live outside al nasser hospital in khan younis. a place that many people in the north have lied to. —— —— fled to. palestinian health officials say at least 200 and a0 people have been killed since the end of the truce. at least seven palestinians were killed in an israeli attack in the early hours of sunday near rafah. we're also keeping an eye on what's happening further north. this is the view from southern israel, looking at the gaza skyline. all this as israel has come under renewed pressure from top figures in the biden administration. the defence secretary, lloyd austin has said israel driving the civilian population into the arms of the enemy — and that would be a strategic defeat. our middle east correspondent hugo bachega has the latest. khan younis in southern gaza. palestinians have been seeking safety here. now, a target for israel's attacks. explosion hamas leaders are thought to be hiding in khan younis and people have been told to evacuate further south. the bombing of the city was the heaviest in the war so far residents say. translation: the israelis told us | that khan younis was a safe zone, | which led us to flee here. now, even khan younis has become a war zone. where are we supposed to go? our children are stranded on the streets. this was the scene when aid arrived in khan younis. 100 lorries with humanitarian supplies entered gaza from egypt yesterday. aid agencies say it's still not enough. chanting in israel, the agonising wait continues for the families of the hostages who remain in gaza. around 140 people are still captive. hamas says no—one will be freed until there's a permanent ceasefire. in tel aviv last night, thousands gathered to call for the release of the hostages. yelena trupanov, who's 50, was freed with her motherjust two days ago. her husband vitaly was killed by hamas. theirson, sasha, remains in captivity. translation: i'm happy and excited to stand here in front of you. - i came to say thank you because without you i wouldn't be here. and now we have to go back and get my sasha. the rally was interrupted by blaring sirens warning of the risk of incoming rockets. prime minister netanyahu spoke for the first time since the end of the ceasefire. he insisted military pressure was the only way to free the captives. translation: we will continue the war until we achieve - all its goals, and it's impossible to achieve those goals without the ground operation. from israel's main ally, the united states, a clear message — it cannot repeat in the south what it did in the north. i have repeatedly made clear to israel's leaders that protecting palestinian civilians in gaza is both a moral responsibility and a strategic imperative. talks between israel and hamas have collapsed. the families of the hostages hope for them to come home. in gaza, people hope the guns will once again fall silent. hugo bachega, bbc news. earlier, mark regev senior adviser to the prime minister of israel spoke to the bbc about what will happen to gaza once the israeli government eliminates hamas. it will be a better situation, because hamas has been controlling gaza for 16 years, not only has that been terrible and terrific for the people of israel, but that has been very sad for the people of gaza. what has hamas brought the gaza strip and the palestinians in gaza over the last 16 years? poverty? bloodshed? misery? surely the people of gaza deserve better than this extremist terror regime but doesn't give a hoot about the well—being of the people of gaza, and is happy to sacrifice the very last gazan as long as they can advance their crazy agenda. joining me now is our correspondent hugo bachega. that is an important part of the story, what happens if and when israel manages to remove hamas. what happens after that?— happens after that? there's been discussions _ happens after that? there's been discussions about _ happens after that? there's been discussions about the _ happens after that? there's been discussions about the palestinian | discussions about the palestinian authority which controls the west bank, the other palestinian territory, taking control of the situation in gaza. it is something that has been discussed, not only in israel but also by israel's partners, the americans, in particular. the main concern is about what is happening in gaza right now as this is really offensive continues. we've been talking about the humanitarian situation in gaza and how the situation in gaza and how the situation has been desperate for the population there, because they have been widespread shortages of basic supplies, humanitarian aid, the aid that has been delivered right now, the un aid agencies have said that it isn't simply not enough to meet gaza's needs. we see pictures of hospitals now completely overwhelmed by the high number of casualties wallowing these recent attacks, having to operate with very limited resources. there is a lot of discussion about what is going to happen after and if hamas is removed from power in gaza, but the situation right now is very concerning.— situation right now is very concerning. situation right now is very

few days ago, saying publicly that israel needed to act according to international humanitarian law. if they are saying these things in public like that, does it suggest that they think israel is not listening to what they are telling them behind the scenes?- listening to what they are telling them behind the scenes? i think it's very interesting _ them behind the scenes? i think it's very

interesting to see that there i very interesting to see that there has been a change in the states coming from senior american officials. the us defence secretary said yesterday that it was a moral responsibility to protect the civilian population of gaza, essentially suggesting that the ferocity of the attacks in gaza could drive people to support hamas. essentially saying you could be driving the population into your enemy's arms, i think those were hers words —— his words. it also antony blinken singh israel has the right to defend itself, but too many palestinians have already been killed in gaza. the message is clear here, israel needs to do more to protect the palestinian population, the civilian population of gaza as it goes ahead with this offensive. israel should not repeat in the south what it did in the north. northern gaza was the focus of the initial phase of the israeli offensive, you can see now that most offensive, you can see now that most of the attacks, many of the attacks, have been focused on southern areas of the gaza strip, especially khan younis, which is a major city in the south, hundreds of thousands of people have been sheltering in khan younis after fleeing northern gaza, and this is where members of the hamas leadership are believed to be hiding. it is a very desperate situation for the population there. thank you, hugo. let's talk a bit more about that international political element. i spoke earlier to jane kinninmont, policy and impact director, european leadership network. i started by asking her what she thought of the prospects of forging a new deal between israel and hamas. to replace the one that broke down. there will eventually be another attempt, but it's very unclear what a sustainable political way out of this might look like. so, what you've seen is that there was an agreement between israel and hamas because each was able to give the other something that they wanted. but ultimately, everybody knew that they were going to go back to fighting. and in the end, it seems hamas thought that since fighting was going to resume anyway, they might as well keep some of the women hostages so that they still had a bargaining card to play in the future. the kind of deeper problem here is that it's very unclear what will happen. what will happen, even if israel does manage to defeat hamas militarily, much of the rest much of the rest of the world thinks there needs to be a return of the palestinian authority or some wider palestinian leadership that can take the palestinians down a peaceful road to a state, but benjamin netanyahu is telling his own people that he will never let that happen. so there is this bigger looming question of what the future can look like and how there can be a peaceful solution. how much is benjamin netanyahu's decision—making being driven by the fragility of his own political position, because israel was a deeply split nation before the 7th of october, wasn't it? so how much is that impacting the decisions that he's making now? this is definitely a major factor because it is generally assumed that after the war he will be replaced. now, he is a long—time political survivor, things could change. but many of his own supporters really lost faith in him because of what happened on october 7th and the way that it's been seen as a major security failure by the israeli states, as well as obviously a dramatic and illegal operation and change in strategy from hamas. so this will be a factor as well. and the families of the hostages, of course, are leading a lot of protests inside israel. interesting on that point as well, the hostage family forum have also said that they are demanding an urgent meeting with israel's security cabinet, and still, haven't yet 18 hours after asking, had that meeting. we'll keep you up—to—date with that story from here in jerusalem through the day today on bbc news, but let's head back to london. over to you, azadeh. to france now — where one person has been killed and two others, including a british man, have been injured, in a knife and hammer attack in central paris. the french interior minister gerard darmanin has said the attacker targeted tourists around quai de grenelle — which is close to the eiffel tower. now, this was the sequence of events. the suspect fatally stabbed a german national. the man was then pursued by police and attacked two other people with a hammer, before being stopped with a taser and arrested. the suspect is a 26—year—old french national. officials say the man was known to authorities in france, for trying to stage another attack in 2016. french anti—terror prosecutors say they will be taking over the investigation. here's what the french interior minister told reporters — about the suspect. translation: he told police officers he was angry - at what happened in gaza. and he said that france is complicit in what israel is doing and he was fed up of seeing muslims dying. for more on this story here's our correspondent, hugh schofield. it seems quite clear that there is a link with what's happening in gaza, that it's spill—over. this man is a man, french national of iranian parents, born in neuilly—sur—seine, which is a very rich part of paris and lives with his parents now in the suburbs, so it doesn't look like he fits any kind of classic profile that we've heard recently of lone, lone wolf attackers. on the other hand, in the sense that he's not from a deprived cite or banlieue. on the other hand, quite clearly he does have a record. in 2016, he was found guilty of planning an attack in la defense, the business district west of paris, in western paris, and was sentenced to five years in prison, came out in 2020, at which point it was clear that he had psychiatric problems as well and was to follow a treatment, a course of treatment. and what gerald darmanin, the interior minister, was saying there, was that one of the key questions is going to be whether that treatment was being followed. i think it's a conclusion that everyone is taking as read, at least in a kind of preliminary way, that there was a link with what's happening in gaza in that events over there and the publicity surrounding it and news surrounding it, as would have triggered him into doing what he was obviously kind of predisposed to do anyway, having this psychiatric problem and a past record of radicalisation and was on a kind of watch list for the intelligence services. that was hugh schofield. a major incident has been declared by police in the north of england after heavy snowfall caused huge disruption and challenging conditions on the roads. people are being urged to stay away from cumbria and only travel if it is absolutely necessary. a yellow weather warning has been issued across the midlands, northern england and wales. scotland has alsdo been hit. with the latest, here's louisa pilbeam. the northwest of england has seen up to 15 centimetres of snow in the last 2a hours. in kendal, cars came to a standstill. on the motorway near tebay, drivers were stuck for hours. in grasmere, more people were stranded in their vehicles. and in ambleside, these scenes meant drivers were told to leave their cars and make their way to an emergency refuge. paul smith was one of those stuck there for hours. the snowjust came down, and as you can see now, the road all the way down is still blocked, we're still about 1.5 miles from ambleside, and it's just been like literally moving ten yards, stopping again. this was ant brett's view from his car on the a595 in cumbria on his way to a family wedding. he said he was stuck for 19 hours without food or water or any help from emergency services. siren wails cumbria police and the area's fire and rescue service urged people not to take to the roads. a spokesperson for cumbria constabulary said: communities have been opening local centres for people to stay. many of our community have got that cumbria spirit where they'll crack open hotels and bed and breakfasts and help people out there who are tourists or even just visiting just for the day or even on holiday. with the snow, ice and cold disrupting transport, there is also an amber cold health alert issued by the uk health security agency that remains in place forfive regions in england, including the northwest. louisa
