welcome home! applause and cheering. a triumphant return home for team gb after the olympics, as diver tom daley bows out. it's always hard when you say goodbye to your sport. so i just, yeah... lots of things to process but, you know, i think it is the right time. and remarkable news from mars, with new data suggesting there's liquid water, in its outer crust. stay with us here on bbc news for continuing coverage and analysis from our team of correspondents in the uk and around the world.

good evening. the ukrainian army claims it now controls 1,000 square kilometres of russian territory, after launching its surprise offensive across the border. thousands of people have had to be evacuated from russian towns and cities. state television says, so far, 11,000 people have been moved from belgorod, as ukraine continues its advance into the nearby kursk region, with the local governor saying in all more than 120,000 people have left their homes. in kursk ukrainian forces, shown here in yellow, have been operating up to 20 miles inside russia. kyiv�*s plan seems to be to draw russian forces away from the front line in ukraine, shown here in red, where moscow has been making slow but steady gains. today, president putin vowed to kick ukraine out of russia. 0ur russia editor steve rosenberg reports. a music video from the russian military, allegedly showing it targeting ukrainian troops who'd

crossed the border. it's presented like a blockbuster. in reality, this is a huge problem for russia. the governor of russia's kursk region put it in figures. he told vladimir putin that ukrainian soldiers had seized 28 settlements in his region. the kremlin leader cut him off. "leave the numbers to the military," he said. translation: the main task | is with our ministry of defence, and that is to force the enemy from our territory. 0ur adversary will, of course, receive a fitting response. and, without doubt, all our objectives will be met. as ukrainian troops have moved in, residents have moved out. officials say that more than 120,000 people have been evacuated in kursk region,

and thousands more in the neighbouring region of belgorod. there are fears of a ukrainian incursion there too. what is happening is huge. for the first time in more than 80 years, foreign troops are fighting on russian soil. and yet the country's leadership describes this as a provocation, a terrorist attack. the kremlin still avoids using the word war, as if to tell the people there's no need to panic. 0n the streets of moscow, no shock — just resignation about ukraine's offensive. "i'm not surprised," 0lga says. "it's a border area and this war has been going on for some time." what we all want is peace, and, like, the quickest resolution of this conflict. in the meantime, these volunteers are trying to do something. in moscow, they've organised

a collection of food and clothes for the evacuees. there are people who lost their homes. they need shelter, they need food, they need supplies. it was their country that invaded ukraine. russians are now having to deal with unforeseen consequences. steve rosenberg, bbc news, moscow. gordon corera, our security correspondent, is here. nothing like this has happened to russia since the second world war. one wonders, are the ukrainians really going to try to hold this territory? it really going to try to hold this territo ? , ., ,., really going to try to hold this territo ? , ., ., , territory? it is a bold and may be risky gamble _ territory? it is a bold and may be risky gamble by _ territory? it is a bold and may be risky gamble by ukraine. - territory? it is a bold and may be l risky gamble by ukraine. resident zelensky suggested this as a defensive move, going after the places where russia has been attacking ukraine. it is possible that ukraine could try to keep some of that territory as a bargaining chip for any future negotiations,

but it is very risky and a lot of military analysts think that might be dangerous, because russia will do everything it can to get that territory back. it will amass a huge amount of force. it might not be willing to do what it does in some other countries, lay waste to the territory, because after all it is a russian homeland. but still, ukraine would lose some of its best troops, which it has committed. but even if ukraine had to withdraw, they might see it as a real victory. why? it has forced russia to worry about its borders, it might make russia redeploy forces to protect those, taking some pressure off ukraine where it is fighting inside its own territory. not much sign of that yet, but that will be a help. and a psychological blow on russia by ukraine, for the ukrainian people, for their allies, suggesting that after a year when they have been on the back foot they can take the fight to russia. how it plays out, we will see in the next few days. gordon, thank you. thousands of people are being evacuated from their homes in greece, as wildfires spread

through forests and villages. and tonight the fires are reported to have reached the suburbs of athens. the emergency services say homes have been destroyed in varnavas, north—east of the greek capital. the nation is now on high alert, with soaring temperatures and strong winds expected to persist in the coming days. with the latest, jess parker is live in athens for us now. good evening. well, behind me is a timber yard that it seems has been caught up in the path of displays. you can see the huge amount of smoke, and we can really smell it here in the air. there are firefighters all around, some are working to try to contain the blaze, others are monitoring the situation, others are monitoring the situation, others are monitoring the situation, others are just lying on the ground, perhaps trying to recover after what has no doubt been an exhausting day. a picture of despair.

"0ur houses are burning," says this woman, a cry into one of the many smoke—filled streets to the north—east of athens. translation: complete destruction. the fire was coming from all sides for 48 hours. as soon as we called the fire department, the firemen came right away. i couldn't believe it. and as the blaze reached the outskirts of greece's capital, look at this. a thick cloud hung over the acropolis, the ancient citadel covered by a smoky mist. residents have been hauled from their homes. schools, hospitals and businesses abandoned, too. people who have had to flee tell of their terror. translation: the flames surrounded me. _ i couldn't see. i hit a pine tree and this happened. flare—ups and hotspots make these blazes hard to tackle. people use whatever they can. high winds and heat have allowed the flames to spread but this

is a longer term problem. greece and this region are no strangers to wildfires, and scientists warn things are getting worse because of climate change. the hottestjuly on record in greece came after a warm winter. we also have this very, - very dry fuels, which contribute to the rapid spread of the fire, and also they increase - the chance of having spot fires generating and very| quickly expanding wildfires. overall, i would say that it's another very difficult day, l and the situation right now in terms of the fire spread and the fire - behaviour is extremely difficult from the point of view - of controlling the fire. the searing heat is set to continue here over the coming days. help is being sent from other countries as greece defends its people and its capital.

now, there is anger and grief in greece tonight, including in this region, that this is happening yet again. now, the cause of these places isn't yet known, but we have had an update from the fire service tonight. they say the situation, overall, is improving a little bit. they are no longer tackling one major fire front, but rather lots of individual pockets of fire. but they do say that conditions remain dangerous or potentially new fires, notjust dangerous or potentially new fires, not just tomorrow, dangerous or potentially new fires, notjust tomorrow, but over the coming days as well. a doctor who treated valdo calocane, the man who fatally stabbed three people in nottingham last year, had warned that his mental illness was so severe, he could end up killing someone. calocane�*s mother and brother have told bbc�*s panorama programme that this was one of a series of missed opportunities over three years that could have prevented the killings. calocane was sentenced to an indefinite hospital order for the manslaughter of ian coates and the students barnaby webber

and grace o'malley kumar. here's navtej johal. for so long, we had thought that it would end in tragedy. but i thought the tragedy would be him taking his own life, and it was, like, infinitely worse than that. the family of valdo calocane are talking publicly for the first time. in 2023, he fatally stabbed students barnaby webber and grace o'malley—kumar, and school caretaker ian coates. he also seriously injured three others by driving into them. the outcome of the case caused deep anger and pain to the families. valdo calocane was convicted of manslaughter for the killings, and is detained in a secure hospital. the families of his victims believe that, although he was mentally ill, he knew what he was doing and should have been convicted of murder and sent to prison. calocane had been diagnosed with paranoid schizophrenia in 2020. we've got a bunch of the medical records from valdo's time in the care of nottinghamshire health trust. the family only received these

records after he was sentenced for the killings, and have shared them with bbc panorama. they reveal that three years before the nottingham attacks, a psychiatrist during a ward round had expressed serious concerns. my brother was so psychotic that the doctor notes, "there seems to be no insight of remorse, and the danger will be that next time, this will happen again, and perhaps valdo will end up killing someone." we know valdo's care wasn't up to standard, but reading this note isjust beyond anything. you think, this could have been avoided, you could have done something. richard taylor is a forensic psychiatrist. he didn't treat calocane, but has been an expert witness in more than 150 court cases. have you ever seen it written down in medical notes? that the patient could potentially go on to kill someone? um, i... i can't recall of a case where i've seen that written down in the medical records.

if it's that unusual and potentially that serious, what would you expect to happen? if a psychiatrist is committing themselves to a potential risk of homicide, then i think that's something that i would expect to be taken seriously. valdo calocane was detained under the mental health act four times in two years, each time following a violent incident — but neverfor longer than seven weeks. one of those violent incidents involved chris young. in 2021, valdo calocane moved into private student accommodation, sharing with him and three others. young had confronted his flatmate about leaving the bathroom in a mess. calocane tried to punch him, and then put him in a headlock. police didn't charge valdo calocane. how did you feel about valdo calocane? i thought he was someone with serious mental health issues. so i didn't think he was a bad person necessarily. i thought he was an ill person. but i definitely did not think he should have been walking around on the street.

i didn't think that was what was best for him. i don't think he was ever really treated. he was sort of managed, like, so he had interventions. but with regards to a proper, i guess, treatment plan, i'm not sure that we ever saw that. nottinghamshire healthcare nhs trust says it's committed to preventing such a tragedy reoccurring, that work continues to improve the safety and quality of services for patients, and to give its full support to learn from the events ofjune last year. the care quality commission is due to publish a report into valdo calocane�*s care tomorrow. calocane�*s family say the missed opportunities in his care are the product of a system which they say needs urgent reform. navteonhal, bbc news. alison holt is here, our social affairs editor. it does seem an extraordinary medical opinion that a man might be able to kill someone, could kill

someone, and yet nothing is done on that advice?— that advice? well, as you say, it is an extraordinary _ that advice? well, as you say, it is an extraordinary case. _ that advice? well, as you say, it is an extraordinary case. certainly i an extraordinary case. certainly here we seem to have detailed missed opportunities to intervene, and provide valdo calocane with the sort of treatment he clearly needed. sectioned four times in two years, relatively short hospital stays and a limited amount of work could be done with him in that time. missed appointments in the community. despite that, he was discharged to his gp. tomorrow we will hear from the care quality commission, the regulator, about its views. it has taken a deep debris detailed look at valdo calocane�*s medical records and what happened to him. but we already know that it believes that services in nottinghamshire have been struggling for the last five years. it points to variable care. and people having real difficulties accessing the support they need.

victims to get answers. and as the treasury warns departments about tough decisions ahead at the spending review, we have a top political panel with us. newsnight is on bbc two, bbc news and iplayer at 10:30pm. two 12—year—old boys have become the youngest to admit taking part in the recent disorder in the uk. they can't be named because of their ages, with one of them caught on cctv throwing an object at police during unrest in southport. he admitted violent disorder at liverpool youth court. the other threw a missile at a police van in manchester. he admitted two charges of violent disorder. they were among dozens of people convicted today, following widespread disorder in numerous towns and cities in the wake of the fatal stabbings of three young girls in southport. so far, 975 people have been arrested, with 546 charged. an 11—year—old girl has been seriously injured, and her mother was also wounded, in a knife attack in leicester square in central london, one of the busiest tourist areas

in the capital. a man has been arrested. members of the public helped hold the attacker down until the police arrived. here's frankie mccamley. just after 11.30 this morning, police were called here following reports that an 11—year—old girl and a woman had been stabbed. when officers arrived, a security worker and members of the public had detained a man. i heard a scream. and ijust went outside and saw one guy was having a knife. and the moment i saw it, ijumped on that guy and grabbed his hand in which he was having a knife. and then ijust put him down the floor and kicked the knife away from him. and in the meanwhile a couple of more guys came as well and they got on top of him and just held him forfour orfive minutes, and in the meanwhile the police arrived as well. hearing screams, many tourists fled the scene. they didn't know what was happening now. so i told them just calm down, i'm going to go to a safe place. but theyjust wanted

to go back to the hotel. leicester square is usually a fun and family—friendly area. today, part of it has been cordoned off. it is now a crime scene, with bloodstains on the pavement behind me. forensics have been carrying out a fingertip search, taking photographs inside, trying to figure out exactly what happened here, in an area packed full of tourists who have come to see the sights. but some today saw a horrific attack instead. a 32—year—old man was arrested. police don't think the suspect and victims were known to each other, but officers have praised those who bravely put themselves at risk and showed the best of london in doing so. frankie mccamley, bbc news, central london. sir keir starmer has been speaking with the new president of iran as part of international efforts to de—escalate tensions in the middle east. in a call lasting more than half an hour with masoud pezeshkian, the prime minister warned any action by tehran in response

to israel's assassination of a senior member of hamas, risked pushing the region closer to all out war. wyre davis is live injerusalem. it has been a frantic day of diplomacy. it has been a frantic day of diplomacy-— it has been a frantic day of diloma . , , diplomacy. yes, there has been increasingly _ diplomacy. yes, there has been increasingly credible _ diplomacy. yes, there has been| increasingly credible intelligence reports and perhaps an increasing expectation in the region that iran is about to follow through with its vow to retaliate against israel, either directly or through a proxy like hezbollah for what are perceived to be israeli attacks in iran and southern lebanon against senior hezbollah and hamas figures. how those iranian attacks will take place, we don't know, nor when. but there is increasing diplomatic and military pressure on iran not to follow through. the americans have stepped up their naval presence in the region. european governments have urged iran not to proceed with the attacks. keir starmer has spoken tonight for half an hour with a new

iranian president, emphasising the international pressure, and the fact an iranian attack mightjeopardise peace talks planned between hamas and israel later this week. but the talks themselves might not happen because we cannot the new leader of hamas or the israeli prime minister, will they make the necessary sacrifices to achieve a peace deal and release the hostages being held in gaza? . ~ and release the hostages being held in gaza? ., ~ i. ., ., , after a successful olympics for team gb, the athletes returned to london to be greeted by cheering crowds. they won 65 medals in all, 1a of which were gold. it comes as the diver tom daley, who won a silver medal in the pool in paris, announced his retirement. dan roan reports. it is hard to say goodbye to such a games, but after another major medal haul, team gb enjoyed an upbeat departure from paris earlier. for some, the celebrations continued on thejourney home,

before returning to st pancras and one last moment together. the homecoming especially emotional for one athlete — five—time olympic medallist tom daley announcing his retirement after his fifth and final games. it's really hard to talk about. but i have to hang it up at some time, so... but i'm really happy with how everything's gone. ijust think it is always hard when you say goodbye to your sport. so ijust, yeah, lots of things to process, but i think it's the right time. others, just delighted to be reunited with family. i'm so happy to be back, just to see this little guy, it's the best thing. to be back celebrating with the team gb fans as well,

the noise has been incredible. the fact everyone has turned to see us, it really is amazing. keely hodgkinson gets the gold! from defining victories... the olympic champions! ..and new stars in new sports... and it is gold for ellie aldridge! ..to emotional farewells. saying goodbye to this extraordinary player. this was another games to savour for team gb. an historic first. their 65 medals equalled their haul at london 2012, but the 1a golds and seventh—place finish were the lowest for 20 years. we are a bit further down the medal table than maybe we've been used to. it's a strategic ambition to be top five, but it's not a target in the same way. that's not what we aim for. last night's spectacular closing ceremony, featuring a dramatic appearance by tom cruise. the hollywood star beginning the olympic flag's journey to the next hosts, los angeles, brought the curtain down on a ground—breaking games. paris was a reminder of what makes this compelling sporting spectacle so special. leon marchand is going to win the gold! the face of the games and its most decorated athlete, french swimming sensation leon marchand, hailing its impact.

it's been amazing, beautiful. people are loving it, you know? at first, parisians were leaving the city. now they're coming back to see the games. there's something magic about it. after the covid—affected games at tokyo three years ago, organisers here will be delighted that for many, this is what paris 2024 will be remembered for — large, full crowds and stunning settings. this, a major boost to the olympic movement. but there was no shortage of controversy too. the opening ceremony on the seine required a vast security operation that brought major disruption to parisians. and the early bad weather also led to concerns over pollution in the river, with swimming events affected. what was the biggest challenge for you, and was there anything you would do differently now? i think it all was a challenge, because we need to be very organised.

it was wonderful for us to see that we did it, we did it. we worked together and people are very, very happy with that and very proud. above all, these games showcased a city and provided a true sporting spectacle. among the greatest ever? they mightjust be close. dan roan, bbc news, paris. it's been quite a discovery on mars, as scientists say they've identified liquid water on the planet, deep in its rocky outer crust. the findings come from a new analysis of data from a nasa probe, that touched down back in 2018. victoria gill has that story. the red planet. for years, scientists have searched for the secrets of its watery past. its surface is marked by channels from ancient rivers, but it's now a desert. this latest study has finally found the planet's missing liquid water, buried deep in the martian rock.

to locate it, nasa had to send a very sensitive piece of robotic equipment. lift—off of the united launch alliance atlas v rocket. and that's what they did back in 2018... touchdown confirmed. ..when i was at nasa'sjet propulsion laboratory as the team celebrated the successful landing of the mars insight probe. it will be sending its data back here, to mission control at nasa in california. it carried a seismometer, a device that picked up vibrations from inside the planet — marsquakes. during its four years of quietly listening, insight provided scientists with a record of seismic activity, and that has painted a picture of the internal structure of mars. the probe recorded more than 1,300 quakes, and the researchers have now studied that record in detail, analysing exactly how mars moves. the vibrations reveal what the planet is made of, and they showed that deep in the rocky martian crust,

there are reservoirs of water. we've identified places on mars where there are large amounts of liquid water. you know, water is the most important molecule in shaping the evolution of a planet and its climate. and we've identified how much of it is present and where it's sitting. this martian groundwater is between 10 and 20km beneath the surface. it'll be difficult to reach, but it could guide scientists to another promising target in the ongoing search for signs of life on mars. for now, though, this has uncovered a secret about the history of the red planet that has been buried for billions of years. victoria gill, bbc news. some of us were treated to a spectacular sight overnight, of shooting stars lighting up the sky. it's the result of the perseid meteor shower passing through the earth's atmosphere, and it'll be visible again tonight, beginningjust after midnight and ending about an hour before sunrise. it's officially been

the hottest day of the year, with many parts of the south and east of england feeling intense heat, as duncan kennedy reports. whilst paddling may have replaced punting for some on the cam, there was no escaping today's heat. cambridge recorded the uk's highest temperature this year, 34.8 celsius. that's more than 10 degrees above average. at lowestoft in neighbouring suffolk, sea breezes may have lowered the temperature to the high 20s, but that still brought out the sun—seekers. it also meant a day of vigilance for those on duty. we are already getting busy, with a constant stream of people coming down onto the beach. but so far, we haven't had any major problems, and the lifeguards have been on top of everyone, making sure we are giving out the safety advice needed to keep everybody safe and enjoy the day. it was the same on the south coast where water temperatures were just as inviting.

this was lee—on—the—solent, which saw families enjoying the school holidays and temperatures similar to southern spain. what do you make of the weather? lovely, very nice. hot and sunny, just how we like it. can it ever get too hot? they are talking about some places being in the 30s today. yes, it can be too hot. that is why we have come out early and then we go home in the heat. a heat that has brought messages of caution from a range of organisations. these high temperatures have seen the met office issue yellow heat warnings for a series of areas across the south and south—east. organisations like age concern have produced a range of advice measures for elderly people to make sure they take care whilst the hot weather continues. but the heat has broken down in places, causing storms. this fire at aviemore in scotland was caused by lightning. it is a reminder of the power of our weather to create delight

but also destruction. duncan kennedy, bbc news. this programme continues on bbc one. highest temperatures across to east anglia, the southeast and lincolnshire. temperatures have reached 32 degrees in bedford and bury st edmunds but it was cambridge that set the highest temperature of the year so far. that heat is ebbing away. through the rest of the week it is going to be somewhat cooler and whilst there will be some sunshine, there will be rain at times as well. these are the temperatures at the end of the night, still pretty warm across south—eastern areas but a more comfortable 10—11 elsewhere. more cloud and rain coming into the far west by the end of the night. this cloud and rain will move very slowly eastwards, further into scotland,

northern england, wales and the south—west. but three years after one warned he could end up killing someone, he went

on the rampage in nottingham. what went wrong?
