this is bbc news. the headlines: the british foreign secretary has warned there will be "serious consequences" if iran does not hello and welcome. release a british—flagged tanker the uk's foreign secretary seized in the gulf, and the uk is warning there will be serious government has advised shipping consequences if iran doesn't release to stay out of the area too. a british tanker seized in the gulf with 23 crew on board. tehran says the vessel was breaking maritime navigation rules. the stena impero's owners say they have been unable the stena impero was heading to contact their vessel. for the saudia arabian port ofjubail but contact was lost with the ship as it passed through the strait of hormuz tracking data shows it aid agencies are calling deviating from its intended route. on international governments iranian media is quoting military to speed up their response officials saying it is being taken to the ebola emergency to the port in bandar abbas for further investigations. in the democratic republic of congo. our diplomatic correspondent more than 1,600 people james robbins reports on the latest have already died there. escalation of tensions the world health organization has declared an international public health emergency. in the region. extremely hot weather has started to hit north america, with temperatures of around 38 this is stena impero, degrees celsius expected at the weekend. meteorologists warn built only last year, the vulnerable could be at risk. british flagged, 183 metres long, the heatwave now in the hands of iran, could affect about 200 million together with her 23 crew. people in major cities. routine satellite tracking of the tanker shows her under way from the emirates of fujairah, around midday, heading north,

staying well inside international waters of the gulf — until this happened. just after three o'clock, the 30,000 ton tanker diverts seriously off course. her last known movement was around four o'clock, inside iranian waters. the owners, stena bulk and northern marine management, say in a statement: and then news tonight that a second ship had been seized, the mesdar, liberian registered. foreign secretaryjeremy hunt condemned the seizures as unacceptable, saying he was extremely concerned. and president trump

confirmed the news. we don't have very many tankers going in but we have a lot of ships that that are warships and we will talk to the uk. and we have no written agreement, but we have an agreement. they have been a very great ally of ours. so we heard about it. we heard it was one, we heard it was two. and we'll be working with uk. these are pictures released by iran said to be showing pictures of the islamic revolution guard corps circling another vessel, the riah, in recent days. the guard corps appear to use these armed boats and sometimes helicopters to force ships into their waters. their efforts to seize british vessels were intensified after royal marines and gibraltar police boarded and seized a tanker, grace 0ne. it was carrying iranian oil in gibraltar waters, suspected of heading for syria, in defiance of eu sanctions. iran called this piracy, but that's dismissed as nonsense by britain. that was followed by an incident

in the gulf when the british frigate, montrose, moved into protect the tanker british heritage in the gulf. but the threat to british vessels was spelled—out earlier this week by iran's supreme leader. translation: evil britain commits piracy and steals our ship. it's an act of piracy. of course the islamic republic will not leave such evil deeds unanswered. there will be a response at the appropriate time and place. so the iranian guard corps will consider today's seizures a significant victory in a crisis which has been escalating for months. a former head of the royal navy, lord west, says britain simply has too few ships to provide escorts for merchant vessels. my biggest concern, i have to say, is i find it extraordinary that british flagged ships, tankers, particularly,

are steaming on their own into this area of danger. i mean, think we should be trying to de—escalate, but you can't allow thugs and effectively criminal actions by a nation against your nation. with american warships the dominant naval force in the gulf, british cooperation with washington will be key if protection of a vital trade route is to be improved. but for now the immediate focus will be on getting iran to free the stena impero and her crew. the british foreign secretary jeremy hunt had this to say about the seizure of the tanker. i have spoken to secretary of state pompeo in the united states earlier this evening about the situation. i've tried to talk to the foreign minister of iran, but understand he is on a plane. i will speak to him as soon as i can. this is completely unacceptable. freedom of navigation

must be maintained. we will respond in a way that is considered but robust and we are absolutely clear that if this situation is not resolved quickly, there will be serious consequences. british ministers have issued new guidance for shipping operators. 0ur correspondent simon jones has the details. the government's emergency committee known as cobra met well into the night. they have released a statement after that meeting describing the seizure of the british tanker as "completely unacceptable. " they say it goes completely against international maritime rules. they say they are deeply concerned about tensions in the area and interestingly, they‘ re suggesting british shipping should stay out of that area for the time being. that is quite a development when obviously there are a large number of tankers passing through, particularly in the international community. there is also in this statement talk again of a robust response and consequences for iran. it doesn't spell out exactly what they mean by that,

there are no deadlines, not saying to tehran you have to return the tanker by a particular time, they aren't wishing to escalate things in that way. have they ruled out using force? 0ur north america correspondent peter bowes told me what's led up to the latest developments. this seems to have been going on for a number of weeks. especially in relation to the drones that we've been hearing about, and president trump, according to his own words, said "we came within ten minutes," the us came within ten minutes of launching a military action against iran after shooting down one of america's drones. in the last few days the us saying it destroyed one of iran's drones although iran says it doesn't know anything about it. so, certainly, yes, a tit—for—tat feeling about what is going on. but the events of these last few hours late on friday really seem

to have ratcheted up the tensions that exist not only between the us and iran but also the tensions between iran and the united kingdom. what we heard from president trump, how he is standing by the united kingdom referring to that close relationship, and describing the uk as a close ally, talking about the military vessels the us has in the region and by implication offering to help the uk in whatever way the us and the uk might want. although, as again we've been hearing, diplomatic discussions and actions seem to be the preferred course of action, at least for the foreseeable future. in amongst all of this we've been hearing about a us troop deployment to saudi arabia — can you explain whether it is connected? it seems like it is certainly connected to the overall tensions and problems that we are seeing in the gulf, especially

that crucial shipping lane and the dangers that are now posed to vessels in international waters. the us defense department has announced a deployment of troops to saudi arabia where previously for the past few years there haven't been any troops. we understand 500 in number, patriot air defence missile systems, the f—22 stealth fighters will also be deployed to a base in saudi arabia. to, according to the us, protect american interest but also respond to what it describes as "credible threats" in the region. let's get some of the day's other news. china's state media says ten people have been killed and i9 wounded after an explosion at a gas plant on friday afternoon in china's henan province. mobile phone footage showed billowing smoke rising from the site, as well as shattered windows on nearby buildings. an investigation into the cause

of the blast is underway. the prime minister of kosovo has resigned after an eu—backed war crimes court summoned him for questioning as a suspect. ramush haradinaj led the kosovo liberation army during the war for independence from serbia twenty years ago. he's been tried and acquitted twice by a separate united nations war crimes tribunal at the hague. algeria have lifted the africa cup of nations for the second time, defeating senegal i—0 in the final in cairo. the victory sparked riotous celebrations in the stadium, back home in algeria and among the large expatriate community in france. aid agencies are calling on the world to speed up its response to the ebola emergency in the democratic republic of the congo. more than 1,700 people have already died there — and the world health organization has declared an international public health emergency. 0ur correspondent anne soy is there. goma, in the east of the drc. a bustling transit city, home to more than 2 million, mostly traders who are

constantly on the move. an outbreak of ebola here could be devastating. as they trudged on up north, the city prepared. last weekend, its health systems were put to the test. these brothers say their uncle drove the bus on which an ebola patient travelled. the uncle later paid them a visit. now they have come here to be vaccinated. they told us that this vaccine don't prevent you at 100% from ebola. that's why i am still afraid a little bit. people who have been in contact with patients and those around them are advised to get the jab. so far in the democratic republic of congo, more than 165,000 people have been vaccinated. this is still an experimental vaccine, but experts believe that it has played a big role in preventing the further spread of the disease. rwanda, just beyond this

gate, is on alert. the conditions here showjust how bad things could get if a bigger outbreak hit the city. the livelihoods of all these people depend on cross—border trade. and the world health organization has advised against closing borders because in any case, it doesn't stop the spread of ebola. experts say it could even make an already complex outbreak worse. it would hurt the congolese people who, if they can't move in a formal way over formal border crossings, will find informal ways, which will make detection of contact much harder if they cross. and of course, it will make the movement of goods and healthcare workers and humanitarian aid workers much harder as well. aid agencies say they need more funds to help keep notjust these people safe from ebola, but also many others around the region. as long as there is an outbreak in the drc, trade and travel means it could spread to neighbouring

countries and beyond. stay with us on bbc world news, still to come: the washington monument turns into apollo 11 as america marks the 50th anniversary of the moon landing. 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.

from the iran nuclear deal which promised economic relief for the country. the importance of breaching the deal is that we are in the current situation we are because of that. iran not getting the economic relief it was promised through the deal is why iran is now, a year later, after practising sort of strategic patience, not doing anything provoking, complying with the deal, has no benefits. so now we are seeing iran shift strategies over the last month or so, or two months 01’ the last month or so, or two months orso, the last month or so, or two months or so, because they haven't gotten any relief in terms of sanctions, in terms of the economy, and that's what they were promised. terms of the economy, and that's what they were promisedm terms of the economy, and that's what they were promised. if this is about more than what is happening with uk, isn't the problem that iran is really playing into donald trump's hand, donald trump and say i'd told you, iran is a bad actor,

music: god save the queen. the so—called special relationship, on full display during president trump's recent state visit to britain. but even then, he was looking beyond the conservative party leadership contest, saying boris johnson would make an excellent prime minister. but it hasn't always been as warm as this meeting at the un two years ago. in the past, they have clashed over donald trump's description of no—go areas in london and over attempts to ban people from some muslim countries. i spoke to him yesterday... however, at the white house today, nothing but praise. i like borisjohnson, i always have. he's a different kind of a guy, but they say i'm a different kind of a guy too. we get along well. i think we'll have a very good relationship. it won't have escaped the president's notice that the resignation of the british ambassador to the us was prompted by boris johnson's failure to fully back sir kim darroch after it emerged that the diplomat called the trump administration clumsy and inept in leaked diplomatic cables.

and while mrjohnson called the president's controversial tweets this week totally unacceptable, he didn't go as far as others in branding them racist. if you're the leader of a great multiracial, multicultural society, you simply cannot use that kind of language about sending people back to where they came from. boris johnson is undoubtedly feeling the love from the trump administration right now, but he will know, as many other world leaders already do, that with this president, a love—in can turn into a falling out in the blink of an eye. gary 0'donoghue, bbc news, washington. 50 years ago, america was on the eve of apollo 11 touching down on the moon and us astronauts becoming the first to step foot there. all week there have been events to mark the anniversary and look back at the space race which led to this new frontier. in washington crowds

have turned our to see a massive celebratory display. here's nick bryant. in a week that's highlighted the deep divisions in washington and america, a gigantic reminder of a unifying national mission. apollo 11, projected onto the washington monument for this back—to—the—future celebration. and at ground level, a coming together of the american generations. i want to be an astronaut one day. you want to go to the moon? yes. do you think you'll ever get there? i don't know. it's been pretty cool to see it through youtube. so to be here and be alive, it's brand—new to me. to me, it'sjust as exciting as when we did it the first time. it was beyond remarkable. it was almost the type of thing that you didn't think could possibly come to be. liftoff! we have liftoff. conquering new frontiers has always been an essential part

of the american spirit. but it was conquering the soviet union that made the space race such an urgent national priority. in those cold war years, soviet cosmonauts had outpaced american astronauts. the moon mission was also about a global ideological battle. the space race was all about the cold war. the whole reason for the race to the moon was to beat the soviet union and prove that the western capitalist model of government was better than the soviet model. and that was a serious issue in the early ‘60s. but the united states beats the soviet union to the moon in 1969, tremendously undercuts the legitimacy of the soviet union both internally and externally, and i think contributes to the collapse of the soviet union 30 years later. taking the stars and stripes to the moon was, surprisingly, something of an afterthought. it was purchased from a local hardware shop. as you talk to us from the sea of tranquillity... and though the moon mission was launched byjohn f kennedy,

it was his one—time rival richard nixon who was president at the time. for every american, this has to be the proudest day of our lives. the moon landing came at the end of a tumultuous decade. the ‘60s brought the struggle for black equality, the vietnam war, the assassinations of the kennedy brothers and dr martin luther king. here, finally, was a moment that transcended national strife. there's been a wave of space—age nostalgia, marking a glorious, near—hypnotic moment when "america first" had a very different connotation. nick bryant, bbc news, washington. we will have more on that anniversary on sunday on bbc news. a reminder of our top story. britain has advised its vessels to stay out of the strait of hormuz after iran's revolutionary guards seized a british—flagged tanker. the foreign secretary called the seizures completely unacceptable and warned tehran of serious consequences unless the british—flagged stena impero was released. butjeremy hunt ruled

out military action. much more coming up on bbc news. stay with us. hello there. it felt as if summer had taken a break on friday. it will return though as i'll show you later in this forecast. but over the last 2a hours we have seen some really heavy downpours, that picture came from a weather watcher in staffordshire, late on friday afternoon. the radar picture shows the way in which these pulses of very heavy rain flung themselves across the british isles, with some flashes of lightning, some rumbles of thunder, and the last vestiges of this wet weather still with us as we start off saturday morning. some heavy rain still across the far south—east. some patches of rain elsewhere as well. all tied in with this frontal system which is clearing away, so that will allow for things to improve a little through the day ahead, but low pressure still in charge, so while there will be some spells of sunshine, there will also be some showers, some of which could be

heavy and thundery. but it is quite a soggy start across the south—east of england, and that rain should clear away fairly smartly through the morning. rain though hanging back across shetland for a good part of the day. for the majority though, it is that regime of sunny spells and heavy, thundery downpours, although for northern ireland, a much drier day in prospect with patchy cloud and sunny spells, 20 in belfast, 22 in plymouth, 2a in london. those showers should quickly fade away during saturday evening. into the early hours of sunday we will be left with clear, starry skies, maybe the odd mist patch, and it will be a little cooler and fresher with temperatures getting down to between 11—14. sunday then starts off on a fine, dry and, in many places, sunny note. the further south and east you are the better the chances of holding on to that fine weather, but for northern ireland, western scotland, far north—west of england, maybe north—west wales will see outbreaks of rain and strengthening winds through the day. still some wet weather around the northern half of the uk on monday. that rain tending to retreat northwards, further south some spells of sunshine, and things start to warm up. temperatures could get to 29, possibly 30 degrees, but that is not the end of it because across iberia and france, a significant heat wave will be

developing through early part of next week, and some of that heat will waft its way northwards. some places likely to get to around 3a degrees. the north—west of the uk always likely to see some outbreaks of rain at times, but even in edinburgh we are looking at highs of 25—26, some areas of cloud flirting with western coast at times, further south and east that's where we'll have the highest temperatures — 33—34, but the chance of some thunderstorms 00:28:20,344 --> 4294966103:13:29,430 later in the week.
