Unblocking Telegram
Iran's Telecommunications Minister says Telegram would only be unblocked if it removed "terrorist" content after the social media app was shut down during this week's protests, reports AFP.
"I had mail exchanges with the head of Telegram and I told him that the continuation of Telegram's activities is conditioned on the suppression of terrorist content," Mohammad-Javad Azari Jahromi told state television.
"The organs of power welcome criticism on social media... but in the current climate, in particular on Telegram, there is propaganda for violent and terrorist actions," he added.
More than 40 million Iranians have smartphones in the country of 80 million, and at least 25 million use Telegram on a daily basis.
