collecting delegates state by state. what this is in terms of these results is a victory for those who are sending the anti establishment message that many in the u.s. are simply frustrated with the way the government has working. >> it was the win he was waiting for, the u.s. state of michigan where young democratic voters there overwhelmingly backed presidential candidate bernie sanders. >> i want to take the opportunity to thank you the people of michigan who repudi e repudiated the p nushgs dits that said i was not going anywhere >> reporter: instead he is still collecting delegates vowing to take what he calls his political revolution all the way to this summer's 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. he proved his broad appeal is strong among conservative voters. i think it is the biggest story of politics today. don't forget we have democrats coming over, very importantly, we have independentants coming over. if i went and get to go against hillry. >> reporter: in idam o coming out on top. marco rubio didn't win a state. questions therefore of whether he will drop out before the march 15 vote in his home state. he says no way. >> we are going to win florida in november around turn this around >> reporter: hillary clinton still leads in the race and picked up another southern state thanks to overwhelming support

to african-american welcome. she thanked her supporters. >> every time you think it can't get any uglier they find a way and as the rhetoric keeps sinking lower, the stakes in this election keep rising higher what happens next? >> reporter: if you can believe it, there are more votes happening a week from tuesday, so we're going to go through this all over again, but the stakes will be even heighter for the candidates because that's about candidate rich states where there is so much at play in victory, we're talking about states like ohio, florida, illinois, what it means if he were to cement bernie sanders front runner status, and it could allow bernie sanders if he does pull out a victory in one

of those states, it could mean that he has a clear path towards challenging hillary clinton who right now still has the math and the odds in her favor. she has three times the delegates of bernie sanders but he says the states where he sees a path to the nomination are still yet to come thank you. a suspected car bomb explosion in somalia's capital has killed at least three police officers. the blast was next to a café near a police build. al-shabab is reported to have claimed responsibility following a series of other attacks recently. refugees' hopes of reaching countries like germany are becoming slimmer. the route is shut down, slovenia has introduced new border restrictions. only people who plan to seek asylum or those with clear humanitarian needs will be allowed entry.

that prompted ser i can't to announce plans to shut its borders with macedonia and pull gar i can't doctor doctor bulgaria to anyone without any proper documents. thousands of refugees and migrants have been left stranded in greece with no clear path forward. as the number of options for refugees shrinks, there are question marks over the e.u.'s plan with turkey to ease the crisis. our diplomatic editor james bays has more. >> reporter: the european union has had plans to deal with the refugee crisis before they've all failed. this year alone more than 140,000 people have arrived by sea. e.u. leaders have come up with their new proposal that goes much further than any tried before. for the first time they say those who arrive from turkey will be sent back. its controversial. already the u.n.h.c.r. has

expressed concern and questioned its legality. >> reporter: do you fear that the proposal in its current form is illegal unhumanitarian law? >> yes. it is prohibited under the convention human rights on an agreement to blanket return of any foreigners to re-entry is not consistent with international law. >> reporter: even tougher criticism of the deal which was negotiated until the early hours of the morning in brussels has come from human rights organizations. >> reporter: it is an extraordinary idea. an idea that might soun good at 1 o'clock in the morning but in the cold light of dra it is fraught with problems. if the e.u.'s idea of taking part in a global responsibility, global sharing of refugee is to make the number of syrian refugees it takes in conditional

on the number of syrians prepared to risk their lives in a boat, then that is decision-making from the heart of a moral aabyss. >> reporter: when the u.n. meanings in a week's time they want clarification about the new plan. there are not potentially legal problems. the e.u. knows the world is watching and pictures of desperate people being forceably removed will be deeply controversial the poor living conditions for refugees stranded on the greek macedonia border is causing sickness. charity workers say 70% of children are ilwith respiratory issues. many refugees only have don'ts to protect them from the rain and winter cold and they have poor sanitation. disease control experts have been sent there as a precaution. save the children's official

describes what his organization has been seeing >> the conditions are deplorable. the situation is really critical. i think this is some of the worst we've seen in a very long time. it is very difficult to imagine that this is europe 2016. we're talking about a facility that was built to hope 4,000 people but now holding 14,000 people. they might have a tent or blanket, but most people are sleeping out in the cold. they're playing in sewerage water. the bathrooms are overflooded. it is a critical situation here. we're seeing more people arrive but the border is only open for a few days letting a couple of hundred people through when thousands of people are arriving on the islands. for every surgeon returned from greece to turkey the e.u. has to

resettle a syrian from turkey to the e.u. which in practice it will that for everyone settled for turkey there will have to be a person risking their life. you have to question the morality of this. we have just thrown out the refugee convention out the window. et e.u. seems more worried about protecting its borders than protecting people. all of this is illegal. people fleeing war through% indication are intimd to an assessment of their personal conditions and then based on that we can decide whether they are entitled to asylum in the company or not human rights groups are considered about how bring the ithe-- 3,000 have been returned to countries. a man arrived by himself as a

child. >> reporter: this man was just 12 when he left afghanistan with his brother. >> we went to iran, turkey. >> reporter: by the age of 13 he had crossed continue incidents to reach britain. his mother's departing words ring in his words >> make sure you don't come back. she thought whatever it is, it might be drown in the sea than blowing up as a intoumer or killed in an eye rang ee attack. >> reporter: his fate was at the mercy of people traffickers and authorities. when he finally got to brant no-one believed his story. he fought to be able to stay. >> you're sending me back to a war zone. when they go back, they will be threatened. they will be the one who will be more risk of becoming radicalized. they will be angry.

>> reporter: figures show that during the past nine years 2748 young people who had sought asylum in britain as unaccompanied children were sent back to war torn countries soon after they turned 18. the vast majority in 2018 were sent back to afghanistan. others were returned to iraq, iran, libya and is syria. >> when they turn to 18, but their life ends in many ways. it is shocking to see the numbers. >> reporter: the u.k. government defense its recording telling us: >> reporter: >> reporter: >> reporter: with the refugee crisis in europe showing no sign of abating, the numbers of

>> "fukushima: a nuclear story," narrated by willem dafoe.

welcome back. the top stories. bernie sanders has pulled off an upset victory over hillary clinton in the michigan primary, breathing new life into the democratic race to the white house. donald trump has won two more states. slovenia 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. many children are falling ill. a suspected car bomb explosion in the somali capital has killed at least three police officers. al-shabab has reported to have claimed responsibility following a series of similar attacks recently. taliban fighters have launched a series of attacks in southern

afghanistan. three gunmen have been killed. north korean leader says his country has miniaturised nuclear warheads which can be mounted on nuclear missiles. >> reporter: statements by the leader have partial apparently been made by a visit by the north korean leader, meeting with scientists an technicians. it is also accompanied by a photograph carried in the main north korean newspaper showing kim with the device in question. he is saying that his country now has the technology to miniaturised war head and put it on top of a nuclear missile. these claims are not clear, but

they come with criticism from south korea and u.s. north korea does seem to be recycling some of its claims as a way of keeping up the stream of rhetoric and now aattributing 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., unlateral sanctions from south korea and beginning this week military exercises between south korea and the u.s. this seems to be the latest response of all of that by north korea four palestinians were shot dead by police on tuesday in separate incidents after allegedly trying to kill israelis. one of the incident was in jaffa where an american was killed who was then shot and killed by police. >> i ran over here to see what

was going on. there was a man on the floor. he received stab wounds here and on his back. i took off my jacket and i put it on his eye and i tried to turn him over a little bit to see if he had received any other wound and put pressure on them an update from jerusalem. >> reporter: these attacks on tuesday are a reminder of the low-level but ongoing violence and an increase in attacks on individuals which really started in earnest last october in occupied east jerusalem, a palestinian on a motorbike fired shots at a member of the israeli police who was seriously wounded. he tried to escape but then shot by a police officer shot him

dead. the border police had killed a 50-year-old palestinian woman within the walls of jerusalem's old city. she had drawn a knife and attempted to stab one of the police officers. a palestinian eyewitness disputed that version of events, but all of this latest violence really comes against a backdrop of the israeli palestinian peace process going absolutely nowhere the attack in the city of jaffa happened close to the area where vice president joe biden was meeting the former prime minister and also the netanyahu on wednesday. the obama administration is facing criticism over whether it has abandoned its efforts to broker a peace deal between israel and the palestinians. a look at u.s. efforts to restart that process.

>> reporter: this was the last time john kerry saw the israeli prime minister and president which did not come out of the meetings in late november, a resumption peace process. the obama administration denies it has given up >> this notion that itwe've giv it up that it is something that feeds to be kick started kon vase this idea that we just thrown up our hands or we did at some point. that's not the way the secretary looks at this. >> reporter: in the face of more immediate crises, i.s.i.l., syria, north korea, some experts say president obama has given up on the peace process. there haven't been talks between top negotiators in several years. then secretary of state hillary clinton launched the administration's first effort in 2010. john kerry tried again in 2013.

both attempts fell apart and a new effort has not been made. obama's former mid-east adviser wrote that the lack of u.s. focus is putting the vision of a two-state solution at risk, especially in light of the israeli's government's continued building of settlement in the occupied west bank and attacks on israelis and palestinians. the solution, try to reach another deal but don't put pressure on israelis to stop settlement building right now. americans for peace now opposes settlement construction calls ross's idea laughable >> what this is saying is we want to fundamentally change the entire concept of israeli policy and peace. we want to erase all of the understandings since 1993 and we will start over based on the

situation today. we will decree that and the palestinians are just going to have to accept it. >> reporter: in the end some officials say until they see a willingness to return to talks, all they can do is wait for the first time since the war began in yemen last month, a houthi delegation is in vaush for talks at ending the fighting. they're taking place as yemen's battling economy is struggling to deal with the blockade and rising prices. >> reporter: supermarkets appear well stocked, but what they're selling is becoming too expensive for many. a year long conflict between houthi fighters backed by iran and a saudi arabia led coalition of arab countries is hitting the economy hard >> translation: you can't find u.s. dollars in the bank and the black market has seen it go up.

the people are the victims. the economic blockade should be lifted. the committee has completely collapseed. >> reporter: this area has been taken over by houthi forces. the saudi-led coalition has put up blockades to force the houthis out. >> translation: the entry of goods through border posts has become very difficult which is why they're slow to reach the consumer. >> reporter: a thriving black market for i will products has duplicated the price of petrol to a dollar a letter. a significant sum in the arab world's poorest country. there are reports of a lull in fighting. citizens say the latest vau decoalition air strike was about a week ago-- saudi coalition the w.h.o. says sexual transfer of the zika virus is more common than previously

thought. there was increasing evidence that a spike in disturbing birth defects was caused by zika. most of the zika cases have been reported in south america. >> reporter: venezuela's party has launched a campaign to oust president maduro. the country has been under 17 years of socialist leadership since the late chavas took office in 1999. the main opposition coalition in niger's presidential election is withdrawing from a run-off vote which was supposed to happen later this month. the jailed open silgs leader came in second place during the first round of voting in february. the incumbent president won more than 48% of that vote. critics say that poll was

rigged. politicianss in myanmar are due to choose a new president following decades of military rule. despite victory in last year's election, aung san suu kyi is likely to become the next leader. >> reporter: ever since the 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 can not become the president because there's a clause that states anyone who has immediate family members who are foreigners cannot take the top job. she has two sons who have british citizenship. there have been negotiations between the n.l.d. and the military. talks centred around setting aside or suspending that article of the constitution to allow aung san suu kyi to become president. it seems those talks have failed

and much speculation centers around a man called tin chaw becoming a president. he is a member of the n.l.d. and is a close confidente of aung san suu kyi. the n.l.d. will still bet get the person they want because they dominate the upper and lower houses of parliament. aung san suu kyi said she will be above the present. so it is clear who will be in charge the major highways in nigeria's north east have been closed for years following attacks by boko haram. that caused significant damage to trade businesses as well as livelihoods. now multinational forces have managed to clear the area and revive its economy. >> reporter: cashing in on the relative peace here. once a headquarters for boko

haram. deals from electric far away as car, they're crossing into the border city. this was not possible six months ago. this group lost 1500 head of cattle the day boko haram occupiedment area. he escaped before the army took back the city. they came in the morning chuting when the mark was busiest. they drove away more than 1700 cattle. some have not recovered from their losses. the market is bus yr than before the attack. >> reporter: more than 2000 heads of cattle pass through here every week. traders are picking up supplies for neighboring countries and beyond. more than a year after boko haram's attacks the central market is bubbling with activity. when the city was captured, the

market was attacked, looted and set on fire. today business is growing and traders from neighboring countries are coming back. >> reporter: although much of the city have recovered, there are reminders of the one-month occupation, and outside of the city. those who fled are bait. this 80-year-old refused to flee. when some of his members were killed and the rest left the town. >> reporter: life was difficult then. at some point i was surviving on tea. there was little help because laf was a big struggle, but now my family is back and i'm glad. >> reporter: at the front line against boko haram is less than 50 kilometers from here. most people will know it will take another attack to shut out the new found confidence in the city a total solar eclipse cast parts of south-east asia into
