good day to you. i'm richard quest. 9:00 in the morning in london. 11:00 a.m. in gaza. and we are following two major developments that have happened overnight. the israeli military says a safe route from gaza city southwards has opened for civilians an hour ago, as israel forces fight their way into the city, the idf says the offer of safe passage to civilians is only good for four hours. that will be until 2:00 in the afternoon local time. one of the refugee camps south of the line, where palestinians have been told to go, was hit by a deadly explosion a few hours ago. a palestinian hospital official says more than 30 people were kid and more than a hundred wounded. the israeli military has not commented on whether it targeted the area. cnn's ivan watson joins us from hong iconic with more. let's start, first of all, i think with the blast. then we'll move to the safe corridors. what more do we know? >> we're seeing some first images, in daylight today, sunday, the recovery effort, and what you can see is a giant crater there in daylight, with many people hard at work, right to sift through the rubble there. now, eyewitnesss have described an attack that took place or some kind of detonation, massive explosion that took place on saturday night, in the al ma gazi refugee camp. according to the united nations, this is a community of about 33,000 people, before last month's conflict began, in an area of about 0.6 square kilometers. take a listen to what one of the survivors of this massive palast had to say. >> i saw a red light and then we were shaking on the sofa. then i saw all my sisters screaming. then i saw my father. when i saw myself alive, i looked to see who was still alive. i turned on the torch and my siblings were alive, but i did not find my father. i finally found him next to me. i moved him, i moved his hands, i moved his face. he did not respond. >> this woman went on to say that her father was killed in the attack. we had another survivor in the same hospital who said his two children were killed. the head of the nursing department tells cnn that he saw the poised of at least 33 people from this explosion, which he characterized as an air strike. the israeli military has not yet commented on whether or not it had anything to do with this strike. the death toll in gaza continues to grow at a staggering rate, richard. according to the palestinian health ministry based out of ramallah in the west bank, that's not the hamas health ministry, the death toll as of saturday afternoon, before this strike, stood at more than 9,400 people killed, more than 24,000 people in gaza wounded, and more than 70% of the fatalities coming from vulnerable communities that includes the elderly, children, and women. >> now, this safe haven, if you will, this corridor -- it's not the first time we've seen this, it opened up yesterday, the other day, when there were allegations that hamas had targeted people on it. but now, what do we know about this safe route? >> the israeli military announced that civilians should travel from the north of gaza to the south today, between 10:00 a.m., which is about an hour ago, local time, until 2:00 p.m. and that they should take sala aldine street and get south of this wetland that bisects the gaza strip. there are some challenges here, major challenges. first of all, as of last week, we had a hospital director telling cnn that ambulances were targeted by artillery on that very same road. another challenge, the announcement was made by the israeli military on twitter or "x." many people in gaza have no electricity or no access to the internet right now, due to the destruction there. how do they get that message? and then there's the other matter, which is, the strike that took place in this refugee camp is south of wadigaza, as well as other communities that the israeli military have claimed responsibility for striking with huge numbers of civilian casualties there. so the end result is, if you're a civilian in gaza, which is, of course, closed off by fences on all sides, it doesn't seem that there is any safe place for a civilian to take shelter in. especially when we have numerous accounts of hospitals and schools and places of worship being hit during this bombing campaign. >> briefly, ivan, do we know how many civilians it's believed that are still in there, that this evacuation order would likely apply to? >> i believe we've heard accounts of 3,000 to 4,000 civilians still in the north of gaza. that's what the ground forces from israel have gone in with their incursion, their ground operation, as of a week ago, and they claim that they are trying to encircle gaza city right now. >> thank you, sir! ivan watson, we'll talk more in the next hour. cnn is part of the first group of foreign press that have been granted access to israeli forces inside gaza. now, journalists that are embedded with the idf in gaza, they operate under the observation of israeli commanders in the field. they are not permitted to move unaccompanied. as a condition to enter gaza under idf escort, they have to submit all materials and footage to the israeli military for review prior to publication. cnn has agreed to these terms in order to provide a limited window into israel's operation in gaza. cnn's jeremy diamond was one of those embedded. >> reporter: at this israeli military post on the outskirts of gaza city, the fighting is fierce. >> the center of the gaza strip, the idf soldiers are fighting against the militants that are using all the houses that they can in order to harm and to get to the idf soldiers. >> one week into its ground offensive, israeli's military says it has encircled gaza city from posts like this. >> we're right now at an israeli military post inside the gaza strip, about 1 kilometer inside of gaza. gaza city is just this way. and as you can hear behind me, there is a lot of ongoing fighting between israeli forces and hamas militants. what they are trying to do right now is to flank the hamas positions. that's what the battalion commander just told me. and all of this intended to try to cut off gaza city from the southern part of the strip, as israeli forces also move in from the north. >> cnn was part of a small group of reporters given access to israeli forces inside gaza for the first time since the outbreak of the war. entering gaza using the same roads hamas militants used to carry out their brutal attack on october 7th. >> and today we're going on the exact same roads, to the same neighborhoods, to their area, to their trucks in order to go there, and be able to get them to pay the price, and to eliminate the hamas organization that held this attack on the state of israel. >> israeli military is taking us into gaza. we are inside an armored personnel carrier right now into gaza, here at the southern point of gaza city. >> reporter: but still, israeli forces face the danger of ambush from underground tunnels. >> and over there -- over there and inside the neighborhood, also. >> so in just this area, there are at least three tunnels. >> i believe at least, yeah. >> reporter: israel says many of those tunnels lie below residential buildings, and for weeks, it is relentlessly bombed those targets, killing and injuring thousands of civilians in the process. the forces here say that they are now working to secure a humanitarian corridor to help civilians flee the heaviest fighting. >> this is a huge objective for their bri indgade right here. the population would be able to go to the north from the south surely, in order to get the idf, in order to do it. >> reporter: for these soldiers, achieving that goal may see them deploy deep goo gaza city, where the prospect of deadly urban combat awaits. >> the idf will be here as long as it takes, weeks, months, years, until you make sure that israel is safe and secured, for the longtime period. if we need to get inside gaza house by house, this is exactly what's going to happen. >> jeremy diamond, cnn, with israeli forces in gaza. >> the idf has repeatedly called on civilians to evacuate northern gaza and move south. many people are on the move. they are seeking shelter anywhere they can find it. we've obtained exclusive footage of one such makeshift shelter, the al quds hospital in northern gaza, where thousands of displaced people are now camped out. cnn's salma abdelaziz reports on their plight, and i must warn you that the images in this report are graphic. >> reporter: where do you go when the bombs won't stop? where do you shelter your family when the shelters are full? for many gazans, the answer is a hospital. the head doctor shows us around. all that separates these families in the icu is this door, he explains. these are not proper sterile conditions. some 12,000 displaced people are camped out in al quds hospital in northern gaza, and every single person you see here has been told by israel's army to leave and move south. an evacuation order the u.n. previously called inhumane. this is not a place for children to play. this is a disaster, the doctor says! look, these are sick people, how can a man on a walker be evacuated? hospitals are protected under international law, but israeli claims hamas uses medical facilities as command centers. aid group and palestinian officials deny these allegations. either way, this is still not a safe place. step outside the doors and this is what you face. nonstop israeli artillery and air strikes. everyone here fears the explosions will only get closer, but there's nowhere else to run. across the street, desperate people steal basic supplies. the war and a suffocating siege is causing civil order to break down, the u.n. says. families cannot be expected to flee into this chaos, this father says. this is a war against our children, see how scared he is from the bombs? now we are alive, but tomorrow we could be dead! please save us, he pleads. less than a quarter mile away from the hospital, this is the aftermath of one of those strikes. residents pull people out of the rubble of their homes. they can depend only on each other, coms are down. no one can call an ambulance. just try and carry him out on your shoulder, someone shouts! are my mom and dad alive? the wounded man asks. the sound of war never ceases, you could die trying to help the living. this is one neighborhood during one hour in gaza, a tiny glimpse into the horror. the humanity and dignity of more than 2 million people that live here, the casualty of a war so many did not choose. salma abdelaziz, london. >> in a moment, we'll show you the rallies around the world, pro-palestinian, that are joining thousands of people. we'll let you u hear the proteprototester s s on the groround comingng up. this is s cnn. hours ago, demonstrations and protests one of many cities worldwide where thousands of people have showing their support for the palestinians. one participant said indonesia has an extraordinary history with the region, so there's strong support for palestinians living free from israeli occupation. in the united kingdom, the prime minister is coming under pressure among massive rally in central london on saturday. tens of thousands of people gathered to end a violence to the war between israel and hamas. it's the third weekend of demonst demonstrations. >> it's a bloodshed and these israelis are targeting hospitals, schools, and you can't -- we can't stand by and just watch this. >> we can only hope. we just have to keep going until they do. there's power in people. there's so many people here, and we just have to keep going until they do listen. >> the police are reporting 29 arrests for inciting racial hatred under the racially motivated, crimes, violence, and assaulting a police officer. it wasn't only in addition to the thousands you see gathered in berlin, demonstrations took place in capital cities, such as paris and santiago and chile and in caracas in venezuela. in washington, there were protester who is marched to the white house, carrying palestinian flags and signs that red, stop the massacre, let gaza lid. cnn's gabe cohen spoke to some of those who were there, calling for the president, joe biden to push for a cease-fire. >> reporter: well, thousands of protesters marched through washington and ended up here at the white house after that huge rally just a few blocks away at freedom plaza. hours of speakers who called for an end to the bombings and the ground operations in gaza. but also, demanding that the white house and president joe biden call for a cease-fire and end its unequivocal support for israel, saying that it could be a seriou024, if he does not call for that cease-fire. here's what some of those protesters told me. >> my message to president biden is, i voted for you and i regret it. >> reporter: will you vote for him in 2024? >> absolutely not. >> how i'm going to vote for him? i'm not going to vote for him. because he supporting israel. he's asking for $14 billion to do more killing of the palestinian people. >> reporter: and organizers told me that they had hoped that this would be the largest free palestine rally in u.s. history, and while i can't confirm that, i can tell you that it is by far the largest we have seen here in washington since the war began last month. gabe cohen, cnn, washington. it may be a year away, but the u.s. presidential elections is on the minds of many arab american voters, as you heard in gabe's report, especially as the tensions increase. the voting pollack was once fairly reliable for democrats and president biden, and now they're looking for alternatives after the events of october the 7th. cnn's diane gallagher explains why. >> you can't ignore history. >> reporter: it's not a statement imam hamut ever thought she'd make. >> i voted for biden. >> reporter: and are you going to vote for him again in 2024? >> i mean, if you would have asked me a month ago, i would have said, absolutely, 100%, no doubt about it. but honestly, the past few weeks have changed everything and i don't know anymore. >> reporter: the michigan immigration attorney is one of a growing number of muslim and arab americans who say they are reconsidering their support for president joe biden, due to his response to the humanitarian crisis and rising death toll in gaza. >> reporter: the democratic party risks losing a generation of young voters and multiple generations of arab american and muslim voters. >> reporter: perhaps nowhere is the sentiment more pronounced than here in dearborn, which has been called the arab capital of north america. we sat down with democrats who helped elect biden. >> i did vote for joe biden in 2020. >> do you plan to vote for him in 2024? >> i do not. >> i will gladly turn in an empty ballot. >> reporter: if the election would be to held today and president biden is on the ballot and we have to go out and vote today, i can't promise that he will get five votes from arab americans in the city of dearborn. >> reporter: adam abu salah, a palestinian american, worked on the 2020 campaign as a biden fellow doing outreach to the arab community. >> the man i went out and knocked on doors for, i feel guilty, and i absolutely regret what i did on the biden campaign. when we thought he would be someone who could lead with humanity and compassion, we were wrong. >> reporter: some are prepared to boycott biden, even if it means to potentially hand the election to the current republican front-runner, former president donald trump. >> we are no longer going to consider the lesser of two evils. >> reporter: the white house has pointed to recent reachouts with the arab communities as well as the need for humanitarian pause. and announcing an effort to combat islamophobia. >> that kind of hate has no place. >> reporter: efforts dismissed by the people we spoke with as damage control, adding the only way to maybe save their votes is by calling for an immediate cease-fire. >> enough is enough. we need to cease-fire. >> reporter: michigan is second only to california in residents who identify as middle eastern or north african, according to the u.s. census. in 2020, biden won the state by nearly 155,000 votes. m gauge, a national organization dedicated to getting out the muslim vote says 145,000 muslim mic mic michiganders voted in 2020 z. >> we're not here to prostitute ourself to the lowest bidder. >> reporter: the biden campaign sent cnn a statement saying in part, president biden knows the importance of earning the trust of every community, of upholding the sacred dignity and rights of all americans. president biden continues to work closely and proudly with leaders in the muslim and palestinian communities in america to listen to them, stand up for them, and fight back against hate. but the people i spoke to in this community say if democrats think they'll forget by next november, then they are wrong. this is not political for them. it is personal. these are their friends and family members they are talking about, not just something they're watching on television. their congresswoman, rashida tlaib, posting on friday night a video, where she echos their sentiments, writing at the end, biden, support a cease-fire now or don't count on us in 2024. diane gallagher, cnn, dearborn, michigan. >> now, you heard about donald trump in that report, and the former president was back on the campaign trail on saturday. he dominated the stage at a republican gathering in florida. mr. trump celebrated several new endorsements from local lawmakers in the state, including some of those who had flipped their support from his rival, a republican governor ron desantis. on the stage, former president trump bashed desantis and chris christie, and he also accused of president biden wanting the united states to fail and pledged he would reinstate his travel ban on immigrants visiting the u.s. with his legal woes still writ large, the former president is set to take the stand on monday in his civil fraud trial in new york. the case involves the trump organization. it follows the evidence given by his two sons last week. cnn's brian todd takes a look at the trump children's roles in the trump organization. >> reporter: the trump family business and its legacy now facing what could be an existential test. eric trump, donald jr., and ivanka trump have spent most of their entire adult lives working for their father's company. ivanka no longer works for the company. eric trump oversaw the family's golf businesses before broadening his role in recent years to become the practical leader of the trump organization. both brothers saw their portfolios in the trump organization grow when their father was elected president and handed over the business to them. >> don and eric are going to be running the company. >> he trusts them more than he trusts anyone else and he respects them. and as donald said to me, he doesn't respect very many people, but he sure as heck respects his children. >> reporter: biographer michael d d'antonio say all three children have been effective managers of the trump band, but haven't been tested outside the family business, and he says they honed their marketing skills even before their father's wildly popular reality show, "the apprentice". >> james, do you think it shows fundamental lack of judgment? >> i think that all three trump kids saw what their dad was doing, even before "the apprentice," his ability to manipulate the media is really unrivaled. >> reporter: this week, donald trump's two eldest sons struck defiant tones on the courthouse steps, after testifying in a civil fraud case brought against the trump organization, by new york attorney general letitia james. >> unfortunately, the attorney general has brought forth a case that is pourely a political persecution. >> we haven't done a damned thing wrong and they drug don and i in it as collateral damage. >> rep
