Facebook has been disclosing such purges more regularly in recent months, including ones linked to groups in Myanmar , Bangladesh and Russia .
Facebook said Thursday the accounts spent about $30,000 on advertisements, paid for in U.S. dollars, British pounds, Canadian dollars and euros.
Such cooperation can help the companies avoid regulatory scrutiny by showing critics and lawmakers that they can set aside differences when it comes to battling outside threats that affect their users.
The latest removed accounts, Facebook said, typically represented themselves as locals in various countries, often using fake accounts and posting news stories on current events. This included using stories from Iranian state media about conflicts in Syria and Yemen.
