It is 10 00 a. M. In greece less than a day before greeks begin casting their votes in a referendum that may determine the countrys future in europes single currency. Tens of thousands of greeks demonstrated in athens on friday. Here you say Prime MinisterAlexis Tsipras attending one of the rallies. He is encouraging people to vote no in the referendum which would essentially mean that greece does not accept the austeritydriven terms of a bailout plan offered by european lead leaders. Translator on sunday wed are all sending a message of democracy and dignity to europe and all of the world. We are resending a message of hope to the people because on sunday we do not simply decide to stay in europe we decide to live with dignity in europe. And a short walk away from that rally was this. A huge crowd of demonstrated to support a yes vote. A yes vote endorses the expired bailout terms. Mr. Tsipras came to offer promising to end harsh austerity measures. But many people say he has put greeces future in jeopardy. We will vote yes. We have seen what the government has done to us. In these five months they have taken us back ten years at least. One poll shows a razor thin margin between the yes camp at 44 and no at 43 . 12 are ollowing the Prime Ministers message which is by voting no greece strengthens its position for better bailout terms. But those in the yes camp say this is greeces only way to stay in the eurozone and europe as well. There is a lot of unclarity on the question which is base odden a proposal which is no longer on the table on a past proposal by the creditors to greece. So this all happens in a fairly confusing and polarized environment. We are looking at a referendum that could determine greeces future in europe and at a time where the banks have remained shut for a week and at a time where we know there is only sufficient money to go around until monday. We had that confirmed by the banking association. So greeks go to the polls with a hell of a lot at stake if you want to put it that way. What if greeks say yes . Who takes over the country . Reporter depending on what happens at the referendum on sunday the financial minister said he would not be prepared to sign a deal with the creditors unless the issue of debt relief has been addressed. This has been a key issue all along in these negotiations. Greece has asked for debt sustainability and relief has been to agreed to before a new deal is signed. And an imf report suggests this is the kay. But europe is saying they want to see reforms first and then discuss the issue of debt sustainability. We could be looking at a lot of political changes, a lot of Political Developments ahead on who heads these negotiations and under what terms. But what is certain is that a solution is needed soon. Without a Banking System the economy is frozen. Most transactions are frozen. We are hearing about problems in supplies. We know that people are having trouble getting the daily allowance out of atms. So whatever happens on sunday some solution really needs to be found very fast or we aring look at a dire dire economic situation. We hope it doesnt come to that Elinda Labropoulou thank you for that. While greek officials argue its the regular citizens who are paying the highest price. Supermarkets say that supplies could soon begin to run short and greek banks remain shuttered for almost and entire week leaving people in retirement with little access to their money. Translator they dont give money to us. They gave me 120 euros is day before yesterday and i went and bought my medicine and i had to pay 33 year owes. Now they tell me to come back in a week. How will i live in this week . Very sad. The crisis has ramifications all over the world. It impacts your money. Our reporters explain how and why. Greek banks are closed for one simple reason. There are too many depositors too many people trying to take out too much money. Before long they are going to completely run out. For the last few weeks, the European Central bank has been funneling money out the backdoor and it is going straight out the front. And now there is no more money coming in they had to stop it going out. If this is happening in greece why are world marks in turmoil . It depends how much exposure there is to greece. In the u. S. There is little direct exposure but its the uncertainty. And the safety net of the ecb is no longer available to give emergency money to degrees, thats keeping investors on edge. Greece continued to continue that queue. That queue going down. Many people sheltering from the rain. The majority of people have been able to take out the limit of 60 euros. But several pensioners have not been able to eke out a single euro. The reality of the crisis may set in in a couple of days. A run on a bank in a modern economy is bad for everyone. If you are a traveller, bring a lot of cash to greece. You cannot rely on the Banking System. That could hurt tourism for greece. For everyone else it marries to your money and your 401 k . If europe becomes destabilized because of what is happening with greece that affects anybody who makes or sells a product in the United States to europe. The eurozone is americas largest trading partner. The greek banks need to know that there is more money coming towards them. Depositors need to know their money is safe. Once people know there isnt a banking crisis and the money is safe they stop demanding it. Its a difficult problem trying to stop a bank run but thats what they have to do. When the greek people make their choice on sunday cnn will be in athens. The polls open at 7 00 a. M. Local time across the country. Our day of live polls will have more. We turn to the philippines.

Greeks go to the polls on sunday for what is a polarizing referendum on how to handle the debt. Thousands rallied ahead of the vote. A yes vote supports the debt relief. And a no rejects it. Heres the question that will be on the ballot papers. It is not schismimple. Should the Draft Agreement submitted by the ecb, imf at the euro group on june 25th which consists of two parts that make up their full proposal be accepted . And thats the question. And the first document is reforms for the completion of the Current Program and beyond and the second is preliminary debt sustainability analysis. Yeah. Nina dos santos takes a look at what happens no matter what the greeks answer. Reporter yes or no one of these two words will decide greeces destiny and with it the future of the single currency itself. Unable to find Common Ground with creditors, athens asked its people whether they accept or reject reforms set out as part of the countrys second now expired bailout. The eurozone and imf want a yes. Greeces government lobbied for a no. Either way the stakes couldnt be higher. Translator even in the case of a yes vote we have to face difficult negotiations. In a no vote the greek position is dramatically weak. The Prime Minister and finance minister could give way to a new government which would enter fresh talks with the creditors. Greece may eventually get the money it needs to open up its banks and pay back its debts and think about a fresh package in aid from here. It makes an exit less likely but expect swift austerity as part of the conditions. We have seen a small element of what can happen of not being able to get money out of banks in small amounts. And nobody can really say how it would work out under that scenario. If greece votes no all bets are off. They would push for renewed negotiations and concessions on debt relief. The banks would remain shut and greek greece could be kicked out of the euro. The people would be poorer and the markets pray to uncertainty. A no vote is associated to a painful situation. The situation is already painful in greece at the moment. I believe the bank will remain shut for a longer time. It will trigger the support of the ecb to the greek financial sector. You might expect a collapse of the economy. I do not think that the euro group and they have made it clear that a no will hurt negotiation. Greeces leaders have pitched this as a referendum on austerity. But europe sees it as vote on the membership of the euro. Whatever it means to each side athens could be words away from a dramatic rescue or financial disaster. We want to show you what the greek people are dealing with the raw emotion of one greek citizen directly affected by this crisis. These images of a desperate elderly greek man struck a chord with our team here. Some banks are Opening Doors to people without a bank card. You see him sitting defeated on the ground. He is being assisted by a Police Officer and staff member of the bank. You can certainly see the distress on his face. He could withdraw at most 120 euros from this bank. His future like so many others seems uncertain. That is heartwrenching. To syria now. An explosion at a mosque killed 25 al qaeda members. The dead were part of an al qaeda front. They were gathered at a meal where muslims break their fast in the holy month of ramadan. Some are blaming isis militants. So much news out of syria is all about war, death and destruction. But our next story shows how something extraordinary can always rise up from terrible loss. A syrian teenager whose family escaped to jordan spends her time making sure other refugee girls stay in school. She has earned the nickname, the syrian malala. Translator i left syria two and a half years ago for various reasons and problems in all of lifes aspects in education, making a living and freedom of movement as well as other related difficulties which led to being unable to stay in our own time or move to another place in syria. Therefore we decided to leave and move to jordan. Being a refugee does not mean an end to a life. On the contrary you have to be stronger to be able to help your country and the people you love. Even if you are a refugee you is to be strong to face these problems. I notice that a lot of people dont like education and because i really like education i decided i should start to advise people even if they dont take my
