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 londons 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 its been met with concern by many of the officers colleagues. In total, its thought more than 100 Firearms Officers have handed in whats known as a ticket permitting them to carry weapons. One former officer says hes 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. Its not worth it. Announcing a review, the Home Secretary said Police Officers have to make split second decisions under extraordinary pressures. They mustnt 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. Its 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 its 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 . Im absolutely confident, for example, that when those statements were made, no one knew wed 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 doesnt 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. Labours been accused of sending mixed messages on hs2. We are supportive of h52 being built, but were 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. Were 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, its 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, onboard 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, lets turn to one of the worlds 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. Its 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 Services olga ivshina is one of fewjournalists who managed to reach Nagorno Karabakh this week. She has just returned to azerbaijans 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 its 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 doesnt help the process. However, despite all the statements, all the diplomatic agreements and calls to action, its 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 its time for a look at todays sport with olly foster. There are five matches in the Premier League today, four of them kicked off about 15 minutes ago. Its 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 oclock 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.

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 im happy at the moment, put some pride back in the welsh jersey. It doesnt take long to lose it. I dont 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 havent 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 britains joe joyce got his career back on track but instead, his hopes of challenging to become the world heavyweight champion are all but over.

Its 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. Nasas 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 heres 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 nasas 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. Lets 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 .
