The report by IRNA says the defendants are convicted of plotting against national security, spreading propaganda against the ruling system and insulting officials. It did not identify the defendants or the Facebook pages.
The report said today that the court issued its verdict against the eight young Facebook activists in April following several court appearances.
Facebook is officially banned in Iran, as are other popular social media websites like Twitter and YouTube. Their mobile apps are banned as well.
Many Iranians manage to access the banned sites through VPNs and proxy servers.
