Here are some of the questionable tweets that Twitter says were linked to the Russian government during the 2016 US election

Twitter's internal review of the activity on its platform during the 2016 US presidential election led to the identification and suspension of accounts that were "potentially connected to a propaganda effort by a Russian government-linked organization," according to a blog post from the company.

Twitter identified an organization it said took park in propaganda efforts; the Internet Research Agency (IRA) - also referred to as Russia's "troll army."

Twitter said it emailed notifications to 677,775 users who interacted with tweets originating from IRA during the election period. The social-media platform also said that it identified automated Russia-based accounts during the course of its investigation.

Although Twitter alleges that the number of Russian-linked accounts that tweeted election-related content during the election represented a small fraction of the total accounts on Twitter, it acknowledged that "any such activity represents a challenge to democratic societies everywhere."

"Twitter is committed to providing a platform that fosters healthy civic discourse and democratic debate," the company's blog post said.

Though the questionable accounts were suspended and the published content was no longer available, the company provided some examples of the content that "received significant engagement."

Here are some examples of the Russian government-linked tweets that Twitter users shared during the election:
