policing 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 in what's known as a ticket permitting them to carry weapons. one 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, i would. 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 h52 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 h52 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. staying with manchester — the first bus services to be brought back under public control in england in almost a0 years have started operating in the region. outside london, bus networks zre franchised to private companies to run, but the local authority sets the fares, timetables and routes.

the mayor of greater manchester, andy burnham, says the new buses may show the need for "more public control and ownership of critical services". live now tojessica lane in bolton. good afternoon, what does this mean for the people of greater manchester?— for the people of greater manchester? ., , manchester? good afternoon. many --eole manchester? good afternoon. many eo - le we manchester? good afternoon. many peeple we have _ manchester? good afternoon. many people we have spoken _ manchester? good afternoon. many people we have spoken to _ manchester? good afternoon. many people we have spoken to today - manchester? good afternoon. many people we have spoken to today say that what they really want from buses, from public transport is for it to be reliable, for it to be affordable and for it to take them where they need to go. and those are the things that have been promised here as the bus and the trams come back under local government control. as you said, it is the first time in 40 as you said, it is the first time in a0 years that deregulation has been reversed in england. there are promises that means the local council will be in charge of the fairs, the roots, the timetables and

they say it will make a big difference. you mentioned andy burnham, he is the regional mayor for greater manchester and this has been on his to—do list for quite some time. he says he thinks it will make a real difference. a year or so ago, they introduced a cap on a single bus ticket, so made the pricing more simple for people and they state that has meant lots more people using the buses. it is hoped the upward will continue, as they make notjust the ticket but the route simple and easy—to—use and also more reliable. elsewhere around england, it is thought they will be watching how it is working here, as other regions might be looking to introduce a similar system and may be bringing everything back under public control again as far as the public control again as far as the public transport goes. really, people in bolton saying if the buses and trams are running well and they are cheap and go where they need to

90, are cheap and go where they need to go, they are frankly, on—board with the new system. go, they are frankly, on-board with the new system.— the new system. jessica in bolton, thank ou the new system. jessica in bolton, thank you very _ the new system. jessica in bolton, thank you very much. _ next this hour, let's turn to one of the world's longest running conflicts which has been in the headlines this week. 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 their area. bbc russian service's olga 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. 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 a8—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. in the last few moments, arminian officials have said they are preparing to meet azerbaijan leaders on october the 5th, just over a week away. that is coming in from the afp news agency. meanwhile, the president of armenia has had his government is ready to welcome what he called their brothers and sisters from nagorno—karabakh. more on that story when we have it. now it's time for a look at today's sport with olly foster. there are five matches in the premier league today, four of them kicked off about 15 minutes ago. it's the first north london derby of the season at the emirates stadium. david raya keeping his place in the gunners goal and brennanjohnson given his

first start for spurs. no goals yet. pretty cagey opening stages. and there are no goals in any of those two o'clock kick—offs in the uk at brighton, chelsea and liverpool. sheffield united are looking for their first win. they have lots of areas where they can hurt us. we have to approach the match like we did in the brentford match, we were spot on with our mindset and spot on with the importance of the game and we responded really well. we are maybe not 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 formula one 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 an 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 have 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. for the players, probably not, after defeat you want to get back and play straightaway. for coaches? maybe, we have been able to train hard, we have been able to train hard, we have had social time with our families and we are further ahead to really attack these next three games. 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 oleksandr

usyk. ethiopia's tigist assefa has shattered the women's marathon world record by more than two minutes with a stunning victory in berlin. the 29—year—old clocked two hours 11 minutes 53 seconds in the german capital to eclipse the mark of 2 hours ia minutes s 0a secs set by kenya's brigid kosgei at the 2019 chicago marathon. the victory saw assefa defend her title from 2022. she also took $100,000 in race wins and bonuses for that record. 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. the usa is now 10—9 up. there is live commentary as well. but i will be back with another update in the

next hour. nasa's seven—year mission to collect a sample from an asteroid 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. with more here's our science editor, rebecca morelle. the sun is not up here at the military base in utah, but preparations are under way. the helicopters are getting wheeled out ready to take the recovery team out to the landing site once the capsule comes down to the ground. but the final descent for this mission, you have to remember it has been a seven—year mission, has travelled billions of miles through the solar system but the next 50 minutes will be perilous. the capital will be travelling at 27 miles an hour —— 20

7000 miles an hour. two parachutes will open which will hopefully take it down to the desert floor for a soft landing. the recovery team, in these helicopters you have just seen, they will be heading out to the site to bring it back to the base. it will be a nerve—racking last few moments of this mission, which has been going on for so long. there is a sense of nervous anticipation and excitement. there are some very good reasons to go to all of this effort. bennu is the most dangerous rock in our solar system. it tops nasa's list of hazardous asteroids. if you want to think about ways to stop it and one really good way to do this is to study what it is made up. the second reason is, bennu is a relic, left overfrom reason is, bennu is a relic, left over from the early formation of our solar system a.5 billion years ago and it has remained unchanged. it is and it has remained unchanged. it is a bit like a time capsule, which

gives scientists an insight into our own origins, how the planet formed and it could answer some questions like is the earth habitable, for example? scientists are eager to get their hands, carefully gloved hands, if to say because contamination is important with this sample. they are eager to get their hands on it, but first things first, it needs to make it safely down to the ground. let's now speak to dr natasha almeida, curator of meteorites, natural history museum here in london. very good to have you with us. what are you excited about when it comes to this asteroid? so are you excited about when it comes to this asteroid?— to this asteroid? so much. it is the laruest to this asteroid? so much. it is the largest sample _ to this asteroid? so much. it is the largest sample return. _

the conservatives. they are places that are quite leafy and not keen on huge numbers of new housing developments. has been controversy about targets within those areas before. the government has had to step back in the face of concerns from its own backbenchers from imposing specific of homes on particular local areas. what the liberal democrats are proposing, they want to drop this overall target of building 380,000 homes a year and replace it with one of building 150,000 social homes. the argument for that is having an overall target for all private developmentjust overall target for all private development just leads to overall target for all private developmentjust leads to develop a lead building that provides the wrong kind of homes in the wrong places, homes that are too big and not what the local area needs. so ed davey has said that a community led approach actually would deliver more homes in the long run.— homes in the long run. helen, what else has been _ homes in the long run. helen, what else has been on _ homes in the long run. helen, what else has been on the _ homes in the long run. helen, what else has been on the agenda - homes in the long run. helen, what else has been on the agenda at - homes in the long run. helen, what else has been on the agenda at the| else has been on the agenda at the lib dems conference? i am

introduce what they're calling a mental health mot which people would be entitled to a particular points in their life. there would be an increased focus on mental health. helen, the lib dems are keen to pick up helen, the lib dems are keen to pick up on some of the successes they have had in recent by—election, where they have stolen conservative voters. realistically, how optimistic are they that in an up—and—coming general election they can sweep in and still many more voters from the conservatives? the liberal voters from the conservatives? tue: liberal democrats voters from the conservatives? tta: liberal democrats are voters from the conservatives? tt2 liberal democrats are always optimistic, it is fair to say. there is a real sense in this conference that yes, they do think they can build on their position and they have had these spectacular by—election wins over the last four years. they have had four of them and they do think they can use some of the strategies they have employed to win those to win more seats, particularly from the conservatives. they say they are best placed in a number of areas to do that and they think they can really tap into the

concerns of voters have and the dissolution many voters have with some of the things the conservatives have been doing in recent years and they can really tap into that and become the choice of some voters to really up the number of seats they have at the next general election. there is a sense of optimism here and that is despite the fact they haven't really moved much in the opinion polls, not in the way that labour has in the next four years but they are confident they can make gains at the next election. tqm. gains at the next election. 0k, helen katz. — gains at the next election. 0k, helen katz, thank— gains at the next election. 0k, helen katz, thank you - gains at the next election. 0k, helen katz, thank you very much for now. 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. stay with us here on bbc news. hello. some wet and windy weather is developing at the moment and set to move into the north—west of the uk. western scotland will see the largest rainfall totals as we go to the rest of the day and overnight with 30 to 50 millimetres, double that over the high ground and that could cause some flooding issues. as this rapidly developing area of low pressure begins to form a move quickly to the north west of scotland, we could have some very strong gusts of wind developing as well. this afternoon we have rain around, some increasingly gusty winds for northern ireland. wet weather for northern england and scotland with another band of rain set to move into western england towards the end of the afternoon and early evening. but leave central and eastern areas with dry and bright conditions and it will be a mild

night for all. overnight tonight, could see strong winds for the hebrides, thus potentially reaching 60 to 70 miles an hour, maybe even stronger. as well as those potentially very strong gust of wind looking a heavy rain moving northwards and eastwards across scotland. band of rain moves across england and wales but by the time it reaches eastern areas, it won't be too heavy. but it will be quite gusty for a time. temperature those of a night, 12 to 15 degrees and i'll start a monday. monday is a day of sunshine and showers. frequent and heaviest will be across north and heaviest will be across north and western areas. dry weather for wales, east anglia and southern counties of england. temperature is above average, ranging from 17 to 22 degrees. into tuesday, a couple of weather systems kind of merging and ganging up on the uk. i think tuesday, unsettled day, rain at times probably best sums up the weather. the rain could be heavy with rumbles of thunder mixed in, may be turning brighter in the

afternoon in northern ireland but the risk of heavy showers. mild for the risk of heavy showers. mild for the time of year, 16 to 22 celsius. the middle part of the week, potentially disruptive weather on the way and the deep area of low pressure moves into the uk. this is bringing heavy rain and strong gusts of wind. in line, thus reaching 50 to 60 miles an hour, but around some of the irish sea coast, gusts could get up between 65 and 80 miles an hour to 60 miles an hour, but around some of the irish sea coast, gusts could get up between 65 and 80 miles an hour so potentially damaging, disruptive gusts of wind towards the middle part of the week.

this is bbc news, the headlines. questions surround the future of the uk's high—speed hs2 rail line. speaking to the bbc, senior cabinet minister grant shapps says it would be "crazy" not to review the project amid rising costs and inflation. the fate of ethnic armenians in disputed nagorno karabakh is hanging in the balance as their leaders say most will likely leave their historic homeland — now controlled by azerbaijan. thousands are without food or shelter — and only one aid delivery of 70 tonnes of food has been allowed through. nasa awaits the return of a space capsule carrying dust samples from what's described as the most dangerous rock in the solar system. scientists hope the osiris—rex samples from the osisemission could reveal new information about the formation of the planets. and in the uk — a review into police carrying weapons. the home secretary says armed police must not fear "ending up in the dock for carrying out their duties."

the report suggests more than a hundred met officers have
