[ bleep ]. >> sadly that are attempts to stop the show appear to be ignored. cnn spoke to two concert goers say they've been to several travis scott concerts before and they've never seen anything like this. >> teenagers were giving cpr to other teenagers because the medical staff wasn't well equipped to handle this. they weren't -- they didn't know how to do cpr. so people's friends were giving cpr to each other. >> people that were pulled out were actually after they woke up were told to help out and give cpr even though they just woke up from being passed out. >> there was no time to breathe. so it wasn't really i think i'm going -- it was, i'm going to die. i need to breathe. >> exactly. it's not -- yeah, it was more of i can't breathe thing to the point where i didn't know if i was going to make it out of there. >> so, how could something like this happen in the first place? how could so many people get trapped with nowhere to go in such a wide open area? houston's fire chief explained what went into the planning ahead of the concert. here he is. >> when we have large events, one of the things that we consider is to ensure that the crowds are subdivided. they had two separate stages in two separate areas. that was part of the plan. we had inspectors to ensure the means of egress, the doors in and out of that venue were maintained open and unobstructed. what we're looking into is what caused the crowd surge? what led to the crowd surge? and those incidents at the point of the where the convert was at, the stage. so again our role in this is to participate with the police department. we are going to look at the film and the video as the chief mentioned, and we're going to ensure the items that should have been in place were in place and that we learn from this event. >> the company responsible for organizing the festival, live nation, issued this statement. heartbroken for those lost and impacted at astro world last night. we will continue to provide as much information and assistance as possible to the local authorities as they investigate the situation. the founder and head of crowd management strategies joins me from los angeles. thank you for being here with us. when you heard what happened and saw some of the footage from the crowd and so on, what was your first reaction? >> well, i thought this is a classic preventable crowd craze tragedy. a crowd craze is when people move towards something of perceived value. in this case, it's the artist on stage. it's a known kind of disaster that occurs at rock concerts and could have been prevented through proper planning and management of the crowd. >> so before we get into that, i just want to know a bit more about how this happens. take us through the mechanics of how a surging crowd can become so deadly. >> well, a surging crowd becomes really deadly when the crowd capacity is not appropriate. when the crowd becomes too large and they move, like i said in this case n a crowd craze manner, towards something of perceived value towards the front of the stage. this tragedy builds over time. it doesn't just happen. like a lightning strike. it takes time, 20 minutes, 40 minutes, an hour sometimes for the crowd to build. and people just continue to -- if they're not managed properly and prevented from moving forward, they just keep moving forward to get towards the stage. this is done in a crowd festival kind of crowd configuration. crowd festival standing room is the most dangerous and deadly crowd configuration in rock and roll and festivals. always has been. that's why it's so important to manage a festival seating crowd properly. and the promoter and the artist and security and venue operator and those who approved the plan for this festival knew or should have known of the danger of unmanaged festival seating and knew or should have known of national standards and techniques to prevent this very type of disaster. >> what needs to happen to make sure things like this never happen again? >> well, i'll tell you what needs to happen, people need be held criminally liable. the people who plan, manage and approve these events. that's the fact. until they're held responsible these disasters will drone on as they have since the beginning of rock & roll. those responsible for the safety of people in crowds have to follow proper safety futures, which are known throughout the industry. >> and then lastly, you know, f for concert goers, what advice can you give them, dangers to look for, signs like, so this doesn't happen to them? >> of course, people in the crowd. i spent over 15 years to 18 years in crowds just like this. they assume their safety is being looked after, but in fact, there is no safety net. it's hard for them to recognize the dangers. it's not the role of 16-year-old suz si or 18-year-old johnny to be crowd security guard and crowd safety expert. but what you do and what some people are able to do is recognize impending dangers. when the crush is getting serious and breathing is getting difficult. but the fact of the matter is people responsible for the safety of people in crowds are those people who organized the event, managed the event, profit from the event and approve the event. >> let's hope some changes are put into place here. really appreciate your expertise, paul wertheimer, thank you so much. we have more coverage including the latest day or night at cnn.com. the u.s. is condemning a brazen assassination attack at iraq's prime minister. images on iraqi tv show the damage left by the attack. the military says a drone rigged with explosives was used to attack the prime minister's home, interior minister says three drones were involved but two were taken out by security forces. what more can you tell us about exactly what happened and more importantly maybe who might have been behind it? >> reporter: kim, clearly very dangerous, unprecedented sort of development in the situation in iraq overnight as we understand from the iraqi security services, this attack, this attempted assassination took place in the early hours sunday. the prime minister was returning to his residence inside the 45 green zone, that's where you've got several embassies including the u.s. embassy and the iraqi government headquarters. he was out visiting troops, guarding the green zone, when he returned to his home. that is when this strike with a drone laden with explosives, we understand, as you mentioned iraqi security forces are saying two other drones were taken down but one hit the prime minister's residence causing extensive damages we can see and according to officials a number of his security detail were injured in this incident. now, so far no one has claimed responsibility for this attack, this brazen attack. but, as we've just in the past few moments gotten a statement from iraq's national security council, they are blaming what they describe as criminal armed group. they say those groups have misread the government's restraint and professionalism as weakness. and that they are targeting now the iraqi government and its symbols. the government they are vowing to investigate and hold accountable whoever is responsible. the term armed criminal groups is a term iraqi officials in the past have used to describe the iranian-backed militias in the country. these are the groups of people would suspect are behind these attacks. they carried out these sort of drone strikes targeting u.s. bases in the green zone in the past, but these groups, several of them, the most significant hezbollah all releasing statements in the past few hours basically distancing themselves from this attack, saying they had nothing to do with it. even questioning whether this attack even took place. some are calling for independent investigation into it saying that this is basically trying to set them up and start chaos in the country. now, kim, we need to keep in mind what has been going on in the leadup of this assassination, tensions have been so high in iraq since october 10th elections. these iranian-backed groups emerged as the biggest losers in that election. they lost a lot of the seats they had in parliament before and they have been refusing to accept the results of the elections that they've described as fraudulent elections. we have seen their supporters for weeks protesting outside the heavily-fortified green zone. and on friday, that turned violent as the supporters of these groups tried to storm the green zone, clashed with security forces and at least one was killed and dozens others were injured in other serious escalations. a lot of concern about how does iraq step back from the brink after this serious escalation, not only that how do they deal with the situation when you have these heavily armed powerful groups that the iraqi government in the past has not been able to hold accountable for crimes they have been accused of. and how do they deal with this current situation that is being described by iraqi officials including the iraqi president as an attempt to drag iraq into chaos and a coup against the constitutional process. a very, very critical and dangerous moment that is unfolding right now in iraq, kim. >> yeah. disturbing escalation, as you say. thanks so much. president biden notches a critical win in congress on infrastructure, but now he has to gear up for an even bigger fight on the rest of his domestic agenda. so we'll talk about what's at stake with political analyst ron brownstein. plus a fuel tanker explodes killing dozens. why the deadly accident happened and why it isn't uncommon in the region. a live report from sierra leone coming up. stay with us. ♪ so she talked to her doctor becacause she wanted more relief. that's when she said yess to adding lilinzess. linzess is not a laxative. it helps you have more frequent and complete bowel movemenents. and is proven to h help relieve overall abdominal l symptoms-belly pai, discomfort, and bloating. do not give linzess to children less than six and it should not be given to children six to less than 18, it may harm them. do not take linzess if you have a bowel blockage. get immediate help if you develop unusual or severe stomach pain, especially with bloody or black stools. the most common side effect is diarrhea, sometimes severe. if it's severe, stop taking linzess and call your doctor right away. other side effects include gas, stomach area pain, and swelling. could your story also be about ibs-c?

>> well, there's the potential here this is part of a broader package is really the biggest infusion of public invest frmt the government into the economy since the 1960s, early 1960s as a share of total gdp. the president will be signing a bill that includes big investments in what we historically have thought of infrastructure, fixing bridges and roads, but also in beginning the transition to a clean energy economy with a lot of money p for building ev, electric vehicle charging stations around the country, supporting mass transit. >> president biden touted this rebuild america, blueprint. does this help there in those swing states among the blue collar voters or when it comes to the election will cultural issues? >> the fundamental bet -- one of the fundamental bets politically biden placed if he focuses on kitchen table issues, checks in the pocket, shots in the arm, shovels in the ground that he can win back some of the working class white voters and now some working class hispanic voters who have been drawn to conservative republican message on a broad array of cultural, racial and identity issues. there's no guarantee that it's going to work. but this is going to be the best i think test of this theory which has really been an argument in the democratic party for as long as i've been covering politics for 30 years there have been democratic strategists arguing that if the party can show working class voters that government can deliver for them, can make a positive difference in their lives, that they can win back some of those voters. now, you know, there's a lot in these two packages that will potentially do that. i mean, this does have a heavy tilt, the infrastructure plan toward creating blue collar jobs. when you get to the broader package, things like the child tax credit, child care subsidies, lower healthcare prices, there is an opportunity to make a difference on the bottom line of families. but whether that overcomes the cultural barriers with the democratic party, very much remains to be seen. >> yeah. so this and build back better, i mean, they seem to be coming together in the worst way manageable in terms of process and the narrative is forming it will hurt democrats and the president in the midterms and so on, but is that right? do voters care about prosnesz you made an interesting link something you wrote in 1994 about the way that democrats and the president were putting or the democrats were putting their self interest over president and party and that ended up going pretty poorly. explain the parallels there that you're seeing almost 30 years later. >> right. the broad point is that legislative success is necessary but usually not sufficient to guarantee political success in year two. ronald reagan passed tax cuts in '81, republicans lost seat in '82. lyndon johnson created medicare, medicaid and the voting rights act, they lost seats in '66. obama passed the affordable care act in 2009 and lost seats in 2010. it's no guarantee of success, but it can be obviously a legislative achievement can be important once they have time to kind of penetrate and infuse people's lives. that's why they're often more valuable for a president running for re-election than they are for his party in the mid term a few months later. what happened in '94 was the other side of the coin where democratic divisions ultimately almost derailed president clinton's, bill clinton's, c economic agenda and for a time the sweeping crime bill. what happened was the left and the right of the democratic party each made decisions that they thought were in their logical, self interest, voting against the parts of all of these plans that they thought would hurt them at home. but what they failed to consider is what any management, anybody who has been to business school out there will tell you is called the prisoner's delimb ma, each side increases the risks to all of them. that's what happened. the left and the right all thought they were helping themselves by voting against key components of the clinton agenda. in the end, they cemented an image of dysfunction that hurt them all and that really is the risk to democrats in the way this is unfolded for so many months. they seem to be kind of distracted in their own internal struggles and stalemate while the country is primarily -- wants to see action and particularly wants to see action on controlling covid and getting inflation and the economy more stable. there's a real risk even if they pass this they have discredited to some extent but still much better off doing it than not. >> we'll see if history repeats itself. always appreciate your analysis. ron brownstein, thanks so much. >> thanks for having me. >> ethiopia's government prepares for war in the capital as rebels advance. we'll explain what it's asking for military veteran. plus, greece turns, as much of europe grapples with a surge in covid cases. stay with us. tresemmé's pro pure collection lets you style without compromise. tresemmé pro pure 0% compromise, 100% you. trelegy for copd.

>> i have seen kids pass out before, but usually everyone helps out. but this time people fighting for their lives. i was trying to pick kids up that were getting stomped on. i picked a kid up, his eyes rolled to the back of his head. i checked his pulse. i had to leave him there. there was nothing i could do. i had to keep going. >> even in the midst of the chaos, you were trying to check one else, check their pulse. there was no pulse. what was going through your mind as this was all unfolding? >> it was really frustrating. i wanted everyone to realize what was going on. people didn't have much self awareness. kids were going crazy and partying for the festival and weren't paying attention to the bodies dropping behind them. >> did you feel like as this was unfolding, it was getting really bad, you're there trying to help the situation, that there was enough security guards or people there who were supposed to be jumping in at moments like this to contain the situation? >> no, no, no. there wasn't enough security guard and there wasn't enough emts or people helping out the crowds. the paramedics couldn't reach the kids. the little golf cart ambulance got to us 35, 40 minutes after i saw 10 to 20 people pass away. >> did you fear for your life? did you think you were going to die? you described it as a death trap. is that what you thought was going to happen to you? >> i've been in crazy mosh pits. i knew how to maneuver out. people in there for the first time, they didn't know what to do. it's not -- a lot of these kids are younger kids and don't know what to expect. when i was posting the contact of what happened at the show, i wanted people to see the reality of how these shows can be. it's really dangerous. >> people say the cause of the crowd surge sun known. homicide divisions have joined the investigation. more countries are telling their non-essential staff to leave ethiopia. videos from the state broadcaster show pro-government rallies in the capital as they try to down play. the central government is calling on veterans to rejoin the military and that's on top of a state of emergency that allows conscription with more on the situation, let's bring in melissa bell in paris. melissa, the u.s. has tried to broker peace. they've sent envoys, trying to pressure the government. doesn't seem to have worked and now the u.s. government is telling americans to leave the country. does that suggest a diplomatic solution isn't likely here? >> i think that's the big question especially amid this ratcheting up of nationalist sentiment, the creation of an alliance on one hand of rebel parties at both military and political parties opposed to the government. this morning, this rally that we saw many thousands turned out in support of the ethiopian government and decrying what it -- we saw on the signs the posters held by some demonstrators what the government describes as the international media's false reporting of the situation on the ground and exaggerated importance it's given to the rebel advance. that's the position represented by those who came out in its favor today. but amid that ratcheting up of sentiment on both sides, the entrenching of positions on either side, there is, of course, all of that diplomacy going on behind the scenes. the u.s. envoy extending his stay. he's due today in the kenyan capital for a meeting with the president who in his role as the chair of the east african economic bloc is going to try also to work to some sort of compromise, some sort of aim to try to get all the parties sitting around a table together that talks should happen. i asked just a few moments ago a senior african diplomatic source what the chances were of diplomacy. how much hope is there at this stage that words that negotiations can happen and pull everyone back from the brink of what the u.n. human rights warned could be an all-out civil war. the answer came back that, look, it's a very small window, but the truth is that ethiopia is too big to fail and the alternative simply too bleak to contemplate. >> let's hope a peaceful resolution can be found there. thanks for your reporting. cnn's melissa bell in paris for us. at least 98 people are dead after a fuel tanker exploded in sierra leone. it happened in free town when two trucks collided causing the tanker to leak fuel. journalist joins me with more from free town. so you were there on the scene. it must have been horrifying. describe what you saw and take us through what happened. >> reporter: well, it really was horrifying. it was on friday night. a fuel tanker was apparently going to unload its contents at the gas station and then a truck rammed into this tanker and the nearby, there was a leakage of fuel from the tanker. and there was -- all of a sudden there was an explosion. the fire ball just entirely enveloped the whole area including lots of vehicles which had been caught up in the traffic jam that this accident had brought about. so eventually some of the passengers in their cars were heading home at about 8:00 p.m. in the evening got caught up in this whole inferno which has killed at least 98 people with about 95 still admitted. i'm talking to central morgan free town at the mortuary. the bodies are being prepared for burial. we don't know whether it will be a mass burial. yesterday relatives were called to come and identify their loved ones, but the bodies are in such a state that it was very difficult for them to identify their relatives. we don't know what will happen. the president was in scotland, returned last night and as i talk to you now, he is at the scene of the accident in the eastern town of wellington. he's expected to make an announcement once he finishes the complete tour. >> we're looking at the pictures right now. we can understand as you're saying that the bodies might be too burned to identify. can you take us through, explain why people would be risking their lives to collect fuel like that, which led to this high death toll. >> reporter: well, obviously when it's happened these people were around, mostly young people, who are otherwise jobless. livelihood, survival here is a real hustle for many people. amongst those young people who do this taxi riding. so when they saw the leakage of the fuel, they thought that was an opportunity for them. and videos have emerged from seconds before the inferno, moments before the inferno happened when these young people would scoop the fuel in open containers. take the fuel and store it somewhere. return to the scene, scoop a lot more. the numbers obviously increased. and we yet do not know what led to the explosion. but they were looking for a shortcut to be able to eke out a living. >> gosh. it's not uncommon in africa. i remember a similar incident in tanzania a few years ago that had a huge death toll. in terms of this accident, i know from my time there in sierra leone, the hospital systems aren't necessarily equipped for something like this dealing with so many victims especially after so many healthcare workers lost their lives after the ebola epidemic. so how are they coping with all of the wounded? >> reporter: well, a medical doctor told me this morning they have been surviving all by the skin of their teeth. this is a country, whole healthcare system even in the best of times struggles. so with such a sheer number of victims or injured people being brought into this facility, clearly it's very tough. the mortuary is situated at the country's main hospital. when it happened on friday night, doctors and other healthcare workers were called back, report to duty were able to see patients friday night into saturday morning. even that was very tough for them to go through. the pharmacy was open to them, so there was no need for anybody to buy any drugs. all the drugs are put at their disposal as announced by the central government. otherwise they still are struggling because it's a facility that underresourced even in the best of times. >> it's sad that this country that has seen more of its share of tragedies should go through something like this. listen, we really appreciate you having you on in freetown, sierra leone. thanks so much. >> reporter: thanks. the u.s. has just crossed a symbolic milestone in its covid vaccination campaign. the cdc says 70% of american adults are more than 180 million people are now fully vaccinated. so if you look at the entire population not just adults, it's more than 58%. and you have to remember, children 5 to 11 years old just started getting the vaccine this past week. but, the president's plan to get shots in the arms of more adults is facing a pushback in court. more than two dozen states are suing the biden administration over its vaccine mandate for workers at large, private companies. on saturday, a federal appeals court in new orleans temporarily blocked the mandate saying it raises grave legal and constitutional questions. the government has until monday night to respond. the justice department says it will vigorously defend the mandate. concerns are growing that europe could be in for a rough winter as the pandemic comes surging back. russia is the latest country to see a record number of covid cases in recent days. they reported more than 41,000 new infections on saturday. the virus is sweeping across the continent with at least five other nations seeing record case numbers over the past week. one of them is greece where new restrictions for the unvaccinated went into effect saturday. they are now required to show a negative test before they can go to banks or shops or get access to social services. still ahead from seoul to sydney, people gather around the world to demand less talk and more action from their leaders on the climate crisis. please stay with us. and comes in original prescription strength. salonpas. it's good medicine.
