The Associated Press reported that Iran also experienced wide disruptions and outages of internet service on Friday and Saturday, according to the group NetBlocks, which monitors worldwide internet access. By Saturday night, connectivity had fallen to just 7 percent of ordinary levels, NetBlocks said.
“The ongoing disruption is the most severe recorded in Iran since President Rouhani came to power, and the most severe disconnection tracked by NetBlocks in any country in terms of its technical complexity and breadth,” the group said. The internet firm Oracle called it “the largest internet shutdown ever observed in Iran.”
Ahmad, a taxi driver in Tehran who did not want his last name used, said in telephone interview that when he tried to connect to the internet on his mobile phone, a recorded message said that because of a decision by the National Security Council, connectivity had been cut off.
WhatsApp and Instagram, both used widely by Iranians, were also blocked.
Fahimeh, an accountant, said she and her friends relied on WhatsApp to find out the location and time of protests, and in the absence of the internet, it would be difficult for Iranians to plan and spread the word.
The Ministry of Information said Sunday that it had identified bad actors among protesters and warned that those responsible for unrest would be arrested.
Intelligence agents on Sunday arrested Abdoleza Davari, a senior aide to Iran’s former President Mahmoud Ahmadinejad and a vocal critic of the gas price policy, according to his wife, Elham Salmani. Mr. Davari had posted a tweet a day earlier saying that the people have the right to demonstrate and that parliament must hear their concerns and stand up to the branches of the government imposing this policy.
“They have failed to successfully counter freethinking with ideology so the only tool at their disposal is violence,” said Ms. Salmani, a journalist and political activist, in a telephone interview. She said the prosecutor’s office had threatened to arrest her as well and had accused her of hiding her husband’s mobile telephone and laptop computer.
Mostafa Tajzadeh, a prominent reformist politician, said on Twitter that if elected officials could not listen to the demands of the people, “they should resign and leave the country to its real rulers.”
