news. it dates back to a generation that wants to hold the information this their hands. keep it here, don't change the channel. the news continues with jonathan betz. >> this is al jazeera america, i'm jonathan betz in new york with the stop stories. more shootings and knife attacks with no end in sight. increased security doing little to stem the violence between israelis and palestinians. >> the country reeling from sexual violence, two children attacked, including a toddler in separate incidents. >> a notorious fugitive el chapo tracked down. officials say he got away again. he's tending more troops.

we look at american troops in africa tear gas, stun grenades and rubber bullets. israeli forces trying to subdue protesters, the death toll is rising in the israeli palestinian conflict. four were shot dead, a fifth wounded in what israeli officials say was thwarted knife attacks. 42 palestinians and seven israelis have been killed. the chairman of the joint chiefing of staff arrives for a look at the escalating violence. >> a flaming tire rolling through the army lines. the occupied west bank city of hebron was an lock down after two stabbing attempts by palestinians on israelis. the palestinian witness to the

aftermath recorded this video of the first incident. israeli soldiers stand over a body. a white-clad settler looks on. the military says a palestinian man tried to stab the settler, but the settler reacted and stopped him. an eyewitness, a palestinian schoolgirl told al jazeera by phone she saw no knife and moments earlier the palestinians were taunted. in another part of the city, a female border police agent shot a palestinian women dead after being attacked. >> during the morning shift, a palestinian woman approached me and asked about a certain street. i told her i don't know of the street. she took out a knife and tried to stab me in the neck area. i pushed her. i prepared my weapon and shot her while she was neutralized.

clashes erupted. a commercial hub. ambulance personnel said three were wounded by rubber bullets. in addition t salvos of tear gas, troops have been authorised to use live ammunition. around the same time protesters were confronting israeli security forces on the outskirts of the west bank city of ramada. a day of finals. one of 19 for palestinians kid. >> by nict fall, australian military and police reported five stabbings. they continue to throw up concrete checkpoints, in a bid to stem violence. >> donald, the co-director at the middle east center for people in north-eastern university, they believe the

conflict has the potential to escalate further. >> in terms of where this is going, it will be hard. even with it israeli security measures put in place to stop the attacks. i think the danger is that there'll be revenge attacks, retaliation by settlers. we are seeing that happening, and that increases the violence. the real tipping point could come if organized palestinian groups, if hamas, palestinian jihad and fatah are involved, and direct the attacks. at the moment they've been spontaneous. if palestinian armed groups are sponsoring or getting involved. we'll see a greater level of violence. >> waxman says the u.s. can't do much to stop the violence, except getting both sides to tone down the rhetoric. >> two children's are the latest victims of rape. a 5-year-old and 2-year-old were

attacked in the capital. >> a warning here - some might find the report difficult to watch. >> a police forensics team works on site. another grim crime scene, but with a difference. a young child was said to have been raped here. at another location, another child brutally abused. one of the children had been gang raped. >> delly's chief minister arrived at the hospital, where a victim was being treated. >> together we need to create an environment in new dehli in which our mothers, daughters can feel safe. which is not happening now. that means there are shortcomings in security. the new delhi government is doing everything in its power to prevent such situations. i feel they need to play a bigger role. we are trying to help them. the prime minister should personally intervene in the matter, too. >> women's groups form to make

the capital safer, expressing horror and diskust. what is happening in delhi. i cannot understand. we met the 2.5-year-old girl in hospital. she had scratch and bite marks. what kind of delhi is this, what kind of animals are these. and on the out skirts, a family mourned the death of her teenage daughter. she committed suicide after being talked by a group of men. >> we first went to the police station at night to lodge a complaint. the police did not take action. they went to the police station, but the police did not do anything. >> police say they are now investigating. the family say they kept reporting what was happening to police, but nothing was done. >> preliminary investigations indicate that the girl had

complained of harassment. based on which a case was registered under case 394 of the indian penal code. >> reporter: new ain't rape laws were introduced after the rape of a medical student on a new delhi bus. since then, the numbers of cases has gone up. especially in the capital. >> the brutal sexual attacks against two young children shocked millions of people that live in the city. many are asking what other horrors need to happen before reapplication is taken to combat sexual violence against women and young girls. an issue strike killed a top al qaeda commander in syria. a saudi man died on thursday in northern syria. it's not clear if the air strike was part of a u.s. effort

against i.s.i.l., or one carried out by russian agent. russia released this video claiming to target i.s.i.l. it's home to many anti-bashar al-assad rebel groups. they offered to discuss military goals with other nations, including the united states. >> political issues are the ones that should be discussed by russia, the united states and all others with a stake at seeing piece. and a strong government. it does not matter who will be at the helm. we don't want i.s.i.s. to run syria. it should be a civilize the government. >> russia began its air strikes more than two wicts ago. it had been bombing i.s.i.l. for more than a year now. hungary's latest move has been diverting the refugees through europe. most migrants must find a way through slovenia, calling in the

army to handle the flood of people. captured on camera, and caught up on political posturing. these refugees were registering. which finds the focus of the flow of thousands reaching northern europe. >> the people look healthy. as you see, slovenia has been prepared as much as it should be. people are coming in. they were taken further to accommodation centers. some experts, the population of 2 million will not cope with the influx of people. they react quickly. it is important that we reinforce the police, that we would provide logistical support. >> reporter: for now, they are bussed to the border with austria, that bit nearer. the country that many want to reach. on friday night, hungary closed

its border with croatia, hungary's government called it a reaction to the failure of e.u. leaders to reach a response at the summit in brussels. a month ago the border with serbia has been shut. some migrants that entered the country appeared in court before being given expulsion orders. >> they are criminalizing people fleeing from war, and persecution. that is something that is not allowed under international law. you cannot penalize asylum seekers. in the last month, 190,000 people passed through coer asia, and for now they are not stopping. saturday, the first train carrying nearly 2,000 arrived in the croatian town, bordering slovenia. no one knows how long the route to a new life will stay open a hard-fought election campaign is coming to a climb amp in canada.

in two days the country will choose a new prime minister. incumbent conservative stephen harper is seeking a fourth term, challenged by a small field of strong candidates. john terrett has more from toronto. canadians go to the polls on monday in one of the closest parliamentary elections >> it's the only campaign in canadian history where each of the major parties have been in first or third in the opinion polls, which is unprecedented. >> the main parties are conservative, led by bookish stephen harper, who has been prime minister almost 10 years, running on a low tax, family values and tough security ticket. >> on a good day you get to go home feeling you have lived up to the job. >> it's time for a change in the country. a real change. the liberal party headed by justin trudeau. whose good looks and charisma

are attracting attention. the style has been borrowed from president obama in 2008. real change now. >> this is canada. >> justin is the son of canada's famous prime minister, pierre elliott trudeau. often in the tabloids for a playboy lifestyle. he was considered, but some see him as the second lacking authority of the father. >> movie reel: for many years i fight for the right of reason... >> there's a lot of people that would rather have a nonconservative administration that is an important objective. he is benefitting a huge amount from that. even where people don't have their minds made up about them. and there's an ndp. this is a high-profile candidate. this is olivia, the party hasn't held office. the party's best known for helping to create the universal health care system.

>> my plan is built to last. i have the experience to get the job done. the campaign centered on tory leader harper, the second-longest serving prime minister. he's alienated many canadians. 60% wanting him gone, for overstepping his powers. on security and stirring up ill will, particularly among muslims. they endorse the conservatives. but in a bizarre twist. it said it's time for harper to go. as things stand. the polls are on course for a fourth minority government. j should americans care about politics north of corner. conservative harper is in favour of the pipeline and for the trade deal, putting them at odds with a democratic future in the white house. justin trudeau said he would

pull the canadian planes fron the u.s. coalition bombing i.s.i.l. targets in the middle east. well mexico's top drug lord made another great escape three months after tunnelling his way out of a maximum security prison. joaquin guzman, known as el chapo is thought to have injured his face and leg, narrowly avoiding recapture. >> thailand's government is . >> the world's most wanted drug lord has got away again. in the mountains of northern mexico, his birth plate and regular hide out. after heavy fire, soldiers move in. it was too late. once again, the leader of the powerful sinaloa cartel slipped through the net. not unscathed, authorities say this had wounded in the head and leg.

the missed opportunity came days for a great escape from a high security prison in july. the sound of tunnelling is clearly heard, as can the voices of the men. as can the men that helped. incredibly the guards did not react to a barrage of noise, until long after joaquin guzman banished. it's the second time he escaped from a mexican gaol. >> the mexican government has been paralyzed. they've become a symbol of corruption and at least recapturing the drug lord would compensate for the loss of credibility. >> despite a long list of the crimes, including murder and mundy laundering, joaquin guzman turned into an antihero. to the point that el chapo masks

turned into an accessory for halloween here. the man, himself, is wounded, hunted, but still at large. still ahead on al jazeera america american troops will deploy help in the fight against boko haram. we look at the u.s. military's role in africa. and we talk to a doctor about the findings in relation to ebola research. it can survive in men lodger than believed, even after they seem cured. >> it's been overpromised. the worse thing we can go is overpromise a service, and not deliver. >> later the so-called female viainga goes on sale. there's lingering questions about whether it's good for women. the only way to get better is to challenge yourself,

and that's what we're doing at xfinity. we are challenging ourselves to improve every aspect of your experience. and this includes our commitment to being on time. every time.

three of many armed group, purely in the quiet build-up of africa. the u.s. military's africa command. >> the biggest concern for africa right now it the spread of jihadist groups, and the country's obviously of most concern are in the ark that goes from nigeria up through libya, tunisia, egypt and then down into the horn of africa, particularly somalia and djibouti. >> launched in 2008, u.s. africa command grows the operational footprint. with cameroon now emerging as the latest deployment area for u.s. troops to assist in the fight against boko haram. according to author nick turs, the u.s. carried out 674 military activities across africa last year, a portfolio that encompasses special

operations, humanitarian support, training and coordinating with african nations and intelligence reconnaissance support. the u.s. escalated military presence, effort to tackle the causes of security threats have been less robust. >> case in point - somalia, where the u.s. helped african partners reclaim vast swathes of territories, but is yet to reopen an embassy in mogadishu. a lack of follow up claimed on the fall out on the benghazi embassy, that killed christopher stevens and others. >> benghazi, the overarching concern, that u.s. can't lose anyone else, there's not sufficient political follow through to deal with a host of

governance, economic problems in a number of african countries. >> problems, which if left to fester may leave the u.s. presence in africa to spread further. patricia sabga in al jazeera. enjoying us to talk about this is a former ambassador. from the republic of congo, and director of the african center at the council, both in washington d.c. let me start with you - you spend a lot of time in africa, is the united states increasingly upset about the continent. >> we are becoming concerned about the country, because of the threat of the islamic state in groups like boko haram, and al-shabab. certainly along the region, that includes nigeria, cameroon, chad, niger. these are very, very key issues

for us, and particularly not only because of the internal threat within the countries, and the new connection, of course, that particularly groups like boko haram and the yate -- islamic state. >> when you look at the threats, is the u.s. challenged trying to cover all the fires that have been burning? >> well, i think the u.s. is increasingly recognising africa's strategic importance, not only because of threats you mentioned which are real, but certainly which bear attention because they do touch upon u.s. centers and the partners. it has a dynamic force in the world, a growing economy. seven of the 10 fastest growing economies this decade will be african countries. the strategic sponsor and recognition is a watershed

moment in relations with the african relations. should the focus be on battling these groups, or on helping the countries build their own militaries. i think it's not an either or. african security is key to development. they go hand in hand. the countries have to own both, the development and security, it's in the u.s. interests. the partners build up capacity to help them stand up. in cases where they are challenged, where they might need an extra lift. that's what friends are for. that's where the united states could help. it should be african led and owned. >> give us a sense of how the presence of the united states in africa will change over the last

10 years. african did not exist a decade ago. >> there two things that are important to be precise. first they had the continent. not just because avery come came on the scenethe scene. we have done training, professionalition of the military and had military cooperation. that is one basket. let's not forget that will continue, no matter what. what we see now is a shift that focuses on the threat. not all african countries are facing this threat. when we tend to talk about africa, we talk it it with a

single paintbrush. the doctor is absolutely right. it is a dynamic country. you have a number of growing democracies, the 10 fastest growing economies in the world. you have a population that is vibe rant of the of the 30 million apps, a lot is the produced. you have a vibrant economy and continent. you have threats where african nations like cameroon, niger, all asked us to step up and come in. i was in the u.n., the president requested that he needs to address boko haram. cameroon obviously has done the same thing with this request of 300 personnel that are going out there soon. >> when you look at the request and threat of b, i want to play a quick report. and you get the reaction, it's from the reporter on the ground

in nigeria. who explains why the u.s. troops will be a welcome site to african forces. >> the presence of the united nations forces will government the site of boko haram. they are deploying 300 personal. experts believe that the key components of the war, missing from the early stages of the campaign was intelligence. they hope with the presence of the united states forces on the ground. regional forces will enjoy or share information or intelligence regarding the crisis. >> this is not the first time america is sending troops to fight, or to help in the fight. in the wake of the kidnap of the chibok girls. and countries outside of europe and other parts of the world. they have sent in support in terms of equipment to help

locating where the girl's are, and, of course, to deal with the issue of intelligence regarding the fight against boko haram. people are waiting to see how this will come into play as the multinational joint task force await the mandate to start provisions in the region. >> bring back the girls - the girls are not home. when you look at what is happening there in the fight against boko haram. is the u.s. and its partners there winning the fight? >> well, let's be honest and frank with each other. the fight will not be won in days, weeks or months. this will be a long process, one that ebbs and flows. >> right, but is progress made? >> i think progress is made. and the deployment of the 300 personal order by president obama will help to increase that. certainly in relation to that

report. intelligence gathering and sharing is vital to the operation. they'll add a new dimension. cameroon has one of the best something military units. a rapid reaction force, which enjoyed u.s. training and equipment. they were trained to deal with disorders along the coast. they were an amphibious unit. that was part of the mission, helping to retrain them for the desert warfare. they are a capable unit. raising the level of professionalism above what it is. then, of course, transforming the military. nigeria's military, it is valiantly working against boko haram in many instances is a small military commencement to the populous country, the largest economy. it will take time to build up the military and train and

indoctrine it for the new counterinsurgency. all this will take time. >> it will take time. the argument is also the fact that cameroon has been asking for help. nigeria has been asking for help. these are indications that the kuehnion and countries cannot do the job of fighting for boko haram. do you agree with that. >> there are two things that are important. the military has been, up to this point a conventional military. they says asymmetrical warfare. the type much reaction, training, units needed to face asymmetric warfare are different to conventional warfare. prior to this. nigeria was the largest company contributing to u.n. troops. they are professional military, they've had hiccups, they need to address the human rights issues. that said, having additional

assistance from the u.s. is important. i disagree a little bit with the clip that you shows us. prior to the cameroonian - the troops going into cameroon, there were advisors in nigeria, when the chibok girls were there. i think there was about 24 or more. we had some, of course. we have contributed to intelligence, on logistics. and in terms of training or stepping up training in certain areas. we have done that. it may not be known to the public at large. we have been doing that. the difference with the cameroon question is cameroon asked for specific things and troops, coming from african to do that. we have to continue to be precise. the difference between combat troops that will participate in advising, providing intelligence

and doing logistics and assisting command and control. >> they'll be in surveillance. there's a player they we have not talked about. it has a strong presence in africa, it's been investle and is expanding the military strategy. the president pledged 100 million in said to the african military stand. china provides a helicopter squad to insist on it. it builds a chinese military base there. >> is china's involvement in africa good for africa? >> well, i think it's up to africans to decide. certainly whenever the more suitors, i think africa could benefit. we made the mistake, we do one

of two things, one is to reduce this to a zero-come competition. africa shouldn't be the focus of a war between competing powers. the other thing is to review all interventions and outside assistance, whether from the west or china, each one has to be examined in its own right. with that said, african countries need a bit of help. they need some help. so help is welcome. as long as it's structed. it doesn't change the balance in any untoward way, and there aren't secret side deals. >> are you aware of the criticism and concern that if china gets in, that it will help bad leaders do bad things.

well i think you have to benefit a few things. especially if they assist in training and other things. that's not going to be a bad thing. you have 54 countries. there's a lot of challenges to go around, and the more partners that africa has is not a bad thing. i will agree that it's up to the africans to decide. countries are not pieces on a chess board. they could have a say in what could happen. asking china to come this is not a zero sum game. yes, they need to stand up and talk about political issues. and certainly see china play a responsible role in not providing that kind of assistance to government not treating the people well. we have to separate that. they can use training and

resources in other countries besides ours. i think that it's important to keep in mind that there's a national security component. book -- boko haram, not only did is it pledge allegiance, it's called the i.s. west african province. meaning that it was worrisome to us in the united states. now with this official design that they have for boko haram, or being part of i.s.i.s., what kind of threats that brings to the region, but potentially to the homeland. don't forget the n.a.s.a. security component. >> without question. this is getting a lot of attention, moving parts and players. thank you both for joining us tonight. >> thank you for having me.

>> a new product hits the market that could change the lives of thousands of women. >> we haven't seen anything that will be as powerful or as important since the 1960s, when the pill was introduced. >> so-called female viagra goes on sale today. that story next. >> also ahead. anti-ox dents known as fighters. why is research saying patients may want to avoid them.

>> puerto rico's debt crisis. >> they're gonna demonstrate right outside where the governor lives. >> are hedge funds offering a fix? >> those investments will spark the economic recovery. >> or just fixing the odds? >> they're trying to force us into one course of action. >> "faultlines". >> what do we want? >> al jazeera america's hard-hitting... >> today the will be arrested. >> ground-breaking... >> they're firing canisters of gas at us.

>> emmy award-winning, investigative series. after months of positive news in the fight against ebola, a setback in a country affected. two new cases have been detected in guinea, a study of survivors found a group of women appear to be immune. a week ago. sierra leone reported no new infections, a country is expected to be ebola free after 43 days. researchers learnt that the virus could live in the semen of male survivors for nine months after infection, a lot longer than previously thought. >> a scottish nurse treated for ebola in the u.k. a year ago, appearing to make a full recovery. she has relapsed and is ill

undergoing treatment in a london hospital. joining us from miami is a doctor, a professor of infectious disease from florida international university. thank you for being with us. >> pleasure. >> there's a lot we don't know about ebola. how surprising were the findings to you? >> some more surprising than others. some was information we did already know. where would you like to start? >> you tell me. i'm struck by the nurse in the u.k., who is now dealing with ebola again. that seemed to be a major surprise to a lot of doctors, yes. >> that one is very surprising. it is apparently a resurgence, and not your typical post-ebola syndrome that we see in a lot of patients. it's alarming at various levels. number one is, you know, the way in which he manifested the disease, this time is different to the way a patient normally does. it's harder to recognise what was going on.

>> how did it mann fest differently. what happened? >> she has a meningitis-type of syndrome and didn't have the usual normal vomits and nausea that we usually see. >> is now the concern that people we thought was cured may not be cured and we could see a resurgence of the virus. >> that is the big question from what has happened to nurse cafferty, and based on what we now know about her, there's a number of individuals in africa that have had similar types of presentation where the studies were not done. so it's likely that this has been happening and we just were not aware of it until now. >> so we are hearing about a man that transmitted ebola to a woman via unprotected sex, and it happened 155 days after he

was declared ebola free. how does this change everything that happened with this virus? >> we have known for a while that it can be in the semen for prolonged periods of time. there have been prior reports that would endeem logically suggest that it could be transmitted by sex. what is different now is they have done a careful genetic study of the ebola virus in in man, and compared it to the exact ebola virus that infected and killed the woman he had unprotected sex with, and it was unique and identical. therefore, we now - it's no longer a well, we think it might happen, now we know it happens. >> now we know and it's confirmed. does this mean that we should be afraid of contracting ebola from people thought to be declared ebola fry? >> well, for the most part, someone that is a survivor, and survivors have a lot of things to deal with, including post

ebola symptoms and so forth that can be harsh on their lives. generally speaking, the virus is not anywhere that is easily transmittable to other people. most are clear entirely. there are some you neat sites in the body that are immunologically privileged sites and they are places where the ebola can stay, like your gown adds, line -- gonads, joints, the brain, spinal court and if it's in the gonad, is it can go into the semen, and the second study demonstrated virus in some people, 25% of the people that they had studied 9 or 7 months later. they had evidence of ebola virus in the semen. >> help me to understand. do we have a clear idea of staying in the body.

and how it may be transmitting the violence of other people. what we know is now, for sure, it can last in the semen for a minimum nine months. >> minimum, but it could be longer. >> yes, it might be. the study needs to go on. it's just that this study was released after they had - the longest person they saw was an individual that had 10 months post ebola. that was clear. that doesn't mean they don't have it for longer. there were individuals that were only nine months and had evidence of ebola in the season. >> any horrible disease that is presenting a lot of troubling questions. >> thank you for your time tonight. >> my pleasure. >> thanks jonathan. >> the female viagra pill went on sale. it comes with controversy and risk.

courtney kealy is here with more. >> it's been called the female or pink viagra. it's chemical name is flebanseran and it's on sale. some women consume, national consumer league say it's about time. >> this is a milestone >> this is a milestone. this is a breakthrough. we haven't seen anything as powerful or important since the 1960s when the pill was introduced. >> the drug was originally developed as an antidepressant before being repurposed. the pharmaceutical makers said it enhances a woman's sex drive, when it hampers neurotransmitters in the brain. it is specifically for the 10% of premenopausal women. they suffer hyperactive sexual skies disorder or hs d.c., which is described as an absence of thought or interest in sex.

>> women take a pill once a day at bedtime. it takes four weeks before a change and eight weeks to feel the full affects and comes with side affects. low blood pressures, nausea and fainting when combined with alcohol. >> i think it's been overpromised. the worse thing we can do is overpromise a service and not deliver. >> this doctor runs a women's health center in beverly hills and has patients with sexual function disorders. he claims it's not effective. >> when you look at desire. there was zero improvement in placebo. or the medication. however, when they take a look at, say, the enhancement of the pleasure of the experience, i think that's a nice way to put it, there was an improvement. but there was an improvement with the placebo as well. more with the pill. some with the placebo. as far as desire, zero. >> the federal drug administration rejected the pill

twice before in in 2010 and 2013 because it didn't show a significant change in women's libido over placebos. on average, women on the drug reported having one more sexually satisfying event per month. than women taking a sugar pill. critics said the pill was a mediocre aphrodisiac. it has been promoted as a way for women to take control of their sexuality. >> some say the f.d.a. was pressured by a marketing campaign using the argument saying women deserved access to a drug, and a decision was based more on that that evocation. whether it works, the canadian drugs company acquired sprout for $1 billion. sprout is looking to file for approval in canada by the end of this year, and europe in 2016. a new study suggests patients with cancer should not

add antioxidants to their diet. vit men c. d and beta-caro teen is thought to protect healthy cells. it also turbo charged the process by which cancer cells grow and spread. cancer patients are urged to be careful with substances promoting disease fighting properties still ahead - cleaning up in california - cleaning up highways. inmates allowed to battle the wildfires.

a massive and messy search continues for victims of a mud slide north of los angeles. thousands of cars and trucks were buried along highway 58 in the antelope valley. it appears everyone made it out allied. the mudslide was triggered by two interests of rain in half an hour. something meterologists were calling a 1,000 year event. california needs more help fighting the historic wildfires. the state is enlisting prisoners. now they are thinking of going further and convicting those of

violence crimes. >> reporter: inmates have been helping to fight wildfires in 1946, the oldest such programme. >> for us the priority is the safety of public, our own employees and responding to national disasters. it's something these inmates do on a daily basis. >> reporter: prison officials are allowing inmates convicted of violent crimes into the programme. >>. >> maybe we can include them with a good good behaviour problem. >> at time when wildfires are burning more in californian acres than before. >> we had a regard year that eclipsed the record of wildfires that we had last year. if that's the trend for the future, we want to make sure we have enough inmates available to fight the fires.

>> arsonists. sex offenders, kidnappers and gang members and those serving life sentences will be included. some professional fire-fighters are worried. into my concern is the safety of fire fighters, with one person managing room-mates without additional help. >> reporter: some residents are concerned. >> that worries me. i have two young kids. i don't know what the crimes yn, what they are convicted of, what they are capable of doing. >> reporter: while nonviolent offenders have been allowed in the inmate firefighting programme. there has been criminal incidents over the past 10 years, most of which involved assaults among prisoners. some californian residents would welcome any help against raging fires. >> i suppose in a moment of crisis i wouldn't check credden shells, i would be happy they

were out protecting our homes. >> also ahead - they are little but are creating big trouble in florida. the effort to get rid of the pesky lion fish. for $1 billion. sprout is looking to file for

it. tourism is heating up in cuba thanks to thawing relations in the u.s. more than 3 million visited the island, a 50% jump from the year before. the boom follows the normalizing of relations, after more than 50 years. the country's main challenge is providing resources to meet the growing demand. >> cuba has been working very fast to provide quality services to clients from around the world. >> this is my first time to cuba, i'm coming again. >> the government predicts the tourism boom will create tens of thousands. >> see world is fighting a ban
