On his south american tour. Israel says two of its citizens are being held in the gaza strip at least one by hamas. One of the missing men disappeared last year. The details about him are only coming out now because an israeli judge has lifted a gag order. This is what we know. He is believed to have crossed the border fence into the gaza strip in september of last year. He is described as being of ethiopian dissent. This information is coming from the Israeli Ministry of defense. According to israeli sources, he is being held against his will be hamas. But hamas says it doesnt know anything about this. Israels Prime MinisterBenjamin Netenyahu says on twitter that his government is working to return him from gaza. His brother has called on the International Community to help find him. Translator my bother has been missing for the last ten months. It looks like he crossed the boarder into gaza and then disappeared. Were taushging about a humanitarian case because my brother is not well. On our familys behalf i ask the government of israel to do its utmost to bring my brother back safely. And i ask the International Community to intervene and put pressure to have my brother released. I also call on hamas to consider my brothers condition and release him immediately. What have you heard from his family . I understand they had a press conference earlier. Tell us more about that. Reporter yeah, that that snip that we just played was from a News Conference that took place just over my shoulder and the apartment block which the family home is in is just over the soldier. Were about five miles from the perimeter fence of gaza a stones throw, really and very easy for him to go and cross that barrier, and enter gaza. Exactly why he did it nobody quite knows, but the brother did give some telling details. He said his brother wasnt well. He said this is a humanitarian case. And speaking to people here, it would appear that he had a history of not being entirely mentally stable and also reports that he had been drinking on the day he vanished into gaza. In that said regardless of his motivation and state of mind israel is very concerned about his fate, and although it appears that he crossed the border voluntarily, whether he is still in a voluntary position to stay in gaza is entirely open to question. Israel says he is being held captive. Hamas denies that he is being held captive. So what else are we hearing from the israeli authorities, specifically why they think hamas has something do to with this . Reporter they say theres credible information to come out with that statement. They are not sharing that credible information with us. And as i said hamas is denying it is holding the man. Its a real difficult one, because for the past ten months the authorities have been advising the family not to go public with this. They advised them strongly that to go public might jeopardize the process of having him returned. And it might sour the ongoing efforts between israel and hamas through thirdparty intermediaries to agree to a longtime ceasefire for this region. A five, perhaps tenyear ceasefire agreement is underway. And if a hostage situation develops out of this situation at the moment then it would severely jeopardize those efforts. Paul thank you so much. Lets get the view now from gaza. Reporter a very curious situation here in gaza but one with very few answers. Al jazeera reached out to a senior hamas spokesman, and asked him whether hamas was holding either one or both of these israeli citizens. The answer to that was, and i quote, no comment. Still in the background of all of that of course is one year since israel began its 50day bombardment of the gaza strip. In that of course has been marked here in gaza by a ceremony including the unveiling of a monument in the center of gaza city. This monument is of a fairly large replica of a tank with a clenched fist rising out of it. In the hand of that fist are hanging three dog tags or military id tags. One of them bares the name of an israeli soldier believed to have been killed during that conflict, but whos remains are believed to be still here in gaza but the other two dog tags or military id tags bear only question marks, leading many to believe they represent the missing citizens. The number of Syrian Refugees has exceeded 4 million. 7. 5 million are displaced inside syria. Reporter 4 million and counting. Refugees in jordans camp didnt think the conflict in syria would last this long or force this many people out of their country. This is one of the camps oldest residents. He says two and a half years later, he has finally adjusted to life as a refugee, but had this reaction when we told him the number of refugees in the region had reached 4 million. Translator this is a disaster. It means the entire population will eventually be displaced. This makes me feel their conflict are will drag on for years and a return to syria soon is impossible. Reporter this man had lived in the camp before deciding to survive on his own in the jordanian border town but we returned two months ago. Translator i had to pay rent and it was so expensive. Refugees have to pay for a lot of services outside of the camp so i was forced to return. Reporter when asked what they want from the International Community, many refugees here say they want an end to the carnage in syria. The United Nations has called the crisis the worst humanitarian disaster in recent history, almost half of all of the people in syria have been displaced including 4 million who have been forced to leave for neighboring countries like jordan, and according to aid agencies there is no sign of when these refugees will be able to return home. The u. N. Says the International Community has been generous but the scale of the Syrian Crisis is so big that donors are thinking about how funding can be sustained as the conflict continues. Already this year people have less access to services. There are already agencies having to come back on assistance. Its pushing them back to the camps, which are funded entirely by the International Community or pushing them even to return to syria, and when you have families telling you im going back because i cant earn a living here and they would prefer to live in a war zone you know just how desperate they will. Reporter the u. N. Refugee agency says around 80 of the refugees are living below the poverty line. Another 70 are sending their children out to beg and are engaging in degrading or illegal work. Many say this is a sign of desperate people have become. Syrians neighbors who are takes in the bulk of refugees most of them are in turkey. Its home to 1. 8 million syrian ref fees. Tiny lebanon is hosting nearly 1. 2 million. Jordan has more than 600,000, many living below the poverty line. And only a quarter of a million are in iraq. More than 156,000 syrians have found refuge in north africa most of them in egypt. There are also 270,000 syrian Asylum Seekers in europe. The director of the middle east and North Africa Bureau for the unhcr says the number could be as high as 5 refugees those who did not avail themselves of registration there are another 270,000 syrian asylum seeshgs in europe several countries, and we have thousands of syrians attempting to cross the mediterranean, and some perished in that trip. This is the real crisis of our time. The Syrian People inside syria are suffering. About 7 to 8 million displaced, another 10 million impacted directly, and 4 million who are living in exile in the region are facing some of them utter poverty, problems with education, Health Income a lot of them depleted their savings, and also they are straining the communities, the bellies, and of the velages and towns where they live they are also facing difficulties because of the strainen energy, water, health education, and employment. The u. N. Says it holds south sudans president personally responsible for the self inflicted disaster facing their country. As you can see, the army is out in force to mark the fouryear anniversary of independence. For the people of south sudan, there is little to celebrate. The country has been engulfed in violence, tens of thousands killed, and more than 2 million displaced. Catherine soi spoke to some People Living under rebel control along the board we are ethiopia. Reporter this woman was fetching firewood northeast of here. She says she was ambushed by government soldiers. They allegedly stabbed and shot her multiple times before she was rescued and air lifted to this Red Cross Health center in the rebelheld area. Her brother said the security situation was not what he expected when he celebrated independence from sudan four years ago. Translator you get independence but you are still dying, you cant be happy. The conflict was not happening, i wouldnt be here. So how can i celebrate . Reporter at another Health Center not too far away this baby has her first medical checkup. She is days oil. Her mother say she just wants her child to grow up in peace. Translator i want the two sides to come together. Its only the leadership that can bring peace so that our children can have a good future. Reporter theres relative call income this part of the oilrich upper nile state, but many are poor and displaced. They receive humanitarian help but a few aid agencies often have trouble getting supplies from the capitol city juba. All of these people will go home with nothing. Some have walked for hours to get to this center. Most have been displaced from areas that far from here where fighting is still going on. Opposition leaders have been traveling across the continent in shadowed diplomacy, before talking begin. The rebel leader riek machar says he is still committed to the peace process. Im always hopeful that peace will come. Salva kiir if he resigns this is peace. You know normally if you look into history of wars the president that causes a war is never the person who brings about peace. Reporter as in governmentcontrolled areas, life is tough for everyone here. Food prices have more than doubled. Tough restrictions imposed by the Ethiopian Government at the Border Crossing has made it more difficult. Many are cautiously hoping that this time around the talks will bring them lasting peace. Lets bring in the spokesperson for south sudans president. He joins us live from juba. We very much appreciate your time. The opposition says that the president , salva kiirs constitutional mandate is done. What do you say to that . In actual fact when i hear this i thought it was a daydream; that the rebel leader tries to to think this was going to tend to be the truth, when in actual fact he doesnt have the capacity of speaking about the constitution, because he himself has rebelled against that constitution. And by talking about constitutions, he even surprises many simply because the man is a rebel, and we know the definition of rebel. If my english doesnt let me down, then a rebel is someone who has rebelled against the very constitution it is trying to upheld. So the president s tenure was extended by the people of south sudan, and the members of the parliament that they will lifted in 2010 election. The opportunity would have been availed for the people in april of this year but riek machar made the country to be in the war. He still now wants to be the president by all means, and all actually noticed this. So it is him who put the people of south sudan in a situation that they cannot go back to so what you are saying decide between salva kiir and those that want to contest him. Having said that what is your government willing to do to reach peace . There are millions of people that are terrified. 50,000 people have been killed. What is your government willing to do to reach peace . We recognize that this is a political war, and this one has been shown by this willingness to bring peace back has been shown by our president salva kiir. That is why he often travels, where everybody is being called with the opposition leader. There are no president s in the world that negotiate with rebel leaders, but the fact that he has been going out to to speak to riek machar even recently when the president of kenya called him, he flew to meet riek machar and as soon as riek machar sees the president he becomes more [ inaudible ]. He knows the people of south sudan are capable to decide who should be their leader. It is not something that you may enforce on them. Thank you very much. Nothing is for speaking on behalf of the president , we appreciate it. We appreciate you very much and your time. Thank you so much. Well be talking to the opposition ahead in our newscast. Thank you. Thank you. Plenty more coming up on the al jazeera news hour. Business grinds to a halt in greece.

Foreign ministers from western powers are locked in talks in the austria, trying to finalize a deal over Irans Nuclear program. They are trying to iron out remaining issues, and secure an agreement by friday so a document can be presented to the u. S. Congress. James bayes is live in vienna where the deadline seems to keep moving james. Tell us what are you hearing out of there . Is there optimism . Reporter well, richelle when i spoke to you a few hours ago in the blazing sunshine there was quite a degree of optimism the russians were saying they thought it was possible there could be a deal within hours. Well as you can see, the weather as turned and i think so has the at atmosphere of the talks. As you say the importance of this and it has become yet another deadline is the fact that in the congressional legislation about any deal, it says if you get the deal before the end of the 9th, thats today, then Congress Gets 30 days to look at it. If you go beyond the 9th and into the 10th then the Congress Gets 60 days, instead, two months, instead of one to look at the deal and thats something i dont think Anyone Around the table really wants. But they keep meeting, and they havent so foreman aged to do a deal. Interesting news coming in the last few minutes, were going to here from john kerry who is going to come out here to talk to reporters. My understanding is hes not going to make an important announcement. He is not going to tell us he has a deal he is going to we assume, say he still has problems, and thats not really what they wanted with that congressional deadline just hours away. All right. James bayes thank you so much. The taliban has denied reports that it has been in talks with the afghan government. A meeting in pakistan has been portrayed by local media as the First Official talks between the taliban and afghan officials. But the groups Political Office says those at the meeting were relatives of taliban members and were not actually representing the armed group. The u. N. Envoy for yemen says a ceasefire is expected to be announced in the next few days. He has held talks in sanaa. They are trying to end more than three months of fighting.

Thousands are gathered right there in santa cruz to see the pope. Lets bring in a journalist based in bolivia and joins us live from santa cruz. Tell us about the atmosphere the energy there that the pope brings with him when he delivers mass to crowds this large. Reporter it has been an amazing event. Thousands and millions of people 1. 2 to be exact are gathered here in the four corners, the most important here in santa cruz. People have slept the night with low temperatures to see the pope francis, and listen to his message, not only for latin america, but for all people in the region. What is the significance of the pope there are so many places he could have gone. What is he significance of his picking bolivia . Reporter well actually he is deciding to come to ecuador, bolivia, and paraguay because of the political issues that are happening in every single country. Here in bolivia, he has saided he wants a dialogue between chile and bolivia, and he pointed out that they need a way out to the pacific. It has been a very long day, and the people have been very emotional about this message. Because he put his criteria on point. The president has welcomed him to a country that has been invaded and purged out of its way out or exit to the pacific, so we believe his presence is not only about region and faith, but also about political points. The president and the pope have been meeting four times now, and he shared 35 minutes on palace in la paz. Leanna thank you so much. And if we can return to the live pictures that you were seeing, that is the pope as we said delivering mass to a crowd of hundreds of thousands, if not millions of people who have waited all day for this moment.
