A fake news company with ties to Russian officials shut down the social media platform that the company claimed was behind the spread of fake news stories on Thursday.

The company, which was backed by a Russian oligarch, also claimed to be working on a rival to Twitter, despite its own history of being accused of being a front for Russian state propaganda.

In a statement posted to Twitter’s official Twitter account, Twitter said the company had removed “fake news sites” from its platform after it learned about their alleged involvement with Russia.

Twitter said it would now use its own data to help identify the “bots and bots accounts” that spread misinformation about the U.S. election.

The statement said Twitter has worked closely with law enforcement and intelligence agencies since the election to prevent misinformation on the platform and had already removed “a significant number of accounts.”

The company added that it has “conducted extensive research and development” to identify and remove bot accounts from the platform.

Twitter did not provide details about how many accounts had been banned, and how many had been removed.

The removal came a day after President Donald Trump and the intelligence community announced they were looking into Russia’s role in the election.

Trump and intelligence officials have denied any involvement with Russian election interference.

Twitter’s suspension comes after it was revealed the company was working with the Department of Homeland Security and other law enforcement agencies to identify bots and other “bots” who spread misinformation during the election campaign.

Twitter also announced it would be revamping its tools to better detect and prevent false accounts from using its platform.

In its statement, Twitter stressed that its decision to remove fake news sites was “a necessary and important step to protect our users and ensure that fake news is not spread by people with malicious intent.”

Twitter did note that it was “aware of the fact that some fake news outlets on the Internet have been promoting misinformation in our platform.”
