Nathaniel Gleicher, Facebook’s head of cybersecurity, said: “We’re constantly working to detect and stop this type of activity because we don’t want our services to be used to manipulate people.
“Policy, as is always the case with these takedowns, is we’re removing these pages, groups and accounts based on their behaviour, not the content they posted.
“Based on a tip shared by FireEye, a US cybersecurity firm, we conducted an internal investigation into suspected Iran-linked coordinated inauthentic behaviour and identified this activity.
“We’ve shared our analysis with law enforcement, policymakers and industry partners.”
Last month it was reported that Iran carried out a number of cyber attacks on the Post Office and the UK’s local government networks in the lead-up to Christmas.
