In the Tour De France. Hello and a warm welcome to Bbc News. Days after the assassination of its president , haiti looks to be heading into a deeper political crisis. There are reports the countrys lawmakers have nominated the head of the senate, Joseph Lambert, as Interim President , in a move that a rival Political Faction including Acting Interim prime Minister Claudejoseph says is unconstitutional. It comes as haiti requests troops be deployed from the United Nations and the united states to help secure key infrastructure. The us says it has no plans to provide Military Assistance at this time but has sent Fbi Agents to help investigate, as our North America Correspondent Peter Bowes reports. Some of the men the haitian authorities say assassinated the Countrys President , on parade for the media hours after a long gunfight with Security Forces. The police also displayed some of the weapons they seized. Three members of the gang were killed and eight are on the run. Gunfire. The citizens of this impoverished nation are angry. Some members of the public have joined in the search for those still at large. As well as former colombian soldiers, the gang also included two americans of haitian descent. The us says its going to help with the investigation. In response to the haitian Governments Request for security and investigative assistance, we will sending senior Fbi And Dhs officials to port Au Prince as soon as possible to assess the situation and how we may be able to assist. The nation is now facing a constitutional crisis, with no president or working parliament. Claudejoseph, the interim prime minister, is in charge for the time being. This is the poorest nation in the Western Hemisphere with a raft of problems spiralling inflation, intense Poverty And Gang violence. But why a foreign Hit Squad would be deployed to kill its president remains a mystery. Peter bowes, Bbc News. A short time ago, i spoke to Amy Wilentz a journalist who focusses on haiti. She told me that much of the international community has grown fatigued of assisting haiti. I think weve just heard so far basically law enforcement, intelligence, fbi personnel. I dont think the united states has yet committed any troops to haiti i dont see why it would at this point. I havent seen in listening to people and looking at videos on the ground, i have not seen a kind of chaotic unrest that even compares to what there was before Jovenel Mois was assassinated on the ground so im unimpressed by people gathering outside the Police Station and shouting and yelling about the guys who were arrested in the investigation into the assassination. There is a fractious history between haiti and the united states. President trump supported Jovenel Moise. President biden allowed him to continue his presidency, if you like. Does this change the situation and the relationship between the us . Well, i think it has it has certainly gotten the attention of the united states, whereas they were sort of hoping that they could just getjovenel through to an election that would look like a real election, that might actually be one although most of us doubted that. They hoped that that could happen, even with this guy who was really not an effective Executive Or Leader of his country. But now, of course, they cant rely onjovenel to sort of shepherd through a seeming election and now theyre stuck and they dont know what to do, so thats gonna be hard for the us and the international community in general the un, the organization of american states, et cetera. You mentioned the un this request has gone to the un for Security Forces to be deployed to haiti. Do we expect to see international foreign troops on the street of port Au Prince . Well, i dont know obviously but i think the un is thoroughly sick of haiti. They had a 13 Year Peacekeeping Force there that got in a lot of trouble in a lot of ways the last thing being the cholera epidemic, which the peacekeeping forces brought into haiti, so i think they dont really want to get entangled again. I think most outside forces dont want to get militarily entangled again in haiti if they can avoid it. Journalist Amy Wilentz speaking to me earlier. In a major escalation since international troops started withdrawing from afghanistan, the taliban have seized a key border crossing. Islaam kalaa is one of the biggest Trade Gateways into neighbouring iran, generating around 20 Million dollars a month for the afghan government. Afghanistans Defence Ministry says Security Forces are trying to recapture the site. From kabul our chief international Correspondent Lyse Doucet has more on the situation across afghanistan. The city springs to life. Kabul� s oldest market, one of its busiest. Painters, masons, plasterers, they all come here to find a days work. Its always been tough, but much tougher now. Translation the. Foreigners are leaving. We are worried about the war. Its everywhere. People are fleeing into the cities, but there is no work here. We are under so much pressure. This fridge. And they sold all their crockery . Yes. All their. 7 all equipment. All their pots . Selling up, upping sticks. More afghans are leaving. A street of second hand goods. Nusrat set up shop here when his job ended with the us military. Lots of afghans were working with them, now they are jobless. A lot of them, they are planning to go out of afghanistan because of their security and because of a lack ofjobs. You know, the americans said its time to go, its 20 years, thats enough. For what purpose they come in and for what purpose are they going . What is the conclusion . If they didnt gain something, they didnt build something for us, they didnt make the security for us, why they are coming . Tea and treats in the city centre. Sweet moments for afghans who can afford them. The kind of life many young afghans here, men and women, want to live. Growing insecurity already threatens it. We are hurrying, just coming to the restaurant, coming to a cafe, meeting our friends and just go home. The taliban say this is a western lifestyle. Maybe they say we are acting like europeans or american people. But i think its not true. We have the right to choose our life. A lot is being knocked out of afghan lives. At this popular bowling alley, we hear notjust worry about the taliban. The government is failing them too, even in promoting sports like this. Munir Ahmad Asafi is a national champion. Translation fewer people are coming here now. Before we used to gather about a0 people, we would divide into teams and hold competitions, but that doesnt happen any more. The changes over the past 20 years in afghanistan have brought new measures of freedom to many living in kabul. Its a life they want to hold onto and now fear they are losing. The departure of international forces is turning into the loss of so much more. For now, the walls keep rising to protect the most powerful, most privileged. The government under pressure to protect its own people. As the taliban make rapid gains beyond kabul, you feel the rising uncertainty on every street. Lyse doucet, Bbc News, kabul. In the united states, theres been a clash between Vaccine Makers and health officials over whether the public need a third vaccine jab, or booster shot. Last night, pfizer said it would seek approval for a third dose, amid concerns over the rapidly spreading Delta Variant. The centers for disease control, the Food And Drug administration, and the who have all weighed in, saying a third Jab Isnt needed or not right now. Pfizer has been developing a Booster Treatment as a way to strengthen antibodies which fade over time and guard against new, highly contagious versions of covid. We can now speak to dr john swartzberg, Professor Emeritus of The School Of Public Health and an expert on vaccines and infectious diseases at the university of california berkeley. Thank you for being with us. I guess the logical presumption is if one vaccine gives you a certain amount of protection, the second dose gives you a bit more . Surely a third dose gives you a bit more . You a bit more . Right, if a little bit you a bit more . Right, if a little bit is you a bit more . Right, if a little bit is good, you a bit more . Right, if a little bit is good, a you a bit more . Right, if a little bit is good, a lot you a bit more . Right, if Al Little Bit is good, a lot must be better. Of course that doesnt hold for a lot of things, particularly medicines. You know, Pfizers Idea that people need a third dose is curious. They didnt complement that with, they didnt release any data to support their argument, and frankly there is no data that i am aware of that says people need a third dose at this point. It is perfectly possible that months from now in the we may need a third dose, but right now there is just no evidence for that. I think the who, the cdc and the are all correct. Are all correct. What is involved are all correct. What is involved in are all correct. What is involved in the are all correct. What is i involved in the process . Are all correct. What is involved in the process . Well, the process involved in the process . Well, the process is involved in the process . Well, the process is really involved in the process . Well, the process is really quite the process is really quite robust. They all submit all of their data to the fda, the fda will massage it for a while and they will be a select committee thatis they will be a select committee that is not part of the fda but advises the fda that will then massage it further and will make a recommendation in almost always, but not always, the fda follows that select committees recommendation. And it goes to the cdc whether cdc will massage the data, they have another committee, independent of the cdc, that advises the cdc, they all do the same thing. They will ultimately give their blessing or not to the cdc. It is somewhat serpentine in how they are going to get there. This comes amid rising going to get there. This comes amid rising cases going to get there. This comes amid rising cases of going to get there. This comes amid rising cases of the going to get there. This comes amid rising cases of the Delta L amid rising cases of the Delta Variant causing concern here in the uk and also across large parts of asia. There are also variants of concern, of interest, not of concern. How important is it to update vaccines to keep up the pace with these variants . Vaccines to keep up the pace with these variants . Well, the aood with these variants . Well, the good news with these variants . Well, the good news is with these variants . Well, the good news is that with these variants . Well, the good news is that to with these variants . Well, the good news is that to date with these variants . Well, the | good news is that to date there is no variant that reliably or predictably will escape the vaccines, the immunity we get from vaccine. That is the good news. Even the Delta Variant, while it doesnt respond as well to Astrazeneca Orjohnson Johnson well to Astrazeneca Orjohnson Johnson here, it does respond adequately so that people are not winding up in hospital and dying from that which is the main thing you want from these vaccines. But going forward, you are touching on a very important point and that is that we have seen this virus evolve with new variant after new variant after new variant. The uk was battered by the Alpha Variant Injanuary the uk was battered by the Alpha Variant in january and the uk was battered by the Alpha Variant Injanuary and we got hit by it not as badly in the spring and now the uk is battered by the Delta Variant and now were getting the same phenomenon. We are always a few months behind the uk with these variants. But we need to get Herd Immunity in this planet, notjust in one or two countries, but on this planet, and we are going to see, continue to see Human Beings getting infected and producing these new variants. These variants may ultimately escape the immunity from vaccines. There is discussion about the doses but huge parts of the world, people havent even had their first dose yet. Their first dose yet. Yes, yes. There is their first dose yet. Yes, yes. There is an their first dose yet. Yes, yes. There is an irony their first dose yet. Yes, yes. There is an irony there, their first dose yet. Yes, yes. There is an irony there, isntl there is an irony there, isnt there, pfizertalking there is an irony there, isnt there, pfizer talking about giving people here a third dose and we have got so many billions of people not vaccinated at all. It has been saddening and it is a good argument, if there is that much access vaccine, perhaps we would be better off, all of us would be better off, all of us would be better off, all of us would be better off, if we used that vaccine to get more people vaccinated in other parts of the world. John swartzberg, professor the world. John swartzberg, Professor Emeritus the world. John swartzberg, Professor Emeritus at Professor Emeritus at university of california, berkeley, thank you very much, fascinating to talk to you. Thank you. This is Bbc News the headlines following the assassination of Haitis President and the unrest that followed the Countrys Senate nominates an interim successor. The taliban are rapidly retaking land across afghanistan as the us led mission withdraws the last of its troops. Residents of california are bracing for a weekend of record setting temperatures as heat continues to build on the west coast. The us national Weather Service has issued an excessive Heat Alert, with meteorologists warning that some of southern californias inland areas could reach temperatures of 49 celsius that is 120 farenheit. Earlier i spoke to Eric Schoening and asked him what things were like at the moment. This is a long duration and widespread heatwave across much of the Western Us which has already begun, it is really going to peak this weekend, we are going to see really hot temperatures and really big heat impacts, potential Health Impacts for the population through the weekend and into the beginning of next week. And this comes off the back of periods of drought in california, Fire Concerns talk us through how those play out in this situation . Absolutely, so much of the western united states is in an extreme drought, so it has been going on for quite a while, and that creates a lot of concerns, Water Supply concerns in many places, we also have Fire Concerns in many places, where a lot of our fuels for potential wildfires are quite dry. And then you add on the heat and that dries out those potential Wildfire Fuels even more, and also as i mentioned, potentially leads to a lot of Health Concerns across the population. How long are you expecting this to go on for . It started ealier this week, around wednesday is when a lot of the heat really started building across south eastern california, and a lot of places across the united States West will see the worst of the heat this weekend, saturday and sunday, potentially going into monday in a lot of places, and then we will finally get some relief tuesday and wednesday as we get a little bit of cooling across the region. And the cities and states that are affected, are they prepared for these kinds of temperatures . You know, its something that a lot of these states do see in the summer, and thankfully in this case we were able to get the warning out quite early, so a lot of the cities and states have been setting up things like cooling centres, and getting a lot of resources out to their people but at the same time, we are seeing temperatures that are meeting or sometimes exceeding all time record highs, so while this is something that a lot of these areas are ready for, at the same time these are temperatures that, you know, even people who have lived there a long time have never seen before. You mentioned the record high daytime temperatures, but these temperatures are staying high at nighttime as well, arent they . Thats right, they are staying quite warm at night, there are a lot of places that will be staying in the 70s and 80s degrees fahrenheit, so something like 25 celsius or even 30 celsius overnight in some places, so that is something that is really concerning, it really adds to the Health Concerns when people cannot cool off overnight. And in terms of trends, is this the kind of Weather Event you expect to see more of, year on year . Yes, as the globe continues to warm, studies have shown we will see more and more extreme Weather Events like this. While you cant necessarily tie one particular event to Climate Change very easily, we will continue to see more see more and more of these extreme Weather Events across the globe.

Moscows been criticised for its alleged role in cyber attacks its Annexation Of Crimea and its support of the syrian government. The latest Sticking Point is a little less momentous, but a lot more bubbly the cosmonaut said it was emotion and the guests enjoyed themselves and russian fashion. Even in the days of the Soviet Union and it may have been resist dismissed as a symbol of the decadent west, russian still love champagne. So much so they have become a little possessive of it. Insisting that within their borders, they will decide what is and isnt the real thing. A new law requires foreign companies, including those in france, to label their bottles as sparkling wine, but there is no such rule for the russian version, known as shampanskoye. This has left something of a sour taste in the mouth for french ministers, wanting to show their support for a world renowned industry.

The Sprint Finish took his tally to sa level with belgiums eddy merckx, whos held the record since 1975. Cavendish won his first Tour Stage 13 years ago and is now aiming to break the record before this Years Race concludes in paris in nine days time. His former Teammate Mark Renshaw told me what it meant to cavendish and sport in general. This will mean everything to Mark Cavendish. Eddy merckx is a man he respected very highly, as does everyone in cycling, so to draw equal with his record, it is a phenomenal effort, and i think it will take a little bit for this to sink in with Mark Cavendish because it was a record he probably never thought he would achieve, to equal eddy, but this year, look, some things have fallen his way, he has had a little bit of luck, and now we are in the race, he has got the form and the legs to be the best in the peloton, hence winning these four stages and drawing level with eddy merckx. And as you say this is remarkable, especially because several years ago he said he thought his career was all but over . Look, i retired back in 2019 and at that point i wasnt sure whether we would see Cavendish Return to the Tour De France and winning stages. He had a great year last year when his team, but this season, changing to deceuninckouickstep, a team where we both raced with in the past, under the guardianship of patrick lefevre, he has flourished, he has found his form once again, and that Killer Instinct that makes him the best sprinter in the peloton. It is great to see him back on top of the game and it really has to be said that he is in the best team for sprinting. With those guys pulling together and working for Mark Cavendish, it does make him once again the best sprinter in the peloton. Cycling is one of these funny ones where you are on the bike by yourself, but you are also part of a bigger team. What is Mark Cavendish like as a teammate, as a sportsman . Look, cycling is a very different sport to most other common sports, it is a Team Sport where individuals win, is the best way to describe it. You need a team to win, without them you dont have any chance to be successful. And Mark Cavendish is one of the best team players in the sport of cycling. If you are loyal to him, if you give him 110 he will return to you any time he gets the chance. And as a Team Leader he is one of the best Team Leaders i have worked with, obviously, that is what makes him super successful, the way he can lift riders, lift teams to chase goals and numerous wins. Some riders would be happy with one win in the Tour De France but Mark Cavendish is always striving for more. Before we go, england will play italy in the euro 2020 final on sunday. Many here in the uk will be glued to their seats. But they dont need to be, because we think we know whos going to win thats because of a group of so called � Mystic Meerkats at London Zoo who have picked england as the winner a Zookeeper Put flags in their enclosure one for each country. The first to come down would be victorious. The meerkats are the latest in a long line of animals with Predictive Powers a german octopus picked winners during the 2010 world cup. Lets see if the Meerkats Prediction is correct. You can reach me on twitter im richpreston. From me and the team, we will see you next time. Hello there. Its looking unsettled this weekend as well, but its not going to be raining all the time everywhere. There will be some places staying dry, but the general theme this weekend is for sunny spells and for scattered showers to develop. Again, these will be heavy and thundery, and slow moving as winds will be light. If you look at the Pressure Chart for saturday, weve got this Weather Front across the south, bringing an area of more persistent rain to southern counties. It will continue its Journey Eastwards through the morning through the channel islands, southern and south eastern counties of england, then clear away in the afternoon. Elsewhere, after a dry start, well see those showers developing a little bit further westwards this time, affecting wales, west midlands, North West England and scotland. Again, it will be heavy, slow moving torrential downpours which could lead to localised flooding. Those temperatures range from 19 21 degrees. Now, those showers will fade away during saturday evening, and then, overnight, most places will be dry, but rain will start to push into the far west later on, those temperatures in double figures. Its going to be another mild and Muggy Night for most of us. Now, for sunday, a new area of low pressure starts to push in off the atlantic, affecting northern and western areas. It looks like some eastern parts may stay dry altogether with some hazy spells of sunshine. So, most of the heavy showers on sunday will be across more northern parts of the uk, but wales, northern ireland, the southwest of england will start to see areas of more persistent Rain Moving in. In the east, with that sunshine, we could see 22 23 celsius, and again, its going to feel quite humid. So, for wimbledon this weekend, saturday, the early rain will clear away to leave something a bit drier into the afternoon. Sunday, mainly dry, but i still Cant Rule out the Odd Shower there. And for wembley on sunday, certainly its a dry start, but into the evening, we start to see some of that rain in the west pushing its way eastwards. Thats because this area of low pressure will be working its way southwards and eastwards across the country. By monday, this is the Position Itll be in. Its going to bring a very unsettled day. Most northern and western areas will see sunny spells, some heavy showers. Its england and wales which will see the cloudiest skies and areas of heavy, maybe even thundery rain affecting central and southern areas, which could lead to some issues. The temperatures not quite as high 19 20 celsius will be the high. The heavy, thundery showers clearing away from the South And East on tuesday and wednesday. By the mid latter part of the week, High Pressure wants to build in, so itll start turning sunnier, drier, and warmer.
