levanon struggling economy the government wants to legalize the country's flourishing production but the move is controversial to talk to farmers growing the drug in lebanon's bekaa valley. i'm serious almost on that good to have you with us in the german city of kemet several people have been injured after thousands of far right protesters rallied in the second day of on breast monday evening also saw large leftist counter demonstrations the protests were sparked by the fatal stabbing of a german man but they're being fueled by longstanding tensions over immigration that have polarized german politics. a second day of tension in the city formerly known as calm upstart rightwing protesters rallied beneath

a bust of the father of communism but that message was typical of the contemporary far right. the other quotes was quite the journey for the germans they shout foreigners out. was how it was was. and the journalists got it to. your gut or the press there chanted the german version of fake news. that was that angle followed the lethal stabbing of a german man early sunday morning during the city's annual street festival the killing was attributed to two young men one from iraq one from syria. later on sunday far right protesters took to the streets with overwhelmed police having to draft in reinforcements from out of town. i was happy even to us i saw huge groups of people with a racist mindset it was

a right wing mob they were riding around freely in the city center they were chasing migrants here with too little police presence if they took over the city would you happen to stop i think you know my government spokesperson stephens i but said the events in candidates have no place in a democratic society. we do not accept marauding riots like these nor the hounding of people who look different all come from somewhere else no attempts to spread hate on the streets and hidden by god god god god god have started to get out of our city far right supporters chance in this video shed on twitter after the weekend's violence but as they protested counter demonstrators were determined to send a very different message. to our correspondent charlotte shell some tell us following the very light latest for us from cannes that's charlie good morning to you were at these protests yesterday how intense where they are. morning see

me yes there was another night of violence here on the streets of kenneth last night tensions was simmering throughout the evening that we just paint a vivid picture for you about exactly how the evening unfolded there were hundreds of demonstrators just behind me and then across the street just meters away over on the other side hundreds of counted demonstrators now they were being kept apart by riot police here in the middle that was largely successful through the early part of the evening but then as the fall right protesters started the march there out the city it did appear that some control was lost it was then that stones started to be thrown from both sides fireworks was thrown as well there were reports from police that it. is on the ball right side what seems to be doing the hitlist salute so they really was a lot of tension here on the streets yesterday evening and we know from police that a number of people from both sides were injured in the the scuffles that ensued

there was a lot of criticism that there weren't enough police on the streets on sunday on the first day of protests what was security like last night. yes police on sunday face a lot of criticism for not being prepared for exactly what took place if the numbers of people that gathered on the streets of kenya's in fact that they they they were forced to call in extra resources actual offices to help police the area they were keen not to see or a piece about yesterday so there were a large number of police on the streets fully armed riot police we saw water cannon here as well they were and fired as far as we know they were more to terence to keep the two sides apart to keep control although again it has to be said that there has been further criticism people still think that that just once enough given the huge amount of people who were on the streets last night of these have been dramatic at times violent scenes right in the heart of the city you've been

speaking to locals what have they been telling you. yeah a lot of people keen to stress here that while the number of people into the region they all say well we'll say locals on the streets last night on both nights extremely concerned about what is unfolding in cannes. on the far right side people all grown increasingly concerned about the influx of migrants here in this region those who were on the streets yesterday evening say that they want to express that concern they want to express their opposition to the policy that allowed so many migrants and told me that they want to send a different message to the world they don't want just images of far right protest is big group cost around the world they want it to be clear that germany and ken it's still a welcome that migrants also welcome him and charlotte what's the feeling will these protests and the unrest as well continue in coming. there were

a number of calls yesterday evening from the far right sides of the protests in the coming days as of course something the authorities we watching extremely closely because one thing that we have really seen over the last couple of days is just how quickly huge amounts of protesters from both sides can gather can assemble here and how quickly things can get out of hand say they will be watching in the coming days whether they're all more protests not just here but across the region. following the latest developments for us there in chemists thank you charlotte. now some other stories making headlines around the world u.s. president donald trump and german chancellor angela merkel have agreed in a phone call to seek to improve trade between the u.s. and the european union the white house said the two leaders strongly supported ongoing discussions between washington and brussels to remove barriers to a deeper trading relationship. japan has warned the north korea still poses

a dire threat to its security despite a pledge to denuclearize the korean peninsula japan's defense minister said north korea was still in possession of several hundred missiles capable of reaching japan even after the summit between kim jong un and president in june. united nations investigators have released a damning report on me and mars military calling for the prosecution of its commanders for crimes against humanity they say the military orchestrated a campaign against the country's were hinge of muslims with quote genocidal intent mean marrs a brutal crackdown against began a year ago prompting some seven hundred thousand to flee. the government experts from around the world are meeting in geneva to discuss the future of the so-called autonomous weapons systems also dubbed killer robots these systems can operate and kill without human guidance critics are calling for these controversial weapons to be banned. 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. highly controversial supporters say the new weapons are needed in modern warfare and will help people make ethically responsible decisions. becoming so fast right now that human beings are not capable of making intelligent decisions like they could in the past shouldn't have voiced concerns that autonomous weapons could diminish human responsibility in war we don't want to have happen is robotic systems out there because there's some kind of. 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 a good idea 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. robert frost was an expert on international humanitarian law at the european university focuses on autonomous weapon systems he joins us in our studio good morning to you let's talk about these autonomy weapon systems is a very controversial what do you think of them what are the biggest ethical issues here i think the biggest. ethical issue is can we as a society live with the fact that a machine has taken a decision to kill

a fellow human being it's not either i anymore it is a machine against a human and that's a problem what are the consequences of that oh there are many consequences the ethical perspective as you've just mentioned the legal perspective a political perspective from a legal standpoint there are many questions raised by those devices so give us an idea what this would look like what sectors could they be used in. there is a wide array of sectors in which they could be used and now we're talking about military aspects of the military implications of it and that could be used in a defensive fashion which is easier on an offensive manner which is way more problematic from a legal perspective from a military perspective and regarding collateral damage and the like killer robots roaming the battlefield. is the horror scenario that people talk about and that's what's made them so controversial how widely are they in use today you know what countries are using them. depends on exactly what you take a look at but of course the more developed the richer countries use more

sophisticated weaponry the united states israel and western countries use far more sophisticated weaponry than other countries and. they differentiate between automated and autonomous systems so automated systems are rather widely used and autonomous autonomous systems are not that much used and this is being talked about in geneva right now what role does international law have to play here international football plays a decisive role in determining the galaxy not the usefulness of the ethical implications but international law plays an important role but how effective can it be because we're talking about the biggest military powers in the world that are not necessarily on board with banning autonomy's weapons systems but even they have to stick to the rules that already exists and they cover all weapons that are used even in highly sophisticated weaponry whether or not they're. specific ban for goals of condoms weapon systems remains to be seen if they do not join if those

powerful states do not join a possible treaty. the enforcement is weak and it will not help a lot more to important debate to have robert from from the european university via adreno thank you so much for joining us in a studio thank you. to lebanon which is struggling to write its faltering economy years of regional turmoil including taking in some one and a half million syrian refugees have sent it on a downward spiral of the arab nation has the third highest death rate in the world now as a way to bring in money the government is considering legalizing the growing of cannabis for medical purposes cultivation is currently illegal in lebanon but the industry is thought to be worth hundreds of millions of dollars each year our reporters visited the village of young luna in the bekaa valley where cannabis has been openly grown for decades but as they discovered the locals are skeptical of the government's intentions. alley roams the

fields of his family's cannabis from and have been inspect valley he helps out here from time to time he's nineteen audi is not his real name he says cultivating cannabis isn't a choice for many of the farmers here. they go into this line of business because the state hasn't provided them with jobs. for young men like me or any older farmer who wants to feed his children or any young man who has dreams he wants to build a house get married have start a family or there's nothing else to do but plan cannabis and live off it. his hometown of the moon a is located in the impoverished baalbeck hemel district. for decades cannabis has been grown here illegally. lebanon is one of the world's top five producers of cannabis resin otherwise known as his sheesh. alley his

arm to myself the cannabis trade has been to since the syrian war broke out in two thousand and eleven as lebanese authorities have shifted their attention to other security concerns and he's worried the military might suddenly show up again and destroy the crops something they did for decades. i personally about take up arms if they want to fight my livelihood if they come here with tanks to destroy the crops so that the people will rise up with their weapons that's how they would react if i had to travel. the lebanese government is now looking to legalize cannabis growth for medical purposes in an effort to boost its cash strapped economy but not everyone here supports those plans. and i'm against legalization if it means the state will be supervising the process and i don't want farmers to give their crops to the state and in this state to sell it on to manufacturing companies we are probably legalization only if the farmers have a direct relationship with the manufacturing companies. in twenty twelve

authorities promised farmers here compensation for destroying their crops but sharif says the money never came. he says up to eighty percent of the people here depend on cannabis cultivation to survive without. plugging cannabis now here is a constant. and not a direct action because the state neglected us and our area in general said most of the farmers resorted to cannabis because it was the only thing that guaranteed a return. farmers also say that cannabis is the only crop that can withstand the harsh climate of the bekaa valley. in beirut we meet. this progressive socialist party is one of the supporters of legalization. he says the law would be a first step towards rebuilding the trust between farmers and the state know how we're trying to create a public institution that would manage the other similar to how the tobacco

industry has managed. manufacturers and cultivates tobacco. to keeping a lot of people on their land and has provided them with a decent living. figure mint has not said when the no might come into force that back in your muna time is running out for ali he's due to graduate from school soon and says he might become a full time cannabis fama if he can't find alternatives to senegal now where the country's sand dunes are disappearing but it's not due to climate change sand is a key component of concrete and the demand for the building material and fast growing cities around the world has led to a boom in illegal sand mining in the west african nation now the country's environmental police are fighting back. a stretch of beach by deckard the capital of senegal we don't the road with the environmental police whose job it is to hunt

don't sun thieves. then comes a phone call someone needs to head to the beach the unit is on its way. there they find a horse and cart. under spades but where is the owner. horse and cart are seized they can be reclaimed for in seventy five euros a lot of money in a country in which more than a third of the population lives off less than one euro seventy per day. and i myself feel that by the people here and the living by destroying the environment they don't think about that. it's our job to make them realize if they don't want to we arrest them to protect the environment but that's not the law but. the removal of sundin senegal has a consequence coastal erosion with the natural protective barrier go on the sea can

destroy hoses. here in the northern town of sun louis hundreds of people of already lost their homes. that's why the environmental police are on patrol on the other cart this time. then someone sports the thief. lets go. there he is serious quickly quickly. he will be taken to the police station and could be hit with a heavy fine well that might not be enough to keep him from trying to eke out a living beach. it's something that the police have to live with roger the new says she believes that things will change in the long term. well it's been a dramatic start to the u.s. open in new york with the top women's seed and world number one simona halep

midfielders now the summer. to paragliding now and. spain wrapped up victory in the acro world tour finals with his flight high above lake geneva in switzerland all of the paragliding aerobatics competitors perform some spectacular aerial stunts but it was thirty five year old to impress the judges most almost thirty thousand spectators witnessed the grand finale of this year's world tour. right chris office here with business now we have two big players plotting the future of self driving cars drugs and it's always good when somebody comes along with a big pile of cash now toyota says it's set to invest a half a billion dollars in right here in the service as part of a deal to work together on mass producing self driving vehicles the japanese car giant says technology from the two companies will be used in building hundreds of

special toyota vehicles that produce ride share platform this after we were announced it would expand into bike sharing but made this deal now values will get around seventy two billion dollars it is the world's most valuable startup. times the month. long negotiations seem to be advancing at glacial pace but now the trump administration and mexico have reached a preliminary deal to replace the north american free trade agreement the deal so far known as nafta has drawn harsh criticism by the u.s. president calling it a job killer with much of the details still in need to be hammered out the u.s. president already promised that help manufacturers add farmers on both sides of the border. donald trump welcomed the overhaul of the twenty four year trade pact as he suggested a new name for it if canada is not included. this has to do they used

to call it a nap they were going to call it the united states mexico trade agreement get rid of the name nafta has a bad connotation because united states was hurt very badly by now for many years and now it's a really good deal for both countries u.s. negotiators were pushing for a sunset clause requiring renewal of the deal every five years but the mexican side succeeded in adding a clause that would give it a sixteen year lifespan with the review every six years the two countries also agreed that seventy five percent of a product must be made in the u.s. or mexico to receive tax free status trumps that a trilateral deal with canada is still possible but it's likely that we'll have to agree to new terms on the automotive sector he has put the car industry at the heart of his drive to overhaul the trade pact. with canada relatively soon they want to start they want to negotiate very badly. but one way or the other we have

to deal with it will either be a tariff on course will be a negotiated deal. and frankly a tariff and course is a much easier way to go but perhaps together would be much better for canada and we're looking to help you know we're looking to help our neighbors too we can help our neighbors that's a good thing that. the us mexico and canada do more than a trillion dollars in trade between them annually so all three countries are hoping to finalize a deal. the markets in new york are responding positively to the deal asian stocks are also out this morning now d.w. xian's korda says they'll be watching closely to what happens next with canada well some people call it a bluff that we're seeing from u.s. president that the intention is not bilateral but it lead to real deal and that she tries to put some pressure on canada to join this agreement canada's foreign minister is cutting

a trip short to europe she is expected to be in washington on tuesday and then a new deal. should be done by for rioted that's at least what we're hearing from the white house if that's realistic or not remains to be seen but that's probably the plan to still have some kind of a growing just with a different name and slight changes when it comes to the details. yes quarter of porting from new york they're now u.s. farmers will receive aid from the government to help them all said losses caused by the ongoing trade conflict washington announced that it is setting aside four point seven billion dollars to compensate the agricultural industry soybean farmers who have been worst hit by retaliatory terrorists will receive more than seventy five percent of the aid groups have welcomed the plan but they are still calling for an end to the trade dispute they say the government aid will only keep them going for a few more months. italy's finance minister is in china has denied media reports
