ago, who said i was not going anywhere. >> reporter: instead he is still collecting delegates vowing to take that he calls his political revolution all the way to this summer's democratic presidential nominating convention. it was a big night too for republican front runner donald trump who also defied the wishes of the political establishment picking up wins in the southern state of mississippi and the northern state of michigan which proved his broad appeal is strong among conservative voters >> i think it is the biggest story today. we have democrats coming over, very importantly, we have independents coming over. if i wind and if i get to go against hillary clinton, polls show that i will beat her. >> reporter: in idaho ted cruz came out on top. marco rubio didn't win a stop.

there are questions of whether he will drop out before his home street. >> we're not going to win the florida primary but florida in november and turn this country around. >> reporter: hillary clinton still leads in the democratic race and did pick up another southern state, mississippi, thanks to after win can-american supporters. she thanked her supporters. >> every time you think can capital get any ugliy they find the way and as the rhetoric keeps sinking lower, the stakes in this election keep rising higher. >> reporter: in one week both parties will vote yet again in delegate rich states like ohio, florida and illinois. it could see donald trump cement his front runner status and also give bernie sanders a chance to close the gap on hillary

clinton's lead for the democratic presidential nomination refugees hopes of reaching countries like germany are becoming slimmer. the western bardans route is effectively being shut down. slovenia has introduced new restrictions. serbia announced plans to shut its borders as well. the countries you see as well had already tightened their border controls in response to the spiralling crisis. that that is left thousands of refugees stranded in greece with no path forward. the poor conditions for refugees stranded on the greek macedonian border is causing diseases. 70% of the children are ill with respiratory issues. many refugees only have tents to

protect them from the rain and winter cold and have poor sanitation. disease control experts have been sent by the greek health ministry as a precaution. we speak to the country director of the charity save the children. joining us from beirut. what are the children's most immediate needs and are they being met? >> yes. children, obviously, are going to be suffering from psychosocial trauma as well as being hungry and also from health perspectives. as you mentioned, the respiratory issues are going to be severe can they be met by authorities and aid agencies? >> obviously, access to these children is very, very critical and services have to be

delivered by both humanitarian agencies as well as by the state. the real situation as well is this is not only are these children stuck on borders in europe but also, obviously, children are stuck in besieged areas within syria itself. so the entire situation in these neighbors countries are also going to be under a lot of pressure such as lebanon, turkey, jordan, as these borders close we will see greater and greater pressure on these nations around syria itself speaking borders, we have reports that the balkans route is being shut down. what does this mean for the health and mental well-being fleeing the war in syria? >> if you can imagine, the children are in a situation which has an impact on them. now they're on the move they have no understanding or ability to know where they're going and

that, of course, creates a lot of stress. plus just a general movement of the children will create other situations such as health issues, access to water, food, and stability. it is absolutely critical for children that they have normalcy in their life. the impact on children as they're on the move is going to have a significant long-term affect on those children looking at reports from idomeni, many only have at any particular times to protect them, it's winter t it's cold, charity workers saying 70% of children suffering respiratory conditions. >> the disease outbreak amongst any community that doesn't have access to enough services is real and that's going to be a significant concern. as you say, there isn't sufficient shelter. the children and families are

only travelling with whatever they can carry and some of that is being lost along the way, some of it is being confiscated and some have to be traded for passage. any resources the refugee population travels with is being depleted along the way. whilst charities and humanitarian aid is trying to actually replenish some of that, there's only so much a population can carry with them. there must be proper shelter put in place, especially if the population is having to stay in day singlet location for any period of time, but also the health checks, the access to medicines, the access to sufficient services is going to be critical. with children on the move, one of the other concerns is, of course, normally you would go to a doctor if an adult has a chest infection or something along those lines and they would have continuous care under a medical

practitioner. now what we're seeing is that each time the family moves, each time the child moves, then that health care is interrupted and that's going to protract any form of treatment for those children thank you, ian rogers, for speaking of us a suspected car bomb in somali's capital has killed at least three police officers. it was next to a café near a police building. al-shabab is reported to have claimed responsibility. tell us about this particular attack now we have a claim of responsibility from al-shabab. >> yes. around 7am local time here in mogadishu there was a car explosion in front of the police station. the explosion occurred when

officers turned up for the morning shift. in front of the police station there is a small tea shop. officers go there to grab their morning tea before they head off to work. it seems that was the target. three officers were killed in the blast, and two civilians was wounded. al-shabab claimed responsibility. i have spoken to mogadishu police chief before i came on air and he told me that they have in custody a young man who they suspect to have played a part in this explosion. he also told me that he is seriously wounded and they've taken him to hospital. as you mentioned, al-shabab said they were behind that attack but it was a suicide bomb and they are trying to distance themselves from the person in custody put this in context and tell us why there has been an increase of attacks in mogadishu itself and what does it tell us

about the security situation there. >> the security situation is quite intense in mogadishu and rightly so. we have seen an attacks of al-shabab. al-shabab wants to impose a strik shia law in somalia and they want to overthrow the government here. the african union has played a huge attempt to push al-shabab out of mogadishu. they had a 20% cut in their budget though. it comes at a time when the african union and somali government have a moral and financial issues while al-shabab is trying to use that as a boost of moral for the soldiers. about 50 kilometers south of mogadishu there was a raid by foreign troops on al-shabab

base. what we know is there was a heavy fight between the foreign troops and al-shabab fighters that was in this small town. what we know is there are prisoners at this base but we don't know if there was - if the operation was successful or the reasons behind this attack thank you. a court in japan has ordered the two nuclear reactors should be closed over safety concerns. that ruling comes days before the fifth anniversary of of the fukushima disaster. tell us more about what was behind that particular decision. >> reporter: that's right. here we are nearly five years on to the day from the triple disaster, the earthquake, stumani and-- tsuna mooshgs i

and meltdown of the plant. there was a large amount of public opinion against returning. there is a ruling of this kind of the district court in the neighboring area to this nuclear power plant. there are currently two nuclear power plants which have restarted since new rules were brought that, a total of four reactors. here at this particular one, there were two reactors that were brought on line earlier this year, one in late january and one in late february. the second one of those, reactor number 4, there was a war leak before it was back on line and after this was brought on line it automatically stopped. they're still trying to work out why it happened. so there are safety issues about this plant. this ruling is about a case

brought by the neighboring area within the evacuation/preparation zone. they're concerned that safety measure $haven't been taken, that coolants to go into the power plant to be a similar situation to fukushima, that is a failing and therefore the district court has ruled in their favor. it must be said that the power companies and the government, they're saying the policy is unaltered the utility companies saying they're going to challenge the decision. it is a major setback for a major policy for the government thank you for that. coming up on the program, upping the stakes. north korea's leader says hits country has created miniature warheads.

it's a ticking time bomb. >>do you know what chemicals have been in that tank? >> my big brother didn't wake up the next day. al jazeera america's... >> today they will be arrested. >>they're firing canisters of gas at us. >> we have to get out of here.

welcome back. the top stories on al jazeera. bernie sanders has pulled off an upset victory over front runner hillary clinton in the michigan primary breathing new life into the democratic race for the white house. donald trump has won three more states. slovenia is among three balkan countries which have tightened border controls to stem the flow of refugees and migrants into europe. 14,000 refugees are stranded on the border between greece and macedonia. a court in japan has ordered

that two nuclear reactors should be closed over safety concerns. the ruling comes just days before the fifth anniversary of the fukushima nuclear disaster. north korea leader says hits country has miniaturised nuclear warheads which can be mounted on ballistic missiles. he says it will be a true nuclear deterrent >> reporter: the statements by the leader have been made during a visit by the north korean leader to see work on his country's nuclear program meeting with scientists and technicians. also accompanied by a photograph being carried in the main north korean newspaper showing him with what appears to be the device in question. he has been quoted as saying that his country now has the technology to miniaturise a nuclear war head and put it on top of a ballistic missile.

they're not particularly new claims and treated with scepticism by south korea and u.s. they believe north korea is working on the technology but they're not there yet. north korea does seem to be recycling some of its claims as way of keeping up the stream of rhetoric and now attributing the claim to the leader. this is a time of heightened tensions on the korean peninsula. we have the sanctions imposed by the u.n., unilateral sanctions from south korea and beginning this week military exercises between south korea and u.s. so this does seem to be the latest response to all of that from north korea israeli police have shot dead two palestinian drivers after the men allegedly opened fire on a bus. the incident happened in the remote area of occupied east jerusalem. no-one on board the bus was heard. on tuesday four palestinians

were shot dead by police in separate incidents. one happened in the port city of jaffa where a palestinian killed an american and stabbed eight israelis. he was then shot and killed by israeli police. that incident happened close to the area where the u.s. vice president joe biden was meeting the former president peres. he is also meeting with netanyahu on wednesday. politicians in myanmar are due to choose a new president following decades of military rule and despite victory in last year's election opposition leader aung san suu kyi is unlikely to become the next leader. wayne hay reports from the capital. >> reporter: ever since the national league for democracy party won november's election, the question has been who will be the next president of myanmar. under the constitution the

n.l.d.'s leader aung san suu kyi cannot become the president because there's a clause that states that anyone who has immediate family members who are foreigners cannot take the top job. aung san suu kyi has two sons who are british citizens. since the election we know there have been negotiations betweenment n.l.d. and the military which holds veto power over any constitutional changes. those talks have been around suspending that article of the constitution to allow aung san suu kyi to become president. it seems those talks have failed. speculation centers around a man becoming the president who is not a member of parliament but a member of n.l.d. but is a cloeft confidenta of aung san suu kyi. they will get the person they want because they dominate their upper and lower houses of parliament. aung san suu kyi herself has said that sympathy will be above the president. so it's clear who will still be in charge despite the fact that

it seems she won't be the president at this stage venezuela's opposition party has launched a new complain it get rid of nicholas modura. the opposition is holding rallies to push for the referendum and the movement to end his presidency. they have been under socialist moeft since chavas took office in 1999. the main opposition leader from niger has withdrawn. he came in second place during the first round of voting in february. the incumbent president won more than 48% of the votes. critics say the polls were rigged. serbia has declared a state of emergency in more than a dozen municipalities where flooded rivers of flooded home.

they stopped using glybercide which is in included in this product. this is now center center of the a global cancer scare. many countries are now rethinking the way they grow food. >> it is a poster boy for the use of chemicals in farming. it has been called the safest chemist cam there is. the people supporting in one sense or another say it's safe enough to drink. it would be a dramatic blow to think that chemicals are the way to produce our food. >> reporter: according to research it has now been found in a third of all bread here in the uchl k. it is seen in soy and corn that are fed to cows, much showing up in meat and detected in breast milk. the question is whether it is nfshgs, toxic. is our weeped killer actually

heart conditions. >> it was added to the 2016 prohibited list which took effect this year. it was on a monday are program last year whereby we track substances that might eventually be added to the list. we look for patterns of misuse. we got this message that it was being used to enhance athletics. that's why we add itted to the list. >> reporter: she received support. >> she is ready to take full responsibility. i think that shows a lot of durnlg and heart. she has always showed courage and heart in everyone she has done and this is no different. >> reporter: she will be provisionally suspended on march 12. a decision on her final penalty rests with the international tennis federation. >> we're used to her being such a fighter on court. that's the way she is in her personal life. so i think that we will find that she will fight on after
