hello and welcome to bbc news. the british foreign secretaryjeremy hunt says britain will do what it takes to keep international shipping safe after a uk registered oil tanker was seized by iran in the gulf. mr hunt said tehran had assured him last week that it wanted to de—escalate tensions in the region, but was now doing the opposite. iran has released footage of the moment its troops seized the vessel. our diplomatic correspondent, paul adams, has more. this is the moment iranian revolutionary guards took over the stena impero, descending from a helicopter onto the deck of the tanker, as fast boats circled nearby. iran says the ship had broken international regulations following an accident involving a fishing boat. the ship's owners have not confirmed this and say it was obeying the law. it's now being held at the iranian port of bandar abbas. we are calling on iran

to reverse this illegal act. we're looking for ways to de—escalate the situation, but we're also very clear that we will do what it takes to ensure the safety and security of british and international shipping. the tanker was making its way through the busy strait of hormuz, in omani waters, when it was intercepted. it made a sharp turn north towards iran, a clear sign that something was wrong. a british warship, hms montrose, was alerted and raced to intervene, as it did successfully with another british—flagged tankerjust over a week ago. but this time, it was too far away. the tanker was already in iranian waters. to allow a ship to go out when we knew the iranians wanted to actually take a hostage is extraordinary, and it's hardly surprising. they said they would do it. several times they said they would do it and, lo and behold, they've done it, and now we've got in this very difficult situation. tensions started to rise last year, when donald trump pulled the us out

of a 2015 nuclear deal with iran and imposed crippling sanctions. iran grew increasingly frustrated. in may and june, it was blamed for a series of attacks on international tankers. then, in a dramatic escalation, iran shot down an american surveillance drone. donald trump briefly contemplated a military response. and earlier this month, off gibraltar, the royal marines intercepted a tanker full of iranian oil that britain said was bound for syria. iran threatened to retaliate. today, iran's foreign minister accused britain of piracy. "it is iran", he tweeted, "that guarantees "the security of the gulf and the strait of hormuz. "the uk must cease being an accessory to the economic terrorism of the united states." what we have at the moment are two captured tankers and an angry war of words. mr hunt says he feels betrayed by his iranian opposite number. he says that javad zarif told him a week ago that iran wanted to de—escalate the situation,

but that iran had done the opposite. the stena impero and its multinational crew, which does not include any britons, are now prisoners of iran's revolutionary guard, hostages in a deepening geopolitical row. paul adams, bbc news. india says it's in touch with tehran to secure the release of 18 of its nationals who are part of the crew of the stena impero tanker seized by iran. our middle east correspondent tom bateman is in the port of fujairah on the strait of hormuz — he gave us this update about the crew. in these waters just here that the ste na in these waters just here that the stena impero was living as anchorage, was due to make what should have been a routine voyage was to a port in saudi arabia, instead tonight the crew of 23 people find themselves off the coast of iran may, out of contact with theirfamilies of iran may, out of contact with their families and with the uk—based firm managing the technical elements

of the ship. in terms of the owners, they have been speaking to them throughout the course of the last 2a hours or so. they have spoken of their anxiety for those crew. they are mostly indian, but there are also russians, a latvian, and a filipino on board the vessel. one official from the company told me they have heard in the last few hours, via their insurers, a board official in iran that the crew is and what they describe as good health, albeit the company itself has had no direct contact with the crew and they do not know what will happen next to the vessel. but these are tense times for tankers in the strait of hormuz. it feels like the anti—is being upped even further. in particular due to the fact that british vessels are now being advised to stay away. tom bateman there. british airways has suspended all flights to cairo for seven days. in a statement, ba says

it was taking the measure as a precaution to allow for an assessment of security there — but doesn't give any further reasons. the german carrier lufthansa has become the second airline to cancel flights to the egyptian capital over security concerns. flights are due to resume on sunday though. the bbc‘s matt cole reports. for some cairo—bound passengers, the first sign of trouble was when their boarding passes failed at check—in. others have told of confusion from ba ground staff as news filtered through that all the airline's flights to and from egypt's capital were being suspended. at one stage, the met police were called to deal with agitated would—be travellers. it is very disappointing and frustrating, especially to my kids and family. we have a big family over there waiting to see the children. there was no information, there was no help, there was no advice on any alternative ways of getting there. it was just a case of, "ring this number", which of course you couldn't get through to. ba says it made the decision

to suspend flights, but has given few details as to why, save for a short statement which said... "we constantly review our security arrangements at all our airports "around the world and have suspended flights to cairo for seven days "as a precaution to allow for further assessment." the uk government says it is aware of ba's flight suspension but, other than acknowledging that, the foreign office has made no alteration to its long—standing advice for travel to egypt. we understand that ba has helped some passengers to complete their journey, flying via other countries on ever airlines into cairo. it seems to suggest that ba is happy for people to land at the capital ‘s airport, just not on its airport. ba does address the safety of its passenger and crew ‘s priority. mark

cole, bbc news, and heathrow airport. with me is our news reporter ramzan karmali. how unusual is this kind of move beau bridges your ways? it is very unusual. just a short period of time, seven days. we have heard about passengers turning up to the boarding gates with a boarding pass and the pass not working. that is very unusual stop ba takes passengers to cairo on a daily basis. in total, around 400,000 people travel to egypt as a whole. in fact, more, people travel to egypt as a whole. infact, more, british people travel to egypt as a whole. in fact, more, british travellers tend to go to the tourist resort, not cairo. flies are still going on with other airlines. it is important to suggest this is a ba issue only. the foreign office is set only to travel if it is essential. that has been there for some time. they have said there is a heightened risk of terrorism against aviation, but they don't mention what that risk is or who that risk is two. this is a decision made specifically by ba. in

fa ct, decision made specifically by ba. in fact, it makes us want to ask more questions rather than give any a nswe rs. questions rather than give any answers. they have really not been forthcoming information. exactly. what about other airlines? lufthansa has stopped flies on saturday but are resuming on sunday. exactly. it seems unusual that they would resume flights the next day. thomas cook, the biggest carrierfor flights the next day. thomas cook, the biggest carrier for uk flights the next day. thomas cook, the biggest carrierfor uk nationals to egypt, they mainly go to the red sea resort of hrgota. they are carrying on as normal. manchester is the big cup into either. they are carrying on as normal. easyjet have said they will continue to fly as planned, but they will keep the situation under continuous review. they are obviously keeping an eye on this but are carrying on with their flies. as you say, more questions than answers at the moment. thank you very much for the update. let's get some of the day's other news. more than 20,000 people have taken to the streets of the russian

capital moscow to protest against the exclusion of opposition candidates from registering for local elections. officials barred around 30 candidates from running, claiming they failed to qualify. those excluded say they're being punished for challenging the control of putin loyalists. in london, pro—european opponents of brexit have held a "no to boris, yes to europe" march. it featured this inflatable cartoon of boris johnson, the man expected to become the next british prime minister. he — or his only rival, jeremy hunt — will take over in number 10 downing street next week. both have promised to see brexit through, but only mrjohnson had his own balloon caricature. the triumphant algerian men's football team have received a hero's welcome on the streets of algiers after their victory in the african cup of nations. algeria beat senegal one goal to zero during last night's final in cairo, taking home the trophy for the second time in its history. forensic experts have extracted bones from a burial chamber at the vatican in an attempt to solve the disappearance of a 15—year—old girl in 1983. emanuela orlandi's family received an anonymous tip—off earlier this

month that she might be buried in the tomb. rhodri davies has more. 36 years missing and still they are searching. these experts are looking through two chambers at the vatican in the case of emanuela orlandi. it follows the opening of two terms in a vatican cemetery after orlandi's family lawyer received an anonymous tipoff pointing to the marble topped graves. the tombs turned out to be empty and the chambers revealed only centuries old bones of two german princesses. orlandi's family had urged the vatican to open an internal investigation into the disappearance, which it did this year. she was the 15—year—old daughter of a vatican employee. she vanished in rome in 1983 after her flute lesson. it is a disappearance

that has kept italians captivated. it is probably italy's most enduring mystery. everybody has a theory about it, a favourite theory. she is inside the vatican, some say. it could be the islamic terrorists who wa nted could be the islamic terrorists who wanted the release ofjohn paul ii's would—be assassin. is almost no enormous sympathy for the family and support for the investigation. at the family has regularly appealed to the family has regularly appealed to the vatican to provide more information and some people say the holy see knows more it is telling. orlandi's father died still wanting chances. her brother has now made resolving the case his life's work. but with the latest attempts lacking a breakthrough he'll continue to search for her. rhodri davies, bbc news, stay with us on bbc news, still to come: 50 years ago almost to the minute — the world held its breath as the eagle module touched down on the moon's surface

mission control: you can see them coming down the ladder now. it's one small step for man, one giant leap for mankind. a catastrophic engine fire is being blamed tonight for the first crash in the 30 year history of concorde, the world's only supersonic airliner. it was one of the most vivid symbols of the violence and hatred that tore apart the state of yugoslavia. but now, a decade later, it's been painstakingly rebuilt and opens again today. there's been a 50% decrease in sperm quantity and an increase in malfunction of sperm unable to swim properly. thousands of households across the country are suspiciously quiet this lunchtime as children bury their noses in the final instalment of harry potter.

this is bbc news, the latest headlines: footage from iran shows the seizure of a tanker in the gulf. london says it's working to defuse the crisis. british airways and lufthansa have suspended all flights to and from cairo over security concerns. 50 years ago today, neil armstrong took that first, small step onto the moon's surface — a pioneering moment watched by an estimated 600 million people back on earth. while originally fuelled by cold war rivalry, it's become a source of inspiration across the globe, with events taking place worldwide to mark the anniversary. our science correspondent pallab ghosh reports ‘s and liftoff. 50 years after a small step for man... three astronauts heading

to the international space station, 250 miles up, a far cry from the moon, more than 1,000 times further away. today, the american vice—president promised that the glory days would be back. america will return to the moon within the next five years, and the next man and the first woman on the moon will be american astronauts. the vice—president also paid tribute to these three men, who set off to the moon 50 years ago. three, two, one... we have liftoff. neil armstrong reporting the roll and pitch programme which puts apollo 11 on a proper heading. four days later, neil armstrong, buzz aldrin and mike collins arrive at the moon. as the lunar lander descends,

neil armstrong notices that they're off—course. instead of the preplanned smooth landing site, there are dangerous boulders. with fuel running low, commander armstrong takes manual control. the eagle has landed. roger, tranquility. armstrong then descends onto the lunar surface. it's one small step for man... one giant leap for mankind. on tv all across the world, 600 million people were watching. it has a stark beauty all its own. it's like much of the high desert of the united states. it's different, but it's very pretty out here. at the time, all things seemed possible. yet three years later, the apollo programme ended and humans haven't been back since. it was america's flag planted, but this moment was an achievement for all humanity. pallab ghosh, bbc news.

earlier, i spoke tojonathan mcdowell of the harvard—smithsonian centre for astrophysics about the lasting legacy of that extraordinary moment. scientifically it was a bonanza for understanding the early history of the solar system including the history of our own earth because the moon preserves the events that happened billions of years ago that the geology and atmosphere on earth have wiped clean. and, so, we learnt a lot about how the role of asteroid smashing into one another and how the earth and other planets came to be. so scientifically there is still paper being published from apollo data. and at the time, culturally, the idea of a human being on another world, the beginning of, if you

like, a settlement of outer space, ofa like, a settlement of outer space, of a star trek future in which we live on all kinds of worlds, if that comes true hundreds of years from now, people will look back on my generation as the ones who saw that and experienced that first step into other worlds. that for me is the legacy. buzz aldrin expressed his disappointment in how the space programme panned out the last few decades. what is your view? is the future of space lived up to the expectations, hopes and dreams that was sparked by that first landing? in some ways it has but space is ubiquitous in our lives now. with gps, if that stops working then people won't be able to get to work tomorrow. and communications,

television, all the stuff that relies on the infrastructure we have in place. scientifically we have the hubble and probes the go past pluto and rovers on mars. incredibly advanced staff. what hasn't happened is the human exploration of other worlds. we have devoted part of our website to the moon landing. just log on to bbc.com/news — or download the bbc app — and you can read about and watch the most famous space mission in history. police in hong kong say they have found explosives and other weapons in a raid on a warehouse. they displayed two kilos of explosives, ten petrol—bombs, and literature opposing the plans to allow extradition to mainland china. a senior bomb disposal officer said it was the largest seizure of the explosive tri—acetone tri—peroxide, or tatp, police had come across in hong kong. this is an extremely sensitive and extremely powerful explosive. it

will cause exceptional amounts of damage when used. it is also very u nsta ble damage when used. it is also very unstable and it will react to hate, friction and impact. it puts at risk everybody within this building, it puts at risk bystanders outside. staying in hong kong, and tens of thousands of people have joined a protest in support of the territory's police force, and calling for an end to violence. it comes after a wave of demonstrations against that planned extradition bill. another big anti—extradition protest is planned for sunday. our correspondent stephen mcdonnell has the latest. today, the same day as we have seen this pro—beijing rally, in hong kong it has been the term of the pro ageing camp to rally. they have turned out to support the hong kong government and the city ‘s right police who have been criticised for their at times heavy—handed suppression of the mass

rallies in support of democracy and opposing a controversial bill to allow extradition to mainland chinese courts. while this gathering is not as big as those in the pro—democracy camp, nevertheless there are thousands of people here. however, as you can see, many are already leaving afterjust 30 minutes. one of the reasons for this could be that the weather is driving them back. it is raining and we have heard at times funder. it will be interpreted, i am sure, by the pro—democracy camp is a sign of the lack of conviction of those who are here. they would also say there are many in attendance who are actually from the chinese mainland, living in hong kong, and they are traditionally the supporters of the central government.

brazil's president, jair bolsonaro has launched a stinging attack on his own country's national space institute, saying it's misrepresenting the scale of deforestation in the amazon. according to new data — deforestation has surged to record highs since mr bolsonaro took office. tiffany wertheimer reports. the amazon is the largest rain forest in the world. the huge trees store carbon dioxide, making it vital in the fight against global warming. preliminary satellite data by brazil's national space research institute found it more than 700 km2 of rain forest was lost in may this year. that's the equivalent of two football pitches every minute. and in the first two weeks ofjuly, 68% more rain forest was destroyed then in the whole ofjuly last year. but despite the science, president bolsonaro doesn't accept of the findings. translation: i'm convinced that the data are lies, and we will call the president

of inpe here to about it. the right—wing leader is known for attacking environmental agencies. his policies favour development over conservation. so rainforests are being cleared at a faster rate to make space for cattle pastures. mr bolsonaro's government is lenient towards environmental crimes like illegal logging, and penalties have dropped under his leadership. the national space and research institute is standing by the data, saying it's 95% accurate. in the same news conference, mr bolsonaro said this. translation: to say that people go hungry here in brazil is a big lie. that some are doing badly and don't eat well, i agree with that, but go hungry? no. according to the united nations, about 5.2 million people suffered from hunger in brazil in 2017. tiffany wertherimer, bbc news. extremely hot weather has started
