we look at the impact. and forbes has revealed its latest world billionaires list. taylor swift ranks for the first time, along with the creator of chatgpt. voice-over: live from our studio in singapore, - this is bbc news. it's newsday. hello and welcome to the programme. we start in the middle east and the us has expressed outrage over the israeli strike that killed seven aid workers travelling in a convoy in gaza, including a dual american citizen and three britons. the white housejoined calls demanding israel do more to protect those providing support for palestinians in gaza, who are at risk of famine. earlier, isreali prime minister benjamin netanyahu said

the killings were unintended and tragic, but that such things happen in war. from jerusalem, our correspondent, lucy williamson, reports. hey, this is zomi. we're at the deir al—balah kitchen. they came from australia, poland, the us and the uk. their mission — to feed people — one of the simplest. in gaza — one of the hardest. and most dangerous. last night, israeli airstrikes hit their convoy, clearly marked with the charity logo of the world central kitchen. seven people killed, including three british nationals. colleagues, distraught, identified their bodies. "these are the people who brought the aid from the sea", he says. "they're all dead, all of them."

the workers had been unloading a second shipment of aid brought into gaza by sea. translation: it was a direct hit. their vehicles more than a mile apart. they tried to treat some of them and put them in another car in front, but they shelled the car. this is the situation here. anyone who brings aid to gaza is at risk of shelling and death. the remains of the convoy tell the story. three vehicles, each struck separately. one straight through the logo that was meant to protect them. a sustained and targeted attack. translation: unfortunately, in the past day, there - was a tragic event in which our forces unintentionally harmed non—combatants in the gaza strip. this happens in war. we are conducting a thorough inquiry and we are in contact with the governments. we will do everything to prevent a recurrence. six months into this war, the questions around the killing of civilians are getting sharper.

this was a clearly marked aid convoy passing through an area without heavy fighting under israeli control. aid agencies say co—ordinating safe passage with the israeli army in gaza is cumbersome and time—consuming. but it's this kind of event that it's designed to avoid. the un here says it's been warning about something like this for months. we have got people in these i very, very dangerous situations moving around without any comms between the different _ groups or different teams. and then, you know, i last night, for example, there was telephone calls coming from the world i central kitchen trying to make connectionsl and itjust wasn't possible. so you're moving around gaza, no communication between teams. why not? well, because the israelis say we shouldn't have - communications equipment because, if they do, - they could actually be taken i by hamas and used by hamas. i think it's a poor excuse. the first of the victims was buried today — a local man called saif abu taha.

gaza, already a byword for grief, is tonight mourning those who came to save lives and paid with their own. lucy williamson, bbc news, jerusalem. shazia arshad is from the international aid agency islamic relief uk. this attack is is devastating. and for us, itjust heightens the worry that we have about our team on the ground in gaza. we've been warning that gaza is now become one of the world's most dangerous places to deliver aid. our teams themselves have been displaced. they've been trying to deliver aid for six months now, and they are finding that situation ever more difficult to do so as as the bombardment continues and without a cease fire in place. well, world central kitchen have announced that they will be suspending their operations in gaza. are you considering doing the same? our teams have been

on the ground for many years. they're local teams and we're going to continue working there as much as we can with our local partners. but the reality is that operations in gaza are very, very difficult. delivering aid safely has become not impossible. —— now impossible. and what we're seeing is the kind of complete erosion of any kind of operations for safe any safe operations. and really, what we need to see is we need to see aid getting in quickly, but we also need to see it being distributed safely. and that can't happen without a ceasefire. so we need that ceasefire to come in as quickly as possible so that our teams can do theirjobs. well, we still don't seem like we're any closer to having a ceasefire. and with aid agencies that like yourselves and world food kitchen now saying they're suspending operations, the humanitarian situation seems like it can only get worse from here. i mean, the humanitarian situation is already dire.

you know, we're talking about over the last few weeks, we've been talking about the risk of famine being imminent. and what that means is aid agencies like ours and like many of our colleagues across gaza need to be able to deliver aid. they need to be able to get food in. but if they can't do that safely, it's just not going to be viable. and then ultimately that's going to put civilians at risk, at greater risk of famine. people are already starving to death. and what we really need now is for aid to get in quickly and to be able to be distributed safely. our teams have already told us many stories of how difficult it is to operate under the current conditions. we need that situation to be remedied as quickly as possible so that they can provide the much, much desperately needed aid. could could you elaborate a bit on that about what your teams are facing on the ground? i mean, our teams have been working in gaza since 1997, but over the last six months they have been talking to us about the very real difficulties that

they've been facing. they themselves have been displaced. they've been having to move further south across gaza. very, very early on in the beginning of the bombardment, there was actually a distribution taking place and very close within two blocks of the distribution taking place. there was a bombardment that went off, which was captured on video. and thatjust, to to all of us and to our teams, highlighted the very real risk that our teams are facing when they're having to conduct those distributions. it puts not only our teams at risk but, of course, the civilians who are also trying to get hold of that aid. shazia arshad is from the international aid agency islamic relief uk. the us and chinese presidents have had what both sides called a candid phone conversation, their first since meeting face—to—face in november. the call lasted almost two hours, with readouts saying the leaders candidly put forward their views on taiwan, us tech restrictions,

the ownership of tiktok, and beijing's support for russia. our north america correspondent, helena humprey, in washington, gave us more details. this more significant coming is the first conversation between two leaders since that moment in san francisco in november, at a time when relations between china and the united states were particularly frosty. it is particular phone call in some cases they picked up where they left off when it comes to cooperation agreements on artificial intelligence, climate change, restoring military to military cooperation so we don't see it military misunderstanding, tip into something more serious, also in terms of tamping down on

imports of precursor chemicals used to spend it all.. we know here in the united states to devastating effect. we can see their readout from the two presidents when it comes to those difficult issues both of them broached taiwan and economic issues. on the issue of taiwan president biden called for peace and stability at a time of increasing tensions in the taiwan strait and the south china sea. present xi said that any us interference in that area would be considered a red line by beijing. recent us sanctions especially tech companies saying this was a bid by washington to thwart the economy come athwart the development of high—tech industry. i think overall this conversation didn't really change anything between the two countries. butjohn kerby, national security spokesperson, had said it was constructive as well as being candid. we could see certainly those lines of communication appear open. we know there will be visits from us secretary of state antony blinken and

the treasury secretary janet yellen. also to reassure the global community at a time when it can ill afford any further conflict. the headlines: the turkish authorities say a fire at a nightclub undergoing renovation has killed 29 people in istanbul. the club is in the basement of a i6—storey building. police are yet to establish what caused the blaze. eight people, including the nightclub manager and a person responsible for the renovations, have had warrants out for their arrest in connection with the fire. one child has been killed in a school shooting in finland and two others were seriously injured. the victims and the suspected shooter are 12 years old. children under the age of 15 are not criminally liable in finland, so the suspect has not been remanded in custody and will be placed in the care of social services after further questioning.

russia says it's working on removing the taliban from its list of banned terrorist organisations. the kremlin spokesman said russia had to resolve pressing issues with nearby afghanistan. washington says it has evidence it was islamic state's afghan branch that was responsible for the deadly moscow concert hall attack 10 days ago. ukraine says it has carried out a drone strike on russia more than 1,300 kilometres from the border. it's thought they are the deepest into russian territory since the start of the war. at least 14 people were injured. sarah rainsford is in kyiv with the latest in the change of tactics. i think it is changing because this was a strike

on a site that russia must have thought was well out of ukrainian range. that's where it chose to build a giant factory to make the kamikaze drones that russia uses often in its attacks on ukraine. but that's where ukrainian drones managed to fly hundreds of miles into russia itself, undetected, and to reach that site. now, there is a video that has been posted on social media that shows one of those drones looking very much like a light aircraft and it's hurtling towards a building and it explodes there on impact. and there was another attack, too, a drone attack on an oil refinery in the same area. now, in kyiv tonight, ukrainian intelligence officials have told us that they carried out those attacks and they've talked about significant damage. but there isn't actually any evidence of the drone production facility itself being damaged. so far, the only videos coming out of russia have shown damage to a hostel, a student hostel across the road. but i think it is still clear that ukraine is significantly increasing its capacity in terms of drone production. and that's happening at a time when ukraine's western allies, of course, are stalling

on providing ammunition and they are shying away from providing long—range missiles. so ukraine is really focused on its drone production at the moment, particularly long—range drones. and president zelensky has talked about the need to ramp up that production, particularly against what he calls special tasks. so long—range drones for special tasks. and there was another reminder tonight why all of this is happening. another russian missile strike on an eastern ukrainian city. stu d e nts students for running for, and to a bomb shelter. staying with ukraine: nearly a year since it was passed in parliament, president zelensky has signed into law a bill lowering the draft age by two years to 25. mobilisation has become a divisive issue in ukraine, exhausted by two years of war and heavy losses. russia enjoys a massive advantage in manpower,

and mr zelensky said in december the army wanted to mobilise up to 500,000 people to battle moscow's forces in ukraine. the army enlistment system is considered by many ukrainians to be unjust, inefficient and often corrupt. around the world and across the uk, this is bbc news.

welcome back. the russian ambassador at the us and a security council meeting that is�*s actions reflected its blatant disregard

for ceasefire demands. earlier the un secretary general antonio guterres warned that any miscalculation could lead to a broader conflict in an already volatile region. israel has made no comment. he gave me his view on whether this feels like a dangerous moment. i this feels like a dangerous moment-— this feels like a dangerous moment. ~' ., ., moment. i think the iranian leadership _ moment. i think the iranian leadership probably - moment. i think the iranian . leadership probably would take their time. leadership probably would take theirtime. if leadership probably would take their time. if we go on the basis of their past actions, they do not react immediately and therefore their response will be very calculated and perhaps at appropriate time. we know that general soleimani was

sedated, they promised they would response but it took quite a while for them, perhaps the response attacking mossad headquarters in northern iraq last year and of course using their affiliates, whether they are in lebanon or syria or iraq or yemen to act indirectly rather than directly. i don't expect an immediate response from the iranians but at the same time they will be considering some actions just for their own reasons and international standing and in relation to their domestic politics. relation to their domestic olitics. ., , . ., politics. on domestic politics, the iranian — politics. on domestic politics, the iranian leadership - politics. on domestic politics, the iranian leadership has - the iranian leadership has promised a decisive response. we've seen protests in iran and we know the senior military

officials are unhappy with what happened. they are under pressure to respond, aren't they? pressure to respond, aren't the ? , ., ., they? they are about the same time they _ they? they are about the same time they don't _ they? they are about the same time they don't want _ they? they are about the same time they don't want to - they? they are about the same time they don't want to get - time they don't want to get into a direct war with israel which would also bring united states interaction. from the iranian perspective, israel is doing everything possible to draw iran into a regional conflict so that the united states can come support israel. and of course the israeli leadership has that more than once that they want to get rid of all threats to israel, not only from hamas would also hezbollah in lebanon and iranpresence in syria and other iranian affiliations which have acted so far in solidarity. and hamas with the palestinian course.

well, china's leaders are trying to find ways to battle what many economists have described as a demographic ticking time bomb. the country is ageing and shrinking — one in five people are over the age of 60 — which is the largest elderly population in the world. pension and healthcare systems are struggling to cope at a time when women are having fewer babies. so, can china afford to grow old? our china correspondent, laura bicker, has been finding out. this generation witnessed the birth of communist china. but while some are ending their lives in comfort, many still have to work until they drop. huh? 0k. i will follow you. grandma feng shows me her room in an elderly care home. you've got a little balcony out the front. she's decided to pay for long—term care rather than rely on her son. translation: i'm. more open-minded. there are few people of the same age who think like us, and it seems we care more about enjoying life. but i thought it through.

i gave my house to my son. all we need is our two pension cards. this home is touted as a model for china's future. young people also live here, rent—free as volunteer caters. and while it's great for residents, it's not so great for profit margins. private companies have invested in this home, but it's currently running at a loss. so beijing does need other ideas. these glamorous grannies in the city of hangzhou have found a new career in retirement as models and social media stars, and they promote greying gracefully. china hopes more over—60s will continue working as the economy slows. i think that is the right time, especially for us,

because i believe i am one of the generation that really benefit from the country's reform and open toward a policy. then maybe it is our obligation also to promote our image to the world. that image belies the harsh reality for millions in china. this couple in the rural north—east have no pension. they can't afford to stop working or get sick. translation: i guess i will become - a burden for my children. they will need i to look after me. i'm 72 this year. i think i can only keep doing thisl for another four or five years. but if feeble and weak, then i might be confined to bed. i that's it. over. ordinary people like us all end up like this. -

like much of rural china, there are few young people left to look after the old, especially after decades of a policy allowing couples to have just one child. the rising ranks of the elderly are causing a dramatic imbalance, which threatens the future of the world's second largest economy. it means china may grow old before it gets rich. laura bicker, bbc news, liaoning province. breaking news. an earthquake with a prominent manager of 7.5 struggle of southwest japan. the warning has been issued for the coastal area near the southern prefecture of. an eyewitness told reuters it was felt in taipei as well with some power outages. we have more of the story as it develops and we receive information. now to other news.

in fact, in east anglia, we could see a high of 20 celsius — 68 fahrenheit — way above the average for this time of year in that area. bearthat in mind, but we are all starting to be aware that a warmer atmosphere means a wetter one, and you can see these areas of low pressure waiting in the wings to influence the weather story. so the first low is moving through on wednesday, bringing rain into northern ireland, southern scotland. behind it, there'll be a few sharp showers to come, as well, so by the middle part of the afternoon, expect some sunny spells, perhaps more than we saw on tuesday, and temperatures will peak at highs of 15 celsius. some of the showers across northern england, though, could still be quite heavy, and that showery rain will start to drift out of northern ireland, improving here into central scotland. the far north and east of scotland will stay largely fine and dry, with some showers, but a north—easterly wind will make it feel noticeably colder, temperatures a good ten degrees down on where they are further south. so that low pulls away, another one is going to replace it on thursday, and then another significant low waiting

in the wings for the start of the weekend. so on thursday, as that cloud and rain pushes its way steadily north through the night, it will be a mild start to thursday morning. we'll see showery outbreaks of rain pushing their way steadily eastwards throughout the day, so hopefully a slow improvement. but here's the next system already starting to show its hand across cornwall and south wales by the end of the day. ahead of it, with some brightness, we'll see highs of 16 degrees. but that north—easterly wind once again pegging those temperatures back — in aberdeenshire, a high ofjust16. then, as we move towards the end of the week, this low could bring some very windy weatherfor a time, gales on exposed coasts, a spell of heavy rain moving its way steadily north, and it's this that will tap into that pretty mild air all the way down from the south—west, starting to push its way across scotland now, as well. but don't expect anything prolonged, settled and sunny. there will continue to be showers, longer spells of rain. windy but warm.
