Iran has ordered internet companies to block the encrypted messaging app Telegram, which has an estimated 40 million users in the country. Officials had previously pledged to block the app for national security reasons.
Iran's judiciary ordered the popular Telegram instant messaging app be shut down to protect national security, state TV reported on Monday.
The order follows a temporary ban introduced by the government in January after dissidents used it to organize protests.

'Against the establishment'?
"Considering various complaints against the Telegram social networking app by Iranian citizens and based on the demand of security organizations to confront the illegal activities of Telegram, the judiciary has banned its usage in Iran," state television reported when announcing the decision on Monday.
Mizan, the website of Iran's judiciary, reported that authorities had ordered the app's shutdown for actions that "included propaganda against the establishment, terrorist activities, spreading lies to incite public opinion, anti-government protests and pornography."
Telegram had just been returned to Iran and several other countries after servers in the company's home base of Dubai overheated at the weekend: "The service is now restored for most of Europe, Africa, Russia and CIS," Telegram's social media team wrote on Twitter Sunday, referring to the Commonwealth of Independent States, "Iran and Middle East coming soon."
Possibly preemptive measure: Media speculate that authorities finalized their ban on the service ahead of the May 12 deadline for US President Donald Trump to decide whether he will renew sanctions relief for Iran in accord with the 2015 multination deal reached by his predecessor, Barack Obama. Should Trump refuse, the effects on the domestic economy could see Iranians take to the streets to protest their government all over again.
Fits a pattern
Iran is also currently at the center of several regional disputes, having engaged Middle East rivals by proxy in the civil wars in Yemen and Syria, in addition to attempting to providing a stabilizing role in Iraq.
The order by Iran's judiciary came as people have taken to the streets in Russia to protest a block on the Telegram service there and even the leaders of states less frequently described as rogue have set their sights on putting an end to encrypted user-to-user communications.
The domestic alternative
Officials have encouraged Iranians to use domestic alternatives to Telegram in advance of the ban, including the new Soroush app. However, many people fear that the security services may have built spying capabilities into such apps and have proved reluctant to use them.
