The us secretary of state mike pompeo is on his way to the middle east for talks with both saudi arabia and the uae and an offer to negotiate with iran. There have been days of extreme tensions between washington and tehran. It includes reports of an american cyber attack on iranian weapons, apparently in retaliation for the shooting down of a us drone. Our washington correspondent Chris Buckler reports. Having backed away from military strikes, america is trying to show its not afraid of conflict with iran. Officials say they launched cyber attacks, which they claim disabled iranian systems controlling rockets and missile launchers, exactly the kind of hardware that was responsible for shooting down an american drone over the gulf. With tehran showing off the wreckage and President Trump threatening iran with obliteration if this ends up in confrontation, the International Community is increasingly worried. Everybody must keep nerves of steel. It is absolutely essential to avoid any form of escalation. The world cannot afford a major confrontation in the gulf. The British Foreign minister Andrew Murrison has been meeting diplomats in tehran, trying to urge calm and diplomacy. But there seems little appetite for that in the iranian parliament, where they chanted, death to america. Meanwhile, with its build up of military might in the gulf, the us appears to be doing all it can to demonstrate that its ready for war. Neither iran nor any other hostile actor should mistake us prudence and discretion for weakness. No one has granted them a hunting license in the middle east. There is a clear divide inside the white house. President trump was the one who called off the retaliatory strike but most of his senior advisers wanted them. That has resulted in a mixed message being sent to tehran. At times, the Trump Administration appears to be tentatively offering a hand of friendship, even as it shakes its fist. We are prepared to negotiate with no preconditions. They know precisely how to find us and im confident that at the very moment theyre ready to truly engage with us, we will be able to begin these conversations. The us secretary of state is now on his way to the middle east in an attempt to calm waters in the gulf. But with concerns of further attacks following explosions on tankers and iran threatening to breach the terms of its internationally agreed nuclear deal, relationships between tehran and washington will be tested, if any exist at all.

Ekrem imamoglu has brought in the hope they craved with his optimistic message, rebuffing attacks with smiles and he won by a landslide. Translation i asked god for this result to bring good fortune to our nation in istanbul. He protected 100 years of democracy in this country. Thank you, my fellow citizens. This result does not mean a new page, this means a new beginning for istanbul. As votes were counted, his victory was clear against a former Prime Minister with near total dominance over the media but in concession, a conciliatory note. Translation i hope that our dear friend will serve istanbul well and we will do our best to help them accomplish his work. Recep Tayyip Erdogan has towered over turkey as mayor of istanbul himself, then Prime Minister and president , a key global figure in everything from security to syria, he has polarised turkey. After claiming irregularities after the first mayoral elections in march, he pushed for a rerun. This fresh loss will prompt talk of the beginning of his end.

Youll find analysis of what the election result means for president erdogan, and a profile of the mayor of istanbul thats all at bbc.

Mauritanias Electoral Commission has announced the ruling partys mohamed wilid ghazouani has won the president ial election with 52 of the vote. This means the 62 year old former head of domestic security has won outright with no need to hold a second run off. Opposition candidates say the election was marred by irregularities and they intend to contest the result. The United Nations has called on the people of ethiopia to show restraint following the assassinations of their army chief and a provincial leader, during an apparent local coup attempt. Hours after the president of the northern Amhara Region was shot dead, the head of the army, sara ma konen , was killed by his own bodyguard in addis ababa. Police in india say they have recovered seven bodies believed to be those of a british led group of mountaineers who went missing in the himalayas a month ago. They were hit by an avalanche near the base camp of the countrys second highest peak, nanda devi. The Search Operations for the last missing climber starts again on monday. Hundreds of thousands of people have gathered in the czech capital, prague, to demand the resignation of the Prime Minister, andrej babis. The billionaire businessman is facing a criminal investigation over alleged European Union subsidy fraud worth more than two million dollars. He denies any wrongdoing and says the allegations are politically motivated. The bbcs rob cameron is in prague. Letna plain, usually an empty and rather non descript strip of land close to sparta prague football stadium, and the sight of what was once the Worlds Largest statue of stalin but now packed with a quarter of a million protesters from cities and towns, young and old, united in anger at their Prime Minister, andrej babis. Translation i was here at letna in 89. I am 66 years old. Im of pensioner and im here because i dont want my kids to grow up in a country where someone being prosecuted for a crime can be Prime Minister. Its really important to have these demonstrations to. To change something. The choice of letna was a deliberate nod to the november 1989 velvet revolution. Back then, this was the scene of the largest protests against the communist regime. In fact, that regime came tumbling down just days later. These protests, against a democratically elected leader, are also being spearheaded by students who formed an initiative called a million moments for democracy. Organisers had promised that this would be the biggest public demonstration in this country since the 1989 fall of communism, when half a Million People packed this very square to protest against the regime. And perhaps the numbers today are not that big but it is certainly an astonishing achievement for what was, until relatively recently, a small student initiative. The question is, though, does it change the political reality in the Czech Republic . Prime minister andrej babiss ano party still tops every opinion poll and won the recent european elections. Amidst an economic revival, many people are willing to give him the benefit of the doubt. And theres a general sense of something more at stake here, that the hard won freedoms of the 1989 velvet revolution are gradually being eroded, chiefly thanks to the powerful businessman who now runs their country. Rob cameron, bbc news, prague. Thousands of runners and cyclists have taken part in a charity race in thailand, marking a year since a group of boys and their football coach became trapped in a cave complex. The team was eventually rescued 18 days later in a mission that caught the attention of the world. Kathryn armstrong has more. The start of a race in remembrance of a rescue that captivated the world. These are some of the 12 boys who, a year ago, entered the vast tham luang cave system in northern thailand with their football coach to relax after training. A trip that went horribly wrong. Flash flooding left the team trapped inside for more than two weeks, with little food or water, before diving experts were able to rescue them. The death of a former Thai Navy Seal and rescue volunteer, who ran out of air while returning through the caves, highlighted just how perilous the mission was. A year later and the boys have had their story chronicled in books, documentaries, and a netflix production is also in the pipeline. Translation its indescribable. My life has changed a lot. Translation i feel thankful for all the officials who on this day last year spent their time to help me and the boys so that we got out safely. I thank you very much. Also among those taking part in the charity race, from the still closed caves to the village where the rescue took place, were some of the experts involved. I think its important we never forget what happened injune and july last year and its just really about people coming together and enjoying the day. Its hoped the race will be an annual event, with the money raised going to the redevelopment of the cave complex. Kathryn armstrong, bbc news. Thousands have added in the chinese city to celebrate. Although the team was brought out alive, one of the rescue divers died in the operation. His efforts are honoured by a shrine where people leave their prayers.

It was closing time for checkpoint charlie, which, for 29 years, has stood on the border as a mark of allied determination to defend the city. You yet this is bbc world news, the latest headlines americas secretary of state heads to the middle east to discuss iran with us alllies massive celebrations in the turkish city of istanbul as the opposition wins a re run of the mayoral election. Its a major setback for president erdogan. For more now on that story Karabekir Akkoyunlu is from sao paulo university. This is his take. It is a big loss, for various reasons. After losing istanbul narrowly in the first election, on the 31st of march, erdogan faced a choice, he would either accept the loss of istanbul, which is the cash cow of his economy and the big symbol of his regime in government really, but maintain his respect for democracy and democratic legitimacy, which he always emphasises this sanctity of the ballot box or he would try to hold onto istanbul by undemocratic means, if necessary, and risk that democratic legitimacy. What happened, by cancelling this first election, and then losing the rerun by a humiliating margin however, is, astonishingly, we now see erdogan having lost both istanbul and jeopardise his democratic legitimacy, which is quite astonishing to see a series of misjudgements from a political tactician, a seasoned politician, such as erdogan. What that means, the same time, what that reveals is that the akp machinery is no longer as robust. It is actually taking in water. And we are going to see the results or the consequences of that in the next days and weeks. What consequences will that be for the party . Are we going to see splits in his ruling party . The first things we have to watch and expect to hear will be the establishment of one or maybe two new Political Parties by former akp bigwigs and founders, including former president , abdullah gul, and a Prime Minister, ahmet davutoglu. So we may see the splintering of the akp. Of course, turkey has become a president ial system, that means parliamentary politics does not define turkish outcomes as they used to do. But in that level as well we have a newcomer. Let us look at the winner, ekrem imamoglu, what kind of leader is he going to be . We will see how hes going to be. Based on what he has done so far, he has managed to build an inclusive image, an inclusive platform at a moment when turkey is suffering from extreme polarisation and division. That has appeal to a lot of voters from across the political spectrum. If he manages to maintain that platform and maintain that image, he is going to be the person that will keep rising and ultimately, maybe in 2023, the person to take on erdogan in the next president ial election. At least 1a people were killed and fifty others injured in western india when a thunderstorm caused a huge tent to collapse.

At the g20 meeting injapan this week, all eyes will be on President Trump and president xi as they meet to try to defuse the trade war between the worlds two biggest economies. President trumps enthusiasm for slapping tariffs on imports is seen by many as a major threat to prosperity around the world. But what do american businesses make of their president s apparent enthusiasm for trade wars . Samira hussain has been speaking to some of them in pennsylvania. The fortunes of york pennsylvania were built on manufacturing. Heavy industry remains essential to the local economy. And it is communities like these that acutely feel the impact of President Trumps trade wars. Bob wilsons business is selling electrical wire and cable. It has been hit by duties on the material it buys overseas and the finished product he sells to his customers. Plans to hire two new fulltime staff have been put on hold. Not knowing what the future is going to hold, those plans have since been put on the shelf. Up until last year, bob wilson was a ca rd carrying republican. He says the party has forgotten its pro trade routes. We reallyjust truly dont know whats going to be happening. It seems to be, changes from day to day, depending upon a tweet. The uncertainty is particularly difficult for Small Companies to weather but york is also home to some big manufacturers who have already said theyve been badly hurt by tariffs. So what our businesses are really looking for to be successful is a stable, predictable business landscape. Theyre not looking for drastic policy changes, theyre not looking for uncertainty. Just down the road from bobs cable business, sparks are flying at this sheet metal company. Despite the fact that the cost of tom mckees Raw Materials have gone up, he remains steadfast in his support for President Trump. Rome wasnt built in a day, things dont change overnight, and we have not been on a level Playing Field for years and the man down in washington, dc, you know, he is what he is, but i think hes starting in the right direction. As well as americas manufacturing base, places like york also make up President Trumps electoral base and will be key in the next election. Americas industrial heartland gave President Trump his first term in office and although there are those that believe these trade disputes are hurting the us economy, mr trump is betting it will win him enough support from Small Companies and will give him another four years in the white house. Samira hussain, bbc news, york, pennsylvania. For over a century admirality arch has been one of londons most distinctive landmarks, a gateway to the mall and buckingham palace. After being sold as part of government cost cutting, it will re open soon as a luxury hotel. But Building Work revealed that the arch was an entrance to a network of secret tunnels. Mark easton went to have a look. Familiar backdrop to a century of british ceremonial the secrets of admiralty arch are now being unearthed. Weve been granted exclusive access to see whats happening to one of londons most famous landmarks. Inside, edwardian opulence and memories of old battles. The ghosts of Navy Commanders haunt the corridors. Winston churchill, louis mountbatten, reminders that admiralty arch was the residence of the first sea lord when britain ruled the waves. It is also where ian fleming, working for naval intelligence, created james bond, and down in the basement one discovers a network of secret tunnels stretching beneath westminster, filmed for the first time. There are strange corridors, bunkers with heavy doors and combination locks. The spirit of the cold war lives on in the basement. Little is known about who or what happened down here, but we do know about their subterranean billiards room. From the coronation of george v to the queens diamond jubilee, the arch has spanned the state processional route for 100 years, but in 2012 it was sold for £60 million as part of government austerity measures, and not everyones happy that this significant public building will soon advertise itself as a waldorf astoria hotel. During a debate in the house of lords, one peer feared security risks, describing the sell off as privatisation gone mad. Another worried that the white ensign flown here on state occasions might be replaced by the corporate flag of an American Hotel chain. But the last first sea lord to live in the arch is confident this buildings proud heritage will be protected. I think the old and bold who are now no longer with us would be disturbed to think that admiralty arch was going to become an hotel. Im not. I couldnt be more pleased that this building is going to be properly looked after. So was that found here . Yeah, we found this here. The new owner, spanish investor raphael serrano, tells me he understands he is merely custodian of a much loved corner of britain. It is our obligation to make sure that the building looks as it is, a genuine iconic building, and with respect of the british traditions and the location where the building is located. So it wont have waldorf astoria all over it . Not at all, not at all. The arch is a grade one listed building and its foundations cannot be touched, so a vast cavern is being dug on the edge of Trafalgar Square to house the essentials of a modern five star hotel. Underneath there will be a ballroom, swimming pool, spa. It must be some hole it is, it is. Its a fairly big hole. It will be when weve finished. Once the only people who could access this building were civil servants, sailors and spooks. But now the dusty old corridors are being restored to theirformer glory as the secrets of admiralty arch are revealed at last including, of course, perhaps londons most splendid view. Mark easton, bbc news, admiralty arch. France is renowned for being the home of style and culture and more than 80 men have been battling it out in the french beard championships.

Not everyone will see them but, where you do, an increased risk of some flash flooding around. Later this week though the sunnier side of summer will return. Most places dry, blue skies overhead, but the highest of the temperatures will be later in the week, friday into saturday in particular. Out there at the moment, weve got some fairly humid air with us as this weather system works its way northwards. Weve seen some thunder and some lightning attached to this rain, pushing into parts of scotland for the morning. Some of the rain here could be heavy and persistent, with quite a south easterly breeze to go with it. There could be minorflooding, as i said, and that could give some travel disruption. Further south, big puddles left in the wake from the overnight storms. And look at that temperatures starting the day at around 18 celsius in central london. The atmosphere for monday is finely balanced. Weve got the rain pushing northwards across scotland, still with some rumbles of thunder. Away from it, though, when we see the sunshine come out, it will feel pretty warm, especially in the south. Not as warm as the weekend across northern and western scotland. More cloud, still some outbreaks of rain, and a breeze. Heavy, thundery rain into the evening and eastern scotland but then another batch of storms out from france which could be more severe, particularly across parts of central, eastern england. Uncertainty about where they will be but frequent lightning, risk of flash flooding and some gusty winds to go with it, and a fairly oppressive night across the country with humidity levels continuing to creep up. It will be a humid start to tuesday, impacts from the storms across Central Eastern england in particular. Maybe Northern England during the morning rush hour, too. They gradually ease away and things gradually turn quieter as we go through tuesday. One or two isolated storms cant be ruled out but most are becoming dry. A fair bit of cloud but, when the sunshine breaks through, with increased humidity, temperatures 25 27 in the south east corner, 22 23 in western parts of scotland. A ridge of High Pressure builds in for wednesday, doing a few things, clearing away some of the cloud, a lot more sunshine around, dropping the humidity levels in the north, cooling things in eastern coasts. Chance of one or two storms towards that south western corner but they clear through as we go through towards the end of the week. High pressure builds in, and pushing to the east of us, dragging our air in off western parts of europe where we could see some record breaking heat over the next few days. For us, here we could see temperatures climb to 26 to 28 degrees in western scotland, above 30 in the south.
