this is bbc news. welcome, if you're watching here in the uk or around the globe. i'm reged ahmad. our top stories: despite severe warnings from beijing, hundreds of thousands braved the hong kong rain. the protesters show no signs of backing down. an iranian oil tanker, held on suspicion of transporting oil to syria, has left gibraltar. its destination is unknown. burials take place in kabul for the victims of a suicide bombing that killed 63 people. the islamic state group says it carried out the attack. desperate migrants try to swim ashore after the italian government refuses to let their ship dock. and, iceland bids farewell

to its first glacier lost to climate change — with a warning ‘there's no time to lose'. hong kong is gearing up for more protests this week, after hundreds of thousands of anti—government demonstrators braved heavy rain to rally peacefully on sunday, marking a change to what have often been violent clashes. organisers estimate 1.7 million people turned out. the protests began 11 weeks ago, against what some see as attempts by beijing to undermine the territory's autonomy. our china correspondent, john sudworth, was there. his report contains some flashing images. beneath an ocean of colour, hong kong raised its voice again. chanting.

everywhere you looked, there were umbrellas, held aloft in a massive display of defiance. why are you marching today? for hong kong! for hong kong, of course. yeah, freedom. yes. it's a far cry from this, the violent scenes at hong kong's airport earlier this week, which some thought risked undermining public support. the turnout today was seen as a vital test. given the monsoon conditions, this sea of umbrellas will be seen as confirmation that the pro—democracy movement is far from losing momentum. warnings from china also appear to be having little effect. shortly before the rally, the authorities released new footage of troops rehearsing crowd control techniques just across the border. in much of this city, away from the protests in working—class neighbourhoods like this one, there's the appearance of normality.

but opinion is deeply divided. "of course it's not good," this woman tells me, "hong kong is a mess." this man says he supports the protests, but he has a pessimistic view about the likelihood of success. "it's in xijinping's hands," he tells me. "the communist party is so strong. it's up to them." this is a spontaneous movement, a mass acting as one, with no real leaders. on the one hand, sheer weight of numbers. on the other, and uncompromising government and no end in sight.

the iranian oil tanker that was seized by gibraltar last month has left port and is heading east into the mediterranean. its destination isn't known, but gibraltar says it has secured assurances from tehran that the cargo will not go to syria. john mcmanus reports. at anchor off the coast of gibraltar, prior to restarting herjourney which was interrupted last month, the grace i has now been renamed adrian darya i and is flying the iranian flag. the authorities in gibraltar said on thursday that the tanker could leave after receiving written assurances from tehran that its cargo of oil would not end up in syrian hands. but its seizure sparked a diplomatic crisis. onjuly 4, british royal marines detained the grace i tanker off the coast of gibraltar on suspicion it was transporting iranian oil to syria in defiance of eu sanctions. iran accused the uk of piracy. in response, the uk deployed an additional warship to the strait of hormuz to protect shipping, but on july 19, iranian revolutionary guards boarded the british—flagged stena impero, detaining it and the 23 crew.

tehran said it had violated maritime rules. its owners said it was in international waters when it was boarded. iran released pictures of that operation and later of the detained crew. one month on, concerns remain for their welfare. there's been no substantial evidence brought forward by the iranians as to why that crew has been detained. our hope is that now grace i has been released that actually the crew of stena impero will be able to now sail themselves or be repatriated. meanwhile, a second attempt by the united states to detain the adrian darya i has failed. gibraltar said it could not comply with washington's request because us sanctions against iran do not apply in the eu. they haven't taken our ships, they've taken ships, but they haven't taken our ships and they better not,

but i will say this, i really think that iran wants to get there. donald trump says iran would like to talk about the tankers but it seems there already may be a resolution to this crisis on the horizon. john mcmanus, bbc news. the islamic state group says it carried out a suicide bombing at a wedding reception in the afghan capital, kabul. 63 people were killed and close to 200 more were injured in saturday's attack in a shia area of the city. auliya atrafi has more. a tragic end to a family celebration. crying and yelling. wedding guests are burying the dead. here, 13 friends and families buried in one mass grave.

translation: in this attack, i myself lost two family members, my brother and my nephews. you could never imagine that such an incident could happen ata wedding. the feast was abandoned, as people ran for safety. the bombs went offjust as the marriage ceremony was ending. the couple survived, but mirwais, the groom, said he and his wife felt guilty that so many people had died at their wedding. translation: i have lost hope. i've lost my brother and my friends who came to join my wedding party. the celebration of independence day doesn't matter to me any more. more than 180 guests were injured. many are here, fighting for their lives. the family are not known to be political, and the fear now is that the attackers have switched from targeting politicians and officials to targeting

ordinary afghans. hours after the attack, families are still looking for their loved ones here at the emergency hospital. this attack was particularly shocking, because normally when civilians are caught in conflict, it's a matter of being in the wrong place at the wrong time, but here a wedding was specifically targeted. people aren't feeling safe anywhere any longer in this country. those safety concerns are increasing, especially now that the islamic state group has claimed it carried out the attack. taliban assurances that they are in control throughout the country are no longer credible. aulyia atrafi, bbc, kabul. let's get some of the day's other news. president trump says he's unlikely to grant another temporary reprieve to the chinese technology company huawei, citing national security concerns. in may, his administration banned huawei from doing business with us

companies, but the commerce department subsequently gave the company a ninety day reprieve. parts of northern india have been hit by severe weather. flash—floods have left at least 22 people dead in the state of himachal pradesh. roads have been swept away in some areas, and two national highways have been blocked due to landslides. argentina's economy minister, nicolas dujovne has resigned after a week of financial turbulence in the country. his departure follows the government's defeat in primary presidential elections. the argentinian peso lost 20% of its value against the us dollar after president macri suffered electoral losses last week. canada has accused the uk of "offloading its responsibilities," after a british man with dual nationality, who'd travelled to syria to join the islamic state group, was stripped of his uk citizenship.

jack letts was captured by kurdish forces two years ago. he's currently being held in prison in northern syria. our security correspondent frank gardner has been speaking about the canadian reaction. apologies, we don't seem to have that from frank gardner but we do have audrey macklin. audrey macklin is a law professor at the university of toronto and specialises in citizenship and migration. she gave me her reaction to the uk's decision. think about this question. if jack letts is a threat to the national security of britain because of his involvement with isis as a foreign fighter, in what way is he less of a national security threat to canada? by the same token, by what standard could jack letts, born, raised and formed by england, be properly considered more of a responsibility of canada,

the sole responsibility of canada, rather than the uk? so i think it's fair to say, if your viewers could put themselves in the position of canada, they might well wonder about both the ethics and the legality of the uk act. some who perhaps support the uk's decision might argue that they view citizenship as a privilege as opposed to a right and that canada doesn't have to repatriate jack letts, and in fact, canada has said that it doesn't have an obligation to return any of their citizens. ultimately, a state has a legal obligation to admit its nationals, sooner or later it does. and this idea about citizenship being a privilege rather than a right, well, if it's a privilege for the uk, it suddenly becomes a right with respect to canada because no country can legally make a citizen stateless. so if the uk think that it's a privilege for uk nationals, it can't also be a privilege for the other state of citizenship. that's the way it works.

there are some who might argue that the uk government has domestic support for this kind of action. what is the view in canada of repatriating citizens who have fought with islamic state? well, i'd invite your viewers to consider how it might look from the other side. if this is such a great policy then i guess the uk would like to see every country in the world emulated. so if canada presently had the same policy as the uk, that is the ability to strip citizens of their nationality if they have another citizenship, i guess really what you'd see is the uk and canada in a race to see who could strip jack letts‘s citizenship first. hard to see how that advances global cooperation in the struggle against terrorism and radicalisation. in fact, it seems like a grubby, parochial move. it obviously is a complicated subject which many countries are grappling with but i'm wondering

what the view is in canada amongst canadian citizens. it's not that popular in canada, either, for repatriating people who have fought with islamic state? of course, it's an issue, it's difficult. nobody is crazy about the challenges that it poses but that doesn't provide a justification for imposing the responsibility on some other state. every state has a responsibility that it owes to its citizens that it can't simply disavowal by, in effect, trying to depose of them on another state, so it's really a collective responsibility that every state has a responsibility to uphold. some of the migrants stranded on board a charity ship off the coast of italy have jumped into the sea to try and swim ashore. they've been marooned for two weeks, after the italian government refused to let them dock. spain has now offered to take the vessel, but the ship's owners say that's too far to travel. here's leigh milner.

crying and screaming. chaos and frustration aboard the migrant rescue boat proactiva open arms. they've been stranded off the coast of the italian island lampedusa for two weeks now, and in the desperate attempt to reach the shore, some have decided to take matters into their own hands. italy's government has reluctantly allowed 27 children and two newborn babies to disembark from the open arms. the rest have been told to stay on board. translation: the two newly-born children i promised to get off, but the presumed minors, the presumed refugees fleeing a presumed war, presumed sick people, no. i am alone against everyone. the prime minister wrote to me to get people off. the court has opened a case. do i need to end up injail because i defended the borders of this country? there are now more than 100 migrants left on board, most of whom are african who were picked up off the coast of libya. following italy's refusal to dock,

spain has since offered to take the boat in, but crews say they won't be able to last for another six days of sailing. translation: we've been warning for days, people jumping into the water, fights, violence, panic, anxiety, crisis. what else do we need, dead people? those who did not die at sea have to die here on board the open arms. is that what we need? i hope the public persecutor office act and act now, this is unsustainable. only a few civilian rescue boats like this one are still operating in the mediterranean. as they say, they face more and more hostility at european ports. leigh milner, bbc news. stay with us on bbc news, still to come: the power station that inspired poetry, but the demolition didn't quite go to plan.

washington, the world's most political city, is today assessing the political health of the world's most powerful man. indeed i did have a relationship with ms lewinsky that was not appropriate. in fact, it was wrong. in south africa, 97 people have been killed today, in one of the worst days of violence between rival black groups. over the past ten days, 500 have died. chanting: czechoslovakia must be free! czechoslovakia must be free! chanting: czechoslovakia must be free! russia is observing a national day of mourning for the 118 submariners who died on board the kursk. we all with them now. with — in our hearts. the pope has celebrated mass before a congregation of more than 2.5 million people in his hometown of krakow. "stay with us, stay with us", chanted this ocean of humanity. "well, well", joked the pope, "so you want me to desert rome?"

this is bbc world news. the latest headlines: hundreds of thousands of people braved heavy rains, for hong kong's latest pro—democracy march — the 11th consecutive weekend. burials have been taking place in the afghan capital, kabul, after a bomb exploded at a wedding killing 63 people. there's a warning that a rise in the spread of hiv among drug users and the homeless in glasgow is the most serious the uk has seen since the 1980s. the bbc has learnt that at least 157 cases have been confirmed in the last four years. our scotland editor sarah smith reports. just one tiny drop of blood can test who has been infected by the rapidly spreading outbreak of hiv in glasgow.

so, as i said, just put this in here, ok, and we wait. aye. so if it's one line, it's — it means there's no hiv antibodies in the blood, and if it's two lines, there is. we'll just set that aside just now. injust minutes, robbie gets the news he'd hoped to hear. i'm pleased to tell you there's one line, which means you don't have hiv. aye. sleeping rough and injecting drugs, he knows he is at high risk of infection, so robbie says he always takes care to get clean needles, available free from various chemists and charities. do you know people that do share needles? aye. i said if you can go out of your way to get your money to get drugs, get drugs, you can do it right, you get the paraphernalia to have the drugs. you know, it's not hard, know what i mean? waverley care in glasgow are the first and only team anywhere in the uk taking hiv testing onto the streets. they gave us an exclusive look at their attempts to reach

the growing homeless population in glasgow. you do see people getting anxious. everybody seems to know someone with hiv, but weren't aware of the outbreak. they don't know the numbers. they may be aware of one or two people in their close circle of friends, but not aware of the potential hundred—plus that is connected to glasgow city centre who are hiv—positive. widespread widespread hiv testing, trying to identify everyone who is infected, could help to contain the outbreak. but at the moment, the really worrying thing is that the spread of the infection in glasgow seems to be rapidly escalating, with around a 100% increase in new cases this year so far. this man is a heroin addict who manages his hiv with prescription medication. when he was first diagnosed, though, he was terrified the infection would be fatal. i tried to overdose. what, you tried deliberately — you tried to take an overdose

because you find that you were hiv—positive? aye. as i was sliding down the wall, somebody touch me on the shoulder. ijumped up. so they saved my life. why is there such a bad outbreak of it in glasgow? see, the people that's got it, i think that they're not telling... i think not telling people that they've got it, and they‘ re letting them use their needles. why do people take the risk? once you start withdrawing, you start getting mad thoughts in your head, and all that, and you want to get rid of them. and i suppose some people would do anything just to get rid of it, you know what i mean? living on the streets with hiv is not easy. not everyone takes their medication every day, not when heroin is a higher priority. that's why halting the spread of infection is so urgent,

and so difficult. sarah smith, bbc news, glasgow. the capture of wild african elephants for zoos is to be banned by the convention on international trade in endangered species. a committee at the cites conference in geneva approved the ban, but it will still need to be passed by the full conference. the decision applies to southern african countries. elephants in western, central and eastern africa are already banned from all trade. a ceremony has been held in iceland to unveil a plaque commemorating the disappearance of a 700—year—old glacier. it's the island's first to melt away due to climate change, but scientists warn it won't be the last, unless immediate action is taken. courtney bembridge reports. photographs taken from space show just how rapidly the 0k glacier disappeared. in 1986, it was a mass of solid

white, spilling from the crater of an extinct volcano. but by 2014, it was no longer thick enough to move, and the glacier officially declared dead by glaciologist oddur sigursson. translation: by reaching this stage, the nature of the glacier changes dramatically. it starts to slide. it erodes the land beneath much more quickly. dirty water emerges from it, and the water stops seeping through it. five years later, iceland's prime minister and environment minister were among the mourners who gathered to commemorate the loss of the glacier. the idea for a memorial came from two professors from a texan university who made a documentary about the loss of the glacier in 2018. one of them is cymene howe. now is the time to act, it's already past the time to act. and so, in some ways, we see this as a memorial to recognise the loss of this glacier, and in that sense it's a sad moment. but we also see it

as a call to action. iceland is home to more than 400 glaciers. ok is the first to lose its glacier status but scientists warn all of the island's glaciers could be lost within 200 years due to climate change. a plaque unveiled at the site titled a letter to the future reads, "this monument is to acknowledge that we know what is happening and what needs to be done. only you know if we did it." courtney bembridge, bbc news. staying with glaciers, take a look at these pictures of kayakers getting right up close to one in alaska. huh. 0h! huge chunks of ice fell off the glacier, causing a massive wave that came straight at them. the kayakers were unhurt

as they very quickly paddled away. now whenever there's a plan to demolish a megastructure, you can be sure of a good crowd — especially if there's dynamite involved. that was certainly the case in the english town of didcot where three famous towers once used to produce electricity were turned to rubble. it didn't quite go as planned, though, as louisa currie reports. they've watched over didcot from more than half a century. boom. but it took just seconds for the power station's three remaining cooling towers to be flattened. applause. it's quite an emotional thing, really, because those towers have been up since before i was born. so they've always been like a landmark here. finding my way home from a long journey. you would always see the towers whenever you come

in from the motorway and it's in a way something saying you're nearly home. i feel quite sad losing them, really, yeah. the skyline's changed now, forever. work to clear the site has been ongoing since it shut in 2013. today's demolition appeared to run smoothly, but moments later an explosion — 119,000 homes lost power forjust over an hour. once the site is clear, it will be redeveloped. there's already plans to build a hotel there, 400 new homes and it's going to be a site for business, leisure and also residential. so it's changing, already going to have use going forward. before that, there's one last demolition planned in the autumn for the largest chimney. louisa currie, bbc news. now, don't forget you can get a lot more on the didcot power stations on oui’ more on the didcot power stations on our website. it's divided a lot of opinion. people hated, some people it inspired poetry. you can find out

more on our website. stay with us here on bbc news, a lot more coming up. see you soon. hello again. well, we've seen plenty of showers around over the course of the weekend, and showers again the name of the game as we look at the forecast for monday, too. clouds like these will be bringing those showers in. we've seen plenty of those recently as well. radar picture shows the most extensive showers across northern and western areas of the uk. could be a few, though, over the next few hours running through the english channel, and perhaps sneaking onto the coastline of southern england as well. but it's across eastern areas of england, parts of the midlands, that we'll have the longest of the clear spells over the next few hours. but, if you are heading out, it's worth taking an umbrella with you today for sure. it's going to be quite a breezy start to the day, but not cold, temperatures 10—13 degrees, something like that. and for monday, well,

we've still got the same area of low pressure firmly in charge that we had with us through the weekend. the only difference is it's moving over towards norway, allowing the winds to switch to a more north—north—westerly direction across northern parts of the country. showers, though, from the word go, really. i think some of the heaviest are likely to move into northern ireland, across scotland and into the north—west of england. much greater chance of seeing downpours in the east, as well. now, for scotland and northern ireland, the winds are coming down from polar regions, whereas across england and wales, they're coming from the mid—atla ntic. so there is a north—south difference in temperatures. just 16 degrees in edinburgh, whereas we should see temperatures into the low 20s still across eastern counties of england. tuesday's weather, we've got a little ridge of high pressure moving in for a time ahead of this warm front that will spread ultimately thicker cloud and outbreaks of rain into western parts. so rain gets going into northern ireland. it will swing into parts of western scotland, western parts of england and wales as the day goes by. we may well see some of the cloud become quite low for some of the hills.

it's probably a better kind of day across those eastern parts of the country. changes again for wednesday — a cold front swings in this time across the north—west part of the country, high pressure, you'll note, building into the south—east of the country, so some real contrasts in the weather for wednesday. wet and windy weather for northern ireland, the rain getting into western scotland. could see a few spots running ahead of that into north—west england and north wales. but by and large eastern parts of the country dry, and it will turn cloudier, with those temperatures coming up a little. highs of 18 degrees in edinburgh on wednesday, up to 23 degrees in london. once we've got wednesday out of the way, the weather should become dry for a few days, and it should get warmer as well. in london, as we head into the weekend, temperatures could reach 27 by saturday.

this is bbc news, the headlines: the organisers of the latest pro—democracy protest in hong kong say at least 1.7 million people took part in a peaceful rally. the demonstrations have now lasted 11 weeks and sometimes led to clashes with police. china has ordered an end to the protests. the iranian oil tanker that was seized by gibraltar last month has left port and is heading east into the mediterranean. its destination is not known. it was originally seized on suspicion of transporting oil to syria in violation of eu sanctions — something tehran denies. burials have been taking place in the afghan capital, kabul for the victims of a suicide bombing at a wedding which killed 63 people. the islamic state group has said it was behind the attack. coming up at 5:00, ben bland with the briefing.
