Facebook said took down hundreds of accounts from Iran that were part of a vast manipulation campaign operating in more than 20 countries.

Presence on Facebook and Instagram: 262 Pages, 356 accounts, and 3 groups on Facebook, as well as 162 accounts on Instagram.

8 events were hosted. The first was scheduled for May 2014, and the most recent was scheduled for May 2018.
