Twitter shut down over 200 accounts linked to Russian government operatives, the company said Thursday, in response to mounting evidence that the platform was used extensively to sow discontent and misinformation in the United States on behalf of the Kremlin.

Facebook announced similar news, saying it had deactivated roughly 450 Facebook accounts for similar activities sponsored by the Russian government. Some of the Facebook and Twitter accounts were directly related.

The news paints a clearer picture of what the intelligence community has been referring to when it cites “Russian efforts to interfere with our democracy,” “the 2016 election,” or other similar themes.

In exclusive reports on CNN and The Daily Beast, those organizations showed that entities acting on behalf of the Russian government had bought ads to be placed on Facebook that carried both Islamophobic and pro-Black Lives Matter memes and fake news, and targeted them to appear in politically charged locations throughout the country, like Baltimore and Ferguson, Missouri.
