between sitting president biden and former president trump, one thing is for sure, with republican voters they feel that nothing has changed this past four years. the polling consistently of american puts emigration of the top two concerns. beaten usually only by the economy into the dramatically increased cost of living. it's a battle at the border today. the two men most likely to be running for us president are in two texan border hotspots, each hoping to persuade voters that they have the answer to cutting illegal immigration. the number of gazans killed since october the 7th tops 30,000 according to the hamas—led ministry of health. we have a special report into an incident overnight in which more than 100 people were killed. what is the state of the nation in russia two years after the war

in ukraine began and two weeks before the elections? well, vladmir putin spoke for two hours. we will look at what he said and didn't say. and it's our weekly deep dive into the world of artificial intelligence, including how events organisers used al to generate images of a fantastical willy wonka world, but the reality was anything but sweet. we begin in texas, where both presidentjoe biden and former president donald trump are visiting the us—mexico border. the pair locked in a high—stakes political duel on an issue which could ultimately decide this year's presidential election. joe biden is visiting a border city called brownsville. it's recently seen a drop in the number of people illegally crossing into the us. donald trump meanwhile is in eagle pass, the texas border town where republican governor greg abbott has defied the biden white house by using state national guard

soldiers to detain undocumented migrants and erect border barricades. mr trump spoke there a short time ago. nice weather, beautiful day, but a very dangerous border. we are going to take care of it, thank you. another care of it, thank you. beautiful day, says donald trump. another beautiful day, says donald trump. immigration is a live topic in the us heading into the election. a recent gallup survey saw 28% of americans named immigration as their top concern, beating out every other topic, including the economy and inflation. some 61% of americans in a monmouth survey listed illegal immigration as a "very serious problem", with a majority of respondents for the first time saying they support mr trump's proposal of building a us—mexico border wall. that border was crossed last year by 2.5 million undocumented migrants, an influx that has overwhelmed

processing facilities and pushed social services in major american cities to the brink. 0ur correspondent tom bateman filed this report from eagle pass, where authorities have been grappling with the issue. searching in the shadows along the route of the rio grande, we've joined a night patrol searching a favoured landing spot for people who have made a perilous journey to reach the us. this texas rancher says last month hundreds of people swam and waded onto his land here. and we trace one narrow path in a global wave of the displaced. there are clothes everywhere, signs of life. this is treacherous for people making their way into america. angele, seven months pregnant, crossed the rio grande yesterday at three a:m.. herjourney from honduras's most violent city gripped

by gang warfare began two years ago. translation: i was holding hands with another pregnant woman - when we cross the river. the water was very cold and we were afraid of being swept by currents. i was so relieved once we made it to the land. record numbers of people seen here last month have been crossing, driven by conflict and instability drawn by the postpandemicjobs gap in america. but in an angrily divided country, a broken system for dealing with immigration claims has become a major election issue. the town's former police chief told us the system is failing everyone. what's the situation? it's terrible. we need to get biden out. that's it. plain and simple. we need to get trump in there to be more forceful and let our border patrol

guys do theirjob. and trump's style proposals are on full show. the republican governor of texas has sent state troops to the river bank, he says, to deter migrants, although there are few signs of its longer term impact. we watched as state forces stopped to check federal patrol trucks. a challenge to mr biden's authority at the border. this border path is now on the campaign trail, and america's issue with immigration is set to be a decisive one in the race for the white house. tom bateman, bbc news eagle pass in texas. live to new york with political analyst brian stelter. hello, brian. 0f hello, brian. of all the issues to go head—to—head with donald trump on on the same day in the same state, illegal immigration is quite a challenge for the president. what is he thinking, what is a strategy they are? it he thinking, what is a strategy they are? , ., , . . are? it is the thorniest challenge president biden _ are? it is the thorniest challenge president biden faces _ are? it is the thorniest challenge president biden faces for - are? it is the thorniest challenge president biden faces for that . are? it is the thorniest challenge i president biden faces for that many members of his own party are aware

of this. i've spoken with democratic donors who say we've been telling biden privately he has to have an answer to these questions about migration. illegal immigration is a single biggest topic that fox news and other right—wing media, other pro trump media have focused on basically every day of the biden administration, every day since he was inaugurated. they believe it's the most important wedge issue that can benefit republicans. biden is hearing from democrats who wanted to take action in he is hearing republican rhetoric against him visiting today.— republican rhetoric against him visiting today. we've heard that rhetoric already _ visiting today. we've heard that rhetoric already today. - visiting today. we've heard that rhetoric already today. donald l visiting today. we've heard that - rhetoric already today. donald trump landing talking about a beautiful day, he's going to sort out the border problem. is it an easy win for donald trump? it’s border problem. is it an easy win for donald trump?— border problem. is it an easy win for donald trump? it's a win in some cases, in for donald trump? it's a win in some cases. in we've _ for donald trump? it's a win in some cases, in we've seen president - for donald trump? it's a win in some cases, in we've seen president being j cases, in we've seen president being a demagogue for migration in many years. during the 2016 campaign he made it a signature topic. there are arguments he didn't take as many actions in office as he promised and

he is at a disappointing record. at least to some of the hard right. this is something that he is going to pond on fox news tonight. i look at 24 to pond on fox news tonight. i look at 2a election this way, every day the subject is illegal immigration and trump has the advantage for the everyday the topic is something about abortion, reproductive rights and biden is the advantage. that's a big story also in texas with up i interviewed a woman who couldn't get an abortion was doing the state there is not tension between competing issues, the democrats believing there on the defence on migration. believing there on the defence on miaration. ~ �* , . ., . migration. we're expected to hear from both potential _ migration. we're expected to hear from both potential candidates - migration. we're expected to hear from both potential candidates forj from both potential candidates for the election this evening. is there anything that president biden can say to reclaim the narrative on this issue? i say to reclaim the narrative on this issue? ~' . , . issue? i think he has a strong argument _ issue? i think he has a strong argument he _ issue? i think he has a strong argument he offered - issue? i think he has a strong argument he offered a - issue? i think he has a strong argument he offered a deal . argument he offered a deal that democrats reach a bipartisan deal with some republicans for the people who wanted to provide funding for border security, to take steps to control migration. yet house republicans squashed a bill for the

trump's was a bill for the biden said all year long he had a plan but trump ruined it. the republicans ruined it. that is a strong argument. that's a factual argument to make on the campaign trail. the fact is that — to make on the campaign trail. the fact is that statistics are that illegal immigration has gone up massively since president biden has beenin massively since president biden has been in the white house. that is a huge problem. been in the white house. that is a huge problem-— huge problem. that's partly in the wake of covid-19 _ huge problem. that's partly in the wake of covid-19 after _ huge problem. that's partly in the wake of covid-19 after 2020 - huge problem. that's partly in the wake of covid-19 after 2020 when j huge problem. that's partly in the i wake of covid-19 after 2020 when it wake of covid—19 after 2020 when it was relatively little migration happening the numbers like when biden took office for the democrats say biden is also deporting many people in those numbers are spiteful that this is the story that even though fast our passkey this is largely driven by feelings. when i talk to voters about this is much more about emotions than antidotes then statistics without those antidotes are about people,

especially even in cities like new york who feel uncomfortable with the rate of migration under biden. those pesky facts. brian, thank you so much forjoining us. could you talk to you. we much for “oining us. could you talk to ou. ~ , ., , , . to you. we will be dropping in and out of texas _

translation: during this humanitarian operation at 4:16 am, a mob ambushed the aid trucks, bringing the convoy to a halt. as you can see in this video, the tanks that were there to secure the convoy sees the gazans being trampled and cautiously tries to disperse the mob with a few warning shots. when the hundreds became thousands and things got out, out of hand, the tank commander decided to retreat to avoid harm to the thousands of gazans that were there. no idf strike was conducted towards the aid convoy. they said we brought aid, but we paid for that aid with our blood." thousands had gathered in the pre—dawn darkness. they'd heard trucks were coming with aid. there were farmers, mechanics, our bbc cameraman, teachers, doctors. an israeli drone filmed people crowding the aid trucks. it is a striking depiction of human desperation. israel says most of the casualties were trampled or knocked over by trucks, as drivers tried to flee the chaos.

but the military also says its troops opened fire when a crowd posed a threat to soldiers. it isn't yet possible to clarify how many of the dead were shot, how many crushed. watch this man, crawling along the ground, away from the food convoy. hospitals in northern gaza say they treated many gunshot wounds. translation: after they | stopped shooting, we went back to get our aid. this survivor was shot and run over. translation: by the time i got flour and some canned goods and took it i down from the truck, they'd shot at us. they shot at me, and the truck driver left and ran over my leg. this incident comes on a day when gaza marks a reported 30,000 deaths since the war began overfour months ago. there is the dying that happens in the open and suddenly... ..and there is the hunger silently attacking life.

clearly distressing details from gaza. an unclear situation. we will be talking to our correspondent from jerusalem in eight while who has more details as to what went on the last 2a hours. around the world and across the uk, this is bbc news. let's look at some other stories making news. the father of a teenage boy who murdered brianna ghey has been jailed for 15 months after pleading guilty to sex offences. kyle ratcliffe, aged 36, admitted two offences of exposure and one count of taking an indecent photo of a child. his son eddie ratcliffe was convicted alongside scarlettjenkinson of murdering 16—year—old brianna in a park in culcheth, cheshire last year. administrators for the cosmetics and skincare chain of stores the body shop say 116 outlets will stay open in the uk. but they are closing 75 shops over the next six weeks and will cut about 500 jobs as part of a restructuring programme. the uk arm of the global beauty chain was put

into administration this month. a bbc investigation has found that millions of chickens sold in uk supermarkets show clear signs of skin burns caused by being left to live in their own waste. you're live with bbc news. russia's president vladimir putin has warned western governments not to send troops to ukraine, saying the consequences of doing so would be "tragic". in his annual state of the nation address in moscow he claimed his forces were advancing confidently inside ukraine two years after the invasion. our russian editor steve rosenberg has more. it was president putin's 19th state of the nation address. and he used it to send this warning to western nations. "don't send your troops to ukraine."

translation: they need to understand once and for all that we have _ weapons, too, that can strike targets on their territory. and everything they think up and scare the world with risks a nuclear conflict and the end of civilisation. regarding russia, he pledged to reduce poverty, boost the birth rate and raise incomes. well, there is an election coming up. the kremlin clearly wanted russians to see this speech. it was shown live on billboards. even in some cinemas. although this moscow movie house wasn't exactly overflowing. putin and popcorn, not an obvious combo. this address was part campaign speech, part state of the nation,

and state of the world as vladimir putin sees it, with warnings to the west and promises to his people that life here will get better if he stays in the kremlin. as for the current wave of repression in russia and the intensifying crackdown on dissent, there was no mention of that. and the audience, russian mps and senators, had little to say about the death in prison of the country's most famous opposition leader. are you not concerned about the state of the nation or its reputation after the death of alexei navalny? who's that? i am ready to comment on the message which vladimir putin delivered but not on other issues, so thank you. the president, too, has stayed silent on mr navalny�*s death. alexei navalny is expected to be buried tomorrow at this moscow cemetery. his allies have accused the russian authorities of blocking their plans for a public memorial

service for him. as for the kremlin, the choreography here sent a clear message — that on russia's political stage, there is only room for one man. steve rosenberg, bbc news, moscow. for more analysis of putin's speech, we can speak now to soviet and russian historian and author of several books on the kgb and russian foreign intelliegence, amy knight. thank you so much forjoining us here on the context. i was struck by steve's peace with him when he said this was the 19th state of the

patient addressed by vladimir putin, which is incredible. watching him over the two hours, who is he directing the state of the nation address at, who is his audience? the audience address at, who is his audience? tue: audience was address at, who is his audience? tta: audience was the address at, who is his audience? tt2 audience was the russian parliament, both houses of parliament and the

ministers and high level officials in pickens government. other people coming in. yes, it was also a message to the russian people in general. i don't know whether many of them would want to sit down to a

two hour speech. it was one of the longest speech is that mr putin has made. the way i heard it kind of a big pep rally. but only for putin to

re—election of which he is assured but also for the war in ukraine he was trying to ignite peoples support behind us. he made it clear that this work is not going to end. as he often does, he used nuclear, the word due several times talking about the sophisticated weapons that

russia has at the moment. and presumably that is directed at an outside audience. yes, of course. be because his speeches are so much propaganda i think it is hard for westerners to sit and listen and take all of it so seriously. the usual nuclear threat was there. i

think putin is hoping that the us does not... sort of make the west about how much support they do give. we talked about things about alexey navalny pointed out not mentioned once in that lengthy speech. putin has never mentioned alexi navalny

his name. neversaid his has never mentioned alexi navalny his name. never said his name out loud. i think it's very interesting that at the end of putin speech he said everybody was standing up to applaud 119 times during the two hours. but before the end of the speech he said "we in russia i won

big happy family, we're united. " i could not feel the irony of that given that tomorrow there's going to be a funeral service for alexi navalny. the russian authorities have already made it clear that they are going to do everything they can to prevent people from making it a

big issue. more arrests have been happening. simultaneous,
