this is bbc news. welcome if you're watching here in the uk or around the globe. i'm reged ahmad. our top stories: we will have a celebration of the exact moment 50 years on since it neil armstrong step onto the moon. it has been marked in spectacular fashion. we are here at the national airand space fashion. we are here at the national air and space museum where hundreds gathered to be together for the moment. footage from iran shows the seizure of a tanker in the gulf — as london says it wants to defuse the crisis through diplomacy. british airways suddenly suspends all flights to and from cairo for a week

over security concerns. in hello and welcome to bbc news. a few minutes ago marked the exact moment neil armstrong set foot on the moon fifty years ago. the occasion was marked by washington's air and space museum. the bbc‘s nada tawfik is at washington's air and space museum. she saw it all happened. remind us what happened. just like 50 years ago the apollo 11 mission united americans. hundreds gathered here to mark that moment when neil armstrong made history, becoming the first man on the moon. they celebrated with a giant astronaut made of balloons that they lowered down from the ceiling and it was just impressive to see how many people had that same

wonder and or on their faces, wanting to relive that moment and share it with other americans here, snapping the video on their phone. this has been the culmination of a week of events leading up to this moment where we see reunions from those who fly direct orders and mission control who help along with the two surviving astronauts who spoke about 50 years later how the mission shape the culture in america and shaped their lives. again, just so and shaped their lives. again, just so muchjoy over all of and shaped their lives. again, just so much joy over all of this. a reminder of the apollo era, a time when everything seemed so possible, when everything seemed so possible, when it was unthinkable to have a man on the moon yet it was achieved, it changed perceptions of what mankind was capable of. it was a difficult mission as well and at one point nasser thought it was not going to happen. that is right. when they got the directive from presidentjohn f. kennedy that by

the end of the decade man would be on the moon, it was a scramble. they did not have the technology and they had to hire people. most of the fly directors were under 30 years old in mission control. but they had a can—do attitude and even until the final moments when neil armstrong descended, the eagle landed and the module was on the surface, he had to go with computer alarms off, they we re go with computer alarms off, they were running low on fuel, all of theseissues were running low on fuel, all of these issues were quite dramatic. it worked out, as we know, and uttering the favour —— famous words, the eagle has landed. finally down that letter, placing his left foot on the lunar surface saying one small step for man, one giant leap for mankind. at the airand for man, one giant leap for mankind. at the air and space museum as they

celebrate that moment 50 years ago when neil armstrong was the first man to walk on the moon. thank you very much. nato has condemned iran for seizing a british—flagged ship on friday, describing it as a clear challenge to international freedom of navigation. in a statement, the organisation says it supports british efforts to resolve the issue through dialogue. in another development, the uk has written to the un security council stating its tanker was in 0mani territorial waters, exercising the lawful right of transit and that iran's actions constitute "illegal interference." iran has released footage of the moment its troops seized the vessel. 0ur 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 ships 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 0mani 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, 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. abbas milani, director of iranian studies at stanford university says the release of the seizure video wasn't necessarily aimed at an international audience. i think part of the reason was for domestic reasons. this was very much a theatrical performance, showing iran iranian commandos can take over and an armed vessel.

but there are very real consequences to what everyone has done. how do you think the uk can get out of this without getting into an armed conflict? i think the way the uk has managed so far as the most prudent way, that is to recognise the theatrical aspect and recognise the tit—for—tat aspect. but also to recognise that iran is not in a position to engage in a full frontal military conflict with the uk or the united states. in this situation, acting prudently but letting them know at the same time that this cannot go on. so you think there is a sympathetic element to the way the uk has responded? a sympathetic element to the way the uk has responded ?|j a sympathetic element to the way the uk has responded? i think there is a prudent way. so far in the way the uk has responded but i'm surprised that after seizing the iranian

tanker and the iranian president made a direct threat of retaliation, that they won't expect in this. part of the way they talk about this in iranian media is they claim the oil tanker was being guarded by a naval ship. in that way it seems that the british were anticipating something like this but the iranians said it was a brilliant commando action and the british forces were engaged —— afraid to engage them, and i think thatis afraid to engage them, and i think that is a little too exaggerated. on the bigger picture, we know that iran and the us are at loggerhead and there have been many events there. is anyone actually talking or negotiating with the run at all behind—the—scenes? with iran? my

senseis behind—the—scenes? with iran? my sense is that there are many people trying to negotiate behind—the—scenes and defuse the situation because a full military confrontation in the golf is in the interest of no—one. i am almost confident that right now, as we speak, in spite of the bragging and the rhetorical firepower that iran keeps increasing, they are negotiating and he has most likely met with the us senator. and there are back channels through which communication is taking place. 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. 0fficials barred around thirty 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 recieved a hero's welcome on the streets of algiers after their victory in the african cup of nations. algeria beat senegali goal to 0 during last night's final in cairo, taking home the trophy for the second time in its history. british airways says it's cancelling flights to cairo for the next seven days, amid security concerns. the german carrier, lufthansa, is also suspending its flights to the egyptian capital until sunday. 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 at least some passengers to complete theirjourney, flying via other countries on other airlines into cairo. which seems to suggest that ba is happy for passengers to land at the egyptian capital's airport, just not on its aircraft. but ba does stress the safety of its passengers and crew is its priority. matt cole, bbc news, at london's heathrow airport. 0ur news reporter ramzan karmali sat down with me earlier and said the company's unilateral action has left more questions than answers. we have had passengers arriving at the airport getting their boarding passes, getting to the gates and being turned away. it's extremely unusual and also this was a decision made by the airline, by british airlines,

not any government official. and what's also is unusual is how temporary this suspension is. till the 27th ofjuly, so a very unusual move indeed. this is no — this has not come from the british government or the foreign office, although on their website they say in certain places of egypt, you should avoid some places. they also say there is a terrorism threat to aviation as well on that website, too. but, again, i must stress this was a decision made by british airways, and so this is very, very unusual and makes me ask more questions because the detail we got from british airways was very limited indeed. there are certainly a lot of questions around that. but what about other airlines, what are they doing? lufthansa, they have suspended forjust one month, just one night, really. we're going to have flights again tomorrow.

and thomas cook, in total about 415,000 british nationals travel to egypt, they travelled last year, and thomas cook was the main operator. they are going to carry on. they fly daily from manchester but they also fly from birmingham, newcastle and london gatwick. now the other one is easyjet, they take a lot of passengers from london gatwick and they put out a statement saying they're watching the situation, but they are going to carry on playing as well. so what do people do if they've got tickets or they've been affected? if you are a british airways customer, you will be able to get a full refund. you will be able to delay your flight and you could rebook on other flights and maybe complete it only with another airline. more likely to be someone like egyptair to get you to your destination like cairo or back to london because they are flying between heathrow and cairo. thank you very much. stay with us on bbc world news, still to come: standing not falling. how a skate park gives syrian

this is bbc world news, the latest headlines: one small step... the museum of air and space in washington marks the exact moment 50 years ago that neil armstrong stepped onto the moon. let's stay with that story. the moon landing itself was a wondrous technological achievement, but an equally astounding if less well—known feat was the live transmission of the images back to earth. an observatory in the small australian town of parkes, new south wales, known as ‘the dish', played a hugely significant role. i'm joined now by astrophysicist drjane kaczmarek, who's at the parkes 0bservatory in new south wales.

thank you so much for your time. first of all, can you explain the role that the dish behind you played in the moonwalk? there were actually two australian dishes that played a pivotal role in broadcasting that a signal to the world. one was honeysuckle creek in canberra which is no longer in operation. it ca ptu red is no longer in operation. it captured the first step and there momentous words that were broadcast and embedded in everyone's memory. but parkes behind me was a bit bigger and a bit more sensitive so eight minutes into the transmission, nasa decided to switch to our telescope with a clearer signal and they stuck with it for the 2.5 hours remaining of the moonwalk. was an extraordinary moment as well because there were very high winds, went

there? can you tell us about that? it was an incredible day here. the dish behind me weighs over 1000 tons but its actually not physically connected to the tower that it sits on. the day of the moon landing, they were gusts of wind over 100 kilometres hour that almost toppled the dish but they decided to go through with it and were able to successfully track the moon and share that story. tell us why it was so share that story. tell us why it was so dangerous to keep going, for the telescope and the people?“ so dangerous to keep going, for the telescope and the people? if the dish would actually fall over, everything is operated from within the tower so if the dish falls down, its going to actually crush the tower, the people inside of it and all the technology and hard work that went into building it. so it was a very touchy moment and a very ha rd was a very touchy moment and a very hard decision to make but i'm sure that nobody actually regrets the decision that was made in the end. of course they don't. there is an incredible mythology that's built up

around that moment. there are people there that still remember parkes 0bservatory‘s role in the moon landing? yes there were two people here that were here for that day. they were in charge of driving the telescope and making sure it stayed on target. they are here and they are still as sharp as ever. they are telling stories that would make anyone sit on edge because they are so anyone sit on edge because they are so amazing, how well they remember and are able to share their own experience of that very special day. it is quite incredible. i'm sure they have amazing memories. in terms of today, what role does the telescope continue to play? parkes has always been a research instrument. every single day we are doing silence —— science. we are tracking a star at the moment and its only rarely that nasa reaches out to us to help us track of space missions. we are still an operational instrument and we do

science that is leading the way in astrophysical research. take you so much for taking us through those memories of the parkes 0bservatory, helping broadcast the footage of the moonwalk 50 years ago. an incredible moment. thank you very much for your time. forensic experts have extracted bones from a burial chamber at the vatican in an attempt to solve the mystery disappearance of a 15—year—old girl in 1983. earlier this month, emanuela 0rlandi's family received an anonymous tip—off 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 0rlandi. it follows the opening of two tombs

in a vatican cemetery after 0rlandi's family lawyer received an anonymous tip—off pointing to the marble—topped graves. but the tombs turned out to be empty, and the chambers revealed only centuries—old bones of two german princesses. 0rlandi'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's probably italy's most enduring mystery. everybody has a theory about it, a favourite theory. it was the mafia. it was a paedophile ring inside the vatican, some say. it could have been the stasi, or islamic terrorists who wanted the release of popejohn paul ii's would—be assassin. and so there's enormous sympathy for the family and support for this vatican investigation that we're now seeing. yet the family has regularly appealed to the vatican to provide more information, and some say

the holy see knows more than it is telling. 0rlandi's father died still wanting answers. 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. a skate park built by a german charity is helping to change children's lives in a damascus suburb. eight years of civil war in syria have had a traumatic effect on children, and the park aims to develop their sense of self—determination and promote development. the skate park is also a public green space encouraging community engagement, as gail maclellan reports. mohammed doesn't care how many times he falls off his skate board. he is happy to learn, and probably lucky to be alive. translation: i hurt my arms, legs and shoulder, until i learned

how to do it. he says it took a while to get to grips with the board. at first, we used to sit on it. we didn't know how to stand. and then the volunteers came and told us these are skateboards. we didn't understand in the beginning, but they taught us, and now we know how to do it. mohammed was displaced from an area in eastern ghouta that saw fierce fighting in the syrian conflict. the skate park was built a month ago by the german ngo skate aid, which has transformed a public square in quadsaya into a playground for the children. their aim, they say, is to help children traumatised by years of conflict and violence. 0ne really important thing is, that fits very importantly in these countries with conflict, skateboarding shows the most important thing in their lives is to have to stand up one more time than you fall down.

mohammed might now be safe from a past of bombs and fear, but still, learning how to keep standing is a precious gift. take a look at these extraordinary pictures from the united states. it shows the moment a man took drastic action to escape a fire in a high—rise building in philadelphia. he can be seen scaling down multiple storeys with a helicopter spotlight guiding his way. the unidentifed man, who's been dubbed a real—life spider—man by local media, reached the ground safely. 0ur our top story this hour, the exact moment the first human stepped foot on the moon 50 years ago has been ——

has been marked with a celebration at the museum. people celebrated a new year's at the museum. people celebrated a new yea r‘s style at the museum. people celebrated a new year's style countdown. much more to come. stay with us. hello. saturday brought us a day of sunshine and heavy showers. sunday will be the drier day of the weekend for many of us. now, this was the picture on saturday in norfolk. we had some huge shower clouds around, thunderstorms as well. those showers have now eased away towards the east. so what we're left with as we head through the day on sunday are long spells of sunshine and further rain. that's going to be arriving across north—western parts of the uk later on in the day. from the word go, a lot of dry weather with some sunshine, lighter winds than we had on saturday. through the morning, the winds pick up and the cloud increases across northern ireland, ahead of some rain arriving in the middle of the day. that'll spread across the western half of scotland in the afternoon. heavy, wet and windy here in the north—west. eastern scotland and the bulk

of england and wales stay dry and fine all day, with temperatures about 20—25 degrees or so in the sunshine, typically the high teens where you've got cloud and the rain. and that rain is likely to affect the final day of the open at royal portrush. dry, i think, through the course of the morning, but things will turn pretty soggy during the course of the afternoon. through the afternoon into the evening, the attention turns to northern ireland and western scotland in particular, where rainfall totals are really going to be mounting up. could be some localised flooding as we head through into the early hours of monday. western scotland and also north—west of england seeing some of those torrential downpours. it's going to be quite a humid night, actually, first thing monday the temperatures already in the high teens. through the day on monday, the story improves and the rain we've got initially is going to work its way gradually towards the north. so for much of england and wales, i think, a dry day. again lots of sunshine, and with that south—westerly wind, the humidity and heat increasing. there could be a lot of low cloud around some of these irish sea coasts. temperatures up to about 29, possibly 30 degrees towards the south—east on monday. even across scotland and northern ireland, we've got those temperatures in the mid—20s. but through the middle part of this week, the heat is really going to be

rising, and across much of central europe that heat will be setting in, and we could break the all—time temperature record in paris with 41 celsius possible by wednesday. that heat pushing up towards the uk. so into tuesday, then, another warm day everywhere. we could well see those temperatures above 30 degrees for several places across southern and eastern england. hot weather across the uk. it is looking dry for most of us, but increasing humidity, and that means there could well be some heavy and potentially thundery showers through the middle part of the week. so showers around in the north and the north—west, warm and dry towards the south—east. do keep an eye on the latest forecast. bye— bye.
