when the gunman entered, and that he managed to stay inside for an hour before he was killed. amna nawaz is in uvalde. and she joins us now. you have been talking to people there all day long. tell us about the questions now being raised abouthe police response. amna: that's right. two days after the massacre here at robb elementary school the pain is still very raw and real for so many here. those mourning the loss of those 19 children and two teachers. but authorities are starting to fill in some details about exactly what happened and when, even as there are a number of details they still cannot or will not answer. a couple of key details they revealed today for the first time, the biggest question was how did the gunman get into the school in the first place. officials say it aears the door was just unlocked. they have been sharing details that they are going through video and additional interviews.

they say that detail could change but right now that is what they believe to be true. the other thing they mention is despite earlier reports that the gunman as he approached the school building was confronted by and engaged by a school resource officer, and armed police officer, officials today say that was not true. there was no engagement, no confrontation outside the school between the gunman and anyone else. officials would not even confirm that there was a school resource officer on site. so it appears we now know between the time the gunman shot hisch grandmother, crashe ande made his way into this elementary school, he did so almost completely unobstructed. judy: and so after tngalo t theu getting a sense of what the main focus is now in the police investigation of this? amna: the biggest question is motive. if the school was targeted, why it was targeted, why these

children in particular. but there are big questions about the timeline that remain, in particular, an hour-long gap. they say the gunman entered the school at 11:40 a.m. and confirmed it was one hour later the tactical teams arrived and were able to enter, engaged him, and killed him. border patrol officials confirmed to me there was a group of what they call a formation of four border patrol officers who entered the building, engaging the gunman, and killing him. but there are a number of questions about why more and other law enforcement officials afthe vent eeredherinut building, why they did not do more. i spoke to some residents who live here around the school, one man in particular who shot video from outside the school with residents yelling at police officers outside of theegging wd pleading with them to do more after hearing the shots fired. a sense of frustration you hear in the video.

that man tells me he shot the video between 12:15 and 12:30, at least 35 minutes after the government openly building. there are a number of questions about why law enforcement did not go in sooner, and if they had, could they have done more to save the lives of those 19 children and two teachers. judy: so disturbing to look at that video which has been circulating. i'm than the vols -- amna nawaz who is in uvalde. w we want to show you the reporting that she filed just moments ago. amna: inhe early morning light of a new day, two rows of crosses stood in frobbf nt amid t rneling, ttahere are new questions about how police responded to tuesday's shooting. in the chaotic scene that unfolded, parents and local residents stood outside, frustrated, as the minutes ticked by. >> you are scared to get shot? i'll go in without a gun. >> we got guys going in to get kids, okay. amna: texas department of public safety regional director, victor

escalon, today said theor mos, appears to have walked into the school unobstructed at 11:40 a.m. on tuesday. law enforcement, he says, was on the scene within four minutes. but thathour >> during this time that they're makinging inhobrse stopal it immediately, tlshey're also evacuating personnel, students, teachers. there's a lot going on a lot. complex situation. amna: despite multiple questionl timeline details. dr. roy guerrero was at the hospital when many of theernd or everywhere, blood on the floor, kids in the hallway bleeding, am: dr. g, as he's known, hasin

cared for hundreds of uvalde children since they were babies. >> the first thing i thought was like, oh, crap, is this one of my kids? and lo and behold, it was. and not just one, two, or three, this count so far it's five. amna: five kids. that you treated. >> that i've seen since they were newborns. amna: guerrero described the scene that confronted medical staff at the hospital. >> probably the most horrible thing i've ever seen in my life, basically not recognizable, with the majority of his facial featur and head missing at that point. and then you cover that part back up. you can just recognize a little boy below that, you know, with a cartoon shirt, cartoon shoes. and this is a kid that was just at school doing their normal daily thing. so i think that was the hardest part of my day. amna: among his patients, an 11-year-old girl who survived the shooting. >> in a nutshell, this kiddo just said that, you know, she was in a room where r teacher she actually expined how her teacher yelled out, asking for

help and asked her to call 911. and this kid was smart enough to cover herself with blood that she had found on the floor to act like she was deceased, basically. so the shooter would not identify her and shoot at her. amna: this little girl thought to do that? >> she did. she did, you know, 10, 11 years old and can think like that. amna: as the names of the victims were confirmed, dr. g remembered one in particular, amerie jo garza. >> i have known her since she was basically a newborn. this kiddo was yours all this time you saw them grow up, and now they're gone. and we don't understand why. i think it's the finality of that, right. that that you can't change it no matter what, no matt what you do. amna: for the second straight day, people in and around uvalde turned up for one another, lining up here for a blood drive. >> you can't do anything else. you can't give money to the families. maybe you can't bring food, t

the little thing you can do, like donate blood, and we do that. amna: keric hill drove from his home 65 miles away and took the day off work in order to donate. >> y'all cover all this now. but in two weeks, a week, the next event, all the cameras will onllbe bane go ging through the same thing. everybodwill be changed here. there's no way something like this can happen in this kind of area with the way these children have seen things, the way law enforcement, everybody had to clean everything up and it just -- there's no way this isn't going to last. amna: texas gubernatorial candidate beto o'rourke, who's long called for gun control measures, also gave blood, and spoke to reporters afterwards. congressman, these kinds of attacks still seem to happen. is there any sense this time is somehow different in any way? that something will change? >> it is up to us. it's up to all of us. these kids, their parents with whom i've met, didn't choose

this. we, the people of texas though, have a choice. we all know we can change this. we all know we have the power to change this. we all know it's going to take a long time.naam: gwief thtirough the community, hundres streamed into a vigil last night. locals filled the standsth te rafters, spilling onto the dirt floor. a space typically reserved for rodeos, last night was a house of healing. >> i cry a lot. and i cried a lot today and yesterday. i may cry some more here as we speak. you may cry. because our hearts are broken. we are devastated. amna: the prayers and powerful messages belie the deep pain many here are still carrying. roy and dora sotelo brought

their two daughters to the vigil. as the girls' schools went on lockdown during the shooting, little sister leia texted big sister chloe. >> i opened my phone and i went to facebook and i saw the police department posted an active shooter at school. the first thing i did was take some friends and ask if their siblings are okay. and then i texted my sister because she texted me. she was like, i love you. if anything, just remember that. and i texted her like, you're okay. like, you'll be fine. amna: you sent her that message? why? >> because i didn't know what was going to happen. i didn't know if it was going to be my last dayno ot. lost their kids, and it's hard, you know. you want your kids to bury you.. so, it's hard. it's hard. amna: residents here are still

that loss and grief. even as we stand here today, community members continue to show up to bring flowers and memorials for the 19 children and two teachers who were killed. funeral preparations are now underway. and two funeral homes have confirmed they are providing to funerals free of charge. but there is a growing sense of outrage over why more was not thne, and could more haeeveding ting o bno that day to possibly save the lives of those children and teachers. judy: oh amna, it's rclt tha un together, but it is so hard to listen to these families he spoke with. thank you. this latest attack has once again raised questions about how to prevent these kinds of tragedies. and here in washington, a bipartisan group of lawmakers met today to discuss what, if

any, potential solutions could earn the necessary 60 votes in the u.s. senate. carl hulse is the chief washington correspondent for "the new york times." he joins me from capitol hill. welcome back to the newshour. your piece that you wrote this morning was headlined, "why republicans won't budge on guns." and you quoted a comment from north dakota, senator kevin cramer. tell us about that exchange and what he said. rl: senator kramer, i give him credit for being forthright, was engaged in a discussioand said, you know, i don't want to take things off the table, i am going to consider things. and i said, what would happen to you, how would your voters respond if you back in control? he said they will probably throw me out of office. i think that kind of sums up where a lot of republicans are on this issue.

unun terrible, horrific mass killing, pressure on capitol hill to do something about it, talks start about doing something about it, but they don't really lead anywhere. there is a little bit of optimism this evening that despite partisan group could get somewhere, members say things feel different this time, but is rmartoid neel iectionis year them findiny really significant agreement. so we are just going to have to watch it. congress left today, the senate, for about 10 days, and that can take momentum out of these talks too. so, a little bit of hope, but not much optimism if those two things can go together. judy: we have heard in the past a little bit of he after the kinds of incidents, but most of the time it has faded after. i do want to ask you where this opposition comes from, since there are public opinion p largf

regulation, background checks, for example. opposition come from? carl: it isthreis whes d aoen g thing. it is overwhelmingly popular. but these members here, the titate people take their gun rights very seriously, certainly in north dakota, south votes would have to come fro membs worry the backlash will come from those people, almost a single issue voter type of situation, where if coue thehe d and weakened, the nra, by some internal scandals, but it is still a force in republican politics. no

of course a lot of the primaries are already done this year, but that does not change the calculation. a lot of republicans really think that guns, gun rights just have to be unfettered and they are going to act that way. it is hard to see -- as you said, it's going to take 10 votes from republica to break a logjam or a filibuster on gun rights. it is hard to count to 10. judy: just to be clear here, you e saying that even if there were not the nra out there lobbying, and ocourse they are a powerful organization and they give a lot of money, you are saying even without that, because of the grassroot support for gun rights, you believe republican numbers would be what they are? carl: i do. i believe they are responding not just to the nra but from their constituents. they hear from their

constituents, there is a lot of fear in that community that the federal government is out to take their guns. of course that is not correct even with the limited universal background checks that people would like to see put in place, americans have a lot of opportunity to buy guns. but it's just this ideological issue, and they are not moving away from it, even in this setting. however, these talks might produce something. there are some new developments. senator john cornyn, who of course you know from texas, former member of the leadership, he seems to be taking part. it is his home state, people are saying he is someone to look at. it is possible. but chris murphy, snator from cueccoigt, ltider on gun control efforts in congress, said today, we're going to try, we're going to give maybe two weeks, but there is no agreement we are still going to force votes on

the senate floor and get everyone on the record. judy: we actually spoke with senator murphy here last night. what is so interesting is seeing this opposition to any regulation stays so strong, despite these rapidfire, military style weapons that are being used. carl hulse, thank you so much. carl: thank you. judy: the horror of what happened in texas is leaving yet more families, friends, and community members grieving and reeling over the loss of loved ones. it is an experience that many survivors and families know all too well from previous attacks at sandy hook, aurora, parkland, columbine, and too many others to count. john yang talks about that with a survivor of the parkland shooting. john: judy, in february 2018, 17 people, 14 of them students, were killed and 17 others wounded in a shooting at marjory stoneman douglas high school in parkland, florida.

it remains the deadliest high school shooting in u.s. history. survivors, families and friends of the dead, and other parkland residents have dealt with their pain and grief, and many are now activists. aalayah eastmond is one of those survivs. she's on the executive council of team enough, a youth-led movement working to reduce gun violence. she is also a student at trinity college in washington, d.c. thank you so much for joining us. having survived the horror of that high school shooting, i imagine it is very difficult for you to hear about, to lea about the shootings in t past couple of weeks, buffalo and now the shooting in texas. help us understand, what have the last two weeks been like for you? aalayah: honestly, i cannot even remember half of my week because all i have been focusing on is these shootings because they keep happening, back to back. and we have to also knowledge

the everyday gun violence we are seeing in our communities and inner cities as well. so my mind s just been on, go. and it's been filled with trauma and flashbacks relating to my shooting i experienced in 2018 when i was only 16. so it is just a lot of numb feelings, a lot of anger, a lot of disappointment, and honestly a lot of shame, because i think the issue of gun violence is someing we should be ashamed of it is country. john: if you had a message for the people who were in that chie in the school in texas, what would it be, what would you want to tell them? aalayah: honestly, i would just say that i am so sorry that we couldn't prevent this from happening since parkland. parkland should have been the last. sandy hook should have been the last. columbine should have been the last. we keep seeing these shootings happening year after year after

year, and not enough is being done to prevent em. i, honestly, as a fellow survivor, i would apologize because thiss preventable and this should not be happening. especially, especially elementary school children, should not have to deal with being gunned down in their schools. john: what would you tell them to help them prepare for the days, the weeks, the months, the years ahead? aalayah: for me, grief and trauma is different for everyone. for me, it got a little harder for me as i went to college, after high school, and i decided to go to college out of state. so it was hard to be away from family, but i do want to emphasize that it gets a little easier when you know how to function in your new normal. a lot of times for gun violence survivors, especially for my high school, we look at life as before the shooting and then after the shooting. so, acknowledging what life was before and trying to get back into that happiness or that group is -- groove is somewhat

helpful, but it is difficult antivert -- and different for everyone. but i would emphasize being around family and friends and loved ones know the rest of the country is standing with you, we support you, and we're always here to support you in whatever endeavors you have coming forward, or in anything you need support with. john: if history is any guide of the future, the survivors of buffalo, the survivors of uvalde, texas, are going to have weeks like you have just had, of having to hear news reports of these things again and again. is there anything you can say to help them prepare for that? aalayah: yeah. i mean, it is different for everyone. having the power or the tools of social media makes it a lot harder to separate yourself from these tragedies, because we are seeing it consistently every single day on our cell phones, on rtv's. but one thing that i another survivors for my school like to

do is when we see things that are happening and it gets overwhelming, it is ok to put your phone down, it is ok to turn off the tv, it is ok to take a moment to be with your family and your friends. especially when tragedies are happening, it is like a flashback for survivors. it is a moment to remember what you experienced, and that can be hard, especially when it is a normal, random weekend and you hear another mass shooting happened. so, just taking time for yourself is ok. just surrounding yourself with people who love and support you've is the best advice i can give. john: you talked about wanting to apologize for these people that, it happened again, it happened to them. the fact that nothing has really been done, or very little has been done since the incident that you are high school, does that make you angry, does it make you frustrated? are you resigned to nothing happening? are you hopeful that nothing -- hopeful that something will happen?

aalayah: i am disappointed, angry, literally all of the above. especially as a young woman, growing up in this generation where we have to fear for our lives because of gun violence. it does not even matter where you are, where you are located, what you are doing. it is one of those things that can happen to anyone, anywhere, at any time. and it is honestly scary. and i am just so disappointed in this country and leaders of this nation for continuing to turn a blind eye to this issue and not listening to theoung people who are crying for help, who are ying to not have to worry about going to school and being gunned down. or family member is going to the grocery store and being worried about being gunned down any grocery store. or churches, or anywhere. it is honestly a disgrace and the leaders of this nation should be ashamed of themselves and the need to step up and do action now, because this will continue to happen as the years go on. john: thank you very much.

aalayah: thank you. judy: the massacre in uvalde is again driving heated debate about the millions of guns owned by americans, and how some clearly disturbed people can get those weapons and wreak havoc in an instant. william brangham has more on what we're learning about how to interrupt that process. william: that's right, judy. there is a technique known as behavioral threat assessment that tries to do just that, to recognize the warning signs that someone is about to commit a violent act, and find a way to effectively step in and head off disaster. i'm joined now by two people who know a great deal about this work. mark follman is an editor at "mother jones," and author of "trigger points: inside the mission to stop mass shootings in america." and marisa randazzo is the executive director of threat assessment at the security firm, ontic. she used to be chief research psychologist at the u.s. secret service.

thank you both very much for being here. mark, to you first. a lot of your book looks at the research and implementation of these behavioral threat assessments. could you explain what they are, what are they looking for, how does it work? mark: yes. so this is a method that brings together multidisciplinary expertise in mental health, in law enforcement, in education, in other fields, to work coaboratively to evaluate specific individuals who are raising concern that come to the attention of authorities, to try to figure out the level of danger with threatening comments or social media posts or other concerning behavior. and to try to figure out what the root problems are with the individual so as totep in and intervene constructively. essentially, to get the person they help they may need. so many of these people who commit attacks are people spiraling into crisis, suffering

from rage and despair and developing violent ideas, then planning to carry them out. so that presents opportunity to intervene before it is too late. william: marisa, you have been helping develop and implement some of these types of actresses. -- practices. it sounds like this research punctures some of the myths we have about these attacks, that someone just snaps in an instant and es on one of these rampages. but also as there is a sort of recognizable pathway leading up to these events, that we can intervene in. can you explain a little more about that? marisa: research that i have been part of and others at the secret service and the fbi and elsewhere, for the past several decades, has actually shown that these types of shootings are thought out in advance, planned out in advance, that the planning behavior is observable to other people around them, and most importantly, that the would-be shooter tells other

people before hand about the violence that they are planning to commit. so there is information out there, which from a behavioral threat assessment standpoint, means we havenppnio veromeone on that pathway to violence and to move them off that pathway to violence before they can do harm. william: so mark, picking up from that, let's say school officials, law enforcement, it is doing these assessments,ev dntoerparee identifications that someone is in trouble. what happens then? mark: what a team will do is develop a plan to then manage the person of concern and to try and help them. and get them onto a better path. this is a process that takes place over time for it i was able to go inside a number of these cases over many months in a community in oregon. school district there has a r eal robust version of this

model. often what you see is by extending a troubled student help with counseling, with individual education support, with working closely with the family whenever possible, these troubled people can be helped and moved onto a different path and do better. there e successful cases like this that are happening quite a bit around the country. the public doesn't hear about them because the result is good. there is not a violent outcome, and so it is good we don't hear about them. william: we so rarely hear good news about these things, it is good to know those things are happening. marisa randazzo, i wonder if you could talk more about what you were mentioning before, which is, the things we know are warning signs -- i know there are a lot of parents, a lot of family members out there who are thinking, is what i am seeing in this young person in my life just natural teen angst, or is this something more problematic? can you take off some of the things -- tick off some of the

things that really do stand out as warning signs of trouble? marisa: one of the things that is really important is students will likely be the ones who here long before an adult notices any concern. students are likely to be the ones who have heard about these ideas, these plans of violence. maybe someone is starting to joke about it, talk about researching previous attacks. so, any students, any peer who sees something directly, sees it on tiktok, youtube, instagram, wherever it may be, if they hear anyone mentioning engaging in, thinking about, planning for some type of school shooting, or some type of violence, it is really important to bring that information forward. so that is a big piece that our students can help in terms of safety. the other piece is, one thing we often see and we miss is that, especially for boys and young men, depression looks quite different than what we see from

the hollywood script. so, depression in boys and men often comes across as active anger, rage, an attraction to extremist ideology, attraction to hate. and we might just dismiss that as, boys will be boys, or it's just a phase. it actually might be a symptom of underlying clinical depression. so parent who sees that in their own child, a teacher who sees that, it is important to get this to your threat assessment team, or get ts information to someone who is in a position to take a look at this clinically. even if it is a pediatrician. and say, hey, i am concerned about this, could this be a sign of underlying clinical depression? william: mark follman, your book has several examples of several --caucyoceu ssgifuvel u inta ere example where people saw a particular case, a young person,

what they saw and how they acted? mark: sure. one story i tell on the book is the case of a high school junior who i call brandon. this is in the salem kaiser district in oregon. and he made a series of threatening comments, or what could have possibly been threatening comments overheard by peers. he talked about bringing a gun to will and shooting up the school on friday. one student who overheard was not sure he was joking. this is a pattern we see in a lot of cases with school threats and shootings. with the buffalo shooter and the shooter at oxford high school in michigan, there wereboutjuing. t ts afanin important signal to 18, especially with -- to a teen, especially with a series of them over time. they figured out many other things were concerning. he was deteriorating personally, he was failing out of classes, he quit a drama club he was very engaged in. taken together, these were a

picture of a student in crisis. and coupled with threatening comments that he was making, they took a serious look at move to intervene quickly. they first had to determine, did he have access to the gun he was threatening to bring to school? it turned out the answer was no, but then the question is, how do you manage this over the longer-term? the team made a plan for that and worked with teachers they can work with more closely. often there is a lack of connection with at risk use -- at risk youth who are starting to think about violence of this nature. and over eight period -- he was no longer thinking about violence and planning violence and went on to graduate. william: that is what we need to hear more of. marisa randazzo, you touched on this before, which is, in the case mark is talking about, and in all these other cases we now

know unfortunately by name, these aryoung men were largely meeting these mass shootings. do we know why? what is the connection between being a young male in america and being the overwhelming preponderance of mass shooters? marisa: one big piece that is often not talk about is the vast majority of these shooters are at a point of being despondent or even suicidal when they carry out these attacks. some of them have planned to kill themselves at the end of the attack they were engaging in. a lot of the tools that we have available to us that we know helps someone who is feeling suicidal are actually quite appropriate for managing cases like this, where their thought is about taking other lives before taking their own. that is a big piece of what is motivating it. there is often these underlying problems that they now feel

overwhelmed -- they overwhelm their ability to solve them and cope, and they may start to look at suicide as a solution, they start to research it and discover others who have engaged in a homicide, suicide situation, particularly these mass school shootings. so they start to look at it as a viable option. when we canncover someone who is starting to think along those lines, figure out what that underlying problem is, why are they feeling overwhelmed and despondent and like they have no options left, they don't want to live anymore. that is where we can get in, find solutions, connect them to support and care, and get them off the pathway to violence and keep them off the pathway to violence. william: so important to know this work exists and it has had some successes. marisa randazzo, mark follman, thank you both very much for joining us. marisa: thank you. mark: thank you.

judy: in the day's other news, russia insisted that ukrai, understand quote, "the real situation" and accept moscow's demands. ose include ceding swaths of nd. in eastern ukraine, russian fire pounded dozens of towns, leaving debris and smashed homes. ukrainian officials conceded their troops face an extremely difficult time. >> as of today, the aggressor conducts intensified fire along the whole line of contact and the positions of our forces in the donetsk operational region. the situation is difficult and there are signs of escalation. the enemy has used all resources to capture our territory and surround our forces. judy: separately, russia's president putin suggested his naval blockade of ukraine's ports could ease if western sanctions are lifted. the blockade has largely stopped

ukraine's grain exports. the biden administration called today for the bloc of nations confronting russian aggression to join in challenging china. secretary of state antony blinken criticized beijing's aggressive moves abroad and increased repression at home. he said china poses an even greater danger to global order than russia does. >> while our policy has not changed, what has changed is beijing's growing coercion, like trying to cut off taiwan's relations with countries around the world and blocking it from participating in internation organizations. and beijing has engaged in increasingly provocative rhetoric and activity. judy: at the same time, blinken said the u.s. is ready to work with china on climate change and other issues. meanwhile, china's top diplomat began a tour of eight pacific island nations. it came amid growing concerns over beijing's spreading military and financial influence in the region. the chinese foreign minister led

a large delegation to their first stop, the solomon islands. the two nations have signed a sweeping new security pact. the oust mriedteinmer isof pakistan, imran khan, called off a mass sit-in outside parliament today. thousands of protesters had clashed with police in islamabad, calling for the new government to resign. khan demanded new elections, or warned he'd be back with three million supporters. >> i am giving the government six days to announce a new election date, announce election dates in the month of june, dissolve assemblies. if you do not, then i will come back to islamabad with all of my men. judy: the current prime minister signaled is open to talking with khan, but he said any decision about elections has to be made by the parliament. back in th country, a state appeals court in new york ruled civil probe of his financialmust

dealings. his son donald junior and daughter ivanka are included in the order, first issued by a lower court. mr. trump could still appeal the state's highest court. he also still faces a parallel criminal investigation. new census estimates that eight ofhe 10 largest american cities lost population in the first year of the pandemic. new york dropped by more than 300,000 people. los angeles and chicago also made the list. san francisco lost more than 6% of its pre-pandemic population, the largest rate of decline. on wall street, strong earnings reports from retailers gave stocks a boost. the dow jones industrial average gained 517 points, more than 1.5%, to close at 32,637. the nasdaq rose 306, more than 2.5%. the s&p 500 added 79, 2%.

and after ray liotta, best known for his roles in goodfellas and field of dreams, has died. his publicist says he passed away in his sleep overnight in the dominican republic as he was filming a movie. ray liotta was 67 years old. still to come, why north korea conducted missile chests -- missile tests shortly after president biden's trip to asia. and the first black winner of the pritzker prize for architecture explains his innovative work. >> this is "pbs newshour" west from weta studios in washington and in the west from the walter cronkite school of journalism at arizona state university. judy: this afternoon the u.s. confirmed north korea tested intercontinental listed missile earlier this week. that announcement was made in the security council where china and russia vetoed a resolution that would have imposed new

sanctions on north korea. all of this coincides with the e story.s airtedm sstifdriitn hh tb>> the provisional agenda for this meeting is nonproliferation. nick: in new york today, a failed attempt to further isolate north korea. >> we cannot let this become the new norm. we cant tolerate such dangerous and threatening behavior. ni: the security council ejected a u.s.-let resolution to sanction north korea and deliver humanitarian aid because of russian and chinese vetoes. through a translator, the chinese ambassador said sanctions would honor the people of north korea, whose official acronym is dprk. >> neither right nor humane. nick: the vote w response to north korea testing three missiles on tuesday including what the u.s. said was the sixth launched just this year.

their response was not only diplomatic. hours after the north korean test, south korea and the u.s. launched a range missiles and displayed dozens of american-made fighter jets. already this year the u.s. says north korea has conducted 23 ballistic missile launches and is trying to build an arsenal that can survive a u.s. attack. >> we have seen hypersonic missiles, we have seen submarine-launched missiles. so really, making and creating missiles that are harder to detect. nick: senior fellow at the wilson center and a former journalist based in pyongyang says the test timing is no mistake. >> we committed to strengthening our close engagement. nick: immediately after president biden's first asia trip and a synchronized message from the south korean president to north korea. >> president biden and i shared serious concerns and agree on the need to prioritize them over any other issue. >> it is hard not to see this as

a kind of rebuke or response to that show of strength. interesting it was not timed to take place during the visit, but just after. nick: what is the significance of waiting, i suppose, until biden left? >> perhaps there is a little bit of a signal there that he wants to raise tension. but i think he does eventually want to get back to negotiations. ck: four ars after north korea's less nuclear test, u.s. officials are worrying they are excavating tunnels at their nuclear testing site to prepare another test. >> the developments and advancements every test makes in terms of nuclear devices, they get more and more powerful each time. each of these tests has been closer to perfecting this technology, refining this technology. nick: but north korea now faces a different test in the military and new mobilization. last week medics help to treat

what they called fevers. health workers visit residents suspected to be sick. the equivalent of dr. fauci gives daily updates. >> we are aggressively broadcasting informative programs as residents want to know about this epidemic disease clinical course and medicine treatment. nick: those programs tell citizens to make gargles with salt, drink herbal tea, and take painkillers. and they promote homemade cures. >> i disinfected the room with alcohol, and circulated air. i think it can be treated like a regular cold. john: cove it is now openly discussed because kim jong-un himself declared a national emergency. north korean officials say more than 2.5 million, 10% of the population, got sick. >> it is a major outbreak and it is nationwide, in every province. nick: a neurosurgeon who has been training north korean doctors for more than a decade since the country's

infrastructure is ill-prepared. >> i am concerned about the capacity of the north korean health system to absorb the surge of patients. there are just a handful of ventilators. i worry about oxygen, then basic medical needs like drugs, iv fluids. nick: north korea had shut down its borders and until recently, claimed zero covid cases. but the country partially reopened this past january and increased trade with china. this week, officials said cases were dropping, but their population is vulnerable. 40% are under nourished and nobody is known to be vaccinated. >> you have the virus ripping through the country and a population unprepared, in two ways. one if you have a vulnerable population that is under nourished. on top of that you have zero vaccination and no inherent immunity. nick: so far north korea has rejected all offers of vaccines, including from the u.s. and u.n.

but admitting a crisis might mean north korea is open to getting health. >> to cement his legacy, it would be a different focus for kim jong-un, and he would start looking at foreign policy. i think that also means looking for a way to signal to the outside world that he is ready to start engaging, that he is ready to start reaching out. nick: what north korea is perhaps not ready for, fighting a virus it is only now admitted it cannot control. for the pbs newshour, i am nick schifrin. judy: the biggest international prize in architecture, the pritzker prize, will be awarded tomorrow in london. it's going to an architect known for his work on buildings that address social needs, particularly in african countries. this year's prize also makes history, as francis kere becomes

the first african and the first black architect to earn the honor. jeffrey brown has the story for our arts and culture series, canvas. jeffrey: a primary school built in 2001. the first in the village of gando, in the west african nation of burkina faso. its very existence, plus its use of local materials, natural light, and ventilation, have made it a game-changer for its community, for the field of architecture, and for its designer, diebedo francis kere, who'd had to leave his home here a nearby town. >> going to school is still a big, big dream for millions of young people in africa. this is still a big dream. and so, i was very, very lucky. and i felt privileged to be able to attend school education. what do you do if you are privileged like i am to be one of the very first from my community to attend school

education? so i went back trying to build a school for the other kids. so that was how i started my care. jeffrey: that career, after a scholarship later allowed kere to study in germany, where he continues to work, has now won him the pritzker prize, architecture's highest honor. but he's never forgotten the experience of sitting in dark, stifling classrooms as a child. >> you had very tiny little openings and you had no light inside the classroom, while outside you had the bright sun. so i wanted to create the school in my village to allow other kids to stay in the villagand be able to attend education. education is so important for human development. but i wanted to have better classrooms. i wanted to have well-ventilated classrooms. i wanted to have a bright person. i wanted people to feel happy going to school. jeffrey: last ar, a "new york times" survey named the school he designed in gando as one of the 25 most significt works of

postwar architecture. and kere, now 56, has continued to define and refine an architecture of social purpose -- schools, housing, healthcare centers, and more. mostly in africa, always working with limited resources, and using simple materials such as wood and clay. kere often works closely with community members, at times including them in the building, and even helping raise funds for projects through a foundation he first created to help build the scol in gando. this doesn't sound like the normal activities for an architect. >> yes. yeah, this is right. it wasn't that easy. it was not the normal y. i needed to create this structure in order to raise the needed money to be able to build the school. and we succeeded, honestly. i think it was good. you know, a greaexperience. for me, it was the best thing that i could do. jeffrey: why has it been so important to involve the community, even having them help

build some of these buildings? >> it's really important. it's about how do you transfer knowledge. if you build a school and you have the community be involved, there are two things that are happening. first, you are getting the community to really become proud. the common sense. it is we. it is our school. and, you know, they wi protect it. the second thing, most important, is knowledge. you are transferring knowledge. and then you're making your community even stronger. at the end of the day, i am the one that gained a lot from that. i have a happy community that has the school and i'm very happ and i am getting even to talk to you, to talk to you, jeffrey. can you imagine? jeffrey: kere's firm designed the serpentine pavilion in london in 2017. and he's shown a whimsical side in so-far limited work in the u.s. -- colorful towers for a 2019 itallation at the

coachella music festival. a structure called xylem at the tippet rise art center in fishtail, montana. among his recent or ongoing projects, the benin national parliamentnow under construction. the goethe institute in dakar, senegal. a community playground soon to open in kampala, uganda. and, in the design stage in germany, a bridge in mannheim and a kindergarten in munich. at the heart of every project, he says, are the people he's building for, especially in his home region. >> i realize, wow, i have not just only created the structure, but i am changing the game, how people see things. you know? people in my place, they love the west. you don't know that. they love the west, they love your culture, and they want to have it. but often we don't have educated people to get our people to bnefit from all these achievements in science, you

know, in design, in economic innovation. and i did, with architecture, i did this for my people. jeffrey: how much does your work -- how much does that translate to work that you do in europe, in the u.s., in work that you will do? >> my work is transporting optimism. it is looking how we can learn from past and to create something that is refreshing, by applying materials that are not causing a heavy burden to the environment. so these issues are not just for the poor, the poor community. it is worldwide. jeffrey: another way in which this prize is important, kere is the first african and first black architect to win the pritzker in its 44 year history. >> it's just history and i am gert of it. a b prisole

, taif, it can inspire others. but about the field of architecture, there is something we have to know. studying architecture is very expensive, very expensive. and the access to any kind of education in africa, where you have most black people living, is also not easy. jeffrey: and then there is the cost of building itself. but kere believes that an increased focus onhe kind of work he does can help change the larger field of architecture. >> in the moment, there are more elements that can contribute to architecture than in the past. the social component is being seen as something that is important. climate issues is important. and so i am very happy that my work has become where this was needed. but i wish that the world will create more schools in africa so that we see in the near future more inspiring examples from africa. and i hope many of them will win pritzker. for sure, they will. jeffrey: alright, diebedo francis kere, congratulations

again, and thank you very much. >> thank you. thank you very much, and i hope to see you soon. thank you. judy: i love that he says he wants his work to project optimism. and with that, that's the "newshour" for tonight. i'm judy woodruff. join us online and again here tomorrow evening. for all of us at the "pbs newshour," thank you, please stay safe, and we'll see you soon. >> major funding for the "pbs newshour" has been provided by. >> for 25 years, consumer cellular has been offering no-contract wireless plans designed to help people do more of what they like. our u.s.-based customer service team can help find a plan that fits you. to learn more, visit consumercellular.tv. >> the ford foundation, working with visionaries on thfront lines of social change worlide. and with the ongoing support of
