celebrations across the country. a dangerous round of violence in the middle east. israeli forces launching what they call retaliatory air strikes in gaza. this just hours after wrapping up a major military operation. and republican presidential candidates are on the road again. rallying support from voters in key primary states. we're live with the pence campaign and following these major developing stories and much more. i'm sara dieder in with john berman and kate bolduan, you're watching "cnn news central." it was a violent holiday weekend across the country. the fourth of july block party in louisiana is the latest target. three people were killed, seven others were injured, when gunfire rang out at sleeve port's july 4th celebration. in philadelphia the suspect accused of randomly shooting at victims while roaming through a neighborhood is expected to appear in court for the first time. five people were killed in that

rampage monday night. the youngest victim was just 15 years old. a toddler and a 13-year-old were also hurt after being shot multiple times in their legs. cnn brny din grass and ryan have the latest for us. what are you learning? >> we're still waiting for video from that scene but what we're told this was pure chaos. the shooting happening at a block party for the fourth of july. people were running separated from their children and families, dropping their keys, stopping some of the first responders from being able to get in because cars couldn't be moved. what we're learning so far, three dead, seven injured and the big update right now, we're expecting a news conference around 11:00 a.m. eastern to give us the information about this. now i can tell you shreveport has been dealing with crime and gun violence for some time, and this increasing gun violence in that city has put a lot of pressure on the police department. i can tell you neighbors in this area have told us before, have

talked to cnn, about the increasing gun violence in this city. at that block party no one is sure what set this off and how many shooters there were or the motive of this crime right now. we know people started running, shots were being fired. again, sen seven injured and three a dead. hopefully we'll get more information on this. another shocking amount of gun violence nin this country. >> ryan, stay close to this and we'll have an update on the show. let's talk about philadelphia. today, the suspect in philadelphia is going to be in court. what charges are they facing? >> yeah. you know, kate there are a number of charges that this suspect is now facing. 34 counts in total, five counts of murder, attempted murder, aggravated assault, reckless endangerment. that suspect identified this morning by kimbrady carriker. what authorities say happened

was early in the evening on monday night about 8:30, this suspect just went down the streets of philadelphia into this one particular neighborhood firing an ar-15 weapon while also wearing a bulletproof vest, wearing a ski mask, carrying a scanner, just firing inchris crim nately at different victims. they don't believe at this point there is any relation between the victims and this suspect. we learned from the district attorney there that also they believe the suspect was also carrying a ghost gun in addition to that ar-15, the guns obtained illegally. there are five people that were killed. the youngest of which was just 15 years old. one mother telling cnn affiliate that her son, her youngest child, 20-year-old, was also killed. he was just going to a local store to buy a candy bar. we also know that there were two 2-year-old twins that were killed just in the back seat of a car that they were driving in with their mother.

one shot several times in the leg and is in stable condition along with a 13-year-old as well. i want you to hear from local officials in philadelphia about the shooting. >> i am frustrated and outraged that mass shootings like this continue to happen in communities across the united states. this country needs to reexamine its conscience and find out how to get guns out of dangerous people's hands. we're begging congress to protect lives and do is something about america's gun problem. >> it is disgusting, the lack of proper gun legislation that we have in the commonwealth of pennsylvania. some of that legislation might have made a difference here. >> reporter: 50 shell casings, ar-15 shell casings were recovered at the scene. that suspect is going to go before a judge some time this morning. a news conference about 1:00 is scheduled with the district attorney and others following

that -- likely following that arraignment. >> much more to learn this morning on this one as well. thank you very much. ryan, thank you on that as well. look, kate, in addition to these shootings, nine were shot outside a home in washington, d.c. police are reporting that suspect may have known the victims in this. it could have been a targeted shooting, they say. there were a number of shootings across the country over the holiday. dozens of people killed and hurt. cnn's security correspondent josh campbell joins us now. let's start with what happened in washington, d.c., overnight. what are you learning about that? >> we're learning that as we've seen time and time again where you have gun violence rocking these fourth of july type celebrations, or you have people gathered together, police say overnight there was a mass shooting there, working to determine the specific motive. the connectivity between the shooter and, you know, obviously, the victims. we've seen time and again that even if a shooter is, you know, in some type of dispute or, you know, trying to settle a dispute

with a gun, oftentimes it's innocent bystanders who are there that are, you know, victimized. we know nine injured including two juveniles. police say they described this as some type of drive-by shooting and the manhunt currently under way. >> you have contacts with law enforcement all around the country. what types of things do you hear when people talk about solutions? >> well, you know, this is so important because we talk about these issues time and time again, but, you know, you talk to those who are on the front lines of responding to these shootings and they fault both republicans and democrats. i'm not in the business of both sides without merit, but you look at republicans, i mean, law enforcement still is, you know, concerned about this attachment to guns, particularly these very deadly weapons that we've seen, these high-powered assault style rifles used in the deadliest mass shootings across this country. meaningful legislation on that doesn't move forward. there are people out there who are strong supporters of the second amendment, but you hear

from police chiefs especially across the country saying look, it's our officers who are on the frontlines on the receiving end of some of these bullets. after these shootings we hear republicans talk about mental health, these are mental health issues, but we haven't seen, you know, meaningful legislation really addressing those kinds of issues. and then on the left, i mean there's criticism as well. particularly with progressive d.a.s, the philadelphia district attorney was on cnn this morning talking with our colleagues phil mattingly and poppy harlow, and he was focusing on i'm prosecuting shootings, i have resource issues and i have to prioritize but there's been criticism about what about prosecuting those illegally possessing weapons in the first place, getting ahead of potential crimes and violence. that is certainly a concern we've heard as well. the police don't want to just be waiting around to stand over dead bodies after the shootings happen, but go after people in advance, even if they're lower level crimes, we've seen crimes escalate. there are things to be done across the board according to law enforcement officials for

folks on both sides of the political aisle. >> thank you so much for being with us this morning. appreciate it. >> israeli military forces have launched more air strikes this time in gaza. the idf says the strikes are in response to rocket fire from palestinian militants there. the new round of violence i erupting hours after israel said it completed the largest military operation in jenin in 20 years. take a look at the video of troops leaving jenin in the occupied west bank. the palestinians say the israeli operation left at least 12 people dead and more than 100 others injured and this morning, we have new images of the community preparing a single grave for all 12 of those killed in jenin, among those a 16-year-old boy. we're live on the ground in jenin where the raid cut power, water and internet to the people living there. what are you seeing and hearing from your vantage point?

>> i just want you to take a look at the utter devastation around me and you are looking at me from an overhead shot because of the reasoning you said. there is little infrastructure functioning right now in jenin. my cameraman is perched on a balcony to get you a signal while i'm here on ground level just look at these piles of rubble. this is one of the main thoroughfares. if you can look at it now, it is completely torn up. the street has been turned to mud. you might see the flow of people, there's some u.n. workers just behind me here, all throughout as we've been walking through. you can see united nations workers, red crescent workers, ngos trying to provide the help in support. one ngo worker told me 7,000 to 8,000 people have been made homeless by this raid. it's not until today that many are coming home to find out what's left of their place. i want to point out this vehicle that's here. you can see the sheer force, the sheer power, of this raid.

the strongest, the largest military raid by the israeli army in 20 years. it says the israeli military says it was here to take out terror infrastructure, it was here to neutralize weapon sites that this place was being used as a terrorist haven. for many of the families and residents who live here, it is one of the most densely populated, impoverished corners. they feel they're simply innocent and caught in the crossfire. sara? >> can you tell me, selma, what you're hearing from people? as you mentioned, israel says look, we were going after terrorist targets that have attacked israel, but there has been a call for retaliation from some of the palestinian militant groups. what are you hearing in jenin in on that? >> reporter: what's so extraordinary, sara, especially when you look at this devastation across here, is

there is so much resistance, so much anger, so much defiance coming from jenin camp. earlier today, remember, everyone came back to the camp today, earlier today these streets were packed with a bur burial, thousands of people chanting in the streets that that blood will not be spilled in vain, that they will continue to fight, they will continue to retaliate. what was more extraordinary to see many of those armed palestinian factions that the israeli military says it was targeting, they were sleeping through these streets, armed, shooting gunfire, saying this is defiant. i spoke to residents who, believe it or not looking at this here, were telling me we won, this was resistance. that's the cycle of violence that means families could be caught up in another round n another raid. remember the israeli military said this raid is over, but it reserves the right to attack again and with these palestinian

factions saying they are up for that fight, sara, it's hard to imagine how life doesn't get more difficult here. >> yeah. you mentioned the fact how densely populated this particular area is, jenin, and the west bank there. salma abdelaziz, thank you for giving us a look at what has happened since the raid by israel ended. >> that was an extraordinary vantage point, wonderful to have salma there. terrific reporting. are russian explosives now trapped strapped to europe's largest nuclear plant. the urgent warning out of ukraine. mike pence, focused on iowa, but the past, especially the 2020 election outcome, trails him wherever he goes. and just plain hectic, airports expecting a heavy rush of travelers heading back from their holiday weekends. which airports are seeing the greatest delays? we'll tell you. & foster® using the finest materials, like indulgent memory foam,

on our radar this hour, a sentencing hearing years in the making will soon get under way. the federal sentencing for the gunman who killed 23 people at the el paso walmart in 2019, patrick crew sis pleaded guilty in february to 90 charges, half of them federal hate crimes. authorities say that he carried out the attack with the sole intent of killing immigrant and xe mexicans. he will not face a death sentence but has agreed to accept 90 life sentences and he will face victims and their families today in court. former smallville actress alison mack has been released from prison. mack a high ranking member of the group nextum, claimed to be a self-help organization but prosecutors say women were branded and coerced into having sex with the group's leader.

the founder was sentenced to 120 years in prison. mack pleaded guilty to rack tiering and conspiracy charges. at the time the judge called her an essential accomplice. anded a terrifying ending to a fun day at a festival. just look at this. a mechanical glitch on a roller coaster left eight riders stuck upside down and stuck there for hours. this happened in northeastern wisconsin on sunday. authorities there say the roller coaster stopped mid-loop and because of how high they were stuck, sperp special equipment and trained teams to be had called in for the rescue, leaving riders suspended upside down in their seats for three hours. they were all safely rescued. one person was taken to the hospital. yikes. thank you, kate. this morning an urgent warning from ukraine president zelenskyy who says objects that look like explosives have been found on two nuclear reactors in

zaporizhzhia, and he says russia put them there. the zaporizhzhia power plant is europe's largest nuclear plant. russia has occupied the plant since the beginning of its war in ukraine. ever since there has been a grave global concern that russian forces could carry out a catastrophic nuclear attack. zelenskyy's direct message to moscow right now, the world sees and the world is ready to respond. cnn's scott mclean is in london for us tracking this threat. scott, we've heard from zelenskyy on this, but russia also has its own version of events. what are you hearing? >> yeah. zelenskyy says the only threat to the planet is the russians. the russians say they are no threat at all and said the international atomic energy agency they have inspectors and employees who are working at the site right now, and it was last week that iaea put out a statement saying they seen no evidence of any bombs or mines located on that site, though the caveat is they say they still

would need more fuller access to the site itself in order to say that with 100% certainty. the russians say that look, the threat here is from ukraine. dmitry peskov said this, and i quote, earlier today, there is a great threat of sabotage by kyiv which can have catastrophic consequences. for the record, sara, president zelenskyy isn't putting out any specific evidence of his allegations here, of these explosives on-site, but he's saying that this would essentially be a false flag operation, echoing what ukrainian military has said before in that an explosion would make it look like this was the result of ukrainian shelling but wouldn't be powerful enough to damage the reactors themselves. the ukrainians say that their emergency services have been preparing for this kind of possibility, special forces from ukraine are on alert as well, and the russians say they are prepared for this. everyone here is on high alert.

i just want to show you a satellite image to better illustrate this as well. the reactors themselves, you should be able to see on the top of this image, those red circles there, they're housed in these containment ildings which are designed to be able to withstand the force of aaccidental plane crash. how they would hold up against the weaponof war, we don't have a good answer to that. but also keep ind that bottom of your screen there, you see those rectangles, the dark rectangles are cooling ponds which store the spent nuclear fuel rods and they are right out there in the open. they have no protection at all. there's not a whole lot of margin for error we're talking about here. the good news is that we are getting some reassuring signs from nuclear officials on both sides of the front line, the russian backed officials and occupied parts of ukraine where this plant is located say the background radiation levels are normal, they also called

zelenskyy's claims garbage. one other thing to mention, sair, that is that the kremlin is denying a report in the "financial times" that chinese president xi jinping had warned russian president vladimir putin against using nuclear weapons in ukraine. the kremlin calling that report, quote, fiction. sara? >> i think that's where you're hearing zelenskyy saying the world is watching. thank you so much for all of that, scott. let me give you a sense of where this is taking place. the zaporizhzhia nuclear power plant is right here. that has been in russian hands since the beginning of the invasion. zaporizhzhia, the city, is still in ukrainian hands and has been since the very beginning and a great deal of the fighting and the counteroffensive has been happening along this right here. i think you can see, you can't from where you are, in yellow, these are the towns and cities that ukraine has taken back in the counteroffensive where they have made some progress. let's bring in retired u.s. army

brigadier general steve anderson. great to see you. i want to put up pictures again of the zaporizhzhia nuclear power plant. how much of a disaster would it be from a strategic standpoint if russia did sabotage this plant? >> well, thank you, john. this would be a huge disaster operationally and strategically. i mean, it's -- there's some of the richest farmland in the world is within 50 to 100 miles of this facility, the largest nuclear power plant in europe, and that is incredibly impactful on the world food supply, potentially, not to mention a threat to loss of life and what not. this is why the international atomic energy commission has to absolutely step up, get inspectors on there, and confirm or deny the state of the interp situation there. the other thing pointed out by operations on the ground retaking zaporizhzhia is a high

priority for this ukrainian counteroffensive, so they, too, need to step it up. vladimir putin is desperate. we saw what he did, his reaction, to the recent wagner group defection. he's becoming increasingly vuller in internally, and so -- vulnerable internally so there's no limit to what this desperate man might do. he's taken out the dam that has the potential to impact some of those six reservoirs that scott pointed out and the facility. this is -- zaporizhzhia is a pressurized water reactor. chernobyl was a graphite moderated reactor. what that means is they need water, they need water and cooling towers and containment facilities and all those things are made out of concrete and weapons of war can take down those concrete structures. this is a grave threat, and we need to step it up, the international atomic energy

commission and operationally on the ground. >> in addition to the concerns over the nuclear power plant down here, we've seen a great deal of activity in the country's east. the ukrainians are reporting that russians have deployed 120,000 troops up here, and an additional 15,000 troops around bakhmut and overnight, we saw images, not far from bakhmut, makivkov there was an attack with extraordinary video. the ukrainians launching this attack on the russian held area right there. when you look at this and you take a look again at the map, what's the importance of this region we're looking at here? >> well, it's hugely important, john, potentially this could be a weak point in the live. we're talking a 600 miles front. we're talking an area that's been occupied by the russians now the size of the state of pennsylvania. so they've got to conduct some kind of a penetration, you know,

to get through the weakest point in the line and then hope that they can conduct some kind of flanking maneuvers. my problem with -- it's going to be difficult fight. as you say, a couple hundred thousand troops dug in for over a year preparing, you know, tank mines, all kinds of mine fields, all kinds of tank ditches. it's very, very difficult defensively. they don't have air superiority. we in the united states would never conduct an offense without air superiority. they don't have the long range artillery or the equipment they need or probably don't have the manpower they need. this is very difficult fight. they have to find place like that in the line, a weak point, and then hope to conduct a penetration and successful envelopment and hope the russians surrender in mass because they cannot go toe to toe with these guys. >> always great to have you. thank you so much for your expertise. right now, former vice

president mike pence is about to hold a campaign event in the key primary state of iowa. he's attempting to draw some sharp lines in this moment between him and his former running mate, donald trump. how successful is he doing that? we'll have a look. a trump appointed judge just blocked the biden administration from communicating with social media companies over certain content, but how far could that go? we'll be right back. rude. who are you? i'm an investor in a fund thatat helps advance innovative sports tech h like this smart fitness mirror. i'm also mr. leg day...1989! anyone can become an agent of innovation with invesco qqq, a fund that gives you access to nasdaq-100 innovations. i go through a lot of pants. before investing carefully read and consider fund investment objectives, risks, charges, expenses and more in prospectus at invesco.com. i'm jonathan lawson here to tell you about life insurance through the colonial penn program. if you're age 50 to 85, and looking to buy life insurance

right now, former vice president and now presidential hopeful mike pence is continuing his three-day campaign blitz through western iowa. pence spent the fourth of july

holiday meeting with voters and walking in the urbandale fourth of july parade. he's set to make campaign stops today. cnn's key young law has been following the pence campaign and he's hitting three more counties including where you are in sioux city. from what you've seen and what you're seeing, what does it tell you about his iowa strategy? >> reporter: well, the campaign seeks to try to reach all 99 counties. they want to do what's known in presidential politics here in iowa, the full grassley, chuck grassley referencing, trying to get to every county, every cafe, do the hand-to-hand retail politics in order to get them across the finish line and to make a mark in iowa. mike pence says in his own word hess is known well, but he is not well known. of course, he's well known as trump's vice president and what he wants iowa caucus goers to

think of him, is as his own person. he's at a breakfast meet and greet today. yesterday we saw him almost running through a july 4th p parade as he tried to shake hands, kiss babies and do what you expect on the independence day. then he spoke to a rural community about energy. much of that. he's going to be at an ice cream shop. he's trying to get at the ground level. it is something he's committing himself to, and something that he says his former president, his former running mate, donald trump is not, because he's not here this week. he was specifically asked about trump's lack of presence here. >> i can't account for what other campaigns decided but for me it was vitally important to be here where the journey to the white house always begins and to spend two miles at times jogging uphill to take our case to the people of iowa and i promise you

we're going to keep running that hard all the way to the finish. >> there in iowa, we'll get back. thank you so much. new this morning, a federal judge has blocked certain white house officials from reaching out to social media companies when they see potentially untrue information circulating online. the ruling is seen as a win for the attorney generals from some republican states who accuse the government of going too far in the fight against covid misinformation. cnn white house reporter priscilla al ra very joins us at the white house. there's a lot going on here that has, too, to do with regulation and speech and private companies. >> that's right, john. it really comes as a blow to the administration, especially amid concerns about misinformation circulating online. now as you mentioned, this was a lawsuit brought by republican states. it's one of many legal challenges that republicans have launched against the biden administration, and in this

case, what the ruling does is it keeps a slew of federal agencies and top officials from communicating with social media companies about taking down, quote, content containing protected free speech. now what it doesn't do, it doesn't keep the administration from curbing illegal activity or addressing national security threats, but, of course, this is a top concern for this administration, as it sees the use of -- well of all these social media companies and sometimes in a way that can spread misinformation. now e white house addressed this in a statement saying, quote, our consistent view remains that social media platforms have a critical responsibility to take account of the efforts their platforms are laying -- are having on the american people but make independent choices about the information they present. the white house saying it is important for the social media companies to take responsibility for this, but it still affects those federal agencies, just some of those for awareness, the white house press secretary as

well as hhs, cdc, doj, fbi. naming some of those agencies why this would be a concern for the administration moving forward. the justice department is reviewing the ruling, so we'll see what follows in the hours and days to come, but certainly a blow to the admin. >> absolutely. of course some of the legal questions involved, how much protection for free speech is there on a private platform, but for now, at least, that's a separate issue. priscilla alvarez, thanks for being with j. coronation number two for congress charles. we will take you there. the holiday weekend may be over, but travel delays and cancellations are sticking around. the faa is warning of possible ground stops at airports today. what to expect. that's coming up. tourists tourists that turn into scientists. tourists photographihing thousands of miles of remote coral reefs. that can be analyzed by ai in real time. ♪

. the head of the u.n.'s nuclear watchdog is in fukushima in japan today discussing plans to release radioactive water from the 2011 meltdown into the pacific ocean. japan's state owned electricity firm says it's out of room to store the treated water which is enough to fill more than 500 olympic pools. japan's government and the international atomic energy agency says the radioactive elements present in the water are at low enough levels not to be harmful and the water will be released over decades. in afghanistan the taliban have ordered all beauty salons closed by the end of the month. the salons have been one of the last places in the country where women could gather outside their homes. gyms, parks and schools have been closed since the taliban returned to power in 2021. the world set a record for heat. on monday the average global temperature was nearly 63

a lot of booing and not my king. i think that was an organized campaign there. interesting about scotland, scotland is a separate nation from england, but it's all part of the uk. this whole event hasn't been led by the palace. it's been led by the scottish government, a national -- which is scottish national party, pro independence, but they're not anti-monarchy. they've absolutely been behind, you know, the pro-independence group is behind this event. there are a set of scottish crown jewels but they became redundant hundreds of years ago but they are closely held by the scottish as symbols of their history. they are the oldest crown jewels in the entire british collection, and they are there and representing scotland and it will be presentsed, this crown, which goes back to 1540, will be presented to king charles but it won't be put on his head.

muntean is live at ronald reagan national airport with the very latest. pete, you are smiling so widely. things must be going well there then. >> things are going well. i'm happy the holiday is coming to an end, sara, maybe that's just it, but now is the big rush home for so many people and you can see the group behind me here in terminal 2 at the check point at reagan national airport. has been really busy all day. the tsa screened 2 million people yesterday, 2.2 million people the day before that. that is the slump because those days really fell on the holiday. think back to last friday when the tsa screened 2.88 million people at airports nationwide and that's the highest number tsa has recorded ever and now is the start of the big test part two for airlines, the sequel as all of these people begin coming home all at once.

the good news right now is that flight cancellations have remained relatively low. just checked flight aware. we just hit 100 cancellations in the u.s. today. yesterday for the full day it was 450, but think back to the previous tuesday when airlines canceled 2200 flights in total. they were really struggling with the weather. un united airlines especially was struggling the most. i want you to hear scott hines who said this week is going better than last week. >> never just assume that everything's going to go great. have a backup plan just in case, but i think that your odds are a lot better of an on-time arrival this week than they were last week. >> one caveat to all of this. the faa says there's a possibility of groundstops as the day goes on in some pretty big hubs. we're talking denver, charlotte, atlanta, miami, orlando, so we

will see as the thunderstorms build, there is a bit of good news here in that most people are drive according to aaa. about 42 million people are driving 50 miles or more over the holiday period, they say. the best time to leave is now, before 2:00 p.m. the worst time between 3:00 and 6:00 p.m. this evening. so start to pack your bag and also pack your patience like you said, sara. >> i just want to let people know that pete muntean is not a hater of holidays it's just that you have to work every single holiday so we understand you, pete. thank you very much. >> you're too kind. pete hates holidays. that's the takeaway from all of this. pete muntean, the hater of holidays. we'll check in with pete throughout the show. emerging research shows for certain cancer patients scaling back on aggressive treatments could actually provide some benefits without hurting their chances of survival. it's an approach called de-escalation.

let's get to cnn's jacqueline howard. she has more on this. jacqueline, what are the benefits and what does the research show about this less is more a prech? >> kate, patients can avoid the serious side effects that can come with treatments and they're looking at which therapies may be unnecessary for the less aggressive cancers and one example of this in bone study, researchers looked at rectal cancer patients and looked at those who only received chemotherapy and compared them to those who received chemotherapy and radiation. the patients who received only chemo still had among them 80% of them were disease-free five years later. you see on the screen here, among those who had chemo and radiation, 78.8% of them were disease-free five years later. so you see, there are still similar outcomes among those who just had chemo, but skipped the radiation aspect and that's one example of where doctors are seen as we prepare treatment

plan, where can we scale back on the more aggressive therapies that can lead to life-altering side erck effects and still see positive outcomes. that's the takeaway, kate. >> in the research they say there are certain types of patients or certain types of cancers where this type of scaling back is not recommended. >> absolutely. this is where you really have to personalize your approach and one example, i spoke with an oncologist who treats head and neck cancer patients and she said those patients whose cancer associated with hpv. those cancers are more curable than those not associated for lpv. for an hpv-associated patient, they may try the approach, but not those with cancers not associated with hpv. you have to tease out which patient may benefit and which may not qualify. >> it's interesting.

the nuance on this is a fascinating thing to continue to look at. thanks for bringing it to us, jacqueline. john? >> the suspect accused of killing five people in a mass shooting just appearing in a philadelphia courtroom. we have new information about that case just coming in. for moms, from centrum. ♪ this new mom ♪ ♪ here i go ♪ ♪ i am strong and brave i know ♪ ♪ with a littttle time for me ♪ ♪ no doubt i will get through ♪ ♪ loving me is loving you ♪ ♪ new from centrum. the women's choice multivitamin brand.
