(AFP) Iranian ministers should be punished if they deliberately failed to censor online content by "trouble-makers and enemies", said the head of the country's cybercrime committee on Friday.
"The order to block all channels on encrypted messaging service Telegram, that in recent days incited the population to violence and trouble, was transmitted by judicial officials to the telecoms ministry a long time ago, but unfortunately nothing was done," said Abdolsamad Khoramabadi, according to local media.
"If it is proven that officials voluntarily refused to take the necessary measures to prevent the activities of trouble-makers and enemies, they must be punished," added Khoramabadi, who is also deputy to Iran's chief prosecutor.
Telegram and Instagram were blocked shortly after protests began on December 28, and officials also moved to shut down privacy software widely used to get round online restrictions.
Khoramabadi claimed there were 8,500 channels on Telegram with content that was against "national security, the values of Islam and public morale".
"The former minister and the current minister have resisted in the face of orders" to block these channels, he said.
