Hundreds of people in Iran have been arrested or questioned for their "immoral use" of the internet, a news report said Tuesday.
Some 450 internet users were caught in the sweep by the cybercrime division of the Revolutionary Guard, the Tabnak news portal reported.
They were accused of posting immoral or un-Islamic messages on social networks such as Telegram or Instagram, which allegedly denigrated the country's family values.
In May several people were arrested for posting pictures of women online without head coverings. It is a crime in Iran for a women to go out in public without a headscarf.
While the administration of reformist President Hassan Rowhani is less hardline on such activities, the Revolutionary Guard and the Justice Ministry continue to apply the law strictly, as part of measures to protect the country from a "Western cultural invasion."
