Iran has moved to limit the social media networks that were used for the organisation of the four days of the anti-establishment protests.
The “temporary” restrictions on the app, Telegram and Instagram have been imposed to “maintain the peace”, state news agency Irib reports.
The protests were the biggest show of dissent from the big rally of 2009.
President Hassan Rouhani said that Iranians have the right to protest, but it did not cause the disorder.
The protest began in the north-east, as a cry against the economic difficulties and the increase in prices, but transformed politics in many places, with chanted slogans against the Supreme Leader, Ayatollah Ali Khamenei, Mr. Rouhani and Iran’s interventionist foreign policy in the region.
In his first public comments since the demonstrations broke out, the Iranian president, speaking at a cabinet meeting, he said that citizens were “completely free to make criticism and even protests”.
But he added that the government would not tolerate any action that has created the “social disorder”, the Iranian Students News Agency reported.
After the violence flared in many places on Saturday, it is not clear how many events are going on Sunday. Small groups are meeting in Tehran, and the police used water cannons to disperse protesters at a major intersection – as captured in a video obtained by the BBC Persian.

Why are these social network be limited?
In a rigid control of the media, most of the information about the demonstrations has emerged through social media and platforms like Telegram and Instagram were widely used by protesters.
The telegram, in particular, is very popular in Iran, with more than 50% of the country’s 80m population is said to be active on the app.
The ceo of the company Pavel Durov wrote on twitter that the Iranian authorities intervened after his company refused to stop “peacefully protesting”.

Mr Durov, said in a Telegram to the post that is one of the main foreign opposition channel, Amadnews, was blocked Saturday by Telegram after that you called for violence against the police.
He said that a new “quiet channel” – to which access is now being limited – was established for the hundreds of thousands of subscribers.
Iranian Communications Minister Mohammad-Javad Azari Jahromi, had previously accused the channel Amadnews of the promotion of “the armed insurrection and social unrest”, including the use of molotov cocktails.Where the protests lead?
Analysis Kasra Naji, BBC Persian
There is widespread and simmering discontent in Iran, where repression is pervasive, and the economic hardship is getting worse and worse – a BBC Persian survey found that, on average, the Iranians have become 15% poorer over the last 10 years.
The protests have remained confined to relatively small pockets, mostly young male protesters demanding the fall of the clerical regime.
They are spread to small towns around the country and have the potential to grow in size.
But there is no obvious leadership. Opposition figures have long been silenced or sent into exile.
Even in exile, there is an opposition figure who commands a large following. Some protesters have asked for the return of the monarchy and the former the son of shah Reza Pahlavi, who lives in exile in the United States, has released a statement in support of events. But there are signs that he is in the dark as to where these protests are going to as anyone else.
BBC Persian, which broadcasts on TV, radio and online from London, is banned in Iran, where employees and their families routinely face harassment and questioning by the authorities.There was violence?
There have been outbreaks of clashes in several cities on Saturday, and two protesters died of gunshot wounds in the western city of Dorud.
The authorities said that security forces have opened fire on protesters, and blame the death, instead of Sunni Muslim extremists and foreign powers.

Who are the militia the Basij?
Correspondents say the reference to foreign intelligence agencies, was intended as Saudi Arabia.
Iran’s Revolutionary Guards have warned the anti-government protesters they will face the nation’s “iron fist” if the political unrest continues. Dozens of people are reported to have been arrested in the past days, 200 of which are in Tehran, on Saturday night.
The islamic Body of the Revolutionary Guards (IRGC) is a powerful force, with ties to the country’s supreme leader, and is dedicated to preserving the country’s Islamic system.
Brig-gen Esmail Kowsari told the news agency Isna: “If the people were in the street in the course of high prices, they should not have sung those slogans and burnt public property and cars.”
Iran, the interior minister, has also warned the public that the protesters will be held responsible.
What has been the response, both at home and abroad?
The Iranian authorities are blaming anti-revolutionaries and agents of foreign powers, for the outbreak of protests.
But the politicians have also weighed in. Reformers tend to emphasize the right of persons to freedom of expression, while the conservatives to highlight the economic problems and accuse some of trying to hijack the protests and distract attention from economic problems to political demands.Who is Hassan Rouhani?
The US has led the international support for the protesters.
In his last tweet on the matter, the President, Donald Trump has said that the Iranians were “finally wise to how their money and wealth has been stolen and squandered on terrorism”.
Iran, the foreign minister called the previous comments by Mr. Trump and other officials from the US “opportunistic and dishonest”.What happened in 2009?
On Saturday, thousands of pro-government demonstrators turned out for a pre-organised rallies across the country to celebrate the eighth anniversary of the suppression of the 2009 protest of the street.
Those mass demonstrations – defined as the Green Movement – were in possession of millions of supporters of the opposition against the disputed election victory of president Mahmoud Ahmadinejad.
At least 30 people have been killed and thousands arrested in the wave of protests that drew the largest crowds in Iran since the Islamic Revolution in 1979.
