general assembly haven taken place. we'll start with ukraine and a renewed appeal by president volodymyr zelensky hoping to convince world leaders to stick by his country's side as it continues to fend off russia's invasion. it's a rare visit across the atlantic for mr zelensky, and his first time appearing in person at the summit since the war broke out. he gave a stark warning that russian aggression could expand beyond ukraine, saying it was an unrelenting threat that would not stop at ukraine's borders. look, for the first time in modern history we have a real chance to end the aggression on the terms of the nation which was attacked. and this is a real chance for every nation to ensure that aggression against your state, if it happens, god forbid, will end, not because your land will be divided

and you will be forced to submit to military or political pressure, but because your territory and sovereignty will be fully restored. mr zelensky won't return home just yet. already he's had a full schedule in the us, as he presses for more international support. on monday, he visited ukrainian soldiers undergoing rehabilitation here, in new york. on the sidelines of the general assembly, he'll also meet with various heads of states and officials. then on thursday, zelensky is expected to travel to washington to meet us presidentjoe biden as well as leaders of congress. mr zelensky also dismissed efforts to broker a peace deal without ukraine's involvement, characterizing russia as an unreliable partner and saying, "evil cannot be trusted." in his address to the general assembly, mr biden also took aim at the kremlin. if we allow ukraine to be carved up is the independence of any nation secure? i would respectfully suggest the answer is no.

we have to stand up to this naked aggression today and deter other aggressors tomorrow. and deter other would—be aggressors tomorrow. earlier, my colleague caitriona perry spoke to jens stoltenberg, the secretary general of nato, on the likelihood of that and on president biden�*s message of unity. it was a very important message because it is about protecting the territory and sovereignty of your cane but this is not only about ukraine, it is about all nations and the united nations because if we do not stand up for ukraine then no nation in the world is safe and that was a main message from the president and i totally agree with him. he was very strong as well that this is the second year that the gathering is meeting under the shadow of war. yet, the international community has appeared relatively powerless to stop that. well, many, many countries, more than 50 countries, are part of the us—led

effort to provide unprecedented level of military support to ukraine, united kingdom, many other nato allies, and this strong support to ukraine has enabled them to push back the russian invaders, to liberate the territory and now also conducting an offensive which is gradually gaining ground. so, nobody knows how long this war will last but we have seen that ukrainians have been able to make progress, not least because of the support from the international community. they may have made progress, but russia pushes on. the international community has not been able to stop russia, even though it's a member of the security council here. why is that? what else needs to happen? because what we have seen is that russia as a permanent member of the un security council is violating the core and fundamental principles of this organisation that is to respect the sovereignty and the borders of all the members. and therefore, it is important

to that they are criticised open — they care at the un. but even more important is that we stand by ukraine that we continue to provide support to them. and the bravery and the courage of ukrainian people has impressed the whole world. but i also think that president putin totally underestimated the strength of nato allies and partners in our resolve to provide support to ukraine. the support ukraine also is looking for his nato membership. what fair is that at the moment? well, we have the summit the nato injuly, where all the heads of state and government participated, and there we made important decisions to move ukraine closer to nato. ukraine has never been closer to nato membership, partly by the fact that we agreed one step instead of a two—step process towards the membership for ukraine. but we also read a big programme to ensure that

ukrainian forces becomes fully interoperable with nato forces and established also new nato—ukraine council. so, we are moving towards nato membership for ukraine and allies to stated clearly that ukraine will become a member of the alliance. shortly after president biden�*s speech, my colleague caitriona perry also spoke to the us ambassador to the united nations, linda thomas—greenfield, outside of the general assembly. thank you forjoining us. if we can look back at what the us presidentjoe biden has said. he had very strong words to the international community, really, about russian aggression into ukraine, saying the fundamentals of this whole organisation, of the un charter, had been put under threat, put at risk. is there broad support for that message, do you think? i broad support for that message, do you think?— do you think? i think the president's _ do you think? i think the president's message - do you think? i think the | president's message was actually much broader than that. i think what the world

was waiting to hear from the president was what we thought of thes tg's. they also appreciated our views on ukraine but he really talked about our commitment to reaffirming the goals of the stgs and that message went over quite well. on ukraine, he was a strong and he was clear, that this is a brutal attack on a smaller nation, it is an attack on the very values of the un charter, it is an attack on the united nations system, and it is something that we have to stand together to fight. he said that president putin thought that we would lose our patients and move away and he was very strong in stating that we cannot do that, we have to remain strong, we have to

remain strong, we have to remain committed to fighting this brutal war.— remain committed to fighting this brutal war. when you talk about standing _ this brutal war. when you talk about standing together - this brutal war. when you talk i about standing together though, president biden is the only one of the five members to say so, what does that say? mil of the five members to say so, what does that say?— what does that say? all the countries — what does that say? all the countries here _ what does that say? all the countries here are - what does that say? all the . countries here are represented at senior levels. president biden participation and his presence is a reflection of our commitment but we are engaged with a number of countries. there are 140 litres, and i do not know the exact number who are all here, the other p5 members are represented at senior levels and we will engage them at the levels that they are here.— they are here. president zelensky _ they are here. president zelensky will _ they are here. president zelensky will address i they are here. president| zelensky will address the gathering in person today and joe biden said the price of peace as far as russia was concerned was ukraine territory, capitulation and children. what is the international community going to do? it is a year and a half

into this conflict already. we're going to stay strong, we're going to remain committed to supporting until this is over. and the president was clear in stating that there is no—one who wants a piece of more than ukraine. we want peace but please cannot be at the price of ukraine giving up its territory, giving up its independence and giving up its children. —— but peace. liis= children. -- but peace. us- china relations, _ children. -- but peace. us- china relations, the - children. —— but peace. us— china relations, the president addressing that and the need to manage the competition between the two nations. is that something the us is planning for, conflict with china? it was clear from the president's statement that we are not planning for conflict, we awaken to avoid conflict and we are working to manage this relationship, to ensure that conflict never happens. you mentioned _ conflict never happens. you mentioned earlier, - conflict never happens. you mentioned earlier, the - conflict never happens. you mentioned earlier, the stgs which the president addressed

at some length. trillions more dollars needed to make these targets, as we had from the un the target the way, way behind where they should be. what can they do? we where they should be. what can the do? ~ .., where they should be. what can the do? ~ ., ., where they should be. what can the do? ., ., �* they do? we can do what we're doinu they do? we can do what we're doing this _ they do? we can do what we're doing this week, _ they do? we can do what we're doing this week, reconnected l they do? we can do what we're | doing this week, reconnected to goals, make commitments to ourselves to achieve those goals and that is what the president did today and that is what a number of countries are doing, showing that they are committed to the stgs. we had a very strong declaration that was passed by consensus and i think that says everything about where everybody is on ensuring that we achieve the stgs goals because our about people, about dealing with poverty and dealing with education and supporting women and girls so they are goals that we all support and we are the governing our efforts to

make sure we get there and, in the end, deliver to the people of the world.— of the world. climate change are big part _ of the world. climate change are big part of— of the world. climate change are big part of delivering - of the world. climate change are big part of delivering onl are big part of delivering on the stgs. it feeds into almost everything and the targets that need to be mad. what more can the international community do? pledge of support is one thing but action is needed. you pledge of support is one thing but action is needed.- but action is needed. you are exactly right. _ but action is needed. you are exactly right, action - but action is needed. you are exactly right, action is - exactly right, action is needed. the united states is taking action, we are encouraging other countries to take more action and we commit to achieve the climate goals because we know, as the secretary general said, two years ago, this is an existential threat to the world and we have to find a path forward to deal with issues related to climate change and we need to do it today, not tomorrow. ads, we need to do it today, not tomorrow— we need to do it today, not tomorrow. �* , ~ ., , ., tomorrow. a better, i know you are under— tomorrow. a better, i know you are under time _ tomorrow. a better, i know you are under time pressure, - tomorrow. a better, i know you are under time pressure, thank| are under time pressure, thank you so much forjoining us. thank you. britain's prime minister is considering a major policy shift on the government's

environmental commitments. that's according to multiple sources who have been speaking to the bbc. it could include delaying a ban on the sales of new gas and diesel cars, and phasing out gas boilers. our political editor chris mason reports. within the conservative party in recent months, a fuming row, a cost of living squeeze but extra costs feared forfamilies to meet green targets. long—term promises, short—term political pressures. and then, this moment... 13,965. in the london suburbs, the tory by—election victory this summer when many expected defeat. and the key issue? a costly clampdown on dirty vehicles imposed by the capital's labour mayor, an idea the conservatives oppose. cutting carbon matters, the prime minister has long argued, but a balance

has got to be struck. i'm committed to net zero, of course i am, but we would do that in a pragmatic and proportionate way without unnecessarily adding costs and burdens to families, especially at a time like now when the cost of living is a challenge for people with inflation where it is. let me explain how and why we are reporting this now, what we know and what we don't know. what we do know is the prime minister wishes these had not leaked and he has lost control of the choreography of his announcement, and i can tell you that downing street have asked government departments to consider delaying, watering down or not committing to eight environmentally related themes and we have reported a few already, let me read a few more... no new taxes to discourage flying, no policies to change people's diet and no measures to encourage carpooling. what we don't know yet is having considered these ideas, is exactly which ones he actually commits to. in new york this week as world

leaders gather at the un, intense debate about climate change and what to do about it. amongst those there, this conservative mp, who led a review into the approach of the government to net zero. this is going to be an economic disaster, and we are missing out already, we see the us where i am here at un climate week, turbo—charging their efforts towards a green industrial revolution. why do we want to fall behind? did your heart sink when you heard about this? we still have days in which the prime minister might want to change his mind so hopefully if he listens to this programme, he will reconsider. but some conservatives and others have long campaigned forjust this kind of policy shift. here was the last prime minister just yesterday. .. we showed as many other western countries already doing, delay implementing net zero

commitments such as the ban on new petrol and diesel vehicles from 2030. other environmental regulations which are hiking the cost of living like enforcing the replacement of gas and oil boilers should also be abandoned. tonight, labour said... this is an absolute farce, this is absolutely no way to run a country, late—night policy statements from the downing street bunker as ever driven by the absolute chaos within the conservative party with a weak prime minister. but there was no commitment from labour to restore any targets that are dropped. a leak within government and a huge row boiling over more than ever. around the world and across the uk, this is bbc news. let's look at some other stories making news. a russian court declined to hear an appeal from wall streetjournal reporter evan gershkovich, returning the motion to a lower court. gershkovich has been detained

in a moscowjail on espionage charges for nearly six months. he will remain behind bars until at least november 30th. if convicted, gershkovich faces up to 20 years in prison. according to a new court filing, president biden's son, hunter, will plead not guilty to federal gun charges. his attorneys are also asking for his initial court appearance to be held remotely by video conference. hunter biden was indicted last week on three charges connecting to a 2018 gun purchase. germany's interior minister is planning to force telecoms operators to curb the use of 5g equipment from huawei and zte after a review highlighted an over—reliance on chinese suppliers. the ministry will use a staggered approach to remove all critical components from the companies in germany's 5g core networks by 2026. you're live with bbc news. the united nations estimates

the war in ukraine has driven more than five million people from their homes there, and forced more than six million more people to cross into neighbouring countries including poland, hungary, and moldova. it comes amid lingering and escalating conflicts and natural disasters around the world. earlier, caitriona perry talked about that with high commissioner at the un's refugees agency filippo grandi. this is the year in which we have the highest displacement. it is notjust displacement. it is food security, it is health challenges we have everywhere. this is the most difficult year in years to mobilise money. the united nations has revised down its estimate of the number of deaths caused by devastating flooding in libya, to 4,000, with at least 5,000 missing. the extensive recovery process continues in the region. journalists were ordered out of derna — that's the libyan city devastated when two dams collapsed following flooding in the country's east. it follows protests from demonstrators furious over

the failure of authorities to protect the city from floods. irate residents of derna say the devastation could've been prevented, with officials blaming insecurity in the area for incomplete repairs to the dams after 2007. there are also reports that the mayor's house was burned down. our correspondent anna foster is in eastern libya with more on the protests. well, things changed to derna less than 24 hours after protest outside the main mosque in the city. many people gathered to express their anger against the authorities who they said had not maintained the dams properly, who had not protected to the people the way they should have done. there was anger towards the mayor of derna, there was anger was eastern—based authorities. and then just a few hours after that the suggestion that journalists would no longer be able to work in derna. so teams, including ours, were told that even though we have been working in the city, covering this over several days now, permission to be inside would no longer be granted.

the authorities say that that is because there were too many people, they say, hampering the recovery effort, getting any way of teams, they said, doing their work. but the timing of this is particularly interesting given that that dissent and that tension which was really starting to grow. and of course it's a tension that has known for a long time now, that push and pull between east and west, the two opposing governments, the two opposing authorities who both fight and vie for control of this country. and putting all of that to one side you still have survivors in derna, people who are living in schools, in some places, as we saw, in temporary buildings, doing what they can while this recovery operation continues around them. the numbers are still being disputed by various agencies in terms of how many people have lost their lives and how many people are still officially missing, but we know it is many thousands.

and day after day, as agencies say, the risk of disease, sanitation issues are only growing for people living in derna, as the operation to continue to recover the bodies of those victims from land and from sea goes on. an international research group says climate change made the heavy rainfall that prompted the deadly and destructive floods in libya up to 50 times more likely. earlier, at the united nations, i also spoke to the president of the international federation of the red cross francesco rocco about the humanitarian response in libya and to more disasters caused by climate change. mr rocco, thank you very much forjoining us on bbc news. i want to start with the catastrophic situation in libya right now. your organisation has said that what has happened in derna is a wake—up call to the world, because climate change made this catastrophe more likely. what you mean by that? i mean that we are supporting a group of scientists,

the world attribution group, the group that is working with our climate centre — weather attrition, sorry — and this is more again 50% likely to happen. this is the big news that is coming from this research. and we are talking about only 1.2 degrees. this is the reason why we are calling for this wake—up call to the international community. we have to act now. this is important to realise how the climate change is affecting the most vulnerable and, of course, this is not enough. we have to pay attention to preparedness, but infrastructure, which in derna we will understand better what has happened, but climate change is the most important thing to be focused on. does that mean what happened in derna could have been prevented ? maybe not. but could have been mitigated, yes. this is for sure.

so we are hearing that a united nations team that was supposed to travel to derna to help with the floods, that they were denied access, communications were shut down, some journals have reported that they were asked to leave. first of all, have your teams been able to access derna and the people who most need assistance? when it comes about this country, you know how difficult it is to access. this is not the first time, of course. now we're talking about this disaster but even in the past it has very difficult. but fortunately we have our libyan teams since the beginning and we have been providing support to our men and women that are working on the ground. unfortunately, since the beginning we have lost three volunteers. many international societies, italian red cross, qatar red crescent, saudi, turkish red crescent, so we are channelling to our organisation an important support on the ground because the needs are immense. we are talking about shelter, we're talking about water sanitation, we're talking about health. only one hospital in this

moment is working there now. given those conditions are you concerned about these reports that the libyan authorities may be restricting access ? we always not happy when you have restriction to the access. but so far we are able to have the access to our organisation and we are grateful to the libyan authorities for this. we hope they can have a dialogue with other organisations because we do need as much support as possible. i also want to ask about recovery in morocco. we know your organisation is in intensifying relief operations there after last week. that is especially because there is rain on the horizon and it is expected that possibly trigger landslides. are we expecting there could be more loss of life in morocco? of course. this is not a joke. when we make a call it's because there is a serious

threat. we know the weather conditions now with the autumn coming, especially in the mountains, there is a high risk for the people that are now in need of shelter so we are increasing now. it's not about food, it's not about water, fortunately the community in this moment is providing, a lot at country level, but we need, for example, blankets, mattresses, we are working a lot on shelter. this is the most important thing to prevent loss of life in the next days. given these dual tragedies we have been discussing, libya and morocco, what is your message to world leaders who have been gathered here at the united nations general assembly? that climate is one of the most important threats and then they have to work at community level for preparedness. preparedness is the key, so that community are really able to create resilience. this is not only a simple word, a word of the new centre, resilience is important at community level — just to mitigate, for example, we cannot prevent earthquakes. we can mitigate the damages.

thank you so much forjoining us. thank you. relations between canada and india have worsened after each country expelled diplomats in tit—for—tat moves on tuesday. it comes after canada alleged india's involvement in the murder of a canadian sikh activist. hardeep singh nijjar was shot dead outside a sikh temple in british columbia back injune, less than three years after india designated him as a terrorist. canadian prime ministerjustin trudeau said authorities are actively pursuing links between new delhi agents and the mr nijjar. india has dismissed the allegations as absurd. and before we wrap up this half—hour from here at the un, let's look ahead to wednesday's main events. ukrainian president zelensky is set to present the details of his ukrainian peace formula at a special meeting of the un security council wednesday. he describes these as "solutions and steps" that

will counter russia's military aggression. and, of course, there's lots of diplomacy on the sidelines of the main event. president biden will meet with israel's prime minister benjamin netanyahu. it'll be their first face—to—face meeting since the israeli leader returned to power last december. that wraps up our show for the cell. stay with us on bbc news. hello. we've got some fairly stormy, autumnal weather on the cards over the next few days. the remnants of ex—hurricane lee are moving in from the atlantic, bringing reasonably mild conditions, but also some strong winds and, for some of us, some heavy downpours, as well. we could see some localised flooding with some of this heavy rain that's on the way. so low pressure moving into the northwest — this frontal system here moves slowly from west to east over the next 24 hours or so, bringing those squally, strong winds and heavy rain. so, over the next few hours, we've got some rain across parts of scotland. it's becoming more persistent

for northern england, wales, and down towards the southwest of england, too. wherever you are, it's not a cold night — temperatures staying up in the mid—teens for many of us, just single figures across the far north of scotland. but through the day on wednesday, this band of rain pushes slowly southwards and eastwards. the strongest winds in and around that front could gust to more than 60mph around exposed coasts of wales, for instance. really breezy conditions, too, for central and eastern parts of england, although the morning will be dry and reasonably bright here. further north, then, during the morning, 40—50mph gusts — enough to cause some disruption across parts of scotland and northern ireland. a mix of sunshine and showers, but the gusts will strengthen to more than 60mph during the afternoon, and those gusty winds will reach the southeast of england, as well, with this rain becoming really quite heavy and persistent. you might hear the odd rumble of thunder around, as well. temperatures in the high teens, possibly 21 celsius towards the far southeast. reasonably mild, but that mild air, with its heavy rain and strong winds gets cleared away as we head through into the early hours of thursday morning. so, a colder night then wednesday night, thursday morning, many of us down into mid—single figures, i think.

but we'll start the day with some heavy showers already in the northwest, and they'll push their way slowly southwards and eastwards, across northern ireland and scotland. again, gales possible across the northwest. less windy by this stage, thursday, across much of england and wales — though sunny spells, scattered showers, but it will feel colder than it has done of late. into friday, another day of sunshine and showers. the winds rotating around that low pressure to the north, so gales again possible in the far northwest of the uk. less windy, i think, further south, but a cool, blustery, breezy sort of day — 14—18 celsius or so. looks like many of us should see a bit of a quieter day, less windy with some sunshine on saturday, particularly in the south. and then, we'll return to some blustery and showery conditions from sunday onwards. bye— bye.

voice—over: this is bbc news. we'll have the headlines and all the main news stories for you at the top of the hour, straight after this programme.

when the storm came, fractured libya was ill—prepared. half a year's rainfall fell in 24 hours. in daylight, as much as a quarter of the port city of derna was revealed to be gone. engulfed by flood water after two mountain dams failed. families were washed out to sea as they slept. the grim work to retrieve the lost is underway. with terrible force, the floods swept through this city. destroying homes, cars, bridges. there was no warning, no evacuation order. gently, the body of a child is recovered from the rubble. few here are being found alive. derna and libya are overwhelmed.

it's too much for those left grieving.
