The social networking site has taken strong action against the 'Stop the Steal' group - which had more than 364,000 members - after it pushed false allegations that the Democrats are attempting to "steal" the US presidential election between Joe Biden and Republican President Donald Trump.
In a statement, a Facebook spokesperson said: "In line with the exceptional measures that we are taking during this period of heightened tension, we have removed the Group 'Stop the Steal,' which was creating real-world event.
"The group was organised around the delegitimization of the election process, and we saw worrying calls for violence from some members of the group."
The move comes after Twitter suspended a number of accounts posing as US news organisations and prematurely declaring election wins.
The accounts in question copied the names and logos of the Associated Press - and at least one as CNN - which most tweets claiming a false victory for Joe Biden, while at least one other announced the same for President Donald Trump.
As reported by the Wall Street Journal, a Twitter spokesperson revealed the accounts have been permanently suspended for violating the site's impersonation policy.
Under the rules, users are prohibited for posing "as another person, brand, or organisation in a confusing or deceptive manner".
