but how do you, with kids a little older, how do you explain to them what's going on? >> it's important to use simple, honest language. we have a tendency to want to shield our children from the scary things going on in the world. but the reality is we're all living through this. but having a plan ahead of time, just what are you going to say to your children. daddy is sick right now and he can't be in the same room as you. or we have to wear masks right now because we're sick. >> the episode will be available on cnn plus on wednesday. i hope uk check it out. the news continues. let's hand it over to laura coates and jim sciutto in coates and jim sciutto in ukraine. -- captions by vitac -- www.vitac.com anderson, thank you. this is cnn tonight. i'm jim sciutto, along with laura coates. there is big news this evening. the state department is considering labelling russia a state sponsor of terrorism, a

designation reserved only for north korea, iran, cuba, and syria until now. it would be a significant development and a sea change in relations between two superpowers if that were to happen. we will take that to a key administration official in just a moment. meanwhile, a new phase of this ruthless invasion has begun. president volodymyr zelenskyy announced to his nation tonight that russian forces have started the long-expected and expanded battle for donbas in the east of this country. he told cnn friday what happens in donbas could then set the course for the rest of the war. russia has completed regrouping troops for this new major offensive, according to ukrainian officials. and although the fiercest battles are in the east and south, lviv here in the west, got hit by at least four different missile strikes today. you can see some video of one of those missiles as they streaked across the sky. watch how fast it goes. we'll have more in just a

moment. laura also has breaking developments this hour on the uptick in violence back home. >> yes, jim, ten mass shootings here in the u.s. just this weekend, and it was a holy weekend at that for many. gunfire at least at two house parties, one at a mall, and elsewhere have left eight dead and dozens injured. and this on the heels of that horrific subway mass shooting in new york city just last week. so, in many congress keep saying we're going to do something about the gun violence epidemic. but the question really is, when will something be done about it? we'll put that question directly to a member of congress. that's ahead. there's also big breaking news tonight on the federal mask mandate for travellers. a florida judge striking down the administration's masking rule for planes and other public transportation. this is less than a week after the cdc extended it through the 3rd of may. so, what does all this mean? and this comes amid a new uptick in covid cases. the question is will the

administration really appeal? but first back to jim with what he personally witnessed in the city of lviv just today. it's unbelievable what you're seeing right now. >> listen, laura, you know, terror, it has been part of the russian battle plan since the start of this invasion. and russia brought terror to lviv today. multiple times those air raid sirens went off. and in the morning those sirens were followed by the booms, the explosions of missile strikes. >> reporter: a missile streaks across the sky over lviv in western ukraine. russian forces launching cruise missiles on multiple targets here. an auto repair shop, just as it was getting ready the open, with several employees on site. transformed into an inferno. also hit, what the regional military governor described as three military warehouses. this is the scene of one of the

missile strikes this morning. uk you can see the emergency responders back here. but as we arrived, another air raid signal went off. the soldiers are concerned this will be a secondary strike on the same target. ukrainian soldiers ordered us behind a concrete barricade. nervous about us filming any soldiers or military facilities, one member of the territorial defense forces cocked his rifle, as he shouted at us to move back. as other sirens warned of more missiles on the way, we took shelter in a closed restaurant. after several hours, finally the all clear signal. and this is what was left behind, two ambulances outside one of the damaged military warehouses guarded by ukrainian soldiers, damaged cars, fallen trees, a section of railroad track thrown dozens of yards by

the force of the blast. the auto repair shop destroyed. the owner told cnn several were killed here. in all, the victims numbered at least seven dead, 11 wounded, including a child. one toll in one city among many suffering through war here. >> you know, jim, for many people, we know, of course, about the millions of people who have fled ukraine into neighboring countries. but for a lot of people, at least 200,000 people, they were internally displaced and actually going to lviv where it seemed to be a safer part of the country. i mean, where else can families go now if that's no longer the case? look at what's happening there now. >> no question. you know, lviv has been something of a lifeboat throughout all this, a place of refuge for people either transitting through here on their way to poland and elsewhere in eastern europe or just to stay here and hoping to wait out the war to some degree. but of course today -- and it's happened before, but it's been some time. but today the war came here again. so, the question is, do they

then move out of the country, as many millions have done? do they look for other cities? the trouble is showing that russia is showing it can strike anywhere in this country. >> and i wonder what would it mean now if the u.s. were to label russia that state sponsor of terrorism, as you mentioned? >> it's in effect a new round, a new category of sanctions. it would prevent russia from buying a whole host of products and dealing in a whole host of trade, both for military and commercial products. and then as a second step, it would then penalize other countries that would deal with russia in those same categories. the significance, steph, think of the club russia would be joining there, iran, north korea, and syria. >> and i wonder, when you think about what's going on, there's been a lot that's happened since you visited the first time in lviv. you've been back now. you were back in ukraine. what's it like now? how has it changed? is it fundamentally different?

do you feel a sense that there's a lot that's changed since the last time you were there? >> i'll tell you, we've been here -- goodness -- 36 hours maybe on this trip and have had four air raid sirens. and one of those followed by multiple missile strikes. it just -- it's a remind thaer there really is no safe place in this country. and we're seeing, you know, as this broadens the impact of the u.s. possibly designating another superpower a state sponsor of terrorism, that's something i discussed with a member of the biden administration just a short time ago. i spoke with matt miller, the special adviser to the u.s. national security council. matt, state sponsor of terrorism. is the administration close to declaring russia a state sponsor of terrorism? how long before the president makes a decision? >> jim, as you know, there's a formal process that has to be undertaken by the state

department to make that kind of determination. i will say about that, when you look at what flows, there's a number of sanctions and economic measures, many of which we have already imposed. if you look at the packages of sanctions we've imposed on russia, they're extremely serious and have brought enormous economic devastation to the russian economy. so, that is a tool that remains in our tool box, and of course we continue to look at all available measures. if you look at the practical implications of what that designation would be, we have pretty much put into place all of those measures already. >> i was in geneva -- this was just last summer, as you know, when putin and biden met. and the discussion there was of strategic stability between russia and the u.s. here we are less than a year later, and the u.s. now considering declaring russia a terror sponsor. did the biden administration misread putin? >> not at all. we always made clear that we wanted strategic stability.

we wanted to have a stable relationship with russia. we wanted a russia that would contribute to european security. but we were always ready, if russia chose another path. even leading up to the final days before russia's invasion of ukraine, we made clear that we were open to diplomatic negotiations. but that wasn't meaning we weren't also clear eyed about the threat russia posed. we've been clear eyed about that since the beginning of the administration. even before the invasion, this administration was committing hundreds of millions of dollars of security assistance to ukraine. and of course in the days since the invasion, we've continued to flow billions of dollars in security assistance to ukraine to help it defend itself against russia, while imposing those serious economic measures that i spoke of a minute ago. >> as you know, the uk prime minister has visited ukraine, the leaders of a number of nato allies have visited ukraine. when will the u.s. send a senior official to visit here? >> well, that's not something that we would discuss publicly for security reasons. if we do send a senior high-level representative to

ukraine, that's something that we would not announce in advance. but we do continue to be in close contact with the ukrainian government at very senior levels. the president talks regularly with president zelenskyy. secretary blinken talks with his counterpart. and the national security adviser at the white house, jake sullivan, talks nearly every day to the senior adviser to president zelenskyy. while we are not on the ground in ukraine right now, we are in close daily contact with our counterparts in the ukrainian government. >> well, those other leaders face the same security risks. and by the way, other diplomatic teams have been returning to ukraine. france among them. and u.s. diplomats still not here. why is the u.s. behind on this? why isn't it leading the way? >> look, every country has to make its own security assessments. i will say we continue to assess the situation on the ground in ukraine. obviously we want to be back in ukraine. we want to have a diplomatic presence there. we didn't want to leave in the first place. but we have to put first and

foremost the safety and security of american diplomats and american personnel who would be there on the ground. so, we will continue to assess the situation. and when it's safe to return to ukraine, we will do so. >> today, as the offensive, the russian offensive intensifies in the east, the pentagon explained their plan to, quote, train the trainers. this is in terms of teaching ukrainians to use these american h howitzers the administration is providing in this latest traunch of weapons. given that offensive is already underway, i just wonder why didn't that training begin earlier? why weren't these weapons on the ground earlier? >> jim, as you know, we did have american personnel in ukraine training the ukrainian military before this invasion. we've spent months, years, training the ukrainian military to get ready for acts of russian aggression and help them defend the russian aggression that's been happening since 2014.

so, the training that's going on with the howitzers is not a new act for the united states. now, look, we do flow new capabilities in to the ukrainians all the time. sochl those capabilities require new sets of training. we do that as quickly as we can. but i will say the speed and pace we're getting this assistance into ukraine is really unprecedented. just since russia's invasion of ukraine, we have committed another -- more than $2 billion of security assistance, 50 million rounds of ammunition. we announced last week, we'll provide 40,000 artillery rounds. so, look, we are always looking to do this as quickly as we possibly can, but i will say the amount of security systems that we've gotten into this country in a short period of time, i really do think has been an accomplishment for our colleagues over at the pentagon. >> as we witness here and the world witnesses war crimes, evidence of war crimes by russia from bucha to mariupol and beyond, the phrase "diplomatic

off-ramp" is one i hear less often from administration officials. do you see putin as being negotiable at this point, someone uk negotiate with, that there is a path out of this where this is not settled on the battlefield? his positions have become more, not less, maximalist in many ways. >> yeah, look, jim, obviously it takes two sides to have a negotiation. ukrainians have said they're willing to sit down in good faith and negotiate. and the russians have said the same, but it's been clear when those negotiations have actually taken place that they're not starting from a place of good faith. and at the same time, they claim to want to have negotiations. they continue to launch new attacks. we're seeing them launch new attacks in the east even today. we don't believe the russians are serious about negotiations now. what can we do as the united states? two things. one, we can continue to flow the security systems in to the ukrainians so they can put pressure on the ukrainians in the battlefield. two, we can continue to ramp up

the economic consequences on russia if we use this war. first on the battlefield and eventually at the negotiation table if the russians ever do get serious about negotiations. >> matt miller at the white house, thanks so much for joining us tonight. >> thank you, jim. russian forces redeployed to donbas after failing to capture the capital kyiv. and now we are learning where thousands of russian soldiers may have been based at that time. we'll see what ukrainian forces found there coming up. h. raise the jar to a all five layers. raise the jar to the best gelato... you've ever tasted. talenti. raise the jar.

a senior u.s. defense official tells us there are telltale signs that russia is learning from its failures in northern ukraine and applying those lessons, as it refocuses on its new offensive in the east and the south.

much of that, it seems, is tactical. heavy artillery, aviation support, and nearly a dozen additional battalion groups have been moved into the area. but will that be enough to change the course of this war? phil black joins me tonight from kyiv. phil, you got an exclusive look at a russian military camp outside town that really spoke to some of the challenges they faced during that attempted assault on the capital. what did you learn there? >> well, jim, this was a secret, a hidden camp, that at one point was a base for thousands of invading soldiers, soldiers that also encountered local members of the population. and they talk about the brutality they experienced in those encampments. it gives powerful insight into how they lived and how they behaved once that effort to take the capital effectively stalled. a warning, this report has some disturbing images.

>> reporter: the sign is a warning, beware, mines. the forest serves as protection too. a natural screen, concealing a vast secret. here among the trees, about an hour's drive north of kyiv, are the remains of a sprawling russian military camp. we're showed around by ukrainian special forces. this soldier says the positions were held by russian marines. we see a sprawling network of underground fighting positions, command posts, sleeping areas, and ammunition storage. while everywhere there is evidence of how the russians lived. and that evidence suggests their existence here was neither disciplined, nor comfortable. it is so quiet here now, just bird noise and a light breeze. recently there were 6,000

russian soldiers bedded down through these woods in a camp that is so large you can't see where it begins and where it ends. living here would have been hard. it was through the coldest of the winter days, four weeks stopped here short of kyiv, after they failed to take the capital quickly. the silence is broken by efforts to deal with some unidentified ordnance. this camp is damning proof of russia's failures on this front, poor preparation, desperately wrong assumptions about the numbers and resources needed to conquer kyiv. what lessons do you take from all of this that will apply to the coming battle for donbas in the east? he says, we see the bomb unit forces that invaded this area, and we understand that will be two to three times greater in the donbas. this force wasn't confined to

the forest. its commander officers lived in the nearby village. here civilians tell disturbing familiar story. a local mechanic says he was detained and interrogated for almost 24 hours. he says he was beaten, blind folded, tied up, and subjected to mock executions. he says he's never known fear like it and constantly thought those were his last moments on earth. local priest describes dealing with the aftermath of even greater cruelty. he says, he found five mentor chured and killed in the garden, two more in the forest. and the russians brought him two dead women and told him to bury them. other russians in this area camped out in fields with their artillery pieces, installed what comforts they could, a mattress, alcohol, the works of shakespeare. rockets flew through the sky

toward hostomel, and when they hit the earth, it was often civilians who felt their power. this is the result. so many people -- >> they were hurting in there. >> reporter: in hostomel, this resident shows the aftermath of a russian rocket strike. >> this is the epicenter of the explosion. >> reporter: and where some of its victims were temporarily buried. >> i feel only hate. >> reporter: only hate? >> yes. we can't forgive it, maybe for life. >> reporter: for now, the enemies in the forests, fields, and villages have left this part of ukraine. the fruits of their brief stay, the pain, trauma, and loathing remain. jim, what we saw showed that the force and fire power committed by russia to the battle of kyiv was ultimately insufficient in terms of numbers and quality. and the ukrainian military also very much believes that russia has learned from those mistakes

and is determined not to repeat them in the battle for the east, jim. >> insufficient but brutal. i'm struck by that image there. the names on those crosses recorded just in pen on plastic lids. gosh, the war, just so ruthless. phil black in kyiv. thanks so much for a fantastic story. more here in ukraine later this hour. but coming up as well, the cdc's mask mandate for travellers is no longer in effect because a federal judge just struck it down. will that decision stick? talks to a former biden administration former covid response coordinator. that's coming up. um, she's eating the rocket. ♪ lunchables! built to be eaten.

bringing it back to jim on the ground in lviv in just a bit. but first, something you haven't seen in a while, bear faces at the airport and on the train and on the bus. tonight it is legal to go maskless on public transportation, this after a federal judge has struck down the biden administration's travel mask mandate. but you might want to keep the mask handy for at least two reasons. one, the ruling still has to be reviewed. and by the way, number two, not every agency and company is on board with going mask optional at this point in time. the question is what now. joining me tonight, former

senior adviser of the biden administration on covid response, andy, it's good to see you. what a night this is. i want to read a portion of this judge's ruling because she had a lot to say in deciding not to have this mask mandate. she said, wearing a mask cleans nothing. at most it traps virus drop letts, but it neither sanitizing the person wearing the mask nor sanitizing the conveyance. you say this might be more of a political decision at play here than one that's based obviously perhaps in the science. what do you think about this decision? >> well, look, a wyoming freedom loving organization, so to speak, found a judge in florida who, i believe, is 34 years old, was appointed after president trump lost the election, a former clerk to judge thomas, who -- i think who the american bar association said wasn't qualified for the court, and who is now stretching her lot beyond

what's legally allowed, which is wrong. to even further sbinterpreting e kinds of examples that are meant to stand based on this law. it's a bad ruling. i don't think it's just in the law. but it's also very tricky for the biden administration to challenge it because at this stage, it's not precedential. and the biden administration will need the power and the cdc will need to maintain the power to impose a mandate if the situation gets worse. so, that's going to be a tough decision for the biden administration to make. >> now, of course, the judge, part of the logic that she put forth in the ruling, was that there was not the adequate notice and comment period required when you put out a rule. and the other, to your point, there was no logical justification given to extend it the extra two weeks. probably what they talked about is, you know, you of course used

to be part of the administration's covid response team. so, i think you have the inside track in hearing what is thought of. what was behind the decision, do you think, to try to extend it several more weeks? i think it was in part the -- you know, the variant of the omicron variant and the -- and also thinking about the hospital capacity rates. was that part of the logic? >> that's exactly the logic. you know, i think that by may 3rd, which is the date this was set to expire, we will have enough data on this potential ba.2 wave. this is the latest omicron version. to really know whether or not what it's going to amount to. and that time is very useful to the cdc, who made the decision based upon data and science and wants to do it with great care. you know, the airlines, which i think have been out saying publicly how much they care about our safety and our health and so forth, didn't wait very long, didn't wait but minutes to say that they were going to not allow -- they're not requiring

masks on most of their major flights. so, it would be nice for the public to feel like somebody's watching the data and making these decisions and cares about public health. and it didn't seem like that consideration was there. >> you know, andy, that point, we have some footage. as you said, the tsa has now confirmed it's not going to enforce the mask mandate and there were people on planes cheering when the announcement was made. i'm going to play this for you. take a listen. >> southwest airlines during this whole -- >> yea! no more masks! woo! >> masks now optional for employees, customers -- [ cheers and applause ] >> now, of course, not the biggest of cheers but obviously this is me going to travel and thinking about it. you shake your head a little bit at this notion, thinking about it, there are some consequences

to this. i would note that united airlines and alaska airline have dropped their mask mandates. do you think every other airline is going to follow suit? and mrl importantly, what's the consequence if this happens? we've heard a lot about the air filtration system on airplanes. and of course people take issue with being able to go to restaurants in most places, madison square garden and beyond, but not on airplanes. is there a real risk in terms of having the mask mandate lifted without having the research you talked about earlier? >> this is kind of a victory for mob rule. so, all the major airlines are going to drop the mandate and maybe one that doesn't. but so far almost all have decided that they will. and part of the reason is because this has been a huge burden on flight attendants who have had to enforce what have been a very small number of very loud and uncivil folks who have basically said, you know, i dare you to enforce this mask mandate.

it's not a comfortable position for the flight attendants to be in. so, the small number of people -- and i'm sure we would all love the pandemic to be over. but to say that it's over just because we no longer have to wear masks, don't interpret that as to say this is over. so, my advice -- and i'm going to be flying tomorrow -- is i will wear a kn94 mask. i will wear a well-fitting kn94 mask. and if other people aren't wearing their masks, combination of my mask and filtration will hopefully do the job to keep me safe. >> so, wait, so andy, excuse me, so should the administration appeal the decision then. obviously it's politically tense. it's very dynamic. should they appeal the decision? >> i think that's the consideration they're making this evening. i think they're considering it. i think my advice, what's most important for them is to

preserve the right to reinstate a mandate if we get into another wave in the fall or winter that's really bad. and so the challenges, if they do appeal and lose, if they find another judge like this one, then they will not be able -- they will lose the lever entirely. so, if they can find a way to appeal, to preserve the right -- i think what we need to do is do everything we can to preserve the right of the cdc to make this judgment. i would rather have the cdc and not a 33-year-old judge or an airline ceo making this decision. >> andy slavitt, thank you so much. you know, coming up, the life and death battle over another epidemic. a new wave of mass shootings in america. and a member of congress and former prosecutor believes it's time for law enforcement to rethink its approach. he'll tell us how up next.

144 and climbing. 144 is the number of mass shootings the u.s. has seen just

since this year began. i remind you it's only april. let that sink in for a second. that means we've seen at least 144 instances in which four or more people were shot, and that does not include the shooter. ten of these mass shootings just happened over this past holiday weekend, leaving eight dead and dozens more injured. it's all tragic. but let's zero in on one from yesterday alone. a house party in an airbnb rental in pittsburgh, where two 17-year-old boys were killed. 90 shots were fired in a crowd of 200 people, and many of them were children. please merit there might be multiple shooters, and they are still right now on the loose. i want to bring in democratic congressman conor lamb who covers much of the pittsburgh area. he's also a u.s. senate candidate. congressman lamb, it's unthinkable to think of the

numbers we've seen over the weekend alone and what's taking place. you have tweeted out, you've talked about the issues and what needs to take place. you said that congress needs to do something. talk to me about why the something has not yielded actual results. >> it's one of the most mind blowing things i've seen since my time in congress. i don't see how anyone could object to the idea of controlling the flow of illegal firearms. you know, and we don't know for sure yet in this case, but i am willing to bet based on my experience, and i know you come from that world too, there's a pretty good chance these firearms were being possessed and fired illegally, as they are in most violent crimes. we should be dealing with that from the federal level. that's what the atf is there for. we should be imposing better background check rules, closing loopholes, and just giving the atf the resources they need to intervene and stop firearm traffickers and put them away. but we don't police that nearly

as aggressively as we do other types of crimes, and it's long past time for that to change. >> i know part of your insight is informed by being a federal prosecutor like myself, and the idea -- you think there's a need for a preprioritization of things, opposed to focusing so much maybe on drug trafficking rings, you think the priority should be on drug trafficking. is that right? >> we certainly need some kind of shift. heroine and fentanyl have killed a lot of people in my community too, and we have to go after that. but i think you know there is still a lot of excess dollars in capacity when it comes to prosecuting non-violent drug crime in america as a result of the war on drugs. and the nra, in particular, has always battled the atf's budget and their capabilities. and that's just a fact. uk look at it today and the dea gets three or four bucks for every dollar the atf agents get. the atf agents i worked with were some of the finest police i

ever saw in my career. and if you gave them better tools, they could stop a lot of these guns from getting in the hand of people. look at this incident. 200 people at this party and they still haven't identified the suspect, which tells you people may not be talking. that happens a lot in violent crime situations. it's hard to chase down witnesses and reconstruct these crimes afterward. that's why you have to get in on the front end and stop the flow of these firearms. we have really common sense laws and proposals to do that. they pass the house every time and get stonewalled by republicans in the u.s. senate. >> the president has talked about the issue of ghost guns. obviously ghost guns are on the rise. they comprise the overwhelming majority of crimes people are seeing, but it's still an issue nonetheless. do you think that is part of the path forward, focusing on the idea of the non-serial numbers attached to them, trying to focus and hone in on the ability to construct these weapons? or is the problem part of the fact, congressman, that there are so many different caveats will give. they'll look at a mass shooting

at the tree of life synagogue, and they'll say that was an issue related to anti-semitism. they'll talk about a mass shooting at a party and say that might have other revocations. look at a school shooting in different ways. are we caveating ourselves out of common sense gun control by trying to compartmentalize the use and motivation of each shooter? >> yes, some people do that, but not me. i mean, my point is there's a common element tying all of the instances you just mentioned together, and that's the guns. and so we should -- we owe the public the ability to just have common sense laws that makes sure guns only end up in hands of people who are legally entitled to stlem. that doesn't mean you're going to stop every crime, but you would stop a ton of violent crime. the reason we are not very good at that right now is because of years and years of federal policy backed by the nra and pushed by the republican party for the most part that has made

us weak at this compared to other areas of crime. and there's a lot -- you know, there's a lot we need to do to intervene in the lives of these young people as well. you see that in many of the instances that are happening in our big cities. but it's all about prevention and intervention on the front end because as you can see right now in america, it's often times too late once these people get guns in their hands. >> prevention, better than cure. thank you, congressman conor lamb. i appreciate your time. >> thank you. you know, coming up, the app that's saving lives in ukraine. like so much else in that country, it's now a vital resource, far beyond what anyone could have imagined before this war. jim talks to a member of the team that developed it next. meets power? you try crazy things... ...because you're crazy... ...and you like it. you get bigger... ...badder... ...faster. ♪ you can never have too much of a good thing...

. >> the starkest warnings for ukraine right now focus on the east where new russian offensive is under way. but that does not mean the west is safe.

i'm in lviv. it was hit by missiles gist ho -- just hours ago. the air raid sirens have been sounding all day. president zelenskyy says if the eastern donbas region is lost to russia, kyiv could be threatened again. so how should the capital city remain vigilant? oleg pollvinko is the i.t. for the city council and he joins me now. olek, thank you for joining me. i want to get your reaction to president zelenskyy's warning connecting in effect the offensive in donbas to kyiv's safety. are you concerned that if donbas falls that could be another chance for russia to go after kyiv? >> good evening. yeah, you're absolutely right that this scenario can be -- can be done. >> i was in kyiv in the days

leading up to the invasion. at the time it was a peaceful place. places were open. it's been through many stages since then. what is daily life now in the capital? we hear of municipal i.t. employees like yourself carrying guns, not leaving their offices. how are you doing? >> of course the i.t. team carrying guns and preparing because we saw it a few weeks ago. the russian troops were quite close to kyiv, and our application was one of the information channels for our citizens because any other channels cannot help them. groceries and food through our store, from our application. >> this is remarkable for folks watching now. what your team did, they took a municipal app that's usually used for parking tickets, you

changed it so that, as you say, ukrainians could not just find groceries open, pharmacies open, but also use the internet in underground bomb shelters. how did you make that happen? >> yes, it was one initial team from the internet providers, and we asked them to help us to cover the bomb shelters, to cover it with internet with good connection to wi-fi. they help us and in almost one week we covered more than 800 bomb shelters with good wi-fi connection in cooperation with private and government and internet companies. >> did you ever think that you would turn a parking ticket app into something that people could use to save lives? >> yeah.

previously kyiv digital is the name of our municipal -- it was focused more on transport services, parking services, electronic and some information. they understand that we need many information for our citizens about air attack, about bomb shelter, where can go. so we redesigned the application and take out all unneeded in this situation, in war, and it function, and left only that which helps people to be in city, which is under attack in the war. >> one thing about this war that has captured the world's attention is the resourcefulness of ukrainians, like yourself, also the encourage, right? average people taking up arms, if they're not taking up arms,

they're finding ways to help the people taking up arms or doing things like you're doing, using technology to help in the defense of the country. what's behind that? how do ukrainians maintain the energy, the hope, to keep fighting like this? >> from my view, it's quite easy. we're fighting for our homes, for our lives. and from other side, of course technology helps us to be ahead and help our militaries and help our country to survive and to have -- i never imagined that kyiv digital will help to save lives of our citizens because previously it was for comfortable life. but now, yeah, it helps to save lives to people, and ukra ukrainians -- i'm not sure that

any kind of losses we can accept. we don't leave our homes and our land, so we will defend the land. >> well, the world admires your courage and your innovation. oleg, thank you so much for joining us tonight. >> thank you. we do have breaking news tonight here in ukraine. new drone footage of the southern port city of mariupol shows smoke rising from the azov stall steel plant. this is kyiv. this is one of mariupol's last bastions still under ukrainian control. cnn has geolocated an authenticate video but cannot confirm the day it was shot. we are watching it closely. we'll be right back.

jim, this is your second time back in ukraine. i'm just so curious about the resilience of the ukrainian people and the conversations that you've been having. >> listen, tough as nails,

right? we were out moments after four missiles hit this city, and people were already going back with their lives, going to work, driving through the streets, going to work and school. you see that, but you also see in their faces, i think, an understanding of just how long a haul this country is in for. you see it in their faces, and it's sad to see. laura, thank you so much. i'll be here in ukraine every night this week for "cnn tonight" and i have the pleasure that laura will be with me reporting from washington.
