In iran, more Anti Government protests have broken out in at least five cities. Police say one of their officers has been shot dead which is believed to be the first death of a member of the Security Forces since the unrest began. Iranian state television said that ten people had been killed overnight during demonstrations. The rallies started as a protest against falling Living Standards. But they have become political against the powerful islamic clerics who rule iran. Earlier, president Hassan Rouhani tried to play down the protests, saying they were not a threat. This report from rana rahimpour. The fifth day of protests in iran. Once again, thousands of people have taken to the streets. They are angry at unemployment, rising prices, and what many think is 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 president rouhanis most outspoken critics. And has quickly turned into a widespread antiestablishment movement. 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 they will be used to organise more 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. 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. At least 12 people have died since the protests began. And with no sign of stopping, that number looks set to rise. Rana rahimpour, bbc news. We heard from the iranian president Hassan Rouhani in ranas report. Ive been speaking about his part in this story with maziar bahari, the editor of the news website, iran wire. President rouhani does not have the power to make any substantial changes in iran. You have to understand the president in iran is like the Prime Minister and an absolute monarchy. The president is just the Prime Minister to the supreme just the Prime Minister to the Supreme Leader, who has the power and until now the Supreme Leader has been quiet and it is up to the supreme been quiet and it is up to the Supreme Leader to make any changes. But so far we have not seen any willingness from the Supreme Leader to make changes. All this started as an economic protest against falling Living Standards and has now clearly become political, a lot of anger directed at the all powerful clerics, the supreme at the all powerful clerics, the Supreme Leader as well. How do you think the leader and clerics will be filling about all this, will they be trouble at all . The protest started as a demonstration manifestation of angen demonstration manifestation of anger, frustration of people across iran against the clerical rule in the past four decades. As such, the clerics and the Supreme Leader will not be able to satisfy people because if they want to satisfy people they have to be overthrown and they do not want that. So of course the Supreme Leader is trying to appease people to a certain extent but when people come to the streets as they have done in the past five days and chant against them, that means they do not want him to be in power. Iforesee the supreme him to be in power. Iforesee the Supreme Leader asking the revolutionary guard to suppress peoples protests across iran in the foreseeable future. North koreas leader kimjong un has said a Nuclear Launch button is always on his table and warned the us it will never be able to start a war. In a televised speech he said the entire us was within range of north Koreas Nuclear weapons, adding this is not blackmail but reality. But he also offered a potential olive branch to south korea, suggesting he was open to dialogue. It follows months of escalating tensions over his countrys Weapons Programme and an angry exchange of insults with us president donald trump. Sophie long reports from seoul just after the first sun of 2018 rose over the korean peninsula, kim jong un delivered his new years address live on state run television, with an unsurprisingly defiant message for the United States. Translation the entire United States is within range of our Nuclear Weapons and the Nuclear Button is always on my desk. This is reality, not a threat. Perhaps more surprising was the olive branch he appeared to offer his neighbour, south korea. He said he hoped the Winter Olympics theyre about to host would be a success. And said he was considering sending a delegation to the games. That comes as music to the ears of violinist won hyung joon. For ten years, hes tried and failed to organise a peace concert with these young south koreans playing together with north korean musicians. He now hopes to make that happen at the pyeongchang opening ceremony. We have hope that the olympics is coming, and everyone is coming, and its beyond, you know, political difficulties. So, i really wish north korea will come, and especially with musicians, and well be able to play together. The south korean government has welcome to the appeal for dialogue, saying it, too, is willing to engage. After a year of Nuclear Tests and missile launches, young People Living in seoul welcomed the new year, writing down their wishes with hope that tensions might now reduce, if only in the very immediate future. I feel optimistic, i think everything is attitude, and if we go in here with the right attitude, the right approach, i think we can solve the situation. As a citizen of this country, thats all i can really wish for. It is obvious to anyone in the world that we are in a very tense situation right now. And i think that means we have hope for the future. Sophie long, bbc news, seoul. Lets take a look at some of the other stories making the news. Israeli Officials Say a planned visit by the us Vice President , mike pence, has been postponed indefinitely. He had originally been due to go in december, but the trip was rescheduled after president trumps recognition ofjerusalem as the israeli capital sparked widespread unrest.

Last month a facebook video that was widely circulated, showed her slapping an israeli soldier in the occupied west bank. The incident reportedly happened shortly after the teenagers cousin had been seriously injured by a rubber bullet. The spanish economy minister has put the cost of the Catalan Independence crisis at around 1. 2 billion.

California today becomes 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 narcotics use. Heres cbs reporter carter evans. As holder of the very first state licensed to sell recreational this shop is a 1 to we did. Padsaggg we did. Packaging 5 we did. Padsaggg ยง changing so it is not packaging is changing so it is not see through.

Com the 1st of january the general Recreational Marijuana. Com the 1st ofjanuary the general public will not be able to come into medical shops like this to buy it. This person runs the view of cannabis control. It will take some time for businesses to get up and running but we ask people to be patient. California Highway Patrol officers are also pressing for Legal Marijuana and getting the word out driving while smoking marijuana is illegal. Did you know smoking a joint could get you a gui . Authorities expect to see an increase in cannabis related crashes, just like other states where the drug is legal. If you can buy a drink or a joint, you can also for a taxi. Then you can also afford a taxi. A short while ago, cbs reporter Jessica Flores spoke to me from a Marijuana Dispensary which has just opened in oakland, california. People have been lining up since 4am and b have been expecting this for a long time but it is a Long Time Coming for lots of people here. They have been waiting, some people are entire adult lace for this. The brothers who started the shop have spent their entire adult life advocating and fighting for legalised the glacial marijuana and today they got to see it with several hundred people shoot out the door and no several hundred people buying it. They will now be paying taxes on that, you can only buy if youre 21 or older and not all dispensaries will be allowed to sell Recreational Marijuana, only those that are licensed, so far in california just eat a few dozen have been licensed and here in Francisco Bay area only certain areas are selling Recreational Marijuana and even San Francisco is selling the product. That might not even San Francisco. California led the way on this, in 1996 it was very fast to legalise medicinal marijuana. The problem for some people, Recreational Use, they say they have got worries about people using it and driving while under the influence. That is right, that is a big question because other states have a key hc limit, the colorado but that is not the case in california thc limit. If our Law Enforcement officer pulls you over and see signs officer pulls you over and see signs of impairment they can give you a ticket there is no thc limit to see you have this much in your blood so you have this much in your blood so you get a ticket, that is not the case of that is questions about how much you can smoke before you get behind the wheel, what if you smoke yesterday of the day before . So these are the questions still being worked out here in california. Do you think there is potential for there to be a huge new industry as a result of this change . Absolutely. It is setting up to be a multibillion dollar industry. The prices for marijuana are already going up, not just prices for marijuana are already going up, notjust because of taxis but demand is going up, just this morning we saw several hundred people lining up at the single dispensary. There are several dozen throughout the state allowed to sell Recreational Marijuana but hundreds that are waiting to get the license from the state. There is no telling just yet how many dispensaries will be selling both the medical marijuana and Recreational Marijuana but what we seen here in auckland is the demand is very high and people are willing to spend a premium price for the product what we have seen this year in oakland. Still to come, why china does not want your waste any more. The most ambitious financial or political change ever attempted has got under way with the introduction of the euro. Today we will use money we picked up in holland and use it in belgium. George harrison, the former beatle, is recovering in hospital after being stabbed at his home. The 30 year old man from liverpool is being interviewed by police on suspicion of attempted murder. I think it was good. Just a good . No, fantastic. The latest headlines. As Anti Government protests continue for a fifth day in iran, Police Say One of their officers has been shot dead in the central city of najafabad. North koreas leader kimjong un has issued a defiant new year message warning that hes always within reach of the Nuclear Button. China has introduced new restrictions on the import of foreign waste, much of it dirty or hazardous. The country imports large amounts of waste plastic and paper every year from europe, japan and the United States. Its estimated that china accepted 51 percent of global plastic scrap imports in 2016. But the new ban, ordered by the beijing government, is about to stop most of that and it could have a Significant Impact on recycling industry worldwide. Robin brant reports from shanghai. China has been recycling for decades. He has made a living out of bashing, breaking up, and disassembling. Hes been doing it for five years. Its hard work, he tells me. Tiring. But hes not a green warrior. He does it because theres money in it. China needs the raw materials, so much so that Chinese Workers have been sorting through your waste shipped in from abroad. But the government is stopping that. China has long been the destination of much of the worlds waste. It has imported 7. 3 Million Tonnes of plastic alone in 2016. The uk sends 1200 tonnes of it to china every day. But most of that is ending, and here is why. China has become a much richer but much dirtier country. Its blighted now by home made pollution and contamination on a vast scale. The government claims some foreign waste is dangerous and the last thing this country needs is even more of that. Translation china is putting the onus back on all of the waste exporting countries. You need to show the responsibility of disposing your own waste and your own sources of pollution. The ban presents a problem for china, though, because it still needs the cardboard, the paper, the high end clean polystyrene like this which is easy to ship here, easy to turn into something to sell, and sometimes selling it back to the country it came from. Somewhere in there are polystyrene fish boxes. From grimsby. This business on the outskirts of shanghai ships them, chips them, heats them, and turns them into this. Billions of tiny plastic pellets. Because it recycles them into skirting boards and picture frames. Some of them heading your way. Chinas ban means the boss will now have a problem with his supply. Just keeping the factory running, we need about 50,000 tonnes of recycled plastics. Chinas recycling will not be enough. The tough new restrictions on foreign waste will hurt some businesses here, but the governments view here is, tough. Delivering a cleaner china is paramount for the communist party politicians. A green revolution, you might call it. Robin brant, bbc news, shanghai.
