first underground farm. ♪ ♪ let's begin with greece where uncertainty looms over the future of its roll in the euro zone. 1.6 billion euro payment that it owes the i.m.f. is due today. but the government looks set to default. thousands of pro-government supporters have rallied in athens to back the government's rejection of a tough bailout. and sunday people will vote on whether to accept or reject a deal. meanwhile, the greek economy is slowly grinds to go a halt. banks are closed and people have been lining up outside cash machines for daily withdraws that have been capped at 60 euros. barnaby phillips is live for news athens. barnaby, it's a really historic moment almost unprecedent i had think for an advanced economy to

default. what happens after midnight is the big question? >> reporter: in practical terms you won't see a change on the greek streets. the atmosphere has been electric in athens for several days, but that failure to pay the i.m.f. and greek government sores are saying they won't payback the i.m.f. you are right it puts greece in some soup justice economic company. zimbabwe somalia very different to a euro zone economy with all of its supposed strengths. but it doesn't make an enormous change, it means it's in arrears to the i.m.f. signals a disastrous relationship with the i.m.f. much concern within that organization that so much money was lent to greece, a real headache for christine leguard. a technical default will be when

greece fails to payback money to the european institutions, the european institutions which have leapt it mon, that will happen later in july. it's another step towards greece sliding out of the euro zone. but it isn't in it's itself the decisive moment. >> all right, we have a big question,, greeks have to answer a big question on sunday. what pay is public sentiment lean on this referendum? >> reporter: it's really difficult to say. sami. there have been opinion polls and, they are contradictory. some show a no vote. that is lining up behind alexis tsipras, a vote of defiance if you like, and some greeks certainly believe is his message that if the greeks reject proposals that were on the table from last week, he can still negotiate from a stronger position with a democratic mandate. we saw a big crowd on the streets of central athens last

night supporting the prime minister. i thought personally there were more people there than i had suspected would turn out. but on the other side, perhaps there are people who are having cold feet at this statement, i don't think mr. tsipras would have wanted to have gone in this recommend run dumb on the back of banks having been close today an entire week. those are the circumstances in which he's had gone to fight. and his opponents are hammering home the message that sunday's vote will be a vote between the euro or the drachma. and interestingly europe's leaders are not staying out of the fray. they are weighing in and trying to influence the vote. we saw jean-claude say it yesterday, and the italian prime minister theoretically somebody who ought to be sympathetic to mr. tsipras talking along the same lines it is a our ore or drachma vote. how do the foreign interventions play on the greek psyche, they

will frighten some people. they'll make other greeks everybody more determined. they will say look, we have put up with austerity for five long years, it hasn't done us much good. we see no economic recovery in sight and so we will defy you. very interesting to see how it plays out on sunday. >> indeed. thanks so much, barnaby for now. let's continues this discussion with dominic kane he's in frankfurt where the european central bank has its head quarters. the big question there will the european central bank continue its emergency funding for greek banks as we continue in to uncertainty? >> reporter: no sign of that sami. you'll recall in fact they said on monday that they were capping the e.l.a. the emergency liquidity assistance that's been effectively a life line for the greek economy for a considerable amount of time. they were cam it at the friday level. around about 90 billion euros

cumulative overtime. we were speculating on sunday and monday about whether the greek economy had drown down all the money from the existing e.l.a.s the fact that such draconian measures are in place banks being closed, small amounts being limited being able to be taken out of cashing machines would suggest that all that money has been drawn down. the newspapers in germany are saying, it talks about greece being the land without banks. saying that the future is being a bit do the approximated the e.u. is being decided there. europe is holding the door open for greece, which goes against the suggestion that the euro zone leaders are saying it's the euro or the drachma that people are voting on on the week end the. the financial times saying greek voters warn bailout rejection

spells no to europe. you have there a sense in the media around our that up this bank being held this weekend is going to be decisive in one way shape or another. the greeks are having to decide whether they want to be full members, let's remember that e.u. treaties commit countries to ever closer union and that the euro, the single currency is seen as being an expression of that desire to be part of this ever closer union. the question will be if they default out of the euro, the euro zone is that ever closer union finished? that's the question perhaps to be decided on the weekend. >> all right thanks so much dominic kane there. now we have an update for you on the crash of an indonesian an military plane in sue mott rah with the number of dead now at least 20. the plane came down on houses in a city and exploded in flames. the army says 12 crew were on board. there is also a financial crisis in puerto rico the

government there says it won't be able to repay a debt of $72 billion. the governor of the u.s. territory wants to defer the payments so he can renegotiate with creditors. andy gallagher has the latest from the capital san juan. >> reporter: puerto rico has been in recession for close to a decade but the island's stagnating economy now pales to its inability to pay more than $70 billion of debt. the publically-run power company alone owes $9 billion, the governor's admission that puerto rico now stands on the edge of an economic death spiral has brought things to a potentially catastrophic head. in a televised address the governor garcia padilla told the nation hard decisions will need to be made. >> translator: the only way we'll get out of this hole is if we join together as a country and are all willing including bond holders to assume some of the shared sacrifices today so that tomorrow we can also share the benefit of a growing economy

economy. >> reporter: at the campus of the university of puerto rico students reacted angry to the speech. many here feel budget cuts will unfairly target them for years to come. >> the people who suffer is us, the students, the students that will follow news in the next couple of years, that is the generation that has to pay for the past consequences. >> reporter: but attempts to cut spending and restructure debts have so far failed. and now few options remain. the sign here behind me reads people before the debt. but for puerto rico there is now no golden ticket. whatever happens in negotiations, in the next few hours, days or even months, this island faces years of hard times. puerto rico is a territory of the united states and much of the debt is held by u.s. investors. it doesn't have the same status as other states it's been made clear it won't get any financial help from the mainland. >> there is no one in the administration or in d.c. that's contemplating a federal bailout

of port ridiculous only but we do remain committed to working with puerto rico and their leaders. as they address the serious challenges, serious financial challenges that are currently playingflailingflailing playing the common welting the poured rico. >> reporter: nine deadlines are coming and time is run out. in a ran's foreign minister is back to discussion after he had been back in eye tanaka ran briefing. negotiateses in vienna now seem likely to continue until later this week. kelsey davenport joined us from vienna the director of nonprolific raise at the arms control association. good to have you with us, first of all, do you see the return of iran's foreign minister with these top officials as a sign that talks are making progress, they are getting to a critical

stage in. >> well, the political will is clearly evident on both sides to reach a comprehensive nuclear deal within the next few days. i think foreign ministers minister's return is crucial. it's important that he's bringing back with him the head of the on top i can energy organization. he has important technical experience and will be crucial to filling these remaining gaps. >> do you think differences can be made up? >> absolutely. when you look at what they have already accomplished in terms of reaching an agreement on sensitive areas these remaining differences are small and very resolvable. we are already hearing that there is progress on resolving these concerns and comprises are certainly evidence that will meet both of the concerns of the international community and

iran. >> to what extent will any agreement get in to what happens to iran's nuclear production capabilities after a decade? >> well, some of the restrictions on iran's nuclear program will last beyond 10 years. including access to sensitive sites, and increased monitoring and verification on iran's nuclear fuel cycle. this will help insure that iran cannot move towards nuclear weapons quickly and cannot develop a covert nuclear weapons program. so simply, the deal won't end after a decade. many of these restrictions will continue some for 20 years some indefinitely. >> ultimately, i mean, your organization has a very clear goal, if you want to create a middle others that is free of these sorts of weapons, you know, doesn't there need to be one rule for everyone in the neighborhood? israel is widely believed to have a nuclear arms program. other countries are feared to

develop one if they feel threatened by other states. >> well, i think that a nuclear deal with iran will help lay the groundwork for standards in the middle east that will hopefully discourage countries from pursuing nuclear weapons programs. a nuclear deal with iran would be a net plus for nonproliferation it would limit iran to a civilian nuclear program and put in place more intrusive monitoring and verifications. this is a standard that could be applied to the entire region. >> let's hope it will be, thanks so much for your thoughts. still to come on the show, south africa is closing a camp sheltering victims of seen phobic violence. what next for the refugees? we'll be there live. and a tense election in burundi. the opposition boycotted and african union observers stayed away.

welcome back. let's recap the headlines here on al jazerra now. a 1.6 billion euro payment which greece owes the i.m.f. is due today but the government looks set to default. thousands have rallied in agent ends to back the government's rejection of a tough bailout. the military cargo plane has crashed in the indonesian city killing at least 15 people. the jet exploded shortly after take off. puerto rico says it can't repay a debt of $72 billion. the governor says he wants to renegotiate with creditors. in south africa, the only remaining kamphausing people who

fled april's seen xenophobic violence is set to close. most people at the chatsworth interim sell ter do not have u.n. refugees status, joining us live from the camp, so where will people go? >> reporter: sami, the people here are concerned about returning to communities they fled up to three months ago when xenophobic violence took place they came to the shelter seeking refer huge and safety and they say it's still not safe to return to those communities and many of the refugees here are eighth freer burundi or the democratic republic of congo and the people here are sort of left in a position where they are stuck between a rock and a hard place saying they can't return to their countries of origin either. and also very importantly is there are concerned about refugees status, many of the people here are having difficulty in renewing their status at the respective offices here. and because of that, they worry

fa if they go back to their communities they will be arrested by the police for being in the country illegally. one of the people concerned about returning to the community is daniel, he is from the democratic republic of congo. when you leave here today daniel, as the camp is -- the shelter is set to close where will you go? >> honestly speaking i don't have any options. >> i don't know where i am going. i can't fight with the government. as they are closing the shelter and it's not like we have been integrated popperly we are being forced to leave the shelter, we don't have power to fight the government so we are going to see where we can go. >> reporter: are you concerned about safety in the communities that you lived in before? >> he request. certainly that's a colonel. some people beat us. they are still in the community and nothing has been done to address the issue you of xenophobia, we are going back to the same issues which we ran away from. we really are having a fear to go back to the community but we are forced. we can't go back on our country of origins, there is a war and

we are forced to remain in south africa. which we didn't like to remain in south africa because the issue you of xenophobia is not addressed probably as needed. >> reporter: -- properly as needed. >> reporter: do you think there has been enough to address your status? there this is there no helpful people have orders to leave the country and they have been given the orders to leave the country while we are in the sell ter under xenophobia attacks and we don't know where to go. they don't know where to go because burundi is under war here they don't have documents when we leave the camp outside the police will arrest them and put them to jail. also the element to makes people fear going back to the community. >> reporter: daniel thanks have. i was speaking to daniel a refugees here at this shelter in chatsworth. now there are about close to 200 people who remain here. they say they would rather sleep on the streets in this area rather than return to communities where xenophobic violence took place up to three months ago sami. >> thanks so much. turkey's national security

believed to be the kurds next target, it is the last isil controlled crossing on syria's border with turkey. and its fighters are seen in the distance planting explosives. the coalition is likely to provide air cover in a battle that would weaken isil think but syrian activists are questioning the motives of the u.s. and the kurds. >> translator: the y.p.g. is now at the doorsteps if they capture that crossing, they will then push south to the kurdish areas linking them. >> reporter: the turkish government wants some sort of military intervention to stop the kurds' expansion but the military is believed to be reluctant to make such a controversial move. already the p.k.k. which has been involved in an armed conflict with turk foy decades said any intervention would mean war. zeina khodr, al jazerra, on the syrian-turkey border. amnesty international is accusing egypt of crushing an entire generation's hope for a
