hello. a very warm welcome to the a very warm welcome to the programme. programme. i'm sally bundock. i'm sally bundock. joe biden has lifted a ban joe biden has lifted a ban on ukraine using long—range on ukraine using long—range missiles supplied by washington missiles supplied by washington to strike inside russia. to strike inside russia. the decision, a major the decision, a major policy shift by the us, policy shift by the us, means ukraine can now use means ukraine can now use army tactical missile systems, army tactical missile systems, known as atacms, known as atacms, to defend its forces, to defend its forces, in russia's kursk region, in russia's kursk region, on ukraine's northeast border. on ukraine's northeast border. russian president vladimir russian president vladimir putin has yet to comment putin has yet to comment on the reports. on the reports. he previously warned the west he previously warned the west that he would consider that he would consider such a move to be a major such a move to be a major escalation in the conflict. escalation in the conflict. our diplomatic our diplomatic correspondent, paul adams, correspondent, paul adams, is in eastern ukraine, is in eastern ukraine, and has the latest. and has the latest. it's a powerful weapon it's a powerful weapon with a range of almost 200 with a range of almost 200 miles, capable of hitting

targets deep inside russia.

have in store. ukraine's electricity grid was the main target, triggering power cuts in several cities. and when the power goes, so, too, does the water. for the people of odesa, a long trudge to the nearest emergency supply. "i don't think we'll get water today," says yulia. "maybe tomorrow, in the evening." president zelensky congratulated the men and women of ukraine's air defences, including natalia grabarchuk, shooting down her very first cruise missile. "did it hit?" someone asks. "yes," comes the answer. in kyiv, parts of a missile shot down by ukraine's air defences, leaving a trail of destruction in its wake. when the sirens sounded, some headed for the capital's famously deep underground.

after almost three years, most now stay at home. but winter is approaching, and russian forces are advancing in the east. there's a renewed sense of pessimism and danger. a reminder of that tonight in sumy, close to the russian border — a missile landing in a residential area, killing ten and injuring dozens. paul adams, ten and injuring dozens. pauladams, bbc ten and injuring dozens. paul adams, bbc news, eastern ukraine. let's get reaction. let's speak to harrison mann, a former major at the defense intelligence agency at the us department of defense and senior fellow at win without war, a progressive foreign policy advocacy organisation based in the us. welcome to bbc news. what are your thoughts about this move?

the operationaljustification is to support ukraine trying to repel a russian counter offensive in kursk right now. the russian territory that ukraine ceased. but i think the timing and this decision in and of itself is inseparable from the results of the election two weeks ago. i think all parties including the biden administration understand this conflict is a bit of a race against time until donald trump takes over and president—elect donald trump has promised to end the war on day one and i think both russia, ukraine and the current administration expect that on terms favourable to russia or less sympathetic ukraine. president biden, who i think is already anxious about the legacy he will leave, tarnished both by gaza and his role in kamala harris�*s defeat, has always seen support for

nato and defence of europe as an achievement he is extremely proud of, so i think we can see this as a last ditch effort to try and do something to strengthen ukraine's hand before negotiations begin under donald trump and also we might see this as a change in the administration's assessment of the risk calculus of enabling or authorising stocks —— strikes with the army tactical missile systems within russia. the reason they were cautious about this and have been cautious about all the support they gave to ukraine since february 2022 has been a very wise fear of escalation, either leading to a bigger conflict with nato itself or possibly even employment of tactical nuclear weapons. even employment of tactical nuclearweapons. i even employment of tactical nuclear weapons. i think the reason they felt a little more confident, and let's be clear, it is an escalator decision, making it now is because they are confident when donald trump

takes office he will reverse it, so instead of giving ukrainians license to use these indefinitely, i think they are is —— are assuming it will be seen by near purton as licence for two months.— for two months. let's put this in the context _ for two months. let's put this in the context that _ for two months. let's put this in the context that president | in the context that president biden is in rio with g20 leaders, the last summit of this year. xijinping is leaders, the last summit of this year. xi jinping is there among other leaders and both the uk prime minister and joe biden have been saying they will try to garner support for ukraine while they are with world leaders. we have not heard an official line from president vladimir putin. what you think might happen next? he has you think might happen next? he: has previously made strong, unspecified threats about what would happen ifjoe biden authorised the strikes and said he would consider it as if nato itself was at war with russia

because now nato would be providing weapons systems that are striking within russia. i think it remains to be seen whether he will wait it out since he knows he will probably get favourable terms under donald trump, but i think we should note there are a range of escalator responses he has it is disposable that he is not used yet that he could still do short of provoking war with nato and i think recently he has threatened or intimated he might attack undersea fibre—optic cables that are responsible for the vast majority of data transfer between the us and europe, there are still undersea gas pipelines, additional hacking or sabotage operations, the option to increase the use of chemical weapons within ukraine, so i think there are a lot of responses that he could still use, unfortunately. irate still use, unfortunately. we are out of— still use, unfortunately. we

are out of time, _ still use, unfortunately. we are out of time, but thank you for your thoughts and analysis in response to that story. we will bring you as well here on bbc news more detail later about that g20 summit. officials in gaza say israeli air strikes killed at least a0 people on sunday after a strike on an apartment building in the town of beit lahia. israel said it was targeting hamas. and in lebanon, hezbollah says its media chief is dead after an israeli air strike in the centre of the capital, beirut. mohammed afif was one of the few remaining public faces of the group, whose leadership has been wiped out in a series of israeli attacks. with me is our bbc arabic correspondent said shehata. nice to see you. let's start with mohammed afif. tell us more about him and what it means for hezbollah that he has been killed. means for hezbollah that he has been killed-—

so inaudible another one inaudible supposed to be the successor, hassan nasrallah came to be inaudible many lines so the structure of hezbollah will mean it will carry on. it will mean it will carry on. it will weaken them but it will not be the end of hezbollah. let's talk about the sunday attacks in northern gaza. what can ou attacks in northern gaza. what can you tell us? _ attacks in northern gaza. what can you tell us? it _ attacks in northern gaza. what can you tell us? it was - attacks in northern gaza. what can you tell us? it was an - attacks in northern gaza. what can you tell us? it was an air. can you tell us? it was an air strike ona can you tell us? it was an air strike on a building in gaza. there were more than a0 killed according to the civil defence and health ministry in gaza. they were, according to the israelis, targeting israelis inaudible airforce, israelis, targeting israelis inaudible air force, security and all the troops they could not get rid of the fighters. they came from the tunnels, the tunnels are still working, so devastating to the humanitarian

the prime minister, sir keir starmer, will meet with the chinese leader, xi jinping, on the sidelines of the summit on monday. it will mark the first time in more than six years that a british prime minister has met president xi. for a preview of what leaders are hoping to achieve, here's our diplomatic correspondent james landale, who is in rio dejaneiro. this is a summit of the worlds most powerful countries with the biggest economies representing about 85% of global wealth, 75% of global trade. president xi of china will be here, prior mr moodie of india will be here and the brazilian hosts have a packed agenda wanted to talk about plans to tackle poverty and hunger, want to boost climate finance, want to discuss reform of international institutions, but the expectation is amongst diplomats this summit will be overshadowed by the i—man who is not coming and that is president—elect donald trump.

people are trying to scratch their heads to work out what he may do — trigger an international trade war by imposing tariffs on goods entering the united states? will give the israelis a freer hand to prosecute their war against and its proxies? will he try to force an end to the war in ukraine benefits russia? whiley escalate tensions between the us and china? much will depend on how world leaders here respond. —— will he. will they try to plan for what is coming down the line in january or will there be one or two rabbits frozen in the headlights? the un secretary general says we live in tumultuous times and is calling on g7 leaders to lead. we will hear more from him as the g7 progresses. the leaders, we're looking at countries covering

85% of the global economy, three quarters of world trade. it has huge implications for business. we will look at that later in business today. around the world and across the uk, this is bbc news.

joe biden has become the first sitting us president to visit the amazon rainforest. the trip, which came ahead his arrival at the g20 summit, was used by the outgoing president to pledge an additional $50 million to the amazon conservation fund, bringing the total us commitment to more than $100 million. speaking in the city of manaus, mr biden warned against the dangers of global warning. it is true. some may see to deny or — it is true. some may see to deny or delay _ it is true. some may see to deny or delay the _ it is true. some may see to deny or delay the clean - it is true. some may see to i deny or delay the clean energy revolution under way in america but nobody, nobody can reverse it, nobody. not when so many

people, regardless of party politics, i enjoying its benefits. not when countries around the world are harnessing the clean energy revolution to pull ahead themselves. the question now is, which government will stand in the way and which will seize the enormous economic opportunity? 0ur bbc brazil reporter, camilla mota, has more on how the us pledge has been received in brazil. it is symbolic, the only leader before joe it is symbolic, the only leader beforejoe biden was president roosevelt. it is symbolic but i would say the feeling here is that biden�*s visit is a little bit too little, too late, given that he is an outgoing president, i'd say that there is a bit of frustration among

brazilian authorities regarding what biden promised to the amazon region and what was actually done. it is farfrom it is far from the 500 million that was pledged to when ludo met with him. -- lula. scientists working to tackle climate change, say new technology to capture carbon, may be needed in the future, to help slow the rising rate of global temperatures. their solutions have so far been shown to work at a small scale, but they would need massive investment to make a meaningful difference. richard bilton reports. of the coast of north carolina an experiment that might help us all. ~ ., an experiment that might help us all. ~ . ., ., ., us all. we are heading out now and this is _ us all. we are heading out now and this is an _ us all. we are heading out now and this is an impervious - and this is an impervious vehicle so they will drive safe in —— straight into the surf.

such brave parents with a very important message. i will see you injust a moment. hello there. it might be time to break out the winter wardrobe over the next few days. we are heading for a cold spell. as the air comes all the way down from the arctic, it will increase the risk of some snow and ice, and certainly some widespread overnight frost, particularly into the early hours of wednesday morning. the cold air not quite arriving to all, still relatively mild down in the southwest, but a bitterly cold start in sheltered western rural parts of scotland — temperatures way below freezing and perhaps even some freezing fog as well. but generally scotland, northern ireland, northern england and north wales will keep some sunshine clouding over from the southwest later on in the day, with outbreaks of showery rain here. we mightjust see double digits

down across cornwall, but generally 6—9 degrees across england and wales. much colder further north — 3 or a. so the cold air is starting to push its way steadily southwards. but as this weather front moves in and bumps into that cold air, we could see the spell of significant snow — mostly to higher ground, but perhaps some accumulations at lower levels across parts of north wales, into the north midlands, up across the pennines, perhaps into southern scotland, as well as much as five to 10cm of snowfall before that low starts to pull away. and even once it does, it could turn quite icy behind, with a wintry mix of rain, sleet and snow across east anglia and south—east england for a time. windy with it as that low pulls away, and then we'll see a brisk northerly wind driving in some showers off north sea coasts. and here, they will be once again quite wintry. west will be best for sunshine on tuesday, but a cold day generally, with temperatures below where they should be for this time of year.

and factor in the strength of the wind, it will be a bit of a shock to the system, i suspect. the cold air sitting right across us, the isobars open up, so as we get into wednesday morning, we could see a widespread hard frost first thing. but there will be some lengthy spells of sunshine as well. a few more showers running down the west coast of scotland, down through the irish sea, perhaps, on wednesday, and those temperatures once again struggling — some areas just a couple of degrees above freezing. not much change as well as we move into thursday and friday. some of those showers could still be quite wintry.

live from london, this is business today. i'm sally bundock. we start in rio dejaneiro in brazil, where, as you've been hearing, global leaders are meeting today for this yea r�*s g20 summit. prime minister sir keir starmer has said he will be looking to use the forum to call on members to step up their support for ukraine. he is due a meeting with china's president xijingping on the sidelines. the prime minister is expected to be looking for areas of mutual cooperation, such as international stability and economic growth. the g20 summit comprises representatives from the world's most powerful countries, covering some 85% of the global economy and three quarters of the world's trade. hosts, brazil, have signposted their goals for the summit in fighting poverty and inequalit, and reforming global governance and global tax. but with the argentinian presidentjavier milei already objecting to some of this, and the uncertainty cast by the incoming trump administration in the us, concrete results may be hard to come by.
