Iranian President Hassan Rouhani has said that Iranian citizens were completely free to express their criticism of the government or stage protests in a way that would lead to the improvement of the country's conditions but must not jeopardise security. Speaking at a cabinet session, President acknowledged that there were problems that needed to be solved but warned that violence would not be tolerated. The protests have been the biggest show of dissent since huge rallies in 2009. There have been clashes in several cities, and Iran has restricted social networks used to organise protests. The "temporary" restrictions on the apps Telegram and Instagram were imposed to "maintain tranquillity", state news agency Irib reports.<br/><br/>At least two people have been killed and dozens arrested since protests broke out Thursday in the city of Masshad and spread to Tehran and other cities. <br/>An official in Tehran said that 200 people were arrested during the protests in the Iranian capital, the semi-official ILNA news agency reported. These individuals are now with the judiciary and some others have been freed out of clemency, Ali Asghar Nasserbakht, a security deputy for Tehran's governor, told ILNA. He said 40 of those arrested were "leaders" and that their protests had not been related to the economy.<br/><br/>Meanwhile, US ambassador to the United Nations, Nikki Haley has said Iran's government is being tested by its own citizens after three days of protests in the country. She in a statement said she pray that freedom and human rights will carry the day. Haley's comments echoed those of US President Donald Trump, who earlier said the United States was watching closely for human rights violations.<br/><br/><br/>The protests began in the north-east as an outcry against economic hardship and rising prices, but turned political in many places, with slogans chanted against Supreme Leader Ayatollah Ali Khamenei, Mr Rouhani and Iran's interventionist foreign policy in the region.<br/><br/>In his latest tweet on the issue, US President Donald Trump said that Iranians were finally getting wise as to how their money and wealth is being stolen and squandered on terrorism.<br/>In his first public comments, Mr Rouhani criticised Mr Trump.''<br/>
