as a terrorist organisation by the several western governments. these are some of the latest images we've received overnight. you can see massive explosions over northern gaza as seen from the israeli city of sderot. the united nations says there are now 1.5 million people displaced in gaza. more than 700,000 are reported to be sheltering in un facilities. it warns its sites in the south of the territory are now over capacity, and that's causing "severe health and protection risks" for that group of displaced people. we'll have more on the diplomatic efforts to end the conflict in a moment. but first, let's get a sense of the situation on the ground in gaza. we start with this report from jon donnison. and a warning — there are distressing images from the start. four weeks in to this war, the death and the suffering is endless. and in gaza, no place is safe. the un says this school injabalia in the north was hit this morning, killing at least 15 people. thousands had been seeking shelter there. "god will take my vengeance," this young boy says. "i was standing here when the three bombings happened." "i carried a body and another decapitated body "with my own hands. "where should i go?" he says. "they have hit the shelters. "since when has it become normal to strike shelters?" israel says it's looking in to what happened. gunfire and in the north of gaza, its ground offensive is pushing forward, tightening its grip on hamas, who israel says is using civilians as human shields. hamas is outgunned, but these pictures from its military wing claim to show it fighting back. more than 20 israeli soldiers have been killed since the ground offensive began, as the number of palestinian casualties continues to rise. the us secretary of state met with arab leaders in jordan this afternoon. antony blinken again asserted israel's right to defend itself, but... protecting civilians will help prevent hamas from further exploiting the situation. but most important, it is simply the right and moral thing to do. when i see... ..a palestinian boy or girl pulled from the wreckage of a building, it hits me in the gutjust as it hits everyone in the gut. and i see my own children in theirfaces. and america is also worried about this conflict spreading. israel's military has said it targeted a terrorist trying to cross over from lebanon on its northern border last night. less than a mile away in the town of shlomi, volunteers have been preparing food for israeli soldiers amid fears the powerful lebanese militia group hezbollah could escalate this crisis. very serious, very sad. we cry at night. everybody doesn't. .. i don't sleep at night. i watch tv all night. we watched all the terrible cases, everything that's happened. we run. when there's a siren, we run. and when we can, we work. and, yes, we are under danger. we're risking our lives. there has been so much fear and grief over the last four weeks. and it's farfrom over. jon donnison, bbc news, jerusalem. with more on this, we can speak to bbc arabic�*s mohamed taha. whojoins us from who joins us from the bbc newsroom. let'sjust who joins us from the bbc newsroom. let's just start with what looks like an explosion at a refugee camp in gaza. what do we know about this?— we know about this? what we understand — we know about this? what we understand from _ we know about this? what we understand from the - we know about this? what we understand from the health . understand from the health authorities in gaza, that this refugee camp in the middle of the gaza strip, was hit by a missile or a rocket and caused at least a0 deaths so far in that refugee camp. this is coming after a few days from hitting another refugee camp, which was a refugee camp that left around 200 people dead in that refugee camp. and in this situation where, asjohn dennison said in his report, no safe place in gaza as forces are targeting hamas targets everywhere, and even if this target be mixed with civilian, civilians in this locations, they would hit as well. we had guest overnight talking about hitting places around water tanks, around bakeries, around food storages and around hospitals and schools that made, again, asjon donnisson

but we have also seen over the last 2a hours the us secretary of state antony blinken carrying out talks with arab leaders. what come out of these talks, was any kind of agreement reached, specifically around humanitarian assistance getting into gaza? , ., ., into gaza? these talks so that agreement — into gaza? these talks so that agreement between _ into gaza? these talks so that

for a ceasefire and they want to reach some understanding to facilitate the humanitarian efforts, but egypt would call for an immediate ceasefire, and that appeared clearly in the press conference between the two foreign ministers of the two foreign ministers of the two countries after the meeting. lincoln would seek to meeting. lincoln would seek to meet the palestinian president —— antony blinken. we don't know if this meeting would happen or not, but having the meeting and having this gathering was a positive sign, but we didn't see much coming out of it in the direction of having even humanitarian pause. antony blinken, before the meeting, the israeli prime minister and, meeting, the israeli prime ministerand, benjamin minister and, benjamin netanyahu, who ministerand, benjamin netanyahu, who confirmed that it wouldn't be any pause, it wouldn't be any ceasefire because any ceasefire or pause will make hamas fighter. briefly, i want to ask this question about humanitarian situation there in gaza. just briefly, we are hearing from the un that they are concerned about not being able to reach certain parts of this street. tell us what we know so far? yes, the problem is that most of the main roads in gaza were hit by the israeli attacks on gaza, israeli targeting hamas militants in gaza, and now the un is very difficult for them to work. they said they lost more than 30 of their employees. the medical authorities said they lost more than 150 medical staff and that more than 57 ambulance were hit, and now giving, as you said in the beginning of the bulletin, that 1.5 million people became displaced in that tiny piece of land is making everything difficult, practically the whole population of gaza strip are living or are less than half of the strip, they are living in streets and tense in the hospitals and schools. thank ou ve hospitals and schools. thank you very much- _ hospitals and schools. thank you very much. thank- hospitals and

sunday where its expected he'll continue discussions with regional leaders about the conflict. secretary blinken met with arab foreign ministers in jordan on saturday. they're calling for a ceasefire. but the us has warned ceasefire could benefit hamas. the us is instead calling for humanitarian pauses infighting. on saturday, presidentjoe biden was asked about progress towards such a pause. here's his response. any progress? yes. let's take a closer look at what those two terms — ceasefire and humanitarian pauses — mean. here's our diplomatic correspondent paul adams. it might sound like semantics but a ceasefire is a proper defined cessation of hostilities usually for a significant period of time, whereas a humanitarian pauses being described as a brief break, probably limited in time and location to allow a particular objective to be met, and in this case, twofold, and to secure better access for aid into the southern gaza strip, which is not the focus of israel's military operation at the moment, but is still an area where the israeli military activity is, particularly air strikes, and perhaps to see if there is any room for negotiations about the fate of hostages. that is why the americans are pushing this concept. it hasn't yet as far as one can make out been one that the israelis have decided to go with. all the impression you get from the israeli side is that they want to keep up this relentless pressure on hamas. my colleague from washington, helena humphries, have spoken tojon alterman, former advisor on middle east for the us state of department about humanitarian pauses and the chances of seeing them in this war. do you think that we could potentially see humanitarian pauses for civilians in gaza any time soon? i think we'll see some sort of a pause. with all these israeli hostilities with hamas, there is often something short of a ceasefire, but some sort of delimiting of free passage for people, of an ability to get relief in, i think we will see something but it is much less than the arab governments were asking for today. i think it is likely to be much less than the us government was asking the israelis for. that's interesting — much less than you think the administration was asking the israelis for. is there any gap there between the two? do you think their positions are widening? what kind of conversations do you think are happening behind closed doors right now? i think there has been a widening gap in the last several weeks. the us really sees the last two decades as a time where it has gained a lot of experience fighting insurgencies. we fought insurgencies in afghanistan and iraq and against isis in western iraq and syria, and there is really a set of principles about how you do that, how you split the population away from the combatants. how you think about — how you fight shapes, what you are trying — what you're trying to do at the end shapes the way fight. i think the israelis don't think that counterinsurgency is applicable in this situation. they have been dealing with hostility from palestinians for more than a century and think they don't need lessons from anybody. it seems to me there are a lot of signs that the americans think, actually we do have something to say that will be helpful, that will get you out of this endless loop. and the israelis say, let us handle this. so far, it is being inaudible but i think those differences are growing. the argument from the israeli government is that a full ceasefire, which is of course a greater undertaking than a humanitarian pause, would essentially allow for hamas to regroup and that is something the us secretary of state anthony blinken repeated on his trip as well to the region. what you make that? there is also the issue of where does the freeing of more than 200 hostages fit into this. i think there is a reasonable case to be made that hamas asking for a ceasefire now rather than making concessions and releasing hostages, i think you can make an argument that this is something that we should negotiate and hamas does not want to negotiate it. but what we're seeing is, i think we're going to see an increasing number of palestinian casualties, we're going to see an increasing number of images of palestinian casualties and there is increasing pressure on israel for the government to release all these — work to release all these hostages at whatever cost. how that plays out in palestinian politics and israeli politics, we will have to see. now director of the middle east programme at the centre for strategic and international studies. on saturday, huge protests were held around the world against israel's continued offensive in gaza. tens of thousands took part in rallies in cities such as washington dc, berlin, paris, ankara and tehran calling for a ceasefire. in the uk, police said around 30,000 people gathered in central london. there were also demonstrations in other english cities and in scotland, wales and northern ireland. here's aruna iyengar. there have been demonstrations in israel with thousands of people calling for the hostages taken by hamas to be released. a large crowd gathered outside the israeli ministry of defence in tel aviv. the event was organised by the families of some 2a0 hostages being held by hamas in gaza. many held photos of the hostages who include children and the elderly. injerusalem, police held back hundreds of protesters outside the residence of the prime minister, benjamin netanyahu, calling for his resignation. there's widespread anger in israel over the government's lack of preparedness for the october 7 attacks and its handling of the hostage crisis. let's take a look at some other news today. a major operation is underway at hamburg airport in germany. it's understood an armed man drove his vehicle through a gate onto the tarmac — with a child inside the vehicle. german media reports that two gun shots were also fired into the air. police say they're dealing with what they describe as a hostage situation — with at least two people in the vehicle, including a child. officers are said to be in contact with the driver. local media say the man's wife had earlier alerted the police to a possible child abduction. hamburg airport has been shut and all flights suspended. the union representing thousands of
