minute men vigilantes in theirry ridiculous inturd to hunt down them >> that's an unfair statement to make. >> reporter: there were questionss of character that only clint could answer or shows not to answer. like her decision to use a private email server as secretary of state. it is a choice she has apologised for but still is being investigated by the f.b.i. >> if you get indicted will you continue >> i'm not going to answer that question >> reporter: there were questions of im proprietapropri seemed to plague her that could cost her votes. it is a challenge clinton will have to overcome if ultimately named the presidential nominee

marching from the city to the mangrove forests. they're protesting against a power plant to be built here. they say it will destroy the area. the government says they're necessary to provide power to around one-third of the population. our correspondent is there they are moving 400 kilometers towards the mangrove forest which what organized by a committee, a citizens' platform to protect the area. they want to persuade the government to stop the construction of 1325 megawatt coal-power plant. it is all next to the largest mangrove forest, just barely 14

kilometers away. this is not the first protest. they want to carry on the 400 mile march to pick up people to protest from different towns across the country. the government saying this is not but a disinformation campaign. they have environmental assessment reports that says it will not have any negative impact and the time is the country needs more electric. the need for power and energy is there north korea says it will liquidate south korean assets on its territory an cancel all economic deals. the announcement on north korean state tv was made after seoul imposed further sanctions over pyongyang's missile test >> reporter: this is a further deterioration in the relationship as though it could get any worse. the north koreans have announced that all economic agreements

between north and south will now be invalid and south korean assets in the north will be liquidated. this affects the industrial zone. more than 100 companies have assets in nb employing some 50,000 workers there. this has been closed since last month. with this announcement the north koreans are saying the assets will be seized and liquidated representing several hundred million dollars worth of investment by south korean companies. also affected is the mountain resort. this is again another project just across the border in north korea. a mountain resort set up mainly for south korean to visit the resort. this has been used for reunions of family members separated by the korean war. as long as it still existed it was the hope it would be

reopened at some point in the future. that seams to have gone. this announcement brings to an end all economic cooperation between the two coreys to our coverage of the refugee crisis. five migrants and a baby have tried to reach europe. a speed unit capsized. they were trying to make the crossing. nine others were rescued. with those kinds of tragic deaths it will be top of the agenda for e.u. officials in brussels discussing border closes and will deal into the proposed plan of e.u. and turkey which would see refugees taken back from turkey to greece. this is one situation the ministers will discuss. the route used by refugees via the balkan.

refugees are no longer allowed to enter there more talks involving rival sides in syria's civil war are due to start on monday. ut u.n. special envoy says he is hopeful the discussions will be productive as a fragile ceasefire continues to largely hold. >> reporter: u.n. envoy staffan de mistura says talks have restarted. the only people he has been meeting are diplomats and his colleagues. he is hopeful the syrian government and the main opposition block block will be back in geneva soon >> the focus will be on new governance, constitution an elections. the future elections in 18 months time, both presidential and parliamentarian >> reporter: that was clearly aimed at the opposition's high

goernting committee. it's spokesman told me he was encouraged by that focus. he said the eventual outcome had to be the formation of a new government without bashar al-assad. the opposition still have concerns, though. the cessation of hostilities has been that place for nearly two weeks, but they say violations by the government like this attack are continuing. they also want detainees particularly women an children released, and as the u.n. task force on humanitarian access met in geneva, they have again been complaining about the government not allowing food and medical supplies in. this case backed in part by confirmation from the task force leader when he talked about the besieged areas the u.n. has not reached in recent weeks. >> reporter: which area is besieging the remaining six areas? >> it is very clear that the six

areas - i would say the seven areas where we have not reached are reached six by the government, one by islamic state. >> reporter: one of those areas is derayaa. the opposition believe it has been deliberately starved in the damascus suburbs. it is militarily and symbolically important to the government side lots more news to come for you, including these stories. a special look at how i.s.i.l. may be using prisoners in europe to recruit fighters. plus. >> reporter: i'm in green land where the national football team is hoping that f.i.f.a. will let them come in from the cold. n from the cold.

welcome back. the top stories from al jazeera. democratic presidential hopefuls in the u.s. have locked horns in a debate in florida ahead of next week's primary. immigration reform was the main sticking point. it happened a day after hillary clinton was bean by bernie sanders in the state of michigan. hundreds of protesters have been protesting against plans to built power plants near a heritage forest. greece has told refugees to accept the crossing is now closed and move to proper facilities. thousands are still stranded in

idomeni after a popular route to europe was closed down. one solution is to send refugees back to turkey and this proposal would allow syrians in turkish camps would allow settlement in europe. it has drawn condemnation. >> reporter: leaders from the turkey and the e.u. have come up with a controversial new plan to try and stop the flow of refugees attempting to reach europe. it is a huge problem. let's look at the number. the european union struggled to cope with a million people last year. they made the crossing from turkey into greece more than 3700 people died trying. that hasn't deterred others. in fact the numbers are growing. since january this year more than 140,000 people crossed into europe and it's not peak season. numbers are expected to spike from april as winter becomes spring.

turkey has born the brunt of this crisis taking in more than any other country. that's around 2.7 million people. it spent more than 9 billion dollars trialling to cope. here what e.u. leaders are proposing. under the plan all refugees that make the illegal cross to go greece will be sent back to turkey. it's a one for one deal. for every person forced to return to turkey, an e.u. country will resettle a civilian living in a camp there. as to those sent back, they will be pushed back to the end of the queue. they have offered 3 million in aid but it is half turkey is seeking. it is offering talks on turkey to become a member of the e.u. and offering turks free travel. some influential voice are

already critical. the head of the u.n. refugee agency expressed deep concern at the: amnesty international described as leaders: add to that, save the children. world vision, doctors without borders. the refugee study center all condemning the proposal as an appalling attempt to push the e.u.'s attempts on to another and a likely breach of human rights and international refugee law thousands of those refugees are children fleeing war an persecution across the middle east and they're travelling alone. most are arriving through greece where the asylum system is struggling to support them. >> reporter: these are some of

the tens of thousands of children fleeing their homes for europe. without family to protect them along the route. this house is just one of two temporary shelters for unaccompanied minors on the island of lesbos is their home for now. only the most vulnerable of the children are kept here. the rest are in highly guarded kon fint centers that some call jail. >> mainly when they come here they're happy to have left the jail, to be in a proper house with colors and toys and stuff like this. >> reporter: the children most of who are from afghanistan speak of walking hundreds of kilometers from their homes to the turkish coast, sleeping in the open before joining others to make the crossing to lesbos. the majority of unaccompanied children arriving in greece are slipping through the cracks >> many of them sadly don't want to be identified. they present themselves as adults because they feel that this would slowdown their

journey otherwise or they present someone who they're travelling with as a guardian that isn't necessarily the case. >> reporter: unaccompanied refugee children can apply for asylum here in greece and stay until they're 18 years old. due to a prolonged financial crisis they will not get proper housing and schooling and social support. most of them, therefore, choose to leave for other european countries. they do so under pressure from their parents and smugglers so they can continue their journey northwards. greece has neither the desire nor the funds to keep them here >> if the state wanted to do something to ensure that the children stayed, then they would ensure that the facilities were of a certain quality, ensure that there were social and - well, social and economic reasons for the children to stay, but at this point in time greece is not even in a position to satisfy the needs of its own citizens. >> reporter: aid agencies are

warning that unaccompanied children are at risk of being exploited and abused by road accident traffickers. >> they're doing three things. the first is the trade of organs, the second is slavery and the third is sexual exploitation. >> reporter: the biggest challenge for social workers now is to convince the children to pursue legal options that may take months other than take under take dangerous journeys with smugglers. greece lacks a formal guardianship system france has the highest number of i.s.i.l. recruits in europe. often the young people are being recruited inside the french prison system. al jazeera gained access to one system to see how a controversial program is

tackling that issue gentleman france has prided itself on its secular institutions. it is increasingly having to evaluate its approach to religion. there are questions over why many young muslims are verifying strongly with groups like i.s.i.l. in object 2015 some 1770 french citizens were either inside syria and iraq, on their way there or returning home. that's higher than any other european country. last year i.s.i.l. sympathisers took their fight to the streets of paris carrying out the bloodiest attacks in france in decades. many of the killers and to have developed their hard line views while in prison. that has thrown the spotlight on a program tested in a prisoner.

law makers are paying close attention to religion in jails >> it is important because it is the first prison to have areas reserved for radicalized detainees. that has been the starting point for the other prisons that have also introduced this type of area. >> reporter: this lady is visiting here to see how successful the trial has been so far. there are 42 prisoners identified as radical according to the authorities in this prison and kept away from other inmates. it is getting mixed reviews, including from fellow prisoners. >> translation: you don't think it's a good idea? >> translation: no. we are human beings after all >> reporter: the prison officers union say the government needs to provide more money and staff for any program to work. the plan they say could even be counterproductive. >> translation: the fact that we are grouping them together and allowing them to be together i find that dangerous. what needs to be understood is

that it is a prison for those awaiting trial. once they have been sentenced, they will be sent out to other prisons. >> reporter: for others the real issue is the positive rill edge yous influences in prison. this man dedicated his time to offering religious guide to prisoners. there are only 200 imams working in french prisons and because they're not considered full-time public employees most visit for just a few hours a week. that's despite the fact an estimated 70% of france's prison population is muslim. >> translation: we have a situation wherein mates are left to their own devices and when there is no imam available, either because he is not there much or because there isn't one in the prison, they will instead rely on other inmates who very often have very, very fundamentalist understanding of islam. >> reporter: many are watching to see where the programs like

the one here will have any impact, but with the rise of the far right in france, policies encouraging a more nuanced approach are more likely to receive attention construction of a building is being blamed for the collapse of a building. the property's owner built more floors than they had approval for. it came after heavy rain. the search is on across africa to find and nurture the brightest minds on the continent. a lack of cash shouldn't stop students from achieving their potenti potential. >> reporter: this man sees the world in numbers. he believes everything from the universe to the decisions fisherman take out in the ocean have an equation. he is the son of a pae nut

farmer and an einstein fellow. >> what inspired me about einstein was his ability to work out everything, to have another way of looking at everything, try not to say, okay, there is a universal truth in a sense. >> reporter: this man works at the african institute of mathematical scientists. top academics teach african students who can't afford to go to mit or harvard but are just as bright. this man fwrou up in a remote village in zambia with barely enough to eat. he spent his days stairing at the sky. he now studies cosmology.

>> we will see more and it will come from here. just wait and see. >> reporter: the african academics behind this school have started the next einstein forum. organisers of this forum seek to address what it calls research discrimination. they say there is much african research with plenty of findings for the work-- but the work is often under valued and over looked because it comes from the continent. 17 einstein fellows as well as young researchers from across the continent are sharing their innovations with top policy makers, business leaders and academics. >> it is something the world of aids has totally over looked. one trillion dollars has been spent over the last few decades in aid to africa. almost none of it on generating

expertise in africa to design and implement its own solutions. we've seen the consequence. solutions from outside. >> reporter: being an einstein fellow is an opportunity of being part of something bigger. he hopes his mathematical skills may some day unlock some of the deeper mysteries of this world and its untapped resources there can be few places in the world to play football than green land. getting to a game did be quite a challenge. the national side still has ambitions to one day win full f.i.f.a. membership. >> reporter: conditions here are not the greatest, but it doesn't people trying. the lack of a stadium here is just one of the reasons why the country is being refused

membership of the world governing body f.i.f.a. the man hoping to see that change is this man who fought as a child soldier before being given asylum in denmark at age 14. three decades on he is in the dug out looking out onto a ground that if you visitors will play on. >> when i saw the fich the first time, i thought god, people are playing football here. that is not possible. people will come here to experience greenland but not play football. i wouldn't invite anybody to come here >> reporter: a quick pitch inspection shows why it is not possible. the pitch is full of sharp little stones which means players have to wear thick tights in order not to cut their legss which is why they choose

to take their passion for football inside. green land is going from strength to strength with their teams taking the games by storm. it is crucial for player development given the problems faced by 911 a side league. contested by towns hundreds of miles apart with no roads in between. national defender works in nuuk's harbour preparing boats which is one of the only means of getting to matches. >> translation: in other countries you can take the train, bus or drive yourself. we can't do that here. very often clubs condition come to the green land championships because it is too expensive or the weather is so bad that you can sail. >> reporter: green land is likely to need full independence from denmark before its team can hope to get f.i.f.a. rank making
