be labeled with information panels that state the content’s country of origin and a warning that the “publisher is wholly or partially under the editorial control of a state.”

“This is determined by a range of factors, including but not limited to funding, structure and journalistic standards,” the warning reads.
