stories coming in right here to "cnn news central." ♪ any moment now, we expect an update on this weekend's deadliest shooting, and there were several. the district attorney in philadelphia will discuss a case against a suspect in monday night's mass shooting. he says kim brady keraker set out to shoot stranger. he appeared in court today. he will be held without bond, now charged with five counts of murder, five counts of attempted murder, a 15-year-old boy month the dead, a 2 years old boy among the wounded. danny, listening to philadelphia officials yesterday, as they described the details, these words like disgusting, clearly the community is reeling from this.

tell us what we're going to say in court today i. >> reporter: that's right, jim, a lot of passionate remarks from city officials yesterday and this morning. let me tell you about what we saw in cord today. kimbrady carriker, he had a preliminary hearing this morning, only about 15 minutes long, but the laundry list made it feel like a longer time. the charges including murder, attempted murder, aggravated assault, reckless endangerment and violations of laws related to having firearms which you should not be allowed to have them. the magistrate judge made the comment when it came to holding him without bail that public safety is clearly an sure in this case.

the judge added no set of conditions exist in which you would not be a flight risk, speaking to the defendant will. jim, i'll say throughout this entire proceeding, the defendant set in a white jumpsuit, really only one-word answers to questions from both the judge and his federally appointed defense attorney. at this point, the defense is not commenting on this case, but that's the latest here. his next court appearance is july 24th. jim? >> you mentioned among the charges here are involved not having a weapon legally. do we know the details about how he got the weapons? >> reporter: yeah, jim, we're still waiting for details about exactly where the weapons may have come from, the d.a. said one of the weapons may have been a ghost gun and the other was an ar-15. they found that on his body at the time. we're still waiting for more

details as to exactly how it happened, but the district attorney and others in this community have suggested these are likely guns that were acquired illegally. again, i think you can expect to heard more from the d.a. in this press conference starting any minute about the guns. >> you hear from across the country how much more frequently they're seeing ghost guns in shootings. this shooting was in a block party in shreveport, louisiana. cnn's ryan young has been following the latest development in this store. story. >> reporter: this is pure chaos, from everything that's been described to us. so many people were parked down a certain road there. when police tried to respond, they had trouble trying to get to the area. members of the public thought

itto the shooting lasted more than ten minutes. and there was a body found this morning in tall grass, police didn't find the body until first light. so more evidence has to be gathered. this is a fourth of july celebration that's been going on for 15 years, never with any violence. all of a sudden the shots are fired. they're not sure if there's multiple shooters or not. we know that seven people were injured, four people killed in this. listen to one of the commissioners in that community, who is very angry about what's happened in her community. >> you will not get away with this. what you have done is traumatized this community. you have traumatized us in a way that is unfathomable. you have hurt us in ways that we cannot put into words. you have caused us grief. you have caused us pain.

i want whoever you are to pay. >> reporter: boris, you hear the pain in her voice. you can understand why she's so upset. shreveport has reeling from gun violence for the last for a years. right now, you have this police investigation where the please chief was out there, basically saying the next 48 hours will be pretty important. there were people running, losing their keys, couldn't find their kids or family members for quite some people, as people were scattering. so many questions, and we still haven't got an accurate picture. we know community members are calling for drones to go up to make sure there's no additional victims. another troubling shooting in this country. >> ryan young, thank you so much. the biggest nuclear plant in europe is once again on high

alert. president zelenskyy say russia may have platted explosioves. zen can i set putin's forces are ready to carry out an attack, and the u.n. team there is simply not big enough to safeguard the facility. >> i know you've been touring the nuclear plants. you have warned that putin could be prepared to have a terrorist attack on zaporizhzhia. do you feel that could be imminent? >> so, what -- i have it from intelligence. i have documents. i can't tell you what kind of documents, but it's some connecting with russia. i said they were technically ready to do something. it's very important that they

mine -- some local minings at zaporizhzhia in this station. they are technically ready. that's why we pushed iaea, and we pushed them, and we said, look your team there -- there are four people -- and this plant is like a city. it's really like a city. >> it's huge. >> four people will not find mines. >> reporter: that is part of erin's full interview that will air later tonight. >> ben wedeman is here with us. ben, again there's a standoff that has the whole world on edge. >> reporter: trahat's right.

they are trading accusations that the other is about to do something sinister. as you mentioned, president zelenskyy said in his nightly address, that intelligence indicates that russia as planted explosives on some of the roof of the power units, the implication that the russians will try to create, essentially a false flag. the russians, on the other hand, say, no, it's the ucrannance that are thup to no good. in fact, peskov said there's a threat that could have catastrophic consequences. in the middle of this is the iaea, who has inspectors on site. we're not clear how many there

are, but they said there's no visible proof at this point that any explosives have been set at the site. however, they did put out a statement today, say that iaea experts have requested additional access that's necessary to confirm the absence of mines or explosives at the site, in it can't heart access to the roofstops of reactor units 3 and 4 is essentially, as well as parts of the turbine halls, and some parts of the cooling system at the plant. over the last week or so, we've had heard more and more claims that the russians have put mines in the cooling ponds, and explo explosive-laden trucks outside the reactors. i suppose at this point we should wait for tiaea to find ot

what they have discovered. what's happening in bakhmut. >> they say they're taking ground on a small village on the outskirts of bakhmut, but they continue to grapple with the fact the russians have a lot of artillery, far better airpower in the oarea. the strategic goal is to encircle the city of bakhmut, so they're trying to approach from the north as well as the south. it seems they're having better success on the southern axis, but they have conceded fighting in the north is particularly difficult. >> ben wedeman, thank you. let's expand the former

conversation with william taylor, also the vice president for russia and europe at the u.s. institute of peace. always great to get your perspective on these matters. let's start with zaporizhzhia. how likely is it we'll see a nuclear disaster. >> boris, they're putting out the word in or to deter that. they of course don't want a nuclear disaster on their own territory. the russians have a hard time making the case they should be believed. of course, these are the russians who said they weren't going to invade ukraine. >> right. >> now they're saying they won't do anything, so the question is, who will you believe? right now, i think you have to believe the ukrainians. >> from a diplomatic perspective, there is anything the iaea or the west could do to calm the situation down? >> they could put pressure a

president putin dodd what he should have done a long time ago, which is pull his troops out. that's the call of all of this damage, all the killing. if you were to pull his troops out, that would calm things done. the chinese could do some of that. you're right to point out there are people who have influence on president putin, and they should use it. >> president xi of china reportedly warned putin about is the fallout of a nuclear -- is there a diplomatic angle to bring calm to the situation, yew -- using xi, for example? >> the chinese can lean on president putin. they can't cause a negotiation to take place. it's between the ukrainians and the russians. that doesn't seem to be on the

cards on either side. complicating things is the fact that vladimir putin had to just stomp out an attempted coup. does that make him more dangerous, that he now has to show force? >> he's probably looking to see who he can trust and can't. there are reports that some of his own generals were associated with the mutiny attempt. >> i want your perspective on the progress in the ukrainian counter-offensive, specifically bakhmut. russia has send troops to the eastern front, yet we have seen mixed results. does russia need a landmark victory, as it's faced so many

step backs. >> the ukrainians are still in phase one, looking for weaknesses, looking for strengths. they're looking to see if there's 180,000 troops. if they're there, they're not going to try to break through there. ukraine will look for where it's weak. that's what they're, they don't have any success and they don't look like they're going to have any. because of a prolonged stalemade, we may see the cease-fire that he has reportedly says he wants. >> that cease-fire is possible once they've pushed the russians out. he needs a breakthrough, find that weakness, break through the russian line. once they push the russians out, that's the time. >> the question is, push them out to where? does that include crimea?

privately reportedly he's said some things, but publicly others. always appreciate your expert. >> of course. a u.s. official says the navy foiled multiple attempts to seize two oil tankers in the gulf of oman. iran apparently opened fire on one of those tankers. cnn's oren liebermann has been speaking to several sources at the pentagon. does the u.s. believe the threat is gone now? >> look, jim, we've seen attempts that iran has successfully seized commercial vessels in the past. i don't know if we've seen attempts this close together, though. the first incident ekurd in the

gulf of oman. the u.s. navy says an iranian navy ship approached an oil tanker, the navy deployed a destroyer and drone, and according to that, the iranian vessel changed course and left the scene. but it didn't end there. only three hours later, another iranian vessels approached a different commercial oil tanker. in a moment we'll zoom out, and you can see it in the top right of the screen. personnel on board the iranian vessel opened small weapons. you can see what the navy says are the ricochets of those shots off of the hull of the oil tanker there. nobody was injured, according to the u.s. navy, but the shots

that were fired did impact and hit and cause damage very close to the crew living quarters. it was the same u.s. navy des destroyer that responded, and again the vessel turned and left the scene. in april and may, two were seized in a matter of days. it was after that that the u.s. deployed more ships and aircraft to the region, specifically to monitor this sort of activity, in the strait of hormuz and gulf of oman. the question is, where does this go from here? >> it certainly affects the lives of the crews there, but also economic effects. oren liebermann, thanks so much. brianna? let's go to philadelphia, where the district attorney is

speaking about the mass shooting that happened on monday night that claimed the lives of five people. >> i'd say that's about right, the bullets don't care, but we do. i know the rest of the city and the country cares. i want to identify some of the good people who are here today, many of whom will be speak. ada joann pescatore. and the prosecutor assigned to this case from the beginning. ada bob wayne wright. we have the ref render here, who has done an incredible work to reach out to victims, survivors,

co-survivors affected by this disaster. and we have the administrator manager of the cares unit, the subpart of the victim witness unit in the d.a.'s office, specifically task with working intensely in the first 45 days. just imagine for a second what its it's like when you can't afford a funeral, what it's like when you feel in danger, what it's like when all that grief is crushing you and causing health problems. imagine what it's like to have a immediate logistics, and trying to address your own trauma. that's the kind of work that's done by reverend maxwell. we also have shoulynn harris, specifically working in our unit and specifically working on this

particular case. anthony brown, ant brown is here for abrow, an organization that works in schools. a lot of juveniles have been affected directly and indirectly by this. we appreciate his being here. we have several members of the lgbtq plus liaison group, some of whom are also victim witness coordinators, including kellie burke burkhardt, in addition for filling in role. we have asa caliph, who -- i mean, frankly i shouldn't have to introduce him. our sheriff is here.

senator street of p.a. center district 3, who has done so much to try to address issues of gun violence and prevention around gun violence, is here. we have dr. zaf qasim, a medical doctor and emergency physician, from penn presbyterian medical center. he is here with registered nurse stephanie porten, who also worked in emergency, and both of these individuals have come here to tell you what it was like to treat many of the injured in the emergency room on the night it occurred, and to speak more generally about the reality of their everyday situation is gun violence victims coming in for years. dr. qasim has been doing this

work for eight years here, but a doctor for 22 years. we have with us vovif director the acana, the african cultural alliance of north america. the offices are very close to where the incident occurred. some call him the mayor up here, the mayor of that neighborhood. he's played an important role in assisting the d.a.'s office,. he is present, senior pastor of the church of christian compassion, who has collaborated for many times, and among other things is dealing with one of the families to deal with the most traumatic aspects.

we have iman kenneth ordean whose constant work is constant. and the ref right-hand dr. shawn james here it is salt & light church, who is our host. we also hthe two sisters of one of the victims. if they are able, they will speaking today. if they are not able, you will understand. let me say a couple words before we hear more from the community. action many who are aware, a lot came to the scene of the crime yesterday, within several hours of the shooting. my office at that time had fully

deployed our cares team, our coordinators' team, who immediately got in contact with the families of all of the victims. with the exception of the one young man who had not been identified at the time. as soon as he was identified, they kicked into gear to address that. while we were out at the scene yesterday, we were accompanied by leader joanna mcclinton, the speaker of the pennsylvania house, representative jordan harris, who is essentially her right hand, the number two in the pennsylvania house for the democrats. council members catherine gilmore richardson was there, council men jamie gottier was there by phone. she was a couple thousand miles away, but wanted to know everything going on. the reverend was there as well,

and we're all struck by many things, but just one of those things was the bicycle, which is still there. i don't know if you saw it, but right at the corner where this all went down yesterday, 24 hours -- actually 28 hours ago there was a small bicycle looked like a small child's bicycle. we were informed by some people who were there that that bicycle was dropped by someone, i presume a child, during the shooting. hours later, nobody had touched it. a nice little bike. hours later nobody had touched it, as if they all felt they couldn't, that it was a memorial, some kind of silent memorial. well, it's there now. it's been moved a few feet, maybe somebody came along and somebody else told them to put it back. it's there now. i think that that fact, the

decen desolation, the curtains closed, the doors locked in that neighborhood, and also the comments from neighbors, the ones who did come out, how close they came to being shod t. those are the things we heard. obviously this office is 100% committed to the vigorous prosecution of this mass killer. we will do justice in court with this case. it's not my time to keep talking. i want to call forward? people who have, in my opinion, very important things to say. its my pleasure, my honor first to call zaf qasim, m.d., as well as registered nurse stephanie horton to speak. we're listen to the district

attorney, larry krazner, talking about the mass shooting that o

new information about the powdery substance found on sunday at the white house, that lab results confirmed was cocaine. kevin, is there anything else that we know about who this

belonged to, or how it got where it was left? >> reporter: those are all questions the secret service is working very urgently to try to find answers to, of course, poring over video, and visitor logs to try to figure out who brought in cocaine. it was found at an entrance to the west wing, so, of course, a heavily trafficked area of the building, not just by staff, but also by tours that staff are allowed to bring through the west wing on sunday. so you can imagine there's quite a number of people who this could be, but that area narrows down who the cocaine could have been belonged to. guests are asked to leave their cell phones before they proceed into the rest of the building. the other question i think officials are trying to find an answer to, when it was brought in. it was found on sunday on a routine patrol by secret confess

off service officers. so, of course he they did the field testing on the substance on sunday night. that came back for cocaine. lab test has also now come back for cocaine. the white house itself has not necessarily wade in on this yet. they are leaving this to the secret service, who are very busy conducting their investigation. >> was it locked in one of the boxes with the cell phones? left on a flat surface for anyone to do? what do we know? >> reporter: officials haven't necessarily said exactly physically. found. we know it's in the entrance to this building, but interestingly, as i said, people can take tours there you this area -- not everyone. it's not open to the public, but it is open on the weekends to

guests of staff, and they are asked to leave cell phones. you can imagine people fumbling with things, where they dropped it. it would be a narrow scope of people going through this area. >> kevin liptak, thank you. what we're seeing in airports across the country, that's coming up. 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 on a fixed bget, remember the three ps. what are the three ps? rethe three pshree ps. of life insurance on a fixedudget are price, price, and price. a price you can afford,

low. 165 cancellations just now nationwide. yesterday for the full day, about 400 nationwide cancellations, but think back to last tuesday when 2200 flights were canceled in total. listen to scott kines. he says it's looking better than last week. >> never just assume everything is going to go great. have a backup plan just in case, but i think your odds are better of an on-time arrival this week than last week. >> reporter: faa is warning of ground stops popping up in denver, charlotte, atlanta today, the big thing tounder score, if you're driving, leave early. aaa says before 2:00 p.m. is the best time, between 3:00 and 6:00 will be the worst time.

so, it's critical to tell your doctor about all medicines you take, including herbal supplements, because lab tests or changing the dose of your medicines may be needed. tell your doctor if you have any serious illnesses, allergies, liver or kidney disease, are pregnant or plan to become pregnant, are breastfeeding, or use birth control. paxlovid may affect how your birth control works. don't take paxlovid if you're allergic to nirmatrelvir, ritonavir, or any of its ingredients. serious side effects can include allergic reactions, liver problems, and issues with hiv medicines. other side effects include altered taste, diarrhea, high blood pressure, muscle aches, abdominal pain, nausea, and feeling unwell. if it's covid, paxlovid. ask your doctor or pharmacist if paxlovid, an innovation from pfizer, is right for you.

there is emerging research showing for certain cancer patients scaling back on aggressive treatments could have some benefit. it's an approach called de-escalation. let's discuss with jacqueline howard. you spoke with some oncologists who say this has shown a benefit to their patients. >> reporter: that's right. some of the oncologists i spoke with said by scaling back aggressive treatments for patients who have less aggressive cancer was able to help their patients not suffer so many serious side effects. so the patient had a nice quality of life was continuing the necessary treatments for their cancer. one example i can share with you, there was one study on rectal cancer patients. researchers looked at patients who had only chemotherapy before they underwent surgery. they compared those patients with patients who had chemo and radiation.

the researchers found similar outcomes. among the patients who had chemo, but skipped radiation, about 80% were disease free. among those who had chemo and radiation about 78% were disease free. the same percentage were decease free. those who only had chemo didn't have the side effects from radi radiation. oncologists said you have to weed out which patients have a less aggressive form of cancer and which patients could possibly benefit from scaling back a little bit on the aggressive treatments. that's kind of the takeaway here. >> really is significant research. jacqueline howard, thank you. we're continuing to follow a developing story. the defense department says the u.s. navy intervened to stop iranian navy ships from attempting to seize two oil tankers in the gulf. we have new details next.
