went wrong 10:30 eastern 7:30 pacific. i'm david schuster in for l ali velshi. on behalf of all of us at "real money" thanks for watching. watching. it's now up to the jury. after weeks of emotional testimony deliberations start tomorrow at the boston bombing trial desperate pleas for help in syria. >> we are not on anyone's side thousands struggle to escape the yarmouk camp overcome by i.s.i.s. the debate over the iran

nuclear deal. president obama called it our best bet yet chicago voters are ready to choose the next mayor. >> chicago is one of the most violent cities in the country. why? broken promises. how the issue of gun violence my be critical to the race. >> good evening, i'm antonio mora this is al jazeera america. tonight, the fate of the accused boston marathon bomber is in the hands of the jury attorneys on both sides delivered their closing arts in front of a courtroom full of victims and the media. erica pitzi has more on the statements from the prosecution and defense. >> experts say a guilty verdict is pretty much a foregone conclusion. both sides used their closing arguments to paint their own pictures of what happened. after the guilt phase comes the penalty phase and jurors will died whether this 2 #-year-old lives or dies.

>> he wanted to terrorize the country, punish america for what it was doing to his people. those are the words of the federal prosecutor as he delivered his closing argument to the jury. several survivors of the attack were in the courtroom along with family members of the victim like the father of 8-year-old martin richard, the youngest victim dying at the blast not far from the finish line. people from the courtroom wiped tears from their faces. thousands of spectators were gathered at the finish line when two bombs exploded. three died. 260 others were injured. over the next four days the city came to a halt as investigators searched for the prime detectives - tamer line and

dzhokhar tsarnaev. the two brothers wreaked havoc. they shot and killed a police officer, shaun collier, and hijacked an s.u.v. and held the opener at gun point. tamer line died after a shoot-out with police and dzhokhar tsarnaev escaped. he was captured in a boat. his lawyers acknowledge that dzhokhar tsarnaev carried out the attacks, but that tamer line was the real mastermind. the defense attorney told et jury: person the defenseman says the only pictures from tama line and painted a picture of dzhokhar tsarnaev as succumbing to his older brother's radical relief. the prosecution pushed back saying they did this together.

both planting a bomb. the prosecution had the burden of proof, it had the last word delivering the core of their case saying that dzhokhar tsarnaev chose a day when the eye of the world would be on boston there would be civilians on the sidewalks, and he targeted them - men, women and children. dzhokhar tsarnaev is charged with 30 counts including murder, and for that jurors have to decide unanimously to convict him. we could hear a verdict as soon as tomorrow. a north carolina judge ruled the prosecutors can seek the death penalty in the murder case of three muslim students. their accused killer steve hicks appeared in court in durham. prosecutors say he shot three of his neighbours in the head and it may have been sparked in a dispute over parking cases where hicks and the three lived. investigators are investigating whether it's a hate crime. >> the kenyan military launched

strikes on al-shabab in somalia. two bases in the ghetto region were attacked. it borders gennia. -- kenya. it is days after the deadly siege in garissa university. al-shabab says it was a mission the united nations says the war in yemen is pushing it towards a disaster. as the red cross is trying to deliver medical supplies to aden. we obtained this video of a battle between shia rebels and forces loyal to abd-rabbu mansour hadi. some areas of the city had no electricity or water for days. you can find more on the situation in yemen on a special section on the website the palestine liberation

organization is telling al jazeera a rescue nation is under way in syria's capital. the u.n. described the situation as beyond inhumane. i.s.i.l. fighters stormed the camp. it's a few miles from damascus. they were in almost dealt control of the camp. thousands remain trapped. a few hundred escaped. stefanie dekker has more. >> reporter: the palestinian army showed these pictures. >> in 30 minutes they could have executed all in the school. i.s.i.l. called from the mosques, if we catch one of you the palestinian group fighting or with the government they'll cut our heads off: this camp has

been besieged by more than two years because rebel groups are based here. now i.s.i.l.'s experience and the regime in a densely populator camp is making the situation worse. some made is out. most of the 18,000 that tried to survive are trapped. >> we cannot pay for anything we are not on anyone's side. we want the camp to be safe. >> reporter: the palestine liberation organization is sending a delegation to syria. noate is making it into the -- no aid is making it to the camp. we are told that the lack of supplies is making it impossible to treat the wounded.

i.s.i.l. storming the camp came as a shock iraqi teams began to excavate 12 mass sites at a military base. the camps may hold the corpses of as many as 1700 toldiers. the recruits from massacred by i.s.i.l. a video of them being machine-gunned to death was posted online and became a symbol of brutality former contractor edward snowden was grilled by an unlikely interviewer. how many of the documents have you read? >> i have evaluated all the documents in the archive. >> you've read every one. >> well i do understand what i turned over. >> there's a difference between understanding what is in the

document and reading what is in the documents. >> i recognise the concern. >> because when you land over thousands of n.s.a. documents, the last thing you want to do is read them. >> i think it's fair to be concerned about did this person do enough were they careful enough. >> especially when you are handling material like we know you are handling the interview took place in moscow where edward snowden was living. edward snowden said americans should not have to change behaviour because a government agency is doing the wrong thing. >> a fraternity accused in a "rolling stones" article about campus rape is fighting back. it says it will sue the magazine. "rolling stones" retracted the story after an independent review that found the reporting behind the article was flawed as soon as negotiators announced an agreement on the iran programme critics say it

wasn't good enough. coming up, their argument and why a better deal may be realistic. and why some of the force gun fire in the country may be realistic.

and hoping to silence his critics critics president obama is out defending the name work agreement reached last week with iran over its nuclear programme. many obstacles remain in the u.s. and abroad before a deal can be struck in june this is the best bed by far. >> reporter: selling, that's president obama's mission this week as he looks for support for the framework agreement. to scale back the nuclear programme. in an interview with the "new york times", the president said it repeated a once in a life-time opportunity, and wants to work with sceptics in washington. >> my hope is to find something

allowing congress to express itself but does not encroach on traditional presidential prerogatives and ensures that if in fact we get a good deal we can implement it. >> reporter: the president says it would enforce compliance and snap back sanctions if tehran violates the agreement. and warns of consequences if the agreement is torn apart. >> translation: if iran violates the agreement, we can return to the counteractivities. >> reporter: president obama has detractors abroad namely in israel. >> endangers the region, the world and anyone listening to me now. >> reporter: in any nuclear deal binyamin netanyahu said iran must recognise the state of israel president obama told n p.r. that is highly unlikely.

>> the notion that we would condition iran not getting nuclear weapons and a verifiable deal on iran recognising israel is akin to saying that we won't sign a deal unless the nature completely strans forms. that is i think, a fundamental misjudgment. >> reporter: meanwhile the issue of sanctions divides washington. the white house says any sanction relief if a deal is made. will be phased out over time. >> it's the strong view of the administration that it would not be wise or in the interests of the international community to take away sanctions, all the actions on day one. >> reporter: next week the senate foreign relations committee plans to vote on legislation helping with the final agreement. >> some lawmakers can't the

power to lift sanctions while congress debates the deal. >> paul carol is the programme director and former u.s. department of energy official and joins us from san francisco. good to have you back. what are the state administrations of your organise aches, one is to prevent new -- organization one is to prevent new nuclear states. do you thigs it is a positive step to preventing iran becoming a nuclear power? >> thank you for having me. i think the deal is more than anyone hopes. skeptics, and supporters alike. the level of detail in the joint statements the fact that all of the paths to the bomb that iran could have pursued from uranium to plutonium have been processen and rolled back. it's what the international community was after. this prevents their path to a

bomb. >> you probably herd lindsay grahamle sarcastically saying this is the best deal president obama could have gotten echoing critics saying a tougher stance would have gotten a better deal than we have so far. do you think that's the case? >> i don't think that's the case. you have keptics and opponents, what is remarkable is in the past day or two since the deal was announced and the details revealed skeptics - these are sent rift elites and experts. people that are sceptic came out on the deal supporting the deal. they are former republican officials, heads of our own c.i.a. and national security. >> some democrats opposed the deal, and one who does not is former clinton survivor sandy burger who wrote a piece saying

the u.s. couldn't go so far because the international community may not go along. do you expect the senators in the house to come up with a veto-proof majority with tougher sanctions that could scuttle a deal. >> i think they could come up with a veto-proof majority and that is what we are pointing out. the sceptics have come around many are democrats, and some republicans. the republicans don't want a deal and hold outs a mith that there's a better deal to be had. these are folks that want to see iran permanently weakened or diminished or hold out for a military option which is no option at all. >> if there isn't a better deal. an argument is while the iranians may not get a bomb now, the 10 year framework allows them to get one in the future. mitch mcconnell, the senate

majority leader says it sanctions an internationally sanctioned 10 year nuclear development programme for the iranians. what do you say to that? >> that's comply obfuscation. it is not something that allows them to have the breakoutline capacity the next day when the 10, 15, 25 year timeframes ended. the point of the deal is to extend the amount of time the international community and those on the ground can detect or give warning. it's a misconstruing of the facts and deal to say if goes to 10 years, and on monday when it end, the iranians can get a bomb. it's not true. >> good to have you with us thank you senator rand paul is widely expected to announce his campaign for president tomorrow. the republican kentucky law-maker released a tees are of a campaign video today.

compared to the same period last year. >> crime and violence is an issue in chicago, especially through political season. >> mick said it's an issue that is politicized. >> it's difficult for an office holder in a place like chicago, which has complicated crime problems. it's difficult for them to use it as an issue. they are on the defensive. >> it's been a tough issue for the mayor, touting games and crime fighting and being sensitive to residents touched by violence. >> we will not rest we cannot rest until every parent in every part of the city enjoys the same sense of security that others experience and come to expect. >> the mayor and superintendent say the steady flow of guns is at the heart of the problem. chicago police found 7,000 guns. a poll suggests the mayor is

leading garcia 58-30% a margin increasing closing in on election day. >> whichever candidate gets the chance the real question is if he can stem the violence before mums have to bury more of their children. >> the garcia campaign is confident. both sides will need a sizeable voter turn out, which may be a challenge given pass over and eastern holidays and the fact that the schools are on spring break. thank you. still ahead on al jazeera america. people have been debating the meaning and lyrics to "american pie" for four decades. an auction is giving us a look at the song and what it's about. also a little invention that could revolutionize everything from the smartphone to the electric grid.
