>> well allow me to take you in the direction of our website. aljazeera.com. you can see the main story there about iran's nuclear deal but all the top global stories are there. aljazeera.com. . >> we don't trust iran, and we shouldn't. >> white house press secretary josh earnest tells al jazeera america the administration is staying wary a day after making a deal with tehran's nuclear program. a day of mourning and calls for swift justice after al-shabab storms an university in kenya killing nearly 150 people. and disappointing news on the economy. far fewer jobs created last

month than expected. why cheaper oil is in part to blame. >> this is al jazeera america. i'm libby casey. praise stretched from washington to tehran today. iran's president has promised that his government will honor the deal but only if world powers will hold up their end of the bargain, too. >> i would like to make cheer that the enrichment program will be be for energy. >> it is warned that they will still be able to build a nuclear

balm. >> prime minister netanyahu spoke to a joint session of the u.s. congress just last month warning of a deal with iran. he'll no doubt try to use his leverage whatever leverage he has with u.s. lawmakers to try to scuttle any chance of this passing through congress. but it's very unlikely that he will be able to derail this bill. this is in agreement reached not only with the u.s. but also with other world powers as well. mr. netanyahu, who will no doubt continue his criticism of this agreement will struggle very much to prevent any kind of final deal being reached. >> here in the u.s. the obama administration has to convince some skeptics in congress not to take action until the deal is done. white house press secretary josh earnest spoke with stephanie sy

about the challenges that the administration faces from capitol hill. >> let's start with what congress should have with any final deal with iran. should they have a right to accept or reject a deal of this magnitude? >> what we've said about congress is that they've played a critical role from the beginning. what we've said throughout this process is we've kept congress in the loop, and at some point it will be the responsibility of congress after iran has demonstrated over the long term a willingness to comply with the terms of the agreement it will be the responsibility of cross to ultimately decide whether or not those sanctions should be removed. we do not believe that congress should remove those sanctions any time in the near future. and that frankly is because we want to see iran demonstrate some sustained commitment to living up to the terms of the agreement before we dismantle the architecture of the sanctions that forced iran's negotiating table in the first place. >> should congress, at least have the opportunity to review the final deal and sign off on

it? >> well, for decades longer than that, for generations the united states president falls into the line of previous president's foreign policy. >> why should the u.s. trust iran now if as the iaea, the nuclear watchdog agency has said they have been caught building nuclear facilities in the past. >> i'll be blunt with you. we don't trust iran and we shouldn't. they've tried to undermine or evade the work of international inspectors. that's why our approach has been to december trust and verify. that's why in the context of this agreement we see the most intrusive stringent sanctions that have ever been put in place

against a country's nuclear program. and these are sanctions that don't just apply to iran's nuclear facilities. these apply to the you uranium mines inside iran. this would apply to manufacturing facilities that supply centerfuges, to make sure that they're not building a covert program. it boo include regular access to the universal facilities that iran already has. this is why we can be sure that from beginning to end we can have a very detailed understanding of exactly what iran's nuclear program looks like and ensure that it is not being used to build a nuclear weapon and only used in peaceful purposes. >> when it comes to sanctions would you clarify how the lifting of sanctions has worked? how has that been worked out. will the u.s. sanction simply sees? >> the president was very clear.

the president was clear what we envision is a phased relaxing of sanctions. we need to see iran in a sustained commitment to living up to the terms of this agreement before we take away the sanctions. >> israeli prime minister netanyahu said that this deal would pose a grave danger to the region and the world. critics say this will only empower iran, besides threats to israel is backing houthis in yemen and bashar al-assad. >> we continue to have a long list of concerns with iran and their behavior. awe as you point out they have a record of supporting terrorist organizations around the world. they menace our closest ally in the middle east, israel, and they're unjustly detaining u.s.

citizens inside of iran. we have a list of concerns, all the more reason to make sure that they do not obtain a nuclear weapon. >> isn't that why so many are concern about this deal, and is it worth risking further damaging relations with israel. >> the united states and israel have an unshakeable relationship. and unshakeable commitment to our mutual security. >> white house press secretary josh earnest. despite his assurances, many republicans and some democrats in congress are worried about this deal. on the heels of visiting israel, republican house spoker john speaker john boehner called the deal alarming: a day of mourning in kenya after a al-shabab massacre at

an university. many were remembering the 157 people killed in the assault. most of them were christian. they're still trying to identify all the victims. it's the bloodiest attack on kenyan soil since the embassy bombing. >> here at the gate of the garissa university, there have been people coming in and out and collecting the boyd of the deceased. and then students were allowed to come back and collect their possessions. and then we a vehicles from the american embassy going in with what looked like security operatives inside. they are possibly assisting with the forensic investigation going on there. people just heard a short while ago from a security source that four assists have been made in connection with the attack. two of those arrested are kenyan and the other two are of

different nationality. here in garissa people are trying to come to terms with what happened, and why they were left so vulnerable with so little security here before the attack. >> mall some webb, thank you. officials say they have arrested a philadelphia woman for allegedly trying to join isil. she was posting messages on twitter offering to be a martyr for the group. authorities say she bought a plane ticket to spain last week and they say she was researching how to get from bars loan barcelona to istanbul. now to yemen where they're pushing more foreign nationals to flee the country. a chinese naval ship took 176 pakistanis from the southern port city of aden. they arrived in islamabad today. and russia says that more than 300 people from eastern european countries have arrived safely. saudi officials is a that i 12 houthi fighters were killed in

battles at the aden airplane. it comes after houthi fighters withdraw from the presidential palace in the port city. we have more on this latest development. >> fighting raged all night as saudi-led coalition jets bombed houthies and their allies. meanwhile the so-called popular committees loyal to president abd rabbuh mansur hadi are also engaged in street battles in aden. saudi tv says that the number of airstrikes forced the rebels and forced those loyal to former president ali abdullah saleh to give up the presidential palace just a day after they captureed it. >> aden is a peninsula and these people are blocked.

the unfortunate things, they're really hitting civilians from the tops of the hills where they're remaining there. >> but despite the ninth day of the aerials they're still fighting back the saudis could be using another tactic to come bat the houthis. these pictures show boxes of weapons and ammunition dropped by syrian-led coalition jets into the city. the battle could be a long one and the number of casualties continue to grow. the u.s. said it is concerned. >> i call on all parties involved to make their obligations under international law and do their utmost to take the ordinary women children and men. reports from humanitarian partners from different parts of the country indicate that some

519 people have been killed and nearly 1700 injured. >> millions of yemenis remain stranded. al jazeera. >> u.s. defense secretary ash carter is preparing for a major trip to asia. he leaves monday to visit with military leaders in japan and south korea. carter's visit comes ahead of chinese prime minister shinzo abe's visit to washington at the end of this month. march was not as good as many hoped when it came to job growth. 128,000 jobs were added last month. thisunemployment remains steady at 5.5%, and the labor force participation rate is 62.7%. analysts blame bad weather and reduction in hiring reflected by falling oil prices. cal's drought is taking a hard toll on the state's

agriculture industry, and water restrictions could mean even tougher years ahead. >> part of al jazeera america's >> special month long evironmental focus fragile planet

>> we're learning more about the final moments of the germanwings plane that crashed in france. information shows that co-pilot andreas lubitz deliberately accelerated the jet as it descended into the french alps. all on the plane were killed. the crippleing drought in california farmers are worried about the future of their crops. >> on a small organic farm in camarillo north of los angeles phil knows what it feels like to live with less water. >> farming organically is already a trick. but farming without water that's a big trick. >> is that what you're having to do? >> that's what we've been doing the last few years. >> he has been farming this land for the past 37 years and has seen it all wet years dry years, but nothing like the last three years.

>> we just haven't had any rain. it's just more insects. the cost of water is three times higher than it was three years ago. it's only going to get more expensive. >> we first met mcgrath a year ago. at that time the drought was a concern. now it's a crisis. governor brown's unprecedented water restrictions stop short of placing further restrictions on farmers, but does require them to submit a detail drought management plan including how much water they currently use. farms big and small have already seen large cuts to the amount of water they're allocated for irrigation and when you consider 80% of california's water goes to farms across the state, it's possible even larger reductions could come in the future. >> as californians we have to save water in every way we possibly can and we have to pull together. there will be some heartache here. >> the governor's order for now targets mostly city dwellers who

use more than their fair share of water from keeping cars green toclean and yards green. >> what is the water that we're seeing here in the creek? >> we haven't had any rain in a while. it's a weather run off that basically comes from the streets and storm drains from people watering their lawns. >> an advocacy group working to protect and restore local water supplies. although the group applauds the executive order they wonder why it took so long? >> should the governor have acted with restrictions earlier. >> we've advocateed for restrictions long before now. i do believe there has been a lost opportunity over the last year since the government

declared a drought. it took a long time for californians to realize that we're in a dire situation and i would say that there are a lot of "kens" who don't realize it. >> governor brown's executive order expands on restrictions already in place. since last july residents were limited to lawn watering to two days a week and can only water cars with shut off nozzled. good first steps? absolutely, but the law needs to be done now. >> we would like to see state agencies put a limit on how many gallons per capita per day can be used in california. that should be based on current usage. not only should there be a reduction statewide but we should look at it and ensure that they're making the biggest reduction so we have an equitable distribution of water among the states. >> a shared sacrifice that will cause heartache as the golden state continues to turn brown.

>> there is a potential solution in the works for california's water problems, and similar challenges around the world. aztec know's phil torres and dr. samara report one company is taking waste water and turning it into clean drinking water using only the sun. >> underground drainage water. northerly occur ohing salts and other heavy metals makes this water unfit for irrigation or human consumption. >> this is what we call sub surface tile water. historically this water has been problematic water. our goal is to take this water and turn it into a productive resource. >> so this water actually runs underground about eight feet, and you brought it up to the surface. you're going clean it up, and then attack it back to the crops. >> that's the plan. >> aaron mandel is ceo and founder of water fx, the company behind the desalination plant. it's prominent feature is this,

377-foot long mirrors. >> we're using large mirrors here to capture the heat. >> mineral oil travels down the central tube and is heated up by the sun to 248 degrees. the heat is then piped into evaporators and the steam is generated. fresh water is condensed from the steam and salt and other minerals are removed in the process. >> what percentage of the water is purified? >> we can go to 93% water recovery. >> is 93% typical amount of recovery? >> no, it's not. it's very high. that's what makes this process different from traditional seawater desalination. >> this is very clear. but more importantly doesn't have any salt in it. >> okay, i'll taste it. >> how does it taste?

>> it tastes very earthy. >> that's the whole point of the process. we can make clean drinking water with just using the sun. >> when it's complete they athey'll be able to process 2 million gallons of fresh water. >> one of our biggest challenges is just getting farmers to think that he desalination could be a reliable source of water. >> we need to start looking at water treatment as an additional water supply for the state of california and the world. water is going to be our future gold. >> you can watch techno today and every friday. it's 4:00 p.m. eastern time. 1:00 p.m. pacific. authorities in mexico are urging residents to stay away from a dangerous volcano. the volcano has been erupting in the south part of the country not far from guadalajara. it sent up a thick column of ash two miles into the air. there is little ash that has

spread very far but authorities are setting up a three-mile exclusion zone around the volcano. and also in mexico, new legislation has been designed to avoid cruelty to animals and applies to animals in circuses, and says that they should live in their habitat. >> it's a hammer blow to junior, who has been training big cats all his life. >> i'm going to be out of work along with many other trainers. our families have done this for generations. we are in shock. what are we going to do? >> this is where his tigers live live.

his animals live in small cages part of the push of the man. they released a slew of videos depicting animal cruelty. >> i think the circus has to evolve. for a long time they dressed up animals and they say it will bring job losses, but i think they'll need more people for new and bettering. >> the banned publicity has caused 70 circuses to close their doors for good says mexico's circus association. their animals are in limbo kept for now in ranches like this one with more and more arriving. these animals have been in storage for the last couple of months with the circus that owns them paying for their up keep, but that can't continue forever. the question is what will happen to them when the ban comes into full effect? >> they're going die. who is going to maintain them? unfortunately, the circuit people don't have the money to keep them. >> the government said it will look to zoos and sanctuaries to

take on the animals. but many don't have the space or resources for new arrivals. >> the relocation of the animals worries me because many are mutilated, clawless and toothless. they're not going to easily find good homes in zoos or sanctuaries, which don't have the infrastructure to care for them. >> the future remains unclear for both these animals and the circuses that will shortly be without their chief attractions. al jazeera. mexico city. >> next up on al jazeera america, as the christian faithful gather to mark friday, in china printing bibles even though the government does not officially recognize the religion.

>> it's one of the holiest days of the year for the christian faithful and hundreds of worshipers are gathered at the vatican to mark good friday. pope francis held mass inside

balance silica. in his sermon the pope honored the chinese government tolerates religious practice does not endorse it. despite that christianity is growing in popularity there. that's reported by the success of the bible printing company. there was a time when the little red book was the best seller hear but now there is another one, the bible. 13million printed last year alone. many exported but the majority were interior the domestic market. purchased for churches.

>> first if we still have the capacity we'll serve the overseas churches. >> the factory publishes bibles in nine languages from arabic to russian. such is the demand for the holy book it remains an around the clock operation. according to official figures around 30 million people are christian. unofficially it's 100 million. that's more members than the communist party has. whale religion is tolerated the government is wary of its growing popularity, a popularity reflected here. the factory began publishing bibles in 1987, just a few years before the communist party ended it's campaign to try to wipe out religion. today it's proof that there is money in religion. a contradiction that is perhaps only possible in today's china.

>> and in today's china more people are seeking meaning and piert actual comfort that neither communism nor capitalism seem to have supplied. we are always thinking the value of life. >> he believes 20 years from now there could be 160 million chinese christians, and of course they'll need a bible made here. adrian brown al jazeera. >> thanks for joining us. i'm libby casey in new york. the news continues next live from doha. remember you can go to our website for the latest news headlines. check out www.aljazeera.com.
