welcome to bbc news, i'm reged ahmad. our top stories: clashes in hong kong after one of the biggest marches seen in the territory against a new extradition law demanded by beijing. more violence in sudan as three people are reported to have been killed on the first day of a campaign of civil disobedience. one of the leading contenders to become britain's next prime minister admits committing a crime when he took cocaine 20 years ago. and meet the seoul survivors — the dogs whose owners are trying to protect, from the city's choking air pollution.

hong kong's police chief says his force will bring to justice those who participated in violent clashes that followed one of the biggest marches in the territory, in recent history. organisers say as many as one million people took to the streets on sunday, to protest against controversial new extradition laws. the authorities put the figure atjust under a quarter of a million. our diplomatic correspondent james robbins reports. late into the night, a series of clashes between hong kong police and protesters determined to resist what they see as further erosion of their already limited rights. after a peaceful day, a far more troubled evening. some demonstrators piled high metal barriers, and pushed them towards police surrounding hong kong's legislative council building.

it is here that a widely despised new government bill will be debated in coming days. it would allow certain suspects wanted in mainland china to be sent across the border for trial. there were injuries on both sides. protesters threw missiles at police using batons, pepper sprays and high—pressure hoses. by contrast, earlier in the day, this was the far, far larger peaceful mass demonstration, squeezing its way through hong kong's streets. organisers say over a million hong kong citizensjoined in. the authorities say it was a quarter of that figure. well, people are afraid. people are also angry about this extradition treaty. mainland china use all sorts of ways to exercise so—called dictatorship in hong kong, to kidnap the people they treat as enemy.

say no to the evil bill... hong kong officials have said local courts will still have the final say over whether to grant extradition requests, and that suspects accused of political and religious crimes will not be extradited. but that is not good enough for chris patten, lord patten, britain's last governor in hong kong before the handover in 1997. the proposed new law, he says, is a major breach by china. i think it's the most serious challenge to the autonomy of hong kong and to the rule of law in hong kong since we left in 1997, and it flatly goes against all the promises that were made about guaranteeing hong kong's local autonomy. but the sheer scale of protest may not be enough. although opposition to the bill has united businesspeople, often pro—establishment, with lawyers, students and shopkeepers, it seems unlikely that china is ready to give ground. james robbins, bbc news.

at least three people are reported to have been killed in clashes with security forces in sudan during the first day of a campaign of civil disobedience. tear gas and live ammunition was fired at people trying to set up barricades. opposition leaders called the strike in response to the killing of dozens of protestors by government—backed militias last week. from khartoum, here's our africa editor fergal keane. the city is lifeless, but the revolution still breathes. we went to the neighbourhood of bahari, where silence and absence have replaced the joyous crowds. but they make no less powerful a point. this street should have been full of workday crowds. we met only groups of youths trying to defend the area from the regime's militia.

translation: there is fighting here. there are big problems here in sudan. there is no justice, and people want justice. we want our rights. it feels like a state of siege, people protecting themselves from their own government. the military regime has tried to break the back of these protests with killings, with torture, with mass arrests. but still, here on the ground in khartoum, the people are defying them. for a week, these men have terrorised the city — the militia known as the rapid support forces. but locals them by another name, the janjaweed, notorious for killing and rape in darfur. as we travelled across the neighbourhoods, people cleared barricades to let us pass. they're desperate for the world to know what the militia is doing. this prominent opposition

figure was only released from jail in april. the great fear right now, that is still there is so many killings, all over. no—one can go outside, outside his home, and feel safe. 37—year—old waleed abdalrhman is pictured here during the euphoric days of the protests. this morning, he was killed by a militia sniper. there was a barricade and he talked to his friend there, said his uncle, ismael. there were police nearby, but they had no reason to shoot him. no reasons for his killing. no, at all. just kill him, and that's it. so much has changed for them in so little time. the son that lived this morning is dead tonight. the country they hoped for is being stolen away. fergal keane, bbc news, khartoum.

earlier, i spoke to aly verjee, a senior advisor at the united states institute for peace, who told us more about the civil disobedience. the general strike which began on sunday was largely successful. but again, it's also worth noting that this is a movement which is beyond khartoum. in omdurman, the largest town, a coastal city in sudan, the port is certainly deserted. and so this is a movement which has been able to persist despite the odds, and mobilise people to remain away from work, and heed the call for disobedience. there might be many reasons inside the country for what is happening, but there are regional interests at play as well, specifically saudi arabia, the united arab emirates, to name two. why are they so interested in what happens in sudan? well, there certainly

are outside interests, and clearly president bashir and the sudanese military is much more closely in the camp of the saudis and the emiratis, and both riyadh and abu dhabi would like to keep it that way. there are, of course, sudanese troops also in yemen. so there are reasons that are direct to sudan. there is also a general broader view on the gulf that stability is important, and democratic reform and transitional government would be more complicated, and better to have a reliable partner, and that's what the sudanese military provides to those countries. do we have any evidence for how these regional interests, these two countries you mentioned, might be influencing events in sudan as they unfold 7 well, certainly both countries have contributed financially to the transitional military council, giving them space, in terms of financial

manoeuvrability, but also backing to repress protesters, as it has. that is the most visible evidence. in the last few days, there's been pressure from the us on both riyadh and abu dhabi to make statements and to pressure khartoum to show restraint, and both countries have issued statements. but i think these are really half—hearted efforts, and clearly, as the killings continue in khartoum and elsewhere, have not been heeded by the authorities in sudan. let's get some of the day's other news. tensions between turkey and the united states are rising over ankara's decision to buy russian anti—aircraft missile systems. washington has given its nato ally a deadline to choose between buying russia's s—400 systems or us—made f—35 advanced fighter jets. it argues the russian systems are both incompatible with nato defence systems and pose a security threat. the us wants turkey to buy its patriot anti—aircraft systems instead.

protesters took to the streets in the capital of haiti demanding presidentjovenel moise resign over allegations he embezzled venezuelan aid money. buildings and barricades were set on fire in the demonstrations, spurred by opposition parties and civil society groups. at least one person is reported killed in the unrest. authorities in kazakhstan say they've arrested about 500 people demonstrating against what they said was a fixed presidential election. interim president kassym—jomart tokayev, the hand—picked successor to the long—time authoritarian leader nursultan nazarbayev, is expected to win. exit polls indicate that he has around 70% of the vote. the bbc‘s rayhan demytrie is following developments for us from the capital, nur—sultan. riot police is moving in to push these protesters. many have already been arrested and moved to police vans. they're creating this noise to scare people but nevertheless, they're still standing because people are saying they're fed up.

for 30 years, they've never seen democratic elections in this country and this time they're saying they will no longer be quiet about the real situation in their country. translation: they spend billions on building palaces but have no money for mothers with many children. there are just a handful of protesters left here in nur—sultan. they are being detained, mishandled by the police and pushed through many numerous of those buses. so far we witnessed dozens of people being detained and the police just warned them through loudspeakers that unsanctioned protests are not allowed. so after this announcement, they're now going and detaining people one by one. but people are saying here that to get permission for peaceful protest is almost impossible in kazakhstan and that they're simply exercising their right

to peaceful assembly. stay with us on bbc news, still to come: a new way to see london — the annual balloon regatta takes to the skies over the capital. the day the british liberated the falklands. and by tonight, british troops had begun the task of disarming the enemy. in the heart of the german capital, this was gorby—mania at its height. the crowd packed to see the man who for them, has raised great hopes for an end to the division of europe.

michaeljackson was not guilty on all charges. the screams of the crowd, a testament to his popularity and their faith in his innocence. as long as they'll pay to go and see me, i'll get out there and kick 'em down the hill. what's it feel like to be the first man to go across the channel by your own power? it's feels pretty neat. feel marvellous, really. this is bbc world news. our main headline: clashes between protestors and police in hong kong marked the end of what organisers say was a million—strong march against the territory's proposed new extradition law. the chief executive of hong kong is speaking. this is herfirst responses since the protests we saw.

organisers are saying a million people took to the street so the concerns about that extradition law, that new law that will allow suspects to be extradited to beijing in china, many people are concerned about it. hong kong says there are enough provisions in place to protect people but many people are still concerned inside hong kong. we will keep across events as that continues. let's get more on that story. alkira reinfrank is a journalist with the south china morning post who observed the march. she has been describing what she saw. it was a historic scene yesterday, i've never seen so many people. it's the middle of summer here so it's about 32 degrees and 90% humidity, yet it didn't deter protesters. i was stuck in an area about two football fields for a good two hours before we even started moving

because there were just so many people that came out to protest this controversial extradition bill to china. and hong kongers have a history of protesting but this was on a whole new level. organisers are saying over a million people turned up for the protest, but police are saying only 240,000 people there, at its peak. now, hong kong police are notorious for underplaying how big crowds are. i've never seen a million people, but i was in the crowds for about 8—10 hours yesterday, and the protesters just kept coming. it was a sea of white snaking its way through the streets of hong kong, and there was a real sense of unity. it must have been incredible to be amongst so many people. how will china respond to this, do you think, if they will at all? they must be a little bit worried.

well, i have no doubt that china would have had eyes on this, but on weibo, one of the main social medias in china today, you type in hong kong and there's — you can't find anything of it now. basically, this week, it will be decided what happens with the extradition bill. that's why the protests took place on sunday. but there's been two amendments that have already taken place to the bill, so i spoke to a number of people in the crowd yesterday, and there was a sense that perhaps this protest might not have an effect of what takes place this week, but it didn't stop people from fighting for their rights, fighting for their rights for freedom of speech, and that was quite amazing to see and to be a part of. there was younger generations up to extremely — there was elderly that were getting through the sweltering heat, as well. and there was a sense of quiet determination.

i feel like, if this protest of this magnitude had taken place, say, in the uk or in australia, the heat, the close confines of everyone being stuck in one area before police opened more streets — i think there would have been a riot. but it was, for eight hours, very peaceful, and people were wearing white. and there was a real sense — a few hours before the protest took place, i was in one of the mtr train stations, and it was completely blocked. there was just a real sense — everyone was messaging and saying this is going to be huge. it felt like almost everyone in hong kong was there. but if the organisers are correct, if a million people did show up, that's one in seven people in hong kong were at this protest. here in the uk, nominations open on monday in the contest to become the new leader of the conservative party and the next british prime minister.

questions about past drug use have continued to dog one of the candidates. the environment secretary, michael gove, has admitted he was fortunate not to be jailed for using cocaine 20 years ago. one of his rivals, the home secretary, sajid javid, said those who take drugs destroy countless lives. our political correspondent chris mason reports. imagine you are a candidate to be our prime minister next month. you wake up to front pages all about you saying things like this, and your next appointment, having admitted taking cocaine on several occasions two decades ago, is a tv studio. what a weekend for a man who used to be justice secretary. yes, it was a crime, it was a mistake. i deeply regret it. should you have gone to prison? well, i was fortunate in that i didn't, but i do think that it was a profound mistake, and i've seen the damage that drugs do. mr gove had hoped to talk up his policy plans, like replacing vat with a simpler sales tax. instead, he had to fend off

questions about whether he had been honest about his drug—taking, including when he applied for a visa to go to america. i don't believe that i've ever, on any occasion, failed to tell the truth about this when asked directly. and one of the things... but it would be on the form. you would have to say yes or no, and if you had said yes, you could be banned for life from entering the united states. i think it is the case that, if i were elected the prime minister of this country, then of course it would be the case that i would be able to go to the united states. and i think that it's foolish to suggest otherwise. enter next, in another studio, the home secretary, whojust so happens to be a leadership contender too. who could possibly on his mind when he makes this general observation about some drug takers? they have their organic food, they boast about buying fair trade, they talk about climate change. and at the same time, you know, come friday or saturday night, they're all doing class a drugs.

and they should be thinking about the impact they're having, especially on children. and then there is brexit. the frontrunner, boris johnson, gave his first interview of the campaign today, saying he would hold onto the divorce payments the uk has said it will pay the eu until a deal on their future partnership is done. watch out — watch out, guys. he also wants to scrap the backstop, the insurance policy to keep the border on the island of ireland open in all circumstances. his critics point out brussels has repeatedly said no. there are currently 11 candidates to replace theresa may, among them this man, the foreign secretary, jeremy hunt, who voted remain in 2016. the question now is not how you voted in a referendum three years ago. it is who has the skills to deliver a deal that is going to get us out of the eu before we have a general election, and i have those skills. so here goes — the noise, the flashbulbs, the focus on those

who want to be prime minister. south korea has some of the worst air quality in the developed world, according to international figures. in densely populated cities like seoul, it is very common for people to wear masks to protect themselves from the pollution. but now, dog owners are becoming concerned about the health of their pets.

just interrupting that story to take you live to hong kong, where carrie lam, the chief executive, is speaking. i think they clearly demonstrate that these rights and freedoms are as robust as ever. of course, we were very sad to watch on tv after midnight that there was some violence undertaken by a few hundred protesters, including attacking the police, obstructing the roads, et cetera. as a result, several police colleagues and at least one reporter and maybe some other people have been hurt. i want to extend to them my warmest sympathy, and hope that they will

recover as soon as possible. the police, as mentioned by the commissioner of police earlier this morning, we are taking very serious actions against those breaches of the law, because hong kong is a very lawful society. while we respect and uphold the freedoms of expression, we also expect every citizen to obey the law. now, coming back to the substance of the margin the protest, i understand, i fully substance of the margin the protest, i understand, ifully understand, that during the march, many of the participants have expressed worries and concerns and anxiety about the government's attempt to amend the legislation. i have also heard from the political parties who have issued statements after the march, while reaffirming their support for

the government's action, they also have put forward some constructive suggestions. so i am responding in the following four areas of work. one is we realise that our communication and explanation work has to continue. whether throughout the legislative council's process, or even after the enactment of the bill, because this is a very important piece of legislation that will help to uphold justice, and also ensure that hong kong will fulfil her international obligation in terms of cross boundary and transnational crimes. the explanation, i hope, will focus on the additional safeguards that we have introduced, especially on 30 may, by the secretary of security. those six measures will provide some of the very reassuring human rights safeguards that we have heard some people, especially from the legal sector, will have put those

proposals to us in the earlier part of the consultation. our experience is, as long as there is a chance for us is, as long as there is a chance for us to interact and to explain and a nswer us to interact and to explain and answer questions directly, face—to—face, normally it will have a very positive effect on the other stakeholders, to improve or enhance their understanding of what we are doing. the second area of work that we will do is, coming back to the additional human rights safeguards that we have announced on 30 may, i heard that there was some worry that all of this was just sort of state m e nts all of this was just sort of statements made by a government official, and they are not particularly reassuring. so i'm telling you hear that, in this area of work, we will make sure that all these additional safeguards, and there's a long list of those

additional safeguards, which resemble very closely the international standards and the icc pr minimum guarantees, they will have legal binding effect on the government. because we will put them into a very solemn policy statement to be delivered by the secretary for security when the bill resumes its second reading in the legislative council. and if one cares to go into the bill itself, there is a very specific provision that says that, as long as we ask these safeguards from the requesting party and put them into some sort of agreement, then they will of course sort of restrict or confine the executive's ability in the surrender of offenders. so in short, these human rights safeguards have binding effect, and we will only surrender a fugitive requested by a requesting party when these guarantees are being fully met. the third area of work is in response to a suggestion from some political parties late

last night that if the bill were passed, both political parties suggested that the government should provide regular reports to the legislative council about the implementation of this sort of case—by—case surrender arrangement, in terms of the jurisdictions involved, the nature of the cases, and whether the human rights safeguards and procedural safeguards that we have been talking about are being fully implemented. finally, i have two stress again that we said at the very beginning of this exercise that this special surrender arrangement, that is a case based surrender arrangement, arrangement, that is a case based surrenderarrangement, is arrangement, that is a case based surrender arrangement, is a supplementary arrangement, is a sort of stopgap arrangement. because we do have a very serious gap and efficiency in ourjustice system. but the long—term arrangement or the long—term goal is still to enter

into long—term agreement on the surrender ofjudicial offenders with as manyjurisdictions as possible. we now have 20 such agreements. we should increase these bilateral agreements as far as possible, so i will put a priority on this area of work, and will immediately enhance staff resources in the security bureau and the department ofjustice to enable them catch up on the work and to start the negotiations on this long—term agreement, including negotiations with the mainland of china, taiwan and macau. finally, i wa nt to china, taiwan and macau. finally, i want to say to every citizen in hong kong who has expressed the view on these amendments, whether you are agreeing or not agreeing with us, whether you are supporting the work we are doing or objecting to the work we're doing, i want thank eve ryo ne work we're doing, i want thank everyone of you. because the concern of every citizen about the work that

the government is doing, and this scrutiny of our work, is an important factor to enhancing good governance in hong kong. thank you very much. that is carrie lam, speaking. she is the chief executive of hong kong. she is obviously responding after those huge protests that were seen in hong kong over the weekend. those protests against the extradition laws, the new proposed extradition laws, the new proposed extradition laws, the new proposed extradition laws, to send suspects to china. now, she has addressed eve ryo ne to china. now, she has addressed everyone in cantonese, then she addressed everyone in english, and she talked about some of the violence that was seen after the protest. and she was concerned about that. she did say that action would be taken, then she went through several points about what her government wants to do in order to respond to
