summit. more than 50 are attending, but not russia's vladimir putin. the kremlin skipped the talks saying the summits achieved non-pr liferation purposes. xi jinping is there and discussed the nuclear programme. he discussed implementing resolutions against pyongyang. british prime minister david cameron announced he wants to make medicine instead of missiles. under a plan they'll send weapons grade uranium to the u.s. in exchange for radioactive isotopes used to treat cancer patients. we have this report. >> reporter: pyongyang has been known for its rhetoric. the latest propaganda was the over the top video posted on the website. it featured an animated depiction of a trike on

washington's mall. >> a decade ago, such war talk could be dismissed as bluster. now the claims of the leader were developing a miniaturized nuclear warhead and a mobile intercontinental mills im, though unverified must be tape seriously. before the summit president obama healed talks with the leaders of south korea and japan, the two allies to the north. >> it's not surprising that one of the ponics on our minds is the issue of north korea. and we are united in our efforts to deter and defend against north korean provocation. >> today's meeting led to discussions on what the countries can do together. altering the misguided calculus.

>> later they met separately with the president of china. thought to have the most influence with north korea. she called coordination and said both countries are committed to the denuclearization of the korean peninsula. penal, even though the north boasts of an underground nuclear test, it was deemed by the u.s. as an unsuccessful total. the north's technology and capabilities are improving. the top general says it is vastly contemplating the war planes. >> today you have to factor in ballistic missiles, cyber capabilities. >> in addition to the traditional threat confronted on the peninsula. >> russia did not take part in the nuclear summit.

pushing the u.s. agenda. ukraine's president says russia is planning on putting nuclear weapons in the disputed territory. it claims crimea of hits own and has no intention of discussing what it does. >> it's focussed on weapons. but an important aspect is the spread of radioactive material. al jazeera's tarek bazely explains. >> reporter: more than 440 million tonnes of cargo passed through the port of rotterdam making it the largest in europe. with every shipping container and shipment of scrap metal comes a potential for dangerous nuclear materials to be brought in or exported. >> these are sources coming from all over the world. they are coming from a band of hospitals and things like that. sometimes they have steel,

tubing, pipes, and i know that they have had a case where he had some small types that were contaminated with enriched uranium. >> radiation senses in the core of the crane sound the alert if anything suspicious is found. it's isolated and passed to government scientists. containers are checked as they are driven through the port. 150 shipments are found to have unusual levels of radiation. >> when suspicious nuclear material is found in the netherlands, it's brought to a government lab. samples are xan and analysed to unts what it is, and whether it poses a threat. fines include iranian issues, and an unused fuel pallet from germany. importers are unaware that cargo is contaminated and blames

suppliers for not checking the safety of materials. they are only finding a fracture of the material transported and admits some of it could be more dangerous. >> the material discovered being out of regulatory controls and intercepted is most likely not all the material which is around that, what we see is the tip of the iceberg. we don't know how big assist. >> low-level material, such as those found pose a threat to public health. if they were used as part of a so-called dirty bomb. of greater concern is highly radioactive fuel and material. >> it's acting upon opportunities. it's so important that you secure it. that they don't have an easy

opportunity to obtain the material. back at the port. the endless job of unloading scrap metal. it's here, rather than the international summit. the hard work of stopping the transportation of potentially dangerous nuclear materials is being done to discuss the nuclear threat and the age of terrorism. i'm joined by jim wall rsh frome m.i.t. programme. and he travelled to iran and korea. let's work our way through the nuclear threat. the biggest is a weapon in the hands of the terrorist group. the countries of the former soviet union and pakistan are the most serious concerns. how secure are the weapons? >> they are more secure than six years ago when we started the process. unfortunately, i fear, antonio. that the process will probably be the last summit.

which is unfortunate, because there's a lot of work left to do. you point out russia is not here. vladimir putin is saying everything it chocolate and roses in russia. that is not true. there's more nuclear material in russia and the united states than all the other countries, and russia faces changes. seven six years later. >> and could those weapons end up in the wrong hands? >> i don't think it's so much the weapons, russia's nuclear weapons, as it is the material to make the weapons, the highly enriched uranium and plut opium. that is what people are concerned about. plutonium is a dirty substance, non-state actors, terrorists would poison themselves. >> too quickly to use it. >> exactly. but highly enrichment uranium is not that radioactive, but is power. and they can produce a nuclear

device. >> another issue is bad state actors that could have nukes. here we are talking now north korea, because we believe iran doesn't have them and is not going there. president obama said he and chinese president xi jinping is committed to the denuclearizition aft korean peninsula. >> unfortunately, for understandable reasons. north korea is terrible for china. all the tests and provocations make foreign policy. difficult to undermine the interests. the only thing worse to do the chinese is the provocations. it's a north korea that collapses. that goes rogue. china will be reluctant to squeeze north korea hard enough

that might risk refugees. they would have a nuclear failed state on the boarder. that is more important to them than trying to persuade north korea to give up the nukes. they'd love them to give up the weapons. the priority is to make sure there's not a failed state. we have to make sure there was no nuclear issue. another concern are attacks on nuclear plants. the isil cells may have been looking at that. how secure are the nuclear facilities. >> in the main, they are in good shape. there are scandals and problems, but i would distinguish a nuclear power plant. most designed to withstand earthquakes. and have fences and guards. defense in depth as opposed to soft targets, a knight club in

paris. it would be a bigger change for a non-state actor. there are vulnerabilities. i, for one, am concerned not about the reactor. it has a lot of reinforced concrete. rather the spent field, where they keep the nuclear waste. >> there is that issue, but there's the issue of how much radioactive material there is out there. people that smuggle it. and that can be used for dirty bombs. isil and al-qaeda have expressed an interest in building them. >> it's a serious threat. i'm surprised it hasn't happened yet. listen, the thing to remember about a dirty bomb is it's not a nuclear weapon, it will not destroy new york city. it's a regular explosion that

has the nuclear material strapped to it. that's bad. mostly people can shelter in place, and move two blocks over. and they can adjust to it. that's the concern. the people that would die in a dirty bomb attack. most of them die from a regular explosive, not from radiation. given the problems that isil had with beheadings and other incidents, in terms of generating fear and a lot of attention, i'm afraid they can do that. even though they could kill the people. good to see you. >> the sole surviving suspect in the 1913 paris attacks could be extradited to france. salah abdeslam was extradited. his lawyer said he was willing

to cooperate with french authorities. 130 were killed by isil. belgium police raided a hotel believed to be related to an attack on paris. it's tied to the case of a 328-year-old frenchman -- 32-year-old frenchman. he was targeted with belonging to a group. after explosives, passports and phones were found at the apartment. in southern turkey a car bomb killed 7 police officers, 37 were injured in the blast. in a bus transporting police officers, no one claimed responsibility, the government is blaming kurdish militants a surprise verdict in the hague, a former party leader was committed of war crimes. they are charged with persecution, murder and torture.

international judges found inevidence. >> reporter: the interestings described him has a scandal master, his rhetoric whipping up serbian hatred. they allege he mobilized the militia. to terrorize groups. after after a trial. the verdict not guilty. >> translation: heef was calling for ethnic cleansing of the non-serbs. the majority believes that the prosecution did not have enough in the possibility. that in making the appeal. they were just participating in the war effort by motivating the serb forces. >> at his political headquarters in belgrade supporters cheered the outcome. he, himself, suspected a 25 years sentence. in any case, having been

released from the hague in 2014, he had no intention of returning to the netherlands. >> from the hotel i went to the hague i knew they couldn't prove any of the crimes i was accused of. i disproved the testimonials and formed the documents. to tell you, after i finished my job, i wasn't much interested in the punishment for the verdict. >> in the croatian town, besieged by militia, the view is different, and the verdict in the hague shocking. >> this verdict is shameful for the court. a failure by the hague prosecutors. the man who we know and here about has done the evil and showed no remorse. >> the verdict leaves the international criminal tribunal in a difficult position. accusing prosecutors of, at best, hiding and at worst

distorting the evidence presented to court. >> we will, as an office review carefully the arguments put forward by the chamber in order to determine if we are appealing this decision. >> he is campaigning for the parliamentary elections in serbia, his refusal to recognise in my submission the authority boosted his standing among the ultra nationalists of the the affect of his acquittal may catafalque him higher an israeli soldiers caught op video fatally shooting a palestinian assailant will face manslaughter charges. the palestinian man was on the ground wounded after attacking a solder with a nigh. the israeli shoulder is shown walking over and shooting the man in the head. israelis are condemning the

>> reporter: the report says immigration agents discourage underage migrants and place children in detention centers instead of youth centers. >> these are the tracks that travel from guatemala to united states. it's a long, dangerous route especially from migrants, who encounter many dangers along the way, and also to immigration officials who are supposed to help them. but persecute them. >> immigration officials didn't respond to the request for interview. but the numbers show how few child migrants are playing to protection. 20,000 unaccompanied children enter mexico. only 241 minors applied for protection, 57 were granted the

status. this could be a result of pressure from the u.s. in the first half of 2014. record numbers much youth arrived in the united states. >> we see substantial increases. in particular, along the southern boarder, since the time that the u.s. committed substantial money and also engaged in diplomacy to do that. despite the pressure, young migrants keep coming, taking the chances to escape some of the most violent countries on earth. adam raney, al jazeera. joining us from mexico city is senior counsel to the children's rights division of human rights watch and the author of a report, closed doors, mexico's failure to protect refugees. first, you found that mexican authorities are violating their

own laws by not telling the kids they can seek refugee protection. they are discouraging them. why do you think that's happening? >> it's unclear why it's happening. i think what we have to assume at the very least it's possible that some may not know what the laws and regulations are. that's being generous. >> it's a culture like the way the institution works. the focus is on enforcement. it encourages ate for apprehended people without status. putting them in detention. the idea that they center to take additional steps to identify people who mifght have

asylum seekers claims. it's a bit foreign to their way of working. >> the government issued a statement denying the accusations saying that kids are told their rights. you interviewed dozens of kids, and you found the opposite. >> that's right. i red the statement. it is incredible. not only did our own interviews show without exception there's one exception. kids were not yoffed of their rights. but the high commissioner of refugees, as well as organizations that have done similar studies. really around mexico. these are reports that not only we have received, but are similar, in line with what other groups found. >> what is happening is kids are

not interested because they want to go to the united states. >> i read that too. we have to - there's a couple of things to think about. one is if the questions that immigration are asking is where are you going, and why, of course kids are going to say i want a better future. of course they are going to say i have picked a place where i think that the life will be better, there'll be employment. i can continue my education, this is what kids tell me, who wouldn't want this. if they have family members in a country, they'll choose the country as a destination, the question is why did they leave. and the reason why many left the u.n.h.c.r. said up to half. many left because of intense violence, pervasive gang culture. >> fleeing some of the highest murder rates in the world is what they are fleeing.

>> what about the u.s. role. you found that the detention of children in mexico has sorried since the big influx of minors, is the u.s. pressuring mexico to detain more migrants before they get to the boarder? >> what is apparent by public statements, statements by public officials in terms of stemming the fellow, making sure that we no longer have the same sort of migration that we once saw, statements that go to say things like the southern boarder. the mexican boarder. coupled by cold hard cash. that flow to mexico after mid 2014. the timing of all of this is not a coincidence. mexico stepped up the enforcement resulting in mane

unaccompanied kids apprehended. with little regard for protection. it's a report from human rights watch. >> the u.s. ambassador to the united nations visits with families. what she says about the sex abuse allegations and the impact on victims. south africa's highest court rules the president violated the constitution and could owe the country millions of dollars.

apply for asylum seekers in greece, or apply to the e.u.'s re-election programme which accepted only a few hundred applications in the past six months. for some, time is not on their side. this person has been here for a month. his family lived through conflict and he struggled to find work to feed his family. now he's in a more difficult situation. >> my wife and her younger brother arrived in germany. he is alone now. she has counsel. i want to be with her. >> he is worried that it will take months before immigration officials look into his case. that is why he's sharing his story in the hope those that decide his future may be aware of the situation and make an exception. >> a multi million dollar
