live from london. this is bbc news injust under an hour, a nasa probe carrying asteroid dust that could reveal new details about how the planets were formed will return to earth. lam i am live here in utah where, less than an hour, we will see a capsule carrying these precious samples from asteroid bennu landing in the desert. the uk home secretary orders a review of armed policing — after dozens of officers withdraw from firearms duties after an officer is charged with murder. uncertainty surrounds the future of the uk's high speed hs2 rail line — the defence secretary says it would be "crazy" not to review

the project amid rising costs. ethnic armenian refugees from the nagorno karabakh enclave in azerbaijan start arriving in armenia — the first to arrive since azeri forces retook the disputed territory last week. hello, i'm rich preston. today is a big day for anyone wondering how life came to be on earth. nasa's seven—year mission to collect a sample from one of the largest asteroids in the solar system will reach its dramatic conclusion in just a few hours from now. the osiris—rex capsule contains rocks and dust from the surface of an asteroid called bennu, which scientists say could give important clues about how the earth was formed. and our science editor, rebecca morelle is actually in utah for us, waiting for the landing.

atmosphere away from it. the scientist will be handling it through these glove boxes, big boxes with a pair of gloves that you stick your hands in to handle the sample. so all of that will take some time and then you have to start doing the science, running the experiment is to figure out what the asteroid is actually made of. what chemicals are in there. you are looking for water, you are looking for carbon —based molecules, the organic building blocks of life, amino acids. are they similar to the ones we have here now, are they different? this asteroid dates back to four point billion years ago when the solar system was warming. so comparing what is on bennu with what we have here will be an interesting process. rebecca, thank you for walking us through that. we will leave it there with you now but hopefully we can check back in with you later. let's take a closer look at the scale of the asteroid. it measures 510 metres in diameter, which is slightly larger than five football pitches and much larger

than landmarks such as the eiffel tower and the empire state building. when the capsule containing the samples enters the earth's atmosphere, it will be travelling at a staggering 27,000 miles per hour — that's 7.5 miles per second. it will take about 13 minutes to touch down, during which time the earth's atmoshphere and a parachute system will slow it right down to ten miles per hour. the landing site is a remote military testing range deep in the utah desert. once the capsule has landed, it will quickly be retrieved via helicopter and taken to a specially built facility at nasa'a joson space centre in texas. now, live to lockheed martin space in littleton, colorado to speak to mark fisher, who's lockheed martin 0siris—rex spacecraft operations engineer. good to talk to you, this must be an exciting day so tell us about your

decided he could fill up the cup. we took that design to see if we could come up with something to pick up the sample. the second piece of technology that was important was artificial intelligence that could look at the surface. 0nce artificial intelligence that could look at the surface. once we found our location we were able to use this ai two directors right to that location, with all kinds of obstacles, the big boulders that we found that was surprising to us. these are highly complex missions, recently we have seen problems just getting to the dark side of the moon, for example. did you have any near misses, any moment when you thought, we cannot do this? i can wake u- thought, we cannot do this? i can wake up in _ thought, we cannot do this? i can wake up in the — thought, we cannot do this? i can wake up in the middle _ thought, we cannot do this? i can wake up in the middle of - thought, we cannot do this? i can wake up in the middle of the night and be worried about it but we have spent so much time with so many smart people over a long period of time, our processes from history and space, the design of the spacecraft

after a large number of metropolitan police officers stepped back from firearms duties. their decision is linked to the case of an armed officer, who was charged with the murder of a man. 24—year—old chris kaba was unarmed when he was shot and killed in south london last year. a met police officer appeared in court on thursday. joe inwood has this report. chris kaba was unarmed when he was shot and killed in streatham. he was driving a borrowed car. according to police, the vehicle had previously been linked to an incident involving a gun. chris kaba was hit by a single bullet, fired by a police officer. there was widespread outrage at his death, especially amongst london's black community. last week, his family were in court to see a police officer, who is only being referred to as nx121, charged with murder. they welcomed the prosecution but it's been met with concern by many of the officer's colleagues. in total, it's thought more than 100 firearms officers have handed

if in what's known as a ticket permitting them to carry weapons. 0ne former officer says he's not surprised. i was on armed response for 23 years. i was on vip protection and i hugely enjoyed the professionalism — the teamwork of it, and i would miss that. would i put my weapon down today? yes, iwould hand it in. it's not worth it. announcing a review, the home secretary said police officers have to make split—second decisions under extraordinary pressures. they mustn't fear ending up in the dock for carrying out their duties. officers risking their lives to keep us safe have my full backing. officers from other forces have now been drafted in to help patrol london — a job the police federation admits comes with responsibility but also accountability. joe inwood, bbc news. staying in the uk, defence secretary grant shapps

says it would be "crazy" not to look again at the rising cost of the hs2 rail project. a decision on the future of the birmingham to manchester part of the line is expected to be made by the government this week, following reports it will be scrapped. noor nanji reports. it's a grand project, first dreamt up in 2009. the aim — to speed up journey times and create more capacity. but hs2 has faced delays, cuts and spiralling costs. the original plan would have connected london to birmingham, and then leeds and manchester. in 2021, the section from birmingham to leeds was cancelled. then we heard the line might end in west london, rather than going all the way to euston. and now, the birmingham to manchester bit is in doubt as well. the last official estimate on hs2 costs — excluding the cancelled eastern section — added up to about £71 billion, although this was in 2019 prices. this morning, the defence secretary and former transport secretary

said no decision has been taken yet but that it's important to respond to the budget. every government has to look at the overall budgets and then make serious decisions, which go beyond the sort of back—and—forth in a studio like this... 0k. ..to say, is this affordable, under current circumstances? i'm absolutely confident, for example, that when those statements were made, no—one knew we'd be in a war in europe right now. 0k. all of the consequences, all of the costs and all of the inflation. and any government that doesn't go back and then look at it is crazy. mr shapps would not comment on whether or not separate plans for the northern powerhouse rail scheme between leeds, manchester and liverpool would still go ahead, even if the northern section of hs2 is scrapped. labour's been accused of sending mixed messages on hs2. we are supportive of h52 being built, but we're responding to rumour and leak. and, look, victoria, this is a really important

infrastructure project. what i say on your show matters because we, the labour party, hope to be in government next year. we're not going to make decisions about national infrastructure projects that involve tens of billions of pounds without all of the information being available. this weekend, business groups and political voices have been lobbying the government not to truncate hs2 further. in a letter organised by the rail industry, the leaders of 21 firms warn that discarding the leg to manchester will have serious implications for the uk economy. with pressure mounting, it's thought a decision could come as soon as the coming week. noor nanji, bbc news. now it's time for a look at today's sport with 0lly foster. hello from the bbc sport centre. it is all going on in the football, gold flying everywhere. five matches in the premier league, four of them into the second half. first north london derby at the emirates. it was

1-1 at london derby at the emirates. it was 1—1 at half—time, it is now to all, —— two all. you can see brighton, they have the lead over bournemouth. no goals at stamford bridge between chelsea and aston villa. and it is 1-1 chelsea and aston villa. and it is 1—1 between liverpool and west ham. the kick of coming up in the next couple of hours, sheffield united, still looking for their first win and they face newcastle united, who have won two and lost three of their five in the league so far. thea;r have won two and lost three of their five in the league so far.— five in the league so far. they have not lots five in the league so far. they have got lots of — five in the league so far. they have got lots of areas _ five in the league so far. they have got lots of areas in _ five in the league so far. they have got lots of areas in their _ five in the league so far. they have got lots of areas in their team - five in the league so far. they have got lots of areas in their team that| got lots of areas in their team that can hurt as if we are not right. we have to mentally approach the game against brentford where we were spot on in our mindset, we were spot on with the importance of the game. we responded really well, with maybe

not, you know, a magnificent display but we did enough to get the job done and we are going to have to get all the basics right if we are going to compete in this game. max verstappen is on the verge of a third world title, as he cruised to his 13th victory of the year at the japanese grand prix. verstappen's victory helped red bull secure the constructor�*s title with six races to spare, which is a f1 record. and the dutchman will be world champion for the third straight year if he wins in qatar in a fortnight. joining verstappen on the podium were the mclarens of lando norris and oscar piastri. two games in the rugby world cup on sunday. wales can qualify for the quarter finals with victory over an australia side that stands on the brink of elimination from pool c. what i'm happy at the moment, put some pride back in the welsh jersey. it doesn't take long to lose it. i don't think we had the respect

of the rugby world in terms of performance and results. that has been a big objective of ours over the last few months. scotland haven't played since the opening round of fixtures and have two weeks off. they have to beat tonga with a bonus point to have any realistic chance of getting out their pool that also incudes ireland and south africa, who they lost to in their first match. for the players, probably not, after defeat you want to get back and play straightaway. for us as coaches? maybe, we have been able to train hard, we have had social time with our families and we feel we are further ahead to really attack these next three games in our pool. and it was meant to be the night that britain's joe joyce got his career back on track. but instead, his hopes of challenging to become the world

heavyweight champion are all but over. joyce was stopped by china's zhilei zhang in their rematch in london on saturday night. zhang knocking joyce out in the third round, meaning he retains the wbo interim title and stays as the mandatory challenger to champion 0leksandr usyk. it's the final day at the solheim cup in southern spain, europe and usa were all square going into the singles. head to the bbc sport website for live text and commentary from the course. the latest, it is ten all. it could be a nailbiter in southern spain. i will have an update in the next hour. now to the world's longest running conflicts

in nagorno—karabakh. ethnic armenian refugees from the break away territory have started arriving in armenia. they're the first batch to arrive since azeri forces retook the disputed territory last week in a military operation. this comes as azerbaijan said it would reintegrate karabakh armenians. but local media in the enclave predict a mass exodus of them. nagorno—karabakh is a territory in the mountainous south caucasus of eastern europe and asia, between the black sea and the caspian sea. it's recognised internationally as part of azerbaijan, but large areas of it have been controlled by ethnic armenians for decades. this week, after azerbaijan launched a military offensive in nagorno karabakh, a ceasefire was declared. the agreement was that karabakh's military forces would be completely disarmed and disbanded, but now there are concerns over the fate of ethnic armenians living in the area who say that aid has not been getting through to them. bbc russian service's 0lga ivshina is one of fewjournalists who managed to reach nagorno—karabakh this week. she has just returned to azerbaijan's baku and has

sent us this update. i don't think we have that at the moment but we can bring you some live pictures from the border between armenia and azerbaijan. these are people arriving in armenia who have left the territory. early on, armenia's president said that these people would be treated as brothers and sisters. as i mentioned, one of a journalist from the bbc russian service has recently been to the territory. she is now backin been to the territory. she is now back in azerbaijan's capital baku and sent this update. this morning we got back from susa, which azeri authorities consider the capital of karabakh. we were among the very first journalists which were allowed in since the start of september hostilities. however, this was a tightly—controlled trip. so we were escorted into susa and shown a large display of weapons, including tanks, atcs,

automatic guns, rpgs and a huge amount of weapons all laid down by karabakh armenians in the recent 48 hours. this was one of the prerequisites of the ceasefire. the situation in karabakh however remains tense. azeri authorities say they are ready to provide security guarantees for all civilians in the region and they will only target armed rebels. however, karabakh armenians who are trapped currently in stepanakert are very worried about their security. first of all, it's a humanitarian crisis on the ground. people say food, water and medical supplies are lacking. there is no electricity and we were able to see with our own eyes, because susa is overlooking stepanakert, as soon as it became dark the city was pitch black, which was a stark contrast with a the brightly—lit streets of susa. azerbaijan says it has established

a few refugee camps and is ready to allocate refugees. however, karabakh armenians are highly suspicious. this decade—long conflict has seen a lot of bloodshed. both sides are accusing each other of war crimes. and there is a lot of mistrust on both sides, which doesn't help the process. however, despite all the statements, all the diplomatic agreements and calls to action, it's clear that the destiny of karabakh armenians is currently in azeri hands. within the last hour we have had a comment from the capital of armenia saying its leaders, along with azerbaijan's leaders are preparing to meet on october the 5th. that is coming in from the afp news agency and we will bring you more when we

have it. kosovo security forces have surrounded at least 30 gunmen in the majority serb north. it follows an ambush against police that killed one and injured at least one other. the eu's foreign policy chief, josep borrell, has described that attack as "hideous" and called for the culprits to be brought tojustice. serbia is yet to comment on the incident. reporter yasmin khatun dewan has more from the newsroom. the attack took place in the northern village of banjska. you can see it here, it's to the north of kosovo by the serbian border. according to official reports, it involves professionals using heavy weapons and two large unidentified vehicles. you can see this image from the scene of the attack, where nato troops were part of a long—standing kosovo force standing by the scene of the incident with local police officers. tensions have run high in kosovo following recent elections and the clashes that followed. relations between the albanian—dominated government and the serb minority community have been strained for years.

you can see images from those clashes there. nato, following those clashes, deployed an additional 700 troops to its almost 4,000 already based in the country to deal with the unrest in northern town of where those clashes took place, with some of its peace keepers injured in those clashes. the land locked country in the balkans borders albania and serbia. and it was a former province of the the former yugoslavia. serbian forces waged a brutal attack on the mainly ethnic albanian—populated territory before it saw independence in 2008. kosovo is recognised as a state by 99 united nations countries, including the us and the uk, but serbia, along with its key allies, chinese and russia, do not recognise its status, instead considering kosovo a part of its nation. of the 1.8 million people living in kosovo, 92 are muslim albanian, with around 6% serbian. you can see the majority serb areas in purple here. ethnic tensions have

been constant in kosovo, with eu—mediated talks to stabilise the situation currently stalled. also at the un general assembly, haiti's prime minister, ariel henry has called for urgent un action to bring stability to his country. he says the security situation has led to a new humanitarian crisis — displacing thousands of people. mr henry said kidnappings for ransom, arson, massacres, sexual violence, and people trafficking are all on the rise — since violent gangs took control. he told the general assembly the security council must act to authorise an international force, to help haiti's overstretched police and military subdue rampant armed gangs. the country's stability has deteriorated, as its largest economic driver — agriculture production — has slowed due to natural disasters like the devastating earthquake in 2010. this has led to illnesses, such as

cholera, spreading on a mass scale. meanwhile, political corruption has made it nearly impossible for the prime minister to manage the chaos. the un says more than 2,000 people have been killed in haiti since the start of this year. while the biden administration said they will not be sending troops to haiti, they will continue to offer financial and humanitarian support. us secretary of state, antony blinken, promised a further $65 million to help haiti's police, here is speaking about the the us is taking to support haiti. today, we are taking steps to impose additional visa restrictions on current and former haitian officials who are enabling the violence. with that step, we have designated more than 50 individuals. a second ship with ukrainian wheat reached turkey, despite russia's withdrawal from the un—backed grain deal. the bulk carrier — laden with more than 17,000 tonnes of wheat —

left the port city of chornomorsk in ukraine on friday, bound for egypt. it comes as ukraine is testing a new sea route avoiding international waters and using those controlled by nato members bulgaria and romania. a first ship — with 3,000 tonnes of wheat — has safely arrived to istanbul last week. in ghana, hundreds of demonstrators gathered in the capital accra on saturday for a third day of anti—government protests linked to economic hardship. dozens have been arrested for defying a police order not to assemble. 0ur newsroom reporter daniel dadzie has more. so, these are the scenes on the street leading up to the government in the capital for three days, the protests have defied the reigns, waving placards and nationalflags among others. they decry the high cost of living and lack ofjobs as they march under the watchful eye of riot police. the occupyjulorbi demonstration

began as a hashtag on x, formerly known as twitter. on thursday, the police picked up 49 of these protesters for violating the public order act and the gathering unlawfully. since then, these policemen have barricaded the street leading up to that very presidential residency but democracy hub gh which organises demonstration has vowed to occupy that very premises. don't we have the right to demonstrate? this is for the whole country, we have kids who have to do so much just to simply survive in the government does not care. the economy is facing its worst crisis with spiralling public debt.

it's going to grow from 3.1% in 2022.
