illegally i think our best chance was in 2007. i voted for that bill, bernie sanders voted against it. >> one of the greatest human tragedies of recent years is children came from honduas and i said welcome those children into that country. secretary clinton said send them back. >> reporter: the tone of the debate at times tense as each

candidate tried to score political points knowing in less than a week the state of florida will hold its presidential nominating contest and a large if number of those voters will be latino. >> in 206 he supported indefinite detention for people facing departation and stood with the minute men viglante in their ridiculous absurd efforts to "hunt down"immigrants no. i do not support them and that is a horrific statement, an unfair statement to make. >> reporter: still, there were questions of character in the debate that only clinton could answer. or chose 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 is still being investigated by the f.b.i. if you get indicted will you

run >> v. that's not going to happen. i'm not going to answer that question >> reporter: there are questions of improprietary that seem to plague her over and over again. the issue of trust cost her with voters in michigan and could again in florida and a host of other states voting on tuesday. it is a challenge she will have to overcome if ultimately named the democratic presidential nominee in a general election still to come for you here on al jazeera. juning palestinian shot dead and 30 arrested in the latest wave of violence in israel and the occupied palestinian territories. plus. a ukrainian pilot accused of killing two journalists shows her disdain for a russian court. russian court. dis-d.n.a. dis-d.n.a. ain

can came after bernie sanders won ahead of hillary clinton in michigan. one proposal is to forceably send refugees back to turkey allowing to syrians in turkish camps to be resettled in europe for a one for one basis. the plan has drawn criticism from the u.n. and human rights groups. >> reporter: leaders from turkey and the european union have come up with a controversial plan to stop refugees attempting to reach europe. the european union struggled to cope with the influx of more than a million people last year. most paid the perilous journey across the sea from turkey to greece. more than 3,700 people dried 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 is not even peak season.

numbers are expected to spike from april as winter becomes spring. turkey has born the brunt of this refugee crisis taking in more than any other country. that's about 2.7 million people and it spent more than 9 billion dollars trying to keep. here is what e.u. leaders are proposing. under the plan all refugees that make the illegal krsing to greece will be sent back to turkey. it is a one for one deal. for every person forced to return to turkey, an e.u. country will resettle a syrian living in the refugee camp there. as for those who are sent back, they will be pushed to the back of the queue. in return the e.u. has offered 3 billion dollars in aid for refugees. that's half what turkey is seeking it has offered it revive talks on turkey becoming a member of the e.u. and allow turk visa free travel. it is not a done deal. talks to finalise the agreement are planned for 17 march, but

some influential voices are already fiercely critical. the head of the u.n. refugees agency expressed deep concerns that the blanket return: add to that save the children, world verying, doctors without borders, the refugee study center, all condemning the proposal as an appalling attempt to push the e.u.'s problems onto another and a likely breach of human rights and international refugee law thousands of those refugees are children fleeing war and persecution and they're often travelling alone. most arriving through greece where the stretched asylum system is stretched to support

them. >> reporter: this are some of the tens of thousands of children fleeing their homes for europe without family to protect them along the route. this house just one of two temporary shelters for unaccompanied minors. the meft most vulnerable of the children are kept here. the rest are in confinement centers that some call jail >> mainly when they come here there are 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 unago need children into greece are slipping through the cracks >> they present themselves as

adults because they feel it would slowdown their journey otherwise or they present someone who they're travelling with as a guardian that south korean necessarily the case >> reporter: unaccompanied refugee children can apply for asylum here in greece and stay until they're 18 years old. they will probably 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 neither has 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, they would ensure that there were social and economic reasons for the children to stay, but at this point in time greece is not in a position to satisfy the needs of

its own citizens. >> reporter: aid agencies are now warning that unaccompanied children are at risk of getting exploited and abused by traffickers >> the traffickers are doing three things to minors. 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. greece lacks a guardianship system, another reason for children to take matters into their own hands israeli forces arrested 30 palestinians during overnight raids in response to the latest violence in israel and the occupied palestinian territories. in separate incidents four palestinians were shot dead by

when we heard the shots he was about ten metres away from the soldiers. different soldiers arriving on the scene fired at him on the ground. they left him bleeding for an hour >> reporter: the whole town has gathered here to bury him, just one of so many palestinians who become what they call martyrs to the palestinian cause, but predicting who will be in the next deadly incident or where that will be is virtually impossible. tuesday saw renewed violence not just in the occupied territories but also in israel, including a palestinian youth carrying out several stabbings in jaffa next to tel aviv. he killed one american tourist before being shot dead. on wednesday as he discussed a new military aid package with netanyahu, the u.s. vice president called it a heinous attack >> there can be no justification for this hateful violence. the u.s. stands firmly behind israel's right to defend itself as we are defending ourselves at

this moment as well. that's why we've done more to bolster, help bolster israel's security than any other administration in history. >> reporter: renewed tension and tighter security is called for, but in the absence of meaningful negotiations between israelis and palestinians, few people expect the deaths on either side to end soon the former brazil i don't know president has been charged in a money laundering investigation. prosecutors say say he was detained for questioning last week. he denies all charges. families of 28 missing minors in venezuela are demanding to know what happened to their loved ones. they say the miners were killed by a gang seeking control over a disputed gold claim. the protest is in its fifth day.

longer than anticipated. many were half expecting a verdict on wednesday. that wasn't to be, but there was still plenty of drama in the courtroom. her final statement contained a blistering attack on putin. >> translation: you cannot put all the people in here putin will not be able to keep power at the cost of people's blood. this is against nature, against people, against god and against everything in the world. all i can do is show with my own example that russia with its nationhood and totalitarian regime can be whipped into submission if one is not afraid and if one is not tough >> reporter: to ram home her disdain for the russian courts she did this >> translation: now here is my final statement for you. >> reporter: her mother and sister were there to support the pilot accused of murdering two

russian journalists. when friends and family started singing the ukrainian national anthem, the court was cleared of cameras. a verdict will now be delivered march 21 and 22. prosecutors want a 23-year assistance. her health is a growing concern. she is vowing to continue her dry hunger strike, no food and no water. dead or alive, she says, she will return to ukraine there can be few places in the world where it is more difficult to play football than in greenland. getting to a game or training session or a game can be challenge given the weather and the terrain. >> reporter: conditions for football in greenland are not the greatest, did you about doesn't stop people tryingment

little zones which means players have to wear thick tights not to cut their legss. this is why they take their passion for football inside. [ cheers ] >> reporter: greenland is growing from strength to strength with their teams taking the games by storm. it is crucial for players whom live hundreds of miles apart from no roads in between. this man works in the harbour repairing boats which are 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 cannot come to the greenland championships because it is too expensive or the weather is so bad that you can't sail. >> reporter: greenland is likely to need full independence from denmark because they can get
