Additionally, the company removed accounts and pages on Instagram and Facebook followed by a total of 235,000 people, based on a tip from USA law enforcement that exhibited similar behavior to what is described above.
Facebook removed 289 pages and 75 accounts it says were engaged in inauthentic behavior in one of the operations.
In a blog post, Nathaniel Gleicher says that the problematic pages came from Russian Federation, and operated in the Baltics, Central Asia, the Caucasus, the Ukraine, as well as in Europe.
The disinformation campaign, Facebook revealed, was "linked to employees of Sputnik, a news agency based in Moscow".
The company claimed that employees from Kremlin-backed agency Sputnik were operating the accounts, and frequently posted about topics such as anti-NATO sentiment, protest movements and anti-corruption.
"We're taking down these Pages and accounts based on their behaviour, not the content they post", Gleicher continued.
This network had grown an audience of around 180,000 followers on Facebook, with another 55,000 people following the Instagram pages.

Previous investigations in the U.S. found Facebook had been used by Russian Federation to post content that aimed to influence and interfere with the 2016 USA presidential election.
"In these cases, the people behind this activity co-ordinated with one another and used fake accounts to misrepresent themselves, and that was the basis for our action".
The propaganda pages ran ads, according to Facebook, spending roughly $135,000 with the tech company, paid for in euros, rubles, and American dollars. The first ad ran in October 2013, and the most recent ad ran in January 2019.
"Given the possibility that the Armenian page might be blocked too, we ask you to follow our news" on Telegram, VKontakte, Twitter, and other platforms, Sputnik told its readers in a statement on Facebook.
"We identified some technical overlap with Russia-based activity we saw prior to the U.S. midterm elections, including behavior that shared characteristics with previous Internet Research Agency (IRA) activity", Gleicher wrote. This group spreading misinformation originated in Russian Federation, but operated from Ukraine.
Russian actors used an array of Instagram posts to suppress Democratic votes in the lead-up to the election, cybersecurity firm New Knowledge (NK) noted in a December report to the Senate Intelligence Committee.
"We are committed to making improvements and building stronger partnerships around the world to more effectively detect and stop this activity". The disinformation campaign reached hundreds of millions of U.S. users on Facebook and other social media sites, prompting each of those companies to toughen its policies.
