sports could be causing brain disease. more on the alarming new stud his ahead. welcome to have you as viewers. i'm linda kinkade and this is cnn newsroom. the pope had a strong message for its government. open up the world and give people the freedom and space to practice religion. it was a very windy day in havana when the proep arrived at the start of the visit. his warm greeting was -- including a salute, a marching band and bolts of lightning ♪ ♪ >> the cuban capital is the

first stoch on the pope's ten-day visit to cuba and then to the u.s. he's accredited with helping to restore diplomatic ties between the nations and he's urging them to stay on that course. >> the world needs reconciliation in this environment that we are experiencing. our political leaders to persevere on this path and to develop all its potentiality that's proof of high service. on behalf of peace and well-being of all america and the free world. >> the vatican correspondent judy gallagher is in rome and now joins us. >> we know it's very important to pope francis. explain to us the religious situation there. >> well, the interesting thing about cuba, lynda, is that because you've had a vacuum for

the past years in terms of religious instruction, the cuban people, many of whom are catholic and born and baptized catholic, nonetheless practice what they call the taking of elements from other religions and putting them all together in a third religion. one is one which comes from the african origin in cuba where the practice might be the sacrifice of animals or bringing fruits to statues. they may do this within a catholic church. they've combined different elements from the different religions. so the challenge for the catholic church even if and when they receive complete freedom from the cuban government as the pope asked for yesterday in his address at the airport to practice their religion is to then deal with the facts on the ground which is people who have not necessarily been educated in the catholic religion and who

practice a kind of melding of the different religions. so the challenge will be then for the catholic church to both reeducate a whole generation of cubans who don't really know a lot about the practices of the catholic church but at the same time respecting, of course, what's cultural tradition for cubans. that's the experience of several different types of religion combined into one. >> sitting alongside the pope yesterday, on these sort of trips, does the pope get to sit down and discuss issues with the cuban government? >> well, today they will have the official meeting between the pope and the president. it's about an hour long. that hour has to include exchange of gifts, a meeting of the whole delegation, a hello from the balcony. so in terms of actually sitting down and hammering out any policies, they have very little

time for that. it's not a trip aimed at that, because it can happen after the pope returns to rome. it's at the same time the pope is meeting with the president, the vatican secretary of state and others in the cuban government. they have a bit of time to talk about the key points. of course, the main point of those meetings is face time. that's important in any kind of negotiation. it is mainly a meet and greet. of course, we also know that pope francis likes to come away from these things with something. he likes to bring home something as he did when he went to the holy land and offered the leaders there to come back to the vatican for a prayer day. so i wouldn't be surprised if the vatican makes some suggestion, tries to bring some kind surprise out of those meetings, lynda. >> the pope does like a surprise. delia gallagher, thanks so much. we'll talk to you soon. the pope will be in havana until

tuesday. after that, he'll head to washington, philadelphia and new york in the u.s. we have more on some significant topics the catholic leader plans to talk about. >> the pope's visit to the u.s. was supposed to be all about philadelphia and family. but insert a stop in cuba, a cameo before u.s. congress and a speech at the u.n. and the visit could create a trinity of tension. first, havana where the vatican's influence helped to ease 50-plus years of animosity between the u.s. and cuba. >> there is a checkered and complicated past. but that's the past. the pope is about the present and moving forward. >> during president raul castro's meeting says -- he plans to attend every masel

brated by francis. pope francis told students in cuba through video conference, he'd like to see friendship between the u.s. achbd castro's communist nation. >> translator: one of the most beautiful things is social friendship. this is what i'd like to be able to achieve. social friendship. >> whatever the pope says in cuba will set the stage for a major address before a divided house in american congress. during his recent visit to south america, francis called capitalism the dung of the devil. but will he utter those words inside the nation's capitol? and what about those presidential candidates. >> we have to build a wall, folks. >> that charged anti-immigration rhetoric, polar opposite to the pope. >> i'm not sure if he's worried about alienating people. he'll be encouraging but he speaks the truth. >> his speech before the united

nations at a time hundreds of thousands of christians are fleeing persecution from iraq, afghan san and syria. will he put world leaders in the hot seat asking more to do to help refugees or praise the nations who have accepted thousands. no one knows what francis will say during his more than 20 speeches. if he speaks off the cuff, cuba, congress and the united nations better get ready for a coming to jesus moment. rosa flores, cnn, rome. you can stay with cnn for more live coverage of the pope's visit to cuba. we'll have special programming leading up to and including the pope's mass in revolution square beginning at 6:00 p.m. in hong kong. . we turn to europe where

hundreds of exhausted migrants reached austria after train rides and a long walk from hungary. more than 7,000 migrants arrived in austria from hungary since friday night. volunteers are on hand to give them food, water and other aid. hungary migrants are put on buses and sent to three registration centers in austria. arriving in austria has been a long time coming for thousands of the refugees and migrants. most of them are from the middle east to have traveled across the sea and through other countries. many say their final destination is germany. hungary will take in -- will not take in any other people. so the migrants, even those who want to stay put, are forced to go to austria. international correspondent ben wedeman walked with migrants in the dead of night. he said it's not clear what's next for the hundreds of tired desperate people. >> reporter: they arrived at the

train station dazed and confused in the dead of night. they didn't know where they were or where they were going. you're on the border of austria, i explained. to get there you have to walk four kilometers. the train had taken this group of refugees and migrants from the croatian border through hungary directly to here. no formalities and few amenities along the way. and on this last stretch out of hungary and into austria, a country that's welcomed refugees, neither exhaustion nor injury could hold them back. >> palestinian refugee from aleppo, syria had sent her children ahead with relatives to munich and germany. >> every step i take gives me joy she tells me because i'm getting closer to them. i miss them so much.

son a miles an hour in his arm, there's light at the end of a long tunnel stretching back to his homeland in ruins. i feel relieved he says even though the grueling nine-day trip from turkey left him penniless. despite what we've been through, i'm happy because we made it. >> as a last gesture before they stepped out of hungary, local aid groups waved them down with refreshments. after days, indeed weeks of frustration, false starts and closed borders, some good fortune and good food was finally abundant. these are the lucky ones who reached the promised land. they've arrived in austrian territory. from here on in, there's no guarantee that life is going to be easy. in fact, it's probably going to

be difficult. at least their journey is almost over. ben wedeman, cnn on the austrian/hungarian border. the migrants you saw journeyed with risk. most head out across the sea and a number of boats capsized during the dangerous trip. on saturday, various countries rescued more than 4,000 migrants in the mediterranean in 20 separate operations. we want to paint you a picture of what they're facing. in a recent rescue operation off the coast of greece. take a look. >>.

>> translator: we were -- i just know i didn't any hope. i said i'm dead right now. i'm dead. nobody found me. no police saw us. the greek police saw us and they didn't care. at that moment, we all thought that we were useless, we are not human. >> international organization for migration estimates that nearly half a million people arrived in europe by sea. this year so far. the senior spokesman for international organization for migration joins us by geneva, switzerland. thanks for being with us, joechlt we're seeing migrants pushed from one country to the next or trapped by a country and can't get through. how would you describe the situation? >> well, unraveling is one way to look at it or possibly

raveling into something more permanent. most of these people have been away from their homes for quite a long time. anywhere from three years in a refugee camp possibly up to a year on the road from their homes. it's a long, hard journey with other afghans crossing into turkey or syrian to take a long roundabout route. we've had this now since -- well, almost two years since the last tragedy in 2013. the total number of migrants who passed through europe at least since then is above half a million. well above that. we expect this to continue and continue to look chaotic to the outside world. but really it's moving towards a solution. >> of course, as the saying goes, fences don't make good neighbors. the prime minister has said, it will continue to send high grants to the borders.

that situation is a very -- it's a major flash point here. what do you make of that? >> i've always been an outliar on the eu for years. their biggest complaint was the 17,000 or so serbians and coes vars who would try to access hungary to get asylum applications or move on to germany. i was meeting with a turkish group and 17,000 was the number they could expect in a single weekend from syria. of course, when hungary thought outraged six months ago is much bigger. it's a combination of lofts different things. some of these countries are only one generation out from being part of a soviet dominated bloc. they have very heightened tension about their national identity and what's going to happen to them. many of their best and brightest left these countries for better jobs in uk and scandinavia and germany as they're entitled to

do under the eu. they feel threatened by that. unlike germany where they don't have a 40-year history of assimilating muslim fellow citizens or fellow residents, people on their workforce, these are things that will take time. they're extremely confident that all the countries will adapt but it's a big change for europe and has to be looked at that way. >> there's a huge change. it's unprecedented. the eu is so divided on how to handle this practice. an e.u. quota plan to share the burden. if they are f they aren't willing to budge, what needs to happen? >> that's a good question. i was in latvia last weekend. it's one of the smallest of the. they've been asked to take 500

or 700 asylum seekers or whatever they turn out to be. they consider this an outrage, it's something being forced upon them. would a country that small depend on charity really save -- forgo all the benefits of the eu over the issue of 500 to 700 migrants? i don't think so. i think we should expect this kind of resistance as a starting point. when they get back down to practices and how to manage the flow, i think a lot of the countries will find it's better to be part of the system and to participate. >> so you think those sort of threats might work? >> well, threats is not the wordy use. it's something that -- look, europe for two years has done a lot of finger pointing. why isn't greece or italy doing more to keep the asylum seekers to keep them where they belong because. but speaking, where they belong

is with their families. the families can take them in, provide employment, provide income and it takes the burden off the governments of all those countries. the argument that they should have stayed in italy or greece, nobody can rile accept that anymore. that finger pointing stage is coming to an end. the fact that some eastern european countries speak to the resistance of the quota the coming out of brussels. we've had much bigger issues before this. letting migrants drown as the most effective way to deter this. we think europe has evolved rapidly and towards a solution that will be the benefit to those coming and those neighbors that are come to go live there. >> joe, we appreciate you joinin us as always. thank you very much. >> thank you. cnn has gathered information on ways you can help the migrants in terrible need.

war ii would allow japanese troops to fight overseas in combat roles under certain conditions. in tokyo, it's called collective self-defense. here in pyongyang, they're calling it evil. listen to this statement from kcna. japan's mill tarrist moves are posing a grave threat to peace and stability in asia and the rest of the world. that outlet goes on to report that this situation proves that north korea is justified in bolstering and growing its military capability. now, all of this is coming as north korea is just weeks away from a major anniversary celebration. they're already trying to flex their military muscles to show the world just how strong and powerful they are. you can expect to see more rhetoric in the coming weeks. north korea also widely expected to be launching a saturday lie into orbit to showcase their --

it will be a clear indication of how far this country has come in terms of developing a long-range missile. a missile potentially capable of carrying a nuclear warhead which north korea says it has in its arsenal. keep in mind, japan once occupied the korean peninsula. that memory is still very much alive here. it's the reason, north korea says they must continue to invest so heavily in military capabilities to counter what they call a serious threat from the united states including a stronger threat from japan. will ripley, cnn, pyongyang, north korea. a rugby powerhouse felt the sting of defeat on saturday. south africa's lost to 13th ranked japan in a preliminary match. it was completely unexpected. the final score was 34-32. patrick snell has more about the upset. >> what a moment for japanese

rugby. what a desperately poor moment for south african rugby. it lost 34 points to 32. this is a key moment. going over dramatically to shatter the box. we think the images breathe ever so slightly look what it means. the emotions of this victory to players and fans alike. south africa had never before lost an opening game of the tournament. actually at this historic match. i spoke with him a short while ago. >> patrick, i've been privileged to watch a lot of sport, but i tell you what, this is up there with brazil losing 7-1 and all these incredible results we've seen. rugby needed this result. and japan came out firing on all cylinders. motivated by the support in the stadium. the new trals that came in were all supporting japan. they're certainly a well-coached

team by amy jones and astute on the field and knew what they wanted to do, set up a solid pac and what we all love to see, cavalier rugby. >> it was absolutely deserved. they went for it, didn't hold back and got the victory by two points. now south africa will have to pick up the pieces. meanwhile the tournament continues and for japan that means facing off against scotland on wednesday. greek voters are electing a new voft. just ahead the candidates and what's at stake. we're live from athens. in the u

putting an end to austerity, possibly an end to greece's bailout. all of that as the lead of syriza, signed the bailout. the question reallyow is who can best implement it and put greece back to a path of stability. i think this is really what greeks will be looking at had they go to the polls today. >> reporter: we're looking at a situation where this was an election that was only called a month ago. most of the issues have been dominated by the economy and who leads the country into the next steps. so when we're looking at assessment from the creditors, how the bailout is implemented, greeks want to see who will be the best person to really take them through this very difficult path ahead, lynda sniemts looking at the best person to to do that, the fact that he resiepd from this election, do

people have faith in you given the time he was acting on a -- >> the two parties, main parties are neck and neck. this is not something that vetted when he called the elections a month ago. he did lose the support of quarter of them over the bailout. he said he was taking a gamble when he called this election in the sense that he wanted to call it early enough for people not to have really felt the pain yet of the new austerity measures that are about to kick in. it seems that in this month, the main opposition has risen in support and that's why greece finds itself today in the situation where we're really looking at a resolve to -- still really impossible to tell. it's within the margin of error of 3% and all those cities slightly in the lead, it's difficult to tell whether he'll be able to pull this through.

>> we'll have to wait and see. thank you for your analysis. talk to you soon. greek's economic turmoil has been especially hard on the country's young people. here's one voice from the so-called lost generation. a young man who once had a very bright future. now he's getting ready to leave greece. >> my name is -- i'm 29 years old. i currently live in athens. i couldn't finish my master degree because of the economic crisis hit us like really hard and i kone afford to pay for my mother or my house or for anything. right now, where i'm currently

sent today were very significant. for the first time we are hearing from donald trump. he's fighting back a different way. i want to read a few tweets saying "this is the first time in my life that i have caused controversy by not saying something." later tweet, if somebody made a nastier controversial statement about me, do you think he would come to my rescue. it's interesting we're at the mackinaw conference here on mackinaw island. this is a lot of the buzz here. a lot of people waiting to see many of the republican candidates. whether they will address this or not, we got out of a briefing with governor kasich of ohio. afterwards, he said i'm not going to focus on donald trump. even when we pushed back and said doesn't a leader need to correct the record if a voter says something that is wrong. interesting to see how it will develop at this republican.

many arrived taking great lengths to get here, some by ferry. this island doesn't have cars or transportation. they have to take a horse-drawn carriage. certainly interesting entrance by many of the candidates. we heard from jeb bush who mentioned the donald trump comments and he said point-blank that president obama it a christian. president obama is an american. >> trump responded further by answering questions about his views on muslims. he took part in a question and answer session with iowa high school students on saturday night. >> i consider muslim americans to be an important asset to our country and society. would you consider putting one in our cabinet? >> consider what? >> putting one on your ticket or cabinet? >> muslim, absolutely. no problem with it. would i consider a muslim american in my cabinet, absolutely no problem with that.

okay? >> trump also told them, i love the muslims, i think they're great people. the national football league is working to make the game safer with more medical checks and rule changes. the game is of course, very rough and down right brutal at times and head-on collisions are frequent. new research from the u.s. government in boston university show 87 of 91 forr players tested positive for a brain disease. that disease is associated with repeated head trauma. our chief medical correspondent, sanjay gupta, he spoke to anderson cooper about the study and how the disease probably isn't limited to just nfl players. >> cte, chronic traumatic i can encephalopathy, it's a brain disease and a progressive one. it's twhaun typically gets worse and flares in people who have it over time. it's one of these things that really people have started

hearing about it over the last few years. the research started in 2008. i got to tell you, i was at that lab in 2011. even at that time, no one was really paying much attention to this. what they now know when examining these brains, many of them of former nfl players, they're finding evidence of the proteins in the brain that are deposited within the brain itself that very much looked like alzheimer's disease. that's what has really gotten people's attention. people, when they're living with cte, while still alive, they oftentimes have memory loss, problems with depression. problems with anger. it is when they die, though, that the diagnosis is conclusively made. >> cte isn't necessarily just from the really violent hits on football field. it can be from smaller incidental contact as well, right? >> yeah. absolutely. they believe that there's concussions which a lot of people have heard about but also sub concussive hits.

those are the hits that could be as problematic as the concussions. concussion gets all the attention and concussion, that term each, probably shouldn't be used anymore because they're all brain injuries that we're talking about. the sub concussive hits where the player doesn't make anything of it, nobody pays attention to it, the damage can accumulate over time. that's what the scientists told me. they've never seen cte in a situation that didn't involve blows to head. from football or other sports as well. >> it's not just football. it could be soccer, is this in older people or high school players as well or younger? >> what they find is that typically younger people tend to be a bit more vulnerable to this. their brains are still developing. the repeated blows have more of an impact on younger people's brains. girls soccer is another one.

last week, i was with a young woman who was playing soccer for some time. developed signs and symptoms that might be consistent with cte and it's really been very devastating for her. it can happen in soccer from people heading the ball over and over or head to head collisions. basketball even. typically girls in most of the sports more likely to suffer these concussions than boys. it could be that the neck strength isn't as strong. they're more less to report them. girls can be affected by this as well. again, the concussions, what it leads to ultimately is what the cte study is all about. >> that's probably scary. sanjay, appreciate the reporting. thank you. that was dr. sanjay gupta. researchers say the players who donated brains to be studied upon their deaths already had concerns about cte while they were alive. it is possible the results of the study are skewed. right now cte can only be diagnosed after death. best selling novelist jackie

after week of deadly flash

flooding in the western u.s. state of utah. the potential exists for potential heavy rain in the u.s. this week. let's bring in our meteorologist for more information. how much rain are we talking about? >> several inches of rain over the next three to five days. near the border of arizona and utah, on tuesday this week, there was flash flooding that unfortunately led to roughly about 20 fatalities in a few different incidences including at zion national park and the hilldale community. what you're looking at to my left here is some of the home footage of the mudslides that occurred because of the water rushing down the canyons. take a look at my graphics. we're focused in on the southwest. just a bit of geographical reference, the baja of mexico, california, arizona and utah. this bright shading of coloring, that's actually the moisture starting to settle in to the southwestern portions of the

united states. that's going to be eventually moved further and further northward impacting the southwestern u.s. that's going to bring the possibility of heavy rain and flash flooding exists across this area. remember, we're under a four-year drought in california. and even into southern nevada, parts of arizona as well. the ground is extremely hard. any time we get these slow-moving thunderstorms moving across this region, they dump so much rain with the ground so hardened as it is, it doesn't have time to soak in. it finds its own level, culminates in the valleys and crevices and eventually culminates into a flowing wall of water leadsing to the possibility of dee strugs like this. wiping out anything in its path. including vehicles across roads. this was a situation in hilldale near the border of utah and arizona. the rainfall just culminating in

the top of the mountains, cooling down the canyons and rushing towards, seeking a lower level. and it could lead to dangerous scenes across the area. we want people to be aware this is a possibility going forward. something we'll pay close attention to in the cnn world weather center for the possibility of more flooding into the southwestern u.s. over the next several days. you can see the rainfall moving in. in fact, anywhere between 2 to 5 inches of rain and that is more rain than they have seen in a very, very long time. >> really worrying for the people traveling there as well. >> people need to be aware of their surroundings. the slogan the national weather service uses, turn around, don't drown. if you see moving water on the roadways, it's not worth it. >> good advice. this is a story you might want to stick around for. we want to leave you with amazing photos of the milky way. it's from one of our reporters. the images were taken while on a

trip with his wife in the u.s. state of arizona. he said he did a little editing to boost contrast and bring out the details in the photos. other enthusiasts tell us it's amazing to be under millions of stars and see how stunning it looks. >> it is very spectacular. those photos are incred blg. we don't get the luxury of seeing that amount of star-filled sky in atlanta. so unfortunate. you've got so many city lights. so many buildings. >> that's actually called visual light pollution. so what you need to do is step away from a city. >> get out in the bush. >> get out into the bush. a remote area and look up into the sky to see that. you know what, the milky way has over 100 billion stars. >> beautiful pictures. good to chat with you, as always. thanks everyone for joining us
