in america and around the globe. already on the frontline of climate change, somalia is enduring its worst drought in a0 years. and the presence of one of the deadliest islamist extremist groups, al shabab, complicates the distribution ofaid. the united nations is warning that half a million children under the age of five are at risk of dying by the middle of next year. somalia urgently needs another billion dollars in humanitarian aid. six weeks ago we brought you andrew harding's first report from the town of baidoa — he's now returned there, to the heart of the crisis, and a warning, you may find some of the images in his report distressing. we're tearing through baidoa. our guard is driving faster than on our last visit. the threat of ambushes by islamist militants is growing here. suddenly, we stumble across a funeral, for a six—year—old boy who starved

to death yesterday. 11 more children were buried here this week. but it's one particular family that's drawn us back to a desolate camp on the edge of town. fatouma mohamed is heating breakfast for her children — a cup of tea. they will eat late in the day. nice to see you again. we have returned to see how the family is coping. hi, dahir. this was dahir here six weeks ago, mourning his younger brother salat, who died of hunger on the journey into baidoa. today, he's in good spirits. she's feeling hot? but his two sisters are now struggling. they have suspected measles. perhaps pneumonia, too. the illnesses that seem to feast on hunger.

and which lead so often to this. in a nearby hospital, this two—year—old looks like a burn victim. in fact, her body is reacting, painfully, to prolonged starvation. as on our visit last month, the ward here is still full of such cases. does it feel to you like the world is paying attention now to somalia? now we can say that the attention of the international community is on somalia, especially the droughts here. so, you are getting more aid because of that? we are not getting enough, but we hope it will come soon. it's a desperate situation. back at the camp, 11—year—old dahir is heading to school. he's bright, alert. our presence might be part of that but around him —

listless children and a chorus of coughing. the teacher tells us that most of his class struggle to attend or to focus. many here will be stunted for life. across the road a sudden crowd. a mood of near panic as frustrated mothers try to register for new food hand—outs, but there is not enough. it's overwhelming. we are not getting the resources on time with adequate amounts. you're only getting half what you need, is that right? that is exactly the right picture, we are getting half of what we want. later in the day, fatouma hauls water home for her children. dahir here is quick to help out. "i'm getting by," she says, "but my children are not well. "i must work to make sure they survive."

coughing somalia is struggling right now, but it is worth remembering that before this last drought, dahir and his family were doing 0k. they had fields and crops and six cows and some goats. they were middleclass farmers. suddenly, left destitute, bankrupted, by drought, by climate change. inside their hut, the girls slump. do you worry about yoursisters, dahir? he says yes, he does. what do you worry about? we are straying here towards painful memories of dahir�*s brother. "i just want my sisters to get better." he says it three times. coughing. an exhausted fatouma joins her daughters on their blanket. one family in a nation

still overwhelmed by hunger. andrew harding, bbc news, somalia. the 620 summit is under way in bali and leaders of the world's largest economies will be making plans for the global economy. 0ur correspondent karishma vaswani is there. there has been so much to discuss at the summit in bali that officially got under way today and one of the key focuses today in fact is food security. timely given the reporting we have just seen from andrew harding over that situation getting worse in somalia. it is a similar concern here in bali with leaders of the top 20 economies looking at things like food security as well as the energy transition that they are hoping to make from dirty fuel to more

clean forms of fuel, a key aspect of their economy. another key focus has been the relationship between china and the united states. we saw a meeting between the presidents of those two countries face—to—face for the first time since joe face—to—face for the first time sincejoe biden took office and they discussed a range of issues, i must say. everything from the sensitive topic of taiwan to the use of nuclear weapons. my colleague, sarah smith, has more. president biden looks eager to meet again with a man he always says he knows well. this is his first face—to—face with president xi as leaders of their nations, but they spent many hours together when they were both vice presidents — hence the relaxed body language and maybe even a cooperative mood, despite relations between their countries being at their worst for decades. there is much to discuss, from economy, trade and climate change, to human rights, the war in ukraine and

of course taiwan. no wonder the meeting lasted for over three hours. as leaders of our two nations, we share responsibility in my view to show that china and the united states can manage our differences, prevent competition from becoming anything anywhere near conflict. they agreed — nuclear weapons must not be used or even threatened by russia in ukraine. the biggest problem is taiwan. president xi called it the first red line america must not cross. the recent visit by the senior us politician, nancy pelosi, to the democratic self—governing island enraged beijing. china responded with military exercises around the island. president biden today warned his chinese counterpart against trying to change the island's status, but also told him the us has not changed its policy which acknowledges taiwan is part of china. after today's meeting, he said he does not think there will be an imminent attempt to invade taiwan.

we're going to compete vigorously, but i'm not looking for conflict, i'm looking to manage this competition responsibly. and i want to make sure, make sure that every country abides by the international rules of the road. i absolutely believe there need not be a new cold war. there was never an expectation of any binding deals coming out of today's meeting. instead, it was an attempt to lower the temperature, with each country setting out what it will not tolerate from the other in the hope of preventing disagreement turning into conflict and to try to avoid a new cold war. sarah smith, bbc news. sarah was talking about the avoidance of a new cold war but another topic that has been very important here at the g20 is the war in ukraine. we have been hearing, in fact, or rather the g20 has been hearing

from the president of ukraine who addressed delegates and leaders via video link, according to the afp news agency, he is calling for an end to the war and saying that was time to end russia's destructive war and save thousands of lives. he did not appear physically in person, he addressed the group virtually but it is is consistently been a theme in the back drop against the summit, that conflict in ukraine and something that i spoke to kevin rudd, the former australian prime minister about as well. well, going back to the origins of the g20 itself, of which i was the co—founder in 2008—09, the useful thing about the meeting in indonesia is that it brings together heads of government, who have contrasting views. absent the g20, would they currently be meeting? that is a

difficult question. on this question of russia's invasion of ukraine, on the substance of what you've just said, i imagine that basically the 67+ will issue a combined statement on its position of total opposition to russia's continued brutal invasion of ukraine, but there will be some of course distancing from that. china will not sign onto such a statement and of course indonesia itself plus india may have a different view as well. but this is par for the course at summits of this nature. i think sergei lavrov will be surprised by the level of solidarity across much of the democratic world over what his country has just done in ukraine. absolutely, and as you point out the war in ukraine really dominating the agenda. one of the key issues that countries will be

discussing today is food security and how the blockade of grain exports from that region is really affecting globalfood prices. do you see any sort of concrete action coming from this meeting orjust meaningful rhetoric rather than actual action that they can put in place? i think as we approach the geopolitics of this g20 summit, there are two big questions on the agenda. one is what we have just discussed which is russia ukraine and its impact on global stability, plus commodity prices, oil, gas, and of course agriculture. the second big one, though, is the stabilisation of us—china relations and for those countries of the indo—pacific, that is a larger question. the g20 will be dealing with both. as for any breakthrough on the grain question, the success of that i think will hinge on frankly turkey's continuing diplomacy, as an intermediary in terms of arrangements in the black sea, in order

to facilitate ukrainian continued grain exports, despite russia's episodic hostility for the continuation. that was kevin rudd, the former australian prime minister speaking to me earlier about the fact that there has been a suggestion, a statement released by some countries here at the g20 condemning russia's actions in ukraine. figs at the 620 condemning russia's actions in ukraine.— actions in ukraine. as mr rod has pointed — actions in ukraine. as mr rod has pointed out _ actions in ukraine. as mr rod has pointed out it _ actions in ukraine. as mr rod has pointed out it is - has pointed out it is potentially quite a diplomatic issue even the fact that we may not see all of the g20 nations sign onto a of that strength. interesting that we did here earlier from the host of the 620, the earlier from the host of the g20, the indonesian president, saying that there must be an end to this war in rather strong language that we heard from him on the conflict in ukraine. for now, that is it from me and the team in bali. back to the studio in london.

let's get some of the day's other news. the director of the cia has met the head of russia's foreign intelligence service in the turkish capital, ankara. the white house said william burns spoke about the consequences of using nuclear weapons, and the risk of escalation, adding that it was not conducting negotiations of any kind, and not discussing a settlement to end the war in ukraine. kurdish groups in turkey and syria have denied being behind a bomb attack that killed six people in istanbul on sunday. two organisations — the pkk and the sdf — said they didn't play any role in the explosion, which happened on a busy shopping street. the turkish authorities say kurdish miltants were to blame. police have arrested the woman suspected of planting a bomb. the american comedian, jay leno, has said he's 0k after being burned in a fire. the 72—year—old was taken to hospital on sunday after one of his cars burst into flames inside his garage. the former talk show host said he'd suffered serious burns, but was now

shopping areas, lights displays are being switched off, air conditioning is being turned down, and governments are calling for restricted energy use in the face of soaring costs. tom brada reports. with christmas fast approaching, department stores are showing off their festive displays. but this trading system is not a straightforward one. inflation and rising energy costs mean retailers have a delicate balancing act to perform. keeping costs at a level they can manage while still offering that sparkle which can pull the punters in. translation: we have to use less energy, less electricity and fewer illuminations, but at the same time, we, deprive prescience, children and visitors are tourists alike of a moment of shared collective jov- a moment of shared collective 'o . ,, ., ., a moment of shared collective 'o. .,., , joy. similar targets are being set in london. _ joy. similar targets are being set in london. even - joy. similar targets are being set in london. even harrods, department store synonymous with wealth and luxury, is making compromises. you will turn down _ making compromises. you will turn down the _ making compromises. you will turn down the lights _ making compromises. you will turn down the lights in - making compromises. you will

kari lake, a high—profile supporter of donald trump and denier of the 2020 election result. arizona is regarded as a battleground state and is expected to play an important role in the next presidential electon in 202a. our north america correspondent peter bowes joins us from los angeles. peter, this is a significant result. how significant is it? potentially, this is hugely significant. this is one of the closest watched races in the country, largely because of kari lake, because she is a well—known figure in the states, she has been an evening news presenter, she has been very critical of the mainstream media, suggesting that it favours the democrats. he is very close to donald trump to the extent that some people have speculated that if donald trump launches another race for the presidency himself, that kari lake could potentially have been his running mate.

they were very close over that crucial 2020 election, agreeing on those false claims that there was skullduggery going on during the election result in the denial ofjoe biden�*s wins. now this makes all the difference when katie hobbs, who as a secretary of state in arizona's job who as a secretary of state in arizona'sjob it who as a secretary of state in arizona's job it was to oversee the 2020 election, and she has pushed back on any claims that there was any wrongdoing in 2020. ., ., 2020. you mentioned there if donald trump _ 2020. you mentioned there if donald trump announces - 2020. you mentioned there if donald trump announces he l 2020. you mentioned there if. donald trump announces he will run in 2024, he has long been saying tuesday the 15th is the day he will make a major announcement. that is a matter of hours away. any idea if he will change his mind now to well, if he is, we don't know. it would certainly be very out of character for donald trump i think to change his mind in a big way. some people say that he believes it will be a sign of weakness were he not to announce this week that he is

standing once again for the third time for the presidency. but being donald trump, we won't actually know until he stands up and says what he is planning to say. what is certain, though, is it will likely upset many republicans. we have heard several voices, senior members of the party over the last few days suggesting that it would be absolutely the wrong thing for him to do in the wrong thing for the party, given the results of these mid—term elections. results of these mid-term elections-_ results of these mid-term elections. ., ~ , ., elections. peter, thank you so much. plenty more details on the situation in the us on our website. the bbc is celebrating the 100th anniversary of its first official broadcast, a news bulletin from london. our correspondent david sillito reports. hello. 2lo calling, 2lo calling. november 14, 1922, and the beginning of the bbc. 2lo was the call sign of the bbc station in london.

and 100 years on, the six o'clock radio news has been marking how it all began. bell tolls this bulletin marks the moment 100 years ago that the bbc began broadcasting. back in 1922, the newsreader at 6pm was arthur burrows. arthur burrows at this point is the first voice of the bbc. he's almost had the idea of broadcasting a few years earlier as well, and within a month, he'll be director of programmes at the bbc and one of ourfirst children's presenters. yes, arthur was also �*uncle arthur', children's entertainer. it wasn't a large organisation on day one. how many staff at the beginning, in november 1922? november 1922, the bbc has a staff of zero. there are no employees. there are no official staff? there are no official staff. arthur burrows does that first broadcast essentially in his spare time. was itjust london in november 1922? no, london was day one, and then day two was birmingham and manchester, and that's where you get musical concerts, children's programmes come in there,

the general election results as well, all mixed in together. singing and the bbc has only now been discovering just how many of its pioneering programmes came from manchester and birmingham. overto you, birmingham. it's adding details to its online radio times history about satire, concerts. and this is puppy from the children's programme from glasgow. but it began with the news and it was nerve—racking. arthur burrows later wrote he could think of no more exacting a test of physical fitness than the reading of a news bulletin. david sillito, bbc news. hgppy happy birthday to the bbc, although i do apologise for not wearing black tie for this bulletin 100 years on. loads more details on the g20 summit on a live page on our bbc news website. read more comments

from president zelensky, president putin taking part in person this year. that is all from us. for the moment, thank you for watching and there is much more to come in bbc news. hello there. on the whole, it was a relatively quiet start to our working week, but a change is on the way, and you can see that as we closed out the day in cornwall on monday with this blanket of cloud a bit like closing the curtains across the south—west and, yes, there's a weather front that's bringing some wet and windy weather. you can see the extent of the cloud on the satellite picture actually, and it's this frontal system tied in to an area of low pressure, which will continue to move further north and east. so, for the next few hours, be prepared for some heavy rain, but more importantly, some gale—force gusts of winds — gusts in excess of 50—60mph as that rain continues to push its way steadily north and east. so, first thing in the morning, the rain heaviest perhaps

across parts of dorset, moving up through hampshire. then that's going to drift its way steadily northwards through the east wales, into the midlands, to north—west england, and eventually, it'll push its way steadily north and east. there will be quite a clearance behind to some sunshine and a scattering of sharp, blustery showers in the far south—west. the winds will be a feature, but the strongest gusts still with that rain, so gusts in excess of 55mph plus in the northern isles as that rain pushes its way steadily northwards. temperatures, 11 to 14 degrees, about where they should be for the time of year, but obviously, it'll feel cooler with the cloud, the wind and the rain. so, the rain pushes its way steadily north, we'll see a cluster of showers through wednesday night across west and south—facing coasts, but where we do have some clearer skies, we'll see low single figures, so it could be a bit of a chilly start to our wednesday morning. on the whole, wednesday is a chance to get a little bit of a breather in. there will be some showers across the south and the west first thing, slowly improving

into the afternoon before the next system moves in, more wet and windy weather still yet to come. a cooler day, top temperatures between 10 and 13 celsius. now, it looks likely that we'll see another spell of wet and windy weather through the latter stages of wednesday into thursday before a little ridge of high pressure fills in behind — that's worth bearing in mind. so, all in all, as we close out this week, it looks likely that we will see another unsettled day on thursday, friday, the best of the dry weather, and it's probably a good opportunity to make the most of it. the weekend looks wet and windy once again.

a settlement to end the war in ukraine.

this is bbc news, the headlines: an international charity says the devastating drought in somalia has led to the biggest movement of refugees into kenya, in more than a decade. nearly 70,000 more are expected to arrive by april next year, as somalia edges closer to famine. the democratic candidate for governor in arizona, katie hobbs, has defeated her far—right, trump—backed opponent. democrat victories in arizona and nevada helped them retain control of the senate. counting is expected to continue for several more days before it's clear whether the republicans will win control of the house of representatives. world leaders are gathering in bali in indonesia for a summit of the g20 group of nations. high on the agenda —

the stability of the global economy, the energy crisis and how to address the ongoing
