this is cnn breaking news. >> hello and welcome to our viewers joining us here in the united states and all around the world as we continue our breaking news coverage of the israel/hamas war. i'm rosemary church. qatar's foreign ministry says it will announce in the next few hours when the truce between israel and hamas will begin. a diplomatic source says it's likely to start friday, midnight local time at the earliest. the news comes after israel said on wednesday that the expected release of hostages and a pause in fighting with hamas were delayed. both u.s. and israeli officials pointed to logistical details for that delay. ahead of the expected truce, israeli forces continued ground and air operations, striking parts of northeastern and central gaza, though palestinians say areas further south were also hit. israeli prime minister benjamin netanyahu expressed confidence the deal would soon go into effect and made clear the war against hamas is far from over. >> translator: the war continues. the war continues. we will continue with it until all our goals are achieved. to bring back the hostages, to demolish hamas, and ensure that the day afterwards there is no source that educates terror to children and pay terrorists. >> cnn correspondents are following all the developments. claire sebastian is live in london, and eleni is standing by in cairo. i want to first go to london. and claire, hopes for the families were raised when israel's cabinet approved that hostage deal. but now, of course, the hostage release and temporary truce with hamas won't happen until friday. talk us to about what's behind the delay and what happens next. >> yeah, rosemary, it wasn't immediately clear what exactly caused this delay, but no one who is out speaking about this is suggesting it's a problem with the deal itself. they're pointing to implementation issues, logistics. one israeli media was reporting on wednesday that perhaps neither israel nor hamas had actually signed the agreement. but it's not clear how much of a difference that would make. the white house is saying that a one-day delay was designed to minimize the possibility of something going wrong, and as you said, we're hearing from the qatari foreign minister this morning that talks are ongoing on how to implement the deal they're progressing. positively they are saying they will announce in the coming hours the timing for that truce and a diplomatic source telling cnn that the earliest would be midnight local time. so that's 5:00 p.m. on the u.s. east coast. so that's where we stand right now. as for what happens if and when this does come into effect, this pause in fighting followed by hostage releases, we assume, and certainly this is what the israeli national security council is saying, that it will progress along the lines of what we'd previously heard about the deal. that this will involve some 50 israeli hostages, that they will be released in stages, a minimum of ten per day, according to the qatari side, and that in return hamas will be able to secure the release of some 150 palestinian prisoners from israeli jails, heavily focused on women and in particular male teenagers, we understand, minors, women and children. they will also get more aid trucks into gaza, and a six-hour window each day where neither the u.s. or israel will fly surveillance over gaza. that's sort of the contours of this deal. i think the question really is how far this can be pushed. you heard prime minister netanyahu saying that this is really just a pause, that the war will continue. israel's second goal aside from getting the hostages out is, of course, to completely dismantle hamas. and you have the assume that hamas wants to keep at least some hostages in gaza to provide cover for this ongoing israeli operation. meanwhile, we're hearing from the qatari side, from egypt, from jordan, they hope this will set some kind of diplomatic template that will lead to something more sustainable, a more sustained pause, perhaps even a ceasefire, that as we know, israel is still ruling us out. >> joining us live from loon with that report. let's bring in eleni now. she is in cairo. so what more are you learning about when humanitarian aid will likely resume and what's to be included in that assistance as agreed to under the deal? >> well, right now what we know from the sources on the ground at rafah border is that there is more activity than they've seen in the past few weeks. lots of trucks lined up, aid trucks ready and in anticipation of this four-day truce to try and get in as much aid as possible. look, the u.n. agencies, international organizations, have all reiterated this point, that there is a dire need for medical supplies, for food, for water, as well as fuel. 1.7 million people currently displaced. and we've heard from these aid agencies just what people are going through. running fast out of food and water. and these stories are coming in very fast from the organizations. the norwegian refugee council says that they need more than just this four-day pause. they're calling for a right out ceasefire. and they say that neither hostages nor access to humanitarian relief should be a bargaining chip for military negotiations. they've also reiterated the point, and we've been covering these stories, rosemary, that hospitals have run out of medical supplies, have run out of anesthesia. doctors having to take very tough decisions to embark on surgeries without any anesthesia. and also amputations without anesthesia. imagine what that's like not only for the patient but the doctors themselves. and these stories have really been amplified over the past few weeks. we also heard from the u.n.'s martin griffiths yesterday, and he was talking about the negotiation, what it takes to get aid into gaza. while he says they negotiate with the egyptians, all decisions come out of negotiations with israel so. we know that israel is at the center of this in terms of allowing more aid into the gaza strip. so we're waiting to see what will happen at the rafah border. we know there are a loot of trucks, but i just want to give you a snapshot in terms of the people i have met here in cairo. the hotel that i'm staying in is hosting dual national passport holders as well as foreigners that have just been evacuate out of gaza. and we met one family that was talking about not having bread, not having food, not having anything available to them for such a long time that everything was scarce. they were eventually trapped at the rafah border waiting for their names to get on the list so they could evacuate. this was a family of five. i mean, with three little children, and one can only imagine what they've been through because they've just been displaced from one area to the next. international agencies have been very clear about the untenable scenarios playing out because of the food and water situation. and then fuel is another issue because that keeps generators running for the hospitals. the u.n. has also categorically said 68% of people that have died in gaza right now are women and children, and the fact that children are stuck in the middle of this, frankly, rosemary, on both sides has become a symbol of the suffering we're seeing playing out over the past few weeks. this truce is going to be absolutely pivotal. the hope is it can be extended to get more aid in, to get more humanitarian relief over the coming days. >> eleni, many thanks for that live report from cairo, appreciate it. and so the agonizing wait will continue for hundreds of families for their loved ones to come home. cnn's chief international correspondent clarissa ward reports from tel-aviv. >> reporter: even as the first batch of hostages is poised to be released, they are not backing down. look in their eyes, this protester says, tell them that every day you are doing everything that it takes. for 47 days, friends, family members, and supporters of the estimated 240 hostages in gaza have demanded the israeli government prioritize bringing them home. here they gather in support of calderon, whose children, 12-year-old aras and 16-year-old sahar, were taken along with her ex-husband. tell me what you're going through now. are you hopeful? are you anxious? are you in denial? >> i smile, i laugh, and then i cry. >> reporter: do you know anything? have you heard anything? >> nobody knows anything. nobody. nobody. no information. i have to pray. we have to pray. >> reporter: calderon is not the only parent desperately waiting and hoping for news that has yet to come. 9-year-old emily's father thomas was initially told his daughter was killed on october 7th only to then get the news that she may be alive and held in gaza. i want to jump through the roof with hope he told us today about the possible prospect of emily's release, but i also have to keep a level head emotionally. it's a challenge kalderon is all too familiar with. >> every day is tough. every day all day is tough. i don't want to think, i don't want to feel, because it's too painful. you know, when they start to ask me like interview like you, show me the picture of your child, tell me what last thing he told you, it breaks my heart because the last thing he told me was, mom, be quiet. i love you. he was worried for me. >> reporter: when you think of, god willing, your babies come home and are part of this release, do you worry about how they will be changed by what they've experienced? >> they are changed. they won't be the same. they got -- they've been kidnapped, brought away from their parents, the house, the safe place. they kidnapped the innocence. >> reporter: at the central hostage square in tel-aviv, prayers for those who will come home over the next few days, and a promise to keep pushing for those who will not. clarissa ward, cnn tel-aviv. >> qatar's lead negotiator says the work as hostage mediators was extremely intensive. in an explosive interview with cnn's becky anderson, the qatari minister of state hailed the agreement as significant and offered more details about the hard fought deal to free hostages and get humanitarian aid into gaza. >> within the four days pause, in each day there will be an obligation on each side. an obligation on the israelis and an obligation on hamas. making sure they're going to fill those obligations each day. each day we aim to have a number of releases, because the number is big. so we've managed to get the parties to agree on the releases systematically. in other words, there will be an organized schedule allowing the releases in each day, and each party is quite familiar now with their obligations. >> ten hostages released on day one, for example -- >> a minimum, a minimum of ten. >> who will be released? >> so this agreement specifically focuses on civilian women and children. on each side. on both sides. and we hope that within the four days we will be able to complete the release of women and children on both sides, moving to the safe side, away from this war. by the first hours of the agreements, we will be notified of the official list of people on each day. and by having that list, we will make sure we notify either the sides, the parties themselves, or even the countries that have their hostages in the gaza strip currently. >> hamas has said it doesn't have all the hostages, and it needs time to get around to gather information about hostages that it doesn't hold and find out where they are. many have called that just a talking point, a cynical ploy to buy time. >> the obligation on hamas on the first day is very clear. they need to provide us with that list. they've been granted that period of calm and not only the period of calm but also preventing any military clashes, ground invasion, air surveillance, that will provide them with the room to provide us with that commitment. >> you've described in the language of this deal -- you've described it as a truce in the gaza strip. and i think that language is really interesting. the use of the term truce, this is by naming a ceasefire. and the fact that this is in the gaza strip, the main pillar of which, of course, is clearly the hostage release. what happens as far as humanitarian aid is concerned? what is the commitment on both sides as far as that uptick in aid is concerned? >> sure. so this agreement has two major components. the first one related to the release of the hostages and the second one's related to providing not only a quantity but also quality, humanitarian aid and assistance as needed. one of the most interesting components within that humanitarian aid, becky, is the fuel. and the fuel has been a debatable issue in the early times of that conflict. now we've managed to secure fuel being provided for a vital infrastructure such as hospitals and others. >> the israelis have been very specific. they have said this is a truce period. before it starts, hostilities will continue. and very specifically, once this pause is over, the war will restart. is that useful in negotiations, that sort of language? >> our work is not done. we're still going to continue to talk more to the parties to de-escalate, to seek a longer period of ceasefire. >> the israelis are not talking about a ceasefire at this point. they have categorically ruled out a ceasefire until all hostages are released. and at present, you are not mediating any talks on the soldiers or men being held by hamas. >> well, listen becky, even the temporary ceasefire was not considered in the early times by the israelis. so we still -- we remain hopeful. and our effort is not going to stop at this level. our work is not done. we're going to continue working with both sides, hoping that we can secure this bigger objective. >> if there are families of hostages watching this interview today, families of hostages who are young men of serving age, what is your message about the likelihood that those israeli soldiers will be released any time soon? >> so we're doing everything that we can. as soon as the both parties wants to keep seeking qatar's assistance in mediating, we can respond positively to that request. so we know that our mission did not finish and our work is continuous for the better cause, and as you said, our hope is really that we see a period where we can put an end to this war and let the people leave and reduce this humanitarian suffering for the people in gaza. >> still ahead this hour, potential freedom for hundreds of palestinians jailed in israel. until they're released, a radio station provides a lifeline. back with that and more in just a moment. the deal for hamas to start releasing israeli hostages was originally supposed to start this hour, but israel now says it's on hold until friday, including a four-day pause in the fighting. at least 150 palestinians held in israeli jails are also supposed to be freed, but prime minister benjamin netanyahu says not everyone will be eligible. >> translator: the agreement achieved does not include a release of murderers, and it does include the agreement of the red cross representative to visit the hostages and transfer of medication. >> according to a cnn count, the vast majority of palestinians eligible for release are male teenagers aged 16 to 18. the charges against them include throwing stones, harming regional security, support for illegal terror organizations, illegal weapons charges, and incitement. two are accused of attempted murder. palestinians held by israel have been in jail for years. while they wait for their possible freedom, their families are sending them messages through a radio station. >> reporter: a lifeline keeping some connection between families torn apart. callers send in voice notes. the radio presenter. they've dedicated its airways for years to the families of thousands of palestinians desperately trying to reach out to their loved ones held in israeli prisons. the young listener's aunt a palestinian activist, was arrested by israeli authorities along with thousands of other palestinians after hamas' deadly october 7th attack. the station is trying to support the families so desperately waiting for any news from inside israel's prisons. >> translator: we have three phone lines here to receive messages from families of the prisoners. because of the volume of the calls, people weren't getting through. so we've started making announcements. if you can't get through, send us a voicemail through whatsapp. >> reporter: in the horrifying aftermath of the attack, israel not only carried out mass detentions of palestinians but is denying prisoners all family contact. this is the only way their families can reach out. the sheer volume of messages, evidence of the realities of imprisonment here. israeli law allows palestinian prisoners to be detained indefinitely without trial or stated charge. the families don't even know whether the prisoners get to hear their messages, but that doesn't stop them from sending them. the israel/hamas hostage swap, exchanging 150 israeli-held palestinian prisoners, women and teenagers, for 50 hamas-held hostages means that for now there is hope for both israeli and palestinian families. we are going to meet a palestinian lady who one of her loved ones is coming home. but as ever in this context and this situation, it's never that simple. families on both sides, even those who are awaiting the return of those who love, are also dealing with the reality of those who won't be coming home. her sister-in-law was arrested alongside her three sons. the sons remain in prison. she is on the list to come home. she said neither she nor her sister-in-law is involved in the politics of this war, yet they suffer its consequences. >> her sons, they get married, so they have kids. they are waiting to see their grandmother, you know. she has a beautiful relationship. she loves everybody. >> reporter: in the midst of her joy, she is beginning to hope that her husband, the longest serving palestinian political prisoner, could also be released in a swap. >> it is a happy day for us. this is a start, that means my husband will come. my husband who's in prison now since 44 years when he was arrested it was in the first time in 1978. >> reporter: the family is revered by many palestinians deemed a threat by the state of israel. valuable enough to hamas that they were included in the 2011 israel/hamas deal among 101,000 palestinians for one soldier. after hamas held him for five years. who else was swapped on that day? the man israel says is the ark tect of the october 7th hamas attack. a fact that haunts every move israel makes as it negotiates for the release of more hamas-held hostages. as families on both sides wait and hope. the occupied west bank. >> and we'll be right back. goli, taste your goals. welcome back, everyone. an update on our breaking news. qatar's foreign ministry says it will announce in the next few hours when the truce between israel and hamas will begin. a diplomatic source says it's likely to start friday as early as midnight local time or 5:00 p.m. eastern. the hostage release and israel's pause in its military campaign in gaza were delayed on wednesday. the white house says it's due to logistical details. hamas is expected to release at least 50 women and children over the next few days. and israel has agreed to free more than 150 palestinians held in israeli jails. while hamas says the truce deal will also allow hundreds of trucks to bring aid into gaza, many palestinians are still wary of what's to come. some say the truce will do little to make up for the damage that's already been done. and after weeks of unfath omable grief and loss, they want to rebuild their lives. the grim reality of everyday life in gaza, a warning, the report contains disturbing images. >> reporter: the gaza strip pounded for yet another night. in the neighborhood in central gaza, wounded are rushed to a nea
