gained control of aiden pushing the shia rebels back and say houthis must surrender before the peace process can begin. >> translator: no talks at the present time as long as the houthis and militias of ali abdullah saleh continue the crime against people and until they put their weapons aside and surrender. >> according to u.n. agencies more than a thousand people have been killed since fighting began over a month ago and we have more on the deteriorating humanitarian situation. >> reporter: there is a semblance of law an order here despite no clear government earns in yemen a bomb disposal is at work hitting an air strike earlier in the week and spent ammunition liters the streets and lying around for days. >> translator: the area is not free of chemical substances with

detectors and connected explosives and being moved to be disarmed somewhere else. >> it was the loudest blast people heard since the saudi-led campaign began and look around and you have a sense of lost hours and thousands of dollars that are needed for reconstruction and the city's largest hospital is a 20-minute drive away. some of the most serious cases will be seen in its intensive care unit but according to the director that may not be the case for much longer. >> translator: electricity supply by the government has been cutoff we are using generators but there is not enough fuel this has been going on for a week and if it continues i'm afraid the hospital will have to close. >> reporter: this is not the only hospital in trouble.

the world health organization is warning that yemen's entire healthcare system is on the brink of collapse, the head of the red cross in sanaa believes keeping hospitals running is even more pressing than the need for food. >> if we don't find a quick solution now it will be a catastrophe in a few days. hundreds of people can die because they don't have medicine. >> reporter: while medical aid has started to arrive his staff face yet another pitfall. delivering them to the hospitals.

>> nigerians recently voted in a presidential election. religion ethnicity, and where you come from could but not always suggest how one votes. that's why john says his landlord kicked him out. he also escaped from boko haram. he thought this would be an easy transition. >> it doesn't matter who you think i volted for. why kick me out? it's my right. -- trying to calm tensions and teach people that ultimately

there is no excuse for intolerance. >> the personalities begin to create, like a cause and anything that happens to them they take it personal instead of taking it as just part of the game. >>reporter: yola is a vibrant and busy city. it's in one of three states still under a state of emergency because of boko haram attacks. a lot of people who have been displaced came here for safety so for now perhaps more than ever, this place is a mix of different religions, ethnicities, and political affiliations. but this is not home for these families. they look forward to going back home but say they cannot right now. they have been told the nigerian army has retaken many towns from

boko haram but they're still scared. armenians are marking 100 years since the massacre of their relatives and an ancestors. they are laying flowers in tribute to those who died. 1.5 million people were killed in what it and 20 other governments call the first genocide of the 20 century. turkey rejects the use of the word genocide. >>reporter: he watches his great, great grandchildren play. he was six when they left their farm in western armenia. his father was warned their farm would be targeted. >> my mother dressed as a kurd. my father has a mustache.

he told them he was a kurd. if they found out he was he was armenian, he would have been killed. when mothers got tired they couldn't carry their infants anymore and threw them in the river. that was better than leaving them on the ground where wild animals would eat them. >>reporter: eyewitness accounts are on display here at the armenian genocide museum. this new exhibition timed to open with the centennial celebration is the first time the mass killing of armenians is

shown in the world context. >> it's not only part of armenian history. it's a part of turkish history. >>reporter: armenian's president was one of the first visitors to the exhibition and says in addition to remembering the past armenia is also looking ahead. that's why it's not putting any preconditions for establishing relations with turkey. >> our position is fair and constructive. >>reporter: many are still demand body acknowledgment from turkey. >> they absolutely have to admit it. >> the wounds need to be healed. >>reporter: the church has canonize the victims of the mass killings as saints. the ceremony has not been seen for more than 400 years. armenia's message 100 years on

is that it's important to recognize what happened in the past and condemn it hoping tragedies like this are not repeated in the future. >> turkey has condemned vladimir putin for calling the massacre genocide. we have a report from istanbul on the huge sensitivityies that surround that world. >>reporter: he runs a small museum in istanbul. on display are artifacts, books, and memorabilia that belong to her late father a general in the ottoman army. it is his view of 1915 when thousands of kurds were allegedly killed by the ottoman turks. >> there is no problem between the turks and armenian people. the ottoman government told them you have to change place because

now you are with the russian people and you are killing us. we see that. we give them milk and doctors. >>reporter: according to the general's memoirs, it was the armenians who instigated the violence. >> my father's book says -- arms and the bodies on the ground. >>reporter: it's a stark contrast to what's become a common narrative. in the past month, both european parliament and catholic pope francis have described what took place 100 years ago as a genocide conducted against the armenians. and it is this word genocide that continues to anger turkey. while the government concedes that many armenians were killed it insists the term itself is totally incorrect. >> politically, we believe that that term is being exploited in a way instead of reading an

event in a just manner. technically it's also wrong because for the term to be applied, you need to have a systemic policy of extermination of all. we know there are armenians that -- we know there are part of -- >>reporter: despite the controversy under the premiership, the government issued a letter of condolence to the armenians for the first time ever in 2014. national pride is ex-tremendously prevalent in turkish society. there are huge flags flying high and draped across buildings. this sense of patriotism makes people very sensitive when discussing sensitive issues. >> turkey has never committed such crimes. >> it wasn't the turks who committed genocide. it was the armenians.

>>reporter: despite the opposing narratives and the tension it creates, there are still thousands of armenians living in turkey and are left to mark the anniversary freely. concerts are being held together with a church service in the main carcinoma cathedral. officials here say they're more interested in building a future with the armenians than focusing on the past. the german backed ottoman forces withheld an allied attack that is considered one of the bloodiest battles of the first world war still to come on the program, how rules designed to save lives forced businesses to close their doors in bangladesh. also, ma lair i can't break

"faultlines": death on the bakken shale. monday, 10:00 eastern. only on al jazeera america.

>> part of al jazeera america's >> special month long evironmental focus fragile planet welcome back to the news hour. reminder of the top stories here on al jazeera. the eu is to double emergency aid to countries on the front lines of the migrant crisis. more are being killed trying to cross the mediterranean sea this month than ever before. more air strikes in yemen as the saudi-led coalition targets houthi fighters >> and armenians mark 100 years since the massacre of their an ancestors during the first world war. al jazeera has met a group of migrants in paris who say the reality is a far cry from their

dreams. they are now living under a bridge. >>reporter: 50 migrants from mostly sudan live under a bridge made the hazardous journey across the sea from libya escaping war from home and hoping for a better life. none have papers and rely on charity for everything. it's a kind of migrant limbo. mohammed spent three years working in libya. he paid $1,100 for his place on a boat which made it to italy and now this. >> it's not the life we imagined finding in europe. we don't know what to do. but we are obliged to be here. this is the path we took. but i ask myself why are we here? the eu states don't seem to be interested in us anymore. >>reporter: those trying to help migrants in france say people like mohammed are victims of a system which is intentionally

slow and designed to discourage. >> the argument which is brought forward by the government is always that if you welcome them too well more will come and this is terrible because it's not true. people in sudan or syria don't think, oh i'm going to ask for asylum in france because i'll have a shelter. they only think i have to leave home. i cannot stay there otherwise i will die. >>reporter: this unprecedented surge in the number of people trying to reach europe unfortunately for them seems to be matched by a hardening of attitudes here in france to immigration as a whole. so finding the political will to help migrants settle more quickly and in greater numbers is going to be very hard. the rise of the national front in france is mirrored elsewhere in europe tempting politicians into ever-tougher posturing on immigration. add to that stagnating economies and soringeing -- out rather than

welcoming more in. the worry for these migrants now may not be how to get asylum but how to avoid being sent back to where their long journey began. police in italy have arrested nine people who have alleged links with al quaeda. prosecutors say the suspects were involved in a plot to attack the vatican five years ago. the attack was never carried out. all suspects are from pack stand and afghanistan. hundreds of garment factories have shut down in bangladesh this year. many can't meet the demands for better wages and new safety standards. >>reporter: it's been almost a year since the lights were turned off at fashionist garments.

shahid and his family began business only three years earlier. they were in a rush to get in on an industry that was expanding fast. propelled by some of the lowest wages in the world bangladesh has quickly become second only to china in exporting ready-made garments. but in april, 2014, a building collapsed which lead to better safety standards and higher wages. unable to meet the requirements he shut down operations. >> they did not give us a chance. >>reporter: in bangladesh not all garment factories are created equal. while many mid range operators

like fashionist are struggling to stay afloat or shutting down higher end factories are expecting business to pick up. the fashionist factory set a few hundred thousand dollars to set up. in contrast this is a multimillion dollars affair. the company has the resources to not only meet safety standards but also break the mold when it comes to the expectations. the more complex products were usually made elsewhere. but as the industry matures here, that's starting to change. >> so it is possible to also do very high volume work high value work low volume high value work. also in bangladesh a lot of factories including mine is changing our set up to handle this high margin business as well. and actually moving that

business and winning against china. >>reporter: shawn says the industry here is undergoing a shift with consolidation at the top that's creating more orders for owners like him. the flip side is the weeding out at the bottom spelling the end for some local operations that can no longer keep up. one of south korea's biggest unions has organized a massive rally in seoul. it's the beginning of a strike expected to continue for another week. some workers are angry after the government cut pension benefits and made it easier for companies to fire employees. unions are calling for better working conditions and they want the government to increase the average hourly wage now, fighters say they are closer than ever to finding a successful vaccine for malaria. it affects about 200 million

people every year. most are in africa and many are children who don't survive. we have more on a new vaccine which could reduce cases by 30%. >>reporter: a few tears of pain for a few years of partial protection against malaria. in sub saharan africa 1,300 children die every day from the disease. there's never been a licensed vaccine. but for almost 20 years, a research team based in africa has been working towards one. now their biggest trial of what's known as the rtss vaccine involving 15,000 infants across seven countries over five years has delivered its results. >> this shows that this vaccine has some impact over a four-year period. it reduces clinical attacks of

malaria by 30%. >>reporter: is 30% enough? >> no we'd like it to be 90% but it's such a big problem that if you can reduce it by 30%, that's a huge saving in childhood deaths. >>reporter: brian greenwood has devoted 50 years to fighting malaria. he's thrilled control measures already in place are working. the latest world health organization malaria reports reveals a 47% drop in deaths across the globe in the last decade. in africa the mortality rate has decreased by 54% in the same period. >> we're not suggesting it's a replacement for other measures like bed nets. the consideration would be is it worth while and cost effective to add this on to the other measures that are already being given. >>reporter: the world health organization will decide whether to recommend the vaccine for use by the end of the year.

he is head of research at the health research center and a lead researcher of that vaccine trial. thank you for being with us. in your view how significant a break through is this in terms of actually saving lives? >> well this is a significant scientific improvement in terms of public health we think that this initial step to malaria development and this is one that we think would save significant lives. >> can it actually be improved and tweaked before it actually goes on general marketing do you think or is it going to go out to the public as it were in its current state? >> well currently the data that we have has been given to the

authorities and they will decide whether it should go onto the market or not and of course the world health organization as a scientist, we have just provided data. other scientists could look at improving it and also making it for efficacious than this. >> who actually pays for it? how does the money side of things work out? >> well the money side of this i don't know how much it's going to cost but what i know is that the manufacturers of the vaccines have suggested that they are committed to ensuring that they would produce the vaccine at low cost profits and also just about 5% overheads. what we're looking for is for the vaccine to be made available to children in africa at not

cost. just as the others. >> 30% reduction in cases which is what you hope this vaccine can achieve is a great achievement given there's not a viable vaccine around at the moment. but why is it proving so difficult to find a vaccine for malaria because scientists have been trying for decades now. >> this is a challenge. this is a parasite and the parasite seems to change quite often and that is why we have not been able to develop a vaccine against this parasite. and that's one of the excitements about the malaria vaccine trial now. this is the first human parasite vaccine that has reached this stage of development and it's exciting. it can be improved. and obviously hope it will do so. >> wish you the very best with it. thank you so much. >> thank you very much. now, here is a trivia question for you.

which country produces the most downloaded mobile phone apps in the united states? well the answer might surprise you because it's argentina which is home to the hugely popular quiz game trivia crack. >>reporter: what is the capital of bolivia, who won the most best actor oscars oscars. who would have thought general knowledge would be so much fun. >> we tend to think kids don't want to learn. that's not true. the way they learn at this point in this history is the same way that they did 100 years before. >>reporter: the 29-year-old founded it while still at university providing apps for the financial world. his latest game took latin america by storm a couple of years ago. approved of by parents and

teachers alike for its educational content. trivia crack questions are updated, discarded, and added daily. supplied by the users and made for each country. it's been the number one app in 22 countries in 11 languages. >> the future of it -- we could be doing our job in tokyo or madrid or here. the thing is gathering a group knowing where to go and just experimenting and learning and seeing how to be the best in the world. >>reporter: now, the company that produces the number one app in the world with 125 million downloads so far, 750,000 new ones per day is not in silicone valley and not even in a shiny new building in the heart of the capital city here.

this is it. this warehouse in a residential warehouse. it's the company his father wanted him to inherit. his son is occupying ever more space now employeeing 95 staff from around the world but not in the way his father had imagined. >> it's a huge industry and it has very easy access to distribution to markets all over the world. argentina has a lack of an internal market unlike the united states and so their focus has to be in bringing things out to other countries to be english-speaking market in particular which is dominated by the united states. >>reporter: and all this while argentina's economy is in recession with rapid inflation and many leaving to work abroad. so what letter represents iron on the periodic table? easy. oh dear maybe not so easy.

history and the archeological study is revealing much about the its early beginnings. >>reporter: skeletons of romans living in london 2,000 years ago found in a tiny square of europe's largest construction project. experts are not sure how the skulls ended up here. possibly washed up in an ancient river or slain gladiators from a nearby arena. over the last few months archeologists have doneug down six meters. they found victorian houses and then found a massive burial ground. >> we worked our way down from if 16th and 17th centuries in london through the medieval period the post roman period where the area was a huge area of marsh. down to where we are now at the roman level, pretty much roman

street level 1,900 years ago. >>reporter: once the bones and tools and bits of leather and coins are carefully unearthed from the site they're taken to the museum of london archeology labs where scientists there further study and catalog them and learn all sorts of things about history. each skeleton goes through the processing protocol. after pressure washing, they're put in a drying room for a few days and then cataloged. because the cemetery yielded so many skeletons, more than 3,000, there are plenty of samples to look out to figure out how people lived and died in 1569. >> people who may have died from the plague and look at the pathogen itself from their teeth. >>reporter: jewelry, coins, and thousands of disposable clay
