After a fifth day of Anti Government protests. It is the first death of a member of the Security Forces and represents a significant escalation in the unrest. What began as a protest against the rising cost of living now seems to be taking on political overtones. A dozen protesters have been killed in the last twenty four hours. Our correspondent rana rahimpour, from the bbcs persian service, has the latest. Once again, across iran, thousands of people have taken to the streets. A poster of the countrys Supreme Leader, ali khamenei, set alight and then torn down. They are angry at unemployment, rising prices and what many of them see as widespread corruption. Its the boldest challenge to the countrys leadership in nearly a decade. The demonstrations began in the North Western city of mashhad, a key base for the most outspoken critics of president rouhani. But it has quickly turned into a widespread anti establishment movement, including the Supreme Leader. This is the biggest show of dissent in iran since the post election rallies of 2009. They were large in size, but limited to urban areas of the country, like the capital, tehran. This time, the protests are more widespread, with towns and cities all over the country looking for social, political, and economic change. Authorities are continuing to suspend social media platforms out of fear theyll be used to organise protests. The bbc has received reports of text messages, like this one, being sent to people urging them not to take part. A handful of pro government marchers are attempting to counter the wider demonstrations, but with limited information coming out of the country, its difficult to gauge how many people are involved. In the last 2a hours, president rouhani has spoken out twice against the protests. Downplaying their significance. Instead, accusing irans enemies of instigating the unrest. Translation our victory against the us and its regime is unbearable for our enemies. Our success in the region is intolerable for them. They are after revenge and are trying to provoke people. But his words have failed to calm the situation. In certain areas of the country, unemployment is as high as 60 , and reports of extreme corruption have iranians frustrated and hungry for change. And tonight, Iranian State tv is reporting that a Police Officer has been shot dead. It is the first reported attack on a member of the Security Forces since the demonstrations began last week. A move that may escalate the confrontation between protesters and the state and potentially, lead to more bloodshed. Rana rahimpour, bbc news. Alex vatanka is a senior fellow at the middle east institute in washington dc. Why is there such a disconnect between the government and ordinary people . If you go back to may of this year when the president was re elected with a landslide 2a million voters backing him, they voted for him because he made a simple but powerful promise. He said there would be more Political Freedoms in this country. He has not delivered on that at all but turned away from the grass movements and turned to the hardliners looking for accommodation. After his re election he forgot the ordinary men and women of iran and set his eyes on the top job of the country, the position of the Supreme Leadership. When the current supreme the Supreme Leadership. When the current Supreme Leader passes on, rouhani would like to take on his job. He goes to hardline elements and in this process he forgot the people, the painful Economic Conditions of the country and what we are witnessing run out is a result of that neglect by rob one this is not about what one, it is about the Supreme Leader. The president. As we are watching on our tv screens, the people are saying the only way that seems to work with this regime is it they can see you on the street otherwise they do not Pay Attention to us. In the past outsiders have been blamed for the fate befalling the country. People now weary of that as an excuse . Iranians have always been worried about what happens in what is happening in the neighbourhood, in places like iraq and syria, happening to them. Iran is a large multi ethnic country. There has was being that worry that such conditions as seen elsewhere could come to iran if the stability of the country is put at risk but, at the same time, they are asking themselves, from watching on what i can tell, they are saying, at what point she would have to ask ourselves the simple question of how much more can we put up with these . If it is a risky project to embark upon and seek to come on to the street to get the authoritys attention, lets do it that way and thatis attention, lets do it that way and that is where we are today. The idea that is where we are today. The idea that some foreign entity, in europe, in america or elsewhere, is responsible is a fanciful idea. Listen to what the people are saying. The idea that this is all instigated by a Central Point somewhere in the planet, isjust the authorities putting their head in the sack. California has become the largest state in the us to legalise the Recreational Use of cannabis.

Bearing in mind this issue has been opened up to other professions and industries, any from the president . Well, we have not heard anything from the president on this issue today and, of course, it is well known he was accused during his campaign of sexually harassing a number of women. There are a number of allegations against him. He has been rather quiet on this issue of Sexual Harassment, certainly in hollywood and the wider workplace, but i am sure that one of the goals of organisations like this will be to highlight this issue on a political level and that includes the president and the senate as well.
