much of the territory now a mass of broken buildings and rubble. more than 1,000 people have died, many more are injured, after several days of israeli bombing. we'll get the latest on the ground from rushdi abu alouf in gaza city, and anna foster, on the northern border with lebanon, where tensions are rising with the militant group, hezbollah. here, we'll be speaking to people in the uk desperately worried about family affected by the violence in both israel and gaza. also on the programme... labour leader sir keir starmer tells the bbc he's a yimby not a nimby — saying yes to house building in his own back yard. in the us, republicans choose a new speaker of the house of representatives — after his predecessor was ousted by a revolt from within his own party. and the handful of dust grabbed from an asteroid — and the clues it contains about the creation of the solar system. and the newsnight at 10:30, we will go deeper behind the headlines and speak live to key players on today's big stories. plus, a first look at tomorrow's front pages. good evening. we're live injerusalem, where a new emergency unity government and war cabinet is in place, as israel continues its mass mobilisation of troops, hundreds of thousands, on the southern border with gaza. the widespread expectation, that a ground offensive, across the frontier may be coming. but the un is calling for essential supplies to be allowed into the territory, where the humanitarian situation is deteriorating rapidly, as israel enforces a complete siege. it follows the unprecedented attack five days ago on this country, by militants from hamas — a group committed to the destruction of israel and designated a terror organisation by many western governments, including the uk. at least 1,200 people in israel are now thought to have died in the multiple assaults last saturday, including 17 british nationals. at least 1,000 palestineans have been killed in retaliatory israeli air strikes. we'll have the latest from across the region, with our international editor, jeremy bowen in the southern town of beeri, we'll be inside besieged gaza, with rushdi abu alouf. and anna foster has travelled to israel's northern border with lebanon, where troops have exchanged fire with hezbollah militants. but tonight, we begin withjeremy, reporting on the mass israeli troop build—up. yes, thank you, clive. this afternoon, we were invited by the israeli army to join a media trip down to see the front line, the edge of the front line in gaza. it was a trip there down through empty highways, past the town of sderot. we could see the israeli anti—missile system. we had to take shelter behind some bushes in a gutter with some israeli troops because of an alarm, an air raid, but then when we got there, we did see that while i don't believe they are ready yet, the israelis have made a lot of progress in getting their troops prepared for that moment, if and when and probably when, the order comes to invade gaza. in the fields and farms on the border where, in the fields and farms on the borderwhere, israel's in the fields and farms on the border where, israel's combat soldiers are creating jumping off points to invade gaza. late this afternoon, at kibbutz beeri, regular units and some 300,000 mobilised reservists were preparing for the order to move in that most israelis believe will come. the build up that we are seeing here is certainly the clearest evidence that i have witnessed that israel is preparing for a ground operation in gaza and if you add this to the formation of a war cabinet, you can see the direction they must be going in. israel's allies are gathering. antony blinken, the us secretary of state, is flying an overnight from washington. american support includes weapons and moving an aircraft carrier battle group close to deter allies of lebanon from joining the war. the to deter allies of lebanon from joining the war.— to deter allies of lebanon from joining the war. the united states has the back _ joining the war. the united states has the back of _ joining the war. the united states has the back of the _ joining the war. the united states has the back of the israeli -

"you're old. "you don't know what you're doing. "you haven't fought for a while. "you're not going." i said, "but if i don't go, then who does? "if i'm not in the front line, then who is?" the invisible ties that bind hold fast. israel is hurting, as another reservist says goodbye to his family — called up to defend the land that so many call home. israel is believed to have identified most of the hostages taken by hamas gunmen into gaza. israel's ambassador to the united nations says those captured number between 100 and 150. it's an anxious wait for families who haven't heard from relatives since saturday, as caroline hawley reports. twins osher and michael organised the music festival that became a massacre. osher is dead, michael missing. their sister ausa still can't fathom what's happened. family by family, the horrifying scale of saturday's atrocities is being revealed. at this stunned gathering of relatives and friends, osher�*s widow, who went to try and find him. translation: we thought he was alive, we had hope| but finally i found our car and it was covered in blood. all the front windows shattered by bullet holes, everything covered in blood — everything. the bodies of 260 people were found at the festival site. some survived by playing dead, others, we still don't know exactly how many, were abducted. karim giorno loves dancing and went to the festival with a broken leg. she couldn't run from the gunmen and her family haven't heard from her since saturday. the last time we talked to her it was saturday morning, 8.42, something like that. she sent us a message to the family group in whatsapp and she told us, "i love you and, if something will happen to me, know that i love you." several agonising days on, esther is also waiting for news of her son ohad and 12—year—old grandson ethan, kidnapped from their kibbutz. translation: | don't know if he's i had any food because he's being held captive by some madmen. i don't know if they've fed him. i don't know if they've given him enough clothes. it was cold yesterday. i don't know if they gave him a jacket. i am worried about my son but he is big and can handle it. a small child cannot do that. her daughter—in—law and granddaughters somehow escaped, when five gunmen stormed into their home. inside my heart, i'm very hurt. worried. i want to hope — i want to be in hope. esther yahalomy ending that report by our correspondent caroline hawley there. let's get the latest from around israel now. in a moment, we'll be speaking to our international editorjeremy bowen, who's in ashkelon, but first, to anna foster, who's near the lebanese border in the north of the country. we understand there has been cross—border fire with hezbollah? that's right. over the last several days now there is real anxiety and concern on the border over another group that, like hamas, has been designated a terrorist organisation by the us, the uk and others. that is hezbollah. an anti—tank missile was fired across the border this morning and israeli fighterjets morning and israeli fighter jets responded morning and israeli fighterjets responded by targeting hamas infrastructure in lebanon. we spent time sheltering the sirens went off along this border. there was the suggestion of new aerial infiltration from hezbollah into israel, perhaps drones, perhaps gliders, but that was met with a real sense of nervousness and fear. if a new french opens up in this war here in the north of israel it risks really feeding some of those deep fissures that exist in the region. hezbollah is backed by iran and something that took place in the middle east would reverberate around the world. . ~ middle east would reverberate around the world. ., ~ , ., middle east would reverberate around the world. . ~' ,, �* ., middle east would reverberate around the world. ., ~ ~ ., tojeremy in ashkelon in the south, we heard about the troop build—up from your report earlier, the big question, of course, if israel does go into gaza, the fighting will be intense, bloody, it will be very, very difficult and there are 150 also hostages being held. what do you think the chances are of a ground invasion any time soon? i think the chances are growing. based on what i saw today i would say they are not ready. they are still taking bodies of israelis as well as hamas gunmen out of those communities, the converters which the soldiers are turning into armed camps —— the kibbutzes. i saw supply trucks loaded with food and fuel pointing into gaza so i think the chips are falling into place. the unity government, the allies coming in, the uk foreign secretary today on the uk foreign secretary today on the us secretary of state tomorrow. they will be looking for diplomatic cover from their friends, they have already killed a lot of palestinian civilians in the course of the air strikes and many more will die if there is a ground invasion so israel will be looking for support from friends who will say israel is devoting itself and, given the constraints, respecting international law. i think as time goes on that will be controversial, to put it mildly. goes on that will be controversial, to put it mildly-— goes on that will be controversial, to put it mildly. jeremy bowen, our international— to put it mildly. jeremy bowen, our international editor, _ to put it mildly. jeremy bowen, our international editor, live _ to put it mildly. jeremy bowen, our international editor, live in - international editor, live in ashkelon, thank you. and with that, it's back to reeta, in the studio in london. thank you, and we'll be hearing more from clive towards the end of the programme. british airways and virgin atlantic have suspended flights to and from israel. a ba plane that was about to land in tel aviv was turned back as air raid sirens went off. 17 british nationals are now feared dead or missing after the hamas attack on israel. today buckingham palace said the king was appalled and condemned the barbaric acts of terrorism in israel. our special correspondent, lucy manning, has more. there is none to comfort her... they stand in manchester, but their thoughts and tears are for israel. there are few here and at vigils in leeds and glasgow tonight who do not have family or friends there. almost everyone knows someone killed, injured, attacked, missing, grieving, called up to fight or living in fear. i knew gili from my gap year in israel. i'm here to honour gili and all otherjewish people that have been brutally massacred with, you know, acts of monstrosity and terrorism. we are one, like, i may not know the people personally that have lost their lives, but i'm mourning them as if they were my own family. they includejake marlowe, a security guard at the music festival. tonight his family said they were heartbroken to confirm the crushing news that his death had been confirmed. also bernard cowan, a father of three from glasgow, danny darlington, a british photographer, nathanel young from london, who was serving in the israeli army, and today british mother miryam shafir buried her 30—year—old son, dor, who was also at the festival. news report: kfar aza was taken by surprise... in london, hilary freeman looked at the pictures of kibbutz kfar aza, filmed yesterday by the bbc. there was a massacre here. her cousin gitit hid for 30 hours from the gunmen. we learned on sunday afternoon that my cousin and her husband had survived, but her daughter—in—law, who was visiting with her seven and nine—year—old children, was shot dead by the terrorists. what impact has this had on you and your family? from the pogroms of russia and the holocaust, members of my family have been killed in every generation. i worked out this is the fifth generation since my great grandmother who have been affected or killed by anti—semitic violence, and itjust feels relentless. the wife of scotland's first minister, humza yousaf, is worried for her parents, maged and elizabeth from dundee, who were visiting a sick relative in gaza. they are now caught up in a war situation. my mum says there is continual bombardment from land, sea, air, they are terrified, she is terrified, she has not slept since monday. we've no electricity, we've no water. the food we do have, which is little, will not last. i have four grandchildren and miss home. the children here can't imagine the horrors the children there have faced. lucy manning, bbc news. sir keir starmer has added a new word to the political lexicon, saying he is a yimby — that is �*yes in my back yard' — in relation to his plans on housing. he says labour will build a million and a half new homes in england — if it wins the next election. he's been talking to our political editor chris mason packing up. this has been a labour conference full of expectation about this party's prospects, but against a backdrop of horror in the middle east. labour was condemned as being anti—jewish when keir starmer chose to serve in former leaderjeremy corbyn's senior team. the party's view now — exactly that of the government. what we've seen in recent days is appalling and shocking acts of cold blooded murder in relation to men, women and children, and responsibility for that terrorism lies with hamas, and israel does have, must have, the right to defend herself. now, obviously, that's within the framework of international law, but i think that hamas should immediately release these hostages. so including a ground war, for instance? israel going in to get those hostages — that would be acceptable, would it? israel has the right to defend herself, has the right to get those hostages back. a central theme of this conference has been labour setting out a bit more about what they'd do if they get into power. and one plan in particular has stood out. you're promising to build lots more homes. lots of governments make that promise, and, frankly, lots of governments fail to keep that promise, not least because they encounter a lot of local opposition. are you saying bluntly this is so important you will bulldoze through local opposition? yes, that's exactly what i'm saying. and so bulldoze through local democracy? look, we must build those houses, one and a half million houses. we will come up against people, as i referenced in my speech, who will say, "no..." including some of your own mps. "i want to build a better britain, but don't do it here" — that's what's held us back. now obviously we need to work with local communities, we need to ensure that planning goes up a level so it's not so localised. people talk about nimbys, not in my back yard. those who oppose development. are you a yimby — yes in my back yard? iam, yes. i think that it's very important that we build the homes that we need for the future. keir starmer has tried to junk plenty of labour's recent history, but the routine of singing the party's anthem to close this conference continues. sir keir�*s ongoing task — ending labour's routine of losing far more elections than they win. chris mason, bbc news in liverpool. republicans in the us house of representatives have nominated steve scalise to be the chamber�*s next speaker — after the last speaker, kevin mccarthy, was ousted in a right—wing revolt from within his own party. let's speak now to our north america correspondent gary o'donoghue — does this mean this is all over? far, farfrom it, i'm afraid. they have a nominee but he only got a handful more votes thanjim jordan from the right of the party and a number of those people who supported jim george and are threatening to not support steve scalise when it comes to a vote on the floor. it only requires a handful of republicans to hold out for us to end up in a round and round a drum situation as we had back injanuary when it took 15 votes for republicans to choose kevin mccarthy. in the meantime security assistance for israel on hold, security assistance for ukraine on hold. a week after the republicans rejected their own speaker for the first time in this country personal history, they are no closer to coming to a compromise and in the meantime the business of the american people are simply not being done. . ~ american people are simply not being done. ., ~ i. , american people are simply not being done. ., ., nasa scientists carrying out tests on dust from an asteroid say they've identified matter which could shed light on how the key building blocks of life were delivered to earth billions of years ago. the dust was brought back to earth by a nasa spacecraft last month. here's our science editor, rebecca morelle. the moment of truth for nasa, a chance to finally see what they hope will be a treasure trove — the fragments of an asteroid called bennu, and it is exceeding all expectations. this stuff is an astrobiologist�*s dream. just can't wait to get at it, it will be around for generations and generations. we will learn so much about the origin of the solar system, the evolution, and potentially how even life started here on earth. this is a single grain of asteroid. if we look closer in, the picture on the top left shows water locked up inside hydrated clay minerals. and there's carbon too — the white specks in this blue image.
