emotional prince charles was there. it was a big, the day. now, 20 years on, we are seeing hong kong celebrate that handover and carrie lam, as well, being sworn in as the new chief executive. you can see many people they are. let's cross now to our correspondent juliana liu, who's in hong kong. what can we expect from this ceremony? i am locatedjust a what can we expect from this ceremony? i am located just a short stroll from the convention centre where the inauguration is due to ta ke where the inauguration is due to take place. the chinese president is in town. the 20th anniversary of hong kong returning to china. carrie

lam will be the first woman chief executive of hong kong and at the fourth person to hold this position since 1997. her background is as a career civil servant not she started out serving in the colonial civil service. working herself up. she was previously a popular civil servant but five years ago, when she started serving the current chief executive, as his deputy, her reputation has become much more divisive. she is 110w become much more divisive. she is now a polarising vigor seen very much as a beijing loyalist and that reputation will make it difficult to do as she has promised to heal divisions in society. it is difficult to see how she will do that given the perception now. we

can see pictures of carrie lam. it appears she has been sworn in. president xijinping appears she has been sworn in. president xi jinping and appears she has been sworn in. president xijinping and carrie lam 110w president xijinping and carrie lam now shaking hands. quite a momentous occasion. how is it viewed in hong kong? is it bad celebrant —— celebrant moment? people that will be celebrating but outside it is a com pletely be celebrating but outside it is a completely different picture. i am standing just a short few minutes walk from that location butjust standing just a short few minutes walk from that location but just an hour ago this area was full of pro—democracy demonstrators, scuffling with police, as well as pro— beijing loyalist. three groups

scuffling behind me. they have been trying to walk peacefully to that so remaining, the pro— democracy protesters. asking for the release ofa protesters. asking for the release of a dissident imprisoned but before they went to do that, scuffles started with police seemingly without any kind of warning. then pro— beijing demonstrators came flying the chinese flag. it is finished now but about an hour ago it was still quite intense and it only ended when police took away the leaders of the pro—democracy protests. we are still watching these live pictures. you can see carrie lam and president xijinping.

this looks like her cabin at being sworn in as well. that was also due to happen. this is quite a big moment for the people in hong kong. more so because it falls on the 20th anniversary of the handover of china from britain... apologies, hong kong from britain... apologies, hong kong from britain... apologies, hong kong from britain to china. andrew fung is the director and ceo of the hong kong policy research institute and joins me now. thank u forjoining me. can you give us thank u forjoining me. can you give usa thank u forjoining me. can you give us a sense thank u forjoining me. can you give us a sense of what carrie lam's challenge is going to be known as the chief executive of hong kong?” think the next five years are very crucial for the future of hong kong. the presidency came at a very important moment and the president

gave a positive message. he is appealing the political and business leaders to unite and support carrie lam and to enforce her social harmony. social harmony he put in a very important position that the whole society of hong kong, is appealing to the people to have faith in themselves and to... and to find a solution, problem—solving attitude, to the many problems of hong kong, instead of acting in notionally to the problems. —— emotionally. saying that social harmony is very important. that undoubtedly is the major task of carrie lam that the society is less divisive and more harmonious. president xijinping divisive and more harmonious. president xi jinping also said... sorry, andrew, there were

conflicting messages that the 1—party to system is historical and no longer relevant according to the foreign secretary. the joint declaration is what talking about. that it has no practical meaning at the present time. how committed is president xijinping the present time. how committed is president xi jinping and the present time. how committed is president xijinping and china to the autonomous rule of hong kong given those sorts of statements? but of course, because of the spirit and major turns for the signing of the joint declaration are in the basic law. what the central government is saying is that we have the basic law. the declaration is 20 years

ago. it is a national agreement. i do not think the beijing government is saying we will not recognise the importance of the declaration but now we have the basic law. we did see some pro—democracy protest occur in in the last 2a hours, how big is that it pro—democracy and pro— independence movement in hong kong? at present, according to many surveys , at present, according to many surveys, the most important concern of the people of hong kong is on housing, property and development of young people, whether they have good prospects and so on. political reform is important but it does not mean that the people of hong kong do not ask for elliptical reform. the general wish is to have the chief

executive and legislation directly elected. —— political reform. right now, in the coming years, the major concern is to bring back harmony so that there will be a better conditions to restart discussion on political reform. i am sure carrie lam has her work cut out for her. thank you very much for your time. we are seeing president xi jinping with carrie lam. so remaining taking place. that swearing in has taken place. that swearing in has taken place. carrie lam is the new chief executive of hong kong. she is the

first female to hold the post. she isa first female to hold the post. she is a career civil servant. 60 years old and a roman catholic as well. we will keep you up—to—date with developments as many events can be new in hong kong to celebrate 20 yea rs new in hong kong to celebrate 20 years since the handover from britain to china. two other news... the time for patients is over at cording to donald trump with regards to north korea. he called to a determined response to the nuclear threat posed by north korea but has also looked at sharing the coast of trade and fairer trade. this was the visit of a strong and historic ally at a time

of uncertainty, with a recently elected leader and an unpredictable one. it was the first foreign visit for president moon. the interest back home spurring an eager scramble for the best shot. easy, fellas. hey, fellas, easy. perhaps a bit over eager. fellas, easy. the two men took each other‘s measure on the crucial topic of north korea. mr moon wants to engage the regime, mr trump wants to isolate it. but they emerged from their discussions calling for a determined response. the us president pressing for tighter sanctions to force north korea to end its nuclear weapons program. our goal is peace, stability and prosperity for the region but the united states will defend itself. always will defend itself — always. and we will always defend our allies. as part of that commitment we are working together to ensure fair burden sharing in support of the united states military presence in south korea. mr trump took aim at defence

spending and unfair trade practices — he was very blunt about that. but for the south korean president, security in a dangerous neighbourhood was the main issue. translation: president trump and i agreed that only strong security can bring about genuine peace. we concurred to strengthen our overwhelming deterrence. mr moon threw in a line about dialogue with north korea but he did not emphasise it. both men are relatively new in office and they agree that they are facing a growing and significant threat from north korea. so despite their differences in approach, they chose to use this first meeting to show a united front. president trump hasn't ruled out talks with north korea but given what's happened to otto warmbier, that prospect has become even more distant. his death after captivity has hardened attitudes here. the two presidents agree that china is key, like south korea, it advocates engagement but the us wants it to put the squeeze on north korea by cracking down on sanctions busters.

washington did so itself, this week, penalising a chinese bank. the threat may be in south korea's backyard but it is the us protector who is setting the course for dealing with it. barbara plett—usher, bbc news, washington. stay with us on bbc news, still to come: as hundreds of thousands of people prepare to gather in the canadian capital to mark the country's 150th anniversary, we'll be finding out why not everyone is celebrating. china marked its first day of rule in hong kong, with a series of spectacular celebrations. a huge firework display was held in the former colony. the chinese president, jiang zemin, said unification was the start of a new era for hong kong. the world's first clone has been produced of an adult mammal.

appointed chief executive of hong kong has been sworn by the chinese president. she is the first woman to hold hong kong's top post. and the chinese and hong kong flags have been raised in a ceremony to commemorate 20 years of chinese rule in the the iraqi army says it will announce the recapture of mosul from so—called islamic state within the next few days. but for the moment fighting remains fierce, and the situation for civilians still trapped in the old city deteriorates further. our correspondent nafiseh kohnavard has travelled to mosul and spoken to families who've fled the fighting, after being used as human shields. after nine months of fighting, there is now celebrations. the iraqi flag raised over what is left of the historic al—nuri mosque where the leader of the so—called islamic state once declared himself the ruler of all muslims. the security forces are close to pushing out the militants but the fighting is not over yet. the battle for old mosul continues.

just 500m away from us in this direction, the areas that the militants occupy is getting smaller and as this happens, rescuing trapped civilians becomes extremely challenging. this is one group that managed to find safety. these children were held as human shields by is. most of them were living in an orphanage but the militants moved them closer to where the fighting was taking place. they are tired and hungry. transported here as is occupied their villages. the iraqi forces are now moving them out of the old city.

the children are now being looked after by aid workers in a camp outside mosul. they will be safe but like so many here, the future remains uncertain. in new york a gunman who opened fire at the city's bronx lebanon hospital has killed himself and one other person. the shooter, a former employee at the hospital, also wounded six others — five of them seriously. police say he hid an assault rifle under a lab coat. the mayor of new york called the incident a tragedy of the sort seen around the country but this time, it occurred in a hospital: i want to say at the outset thank god this was not an act of terrorism. it is an isolated

incident. it appears to be a workplace related matter but that makes it no less tragic nor horrible. one doctor is dead and there are several doctors who are fighting for their lives right now. amongst those who were wounded. as you know, the shooter killed himself, not before having done horrible damage. our hearts go out to the family of the doctor who passed away and we stand in solidarity with the families of all those who were wounded and fighting for their lives right now. let's take a look at some of the other stories making the news. india is introducing sweeping tax reforms, described as the biggest since independence seventy years ago. they will streamline

it's a nation that thrives on diversity and which welcomes tens of thousands of refugees every year — but not everyone is celebrating the country's milestone, as our chief correspondent gavin hewitt reports. the start of a long weekend party. canada has begun celebrating its 150th birthday. cheering. millions of people expected to salute a young country, that unashamedly roots its identity in multiculturalism. canada to me means home, obviously, but it means diversity. we're very accepting of everyone here. diversity, different views, different minds, everything. why do all these celebrations matter? canada finds itself in the spotlight, astride one of the great faultlines of the moment. its prime minister, justin trudeau, has become a standard bearer for liberalism, in stark contrast

to his neighbour to the south, donald trump. justin trudeau made a point of going to the airport with warm clothing, to welcome syrian refugees. a school gate in toronto. gaghader and hamzeg pick up their children. not so long ago, they were fleeing homs, in syria. gaghader is at college, and hamzeg is already a taxi driver. canada wants them to feel canadian as soon as possible. somebody asked me, you like canada? i tell him canada is the best. canada's the best for me. my neighbours, the street, anywhere, they ask us where we are from. "0h, welcome, welcome!" and they help — what do you need, if we want help. but canada cannot escape the scars of its past. these are the lands of the iroquois,

building their traditional longhouses. some indigenous groups, native canadians, are boycotting the birthday celebrations. for many, the past 150 years have seen lands taken and promises broken. we were here — we look back further than 150 years, because we've been here for thousands of years. and you think canadians are celebrating, well, not everybody who lives in this country is celebrating 150 years of canada. the first nations people aren't. and then there is the british connection. today, prince charles was in the small town of wellington, beside lake ontario. one day, if things remain as they are, he will be canadian head of state. many in the crowd here want to retain their british ties. but elsewhere, some are less sure. at this anniversary, canadians are celebrating their history,

but these are uncertain times. they seem on a different path to their friend and neighbour to the south, the united states. it may prompt canada to be assertive in promoting its own identity. gavin hewitt, bbc news, canada. let's just take you back to the scene in hong kong where we have been seeing a ceremony where carrie lam has been sworn in. she is giving a speech at the moment. the chinese president has been attending. it is his first visit to hong kong since becoming president and he is believed to be leaving shortly after the ceremony. there is going to be a day of lavish celebrations because hong kong is marking 20 years since

the colony was handed over to china asa the colony was handed over to china as a territory. the deal was that one country, two systems and there has been much controversy over how much china has stuck to that deal and how much autonomy hong kong has. there is a lot to come there. well, saturday does not look bad at all across most of the uk. we're certainly in for some sunshine and some warm weather. there is a little bit of rainfall on the way in the north—west, but it shouldn't be too heavy. now, in the short term, actually a fair bit of cloud out there, and some light rain. damp weather just across east anglia in the south—east to end the night. many northern and north—western areas actually a lot clearer, so this is where we're going to have fresher weather early in the morning. in fact, in parts of northern ireland, maybe even in ruralareas, a touch of grass frost. and most of the temperatures

in the towns and cities will be 10—14 degrees there in london. let's have a look at the weather across northern areas first of all. this is first thing in the morning across scotland. looking absolutely fine, and the sun should be out. the clouds are increasing in the western isles and we've got some light rain heading to stornoway. that will push into scotland and northern ireland a little bit later on. but dry in belfast at 9:00am in the morning. notice that, maybe apart from the western fringes of wales, here in cornwall, there is a fair bit cloud around. but it will be mostly thin cloud and through the morning into the afternoon, those clouds will be breaking up and we really are in for a decent day. and see the sunshine there developing as that shade melts away. but at the same time we've also got a weather front getting into scotland and northern ireland, so around the middle of the afternoon i think there will be spots of rain in belfast, possibly glasgow too. so here, coolest around 15—17 degrees, but where the sun comes out for any lengthy period of time there across england it should get up to 20 degrees, maybe even 2a in london. how are we doing compared

to the rest of europe? well, temperatures are similar across the heart of europe, but incredibly hot across the south—east of europe. in athens, for example, 43 degrees there for some of our holidaymakers. so that is europe. back to the uk, this is saturday night. the damp weather in the north—west that i talked about will be moving southwards during the course of the early hours of sunday. so that means that, early on sunday morning, there could be some damp weather across east anglia, the south—east, but it should clear out of the way, and then basically we're left over with a very decent sunday once again, with some sunny spells. a little bit fresher, low 20s in london, around 16 in glasgow, but there's also some showers in the forecast there too for northern scotland. and then sunday into monday, weatherfronts are moving in, so there is a little rain in the forecast for early in the week. that is the weekend. so let's look at the weekend summary, then. it's not looking bad at all. a lot of dry weather, there will be some sunny spells, and it's going to feel pleasantly warm. this is bbc news, the headlines:

hong kong's newly appointed chief executive carrie lam has been sworn in by china's president xi jinping, she is the first woman to hold hong kong's top post. and the chinese and hong kong flags have been raised in a ceremony to commemorate 20 years of chinese rule in the former british territory. president trump says years of strategic patience with north korea have failed and are now over. with south korea's president moonjae—in at the white house, he said the menace of north korea should be met with a determined response. the iraqi army says it will announce the total recapture of mosul from the so—called islamic state group, within the next few days. but fighting remains fierce, and the situation for civilians still trapped in the old city deteriorates further, in the searing summer heat. now on bbc news, the week in parliament.
