The company's CEO Pavel Durov tweeted that Iranian authorities took action after his company refused to shut down "peacefully protesting channels". Two protesters were killed in Dorud in the province of Lorestan late Saturday during clashes with security forces, Habibollah Khojastehpour, deputy for political affairs for the province of Lorestan, said in an interview posted on the website of Iran's state broadcaster.
Iranian hard-liners who support President Rouhani, Supreme Leader Ayatollah Ali Khamenei, and the clerical establishment of the Islamic Republic came out in droves this weekend to retaliate against the demonstrators.
"Counterrevolution groups and foreign media are continuing their organized efforts to misuse the people's economic and livelihood problems and their legitimate demands to provide an opportunity for unlawful gatherings and possibly chaos", state TV said of the protests.
And when that happened, state media was also forced to acknowledge that it had not initially reported on the protests on the orders of security officials.
"Some meant to enter and damage some government places but the attackers did not manage to achieve their goals. and the town is under control", the unidentified official told the ILNA news agency.More news: 2017 at the Box Office

The protests have erupted at a time of deepening strains between Iran and the administration of U.S. President Donald Trump, who has imposed additional sanctions on Tehran and has threatened to scuttle the nuclear accord.
"This gentleman in America, who is now trying to sympathise with our nation, appears to have forgotten that he called the Iranian nation terrorists several months ago", he was reported to have said.
Since the 2009 protests against a disputed presidential election that gave hardliner Mahmoud Ahmadinejad a second term were ruthlessly put down, many middle-class Iranians have abandoned hope of securing change from the streets.
