>> i made a huge mistake tennis star admits she failed a drugs test turkey has made a bold proposal to tackle the refugee crisis in europe. ankara is offering to take back refugees stranded in greece in return for more money and the fast-tracking of its push to become a maybe of the e.u. it was put forward in a summit in brussels. >> reporter: finally, at the end of a long day and night the break through they had hoped for. the european union has reached an agreement with turkey that they believe marks the beginning of the end of europe's refugee crisis. >> this is a real game changer. the date of irregular migration to europe are over. our objective is to discourage

illegal immigration to prevent human smugglers, to help people who want to come to europe through encouraging legal migration. >> reporter: the agreement means that in future turkey will take back all those making the perilous and illegal journey across the aegean sea to greece. for every syrian refugee returned one syrian refugee from camps in turkey will be resettled in europe, thus opening a legal route of entree. turkey wanted more from the e.u. in return for its help, more money, the double 3.3 billion dollars pledged already to help syrian refugees on turkish soil, more cast-iron guarantees about the reopening of its e.u. member ship plan and quicker access for turkish citizens to e.u. visas. none of these are promises made by the e.u. here.

they're crucial details and difficult ones yet to be discussed. there are concerns that turkey is using the refugee crisis to forward fast its e.u. bid, anything to advance its case. an agreement in principal only. it is nevertheless an important milestone european leaders outline their strategy while thousands of people stuck in greece have been pleading with macedonia to open its border. the balance can-- balkan state is letting only only a small amount. many have been demanding to be

let through so they can continue their journey. the french president didn't offer them much hope. >> translation: the borders it is greece and macedonia, they will have to understand they will not be able to cross. we have to speed up reloengs and to a certain degree remission. these people need to be supported and provided with aid. greece will be responsible for this and it will be financeed by europe our correspondent is joining us live from the border. as that e.u. summit was taking place in brussels, what was the situation like for refugees? >> reporter: it was a very difficult situation. there was torrenial rains that was here.

you can see here behind me some people are trying to dry their socks and their shoes because of the rain that soaked absolutely everything. this whole camp is submerged with water. people have tried to cover it we're w their rain coasts and blanked, but that meant they stayed cold inside the tent. if you look at this tent the lady was showing me they had put cartons underneath the blanket to try and prevent the water from coming in. it is absolutely soaked. certainly they were looking at the summit in brussels to get some guidelines to what is going to happen to them this morning. they still don't have that answer. yes, there is a deal between turkey and the e.u., but what is not clear is what will happen to the 14 or 15,000 that are here in idomeni and in the larger greece, the other same number that are stranded all around the

country. that is what is not clear. these people are saying going back to turkey after all this is not an option for them the rate at which the refugees have been allowed to cross through into macedonia has not been reduced to a trickle, hasn't it? >> reporter: yes. i would say that from what we've witnessed over the past week or so, the border is symbolically open. you have maybe 10 to go through, to 300, that's below the daily cap that was announced of 500. you have many who are pushed back for several reasons, a set of new restrictions, so you have geographical restrictions, you also have restrictions depending on your stamp, the date of entry into turkey and how long you transitd ed through turkey.

there is no borrower you're going north even if you do get through the border. there are many stranded at the border between northern macedonia and serbia and you have that same situation also further borders while you go further north thank you for that update. two iranian asylum seekers settled in cambodia from an asylum center from australia have returned from their homeland. they returned from nauru. cambodia agreed to take hundreds of asylum seekers over a million dollar deal. we have the director of australian human rights. despite the australian government saying this, it has committed to supporting the

government of cambodia to implement settlement arrangements in cambodia to also encouraging refugees to explore this settlement option. you are still unhappy with this deal. why? >> well, the reality is this has cost the australian government 55 million dollars to send five people to cambodia, three of those people have now left the country. there are only two left. it has been a complete waste of money. i think we knew from the start that cambodia was not equipped as a place to resettle refugees. there were already significant problems with refugees already living in cambodia. so the australian government thought that it could just throw money at the problem and that the problems would go away. i think the reality has been quite different. it's hard for this will the australian government continue to push on with this plan in your opinion. >> they can't send people there unless they volunteer to go

there. as unhappy as people are on manus and nauru they're sceptical and scared of going to a company like cambodia which has a bit human rights effort the australian government saying it is in discussions with several countries in the asia-pacific region about resettling refugees, what do you know about these discussions and who are these countries? >> the government can only send refugees to countries that have ratified the refugee convention, so that's a limited pool of countries when it comes to the asia-pacific region. there have been discussions with the philippines. they have not yet agreed. in past east timor has also been floated as an option. right now the only two countries that have aagreed beside cambodia and manus island and nauru what are the options for the people besides these offshore

detention centers? >> there are not a lot of options. it's either stay in indefinite detention or a prolonged of period of uncertainty on manus and nauru. they do have the choice to return home. unfortunately we have seen repeated situations where people from countries, even countries as bad as syria, have actually volunteered to return home rather than face indefinite period of detention on manus island thank you for speaking to us from sydney. south korea has announced sanctions against north korea over its recent nuclear test and rocket launch. they include putting into black lists for financial transactions. >> reporter: these unilateral sanctions are meant to heap further pressure on north korea coming on top of the wide ranging sanctions agreed by the

u.n. last week. they include verifying key individuals and organization $in north korea banning them from having financial dealings in south korea. there are also further restrictions on trade stopping vessels that have called in at a north korean port from visiting south korea for 180 days. also verifying and stopping the import of north korean exports through a third country. the restrictions go as far as encouraging south koreans when travelling abroad not to visit north korean restaurants which are seen as a source of much needed hard currency by north korea. all of these measures, according to south korea are meant to force north korea into taking another path away from the one that it has chosen so far. north korea, though, seems to show no signs of doing any such thing u.s. military commander say

a drone strike in somalia has killed more than 150 al-shabab fighters. al-shabab has confirmed the attack but saying the u.s. are exaggerating the number killed. al-shabab which has links to al-qaeda is fighting to overthrow the sew malian government. they're blafd for various attacks in including the nairobi attack which killed 67 civilians in kenya. the white house saying that strike was a presentative measure to prevent future attacks by al-shabab. >> reporter: the fighters who were scheduled to leave the camp pose a threat to forces in somalia. their removal, the removal of those terrorist fighters, degrades al-shabab's ability to meet their objectives, establishing bases, recruiting

members the government spokesman says they welcomed the drone attack on the al-shabab base in collaboration with the army. more weapons have been seized from a fishing vessel bound for somalia. australia is part of an international maritime force on patrol and it's not clear who was waiting for the weapons, but the shipment could violate a u.n. security council arms embargo. coming up, the search for answers to the biggest aviation middle of the of modern times two years after the disappears of mh370. mh370.

mystery and the disappearance of 239 passengers and crew. a vigil was held for the missing. many passengers were on board that flight. in beijing families of the missing demanded answers as they protested outside a butt history temple. last week debris found by the jet was found. the plane took off from malaysia bound for beijing in the early hours of march 8 2014. an hour later communications from the crew ceased and the aircraft disappeared from radar. it was tracked through military radar. transmissions indicate it then flew for hours towards the southern indian ocean following

this arch of western australian. before we talk about the search effort, an interim report has been published on tuesday. what's in it? >> reporter: that's right. this is the second interim report that has been published since the flight disappeared two years ago. the interim report is a report that has to be published on each anniversary of an aviation accident. this is in accordance with the resumes of the international civil aviation organization. it has to be issued on each anniversary until the final report is completed. unfortunately, there isn't much that is new in this report. it didn't contain information that isn't already in the public domain. so families, relatives of those on board who are hoping to get more answers about how the plan disappeared and why it disappeared will be disappointed.

however, there have been, as eyou mentioned earlier, two encouraging pieces of news that have emerged. two piece of possible plane debris was discovered and recovered, one from an imd and another in mozanbique. >> our teams are already on the island and we have to collect the debris and the debris is in our custody now. we will verify that the debris as soon as possible. we will work together with australia in verifying the debris. so we are waiting for the

officials to judges to make a decision two years on, do families of those missing still believe that they will get the answers they're looking for? >> reporter: they certainly hope they will get the answers they're looking for, but unfortunately not many are very optimistic. especially they point to the fact that little information has emerged. the only confirmed evidence that we have is a piece that was found on the imd last july 2015. that is confirmed as part of the wing. since then there hasn't been any other confirmed sightings of the

debris. it is being led by australian authorities. they plan to cover an area, huge area of 120,000 square kilometers. this is a difficult search. it is a place where the depths are immense, up to 6,000 metres or six kilometers. australian authorities have said that they are confident of being able to find the plane. the families are not so sure and they are extremely worried that when the search is expected, when the search comes to an end, which is expected some time this year, that authorities will deem that it is too expensive to continue the search. they've started a petition asking that the search be continued whether or not the plane is found once all 120,000 square kilometers have been searched thank you. lawsuits have been filed in the

u.s. where water leenched into the water supply of flint after the official $switched the water source to save money. >> reporter: these children have dangerously high levels of led in their young bodies. their family and six others have joined a class action lawsuit to hold local and state officials responsible >> what we're trying to do is to get action and get action quick for these families. the proper attention by the e.p.a., by the state regulatory agencies has not come >> reporter: the contamination began when state officials switched the source of the city's water in order to save money. the more corrosive water taken from a local river began dissolving led from old pipes. those led pipes are now being dug up. tens of thousands more will have to go says flint's mayor

>> this is a crisis and we can't wait and so the longer it takes us to do one line, the longer it takes for us to get to everybody else >> reporter: residents say ripping up the pipes won't uproot their fears >> it is scary because even though the pipes is there, we still have to worry about the water >> reporter: flint is sin onmaus with bad water but it isn't the only u.s. town with the led emergency. cities in mis, ohio others have found other levels of led in their water supplies. it is a powerful neuro toks in, particularly dangerous for the young who may suffer permanent loss of some mental abilities. some families in flint want someone to pay for putting their children at that kind of risk. rob reynolds women in mexico have come up with a novel way to deal with the capital's big harassment problem. more than half of the women in

mexican city reported being tormented in public, especially on public transport. >> reporter: it is often a fleeting encounter, but the anger and shame of sexual harassment on the streets can linger. these women are fighting back with a song and a confetti gunning. watch as they confront men who have made offensive comments or gestures at them. they're surprised, although all of them told us they were not embarrassed. they hid their faces or laughed nervously. >> translation: they're wasting our time. we don't feel ashamed because we didn't do anything. >> reporter: for the last three years these three women have been confronting sexual harassers through performance. they say they have endured on the streets of mexico city since they were children. it's time it ended.

>> translation: we live in a wrorld where everything revolve sz around men. we are not interested in educating men. what we want to do is to empower women. >> reporter: women's rye rights groups say educating men is key to changing attitudes. there is no law in mexico punishing street sexual harassment. even if there were, in a country where there is great distrust of the police may be difficult to getting women to report it. there are calls to an act of law. >> translation: any changes in the law is going to take time. so it's very important to take direct action to educate, to talk to other women. so they can identify the harassment and they can ask for help. >> reporter: only a handful of men have ever apologised. although they may not be seeing the results on the streets, the women say they're seeing results from within. >> translation: now i will more empowered and more confident about reacting and i stop being

afraid of working in the street. >> reporter: the women are spreading their message via social media and say they have received support from across latin america. they hope they spur a moment that is heard-- movement that is heard beyond the streets of mexico marie asharpova has failed a drug's test. she made a huge mistake at the australian open. she says she didn't realise a medicine she had been taking for 10 years had been recently added to the list of banned substances. the 28-year-old russian says she doesn't want to end her career this way and will face the consequences. >> i made a huge mistake and i let my fans down, the sport down, but i've been playing since the age of four that i love so deeply.

i now that with this i face consequences and i've - i don't want to end my career this way and i really hope that i will be given another chance to play this game a match like no other is about to get underway in south korea the world' best professional player of the chinese board game go will square off with an artificial intelligence system. there's plenty of money at stake, but the outcome could say a lot about the future of artificial intelligence. >> reporter: it was hardly l.a. calibre. he didn't sound too aggressive. if the style was low-key, the substance was a match for any big named boxer. >> translation: i won't let my guard down. given the time constraints i think i'm better. i don't think it will end up three two or anything. my prediction is either five nil

or four one. >> reporter: he is the dominant figure in the ancient chinese game of go. his opponent in the best of five tournament worth more than a million dollars is alphag developed by deep mind. he beat the champion last year. designers want to learn by playing the game's greatest. they want no arguments once they have beaten him >> we think this is going to be a very historic match so we wanted a legendry historic player, somebody who has been at the top of the game and acknowledged as the greatest player of the last decade >> reporter: it is simple. black versus white equal value pieces placed turn by turn. the complexity, especially for a computer lies in the sheer number of options open to each player and how to determine what makes a good move. to win a game you want to try

and control the maximum amount of territory that you can on the board. so you choose the intersection of the lines to play your pieces trying to avoid them being surrounded by your component because at that point they vanish. among these young children there's no doubt about the likely winner. >> translation: i think he knows more about technical moves. >> translation: i think he will win because when it comes to go humans are more intelligent than computers. >> reporter: deep minds designers are trying on way to combat human intuition rather than compute every possible outcome of every possible move. one to slim down the choices and evaluate against scenarios where one or other is moving at that moment. what if alpha go wins? >> if the machine can do that, that can be a kind of a different paradigm of

computation. so really human like. >> reporter: he says it will be a historic match. deep mind hope it will be the historic moment in the development of artificial intelligence much more news on our website aljazeera.com this is techknow. a show about innovations that can change lives. the science of fighting a wild-fire. we're going to explore the intersection of hardware and humanity and we're doing it in a unique way. this is a show about science, by scientists. tonight, techknow investigates the ivory trail they've tried to seize it, burn it, but nothing has stopped the terrible trade in illegal ivory.
