>> this is al jazeera. >> hello, i'm maryam nemazee. this is the news hour live from london. coming up in the next 60 minutes, the u.n. approved it's toughest sanctions against north korea in two decades over recent nuclear tests. >> instead of building walls, we're going to break down barriers. >> i'm going to go after one person, that's hillary clinton. >> donald trump and hillary clinton turn their fire on each other as they pull ahead in the race for the white house. >> felicity barr live in washington, d.c. with special coverage and analysis of those super tuesday results.

we'll explain what they mean in this extraordinary presidential campaign. >> a russian cosmonaut and nasa astronaut return to earth after almost a year on the international space station. >> and i'm farah with all the day's sport. we'll get you the latest from the english premier league title race as tottenham and arsenal try to make ground. >> hello, united nations voted to impose the toughest sanctions on north korea in two decades after it's latest nuclear tests. negotiated by the united states and pyongyang's traditional ally china, they include mandatory inspections of car do leaving and entering of korea by sea or air. a ban on the sale of small arms or any item that could be used

by the armed forces and a banned on exports of coal, iron, gold and rare earth minerals from north korea. 16 individuals and 12 organizations have been added to the sanction' blacklist and an assets freeze on all funds held abroad by the government and ruling party. diplomatic editor james bays reports now from the u.n. >> almost two months after north korea carried out its nuclear test, the u.n. security council gave their response. a knew man must vote in favor of the toughest sanctions resolution yet. >> as the result we have adapted under scores virtually all resources are channeled into it reckless and relentless pursuit of weapons of mass destruction. the north korean government would rather grow its nuclear weapons program than grow it's

own children. >> the fact north korea deified the international community with the launch of a satellite during the negotiations over this resumé have helped persuade the chinese to agree to these new extensive measures. the text of the resolution which is almost 20 pages long, were discussed in numerous meetings between the u.s. and china. some parts clearly directed to the north korean leadership among the luxuries goods band, and equipment like jet skis and also snow mobiles. but despite the agreement on the resolution, china is still strongly opposed to u.s. plans to deploy a high altitude defense system known as thad in south korea. >> all parties concerned should avoid actions that would further aggravate tensions on the grou ground. china opposes thad on the korean

peninsula because such action harms strategic security of china and other countries of the region and goes against the goal of maintaining peace, security and security on the peninsula. >> there are two important questions the provisions of this resolution goes further than before, but will it be properly implemented? and how will the north koreans react in the past when they've been punished by the u.n. security council it's only provoked them to take further action. james bays, al jazeera, the united nations. >> any u.n. on difficult policy against a difficult target

implementing sanctions against north korea is to be welcomed. sets the record straight the u.n. has a very important useful annual report by the so-called panel of experts evaluating the efficiency of the policy that are not compliant and those are important records. the u.n. security council resolution allows many other countries besides the united states, it's allies included to shoulder some of the blame if immediate effect is not within sight. so this is to be welcomed. at the same time i feel new testament security council resolutions against north korea in the past have been somewhat like personal new year's resolutions. the will is strong at first, but then invarybly the will dissipates and the problem grows. over had five strongly worded created harsh sanctions, measures, the obvious question

is there a political will on the part of the important member states to implement these sanctions? >> and of course the most important member states arguebly are the u.s. and china in this. we know that china has always had very close relationship with north korea. is china committed enough to these measures to consistently enforce them? >> over a decent interval say several weeks i think so. already chinese banks have shown conservatism. banks international banks are risk adverse and sensitive to potential financial losses and we've heard reports of china's big banks ceasing all crash transfer with north korean banks. that will be a positive development over the next few weeks. but over the past 25 years or so we know china has had a different agenda strategically. china is very much pleased with

north korea that embarrasses china from time to time, but china enjoys by its tremendous and economic influence over both north korea and south korea, that means that china is most unlikely to really push north korea to the brinks of collapse. so i think china will go on supporting north korea no matter what. >> how might north korea react now? they found ways around sanctions in the past. what will the regime do? >> well, the regime will probably reform to another form of provocation, another missiles test or even a controlled limited attack on south korea. that's been the north korea mode of operation over the past several decades. even in resorting to lethal attacks they have been careful, and they have been always controlled limited attacks. and north korea will link such a

provocation to the latest developments north korea will say these are self defense measures lending a measure of credence to people who vouch for north korea or argue we should not push north korea. however, i think the united states is well boyed to put some real financial pressure on north korea through union lateral sanctions in accordance through uniform sanctions. it dependent on the dollar system. the transactions are still very much dependent on the dollar system and that makes north korea vulnerable to unilateral u.s. financial sanctions. thank you very much. we appreciate your time. more to come, seven men killed in a raid by special forces linked to isil and we're preparing attacks. refugees young and old sleepouts in the cold hoping to cross in

from greece into macedonia. coming up in sport. >> i'm lee wellings at the village run after the olympics moved on it did not stop events from taking place here. >> well turning to the presidential primary race super tuesday has been and gone. it's more super for some candidates than others. let's get more from felicity bar who is in our washington studio. felicity? >> thank you very much, maryam. americans now know it is trump and clinton who are likely to fight it out to become the 45th u.s. president. it is not a done deal as the candidates secure their delegates the let's begin with a look at the two horse race for the democratic nomination.

that is where clinton is pulling away from bernie sanders. to win the party nomination she needs a total of 2,383 delegates. right now five candidates remain in the republican race. ben carson sees, no path forward. the doctor from detroit said he's not out yet. the republican winner needs to amass 1,237 delegates and the latest figure shows trump with 319 of his closest rival is cruz with 226. these are the states in contention over the next few weeks. with most of the focus on the big battlegrounds of florida and ohio 37 that is where the candidates have already started

campaigning. and we're there too. we'll go to kimberly halkett in miami, florida, and john hedron is in columbus. first patty culhane with the fall out from super tuesday. the people of the voting states woke up to the real station that for better or for worse they hoped make it more likely that donald trump will be the republican nominee for president. >> he tells the truth. >> he says what is on people's minds, things that other people are afraid to say. it's blatant honest any. i think its great. >> he harnesses a lot of anger going on in this country for how the country is being run, but i think there is someone better than him to run the country. >> make america great again. remember that. >> in the end rump won seven

states. if that continues he'll march towards the nomination leading the republican party bosses little chance to stop a flag bearer they do not want. >> the party isn't likely to do anything were donald trump were to win a large majority of the delegates. it would be very difficult for them to try to essentially pull the rug out from under him. >> they're trying to keep him from dominating the rest of the contests. now the man who lost the last president election mitt romney said it's an open question whether he'll run or plead with the party with the call anyone but trump. as for the democrats, hillary clinton is continuing her march to the democratic nomination. [singing] but her rival bernie sanders did better than expected, winning four states. he is giving little indication he's ready to bow out. >> what i have said is that this

campaign is not just about electing a president. it is about making a political revolution! [ cheering ] >> super tuesday moved the process along but didn't change any of the dynamics. you up next, big states, florida, ohio, the candidates have two weeks to win there in "n" what could be the deciding factor in who will represent their party to run for president of the united states. patty culhane, al jazeera, washington. >> so as promised we go out to florida and join kimberly halkett in miami. kimberly, no doubt about it, florida is going to be the center of political activity in the next couple of weeks. >> indeed, in fact, the early voting has already started here. marco rubio is one of those to cast his ballots. the contest takes place march 15th, but he's doing that because he's trying to encourage his supporters to do the same. he's really needing to win this

state. it is critical for marco rubio not just because he is the u.s. senator from ngo florida. if he can't win his home state it's inconceivable that he would keep going. but he has only had one victory. needs these delegates. this is a delegate-rich state on the republican and democratic side. it's a winner takes all states. they're 99 delegates at stake, and that's the math that we're doing, counting up the delegates as we heads towards the convention in the summertime with both the republicans and the democrats. on the democratic side this is an very important state for hillary clinton and bernie sanders as well. this is delegate rich for them. 246 delegates at play. proportionate representation on the democratic side meaning that they both could pick up delegates depending on how well they do in this contest.

marco rubio is leading in this state by double digits. it's a challenge for bernie sanders as well in this state. hillary clinton won super tuesday, the sweep of the search states because of the support of african-americans as well as latino voters, older voters, women, you basically just described florida voters when you're talking about who is supporting hillary clinton. that is the problem for bernie sanders. hillary clinton campaigning last night here in her super tuesday and now campaigning in new york city. they're set to kick off a super tuesday post rally in an hour. the campaign is very much in full swing on both sides, and campaigning will be intense over the next few weeks. >> live from florida, thank you so much. let's take you from one crucial

state to another, that is ohio. john hedron is live for us in columbus. explain to us why is ohio so important? >> well, ohio is a bell weather state. since 1964 it has determined the next president of the united states. there is a mix of rural and urban, black and white, industrial, non-industrial. it reflects the country in microcosm. that's why it will hold the election in one state and see the outcome nationally. historically it's always been ohio. they've only missed twice, 1944 and 1960. those were both close races. both about races. it's delegates 66 on the republican side. and with republican and florida as kimberly was just talking

about, on this same day that could be very decisive if trump is upset on those days, and he's leading in those states, that could allow an opponent to block him and that would take this all the way to the convention this summer. right now you've got people like marco rubio and john kasich. they're splitting the votes. so trump is getting something like 30%-40% in some of these races. but he's not getting the majority. if john kasich lost ohio he would probably back out of the race at that point. that would mean a lot of his votes would likely go to a similar candidate in terms of voters, and that is rubio a these moves faster after that. this is a winner take all state, and the republican party deliberately date that. it felt when mitt romney went into the general election, he

was too wounded from the lengthy and bitter campaign. they want to give an advantage to the front runners, so they've left all these winner take all states. now what is happened that has been an advantage for donald trump, who has been the frontrunner and not a favorite of the party. so things could get really interesting in the next couple of weeks. >> absolutely. john hedron live in columbus, ohio, thanks so much. and later in the news hour we'll look at wh donald trump's big win could tear apart the republican party. >> jordan has foiled what is said a potential attack in the country. they said that the sleeper cell was the biggest security operation there in years. jordan has worried about isil on its door step. now it says that the armed group

is trying to put down roots here. officials say that the security operation in the north of jordan stopped planning for a major attack by an isil affiliate. jordan's special forces and police backed by attack helicopters descended on apartment building in jordan's second biggest city. they killed seven suspects. some wearing suicide belts. a jordanian police captain was also killed in the raid. >> this group is misguided and misleading. there are terrorist groups connected to terrorist organizations. they're planning to discorrupt the security of the country and it's people. [ sirens ] >> the operation conditioned into the morning as security forces sealed roads into the area. the crackdown follows the arrest of 13 people a week ago in the same neighborhood. them allegedly linged to the group targeted on tuesday. the camp has been home to palestinian refugees for more than six decades.

jordan's owe initial news agency said said that authorities broke up a cell linked to isil that planned attacks on civilian and military targets destabilizing national security. it's impossible to confirm but the targets were said to be restaurant, government buildings and even schools. >> they chose this area because they could work with more freedom there. it's not a place where authorities expect to find isil followers. >> just 20 kilometers from the syrian border and has more than 100,000 syrian refugees. but those killed in the raid are believed to have been from jordan. supporting jordan for groups like isil existed long before the syrian conflict. the leader of al-qaeda and iraq was from jordan. the armed group attacked hotels in the kingdom in 2005. jordan has closed all but two of its border crossings with syria and only crossing with iraq. there are now almost 20,000

refugees at its eastern border with syria. the government said it needs to make sure that isil fighters are not among them. jordan until now has been relatively stable. but it's a small country with volatile neighbors and pockets of support for isil. hundreds of young jordanians have gone to i can't to fight for the armed group and it's affiliates. the risk of it spreading here is one of jordan's biggest fears. >> now tunisian security forces have killed five heavily armed men near the border with libya. a civilian was also killed by a stray bullet. interior ministry said that they crossed illegally from libya and took refugee from a house in that has seen many arrests in recent weeks. well, the u.n. representative for libya said he has not been able to convince those to go the

way of peace and unity. think warned the u.n. security double that without the formation of an unity government in libya's peace deal the country could soon collapse. >> is there a plan b? >> well, no, this is a plan. and the plan, if you chair the situation three months ago and now, the libyans have made a lot of progress. the agreement was signed. the libyan political agreement, and also the house parliament, they approved, they endorsed the agreement. now it's the second step, and i agree that there are some obstacles now there are those

who wanted to endorse the government, it is now really time to go ahead for the sake of the country. >> so how soon do you think the national unity government can finally be in place? >> well, i abstain from giving time lines. i think it has to be rapidly now. the house of representatives should decide in the next week they always have the sessions on monday. i wrote a letter to the speaker attaching the 100 sittings of those who were there last monday and ask the speak for formalize this decision now that the government in part goes to tripoli. it has to happen relatively fast. >> but they don't seem to share your sense of urgency, do they. we've seen how isil has been able to capitalize on the security in libya.

>> well, i think there are three convincing articles to act. 40% of the hospitals are not working. where 1.3 million are depending on food assistance. and the islamic state. but the way out here the expansion of the islamic state is that the libyans have to organize themselves. it all boils down to having efficient strong government of national unity otherwise the islamic state cannot be fought. it must be the libyan side. i'm afraid the political process is more like a snail, and the military process is much faster. >> what about the military to support isil. >> it must an libyan-led fight. that's why it's important to have the libyan and united libyan army in place as soon as

possible. one cannot doing it with airstrikes alone. this does not work. the libyans have to organize themselves and then if at a later stage they request foreign assistance, then why not. of but it must be ground troops and i encourage all those who are not yet on board in the parliaments but also in the political landscape to take their responsibilities seriously to agree to a formation of national accord, and to have this government of national aoccurred moving into tripoli to do their work. >> thank you very much for taking time to speak to us, representative for libya live from there from new york. >> the white house said there have been reports of artillery fire on civilians their latakia and homs despite the hostilities. but theish humanitarian aid has continued since the cease-fire

came in effect on saturday. they have been distributing supplies south of damascus. thousands of palestinian averages have been under government siege there for more than three years. macedonia has briefly opened its border with greece to let in hundred refugees but more than 10,000 are still stranded. the e.u. has now set aside $767 million to deal with the refugee crisis within its borders and amid warnings of humanitarian disasters. >> they've escaped the violence in their homeland but they're still struggling to find a stable existence that they tried to make their way into central europe. now a potential lifeline as the e.u. announces an emergency financial passage to deal with the largest influx of refugees since the second world war. >> this is to provide basic

necessity including food, shelter, clean water, etc. >> a significant portion will go to greece. it's the main industry point. more than a million have entered the e.u. via greece since 2015. as the balkan countries tighten their borders they struggle to cope. the u.n. is warning of a critical shortage of food, water and medical aid. refugees here sleep anywhere they can as they cross into macedonia. >> there is not enough. this is very small inside, and we see people outside. >> macedonia allowed 170 refugees on wednesday, lit comfort to the thousands still waiting to get through. volunteers tried to help here in the athens food and drink is

being distributed but it's still not enough. >> people bring food, but food is not the problem. we need blankets and services and a place to stay. >> the aid package still needs to be passed by the e.u. parliament and member states. the european commissioner for humanitarian aid says that the root causes of this crisis still need to be addressed. >> obviously this cannot solve our problems. there is no magic for this. now more than ever members of the e.u. need to work hand in hand. >> political cooperation is what is needed as refugees continue to make the arduous journey to europe. >> in northern france police in the port of calais are continue to go demolish the southern part of the refugee camp known as the

jungle. authorities want to move a thousand refugees and migrants from the camp, but activists say the number is closer to 3500. >> i'll tell you how people and their animals are struggling to cope. >> taken into custody for refusing to hand over data. the court order of release. we'll tell you which rookie came of age in the edmonton oilers. that and more coming up in sport. wrap.

>> welcome back. let's take you to the top stories. president obama has welcomed the u.n. decision to impose the toughest sanctions on north korea in 20 years over nuclear tests. security forces say they've killed seven men linked to isil in the city of irbid.

and republican donald trump and his democratic rival hillary clinton have pulled heated in their race to the white house after is it states vote in their primaries on super tuesday. >> thanks so much, maryam. there is still a long way to go in the presidential election, but the reality is sinking in that billionaire donald trump could make it all the way to the white house. we explain how a tv star with no experience is now dominating the u.s. politics. >> it's rare for a businessman to become a celebrity, and rarer for celebrities to become presidential candidates. donald trump has done both. he used the high profile to launch his presidential campaign in 2015 and within hours people were predicting he would quickly disappear. but his opponents have described

him as loud, brash and obnoxious more at home in a carnival than as command center chief. but he has managed to become the most dominant figure and the man most likely to succeed. his support has won in the primaries. he is by far the most talked about politician in the u.s. if not around the world. and. >> it consistently has been a -- a--it's that initial, maybe its curiosity has give way to consistent position. >> touch has been attacked at every stage of the campaign. he has criticized the women, the disabled, latino, american military personnel. >> donald trump is the answer to

a lot of republican questions about what would happen if we were just honest? what if we didn't beat around the bush about race, terrorism. what if we said what we meant? would we be punished for that? would we be isolated or marginalized. according to republican voters, no. there, there are many who are horrified that trump is this close to the nomination. but many say it's the crisis of their own making. >> they all thought that he would do himself in, and they sat back and waited. the reason why they did that was they were afraid of alienating his supporters. touch continues to dominate in the polls and his supporters don't mind his polices are short on detail. they like what he says and how he says it, and they would like to see him saying it from the white house. alan fisher, al jazeera, houston

texas. >> let's talk more about don't trunk and his impacts on the republican party. i'm joined by the republican strategist and white house officialowe official. and jason, let's start with you. is it an exaggeration to say that trump's successes so far are terrifying the republican establishment? >> yes, there is a certain segment that is not only terrified but they're legitimately concerned. and the concern stems from one basic thing, they don't think they can win. this is what this boils down to. if the republican party as a whole actually felt that donald trump could win at a general election, there wouldn't be the concern. his own favorite ability ratings that make people brief that he could possibly cost the senate or house seats. >> you're a good man with

numbers, who are the people who have been voting for touch. they are an initial group. it is not the whole of the united states. >> no, you're right. if you look at exit polls. what is fascinating the key exit poll figure felt betrayed by g.o.p. politicians. so it's fascinating to see just the sense of the numbers that are coming in to these primaries. but what is also fascinating are the issues that are incongruent. going into the trump candidacy was the illegal immigration and unfair trade with china. but overwhelmingly the issues are the economy, national security and government spending, illegal immigration is down 11%, and there is definitely a disconnect in seeing who they're choosing. and then in the exit numbers to see what is driving the issues in this campaign.

>> what happens if trump does get the nomination. how is the wider u.s. politics going to feel about that? are there polls out about how they feel about a president donald trump? >> i look at electability as fools gold. it just disappears on you. but there is always one thing that political scientists look at, there is the decisiveness. there are two terms. is there going to be a negative careover or is it a positive carry over. in many ways if is negative, and that's what jason is talking about, and then in the end they subvert the reaction of negative and then go positive, particularly if the republicans have four supreme court nominees they have to name. >> if republicans don't want

donald trump to represent them, what can he they do to stop him. we know that mitt romney will make a statement. what is he likely to say? >> well, no one knows right now. it seems unlikely that he's going to announce that he's going to run for president. i don't know thatties endorsement would help anybody else. mitt romney is the elder statesman because he's the only other person around not because he carries that much weight with the republican party. i don't know what he can do. the only way to stop donald trump is to change the rules about how many delegates you need, make it a higher number, change the number of states you have to win. it would be some technicality. a that would be the death nail of the republican party if they were to cheat donald trump out of a legitimately-won nomination by changing the rules at the last minute it would be sentencingly saying we don't want to los lose in 2016, we want to lose for the next few

years. >> do you agree with that? >> i do. what would it do to trump, and what would it do to the system that we have in the presidential primaries as opposed to 34 ballots in the midwest in the 1890s where you choose the president. very much with--what is fascinating, too, you look at moderates and conservatives who are abandoning the democratic party. there have been democrats who have been voting. they are not necessarily going to the republican primary, but there is a deflation of turn out compared to the republicans. to some extent if conventioneers try to pull some last-minute changes that will be dire for the political world. >> you look at politics from around the world. you just came back from germany. in what way are we seeing in the u.s. are reflected in other countries around the world, where they're going far left or

far right. the central ground seems to have been lost. >> we see it in france, germany, there is a feeling of many people who 10 or 15 years ago felt that the world was their oyster, that they were being represented, and increasingly they feel disconnected. that's what donald trump represents. it's not just working class white men. that's really too simple. he represents under educated and under employed white men. people who may have a college degree but they work in the service industry. these are people who though are not making as much as they thought they would make. and donald trump has told them i can fix your problems. and the government whether it's republican or democrat, is the reason why you're not successful. >> they are currently not liking the current politicians in the current set up? >> yes, and we see the obama administration driving a number

of factors. when you have the razzmatazz early spring and summer, but the people who attend are like jason is talking about. they're looking for jobs. they're looking to improve their lives, and washington has missed it. they were given an opportunity in 2014 and all these midterm elections when the republicans took back the house and they just feel like washington just does not listen or care, and they're expressing their vote for someone like donald trump from a leadership standpoint particularly on national security as people say, too. >> we have to leave it there, but thank you very much for your analysis. thank you. >> thank you. that is it from washington, d.c. let's take you back to london and rejoin maryam. >> thank you very much, felicity. two civilians and a policeman has died in the attack in india. 19 people were wounded in the

attack, but non-of the diplomats were hurt. it's almost a month since zimbabwe's president robert mugabe. >> if it doesn't rain soon, some animals won't make it. the drought is thought to be linked to the el niño pattern. it is especially harsh in the south of the country. the cattle have become so thin few people want to buy them. farmers have been forced to sell them at give-away prices. they say it's a buyer's market. >> they have give us $500 that normally is 800, 900, and now

they're talking about $150. >> he finds a grassy area to feed his animals but it's not enough. nearly 20,000 cattle have died since the beginning of this year. some rural areas are remote and hard to reach, so it's likely the number is much higher. grazing land is disappearing. a healthy herd of cattle is important for families. it is seen as wealth. they are used for collateral for banks. some farmers hang on to the animals until the absolute last minute. >> if you don't could that, and you have not had the position,

back on the farm, their plan is to grow more maize. it seems his crop has just been no match for what many people are calling the worst drought in recent memory. al jazeera, zimbabwe. >> a brazilian judge has ordered the release of facebook's vice president for atlanta america a day after his arrest for refusing to hand over information to police. he spent 24 hours in this jail after defying a court order demanding data from the company's messaging service to use as evidence in a drug's trial. but the judge said that his detention was unlawful coercion. it comes a week after apple refused to help the fbi to hack into suspects' iphone in the u.s. we have more from rio de janeiro. >> facebook vice president for latin america may have been released from custody, but the

company's troubles are far from over. brazilian police are still in the middle of a drug investigation that they say requires information from what's up, a popular messaging service that is now owned by facebook. but face book says that it operates independently and even if it wasn't to they don't have the information to share because it does not save or store content from its users. this is not the first time that what's up has been in trouble with brazilian police. it was shut down for 4 hours for failing to comply with another court order for information. that's after the ceo intervened and a massive publicout cry. it's the most widely messaging service here with over 100 million users. facebook for its part said that the brazilian authorities have been extreme and disproportionate in their actions. >> joachim el chapo does man said that he wants to be extradited from his mexican

medals here than the world championships that take place over the next few days. it's been an incredible story is a starting a decade ago where they would make sure that the british team would win seven medals and they would follow with another seven on the track in the 2012 olympics. now they'll focus on the tour de france, but more come through and they continue on the experience of the team with stars of mark cavendish. >> i'm not sure if we're allowed to be this close, but do you see this track that cost over $150 million to build. they make use of it because in two years 1.5 million people
