hit by inflation. taiwan accuses china of practising for an invasion of its island after beijing expressed fury over us house speaker, nancy pelosi's visit to taipei. hello and welcome to bbc news. air raid sirens and explosions have been heard injerusalem as a conflict between israel and the palestinian militant group islamichhad escalates. it follows intense israeli air strikes in gaza which killed a second senior leader of the islamichhad group. khaled mansour was considered the most important man in the armed wing of the organisation. these are images of the latest air strikes. a total of at least 29 palestinians — some of them children —

are now reported to have been killed in this latest outbreak of violence. earlier i spoke to our middle east correspondent, yolande knell, to get the latest on what's been happening this morning. earlier i heard distant blasts as the rockets were fired by palestinians in the gaza strip toward jerusalem, the first time that has happened since the full—scale conflict in gaza last may. they were intercepted by israel's missile defence system, but this was important symbolically. it happened at a time, it's a jewish holiday there are nationalists being allowed to visit the disputed holy site injerusalem known as temple mount for dues. islamichhad also had been promising

to rain down rockets, in its words, on the heads of israelis after it lost a second commander in gaza overnight, he was killed in an israeli air strike in the south. this man, khaled mansour, is supposed to be the most senior person that had been left from the islamichhad leadership on the ground in gaza, a real serious blow to the organisation. 0n the military side of this, israel will also claim these are targeted surgical strikes, and then you will hear palestinian voices saying, actually this area is so densely populated it is almost impossible to avoid so—called collateral damage, ie, innocent lives being lost. that is exactly correct. we hear that every time there is a conflict in gaza, the death toll is continuing to rise, 29 people killed is the latest, including six children since the start of the israeli military operation targeting

islamichhad began on friday. in addition to all that is going on israel has been putting out a video from its military showing what it says is a misfired militant rocket in gaza, there is a lot of speculation that this is what caused the death of several people including children close to a mosque in the north of the gaza strip overnight. it seems a number of islamichhad's rockets, the israeli military says about 20%, are misfiring, as they are launched from gaza. so some of them do land within the gaza strip. at the same time, on the humanitarian issue, obviously things are very scary for israelis and palestinians, israelis particularly in the south of the country with air raid sirens going off but there is a humanitarian situation in gaza that

is really worsening, even the israeli military when you talk to them for briefings, are very aware of this, and they say it is not safe to allow convoys to enter gaza at the moment. the main crossing with the gaza strip from israel have been closed for the past week and that has meant fuel cannot go in for the sole power station, that has had to close down, and if you imagine, there are about 200 people injured in the violence going on, hospitals say they are unable to cope. to ukraine — where another convoy of ships has set sail from the country's black sea ports carrying grain and sunflower oil. four vessels set off from 0desa and chornomorsk via a safe maritime corridor, heading for turkey where they'll be inspected as part of a deal reached with russia and the un. the agreement is aimed at freeing 20 million tonnes of grain and other essential supplies which have been blocked in ukraine since the russian invasion — causing worldwide shortages.

0ur correspondent hugo bachega is in kyiv. it seems another sign this deal is working, four more ships departed the ports of chornomorsk and 0desa in the south of ukraine, they are going through that safe maritime corridor created because the black sea is infested with mines and once they get to turkey they will be inspected by a team of russian and ukrainian officials and turkey and the united nations, which helped broker the deal. two of those ships will stay in turkey and the other two will go to italy and china and another vessel has been authorised to come to ukraine to be loaded with grain. it's a positive development, we've heard from the ukrainian infrastructure minister saying they expect to be able to export up to 3 million tonnes of grain every month. to give a sense of perspective, there are 20 million tonnes of grain stuck here in ukraine.

it is vital for ukraine for this deal to be working and to be a success, not only because it will ease the global food crisis but also fundamental for ukraine to be receiving some foreign currency. indeed. if we go right back to the beginning, when this agreement was first signed, russia did attack targets in and around the port of 0desa and a lot of people were very pessimistic that this would get off the ground. is there still that level of trust and confidence between the two sides that this deal will hold? we heard from president zelensky in his evening address, saying it is a positive development that these ships can leave ukraine and others are coming to be loaded with grain but he said there are some security concerns and he says he needs to see if russia is going to follow

the terms of this deal. so far we're seeing there have not been any kind of incident so far, so good for this deal. here, in the uk, conservative leadership candidate liz truss will reverse the planned increase in national insurance contributions within weeks of becoming prime minister, according to her campaign team. arguments between ms truss and former chancellor rishi sunak over how to handle the economy and the cost of living crisis have been central to the campaign. 0ur political correspondent jonathan blake has the latest. the foreign secretary pledged at the start of this campaign to reverse the rise national insurance payments, it was brought in while she worked in government and her rival rishi sunak was the chancellor. it was expected that would happen in april, at the start of the uk tax year, but she said she would be able to and would do it within weeks of taking office, promising to hit the ground running with an emergency budget. one of the measures

within that would be this. not a new policy but in terms of the timescale, pledging to go ahead with this faster than she initially had done. as to what difference it will make, rishi sunak�*s campaign have hit back and said reversing the tax rise will not make too much of a difference depending on people's earnings, slightly less than £200 a year for a typical earner. they argue because of changes he made as chancellor to the threshold at which people start paying national insurance actually the people who are needing help them most in this coming winter as energy bills rise, they will not get much out of this at all. and an intervention by a former prime minister this morning? talking of an emergency budget, that is what former labour prime minister gordon brown has said is needed and he called for collaboration between borisjohnson and the two candidates to replace him, to agree on a date for that to happen

as soon as the winning contender takes office. he has warned of a financial time bomb threatening to explode and push millions over the edge. as that predicted rise in energy bills goes ahead in october and again at the start of next year. he's been explaining that more this morning. talking about tax cuts that will not benefit the people who are really poor right throughout this campaign and only because the pressure is growing are they talking about the changes that will happen immediately but it is the urgency i feel is missing about the needs of people who are... children have been going to school ill—clad and hungry and we've got families having to choose between feeding their meters and feeding themselves. we see churches discussing how they can run heat hubs during the winter months because they know people cannot afford to heat their homes. the best we can hope is through blankets or duvets

or sleeping bags hot water bottles or duvets they can heat themselves. the crisis will affect 15 million households, the severity of these households could be {30—40 a week short of what is needed to pay their bills and we are talking about the social consequences — more children in care and more homelessness and more mental illness and more suffering, and this unbearable burden has got to be taken off the shoulders of the people who are least able to fend for themselves. gordon brown talking about the direct impact of the cost of living crisis on so many people, and he is one of many voices suggesting the way this leadership contest has played out has focused too much on ideological arguments and ignoring the real impact that people are facing and the financial hardship so many are struggling with in the uk at the moment,

and calling for the candidates to say more about what exactly they would do. let's go to the growing tensions between china and taiwan now — and china's military exercises continued on sunday morning in close proximity to taiwan, albeit at a lower intensity than on previous days. taiwan has accused china of practising for an invasion of the island, while the us has accused beijing of using military drills to change the status quo. 0ur correspondent stephen mcdonell is in beijing. hardliners in the operational and is on the chinese party in beijing must be pretty happy we at nancy pelosi's visit has left them. more extreme military measures have now entered what we might consider as acceptable in terms of how the mainland deals with thailand. are we going to see every year now beijing ordering the pla to fire missiles over taiwanese

territory —— how the mainland deals with taiwan. as the pla prepares for what some would see as inevitable attack on taiwan as a means of trying to reunify it with the mainland. there have been significant short—term problems, for example, commercial shipping has been disrupted, that is a very busy shipping lane, the taiwan strait, that's been significantly disrupted, as have commercialflights. taiwan's significantly disrupted, as have commercial flights. taiwan's economy has been hurt and apart from all these short—term impacts, beijing and washington are now not cooperating with one another on all this whole series of areas where they were able to get some work done, so despite the tensions between the us and china, for

example, on cross—border crime there was an operation, that has now been put on hold. including work on narcotics. no more senior meetings between the military in the us and china. safety at sea, there have been work done with the navy is in terms of maritime safety between the china and the us and, crucially, china and the us and, crucially, china cancelled talks in terms of climate change amelioration. this is bad news for the rest of the world because it means the world's two biggest carbon emitters are now not going to be talking to one another, looking for areas of cooperation at this quite crucial time. so where to from here? it is hard to see all these areas previous corporation can be linked up again, if i can put it that way. at the moment there seems

to be increased tension and i suppose there would be some in washington and beijing wondering how this could all be clawed back but at the moment there is no sign that either beijing or washington wants to back down and we could be had into a period of quite some tensions into a period of quite some tensions in this part of the world. in cuba, a body's been recovered from the site of a huge industrial fire that's been raging since friday — when a fuel depot was struck by lightning. this is the moment of storage facility exploded. more than 120 people have been injured, and i7 firefighters who were tackling the blaze are currently missing. cuba has asked the us — and neighbouring countries to help in efforts currently under way in the coastal city of matansas. 0ur cuba correspondent will grant has the details. we know that at least 17 firefighters are missing, which is obviously a horrific situation for cubans, for the island more generally,

and this couldn't come at a worse time for the nation, in many ways, in the grip as it is of a nationwide electricity, rolling electricity blackout. havana, the capital, has recently been told it is going to have to start experiencing blackouts as they try to move elements of the electricity grid to other parts of the island that need it, so, really, it comes at a terrible, terrible time to have a fuel depot on fire to such an extent that they can't bring it under control and have appealed to neighbours like mexico and indeed the ideologicalfoe of the united states, both of whom have indicated a willingness to help. i mean, the very bottom line is that they want to get the fire under control immediately, as soon as possible. so, if you can send firefighters, support, you know, equipment, that is what they are looking for in the short term. beyond that, there will be other elements that they will need to rebuild the site and make it safe again. but in the short term,

i think the emphasis is on simply bringing this blaze under control. and this tells us a lot about where cuba is at the moment, that this blaze is so out of control, talks to the extent of the crumbling infrastructure on the island, of course worsened by the decades—long us economic embargo, something that the united states has been at pains to point out that, you know, doesn't prevent them from helping in an emergency situation like this one. in mexico, ten miners are still trapped in a coal mine that collapsed and flooded on wednesday. hundreds of rescuers are now involved in the efforts, including several divers. the mine is in the town of sabinas in northern mexico, and in a region that is no stranger to incidents like this. the bbc�*s azadeh moshiri has this report. mexico's president says efforts to rescue ten workers trapped in a coal

mine have reached a crucial point. they have been underground since wednesday after the excavation caused a tunnel wall to cave in and triggered floods. rescuers are working on pumping out the water to allow divers to enter. translation: the good news is the pump which has much more capacity in emptying one of the wales, this will hopefully deliver and very positive result compared to what was achieved throughout the night. five of the workers managed to escape within the first 2a hours but since then no survivors have been found. so the families have been waiting and hoping for good news. sleeping through the night in cots, blankets, plastic chairs and whatever else they could find. translation: we whatever else they could find. translation:— whatever else they could find. translation: ~ ., , ., , translation: we are still hoping that they are _ translation: we are still hoping that they are in _ translation: we are still hoping that they are in a _ translation: we are still hoping that they are in a higher _ translation: we are still hoping that they are in a higher part - that they are in a higher part although it is too much water, the well was up to the top but we trust

in god. the incident has brought back memories of the tragedy in 2006 when an explosion in a local mine killed 65 people. mexico's president has said investigations into who is responsible at this time we'll have to wait. the focus right now is on saving lives. let's take a look at some of the other stories making the news... police in brazil have arrested five people for illegal fishing in an indigenous reservation — the same area where an indigenous expert — and a british journalist — were killed two months ago. bruno pereira and the journalist, dom phillips, were shot dead as they investigated the involvement of organised crime in commercialfishing. firefighters in spain are battling six wildfires in the north west of the country. 700 people have been evacuated from the area around boiro. no casualties have been reported so far. there have been 366 wildfires

in spain so far this year — fuelled by scorching temperatures and a severe drought. emergency workers are searching for stranded motorists inside california's death valley national park after flash flooding trapped nearly 1,000 people inside the park and forced its temporary closure. the flooding was triggered by a near—record downpour over one of the hottest, driest spots on earth. here in the uk — an 11—year—old girl has died after getting into difficulty at a water park in berkshire. members of the public searched a lake at liquid leisure in datchet saturday afternoon before she was found by emergency services. thames valley police say they are treating her death as unexplained. in italy, archaeologists have unearthed four new rooms in a house in pompeii — offering more insights into life in the ancient city. the discovery happened in what was once one of the doomed city's largest neighbourhoods, before it was hit by

a volcanic eruption in 79 ad. about two—thirds of the city have now been uncovered — and it remains one of italy's most popular tourist attractions. tom brada reports. an ancient city frozen in time by a monstrous eruption almost 2,000 years ago. still—vibrant ceramics, a wooden dish cabinet, fragments of an extremely tired bed — just some of the treasures unearthed by archaeologist at pompeii, offering a glimpse of what life was like for ordinary roman citizens before the town was pummelled by mount vesuvius in 79 ad. these items were all found in four newly—excavated rooms, first discovered at a property in 2018. in one room, there's a cupboard that had stayed open for the best part of two millennia. translation: here, you can see the cabinet with the wooden - parts of the doors. inside the cabinet,

there were shelves — and what we see is the shelf that collapsed when the volcano exploded. inside, we found glass objects like these bottles, but also ceramics like these vases that we're gradually discovering. in another room, there's a table still holding its original ornaments. and in another, even a bed with parts of the bed frame still intact and traces of fabric from the original inhabita nts' pillow. a lot of this excavation work is being carried out during peak tourist season. translation: we have about 12,000 people coming in each day, _ sometimes up to 15,000. with due care, we are able to manage the situation safely. it's little surprise that pompeii continues to attract visitors in such numbers. thousands of years on from its infamous devastation, its ancient ruins continue to offer fresh insight into the lives of the people who once called it home. tom brada, bbc news. it's a disease that's been around

for decades and now researchers in southampton think they've found a new vaccine against whooping cough. the next step is to test whether it's effective — but hundreds of volunteers are needed to take part in the trial. alastair fee has been to meet some who've already signed up. in three months�* time, georgia will be deliberately infected with whooping cough. i have some friends that have done clinical trials that said just give it a go, it's a bit of extra cash. it's most likely financial, but like if this is a way that i can help out in the medical sector, then i'm happy to just do that. she graduated last year, and the £3700 compensation has attracted her to a potentially life changing study for people all over the world. it's not that much work, and it's just coming in for 4—6 months. it's pretty easy. this southhampton testing a new type of vaccine. it's delivered by a nasal spray — the old vaccines were injected. the idea of this vaccine is that it improves your immune response

in your nose, so the place where we know that whooping cough gets in, and because it improves the immune response there, it should protect against what we call colonisation, in other words, carrying whooping cough bacteria without having symptoms. tony here is suffering _ from the after—effects of whooping cough, and he is about to become the subject| of a new experimental short—cut cure. - before vaccines, whooping cough brought severe illness and death in young children and babies. it's estimated that it still kills 160,000 people worldwide, many of them children. it's widely felt that the current vaccine is becoming less effective and can be improved upon. we know there was a relatively big outbreak of whooping cough in the uk in about 2012, but we have gradually seen an increase in numbers since that time, and we are trying to pre—empt any further increase that we might see. we know that globally there has been an increase in other parts of the world as well, and it does seem to be linked

to changes to the vaccine, which is effective for a period of time, but perhaps is wearing off more quickly. all patients first need to be screened to see if they are healthy enough to take part. scott is keen to support new vaccines, but also hopes the compensation will help him get on the property ladder. we have been trying to save for a few years. with housing prices climbing then of course we have to save more, so while we are at an ok point, this is a nice sort of chunk of change to have on top of that deposit money. while around 60 people will take part, several hundred are needed to see if they are eligible. many more people are being urged to come forward. all participants will have to attend several appointments and also stay in a hotel for 16 days where they will be carefully monitored. the trial will run until next april. it's hoped the results will make a big difference to the number of people who suffer worldwide. alastair fee, bbc news.

that's it from me. this is bbc news. goodbye. hello. we will be talking heatwave conditions again as we go through this week. over the next few days temperatures rise under largely sunny conditions, some cloud and rain particularly in the north and west of scotland, that is running around the high pressure that will build across the country through this week, and with ground dry and sunshine overhead temperatures will continue rising. those weather fronts to the northern edge bring some rain in western scotland at the moment, on and off this afternoon. much more sunshine in northern ireland and sunny spells in eastern scotland, some cloud, cloud and northern england, temperatures rising computer yesterday.

the south—east corner. high pressure hanging on, moving further east through the week, temperatures building, maybe some south—easterly winds bringing more humidity from the near continent but overall across england and wales we will see heatwave conditions quite widely by the middle of the week. temperatures widely into 30s. abergavenny and london into the mid—30s at times and even scotland and northern ireland where we've seen cloudy and wet weather of late, temperatures will reach the mid 20s. see you again soon.
