near the gaza strip�*s southern border with egypt, trying to escape intense fighting elsewhere. the head of humanitarian affairs for the united nations says there is no longer any humanitarian operation worthy of that name in the south of gaza. meanwhile, aid agencies estimate nearly two million people have already been displaced — that's almost 80% of gaza's population. thousands have tried to go to un schools to find shelter, but have had to sleep in front of buildings as there is no room for them. and most of those are struggling to find safe water and food, deepening the humanitarian crisis as israel's military operation against hamas grinds on. for more on the aid situation, here's our diplomatic correspondent paul adams in jerusalem. the israeli army is now fighting intense street battles with three parts of the gaza strip, two in the north, in the jabalia refugee camp and gaza city known as shejaiya. both areas the israelis have described as hamas strongholds. also in the southern city of khan younis, the largest city in the southern gaza strip. and there, the fighting in the south is moving so quickly that the aid agencies, frankly, are not able to keep up. remember, this is an area where huge numbers of palestinians are sheltering, having been displaced from their homes elsewhere. we think that the bulk of the population of the entire gaza strip is huddled in the south with as many as 80%, according to the un, 80% of gaza's population now displaced by the fighting. this is creating a dire humanitarian situation, the agencies finding it difficult to get aid to where it is needed and there is frankly not enough aid. it's leading martin griffiths, the un's humanitarian chief, to conclude it really isn't an effective operation, humanitarian operation, at least one worth its name in the southern gaza strip. there are negotiations going on with israelis to try and add another facility to the processing of the aid trucks — around 200 can be processed a day, not nearly that many are getting in but if the process is to ramp up they will need additionalfacilities and the israelis have said the kerem shalom crossing could be used not for aid going into gaza but for a place to process the trucks that then go in via the rafah crossing which could make a difference and we are seeing people like the british defence secretary grant shapps who is here in the region talking about using royal navy ships to bring in aid by sea. so a lot of people are talking about how to relieve the situation but at the moment, there is no sign of any of these plans coming together in any remotely coherent way. our diplomatic correspondence there, paul adams. our diplomatic correspondence there, pauladams. we our diplomatic correspondence there, paul adams. we can take a look at pictures of the gaza strip now and take a look at that scene with the egyptian red crescent saying they are overcoming enormous logistical efforts to try to get aid into that area. tommaso della longa, the spokesperson for the international federation of red cross and red crescent societies, spoke to my colleague sumi somaskanda a little earlier. tomaso, the head of the un aid operation�*s martin griffiths said there is no longer a humanitarian operation in gaza that can be called by that name. do you agree with that assessment? well, i canjust echo his words. we've been saying this in the last weeks. of course, palestine red crescent colleagues are doing their utmost to support people in the whole gaza strip but the reality is the more the conflict goes on, the more the needs are growing and the less we are able to deliver because the capacity is very limited, access is a big issue, continuous flow of humanitarian aid is not there so, yeah, the humanitarian operation is very complicated and it is a great challenge at the moment. we know tens of thousands of palestinians right now are streaming into rafah to escape the fighting. can you give us an idea of what the situation is like there now? the situation, the reality that the people in gaza are living a desperate situation. i would say the worst nightmare. mainly, there is no safe space in the entire gaza strip and, of course, even if they want — i mean, you can say people want to go out from the rafah border, or at least very nearby the border so to use the first occasion possible to go out, it's impossible to go out so it's really the kind of sealed inside the gaza strip in a situation where there is no safety but even worse, there is no shelter, lack of food, lack of water, lack of access to as well. as a desperate situation and we do hope and we call on the parties, has been the same since the beginning, immediate access continues for humanitarian aid and of course respect the civilians and aid workers. your organisation has been coordinating aid, you have been coordinating it from cairo. can you give us an idea how difficult it has been to deliver that aid? of course, it's an enormous logistical challenge but i have to admit i'm just back from egypt and i was really inspired by the efforts of the colleagues of the egyptian red crescent. as you know, it's a leading agency bringing the entire humanitarian aid from egypt to gaza. at the moment, the rafah border is the only lifeline for the people in gaza. and of course, the big challenge, it's firstly to be able to bring all of the aid entering in different areas of egypt to the border. but then, the second challenge is also how to prepare for this kind of operation because we never know if one day we will be able to enter with trucks. the next day 200 trucks and the third probably with 20. and, of course, i told our red crescent colleagues on the gaza side, so it's really an incredible effort. the main problem is we cannot plan because in this kind of situation it's impossible planning and, even worse, is impossible planning when we will be able to reach the people in gaza. israel is saying now it will reopen in the coming days another crossing to gaza to inspect aid trucks, the kerem shalom crossing. do you think it will help provide relief? of course it will be a very important step. also this one we have been saying since the beginning. the problem here is to make sure there will be a continuous entrance of humanitarian flow and humanitarian aid and then the more that we can get humanitarian aid inside gaza, the better it is. then i have to say there is not enough to open a door, or a gate or a border. then we need also to create, together with the parties, a safe humanitarian space where we can operate but also civilians feel safe but to get the aid that they need. thank you for sharing your perspective with us, appreciat it. thank you. more than 360 people were murdered there. another a0 were taken hostage and there is concern that the scale of the psychological support needed is far greater than the state can provide. train volunteers are now setting up their own centres to try to offer that help. our correspondent went to visit one in respondent north of tel aviv where she met the psychologist who founded the project. ourapologies, psychologist who founded the project. our apologies, we do not appear to have that report for you. not appear to have that report foryou. but not appear to have that report for you. but we can move on to our next story. it is with regards to aid in ukraine, and turning to the country now and after two years of fighting, the situation with regards to us security aid for the country appears uncertain. speaking to a virtual meeting of the g7 leaders on wednesday, president volodymyr zelenskyy said ukraine risks losing against russia without further us support warning that russia is waiting for the west to show weakness. his plea comes after senate republicans blocked an emergency aid package to ukraine and israel after failing to secure border compromises they sought in exchange. presidentjoe biden had urged congress to "do the right thing" in pushing for more aid to ukraine. on thursday, the white house said the president is open to negotiating with republicans about funding but will not be dictated to by extremist factions within the party. as of october this year, the us has given the most funding for military aid to ukraine at $a6 billion. germany and the uk trail behind the us at second and third place. but the white house has warned that us funds for ukraine could soon run out. for more on this, i spoke to director of the critical threats project at the american enterprise institute, fred kagan. thank you forjoining us here on bbc news. as you know, senate republicans have blocked billions of dollars worth of security aid to ukraine. president biden was trying to break that impasse and said "we cannot let putin win." without more aid, a realistic prospect? ——how realistic is that prospect. if the united states does not give ukraine any more aid at all, then the likelihood is very high that putin will in fact win, notjust by holding what he has but also by driving further to the west and probably, ultimately, succeeding and subjugating all of ukraine. it is fair to say there seems to be some war fatigue setting in right now. we have events in the middle east and at the same time there is some discussion as to why that ukrainian counteroffensive did not achieve the results that of course many western allies were hoping for. i want to point to a recent washington post report that quoted an anonymous us special explaining that kyiv moved too late or listened too little. what you make of that? first of all, there may be war spending fatigue and war looking at fatigue, but there is not war fighting fatigue in the west, which is very important because the reason we need to continue to support ukraine is so we will not end up having to fight ourselves on behalf of nato against a victorious russian military. that is the first point. the second point on the counteroffensive, yes, there has been lots of blame thrown around. western officials have also acknowledged — and western leaders and militaries made errors. there are setbacks in war. this was a very difficult thing the ukrainians undertook to do. it was disappointing in its results but it is not dispositive. it has not brought us to the end of this conflict. talking about that progress and the blame game, as you put it, we also know western allies provided something of a slow drip of weapons to ukraine. do you think that was a mistake? i thought it was a mistake and i and my colleagues at the institute for the study of war have said that for some time. the west has been a day late and a weapon short throughout this war. the delays in getting ukraine's systems that was evident early on in the war that it would need lead to delays in the counteroffensive for which the ukrainians are now somewhat unjustly being blamed. what i'm more concerned about though is that we seem to be repeating the same mistake right now. because the delays in getting aid to ukraine now will also delay ukrainian operations in 202a. and i am very concerned that assuming that ultimately a good sense of self—interest does prevail in congress and in europe, and we get ukraine the aid that it needs soon, i am afraid that we will still be in a situation where ukrainian operations in 202a will be delayed and the russians will have additional opportunities to take advantage of that delay. fred, i just want to ask what you think could be a game changer in this conflict for ukraine. it is worth pointing out as well that ukrainian army has had nothing like the air defence capabilities other nato armies for example would employ this kind of scenario. what do they need in terms of weaponry to change the calculation? many others have said this and i can only echo, no nato commander, no nato leader would have ordered nato fortis to conduct a mechanised penetration and exploitation operation without air superiority, let alone in circumstances in which the adversary could use his aircraft against the mechanised force during the penetration. ukraine needs air power. it needs long—range strike. it needs a lot of tanks and armoured vehicles. it needs a lot of artillery. it needs all of the tools of modern warfare. so it can prosecute this war to a successful conclusion and set conditions thereby so that nato will not have to end up using nato troops and nato personel and later life to confront russia at a later date. we are of course in winter now. around the world and across the uk, this is bbc news. let's look at some of the stories making news in the uk. prime minister rishi sunak has urged mps to back his rwanda immigration plan after growing criticism from within his own party. mr sunak said his new legislation was the "toughest immigration law ever", and would finally allow deportation flights carrying illegal migrants to take off for east africa. borisjohnson told the uk covid inquiry that claims he didn't care about the suffering being inflicted on the country and wanted to let covid rip were simply not right. the former prime minister said he had experienced at first hand, during his time in intensive care, how appalling covid could be. mrjohnson was forced from office in disgrace last year over a series of scandals including being found to have broken his own covid lockdown rules. and tributes are continuing for benjamin zephaniah, one of britain's leading poets who's died at the age of 65. he was diagnosed with a brain tumourjust two months ago. he's been described as a once—in—a—generation poet, writer, musician and activist. you're live with bbc news. presidentjoe biden�*s son hunter faces new criminal charges in federal court in los angeles. federal prosecutors allege that hunter "engaged in a four—year scheme "to not pay at least $i.a million in federal income taxes "from 2016 until 2019." it's the second criminal case that special counsel david weiss has brought against hunter biden. the federal indictment includes nine charges — five of them for failure to file and pay taxes, one charge for evasion of assessment, two charges for filing a false or fraudulent tax return and the last charge is for failure to file and pay taxes. the justice department says if convicted, hunter could face a maximum of 17 years in prison. the white house has not commented on the charges. it's the second week of the cop28 climate summit. the first week saw a range of global policy commitments including the loss and damage fund for countries bearing the brunt of climate change and commitments to try and reduce carbon emissions from the food system. but the big question is if there will be an agreement to phase out fossilfuels. over to the bbc�*s carl nasman in dubai. carl, we are at the half way point of the summit. we know the un climate chief has urging countries to agree ambitious actions against global warming. how are things looking? well, week two is beginning with some momentum. you mentioned the big headline agreements according to some tallies, $57 billion as well in total pledges in week one. the focus for week two will be on trying to come up with the text of the final agreement. sci—fi negotiations in that space are not where they need to the focus today is on youth and children and to talk more about that we have the assistant secretary general and unicef deputy director. thank you for speaking with us. children often on the front lines of climate change, one of the most impacted groups. why is that?
