this is deja vu news live from berlin tensions over migration turned violent in the german city of cabinet's several people are injured after a second day of protests the german government condemns the un russe and warns it will not tolerate mob violence against foreigners also on the show. our killer robots the future of warfare experts from around the world are meeting in switzerland to discuss how to deal with weapons that can fight wars and kill humans all on their own. and when drinking tea is one of the few pleasures left in life we

visit a family in iran already hard hit by a bad economy and now struggling under u.s. sanctions. i'm brian thomas a very warm welcome to the show in the german city of camden police are investigating a number of people after a night that saw several thousand taking to the streets to protest immigration they were met by about a thousand counter-demonstrators the two sides kept apart by hundreds of riot police concerns over further violence has now prompted germany's interior minister to provide additional police support to the eastern state of saxony. clients are up today again on the streets of chemists on monday as far right demonstrators faced off with counter protesters. a call by a right wing group attracted as many as two thousand far right protesters. and

around one thousand counter-demonstrators leaving the police scrambling to keep the two sides apart the protests on monday and sunday were sparked by the death early sunday morning of a thirty five year old man allegedly at the hands of two migrants from iraq in syria they have been arrested and are in police custody authorities have given very little information on the altar cation that led to the stabbing but that doesn't stop the far right demonstrators from demanding retribution. by god auslander else foreigners get out of our city they chant social media posts include videos depicting what amounts to vigilante attacks on migrants. you know what. i'm amongst the demonstrators on monday citizens of chemists who declare they have nothing to do with neo nazis but are simply there to express their anger at

the situation in their city. the kids who go on every evening this trouble encounters between groups but i don't want to say it's only the foreigners who covered this plenty of trouble makers are more focused you want to go out you can't go into the city without being scared of what might happen if i wouldn't call myself part of the mob and i don't want anybody calling me that just because i'm standing here. what happening cemex is being closely followed on a national level police and politicians are warning against vigilante justice after two days of violence in chemist's the city remains on edge. all short while ago the german chancellor address the events in chemistry in a press conference with her counterpart on average. that's good enough because what we saw there has no place in a country where the rule of law prevails and we have video footage of people being hunted down and herded together hatred on the streets. i can't stress enough that

this is incompatible with the rule of law that's going to pick just again. very incompatible with the rule of law let's bring our our chief political correspondent on the crane for more on this there have been calls for all more forceful response to the far right violence in comments how would you gauge the chancellor's response today well she had very strong words to say and she had her spokesman express similar thoughts yesterday in the weekly press conference of the federal government in both cases absolutely condemning vigilante justice and saying that even an attack and a death like the one that occurred in the night from saturday to sunday cannot be taken as any kind of reason for the sort of violence that we have seen in the last couple of days in the eastern city of camden and certainly also not for the kind of

hunting down of people who were appear to be migrants such as has also occurred so yes it was a strong statement one person that many people had been looking to hear from was the interior minister who in fact had had little to say about the events in cabinets until today he has also now spoken out but the key thing is what kind of actions will follow these words because the fact is and we heard it today from the head of the the union for policemen the fact is that continuing cutbacks in the security services continuing cutbacks in personnel with the police have left then the german cities and regions short staffed and the president of that police union made it very clear today he said you know where people feel that the cities are not in

a position to control what happens on the streets we see a rise in risk in the risk of the justice. the real question is will we see federal and local politicians take action both to to preserve the order but also to do the kind of education the kind of social media work that is needed to stop the very forces that are writing these attacks and that's that's that's a long term plan and you know in the interim to get the situation under control could we see federal police being deployed to come yes or elsewhere in saxony to help out state police briefly well in his own statement the interior minister did make an offer to send federal officers to kemet local officials there today in their own statements admitted that they had underestimated the situation they said that we're seeing a lot of far right demonstrators coming from other regions in very very well organized protests and that indeed they did need to greatly expand the police

presence so they may well wind up taking the interior minister's offer but beyond that as i say crucial to see what other efforts will follow to get the situation under control and to prevent further incitement and organization of such actions ok melinda crying for us our chief political correspondent thanks very much more. but you know part of the fan base of the chemist's football club played a major role in organizing this right wing violence that we saw in some of the protests to tom going to sports has been tracking germany's football fan scene including that in kenya sense for being with us today tom what would you say. when you look at the situation that you've been following how was it possible that a part of the fanbase managed to organize such a large group of people so quickly in cannes that's well i mean the football club any football club offers you know they're all football fans it's for

a group of belonging to or attaching themselves to any football club it's quite easy to reach a large audience quite quickly especially over social media now particularly relevant was in this case a facebook post by an all to a group called chaotic candidates on sunday evening let's have a look at what they wrote our city our rules we call them fans and sympathises to come and join us on the streets let's show you who's in charge in our city on the loyalty passion now back is fairly standard fare when it comes to a group like how is it commits you are known to constitutional authorities in saxony they regard this group as an extreme far right group and we know that. a demonstration yesterday. observers positively identified right wing hooligans from bavaria dresden and. is particularly relevant because in the francine in corpus there are very close links to the fan scene in chemist's. ok you mentioned

the eastern cities the eastern region how deep a problem is this in german football. i mean anybody who watches football especially if it was stadiums in lower leagues in the east is likely at some point to encounter this as i said chaotic chemist is known to the constitutional authorities in saxony. there. groups in this scene commits f.c. one called the n s boys who are also known to the constitutional authorities this is in pictures here that we're seeing of the n.s.t. always displaying is a picture taken directly from the youth in the nineteen thirty s. now what's also bit of it here you see the game that this was actually taken. wasn't even a game of the chemist's f.c. and these are fans from chemists they join the group with whom they're linked in corpus. it's estimated that in chemists alone there are between one hundred fifteen two hundred football fans who are regarded by the authorities as extremely right

wing ok briefly if you could dump what can authorities do to get on top of this particular situation what it takes a lot of engagement from the clubs that's very difficult because these people are powerful on the stands and the situation has been allowed to rise a culture has been allowed to develop in certain german football stadiums where these people feel. like they have the freedom to displace things you know like those nazi insignia that we wouldn't necessarily see them doing outside of those things so as evidenced in vulnerability exactly exactly and i mean a free hand basically and that is a culture change that's going to take a long time to reverse thanks so much for looking into this. now for some of the other stories making the news at this hour japan has warned that north korea still poses a threat to its national security that despite a pledge to denuclearize japan's defense minister says that north korea still has several hundred missiles capable of reaching japan even after the summit between kim jong un and president of. the un human rights council says all sides in the

yemen conflict may have committed war crimes report by three experts says children have been the most vulnerable in this conflict saudi arabia supporting the yemeni government against who the rebels who are backed by iran. france's popular environment minister nicholas low has resigned live on radio. without telling president before hand. picked a low as an icon of the green movement but he repeatedly clashed with his cabinet colleagues he felt they were too weak on environmental issues. but government experts from around the world are meeting in geneva to discuss the future of so-called autonomous weapons systems also dubbed killer robots these systems can operate and kill without human guidance critics are calling for this new generation of weaponry to be banned globally before it goes into mass production. germany's armed forces already make use of semi autonomous weapons base add offenses to can

seek out targets on its own. for now soldiers still have to give the order to fire but fully autonomous weapons are being developed they can select and attack targets without humans at the controls. their highly controversial supporters say the new weapons are needed in modern warfare and will help people make ethically responsible decisions. warfare is becoming so fast right now that human beings are not capable of making intelligent informed decisions like they could in the past others have voiced concerns that autonomous weapons could diminish human responsibility in war we don't want to have happen is robotic system isn't out there causes some kind of mash casualty event and we know humans have all. these activists in berlin are protesting against autonomous weapons they want the german government to campaign for them to be banned worldwide.

what's dangerous about artificial intelligence and robotics is that they're altogether removed from human decision making about good and evil about what's useful for people and what's not about a concrete situation human intelligence is still required for that. an international ban on autonomous weapons systems would only be possible with the unanimous support of the united nations but with the u.s. and russia both opposed that's highly unlikely. so could we see a mass casualty event without human responsibility in the future toby was joins us now is a professor of artificial intelligence at the university of new south wales thanks for being with us. have killer robots already been rolled out on battlefields i mean what kind of threat level are we looking at right now. well there are

a prototype weapons development but there are very few if any actually operational i mean you could. tell them a century in the d.m.z. between north and south korea is an autonomous weapon however a very basic thought in a very few number of years we. pose potentially large numbers of these weapons operational that's something we like many of my colleagues that was michael. ok you've described these weapon systems as the new weapons of mass destruction can autonomous systems really wield that much power or are they like nuclear weapons and chemical weapons. well they are like nuclear weapons again to weapons is that they have the potential to write large numbers of people they allow us to industrialize to work on a scale that only if you have the weapons all things like it weapons and weapons and they had one important characteristic they will be much cheaper than you can when it's much more widely available much. that's why it is. the

opportunity now to try and take action before they do become that widely available ok you're talking about taking action but can you even keep these types of weapons out of the hands of non-state actors you know rich individuals for example. yes i think you can add to the good example there is chemical weapons we've decided that it's morally unacceptable to use chemical weapons out of arms. and that's what we need to achieve a we need to decide collectively globally is normally an extent. decided it's one who dies and then manufacture them and then they won't be widely available and when they do occasionally get used like chemical weapons do occasionally use the world to condemn them as they do with chemical weapons that's the way the arms regulation works by deciding what is morally acceptable the rest flows from there ok briefly if you could are you hopeful that we could soon have

a ban internationally. i'm hopeful that we will eventually decide because like chemical weapons we would decide it's morally repugnant i am worried that we will have to see the horrors such will be forced before we have the courage the conviction to do so if that's not the case toby walsh professor of artificial intelligence at the university of new thousand southwell thanks very much for being with us. washington has told u.n. judges that they have no jurisdiction over u.s. sanctions against iran this comes a day after hearings began at the international court of justice where raney and lawyers are demanding that the u.n. court lift the american sanctions the u.s. argues that it has a sovereign right to protect its national security from what it describes as around nuclear threats. and it televised speech arraigning president hassan rouhani blamed quote a bunch of and here remains in the white house for conspiring against his country

and he assured citizens that iran would overcome and see challenges more giving. more which is really not the lawyer going to be on here we needn't go there in the white horse to. call his to feed the white house will not be happy if the. middle of this horse oh . well meanwhile every day a rainy ends are finding it difficult to cope with the worsening economic situation not everyone blames the u.s. sanctions though many say iran's economic problems are homegrown. makes t. you couldn't tell that her family are really struggling. her husband does not earn enough to make ends meet. they can afford new clothes for their daughter or even enough food. so i am member to know if i have to go to bed hungry so be it but not

my child our situation is really tough in that respect we're lucky to have just one child i can't imagine how families with lots of children get by. we're already living on the edge i have to pay the rent every month we have a bank loan i'm very worried. says he could lose his job any day he works for a company that makes cardboard boxes it's bus. he had big plans he wanted to expand but the currency crisis put paid to that the lira resumed its with decline in part because of renewed u.s. sanctions the price of raw materials soared his customers can no longer pay him. this machine has been standing idle for almost three months we're producing much less than we used to when customers would order ten thousand cutters we use this big machine now out of the order of five hundred we use the small machine over

there. and. the work force used to number forty now just six. for. over the next few days i shall have to let two or three more go i'm already paying their wages out of my own pocket. says he needs waste paper to make cardboard but the government is now selling it to china in order to earn hard currency his life's work is at risk and he worries about his staff. you know what about young workers what will become of them they have to earn a living the government should focus on them i'm old i'll get by somehow but these workers will soon be out of a job. although fears he might be one of those about to be said he doesn't blame his boss or the americans and their economic sanctions. the reason for our economic problems are to be found here in iran it's not foreign powers and

i think ninety five percent of our problems are homemade. the powers that be should come visit us and see how we live. it would bring tears to their eyes perhaps they would then make better decisions. says that the underlying problems are mismanagement and corruption and that most people who run would agree with him. look at our business news now and a lot of concerns today about italian debt kristoff that's right bryan and an issue that's becoming more pressing italy's economics minister is warning that next year the country could smash through the debt ceiling set by the european union e.u. law demands that new borrowing does not exceed three percent of a country's annual g.d.p. now the euro zone's third largest economy already sits on a huge mountain of debt however italy's populist government has plans to boost spending on social programs while slashing taxes we hear reports say the government is hoping for china and the u.s.

to start buying italian bonds. for more let's bring in our markets man paul brit's of the frankfurt stock exchange or paul italy's debt level or of the stands at over one hundred thirty percent of annual g.d.p. and it could explode next year how worried are investors about such a scenario. well chris of the italian populist government can expect a five star review from investors with this kind of spending lined up if it does follow through there's only two options it has to cover the cost that is either make more money which seems unlikely or cut costs somewhere else neither of those the government has brought any hints. upon and so investors are worried that the italian government is steering towards an economic collision course that does show in the rise of ten year bond yields rise

here meaning it's a bad thing because debt increases. and that's now at the level of three point two one close to the present close to the meltdown that happened in may when the government came in now i mentioned the deal this rising that is making the problem worse because debt is more difficult to get rid of and on top of that the e.c.b. is looking to ease its bond buying program within europe so the main debt by are going to say bye bye now paul italy is reportedly hoping for china or the u.s. to step in and start to tell you bonds what do investors make of the. italian right now and just really isn't you know attractive even though a trump tweeted that he would tell you and the let's say that's very unlikely to tell you the deputy prime minister of course currently being in china lobbying

for investments although he does deny trying to. get china to buy that debt. so there's not really a telling there but it may be if that's the case that the european union can change its mind should that really be the case corporates. in frankfurt keeping his eye on the italian debt crisis paul thank you so much. the united states and mexico have reached a preliminary deal to replace the north american free trade agreement nafta have drawn harsh criticism by u.s. president to donald trump who called it a job killer now with much of the details still to be hammered out already promised that the new deal will help manufacturers and farmers on both sides but the third nafta partner canada has so far not responded to the deal was pressing ottawa to accept new terms on the automotive sector the three countries do more than a trillion dollars worth of trade with each other. up to four hundred

years that's how long it takes for an ordinary piece of plastic to decompose the amount of plastic waste particularly in our oceans is a growing problem many countries have been taking a stance against the use of plastic bags but few have been as rigorous as kenya a fisherman appealed to plastic bags out of the nets and butchers found remains of plastic bottles and pigs and chickens the government reacted production imports sale use of plastic bags always bad. the country market in western iraq is a popular shopping venue it offers nearly everything but no plastic bags which were banned a year ago shoppers can buy colorful reusable bags at each stand instead but they're ten times as expensive pair twenty cents each that's why many people bring their own bags along they've adapted to the change but not everybody agrees with the band

including martin and dinner who sells its. eggs. even though the plan is to help the environment it's bad for my business. i used to sell my yams in plastic bags so they would stay fresh longer. now they dry out quickly like you know i get back get back lazy don't think it's day and yet. nearby there are piles of discarded plastic bags people have simply toss them here illegally. nevertheless officials from kenya's environmental authorities say that back ban has been a great success if your bags are being discarded in public places and few are ending up in fisherman's nets. at the beginning it was a talent available to continue to pack things but we were able to demonstrate over time now over the months that it is possible to carry on your own business and

activities without it and therefore change of behavior that really. that just means people have had to do. that has been positive. violators face a fine of thirty two thousand euros or up to four years in prison so far nobody has been jailed but around a hundred people have been fined. one of the most vocal critics of the ban is the kenya association of manufacturers chairman one hundred good guys the head of a company that makes product labels for the african market he says one hundred seventy companies producing plastic have shut down triggering the loss of sixty thousand jobs the timeframe given was of six months for school short to make investment decisions and for people to reallocate resources and you're not given time to. invest as a face on certainty and this causes tremendous aftershocks

for the manufacturers when a very short time span is given. despite the criticism environmental management authority hopes that kenya sets an example for its neighbors as well this countries beyond africa. and a reminder of the top stories we're following for you are several people are injured after anti immigrant protesters clashed with police and counter protesters in the eastern german city of chemist's on monday the government has condemned the mob wives and experts from around the world are meeting in geneva to discuss the future of autonomous weapons systems killer robots can offer or even kill without human guidance critics are calling for a global back. watching to the news coming to life in berlin thanks so much. for.
