i knew that we were right. i think that it is a good i think that it is a good system. -- captions by vitac -- www.vitac.com brief -- germanwings' co-pilot andreas lubitz may have hidden a medical condition. leaders discussing what's next for yemen. he saved my life, and i'm so grateful. and i -- i'm so grateful to have my life back. >> amanda knox overcome with emotion after italy's high court overturn the her murder conviction. welcome to our viewers in the u.s. and around the world, i'm natalie allen. this is "cnn newsroom." we begin with new

revelations about the co-pilot of germanwings flight 9525. "the new york times" and "wall street journal" are reporting citing unnamed sources that andreas lubitz suffered from mental illness. the reports go on to say he hid that from his employer and parent company, lufthanza. police have been scouring the co-pilot's apartment in dusseldorf for more clues into his past. friday they carried out boxes of paper and evidence folders. for the latest on the investigation, i want to bring in cnn senior national correspondent, fred plight good friend -- pleitgen, from germany. the more we're learning, the more troubling this scenario becomes. >> reporter: yeah, absolutely, natalie. it's no question to the german investigators and french investigators that he was hiding an illness from his employer. keep in mind the german authorities have been searching his apartment, both the one in dusseldorf as well as the one he

had where he lived with his parents as well as his brother. the medical records that they found appear to have been found in the dusseldorf apartment. and those indicated showed that he was receiving treatment for an illness. this of a long-term illness. the other thing, he was deemed by his doctor to be unfit to fly for the day of the flight when he crashed the plane into the french app. there was a sick note that was found inside the apartment. it was torn up. and that, they say, strongly shows that he was trying to hide this illness from his employer. the big question, what kind of illness was this. the german investigators haven't said anything about it or specify what sort of illness this was. the new york time and other publications reporting this was a mental illness. it is unclear. we got in touch yesterday with the university clinic in the town of dusseldorf, one of the places why he had an apartment. they said that, yes, he was

there for diagnostics, but they did not say for what. they said it wasn't for depression. could this have been for some other mental illness? did he have other illnesses? it's unclear at this point in time. there are report throughout with "the new york times," publications, german publication, as well, that say he was suffering from depression. it is certainly something that we're going to be looking into, that investigators are looking into, as well. as this investigation goes forward, of course, they're questioning a lot of the people that he knew, foremost, his family, parents, brother, and people that he would have had contact with. there's talk of him having had a girlfriend. obviously he was other friend and his colleagues at germanwings also. >> yes, and you interviewed the ceo of lufthanza, fred, before these revelations were reported. he gave such a sincere and

honest account of the reputation of lufthanza and did not seem to have an inkling about this pilot. has there been any reaction from the tyler these reports? >> reporter: -- the airline to these reports? >> reporter: no -- so far the reaction that we've gotten has opinion one from brief directly. they said they can confirm that they did not ever receive a sick note from andreas lubitz. they say that that corroborates the findings of the german investigators. there's been very little statements otherwise. you're right, when we interviewed the ceo of lufthanza, he did say that he very much believes in the screening process. he says it's worked for the airline for many, many years, for many decades, and said it's not something that necessarily they would change in the future. he said in light of what happened, in light of the fact that apparently there was someone who for a very long time was hiding the fact that he had some sort of illness that in many ways made him unfit to fly, and no one here ever noticed it,

that is certainly something that now they say they'll look at all their processes and make changes. there's one change, of course, that they have made, which is more a change to the flying resumes themselves. they have also adopt -- flooi g i-- flying rules themselves. they have also adopted the rule that there's always two people inside the cockpit to prevent someone from locking themselves in, which is of course what happened in this case. >> i'll talk with an aviation expert about that change this they've announced in a moment. fred pleitgen in germany, thank you. at the scorched mountainside where the plane crashed, recovery teams say they are making good progress. that's according to the official coordinating helicopter operations in the french alps. you see how precarious the operations are as remains are removed there, airlifted to rescue aircraft. more will be deployed to the

scene today. officials say it could be week before all remain are recovered, identified, and released to family. cnn has this report from near the crash site. >> reporter: swinging on a wire, they recover the remains. hundreds of feet below, emergency crews cling to the mountainside, just so they don't fall. investigators say the speed of the crash pulverized plane and passengers. the recovery operation, they say, is bit by bit, bag by bag. you can just pick out the small red flags rescuers dig to the earth when they discover new fragments. and that looks like a scorch mark. the french prosecutor said the plane hit the mountain, bounced off, and then disintdisintegrat. it's a tough hike through mountain and valleys.

it's a little while before dawn, but we're going to a trailhead in order to understand some rescuers describe in as their biggest ever challenge. we try to get closer to the crash zone. there's a little frost this morning. now the sun's coming down. certainly no sign of snow just y yet. "few people except shepherds live up here, continues are too inhospitable." getting here is literally hanging on to tree roots and grass. can see why they have to fly anything out of the crash site by helicopter. the whir of rotor blades helps pinpoint the site. from our vantage point we see forensic teams working with expert mountaineers to keep them safe. high sprinwinds make flying treacherous. saying farewell is never easy.

perhaps those grieving could find a little consslation amid these crags. piece of the running water, piece of the snow-capped peaks. peace to loved ones lost. cnn, the french alps. we'll have a live report on the search there from the scene of the crash in a few minutes. as we mentioned, lufthanza and other german airlines have announced pilots will no longer be allowed to be in the cockpit alone following this disaster. for analysis, let's turn to t tomba tomballentine, he has years of experience covering the airline industry. i would like to ask you if it's indeed accurate, this co-pilot had health issues, perhaps

mental health issue, how unusual that a co-pilot would try to hide something so serious and that he could hide this from his employer. >> of course, it is very unusual for this to happen. it's quite shocking. the fact is that pilots are highly paid professionals, highly trained and retrained, getting regular health check. when you get to the bottom line, they're exactly the same as you and i. i mean, they have a life outside the cockpit, the stresses and strains that people go through during their normal life. with the tens of thousands of pilots flying around the world, it's not surprising that once in a while a case pops up like this where someone is able to hide their feelings, fool their employers, and into something like this. >> it should be comforting to people to hear that these pilots are very carefully monitored every six months. they must see a flight doctor.

is that correct? >> reporter: well, it's not entirely correct. i mean, one of the great issues of the global airline industry is the lack of standardization. there are no globally standard rules for pilot training. no rules across the world for the amount of hours they're allowed to fly each day. there are no rules to say they must have a health check every six months. varies from country to country, sometime from airline to airline. if you take the retirement age of pilots, some country, it's 65. some countries it's 67. new zealand, in fact, has no retirement age for pilots as long as they pass the health checks. they can keep on flying. getting these standards all around the world, particularly in this area of health and mental health is something that really needs to be looked at. >> perhaps it will. pilot suicide has occurred, of course, but rarely it's

suspected in the mh370 mystery. will the two person in the cockpit rule that we're seeing take hold now in more airlines, will that help make flying safer or just help people perhaps feel safer? >> it may help in some cases, but there's diverging views within the industry. you know, you have a pilot go to the toilet, a flight attendant goes into the cockpit. the fact is that someone who is determined to crash an airplane, a trained pilot, a flight attendant may not be able to stop them in the end if the person puts the aircraft interest a steep dive. what will the flight attendant do? i don't think it would totally solve the problem in every case. >> we appreciate you joining us. tom ballentine, appreciate it. in other news, amanda knox says she is incredibly grateful

that her eight-year battle again murder charge is over at last. italy's supreme court friday threw out murder convictions against her and her former boyfriend, raffaele sollecito. the pair were tried, convicted, and eventually acquitted for the stabbing death in 2007 of knock' roommate, seen her, meredith -- knox' roommate, seen here, meredith kercher. she was sentenced then to more than 28 years in prison. knox spoke with reporters outside her home in seattle, washington, after learning this was finally over. >> i don't want to answer questions. i just wanted to say that i'm incredibly grateful for what has happened, for the justice i've received, for the support that i've had from everyone from my family, friends, to strangers, to people like you.

you saved my life, and i'm so grateful. and i -- i'm so grateful to have my life back. thank you, and -- that's all i can say. right now i'm still absorbing what all of this means. and what -- what comes to mind is my gratitude for the life that's been given to me. >> what does the future hold for you now? >> i don't know. i'm still absorbing the present moment which is full of joy. thank you. >> thank you very much. >> other than, again, we're so grateful. i know that you're all here. but we really need time as a family to kind of digest and, again, so thankful that everything is finally right.

[ inaudible ] >> meredith was my friend. and it's -- she deserved so much in this life. i'm the lucky one. so thank you. >> emotional, amanda knox replying to a question whether she had a message for the victim, meredith kercher's, family. again, the case now is closed for good. air strikes pound yemen for a second straight day. next, the country's u.s.-backed president heads to egypt. will he find a way to resolve the crisis?

a saudi-led coalition targeted locations in yemen in an attempt to drive out houthi rebels who have overthrown the government. the rebels attacked two tv stations in the capital of sena. al jazeera says their cameras were stolen and other equipment damaged, but it appears no one was hurt. the failed state's president is in egypt for an arab league summit which will focus on the saudi-led campaign. egypt is one of the countries pledging its support to the coalition, and leaders from a number of arab nations have gathered there to discuss what

happens next. cnn's becky anderson joins me now live from where those talks were taking place. and becky, with talks of what happens next, that is a loaded question in this troubling scenario in yemen. >> reporter: that's right. and ground troops, the specter of ground troops will be concerning to the international community who will be watching what happens here. the president, as you pointed out, has arrived here to the red sea resort town for the summit of arab leaders with the crisis in yemen front and center. now egypt's president will open things shortly. and by close of play tomorrow, sunday, weship expect a resolution -- we should expect a resolution in support of the saudi-led offensive targeting houthi rebel backed by riyadh's regional rival, iran. that resolution could be wider at this stage, as well.

looking to an arab military force for the future. now the saudis are calling this determination storm. they've been targeting locations in north and south yemen over the past 24 hours. we know particularly the land along the saudi poureder where they say houthi rebels were mobilizing. any resolution here will give the green light for further concerted arab action. this could be no small war. it has to be said, riyadh deeply concerned about the area along what is the 2,000-kilometer border with yemen, becoming an iranian stronghold threatening its eastern province where the kingdom's rich oil deposit lie. the uae over the past couple of hours has confirmed it has been actively involved in the air alongside saudi. and egypt's foreign minister confirming to me that if needed,

cairo is prepared to offer ground troops to this coalition of the arab willing intent. of course, on returning stability to a country in chaos. now, here is the nuance, of course. iran has strongly condemned what they call a saudi invasion of yemen saying that its continuation more likely than not to provide further opportunities on the ground for terrorism and extremism. remember, we've witnessed these deadly acts of violence by both al qaeda and isis over the past few weeks. and this, of course, comes at a very, very sensitive time as a u.s. -- the u.s. secretary of state john kerry and his iranian counterpart are desperately trying to hammer out a deal to bring tehran in out of the cold. now sources here saying that while the u.s. is not concerned that this current uptick in rhetoric between saudi and iran on yemen is going to affect those talks, those same sources

they there is a sense that the saudis are impatient with the situation on the ground in yemen. and that could risk alienating other long-time partners in the west. so it's very, very important what is going on in yemen at the moment. what goes on in yemen doesn't stay in yemen. clearly at this point. but you will see a concerted effort here by all 22 arab leaders who are gathered to really bring sense to the idea that when there is an arab war that the arab leaders get together and fight this themselves. i spoke to the egyptian foreign minister last night. just a very quick sense for you and our viewers of what he told me. what's your one message for the international community and in washington from this arab league summit? >> it is that the arab world is

-- has a desire to show solidarity, and its ability to undertake its responsibilities and meet the challenge of the region through arab solutions. >> reporter: that was the egyptian foreign minister speaking to me late on yesterday evening, as i say. the president hosting these talks. he is expecting to speak shortly. more on that as we get it, of course. pew. >> all right. thank you very much. another powder keg country that must be having people very nervous in this region that has been just tormented by war. thank you, becky. a controversial new law in a u.s. state has some people seeing red. why opponents of a religious freedom law say it will actually be used for discrimination. you forgot the milk! that's lactaid®. right. 100% real milk, just without the lactose.

so you can drink all you want... ...with no discomfort? exactly. here, try some... mmm, it is real milk. see? delicious. hoof bump! oh. right here girl, boom! lactaid®. 100% real milk. no discomfort. and for a tasty snack that's 100% real dairy, try lactaid® cottage cheese.

a new religious freedom law in the u.s. state of indiana has some of the company's largest company and civil rights groups upset. businesses can now deny services for religious reasons. opponents say the law could discriminate against the guy community, as shasta darlington report. >> reporter: opponents shout out their frustration. [ applause ] >> reporter: supporters applaud as indiana governor mike pence

sign to law that allows businesses to turn away gay and lesbian customers and the governor says will uphold religious freedom. >> this bill is not it discrimination. if i thought it legalized discrimination in any way, i would have vetoed it. >> reporter: the backlash fast and furious. the ncaa which is holding its mens basketball final four in indianapolis next weekend saying it's concerned about the impact on players and employees and warns it's going to rethink future events. openly guy nba player jason collins tweeted, "is it going to be legal for someone to discriminate against me and others when we come to the final four?" ceos from apple to yep denounced the bill and said it could affect business. the law points to bakeries that refused to make wedding cake for guy couples and were found guilty of discrimination saying now indiana businesses could turn away guy customers on religious grounds -- gay customers on religious grounds. the governor insists it couldn't be used that way.

>> this legislation restricts government action. it doesn't apply to disputes between private parties unless government action is involved. >> reporter: last year arizona republican governor jan brewer vetoed a similar bill amid threats to boycott the super bowl being held there. other states have similar life. but gay rights activists say the indiana law is one of the most sweeping. and reaction could impact whether other states take up the cause. shasta darlington, cnn, new york. search crews should be back on the job any time now in the french alps. we'll go live near the germanwings crash site for the latest on what they are finding coming up. also, nigerians voting for president today after weeks of delays. live in the country's biggest city in a moment. does your carpet ever feel rough and dirty?

welcome back to our viewers in the united states and around the world. you're watching "cnn newsroom," i'm natalie allen with our top stories. a german prosecutor says the co-pilot suspected of deliberately crashing germanwings flight 9525 was ill and hid that from the airline. he says investigators found torn-up medical notes in the home of andreas lubitz including one there a doctor declaring him unfit for work on the day of the crash. american amanda knox says she is incredibly grateful. late friday italy's supreme court reversed the second murder convictions against knox and her former boyfriend in the stabbing death of her roommate, meredith

kercher. the court's ruling bring an end to the eight-year sensational case. talks between iran and six world powers have reached a critical point. tuesday the deadline for a framework group on the nuclear program. centrifuge research and nuclear fuel enrichment remain the most difficult issues. it has been a slow and painstaking recovery process at the site of the germanwings plane crash. rescue operations are set to resume for the day soon. erin mclachlan live from where the plane went down in the alps. it has difficult for rescue workers. how are conditions today? >> reporter: authorities say they have so far made good progress in those recovery efforts, and they're expected to continue today. although we have yet to see the

first choppers of the day arrive here at the staging area behind me. a slightly scaled back operation expected today. authority saying some two choppers will be in the skies as passesed to the five that we saw yesterday. and as you say, this is a challenging and painstaking process. the locate of this crash site is extremely remote. accessible for now only by air, though authority say they are going to try and build a road to the crash site so that there could be a vehicle access. and the area there is treacherous, posing some safety concerns to investigator. it's incredibly steep. each investigator, therefore, having to be paired with either a police officer, a firefighter, mountaineering expert, someone responsible for ensuring their safety, they're tethered to each other, and really the priorities of the teams at this point are twofold. to recover the other black box, the flight data recorder,

they've managed to find the casing but have yet to find the card. they hope that that will give them more clues as to how the plane was being flown moments before it crashed. and they're also, of course, looking for the human reminutes. authorities saying the crash impact was so devastating, not a single whole body has been found. that search is -- is a grim one. and we're learning new details about the process. they have split up the wreckage into sections because it's spread over hundreds of meters. when they find a human remain, they attach a number and chart it so they know where everything was found. from there, they load the remains into bags and then airlift them out, eventually brought to a dna center not far from here for comparative analysis. we know that they have begun the process, the horrifying process really of collecting dna from

the family members. it must be so difficult for them. that compare sieve analysis expected to last weeks. the recovery process itself, though, they hope if the weather holds should be completed within 10 to 15 days. >> that certainly illustrates the difficulty of this effort in that video that we're showing now of these workers on their hands and feet just scraping the ground for anything. it's terribly upsetting to even think about. and we know that the families have been brought to the region, so they can even look to the mountains to fry and have -- to try and have peace with what happened to their family members. how many have come there, they staying, are more arriving, have they gone back to wait for word? what's the latest on that part of this? >> reporter: we know that today

they're opening up a new family center in marseilles. that being opened up by germanwings, about two to three hours' drive away from here. they're expecting the first of the family briefings to take place today. i'm realized -- authorities of germanwings saying that their priority is to inform and take care of the psychological needs of the families. the families, of course, are still welcome here in the french alps. several centers have been set up. locals opening their homes. there's a small memorial not far from here with a plaque dedicated to the families of the victims stopping to lay flowers and grieve. french president hollande said the priority in france is to understand what happened. he said that we owe that to the family, and certainly that sentiment is echoed in the efforts that we're seeing in the french alps today. >> we certainly hope they can build that road to the crash

site because just lifting these workers just one by one it the helicopter seems like it will take forever. thank you very much. cnn went inside a flight simulator to find out how the cockpit may have looked and sounded just minutes before the flight crashed. the pilot who provided our demonstration says what andreas lubitz did defies comprehension and goes against every instinct of a pilot. we get more if cnn's kyung lah. locked the physical lock on the door. ic that to lock, it will totally lock out that door. >> reporter: so begins what is the likely descent of the germanwings flight. we're in a simulator with pilot budge roger who currently flies for a commercial airline. >> you dialed in an altitude here and got the airplane going down. >> reporter: this motion of hitting 100 in this situation is

unthinkable for you. >> absolutely. why would i do that? it goes against every grain in my body. there's no reason why i would do that. >> reporter: you know the consequences of that action. >> absolutely. >> reporter: if you had to step in this young man's mind, do you think he understood? >> i mean, it's a very difficult subject for a pilot. we are, again, here to keep our passengers safe. to keep our airplane safe and the crew safe. to go where this young man went, it's hard for me to go there. by saying i'm fit to fly, that mean i'm good to go. i'm ready to take on this airplane. >> reporter: and all the legislative days in the back. >> that's right. >> reporter: approximately nine minutes later -- [ siren ] >> pull up! terrain! terrain! ? we would pull up and react. >> pull up! pull up! >> yeah. this is not a situation i've ever been in. >> pull up! >> reporter: what's happening to your hands after that crash? >> they're sweaty. and you can see it.

in all the years i've been flying in a simulator, i've never seen an airplane hit the ground. we recover before that happens. >> reporter: so that was unthinkable for you? >> yeah. hard to see. >> reporter: roger takes us through a manual scenario, explaining the germanwings pilot likely did not do this based on the controlled descent. >> pull up! >> reporter: uncomfortable. >> it is. let's just -- can we come out of this? >> pull up! >> get out of this. no need to take it through the -- >> pull up! >> reporter: even in the simulator, in a scenario we've asked him to do for the purposes of the story, this pilot cannot stand it. does it exceed pilot instinct? is it human instinct to pull up the stick at that point? >> yes. i'm thinking about the safety of my passengers, crew, and attendants. >> reporter: is that why the incident has so disturbed the

people in your profession? >> it's unthinkable that a pilot would take a plane and drive it into the ground. it's not something we think about. >> reporter: cnn, las vegas. >> we appreciate him helping us with the scenario. and -- certainly understand where that pilot had trouble even re-enacting that germanwings final nine minutes. the crash has reill nighted the debate over video camera inside commercial airline cockpits. randi kaye look at the argument for and against it. >> reporter: a 3,000-foot tumble from the sky. that's what happened to this cessna plane carrying nine people. >> it's very obvious that the aircraft path was near vertical. >> reporter: why this plane dropped straight down killing everyone on board back in 1997 baffled the ntsb. no black boxes were recovered, prompting investigators to call for cockpit video cameras. now nearly two decades later, we may be closer than ever to

putting cameras on commercial airplane. this is what they might capture in the cockpit. california-based physical optics corporation has already delivered dozens of cameras though none to major airlines. >> have a camera facing the door to the pilots. you could is a camera behind the pilots. depending on the type of lens chosen for the camera, you could have wide field of view, narrow field of view. >> reporter: the cameras are designed to focus on the instruments, on the pilots' hands, even their feet. not necessarily on the pilots' faces. they can record up to 32 hours. and the company says they can survive a crash, withstanding heat up to 2,000 degrees fahrenheit. >> it also will stand a 5,000-pound static crush load. >> reporter: just like black boxes, the camera is a beacon that lasts up to 90 days. allowing time to locate them. >> you can actually see when people took actions, and what switches they took, what the

settings were. you know, where you can -- you can read that through the flight data recorder to some degree. >> reporter: still, not everyone's sold. >> i'm very much against it. i just feel like we have pretty much the situation covered between a cockpit voice recorder which records every sound of any kind. >> reporter: concerned pilot argue it's nan invasion of privacy suggesting conversation about a supervisor or argument with a spouse could end up on youtube. still, the northeast argues cockpit cameras could -- the ntsb argues cockpit cameras could show what happens in the critical moments before a crash. did a pilot have a heart attack? was there motor vehicle some the cockpit? did a dangerous passenger manage to get inside? the airline pilots association reject the idea of cameras which could cost up to $ 100,000 each. the group told us resources should be focused on enhancing current systems as opposed to

video image which are subject to misinterpretation and may, in fact, lead investigators away from accurate conclusions. randi kaye, cnn, new york. we just learned from erin mclachlan there near the crash site the difficult conditions that these workers are working in there on that very steep terrain. derek van dam is joining us from the international weather center. in fact, she said normally there are five helicopters, just five. you know, trying to remove bits and pieces of the plane. and today there will be only two. >> reporter: yeah, it leads to the question what is that reason for the decrease in helicopter. the weather conditions across the area, which you saw in erin's live shot a moment ago, sunny weather overhead. that doesn't mean that the wind isn't still a concern, especially across the ravines and crevasses in this mountainous part of southeastern france. on the latest satellite loop

near the crash site, not much taking place in terms of weather. there's a weak cold front dropping south across france. it is going to help settle in a bit of cloud. we think the precipitation will stay just to the north of this particular region. the showers really located across germany and to the central and northern sections of fran and spreading across the u.k., as well. in fact, our high resolution forecast imagery going forward. you see the rain and snow line just north of where the crash site is actually located. nonetheless, we're still monitoring the possibility of winds gusting over 50 kilometers per hour which will make for difficult flight conditions for the helicopter crews. sunday's forecast, partly cloudy, increasing winds especially in the evening. another breezy day expected on monday late day showers expected by tuesday as this receivery effort goes forward. we have a break with the winds at the moment. we expect them again to pick up. you see the dark shading of red, and that's indicating wind gusts in excess of 60 kilometers per hour. a lot of our attention has been

on the recovery site efforts and the weather around that particular region. there has been other devastating weather that's taken place on the other side of the world. this being in chile. a particularly dry part of the world typically. but they have been dealing with 80-year floods across this part of central chilly chile. -- central chile. look at this video, astounding stuff. rivers bursting their banks. the government actually declared a state of emergency and sent in the army to bring in daughter and blanket to this region. this is taking place in a very remote part of central chile. it basically happened because rain filtered down the andes mountains and made its way toward the area closer to the coast. lots of stories to cover in the weather center. back to you. >> every day. all right. thanks. nay jeerns are ready to vote -- nigerians are ready to vote in a hotly contested presidential race.

a much-anticipated one after it was delayed. a look at why the election mean so much to so many. this is kevin returning to his childhood home. this is the smell of baked pears, making him feel warm. then pie crust, as he wonders if it's too soon to ask what's for dessert. now vanilla, reminding him of pep talks with mom and slightly inappropriate advice from dad. new air wick life scents in mom's baking, the first constantly changing fragrance that acts like real life and says 'welcome home, kev-y bear.' this is him, secretly loving the name kev-y bear. air wick home is in the air. but a lot of us leave our identities unprotected. nearly half a million cars were stolen in 2012. but for every car stolen, 34 people had their identities stolen. identity thieves can steal your money, damage your credit, and wreak havoc on your life. why risk it when you can help protect yourself from identity theft with one call to lifelock, a leader in identity theft protection?

former military leader. the polls don't close until the last registered voter casts their ballot. we have more from a polling station in lagos live. this is a day that has been anticipated for quite some time. >> reporter: it has. we're in front of a polling station, voting just getting underway. it is an extremely important election, not just for nigeria, not just for africa but for the world. it fits the incumbent president against the general. the reason this is important is nigeria's not just africa's most populous nation, it is also africa's largest oil producer. and you know, we have problems such as boko haram raging in the north. the hope is if nigeria can get a credible election, it will bring
