Following a report from US cyber-security firm FireEye, Facebook has removed 652 pages, groups, and accounts associated with social media influence campaigns coming out of Iran.

The purpose of this campaign was to promote anti-Saudi, anti-Israeli, and pro-Palestinian narratives, but also support US policies favorable to Iran, such as the US-Iran nuclear deal (JCPOA), which President Trump has recently withdrawn the US from.
