Iranian President Hassan Rouhani is criticizing the blocking of the popular Telegram messaging app in the Islamic Republic, suggesting those "at the highest level" in the country shut off access.

Axar.az informs citing ISNA.

Authorities temporarily blocked the app to calm the demonstrations, but Iran's judiciary on Monday ordered internet service providers to block access to the app. Since then, users largely haven't been able to access it.

Tehran's prosecutor also ordered Telegram be blocked in a way that would not allow users to bypass the restrictions using a virtual private network or other means. Computer-savvy Iranians routinely use such VPNs to get around online restrictions in the country to use Facebook, Twitter and other prohibited sites.

In a post on photo-sharing app Instagram, which isn't blocked in Iran, Rouhani wrote: "No social network or messenger were blocked 'by this government' and won't be blocked."

"If at the highest level of the system a decision has been made to restrict or block the people's communications, the real owners of this country, which are the people, should be aware of this," Rouhani added.

The semi-official ISNA news agency also reported his remarks.

Telegram allows users to send text messages, pictures and video over the internet. The service touts itself as being highly encrypted and allows users to set their messages to "self-destruct" after a certain period, making it a favorite among activists and others concerned about their privacy.
