good evening, i'm antonio mora this is al jazeera america. after killing the organizers of paris attacks, people and clues and authorities are searching for the house votes for tough new rules for syrians entering the u.s., and concerns the families have, and the guarantee by president obama going home - why more mexican nationals have been leaving the u.s. than coming in

we begin with confirmation of the death of the suspected ringleader of the deadly attacks in paris. french prosecutors say abdelhamid abbaaoud was, indeed, killed in that raid on wednesday. still, the investigation into the attacks is far from over. al jazeera's dana lewis reports from paris. >> at what french authorities called a safe house. forensic experts hit pay dirt. in the northern paris suburb, a 7-hour siege played out with explosions and gun fire yesterday, the day revealed evidence that abdelhamid abbaaoud was neutralized. using skin samples, investigators determined abdelhamid abbaaoud, the master find of the bloody attacks, and his female cousin who detonated a security vest were dead.

eight more were arrested. a surprise for agencies that thought the belgium-born suspect was still in syria. >> translation: among the six attacks avoided or foiled by french intelligence services since spring 2016. abdelhamid abbaaoud was implicated in four. >> reporter: this was no ordinary crime scene. overnight police set up controlled explosives in the apartment. parts of building were collapsing as they tried to collect evidence. french intelligence can boast they have eliminated a key i.s.i.s. figure and in the end likely averted another major attack in paris. raids across france and belgium continue. in the search for suspects connected to an attack that claimed 129 lives and rattled europe. there are nagging security concerns. where is the bomb-maker who made at least eight identical explosive vests and where is salah abdeslam, involved in the

paris attacks, and disappeared after his brother blew himself up on friday. the government had little opposition to extend a state of emergency to three months. with seeping arrest and detention hours for the police. the prime minister warning of the unthinkable. >> we must not rule anything out. we mentioned yesterday, and we say we know and have in mind the risk from chemical and biological weapons. >> reporter: tonight the mayor told a crowd outside the stadium, where the first attack occurred. >> translation: we have learnt the leader of this barbaric attack is definitely dead, and we should all rejoice. [ singing ] >> reporter: but it's a difficult challenge. to restore confidence here, amidst growing fear. . >> it is now reported that abdelhamid abbaaoud came to

europe as an asylum seekers and did so three days before the attacks, making his wife through greece, and on to france. also, lots of questions as to why no other country alerted the french. he was on a terror watch lift. the leaders are meeting. the interior minister of france, bernard cazeneuve, will say europe, you have to transform the porous borders and control 5,000 jihadis that have been fighting in iraq and syria, control the borders, when some are coming back with an intent to carry out violence in europe. >> dana lewis in paris. lawmakers in paris took a step towards putting up barriers for iraqi refugees trying to enter the u.s. a rejection of the policemen by the president to give asil um to

those fleeing the syrian war. >> within a matter of days house republicans passed and blocked a bill allowing the refugees to come it the united states. there are steps to go through, but gives a sense of the move no congress and the move. >> reporter: debate on capitol hill over putting the syrian refugee programme on hole. >> if we stop the programme, we give i.s.i.s. a win. >> we lock our doors not because we hate the people on the outside, we lock our doors was we love the people inside. it would effectively halt the obama administration's programme to bring 10,000 syrian refugees to the united states over the next year. the white house promised to veto if the bill passes the senate, take the process is thorough. >> waiting 18-24 honth months,

going through a process of screening, interviews and vetting by the intelligence community is not at all the likely scenario by way i.s.i.l. carry out the attacks. speaker paul ryan says it's not just about lengthening the vetting process. >> i don't think time is the oib issue, it's quality. the issue is this is different because we don't have a syria to talk to or others on the other end to verify the voracity of the claims coming here. >> the bill calls for the programme to second until the heads of fbi, homeland security can certify that each refugee is demonstrate a threat. the inspector general for the department of homeland security would review certifications annually. it delays the process and puts people in harm's way out offering are offering layers of security. >> the refugee process has more

layers of security than any other programme allowing people in the united states. the republican bill offers no details of how federal authorities should improve the process, and there's no time line. many democrats want changes, like tightening the visa waiver programme allowing some europeans to visit the u.s. and want to ban people on a watch lift from buying guns, which were opposed and republicans did not include in their bill. >> the attorney weighed in calling the bill impractical and said vetting of each and every individual refugee is impossible. >> france now says it has destroyed three dozen i.s.i.l. targets since increasing air strikes after attacks. critics aft operation including some presidential candidates from both parties say air strikes are not enough, and the

fight will be won not in the air, but on the ground. jamie mcintyre looks at the fight against i.s.i.l. and how it's evolving. >> with russia and syria stepping up an aerial bombardment, there's a perception that the war is shifting into a higher gear. the reality is they accomplish little unless supporting troops on the ground. and the latest presents a mixed picture. >> reporter: the latest air strike shows france and russia hitting more targets in i.s.i.l. held territory. here they bomb trucks with pull that i.s.i.l. sells on the black market. without the leaflet drops the u.s. employs to warn civilians away. as a student of warfare nopes, area power has its limits.

it cannot take or hold territory. >> to be successful air strikes have to be involved with ground forces taking about territory. >> al jazeera obtained a military map assessing how the ground game is going. u.s. central commands i.s.i.l. lost 8700 or 40% of territory, up from 37%. the retaking of the iraqi town of sinjar by kurdish fighters was a ran i.s.i.l. locked ground. in syria it was a different story. in february i.s.i.l. lost 10%. the latest number is 770 square miles. that 770 lost territory or 5%, indicating i.s.i.l. gained ground as front lines were pushed back.

the assessment notes i.s.i.l. holds to cities in iraq and palmyra in syria. u.s. says its strikes have been calibrated. enabling troops to support against dug-in fighters. flushing them into et open. >> as indigenous friendly forces maneouver against the enemy, it causes them to move. they have to react. as soon as they react. we kill them in the air. >> reporter: the pentagon points to north-eastern syria where an offensive against syrian democratic forces drove i.s.i.l. out of some 280 miles and 200 small villages. the u.s. coalition supported 79 air strikes, which it says helped to kill 300. the idea of dispatching pore

u.s. special operations forces closer to the front lines, to provide advice. call in air strikes and increase coordination. president obama ordered up to 50 u.s. commando to syria. so far, they are yet to arrive jamie mcintyre at the pentagon. . >> five people, including an american israel were killed after they were opened fire in the west bank. earlier two israelis were stabbed to death in tel aviv. 15 israelis and 88 palestinians killed since violence broke out last month still ahead - for the first time in decades, more mexican migrants are leaving the united states than entering. and the factors behind the numbers and what it could mean for the u.s.

i.s.i.l. uses techniques to expand its reach. its reach.

the federal government is taking steps to make it difficult for american corporations to avoid taxes. the treasury department issued rules against corporate inversions, the process by which a u.s. company incorporates in a foreign company and avoids taxes here. it will reduce the tax benefit

if a company operates outside the u.s. a new report suggests there are more mexicans leaving the u.s. than coming in. the pew research centers says that from 2009 to 2014 more than a million mexicans left the united states. during that period 865,000 entered the u.s. the net difference 140,000 more people moving to mexico. a professor who has done research on migration joins us. this looks at a period from 2009 to 2014. doesn't seem a surprise that there would have been a decline during the years the u.s. economic struggled. that's true. the downturn in the number of mexicans that comes to the united states is not a shock. we saw it since 2008.

even before. what is interesting is the number going into the negative. that is surprising. it's really kind of new. we have not seen this in decades. >> because it looks at a 5-year period, it doesn't seem clear that the shift is ongoing. from an economic standpoint. why would it. the mexican economy is not growing faster than the u.s. economy. the peso weakened and property rate in mexico has slightly risen. >> there's factor in mexico. mexico, like the united states and the industrialized world is an increasingly growing and grey population. that means they are holder. >> the fertility rate dropped dramatically. there was a time when the mexican woman had a little over

two. there are fewer young people competing for jobs and the older eem are competing and the governments are not that bad. it's relatively well. for many mexicans, why risk the possibility of dying crossing the period. and being stigmatised, and people calling you murder and racist. it's a marsh decision to make. >> another important factor. i am sure when people here about the study, didn't they see the crisis, a wave of immigrants. that influx pass n from mexico as much as central african countries. >> that's right. el salvador, guatemala, honduras - ravaged by poverty.

still war and the drug war, they have been racked by crime and violence, many are trying to flee it. they were refugees from violence. mexico has not had that experience, even though we hear about the violence, it's pretty much focussed on the drug trade and we haven't had that pressure on the borders for years. if you think about it. it doesn't mean america basically solved an immigration problem. why? americans are older too. they are a greying population, fertility is low and there's a demand for labour that people from countries like mexico come to satisfy. what happens is as mexicans become less likely over the jobs. they'll turn to other countries. others were willing to take the jobs. what will happen is many people say what happened to the mexicans. >> the report raises the fact

that it could be that the chinese are the largest numbers coming to the united states. do you see mexican numbers rushing to levels of the past. >> americans change and see mexicans as contributing to the society, making the economy better and maintain the lifestyle that most of us appreciate. i think it could - in a sense we could entice them to come back. it will take a great deal of change, and if the american economy booms, it will attract more immigrant labour from mexico. >> good to have you with us tonight. >> thank you very much. >> i.s.i.l. released a video mentioning u.s. stay, there are no slats to the state. but dropping the game sparked

coverage. >> it's an example on how a propaganda regime was using the internet. >> the attacks in paris were seen on screens around the world. caught in this video published by daily mail. heard live during this broadcast. violence captured on video has become its own language. >> it's our time to spill blood. >> i.s.i.l. deployed it endlessly and expertly. professional looking video released. often with subtitles and news experts. the brand is the identity of the propagandist. propaganda is not new.

>> propaganda comes in two forms. one is raising the awareness, the consciousness, the patriotism, the limity of people that it's aimed at, and it's also working towards the enemy to try to take away their will to win. >> it's worth noting that u.s. military recruitment videos use the same playbook, offering a chance to be heroic and display the fire poufr of the united states. >> the techniques used are drawn from contemporary media. this is it a video put out capturing a jordanian pilot and later they execute him. i will not show you that, it's too horrible. in the lead-up to interview him they do graf axe setting up the story. later when they talk to him, there's an effect where they

interview and some out. it looks familiar, that's because you see it all the time. in video games. here is 2009's call of duty, one in a series of games, a popular video franchise. it's the same effect, that flashing in on the map. it's worth noting that later in the game they are called upon to shoot up an airport. execute civilians, a crowd of them. them. c you can get through the scene without doing this. you are given the opportunity, western media puts out this all the time. c.j. wilcox is doing this stuff, but it's no wonder the propaganda is mirroring what we put out. >> it's fetishising using camera techniques, storey development, and image eye candy that we are used to seeing in the main stream entertainment industry. at the same time it's haunting to urs, no one more than the united states has, despite the objections of parents and school teachers and psychologists and everyone else in no one but the united states fetishized violence. >> i.s.i.l. is following an effective rule of publicity. keep supplying the media.

with fresh images. al qaeda put out sporadic footage, but every week i.s.i.l. offers something new for journalists to pick up. in a world steeped in our media, the difficulty for the audience is being able to tell the difference between fiction and reality. . >> former subway spokesman jarrod folkel has been sentenced to 15 years in prison. he pled guilty to child pornography charms, and obtained and viewed material for 14 minors. he is known for losing 200 pounds on a diet of subway from their chain scientists engineer the first genetically engineered animal. consumers may not know it at the mark. why concerns about foodlabeling

has come up and the use of antibiotic in livestock - it has now created a super-bug that can't be killed with current drugs.

scientists warn of a potential epidemic from a super bug, a gene making it resistant

to antibodies, and spreads between species and transferred between animals, people and food. researchers found the gene in ecoli and pneumonia, china is the only country where a bacteria containing the gin has been found sexually transmitted diseases are on the rise in the u.s. clameddia is by far the most common. goneria increased between 2013 and 2014. cases of sif illous spiked by 15%. the f.d.a. approved a fish. it's a salmon genetically engineered to grow faster. we have more from seattle. >> reporter: these fish are as fresh and wild as you'll find in a shop.

in the next few years there could be competition from farm raised salmon. >> i think in the pacific north-west where they have ground zero salmon, we'd have a hard time selling it to the public. >> reporter: aqua bounty technologies worked on the concept for 20 years, using land based fish farms. the company claims it's man maid sterile genetically modified salmon, going to maturity paster than formal. >> there may be a place for that. you have to address people that have a price point. this from the center for veterinary medicine. it analysed and evaluated data and information. regarding aqua advantage salmon and determined they met the

regulatory requirements for approval. including food from the fish is safe to eat. genetically modified products have been part of the food chain for years, in the form of grain and vegetables and feed for livestock. the salmon is the first genetically modified product approved by the f.d.a. but there is no regulation for is to be labelled such. aqua bounty is certain to face pressure against environmental groups opposed. winning the hearts and minds of americans could be a problem. >> i think it's another way to cheat mother nature for a higher profit, big money. >> i'm an organic guy. i don't like g.m.o.s. >> probably if i was offered some, i would try it. >> aqua boundary expects it will

be several years before the fish with the tweaked d.n.a. makes it to the market. >> i'm antonio mora, thank you for joining us. luis suarez is next with "inside story". have a great night. night. over the past several weeks, college campuses around the country have bloomed into demonstrations, marches, and demands that key administrators resign. it's not just think university of missouri and yale, the rumbling are spreading along with debates about the limits of free speech. reading, writing, and race, it's the inside story. ♪
