Techknow report tonight. The battle over genetically modified cropped. And we begin with the iran nuclear talks. This vienna diplomats from six world powers including the United States are racing to try to wrap up an agreement. Officials say a few key issues still remain. The cur rointhd of negotiations has been extended three times since the original june 30th deadline. James bays is in vienna are more. Reporter with the key players, all seven Foreign Ministers involved in the talks, all in vienna there were hopes of an Historic Deal on monday. Translator we believe they cannot be and should not be further delays in the negotiations. Reporter but as the intense diplomacy continued, it was clear there were a few final Sticking Points still blocking a deal. Away from the cameras, u. S. Secretary of state john kerry and the e. U. Foreign fairs chief met with the Iranian Foreign minister. How did it go . I tried to find out. Is there a chance of a deal today representative . Are you making progress . Later dr. Zarif came out on his own balcony. Asked if there could be a deal by tuesday, he said possibly. One analyst told me everyone involved in the talks knows what is at stake if they dont manage to get a deal. If either party miscalculated and thinks the other side is in a position of weakness and more keen to get an agreement than than than it is im afraid this process can collapse, and if that gamble fails, basically, this opportunity is lost. I dont think it can be renewed a few months down the road because not only the parties will lose momentum but a tremendous amount of trust will be lost and thats the biggest asset in the negotiations. Reporter for the diplomats inside, and the journalists camping outside, these have become marathon negotiations. As the day once again turns into night, a deal still has not been done, and the round the clock diplomacy continues. Al jazeeras ali velshi has just returned from iron. Ali, what else do we know about the details that are being discussed tonight . We know they spent so much time on the major issues that they didnt think they would get through, that they gave short shift to the 2007 embargo on conventionary weaponry, the stuff of conventional war. I think everything thought we may not get to that and if we get past the nuclear stuff well get this done. And this has been a Sticking Point for the iranians. Youll remember before the revolution in 1979 iran was one of the biggest buyers of u. S. Weapons in the world, the shaw loved weaponry. It helped iran during the iran iraq war, but at this point, the western powers feel theres too much of this weaponry in the region. Iran is supportive of groups fighting in yemen, iraq syria, and lebanon. Russia has broken apart from the p5plus1 on this. They would be interested in selling iran weaponry and having a strong ali in the middle east. Right now their strong ali is the syrian government. So this is causing some them problems. There are also technical issues issues we have heard even about the wording of a u. N. Resolution. So it looks like they are getting to these final minutes. Our forces are telling us Different Things every half an hour. It looks like they might have a deal, they might not have a deal, so this is what the problem is. They are getting into these final moments and then they have to get their sign ups in the u. S. And iran from higher powers. How closely are the iranian people watching this . More closely than we are, i think. Their press scans a range of opinion from conservative to what they call reformists. This has been at the top of most newspapers every day with the exception of the most conservative newspapers. There was a move on friday to have people show up last friday of ramadan, this past friday normally a day of protest against israel hard liners asked people to come out and protest the u. S. And what they call the imperial powers of europe and this deal. Not as many showed up as they would have liked, which gives you scenes that hard liners are losing some ground in iran, and you dont know how many times in the last week and a half that i have seen reports that a deal is done inked, drafted, and ready for signatures. And its not true. So it does seem they are cheer leading this deal. All right. Ali thank you very much. You can watch ali velshi 10 30 eastern time, 7 30 pacific. Now to iraq and the battle for ramadi seized by isil this spring. Today Government Forces launched a major offensive to reclaim that city and all of anbar province. Its a Critical Mission and one that will test baghdads leadership and washingtons support for it. Jamie macintyre is in washington. Jamie . Reporter as you said both the pentagon and the Iraqi Government have a lot riding on this operation, which was largely planned by u. S. Advisors who were based at the air base. They came up with this twoprong plan to try to take back ramadi and orchestrate an assault on fallujah. They say the concept of operations behind this plan is to have the shia militias the Popular Mobilization forces engage isil forces in ramadi so that they cannot help the forces in fallujah so they cant help the forces in ramadi. And then the major assault is being conducted by Iraqi Security forces as they move against ramadi against the big road that goes right into the city. One of the things the u. S. Has done is advised them to encircle the city putting blocking forces to the south and west thats designed to present the isil forces from escaping to fight another day, something we have seen in the past. This was designed by u. S. Military advisors and they are hoping that its a much more deliberate and thoughtout plan that the one the iraqis were first going to pursue two months ago, when they were vowing to quickly retake ramadi. Thank you, jamie. Now to mike lyons, al jazeeras National Security contributor, he is in dallas tonight. This is the third offensive in anbar, what is the objective and can it work . Its classic divide and conquer. The intent is to separate the two isil forces there from reinforcing each other. But its definitely fraught with some risk that is the fact that there is still a disconnect with the arias sets that are trying to help this ground attack. There was an increase of those arias sets over the weekend. But they wont get that on demand type of support that they are going to need. The question is whether or not the shia militias will be able to infiltrate and put up a fight against isil against what is a very sunni area. Is this a positive strategic step . Im not sure that the sunni tribal fighters are engaged just yet. There has not been enough time since the pentagon announced the plan that they would be trained there. So that really hasnt happened. So they are going under the method of hope and once the fighting starts they are betting that some of those sunni tribesmen wont be agreeing with isil, and will turn and help the shia militias. Lets go bottom line here is this a plan that can work . You know, bottom line for it to work it has got to be a campaign that includes all of the military assets in really the air and on the ground and im not sure that they are that coordinated. And then you factor into this friction that exists between these two forces and also ga ga guerrilla fighting. You bring all of those together theres still a lot of risks, im sure the pentagon is going to say its going to a long time. We saw the rival of four f16 jets arrive. Are they going to factor into this . I dont think the four will have an impact right away. It will likely give the iraqi commanders some confidence that they are there. But they just havent trained as a combined arms team like we would in the United States in how we would fight this kind of war there. So you are going to see some not only civilian casualties but i wouldnt be surprised if you saw some frat are side because they just dont know how to operate that kind of power. How do you measure success . This i think you will measure success if they get back fallujah and then ramadi and then holding it. We havent destroyed the infrastructure, and then over the horizon shut off the supply routes in order to keep them held by the Iraqi Government. All right. Mike thanks very much. Now to greece after coming to the brink of economic collapse, greece made a deal with its european creditors, a 96 billion bailout. But it requires major concessions that includes raising taxes, cutting pensions and submitting to tough international oversight, plus if the Greek Parliament says no the deal is off. Jacky rowland has more from brussels. Reporter a deal at last. After talking that lasted all night, euro zone leaders emerged to announce that they had avoided the worst scenario. A greek exit from the euro. Today we had only one objective, to reach an agreement after 17 hours of negotiations we have finally reached it. Someone can say that we have anning agreekment. Reporter but its no laughing matter for the greeks. They need to adopt a large package of reforms in the next two days and agree to sell off 50 billion euros of state assets. A clearly exhausted Alexis Tsipras tried to put the best possible gloss on it. Translator the deal is difficult, but we have prevented the pursuit of transfer of financial property abroad. The plan was designed up to its last detail perfectly and recently had started to be implement. Finally we achieved the restructure of the debt and secured financing for the median term. Reporter Angela Merkel was categorical that none of the debt would be written off. Translator this success has come in spite of the fact that in the past few weeks and months the most important currency namely trust was lost between us, but paper is patience Going Forward what will be important will be what we agreed on during the night. Reporter these were growling talks for everyone. But the process is far from over. The idea is that half of the money raised for the privatization will be used to recapitalize the greek banks. A quarter will be used to pay off the debt. And the rest will be reinvested into greece. But talks on the bailout cannot even begin until the Greek Parliament passes the whole package of measures into law. So the european leaders drive away into the gray light of morning. Most of them can now catch some badly needed sleep, but not the greek prime minister. For sure the night was bruising for him. And he can only expect another brucing when he returns to face the parliament and people of greece. Jacky rowland, al jazeera, brussels. As we just heard the talks have ended in brussels but for families inside greece the crisis is far from over. Patricia sabga has more. Reporter this 73 year old and his wife lost their daughter to cancer seven years ago, and then they soninlaw two years after. They have been raising their rambunctious grand sons ever since. A tough job for any grand parent, but next to impossible on a pension and benefits that add upto only 824 month. Translator the money is not enough. If we didnt have support from neighbors and nonprofits, we would be finished. Reporter lacking the funds to cover even basic necessities, they havent paid their utility bills in six months a hand to mouth existence, and they are hardly alone. Translator they raised their childrens children and families are destroyed. People are completely destroyed here. And now in these last five months of negotiations its all over for us. The banks are now closed. Were in a catastrophe. Reporter the daytoday political jockeying of this crisis tends to command most of the headlines, but behind the figures and exchanges, another crisis is deepening, a silent crisis engulfing more and more greek families threatening to tear apart the very fabric of this society. This is the founder of smile of the child, a nonprofit that runs 14 care homes for 365 neglected and abused children in greece as well as centers offering food, medical services and counseling to families in need. Conceived by his son who designed this logo before succumbing to a brain tumor at the age of ten, smile of the child helped 82,000 children and families last year. The families right now are deteriorating, also theres a lot of lot of violence within the families a lot of domestic violence, also there are a lot of divorces so you see, there is a a domino situation. Reporter one thats now threatening this vital lifeline for greek familiar list. Smile of the child is funded by donations from greeks. Generosity thats become untenable in the wake of Bank Closures and cash rationing. They stopped to be able to support us so we have one week of financial survival. Reporter but he is prepared to do whatever it takes to keep this safety net intact. We will fight for the children, fight going away going to the states begging international, doing everything we can to show our cause, to show that there is a need to survive, please support us. Reporter an unwavering commitment to family excooed by these people. Translator as long as we are standing up even if we dont have anything to eat, we will go out and do whatever it takes to raise them no matter what happens. Reporter this does not bring any relief to these people. They are staring down the barrel of more pension cuts and austerity, and as for organizations like smile of the child, they are very concerned about whether the people who were giving them donations who havent been in the position to do so during Bank Closures theres no guarantee that they will be able to stump up more cash to help this charity. John. Patricia sabga reporting from athens. Theres much more on this news broadcast. Up next dozens of drug offenders pardoned by president obama. Well hear from one man.

The granted clemency to 22 drug offenders. Among those pardons with lavar wagh. Ashar qureshi talked to him today. Ashar . Reporter good evening, john. Last year the department of justice announced an initiative to prioritize clemency applications for nonviolent inmates. And lavar was one of those inmates. He earlier this year was granted clemency. Has about two weeks left on his penance and we sat down with him. This journey began when you were convicted of possession of 50 or more grams of crack cocaine. How long ago did that happen . And do you own up to what you did . Yes, i do. That was about 12 years, ago and i take full responsibility. And you were 25 years old. Yes. Looking at 20 years behind bars. Yes, i was. I had to sit down for a second to let it sink in. Like man, you are doing the wrong thing. You really need to get your life together. I just dont think i needed that much time. [ laughter ] but you think it helped . To an extent. How did you get to the point where you thought i want to seek a president ial pardon and why did you think you had a good chance at getting one . Well once i looked at the criteria, and i have a nice history a prison record of i went back to school. I got some college when i was in there, and i kept my nose clean. And i just figured why not. How did you find ut you were going to get the pardon . I got an email saying the president decided to change the sentence of 22 individuals today. So im going through the list. And lo and behold i run across my name. What do you think about the president s plan to grant clemency to nonviolent drug offenders . I think its a good thing because as far as crack cocaine issue, i believe that is that that hard stance on lets get tough on crime is not working, so i mean its for somebody to step up and actually take the initiative to do something about it is just paramount. Do you think these mandatory minimum sentences are too hersh . In what you have created is a one size fit all solution to a problem that i dont even think they really understand. I mean you cant just incars rate the problem away. You are officially set to be released at the end of this month. Theres a new life waiting for you. What do you intend to do . Right now im just trying to make sure i have the proper training to get out of here, get employed and be a productive member of society. And you think you can do that . Im ready. Currently under the doj guidelines some 75,000 inmates are eligible to apply for clemency, some 21,000 have done so. Some are scheduled for release on july 28th the others will be scheduled for release in november. John . Fascinating conversation asher, thanks very mump.
