And three others wounded 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 2a hours. Our correspondent Rana Rahimpour from the Bbcs Persian Service has the latest. Once again, 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. I am joined from washington dc by alireza nader, Senior International policy analyst at rand corporation. Thank you forjoining us. These are not the first st protests under rouhanis presidency. Do you believe these are different . Yes, they are very different to 2009 because we are seeing this all over iran, especially in smaller, mid size cities, and this time around this is not just about an election, as cities, and this time around this is notjust about an election, as it was in 2009. These are people who are crying for the Islamic Republic to be overthrown. I believe this is the most serious challenge to the Islamic Republic since 2009, not really since 1979, this is huge. Significant. We have had now five days of protests, 13 reported killed. Where do you see this going . It is very hard to tell. I dont think the iranian government at this point can do anything to address the peoples anger, unless it manages to dramatically improve the economy in the next few months, which i do not think will happen. I think this has demonstrated that the people of iran are fed up with the entire system, regardless of conservative or centrist leaders like rouhani. I think they have had enough. And is it that you think that there is such a big disconnect between the people on the streets and those in power, oi on the streets and those in power, or do you think that the people in power dont really care . Or do you think that the people in power dont really care . |j or do you think that the people in power dont really care . I think they care, because their own lives and survival is really on the line 110w. And survival is really on the line now. Iran has a history of overthrowing its governments. And there are currently able in power, including president rouhani, and the supreme including president rouhani, and the supreme leader, overthrew assad, they were part of a revolution, so they were part of a revolution, so they know a revolution could happen again but they have chosen the wrong method to address grievances, they have resorted to aggression and that no longer works in iran. And what is it using the outside countries be doing . I think european countries, the most important thing to do is to warn the iranian government not to use force against the protests. The european union, the united kingdom, france, germany have Major Economic pressure on iran and it can pressure iran not to use force against the protests. From the rand corporation, thank you very much indeed. California has become the largest state in the us to legalise the Recreational Use of cannabis. It promises to be a cash crop, and state and local governments could collect a billion dollars a year in tax revenue. But opponents say the new law will lead to more driving under the influence of the drug and introduce young people to drug use. Heres cbs reporter danielle nottingham. A Ribbon Cutting ceremony kicked off the historic day at the dispensary in oakland where hundreds of people lined up to buy recreational pot, starting at 6am. Harbourside is one of the first shops in california to get their new city and state permits. Henry was the first customer. It has been a long time coming. California joined seven other states and the district of columbia, where Recreational Marijuana is legal. Massachusetts is set to begin sales injuly, but california is the largest market in the nation and that has many other states watching closely. It is going to send a message to other states that legalisation, regulation and taxation of marijuana is the correct Public Policy decision, and that it works. Buyers have to be at least 21 years old and can only purchase up to one ounce of Recreational Marijuana. Recreational pot also costs more than medical marijuana because of a higher tax. Users say they want to end the stigma surrounding pot use. I am an employed, functioning adult and i also smoke weed, and i dont think theres anything wrong with that. With the addition of recreational sales, the industry in california is expected to generate at least 1 billion in tax revenue annually. Danielle nottingham, cbs news. Air accident investigators in australia say it could take months to establish why a seaplane carrying a prominent british businessman and four members of his family crashed into a river near sydney on new years eve. Richard cousins died, along with his fiancee and her daughter. The pilot was also killed as well as mr cousins two grown up sons. Joining me from rose bay in sydney where the planes operator is based is our correspondent phil mercer. Obviously that timeline for it taking months, is it based on the fa ct taking months, is it based on the fact that the wreckage of the plane is so deep . Well, thats part of the issue. The air crash team dont see that as a major problem. But of course the aircraft that lies in about 30 metres of water in the hawkesbury river, which is about a 20 minute flight from here, the aircraft, by the way, would have taken from rose bay, that you see now on your screen. And of course, the aircraft will be the biggest clue for air crash investigators. Their work will be slow, their work will be painstaking, and of course the maintenance, the age of the plane, the experience of the pilot, the behaviour of the pilot in the weather conditions, all of these factors will come into play as the Australian Transport Safety Bureau investigates this accident and it is theirjob to piece together the different factors to try to work out what happened and why. And it looks quiet behind you. They have stopped operating seaplanes at the moment have they . This is the terminal at rose bay for sydney seaplanes and on the door there is a notice that says that the company has been operating since 2005, but that all services have been temporarily suspended until further notice because of this investigation. The company has also said that it has had an unblemished safety red Safety Record and that the pilots were some of the most experienced in the world. It is extending its sympathies to the families of richard cousins, 58 yea rs of families of richard cousins, 58 years of age, very prominent businessman, he died along with four members of his family and as you say air crash investigators here in australia say that it could take considerable time to come up with the answer is that not only mr cousins family want to know but the broader aviation and Tourism Industry and the community in general. Thank you. Here in the uk, eye witnesses have been describing a huge fire those attending helped get the horses to safety. Ijust took it upon myself. It was soon a huge blaze. Merseyside fire and rescue say its one of the worst theye ever dealt with. This was a challenging incident. The fire burned for much of the night. And after the fire had been put out this morning, after many hours, some dogs, which had been left in those cars were safely rescued and reunited with their owners. As the dogs were handed back to their owners, there was a hug of gratitude for the firefighters. The insurance bill will run to millions of pounds but thankfully no one was hurt.

More than 300 women from hollywoods Entertainment Industry have launched an initiative to tackle Sexual Harassment in workplaces. The campaign, called times up, aims to improve legislation and corporate policies, increase access to legal assistance, and help more women reach the top levels of industry. It is supported by stars including meryl streep, jennifer lawrence, and cate blanchett. In an open letter printed in the new york times, the women argue that the experiences of women working in less glamorous jobs, like farming and catering, deserve the same attention as those in the Entertainment Industry. Joining me now from santa monica is filmmaker mitchell block. Thank you forjoining us. I suppose really all of this started some time ago, and then there was the Harvey Weinstein scandal. Has hollywood changed irreversibly since then, do you think . I think all of america has. One can no longer ignore paedophiles or any kind of sexual abuse in the workplace. Notjust in hollywood, but in every field. Are there any other particular industries where you think Sexual Harassment is almost commonplace . think in any industry where men and women work in the same workplace. Its just an outcome of bad behaviour on the part of participants. Hollywood isnt unique. It is simply more visible. And, with regard to what can be done, donald trump hasnt really set a great deal about it yet, but the mood of the people in america does seem mood of the people in america does seem to be certainly changing. dont expect donald trump to be saying much about Sexual Harassment, considering his own record. But of course, he has denied all those allegations put against him. What are people at the. General people around the country feel, that you have come into contact with . around the country feel, that you have come into contact with . I think eve ryo ne have come into contact with . I think everyone is always amused by hollywood. But hollywood simply reflects ourselves. And because we are so reflects ourselves. And because we are so visible, hollywood is hard to ignore. But, when you have an actor oran ignore. But, when you have an actor or an actresss career destroyed because of allegations, it makes it very challenging for all of us. Thank you very much.
