i have lived in the city for years, but hong kong still makes me fall in love with it time and again. >> and now, "bbc world news america." katty: this is "bbc world news america." reporting from washington, i am katty kay. the personnel records of islamic state. thousands of documents showed names and addresses of those who signed up to fight. president obama gives a warm welcome to canada's new prime minister justin trudeau. a woman in south africa is found a days oldidnapping baby. you won't believe how the truth was discovered.

welcome to "world news america." the personal details of more than 20,000 islamic state fighters have been leaked. the files were obtained by german and british media organizations and appear to be recruitment questionnaires. they reveal the fighters' names and addresses. they were handed over by a disillusioned member of the group. gordon carrera has more. gordon: the group calling itself islamic state has drawn in thousands of recruits from around the world, including many from britain, and now a unique insight has emerged into who joined and how. it comes in these documents, smuggled out by a former member and obtained by some media organizations. the bbc has seen only a few of them, but they look to be personnel records, effectively application forms for those who

arrived in iraq and syria. the questions range from the standard, name, date, and birth, through to, who has recommended you, have you done jihad before, and do you want to be a fighter or suicide bomber? the german government today confirmed it had received a copy of the files. >> in the opinion of the security services, these documents are in all probability authentic. they show how conscientious this criminal organization is and how effective it is. gordon: the documents are reported to include details of 16 britons, including those killed by drone strikes. hundreds more britons have gone out, and these documents are only thought to cover a period from late 2013 into early 2014. the security service are not making any comment on these

documents, but the british authorities are thought to have been passed a copy, and if they prove to be authentic, they could be a source of valuable intelligence. a former intelligence officer says the documents could help find those who have tried to evade authorities. >> clearly, they will support investigations particularly into people who have come back home and made deny that they were ever members. it's much harder to do that, because clearly, although these records have not been authenticated, they look kylie jenner and -- genuine. gordon: is may aspire to act like a state come even having its own personnel department, but in this case, the desire for record keeping could prove to be its weakness. some tension in

the britain-american relationship. barack obama has been surprisingly critical of david cameron. at one point, he warned the british prime minister but the uk's low level of defense spending, telling mr. cameron to pay his fair share in order to preserve the special relationship. nick bryant has more. ♪ the whitehe lawns of house this morning, signs of a special relationship in the making as barack obama welcomed the canadian prime minister justin trudeau to washington. a few years ago, david cameron was the recipient of the same pomp and circumstance, but judging by an interview the president has given to "atlantic," relations between these allies across the pond have lost some of their luster. at last year's g-7 summit, the article claims the president told david cameron, you have to pay your fair share in defense spending for the special relationship between the united

states and the u.k. to remain intact. perhaps that explains the awkward diplomatic body language between the two, or why britain committed shortly afterwards to spending 2% of gdp on defense. another bone of contention, the chaotic aftermath of the live -- the military's intervention in libya. libya is now a mess, according to mr. obama. privately, he said to have used expletives while acknowledging american blame. he said he had more faith in the europeans and that david cameron got distracted by a range of other things. >> it's unusual for an american president to have distance from a british prime minister on a major security issue. i suppose mr. obama was being contemplative and historical. he perhaps thought he was looking back on a broad trend.

nick: the criticism over libya is unfair, according to a former british foreign secretary. >> its rich for the president to be singling out britain or any other country. britain and france did most of the air operations and were much more heavily involved in even the united states on this occasion. than even the united states on this occasion. nick: the obama administration's gripes with downing street do not end there. britain seems to be hedging its bets on which country will only century in terms of global power. david cameron has prided himself on the closeness of his personal relationship with barack obama. they were barbecued buddies in the downing street garden, so u.s.unusual for a president to combat a british prime minister.

president obama complained of free riders in the international community, and britain was in danger of falling into that camp, but with downing street boosting defense spending, there has been a concerted effort to address that complaint and repair the coveted special relationship. the white house said tonight that britain has stepped up on a range of issues. nick bryant, bbc news, washington. katty: a relationship that london watches closely indeed. this bump in relations with britain comes at the same time that the white house is rolling out the red carpet for the new canadian prime minister justin trudeau. he joined president obama for a news conference in the rose garden, and they discussed issues like climate change and trade. tonight, it will be a state attendeesd among the will be democratic senator amy klobuchar from minnesota. she joined me a short time ago. it seems to have been a bit of a lovefest between these leaders. does justin trudeau remind you of barack obama when he came

into office in 2009? sen. klobuchar: i think there is a shared element of change. both of them ran on change. the president would tell you he's got more gray hair then -- than trudeau. they both came in as somewhat unexpected forces. when you go back to the beginnings of their elections, i don't think people anticipated they would win. it's been digging in the trenches on issues like softwood lumber and ballast water, and suddenly, i have become cool. it's glamorous. we hope that continues. it is such an important trading relationship, the biggest one we practically have. people overlook canada, and they shouldn't. katty: i'm sure you were always cool, but there were issues of substance raised, and one is that of borders.

could mexico be forgiven for what is happening in washington today, there are the canadians getting a more open border, while some politicians in america are talking about putting up a wall between mexico and the u.s.? the only terrorist we know who has tried to come across the border came from canada, not mexico. sen. klobuchar: one republican presidential candidate, governor walker of wisconsin, did entertain the idea of building a wall with canada. let's say he got out of the race about a week after that. we have had security issues, not nearly what we have seen with mexico in terms of the issues at the border, but there have been security issues. we have upped our game since 9/11. i can sit canada from my porch. you could use a drivers license to get over. now you need a passport. the focus on canada right now is to try to improve our flow of commerce, including get a -- getting a better situation between windsor and detroit.

both countries have agreed to build a new bridge. the airports, better preclearance, so passengers can fly from canada to america, and then the infrastructure. mexico, we have had more private investment at some of the border controls, and it's a good model if you want to up your game when it comes to infrastructure at the border. katty: another issue you have spoken about in respect to canada is their reception of syrian refugees. i was wondering given the numbers and how few syrian refugees have been settled in the u.s., does canada put the u.s. to shame? sen. klobuchar: i don't think they put us to shame. i would say they have taken this up as an issue, and i hope it will work to convince some of my colleagues that as long as you have a proper vetting process in place, we should be opening our doors to legal refugees who have been vetted.

when the prime minister just after he got elected went to that airport and welcomed those refugees, he set a symbol for the rest of the country. it wasn't just words. canada has taken in 25,000 syrian refugees with at least another 10,000 to go this year, and the u.s. has not done as many. i'm hoping it sends a message. my state is a home to so many refugees. we should be taking in some syrian refugees. katty: many of those refugees are coming from syria, and we are marking five years since the start of the uprising. tonight, we report from the city of dara, the cradle of the syrian uprising, the place where demonstrations erupted during the arab spring.

the situation in syria has turned into an increasingly brutal war. has returned for this report. lyse: the road is deserted. our police escort speeds us past this blighted landscape, the battle for syria. it started here. graffiti sprayed on this school wall called on president assad to go. teenage boys, arrested, allegedly tortured. anger boils over. the first major protest happened here. this mosque, a focal point. the first deaths in the city, too. security forces struck back. a few months later, we were among the first journalists there.

the mosque was eerily quiet. no one dared to speak. the governor i saw them is still here. his compound, more heavily fortified. he takes us up stared -- upstairs. last summer, the rebels attacked. it was the biggest offensive by western-backed rebels to take the city. he reflects on his five years here. >> we might have made some small mistakes here and president assad talked about that. since day one, our leaders told us it was a conspiracy. if there was a need for change, why did they destroy the country? their revolution destroyed it. lyse: a city divided. we drive to the last military checkpoint. the buildings in the distance are in rebel hands.

we are told we can't go any further. even with a truce, there is a distant rattle of gunfire. we spoke to a teacher on the other side by telephone. >> [indiscernible] lyse: when the protests began, some syrians dared to believe that political change could be as quick as in egypt and tunisia, but the dream of the arab spring died here. over the past five years, the protests have evolved into the most brutal of wars, so much so that many now fear that syria itself could be lost. on the other side, the university, once a focal point of protests.

it is a different place now. many teachers and students have left. >> we came here in the middle of bloodshed, bullets. lisa: he tells me most of his friends are in germany. >> if we went there, we will have lost. lyse: you have a future in syria? >> i believe syria has a future. we will get up again. lyse: in syria now, a rare moment of calm. people want the truce to hold. they can't let go of what began five years ago. they know it is still not over. katty: people who desperately deserve a moment of calm.

still to come, going inside the exclusion zone, five years after the disaster of fukushima. some areas are still off-limits. as the republican presidential candidates battle it out, the idea of a brokered convention is being raised. what would that look like? here is an idea. >> the race to the white house has been a mad scramble with all of the candidates scrapping for votes, and at times, it has seemed like child's play. >> the action is nonstop and frantic. win a caucus or primary, and you get delegates to the national convention. >> donald trump has the most so far. on the other end, john kasich has hardly any, but mr. trump doesn't have enough to secure the nomination. >> the magic number is 1237.

if he wins that, he wins the nomination. >> if he can't, we enter a scenario known as a brokered convention. in essence, it's a political free-for-all. >> all the delegates are thrown back into the mix, and the game starts over. >> all the delegates you would want don't matter, and it's down to old-fashioned haggling to win back those delegates. >> these brokered conventions used to be the norm. >> swapping rumors of deals and counter deals. >> it would get acrimonious, and sometimes it would take days, even weeks to settle on a nominee. >> alabama's democratic delegation strides on the convention hall, followed by the mississippi delegation. >> in a mad scramble for delegates, anyone can come out on top. it could even mean john kasich wins the most. maybe he has done the most arm-twisting.

>> donald trump isn't going to go down without a fight. >> given that the establishment is against him -- >> this could come down to a good old-fashioned bar brawl. katty: i love that, everything ago, andears earthquakes parked a massive tsunami, which triggered the shutdown of the fukushima nuclear plant. hundreds of thousands of people were moved from the northeast of .he country almost two thirds of them are unable to return because of fears of high radiation levels. rupert wingfield-hayes sent us this report from inside the exclusion zone. rupert: five years after the nuclear disaster, there are large areas where people are not

allowed to return home. this is one of them. this village is about 10 kilometers from the plant, and there is no plan for people to be able to return here for the foreseeable future because this is been declared a high radiation zone. he first measures the radiation levels around his house. this spot is especially high, he tells me. the rain washes the radiation off the roof, and it collects down here. is more chaotic every time he returns. he thinks a wild boar has broken in and turned the place upside down.

seeing all of this rekindles his feelings of anger about what has happened to his home. i hope my ancestors will forgive me, he says. it's not my fault i cannot return here. i had a deep attachment to this place, and if i admit that, it hurts too much. this is part of his pottery workshop. these were the shelves where he would stack all the pots and cups ready to go in the kiln to be fired. these are the kilns where he fired his pots. his family has lived here for 18 generations, more than 300 years , and now it has all been lost, and probably, they will never return. betweenthe difference biological and his logical half-life? is it too dangerous to return?

professor jerry thomas thinks not. she is one of britain's leading experts on the effect of radiation on the human body. me into the with exclusion zone to show why she thinks the danger is overstated. >> at the moment, it wouldn't be safe to come back. radiation, the amount of radiation we are getting now is very small. if you stood in the open air all move, then you would be getting a little extra each year. if you had a ct scan, it would there. thomas isn'tssor alone. many nuclear experts say the exaggeration of the danger from radiation is making the human

.ragedy at fukushima much worse rupert wingfield-hayes, bbc news. extraordinary images from neare the exclusion zone fukushima. a south african woman has been found guilty of kidnapping a newborn baby almost 20 years ago. the girl was snatched from her mother's bedside in hospital three days after she was born. most amazing is she was reunited with her family last year after she made friends with a younger girl at school who turned out to be her sister. karen allen has this story. karen: a living nightmare for any mother. this woman's baby, stolen from her hospital bedside just days old. now 20 years later, justice. the woman who snatched her baby, convicted at last. it was left to the child's biological grandmother to speak on behalf of the family. >> we are not going to force her.

we are going to say she must come. karen: for years, her biological parents who went on to have other children celebrated their missing daughter's birthday every year, never giving up that they would see her once again. then at school last year in a remarkable twist of fate, their daughter befriended a girl who looked just like her. dna tests proved it was his fma. extraordinary was that here, a short distance from the home, the woman who kidnapped the baby all those years back. today before she was convicted, the woman who can't be identified told me she was sorry but claimed that the girl now uses a different name. what is so astonishing is that her own husband never knew the truth. >> i believed she was my daughter.

karen: throughout the case, the 51-year-old accused that the baby girl had been given to her by a stranger. in convicting the accused, you have a history of miscarriages, the judge said he was astonished at her conduct. he said her story was a fairytale. she deceived everyone including her husband. you don't have to be a rocket scientist, he said, to know that you can't buy a baby in south africa. now a young woman getting on with life, how she will be affected by this extraordinary turn of events is impossible to imagine. karen allen, bbc news, cape town. katty: that's the real story and tragedy. you have to wonder what the girl is going through after all of that.
