as the pope visits the u.s., we take a closer look at the pope and the mafia.

>> and more than 500 million books sold. best selling author jackie collins has died. >> good evening. i'm richelle carey. we begin tonight with the arrival of pope francis in havana, where it's a historic trip to cuba and the united states. the pope ended his first day with an evening on the town. after dinner he spent a few hours greeting 30 to 40 pre-selected guests. this wrapped up a long day filled with much pomp and

circumstance. we have reports from havana. >> hope francis touched down here in havana and met with raul castro of cuba discussing a variety of topics most likely the normalization of relations between the united states and cuba, something that pope francis helped to forge. he also met with castro is to discuss some of the religious issues here in cuba. they would close down churches and confiscated property. so there is a long road ahead in terms of relationship between these two parties, that's most likely one of the issues that pope francis will take on as he travels the island. there is a growing sense in havana that cuba may be changing its tune. [singing] >> as i island prepares for the

third papal visit, much can be attributed to this man, pope francis. >> for some months now we have been going through the process of normalizing two peoples who have gone through years of estrangement. >> one day before the widely anticipated sermon, this is where it's all supposed to happen. >> pope came here to deliver a mass to hundreds of people. but when pope francis comes here, he'll do so as the first latin american pope, but the pope who help to broker change

in relations between cuba and the united states in more than 50 years. even in cuba even non-believers seem optimistic of what this papal visit means. >> this is something that is very important for everyone. it brings calm to our country, and we hope it will bring new changes to our country. >> the vatican said that 60% actually attend church. still some cubans are hoping for a more active church in cuba, which currently does not allow catholic schools, radio, or religious expression. >> the question now is whether pope francis will use this trip just to spread the faith, or if he'll address more controversial topics such as human rights and

political prisoners, for which cuba has long been criticized. now pope francis comes from a jesuit background as does fidel castro and raul castro. there may be some sort of understanding to a bridge. this is the third papal visit, and the normalization relations between cuba and the united states, this past week we saw the nitty-gritty details of how that may take place. they'll be able to hire cuban employers in the embassy office they opened here. it is atribulated in large part to pope francis. >> a little later in the

newscast david reports on the changing relationship between the catholic church and the cuban political leadership, and the taboo issues that still strain those relations. of course, cubans have been anxiously awaiting the visit by pope francis. lucia newman is in havana with what they're saying. >> people tell me they're very excited. they don't want to just see the pope, they want to hear what he has to say. pope francis not only speaks their language, he speaks in the words of the common man. even non-roman catholic cubans tell me that they have high hopes that this pope will continue to facilitate a miracle. >> on behalf of the well-being of the people, of all america. >> people also tell me that they hope this poem will promote reconciliation and tolerance

within cuba. one party's faith dismisses people as mercenaries. >> we hope this brings love and peace among our own people. >> planeloads of pilgrims have also come from the united states. >> all this excitement underscoring a keen interest. >> in a was lucia newman. let's take a look at the rundown for the pope's schedule. pope francis will travel to washington, d.c. on tuesday to begin the u.s.-leg of his trip. on wednesday he'll visit the white house, hold a mass to canonize spanish foreign monks who built missions across california. and then he'll make history as the first pope ever to address a joint session of congress. on friday, in new york city he

will address the u.n. general assembly, lead a procession through central park and hold mass at madison square garden. then it's on to philadelphia for the technical purpose of the trip, which is the world meeting of families where he'll hold his final mass a week from tomorrow. do stay with al jazeera america through all of next week. we'll bring you complete coverage of the pope's visit to the united states. secretary of state john kerry worked the syrian crisis in london. along side british born secretary philipp hammond, he said that they cannot be part of syria's long-term future and calls for him to step down. he said that syrians are speaking with their feet when they flee their homeland. >> john kerry met his british counterpart philipp hammond in central london, and after the

meeting kerry said that they discussed ways to push for a political solution to the syrian conflict, and what he calls for this moment in what rush appears to be more committed more against isil, what kerry believes is a common aim between west and russia defeating isil, particularly through airstrikes. at the same time, he said he was concerned about the prospect of russia increasing it's military support for president assad with the russian fighter jets already in the country. and he might have made a small concession when he said that president assad did not have to go on day one or month one, but he still insisted that assad did not form part of syria's political future. that's always been a sticking point when it comes to getting serie-s syri' ria to the

talking table. >> we have made it clear we've been open. we have made it clear that we're not being doctrine about the specific day or time, we're open. but right now assad has refused to have a serious discussion, and russia has refused to bring him to the table to do that. that's why we are we are. >> the two men discussed the refugee crisis something that they have called the humanitarian catastrophe. he'll go on to berlin and speak with chancellor angela merkel, and whether other countries can take in more refugees themselves, perhaps backing this idea of a quota system, something that merkel is very keen on to take the pressure off herself. but kerry stressed the ultimate solution is not about dividing

up people in terms of numbers or giving them more assistance in europe, but solving the core problem which is the conflict, the violence in serie-a and the lack of hope for young people in the region. clearly he's very, very concerned about getting things speeding up politically in syria. >> coming up we'll look at russia's military build up including the role it's playing in syria. that's ahead in just a few minutes. european countries are shifting around tens of thousands of people this weekend. thousands of them finally boarded trains on the croatia croatian-serban border. it's not clear where thos those trains are going. some trains went through the austria border today. it's part of the 10,000 arrivals

that austria is expecting just in one day. many hope to end up in germany. many are escaping the syrian war or leaving dire conditions in refugee camps in lebanon, jordan and turkey. >> only $1.05 a day, but it was enough for the family to get by. now even that small amount has been cut off as of this month. it's easy for them to find work, but they watch the baby while the other works. >> we have no more fears for the future. we don't know how much worse our situation can get. >> the world food program said that it is seriously underfunded. they now have to make life-and-death decisions about who to feed and who to cut off. this family of 11 are in the

same possession. he works illegally on a nearby farm. >> i would take all risks to return to syria because i'm being humiliated and enslaved here. i work 13 hours a day for $14. is that enough for my family? >> the food and security levels are skyrocketing. almost 70% of refugees in jordan live under the poverty line. after losing their food assistance refugees say they've lost faith in the international community. those who work for humanitarian agencies say that they're also frustrated because they're no longer able to maintain their services, and they're worried that desperation will push some refugees either to go back to serie-a or risk the treacherous journey to europe. >> for many refugees that is the decision they must make in the coming weeks. >> many tell us that they've lost hope for the future in the

region. many are returning to war in syria. those people in the worst situation have told us that they will risk their lives to reach europe. >> syrian refugees have fled their country to escape war because they had no food. in jordan the authorities struggled to cope and relying on the u.n. and ngos where they could. but now those resources are drying up along with any hope. al jazeera. >> join us in the report o " "desperate journeys: a global crisis" on sunday at 9:00 p.m. eastern. live pictures from athens at 6:14 in the morning. polling station also open in less than an our when the left week syriza party promised an end to austerity.

but months later the situation has evaporated. barnebarnaby phillips reports from athens. >> alexis tsipras has still has charisma, but it's been a bruising year. he said don't let the old party back in. the old regime that created the debt crisis in the first place. he may have lost to europe saying his supporters, but at least he went down fighting. >> alexis tsipras came to power promising to end austerity in the eurozone. well, he failed to end austerity. so this election is all about whether greeks are prepared to give him a second chance. >> it's the same story now.

>> i met young people who supported the left wing syriza when it won in january. he said that he would vote for them again. >> i think they are all corrupt. i have some hopes. >> but he said that he will vote for another party. >> i think everything will be the name. >> disappointment. disillusionment. words that sum up the national mood according to this analyst. >> the spark of hope existed in the last election. eight months back. this is gone now because the spark was part of tsiplas's image. it is gone. when you have this type of negativity it is very difficult to predict the result. >> this man is poised to take

advantage. leader of the center right new democracy. some warm to his down to earth style, but his party is part of the discredited political establishment. many greeks want to get away from politics. at an athens cycling festival they're enjoying the last warm evening before what could be a long, hard winter. some how a knew government will have to revive that spark of hope. barnaby phillips, athens. >> one of th. >> jackie collins has died. she had 32 best-selling books translated into 40 languages and sold 500 million copies of her work. among the titles, you know them, hollywood wives, lucky and lady

boss. look her older sister, jackie was born in britain but became an u.s. citizen. she was 77. coming up on al jazeera america. ukraine announces a deeper look in the world conflict. sure, tv has evolved over the years. it's gotten squarer. brighter. bigger. it's gotten thinner. even curvier. but what's next? for all binge watchers. movie geeks. sports freaks. x1 from xfinity will change the way you experience tv.

>> welcome back. it is estate night in time to take a deeper look. tonight russia's military little up in serie-a. president vladimir putin has made it a priority despite sanctions in a drop in oil prices that has negatively impacted the any. russia increased it's budgets for 2015 more than 25% to $60 billion. that is close to 4% of its gross

domestic product. roxana saberi reports on how russia is increasingly flexing its military might around the world. j russia's decision to deploy fighter jets to syria is one of its latest moves. >> clearly the presence of aircraft with air-to-air capacity as well as surface to air missiles raises questions. >> with the potential of rival u.s. and russian air operations oversyria, the u.s. and russia agreed to look for ways to avoid accidently attacking each other. the two former cold war adversaries say they share a common enemy in syria: isil. but president bashar al-assad, seeing him as the driving force behind the country's devastating civil war. russia's president said that

moscow's military support for assad will continue. >> we have supported the syrian government. i'd like to say that. we have provided and will provide all the necessary military and technical support. and we call on other countries to join us. >> russia's build up in serie- syria comes months after naming nato as a top threat to russia. russian officials say that russia has been beefing up it's presence in eastern ukraine. while still in a stand-off with nato after annexing crimea last year. and moscow has helped military drills on its arctic islands reviving airfields and open new bases. the new doctrine calls for more cooperation with counties such as india and china. for the u.s. russia's military moves are seen as provocative and potentially destabilizing.

>> we have seen that russia is investing more in their defense in general, but new capabilities in particular. >> but this could stretch russia's budgets thin, the kremlin is making clear it won't cut corners on defense. roxana saberi, al jazeera. >> joining us now to take a deeper look, retired army major and al jazeera's national military contributor. we need both of you tonight. mike, what could vladimir putin's motivation be? >> it's keeping a toehold in the middle east.

something that the united states has tried to keep them out of since the second world war. now syria has been a long-time russian ally. that has not changed. they always bought military equipment from them. but this is a way for him to get legitimacy there and insert himself in this peace process, but it's likely masquerading to keep assad in power. >> anna, what do you see as his motivation? what value does the assad regime have for vladimir putin? >> well, i certainly agree with mike's earlier comments. this is about increasing russia's influence in the you middle east and keeping the united states out of the region and of course this is about bolstering assad and so forth. i would like to add this is deflecting from the ukraine crisis of putin's own making.

at the end of the month he is expected to make a speech focusing on terrorism, to fight isis and other forms of terror. but this gives putin international legitimacy. he's trying to say we may have our differences over ukraine but we have a greater enemy we need to fight here. isis and other terror groups are a threat to all of us. let's forget about what i did in ukraine and let's focus on these other issues. that's another thing that he's doing. >> when it comes to isis or isil, which ever you choose to call it, is he all talk? could he possibly have a valid point? could he possibly be interested in joining the coalition to fight isil, of course the united states happens to be part of. >> i think russia has a global

interest. however, the problem is russia's action also show that they're not really interested in fighting. that with zero-sum game that putin likes to play with the west is more important to him than fighting global terror. >> you have to look at the kind of equipment he has brought to the battlefield. modern tanks, t-90 tanks, fighter jets. that's keeping the applies from creating a no-fly zone to create a safe passage for refugees that assad has been bombing. the kind of weapon systems that he brought to the battlefield don't say that he's going to fight a non-conventional force. there are fundamentally conventional arms to protect assad. >> is this going to create a

destabilizing situation? >> no question. i think it sends a deep ever message, unfortunately now we even lack a strategic deterrence. would he have done this had we kept 20,000 troops in iraq following the war there? it goes back to that in so many ways. what would have been the deter rants have been? shifting back to ukraine nato had a tremendous force there. they pulled out. he's pushing the theft when it comes to the united states. >> to that point, am i correct that the international community does not have a plan about what to do about serie-a? >> absolutely.

i would agree with this. putin is taking advantage of our reluctance to get involved in the syrian conflict and our own reinforcement of red lines. we say one thing and do another, and he's taking advantage of that. >> is anything going to change when there are talks to the u.n.? >> i think it's going to keep thup the bloodshed and it won't help at all. >> what do the people think about the moves that. >> some liberal voices do get through. what is interesting, how many

russian analysts are concerned that russia's build up in syria could turn into another afghanistan, a war that ultimately helped to bring down the soviet union. some analysts who support the kremlin policy has also raised concerns that they don't want russian citizens dying for assad. you know, whether or not that concern is real or not, it's perhaps the secondary issue. the primary is that russian citizens are concerned, and they don't want to get involved in this. >> she has a great point. russia has learned from afghanistan. they brought conventional weapons again to the battlefield but they're not going to engage isis, which fights non-conventionally. they had seen how poorly the united states did in afghanistan. they learned their own lessons back in the 80's. i don't think they're going to

engage isil. i think this is more or less talk. the conventional weapons are about protecting, and reinforcing losses from the assad government. >> is there an economic incentive for what russia is doing as well? >> no question. if the assad government survives as iran has the money release, russia becomes an arms dealer to syria, iran, and other countries there. he's taking the long game here from his perspective. you have armed president and administrations in the fourth quarter. they're trying to wrap up the game, hand out high fives and get out of dodge. russia is playing the long game by looking over the horizon saying we're going to be a power, an influencer in syria, and then selling arms to iran and any other country. it's a good deal for them. >> any way to anticipate what vladimir putin's next move might

be? >> putin is not very clear at sharing his intentions. but we can see a continued opposition to the west on a number of levels. >> i appreciate the conversation from both of you. we'll continue to keep an eye on the issue. anna, really proud that i think i nailed your name. >> you did, thank you. >> and focusing on russia's policy towards middle east. thank you both for joining us tonight. >> entrepreneur activist and leader, coming up, the former president malawi joins us and talks about the challenges women face and leadership roles.

>> pope francis is in cuba. he was greeted at havana's airport by president raul castro, who thanked the pope for helping with the united states. thousands are gathered along the route where pope francis' motorcade traveled this afternoon. pope francis is the third pontiff to visit cuba in the past 17 years. three visits in less than 20 years, there is a record. it might have helped to soften the relationship with the cuban communist party. we have reports from cuba. >> when pope francis delivered mass on sunday he'll do it on the image of another argentine. the massive mural that hangs in the cuban capital. it was che along with castro who turned against the church

driving out priests and declaring cuba an atheist state. this 75-year-old is old enough to remember. >> in the first years of the revolution there was a lot of antagonism between religion and the politics of the state. >> but that relationship has changed. shifting as joan paul made an historic visit to the island in 1998. today a different picture of cuba and religious leaders have emerged even if the issues those leaders raised are still considered a bit taboo. >> the catholic church is considered a major political player in cuba. the archbishop is one of the few men who seems to have the ear of raul castro himself. and this church behind me is where a group of dissidents used to meet every sunday before marching in protest of the castro government.

>> in years past they would orchestrate the release of political prisoners in cuba. but now dissidents ladies in white criticize the catholic church for not advocating enough on their behalf. just a week before sunday's papal mass, cuba detained some 50 dissidents including these members. but religious leaders, a cuban priest, say that the papal visit will not change the plight of prisoners. >> the theme of poverty, and prisoners. >> it's really this moment back in april for which pope francis may be most remembered even though he didn't attend. a surprise deal with helped normalize a half century of frozen relations between cuba and the united states was in part brokered by the vatican and it's work behind the scenes.

>> the vatican's involvement in this policy change was crucial. the support of the vatican and pope francis was something that was crucial to both sides. the respect for this pope because he's latin american, and his importance in cuba and throughout the hemisphere i think is part of the reason it's so well respected. >> on sunday for the third time in less than two decades this famous plaza in havana will again fill with those waiting to see the pontiff. the question, though is whether the four-day visit by pope francis will lead to even more long-lasting changes on the island. al jazeera. >> this week the united nations' general assembly meets in new york, and one woman will be there holding meetings to talk wittalk about women's empowerment. joys banda has overcome her share of obstacles as the first female leader in malawi.

let's talk about that huge leadership role that you had. what were the challenges that you faced in that role, particularly because you were a woman? >> i was fortunate that prior to becoming head of state i had served as minister of women and children, and i had served as foreign minister. and i had served as vice president. to an extent by the time i became president people had seen me in leadership position, and i've always said that i was very fortunate that i brought a lot of support from both men and women. i have also always thought that sometimes it was more support from men than my fellow women. what i remember most, there was a statement issued by an

organization, and i remember challenging this man to say that these are things in the past with the male president happened, and they were wrong. but here you are accusing me that it's wrong for me to provide free food to the most vulnerable group in our country. you say i'm giving handouts and i must stop. why are you discriminating like this and he looked straight at me and said because i'm a woman. >> he just put it out there. >> yes, he just put it out like that. it's the first time that it was put out flat like that. our emotion, our temperament and approach to leadership as women is different from men. in that situation you find that you can get resistence because people have to understand what you're trying to do.

>> when you say that a woman's leadership style is different, do you think sometimes there are people who try to make women feel like that leadership style is bad because different does not have to be bad. >> yes, yes. >> different is often good. >> yes, when you want to change the status quo. when you want to do things differently, sometimes women meet resistence. the tragedy is that times men want to fight you, they'll use other women to fight you. so you have to be very attentive. because men against women sometimes is through women. there, there is so much stigma right now throughout the world that women's leadership is under attack. you're expected to perform 100

times better than the man. >> do you think that sometimes that can discourage women from wanting to get into politics and wanting to get into positions of leadership when they see how difficult it can be for other women? >> i don't want to use my example, but i just want to look at australia. look at what they went through. if you go to thailand, philippines, myanmar, zimbabwe, argentina, brazil, chile, u.s. >> here in the u.s. as well. >> yes, u.s. so i am worried that women's leadership is under attack. because leadership is being redefined now. gone are the days when you come into leadership, and you are oppressing people. people are not accepting that any more. women have this style that

embraces everyone. dialogue and avoiding conflict, risk-taking. carrying about large projects and small projects, issues that effect women and children. there are people wh--leadership is about falling in love with the people. and the people falling in love with you. so people are realizing that women are good leaders. that's the greatest challenge because that's what people are fighting. because leadership has been redefined. that is why. people want a leader they can relate to, and a leader who listens to them. a leader who is a servant-leader. when people resist that, leadership is emerging from the marketplace. >> what do you think the future

is for a little girl born today? what is the future for her today? is it a good future? are you optimistic about it? >> i'm optimistic about it, it would depend on how we behave. those who are in leadership. we cannot afford to get discourage: we must accept that there is a price that we must pay for being first. but along the way these young girls will need role models. so what we need to do as women who do this is to stay the course and refuse to be intimidated. we can do anything, and you know people can rig elections but they can't rig the minds of the people. whether you stay in the house or outside it's a moral obligation for us to realize that the young girls you're talking about are going to need people to lock up to. the sadness is that they're looking at women across the world and how they've been

treated, and the names that they've been called, and the smear campaigns. so women, professional women sometimes hesitate to say, well, i want to compromise my profession to get into that leadership? >> all right, it's an honor to talk with you, president banda. thank you so much. former president of malawi. thank you. >> thank you. >> hillary clinton could soon have more competition from her own party. up next what everyone is asking, will vice president joe biden run for president?

>> there are all right 20 people running to be the next u.s. president, but there could be more. you're wondering if vice president joe biden will throw his hat in the ring. patty culhane takes a look. >> we'll soon know if joe biden's next time will be the third time a charm in his quest

to be president of the united states. he lost his son bo to brain cancer in may. it did not look like he would run. using and deleting tens of thousands of e-mails hillary clinton received while in office, she was using a private server that is now being investing. polls show the majority of people not only trust her but they're not excited about her campaign. that gives biden an opening. because he has seen as the exact opposite, trustworthy and honest in large part because of moments like this one when the president signed his president's signature health insurance. he's blunt. >> for god's sake, don't listen to rumsfeld. he doesn't know what in the hell he's talking about in this.

>> you're beautiful. >> his history is one that many americans can relate to. he was born to working class parents, and unlike clinton he is not worth millions. but there are some analysts who don't believe he can overtake clinton in the primary. >> i would bif anythinger those who get in now would be kind of throwing hail mary passes hoping that hillary clinton's stumbles further. >> a big factor could be who president barack obama endorses. he might weigh in. he won't say who he prefers. >> the president has described selecting vice president biden as his running mate as the smartest political decision he has made in his career in public service. >> biden has been a very public vp in charge of the stimulus during the recession and taking

point with congress on budget issues. he was also the lead on u.s. involvement in iraq. that could hurt him. as well as pushing for stronger sentences for drug offenses now a very unpopular stance. at 72 years old he would be the oldest president ever elected. one of the factors he'll have to consider, along with this, the dying wish of his son, who reportedly told him that he wanted him to try again, to run for president of the united states. >> patty culhane, al jazeera, washington. >> a popular spanish language variety show is coming to an end tonight after 53 years on the air. yes, saying adios to univision's saturday night extravaganza. sabado gigante is the longest running variety show in history.

it first came on the air in chile in 1962 and developed a loyal audience throughout latin america. in 1976 they moved to miami. now his real name is mario fresberger. his parents from german jewish holocaust survivors who fled to chile. >> struggling to get aid i aid to refugees. >> they have no shoes. they have no hats. they have no mittens. they have no winter coats. >> a photo of a dead child sparked more giving, and why much more help is still needed.

>> for aid organizations the refugee crisis in europe presents an unique challenge. people are coming in droves, and so far donations have not kept

pace the new call for action from american officials and what people can do to help. >> people are pleading to george the crisis has been dire for months now. >> these migrants are safe, but not everyone makes it this far. >> it was the image of a 2-year-old body washing ashore, as pool look for a safer home. >> they were going for a better life. this should not happen. >> the photo brought the crisis to light in a way that had not happened before. the world reacted. donations both material and monetary surged. >> we saw a baby washed up on a beach, and there but by the grace of god go our own children. i think for the first time we

woke up, and we said these are children. we can do something. >> caryl stern is the ceo of unicef. >> there are children on the run from war, poverty, violence. >> the non-profit organization has been helping since the syrian war began four years ago. when the photo went viral the organization saw a boost in donations by 600%. in the first few weeks the unicef funds brought in $1 million in donations. but that's not the response that other crises received. haiti earthquake received $50 million. >> america is not responding enough. >> when it comes to donating she can't give people a tangible goal because this crisis is different. >> this is the progressive crisis. people don't always understand what that is. so i've been out there screaming at the top of my lungs, look

what is happening, and people are just not hearing. >> some americans are listening. members of the islamic cultural center in new york donated truck loads of clothes, food, and some organizations say it is not cost effective to ship donations. they have alerted donors that they've stopped sending those types of donations. the best way to help is to go green. >> we can get it out to our colleagues who are responding on the ground. >> organizations are coming up with creative ways to bring in more fast cash. save the children worked with google to broaden it's reach. the search engine giant promises to match each donation with a goal to reach $10 million. >> the partnership is a key part of the way we mobilize the

resources we need to buy food, and to use cars to move items from the north side of the island to the south part of the island. >> without more money the futures are grim, particularly for the children. >> they're going to freeze to death in the winter. they have no shoes, they have no hats, they have no winter coats. there are no blankets. they have no food. they have no shelter. there isn't clean water. there isn't sanitation. those are all deliverable goods. >> unicef said it is 50% underfunded for the syrian crisis. the estimated need is another $500 million. this is where they're giving this plea for help aimed directly at american parents. >> as you look at your children tonight, how can you feel good if you're not giving some other parent the opportunity to do for their children what you do for your own. these are not refugees.

these are children. and they are counting on us to survive. >> and just to give a sense of what your money can do. look at this breakdown from save the children. $15 provides 1,000 gallons of safe drinking water for families fleeing their homes. $35 gives a child nutrition food for a week. $60 provides two families diapers, wipes and supplies for their children, and $120 provides leaping bags and a tent for a refugee family. a little bit can go a long way to help these people on their desperate journey. >> more than 300,000 refugees have crossed the mediterranean this year. italian photographer has focused his lens on their dangerous journey in a photo series from there to here. we hear from him tonight in his own words. ♪ >> the 2010 stories related to the immigration crisis in my

country, a work that tries to describe and to investigate about the road roles. the
