Is the Counteroffensive Intensi Inc . ~ ,. , intensifying . Well, it has been a bus da , intensifying . Well, it has been a busy day, sophie. Intensifying . Well, it has been a busy day, sophie. From intensifying . Well, it has been a | busy day, sophie. From ukraines point of view, a successful one. It has managed to hit the headquarters of russias Black Sea Fleet in the Crimean Peninsula with a missile. We know there is damage to the building. We are not sure how much. One ukrainian spokesman has said on social media, we wanted a bigger hole. But undoubtedly, ukraine could hardly have picked a more symbolic target. Its a headline grabbing attack, it is a showy attack. It is not the first time that ukraine has struck at Russian Military and the structure in premier. As ukraine faces into the second winter of war, we know it is suffering heavy losses on the battlefield, although the numbers are a closely guarded military secrets. We have been given access to a hospital in the south east, a major regional centre, which is one of the main places where casualties are sent directly from the battlefield. Now, doctors there have told us that since russias full scale invasion in february of 2022, they have treated 20,000 wounded soldiers, and many of them are amputees. Sirens under a blanket of darkness, the wounded are brought in. On arrival, each one is numbered. Each one a husband, a father or a son. This is the pain of a generation. Staff here treat 50 to 100 new casualties every day. Another badly wounded soldier has just been brought in. Hes in his 20s and one of his legs has already been amputated. This is where you can see the cost of the war. The cost for soldiers, the cost for ukraine. And theres no let up the casualties keep coming. Oleksiy is 38 and days before lost both of his legs. Translation the inuries are very severe. H im very glad that oleksiy survived. This was caused by a mine explosion. Unfortunately, his friends are no longer alive. War is frightening, says oleksiy. Only a fool wouldnt be scared. What more can i say . Bullets whistle, mines explode. More than 20,000 injured soldiers have passed through these doors in europes newest war, a Conveyor Belt of broken bodies. Even when the fighting is over, for many, the battle will last a lifetime.

Here, the Prime Minister is considering a major shake up of the a level system in england. Our Political Correspondent nick eardley is in westminster, what is rishi sunak looking at doing . Sophie, rishi sunak has promised to deliver answers to what he sees as some of the big, long term questions the uk is facing. Earlier this week we had the controversial announcements on net to zero. Next, it could be education. Because the Prime Minister, in downing street, are weighing up some pretty significant reforms of the a level system in england, as it is at the moment. One of the options that is being considered by number 10 is replacing a levels with a so called british baccalaureate. It would involve people studying more subjects than the three four they do at a level at the moment, it would involve everybody who takes them studying english and maths to the age of 18. We know that rishi sunak is a very keen on more people studying maths until 18. I should point out that none of this is confirmed yet, it is being weighed up confirmed yet, it is being weighed up a number10. We confirmed yet, it is being weighed up a number 10. We told that no Firm Decisions have been made yet. But if it happens, what is certain is that it happens, what is certain is that it will be controversial. Some in the Education Sector think that it would be too expensive. That the money could be better spent on retaining teachers or on rebuilding infrastructure. Labour have said that it infrastructure. Labour have said thatitis infrastructure. Labour have said that it is simply an undeliverable gimmick. But its possible that we will hear more details from the Prime Minister in the next two weeks or so. Always remember the political context to stories like this. Sophie, a Conservative Party that is far behind labour in the polls, trying very hard to find something that will capture the political imagination in the run up to the election. Police have found a large quantity of the highly potent painkillerfentanyl, in a New York City nursery where a boy died from exposure to the drug. The Authorities Say they discovered enough fentanyl and other drugs hidden in the Daycare Centre to kill half a million people. Fentanyl is 50 times more powerful than heroin and has been blamed for a rise in drug deaths in the united states. From new york, John Sudworth reports. A small memorial at the door of the Daycare Centre marks a tragedy that new york prosecutors say has shocked the conscience of a city. One year old Nicholas Domenici died and three other children were hospitalised as the result of exposure to the deadly synthetic opioid fentanyl, that police say was kept hidden in huge quantities close to the mats in the nursery on which the children played and slept. A place meant to safeguard that ultimate act of trust, the care of children, turned into a crime scene and a family left devastated. I love him, nicholas father says. The owner of the nursery, 36 year old grei mendez, has been charged with murder, along with a relative, Carlisto Acevedo brito. Both are said to claim no knowledge of the drugs. But the police, who are still looking for one other person, say all three were part of a conspiracy. Is alleged in the complaint, before Emergency Personnel arrived at the daycare, before they arrived, mendez and a Co Conspirator try to cover up what happened. And all of that happened while the children, the babies, were suffering from the effects of fenta nyl babies, were suffering from the effects of fentanyl poisoning, and in desperate need of help. Fentanyl is a painkiller 50 times more powerful than heroin and 100 times more powerful than morphine, and has been blamed for a rise in us drug deaths. In 2010, fewer than 40,000 people died from a Drug Overdose across the country, with less than 10 fentanyl related. By 2021, the number of deaths had risen to 100,000, with an estimated 66 of them caused by fentanyl. What the statistics dont reveal is the individual human suffering, something new york is now confronting in stark reality. I spoke with the dad, you know, of the baby we lost. It rips your heart out. A death that ought to be incomprehensible is instead the latest grim milestone in a drugs epidemic out of control. Prosecutors say what happened here is inexcusable and unconscionable. New yorks mayor, eric adams, as well as speaking emotionally about his interactions with the parents of Nicholas Dominici and the other injured children, says it should serve as a wake up call to anyone, anywhere, with children, who keeps opioids in their home. An eight Year Old Girl has become the first child in the uk to receive a Kidney Transplant that means she does not have to take long term drugs to stop her rejecting the organ. The girl received both stem cells and a Kidney Transplant from her mother, which meant her body accepted the new organ. Our medical editor fergus walsh joins us now. Fergus, explain the significance. Well, sophie, first and foremost, this is fantastic news for eight year old aditi here and her family. She is the first child in the uk to benefit from this Ground Breaking new transplantation method. Aditis health has been transformed, thanks to her mum and a team at Great Ormond Street Hospital in london. She has an extremely rare genetic condition which had weakened her Immune System and meant her kidneys were failing. Doctors came up with a radical new approach, which involved not one but two transplants. The medical team began by removing stem cells from a aditis mum. These were used for a bone Marrow Transplant which rebuilt and re programmed aditis Immune System. Six months later, she had a Kidney Transplant, again donated by her mother, and her reprogrammed Immune System accepted the organ as her own. Her Immune Deficiency had to be corrected by having mums bone marrow first, and because aditi was able to engraft and accept her mums bone marrow, that therefore meant that her body could then see her mums kidney, when it was transplanted, as being part of her. Transplant patients usually have to take Immunosuppression Drugs for life to prevent their body rejecting a new organ. But this makes them more vulnerable to infections, and there are other long term side effects. But because aditis Immune System matched her mothers, she was able to come off these anti rejection drugs just a month after getting her new kidney. Her parents say she is back at school and doing well. Ifeel so happy, actually, yes. Ive given the blood cells and the kidney. So happy, yes, of course. I feel perfectly ok, yes. Im so proud of her. And she is amazing. She is doing very fine, each and every day. And most of the support, i would say, is from her side. Because if she was someone who was bogged down by the procedures, or what she listens to on the ward, it could have been much more difficult for us. On the other hand, she was the one who was actually more outgoing. The procedure is unlikely to be widely used, as the initial bone Marrow Transplant involves chemo and radiotherapy which come with increased risks to the patient. But for aditi it has been life saving. Mortgage brokers are saying rates should begin to fall following the Bank Of Englands decision to keep Interest Rates on hold yesterday. Good news for many homeowners but itll make little difference to the hundreds of thousands of people who own flats with Flammable Cladding and building safety defects discovered in the wake of the Grenfell Tower fire. Because of the problems with their buildings, they are unable to shop around for the best Mortgage Deals and must stick with their existing lender, as phil hendry explains. Its really upsetting. This is my first home. I wanted it to be fantastic. Dans dream home has turned into a nightmare. His Mortgage Payments have doubled for a flat with a leaking roof and other fire safety and building defects. Hes paying 8. 5 interest on his loan for the privilege. This has been such a traumatic experience. I dont sleep. Im angry all the time. Theres physical symptoms. Since i spoke to dan, his psoriasis has flared up with the stress, and its little wonder. It looks like a solid brick wall. But when i lean on it, the whole thing, including the roof, moves. Its not the only wall that moves. Interest rates may have stopped rising, but the defects mean he cant get a Better Mortgage deal. Weve been in a legal battle which has wiped out all of the savings i had. And so to have to pay an extra £500 a month, roughly what it is now, im not really sure how im going to continue to cover it. His desperation, clear to see. He blames those who make and enforce Building Regulations for letting him down. There is some good news for dan. I contacted his mortgage lender, santander, and theyve agreed to offer him a lower Interest Rate. But hes just one of hundreds of thousands of people trapped by the cladding and building safety crisis who cant shop around for the best Mortgage Deals. Its so frustrating. You have no choice. You have no freedoms. Lisas two bed flat has a small amount of Flammable Cladding, the same as was found on grenfell. But because her building is lowrise, its not eligible for Government Funding to replace it. Im in this situation through no fault of my own and not out of choice. So its, its really, really galling. Lisa is on her lenders cheapest rate, in line with government advice for flats with cladding. Interest rate rises may have paused for now, but its already meant sacrifices. Our Mortgage Repayments have gone up by about £500 a month. So weve had to get rid of the car, make other savings wherever we can. Its been dreadful. Its ruining me. The Bank Of England putting a hold on Interest Rate rises has come too late for roy. Hes just handed back the keys to the flat he bought in manchester for the bank to sell. Its Flammable Cladding has been replaced, but its put buyers off. I have had to see my gp. They have referred me for kind of talking therapies. It has helped me to kind of rationalise. | luckily, im not a drinker or anything like that. Roy now lives in a house he bought when he became a father. But until the bank sells his formerflat, he remains liable for the mortgage. Hes among the first, but probably not the last, to hand back keys for flats affected by the cladding crisis. Phil hendry, bbc news. The time is 6 16. Our top story this evening ukraine launches a Missile Strike on the headquarters of russias Black Sea Fleet in crimea. And coming up we speak to this youtube star about why hes stepping back from the spotlight. Coming up on bbc news. After the us make it a clean sweep on the first morning at the solheim cup, europe have spent the afternoon four balls in spain attempting to fight back. A seven year mission into space to study the asteroid known as the most dangerous space rock in the solar system should reach a dramatic conclusion on sunday. A capsule that has been to scoop up a sample from its surface is due to return to earth finally, landing in a remote part of the us state of utah. Science editor Rebecca Morelle is there for us now. How are the nasa team there feeling . Yes, the clock really is ticking for the team here at the Military Base in utah. The landing is less than 48 hours away. The helicopters are ready in the hangar, getting ready to go out and bring the capsule back. Then the painstakingly slow process of opening it up to reveal what is inside will begin. Now, the lead scientist has said they are ready, and he is 99 certain everything will go to plan, but it is just that 1 that is keeping him up is just that 1 that is keeping him up at night. Is just that 1 that is keeping him up at night. Asteroid bennu, A Boulder Strewn rock hurtling through space, the target of a seven year nasa mission. After travelling billions of miles, captured on camera the moment the Osiris Rex Spacecraft collected its sample in a smash and grab lasting just five seconds. These bits of bennu were stowed in a capsule. Now theyre heading back to earth. Were looking at material that existed before our planet did. In fact, some of it may have been from even before the solar system formed. So were looking at the beginning of our story. How did our solar system form, how did asteroids come together . And did asteroids like bennu literally make the earth a habitable world . The capsules landing site is a vast wilderness, a Military Base in the utah desert. Asteroid bennu is 500 metres in size, taller than the empire state building. Its shaped like a spinning top, bulging at its middle. And although it looks solid, its actually a pile of rubble loosely held together with a little bit of gravity. But bennu tops the list of nasas most dangerous space rocks. Its orbit around the sun can bring it close to the earth sometimes dangerously close. And the chance of a collision is one in 1,750. Thats like Tossing A Coin and getting 11 heads in a row. And the 24th Of September 2182 is the date its most likely to hit. Its a very low likelihood of hitting the earth, and thats more than 100 years in the future. But its really important to characterise its orbit, to understand its physical properties, so that if we do need to do anything to deflect Asteroid Bennu or another asteroid in the future, we are prepared and have all of the information that we can. The return wont be easy. The capsule will speed through the earths atmosphere at more than 27,000mph before descending down to the ground, slowed by parachutes. The nasa team has been practising in the desert, working out the best way to recover the craft after it comes down. Its vital to keep the extraterrestrial material inside free from contamination. All eyes are now on this patch of utah
