tragedy as of now. so all that's real and definite and tangible right now are moments like this one. [ crying ] that's a ukrainian mom discovering her son's life less body dumped in a shallow well after russian forces left their residential town just 30 miles from here where i'm standing in kyiv. she is heard saying "my little son." she's hardly able to breathe because of all the sobbing. or take a look at this family. they tried to take an evacuation boat to safety with nothing more than a backpack and important documents. then russian rockets came raining down, turning the scene into a blood bath and killing the 12-year-old on the right of your screen there. vladimir idolized michael jordan and dreamed of playing basketball. then there was 8-year-old alisa who watched her grandfather get killed right in front of her eyes. ukraine's first lady first flagged the story and reports say the little girl's grandfather cradled her in his dying arms to protect her from the blast, and he gave his life serving as a human shield. alisa was also gravely injured and she too later died from injuries at a nearby hospital. this is what the russians are doing in ukraine. we're joined now by cnn's fred pleitgen. ukraine has endured seven weeks of war. it appears there will be another big battle in the east. you spoke with a ukraine national security advisor. what did he have to say? >> the ukrainians have no illusion this battle isn't going to be tough and bloody. one gave them a boost, the ship being hit but the security assistance they're getting especially from the united states and the fact there's heavy weapons among that security assistance. ukrainians are telling me they're already moving more forces towards the east and we also saw that firsthand as well. as vladimir putin masses his troops in eastern ukraine, the ukrainians too are deploying more forces to try and stop russia's offensive. these elite territorial defense soldiers gearing up to head east. we are absolutely prepared for this. we have both fighting spirit and fighting mood. we are patriots of our country and of course we will fight back the enemy, the soldier who goes by the name vlad, the rifle tells me. and now they have strug ck the flagship of putin's fleet, the moskva. >> can you tell us what happened to the cruiser moskva? >> reporter: it sank, he says jokingly. so far russia only acknowledges that the ship was damaged after a fire, and now moscow claims it sank while being towed in a storm. the moskva was involved in a now famous incident at a place called snake island when its crew told ukrainian soldiers to surrender. it was still there near snake island and was hit there by two powerful ukrainian made missiles, he says. and then a warning to putin. this is just the beginning, he says. there will be more than one moskva. but the leadership in kyiv understands the next major battles will be different and possibly even more bloody, as russian tanks and artillery pour into the donbas region. this horde has invaded our country and they think we will watch them destroy us. of course we will respond by all means we have, thanks to our international partners, we have interesting tools. the u.s. and its allies have already provided ukraine with billions of dollars worth of weapons and are now moving to give kyiv heavier arms to counter vladimir putin's tank battalions. the national security advisor says ukraine needs all the firepower it can get. i would never say that the russian army is weak, he says, given the amount of weapons thrown there, the number of tanks, armored personnel carriers, planes and helicopters. i would not say this is a weak army. i would say these are strong ukrainian soldiers who fight back such a powerful army. the national security advisor also tells me for ukraine the end game is clear. there will be no russian soldiers in this area, he says, neither in crimea nor on the territory of donetsk or h uluha regions. we are not going to give up. that's also what the territorial defense group pledges, ready to bring its forces to the east to confronting of the russian army once again. you can tell the ukrainians under no illusions as to what they're up against, the firepower the russians can bring and brutality they bring as well. but there is that boost of morale. they believe with that security assistance they may have a chance. >> fred pleitgen, thank you so much. with us to talk about it is john kirby. thanks for joining us. russia now says that its damaged warship moskva sank in the black sea. is there anything you can tell us to sort out the conflicting claims? russia is saying it was just a fire onboard and a storm sank the ship. the ukrainians said, no, no, we shot it with two neptune land-to-sea missiles. who is telling the truth here? >> well, we certainly can't -- we're not in a position to officially confirm independently what exactly led to the ship's now sinking. but we're also not in any position to refute the ukrainian side of this. it's certainly plausible and possible that they did in fact hit this with a neptune missile or maybe more. the neptune has a range that would have certainly been able to reach the moskva which was 60 to 65 miles south of the coast off odesa. so certainly within the realm of possibility there. but clearly as you said earlier, and this is a big blow to the black sea fleet. this is a cruiser, very, very capable warship with almost 500 sailors onboard. and a key part of their efforts to execute some sort of naval dominance in the black sea. so this is going to have an effect on their capabilities. >> i can't even think of the last time a ship this big sank in a military confrontation. i'm sure it's happened since world war ii, but nothing comes to mind. can i ask, given the fact that even the russians confirm that there was an explosion onboard, they say there was a fire and the fire hit ammunition they have, it's likely that russian sailors were killed in this incident, yes? >> i think you have to work on that assumption. almost 500 sailors. i don't know how many they got off. we did see indications that there were life boats and that some sailors got off the ship. but if it was hit by a missile, even if it was just an internal explosion that cooked off ammunition as the russians are saying, you're likely going to have loss of life and casualties onboard that ship. >> ukraine's military says that its special operations forces destroyed a bridge as a russian convoy was crossing near ckharkv in the northeast of the country. we've seen long russian convoys heading for eastern ukraine and the donbas region. they seem like ripe targets. do the ukrainians just have to sit and wait for this convoy to start attacking them? >> no, and i don't think they will. you saw in the north near kyiv where there was that vaunted convoy we've been talking about for so many days. the reason it got stuck is because the ukrainians hit it right at the front of the column and hit it throughout that column of vehicles. and i won't get ahead of the ukrainians or what they're going to do on the ground, but no, they don't have to sit and wait. they have the capabilities available to them. it's just a matter of what their battle plan is. and again, i don't want to speak for them. we haven't seen resupply or refit efforts of a quantity like we saw in the north just yet. we are seeing a convoy of vehicles coming down from the north, from russia down towards that town of isium. we assess it's north of there and hasn't made a lot of progress but it's full of command and control elements, enablers, maybe some helicopter support. clearly what the russians are doing is shaping, trying to set the conditions for success in the donbas for future more extensive operations. >> you're expecting a different kind of fighting, we all are, in eastern ukraine -- >> that's right. >> -- than we saw earlier around kyiv. the land is freer of woods and is more clear. how will the new supplies of arms from the u.s., from other nato countries, help with this fight that's coming? >> we think that the terrain there, which is a little like kansas, it's flat, it's open like you described, jake, will lend itself for the russians to use mechanized things in columns, shoert range and even long range fires. those are the capabilities you want the ukrainians to have as well. when you look at the new package the president authorized, artillery, a radar system to help them defend against russian artillery strikes as well as uavs and coastal defense vessels to help them in the sea of azov. so we're tailoring this package to meet the needs of the fight they have today because they are fighting in the donbas today and the fight we think is coming in the days and weeks to come ahead of them. >> how soon can you get those howitzers and other weapons to the ukrainians on the front lines where they need it? >> we're working on that right now, jake. we're looking at where they are and how fast we can get them there. from the time the president authorizes to the time we can get them into ukrainian hands has been in some cases as short as a week. we know that the time is not our friend. we know the clock is ticking here. we'll be working on this package just as fast as we were working on the last one. i suspect we'll start to have shipments flow here very, very soon. >> do you have to sneak them in? are you worried that if the russians see you providing these arms they will consider those american shipments to be legitimate military targets? >> they have already said that they would consider them legitimate targets. so what we're doing is being very careful about how these shipments are getting into ukraine, using various routes from different places and at different times, varying it appropriately. we're doing everything we can to protect the operational security of these shipments, getting them to ukraine as fast as we can. look, eight to ten flights are flying into the region a day, not all from the united states, but from elsewhere. eight to ten. and usually there are multiple sets of vehicles moving into ukraine by the ground every single day from various different locations. that has not been interrupted yet and we want to preserve our ability to deep that flow going. so again we're being very, very careful. we have not seen any interdiction attempts by the russians thus far. >> john kirby, thanks so much. appreciate your time today. coming up next, my conversation today with the chief prosecutor from the international criminal court. he discusses his plans to methodically review the evidence they are beginning to collect of russia's horrific offenses. plus, new claims of discrimination from ukrainian refugees now just trying to find a new life

delivery fee on our app. we're live from kyiv in our world lead. russian state media claiming a victory in the besieged port city of mariupol. this video allegedly shows more than 1,000 ukrainian marines surrendering to russian forces. ukraine is denying this report. cnn cannot verify if this is real or kremlin propaganda. still, mariupol has been one of the hardest-hit areas since the war broke out seven weeks ago. ed lavandera spoke with one survivor who has tried her best to deliver aid and offer support to citizens in hiding while running for her life. >> reporter: when the first bomb struck mariupol, katya thought her most effective weapon would be a gentle smile and the ability to calm terrified families. she lived in an underground shelter, coordinating relief supplies for the trapped civilians of this besieged city. >> reporter: so you're watching your city get bombed and destroyed. people are being killed. you decide not to leave but to help. >> it's horrible. they didn't allow even children to go out from the city. >> reporter: day by day, the video she captured showed life in mariupol unraveling. she lost touch with the outside world. none of her family and friends outside the city knew if she was alive or dead. life here was falling into an abyss. >> it was like middle age. >> like the middle ages? >> yes. >> it's almost like you could feel yourself running out of time. there was only so much longer you could stay in mariupol. >> i thought i will never go from mariupol until the end. >> reporter: on march 16th, katya evacuated. she recorded two short videos on her way out just before seeing a family walking on the side of the road, a mother, grandmother and two young girls. >> we had two free places in our car and we saw this family and we decided to help them. >> reporter: at one of the russian military checkpoints, they stopped in front of a soldier. >> and he show us, go out and after that he began to shoot. >> reporter: one of the bullets pierced the car over her head. but in the back seat was an 11-year-old, shot in the face. the russians realizing their mistake sent the girl to a hospital. katya now separated, traveled on without knowing if the young girl survived, until -- >> 1, 2, 3, 4, 5, 6, 7. >> reporter: cnn founding her in the basement of a children's hospital in eastern ukraine after surviving life-saving surgery. for katya, the relief is overwhelmed by the horrors of what she witnessed. >> i saw a lot of dead people, a lot of common grace on the street, for example, in my yard. and i started to believe that they were crazy because they were like maniacs. >> they were maniacs to you? >> yes. they're really crazy. like nazis in the second world war. ♪ >> reporter: after escaping, katya remembered the videos she recorded before the russians ravaged mariupol. ukrainians protesting outside the now famous theater that in a matter of weeks would be the site of one of the most grotesque bombings in this war. the theater still intact. the city's building unscathed. she sees the peaceful faces of families and children. the video is hard to watch. are these people alive or left in makeshift graves around the city? katya doesn't know, and for her there's only one way to deal with this haunting reality. >> i decided that i will cry only when ukraine gets to victory. >> reporter: jake, one of the hardest things for people like katya to deal with is there are still 180,000 people left in mariupol and the regions around that city. she escaped several weeks ago. she said it was already so dangerous, unimaginable to live in when the street fighting was going on. so hard for them to grasp just how much the situation there in that city has deteriorated in the days since they have left. jake? >> ed lavandera, thank you so much. earlier today in kyiv, i spoke with the international criminal court chief prosecutor, karim khan. he is leading the war crimes investigation here in ukraine. after touring northern towns of bucha, he said, quote, ukraine is a crime scene. >> thank you so much for doing this. appreciate it. so you have been going around the country. you've been to bucha, you've been to boriyanka. have you seen anything that surprised you? >> unfortunately not. i think we have all been seeing the pictures and reading the reports regarding the devastation, the human cost both to property but most importantly to civilians, men, women and children. and so it was an opportunity to see firsthand, to verify and try to start a process of collection. >> putin is out there saying it's all fake, it's all a hoax. you're seeing it with your own eyes. >> what we have to do, i think the job is to separate truth from falsehood. truth is always said to be the first casualty of war. there's competing narratives. there's allegations and counterallegations and this is why there's a role and important role for an independent prosecutor's office. we don't have a political agenda. we're not in favor of ukraine and against russia or in favor of russia against ukraine. we're in favor of humanity. >> and you're not in a position right now where you're asserting the russian military is committing horrific acts or war crimes or as president biden said, putin is committing genocide. that's not your role right now. you are an investigator getting facts, and you're not ready right now to assign blame one way or the other. >> i don't have the luxury of a politician speaking in generalities. we have to have evidence for every proposition we put forward and it requires deliberation, it requires some urgency to get to the truth. but we're committed to that. but the united states, russia and other powers established a principle in nuremberg that crimes are committed by men, not abstract entities. individuals who have power, whether it's rape, a gun, mortar, a shell or a missile from an airplane. there are obligations. people cannot under the laws of war do what they want with impunity. >> how is it possible to go from just holding a private or a sergeant responsible versus this is systemic. they were told to do this. and it goes up the ladder and you hold colonels, generals, commanders, president putin responsible. how does that work? >> the important thing is i think it's -- nobody is above the law. nobody is beneath it. but whether you're a private or a captain or a colonel or a general or a civilian superior, the basic principles apply to you. nobody gets a get out of jail free card, nobody gets a free pass. every individual must act with responsibility in their contact and there is a personal accountability. it's knonot a defense. superior orders is not a defense. it's not enough to attack a civilian object, women and children. >> so the reason that the nazis were able to be tried at nuremberg is because they were defeated. they lost. it is likely that however this conflict ends, putin will still be in power. russia is not a signatory to the international criminal court. neither is the united states for that matter. so how can we guarantee that there will be some sort of justice given the fact that russia is not onboard with the icc and it's likely that the kremlin and all its leaders will still be standing when this conflict is over? >> we can't be naive about things, we need to be realistic. but first things first. collect the evidence, preserve it, analyze it, make determinations based on what it shows. those determinations can be checked by judges. now, in terms of the surrender of individuals, this is an issue we've seen before. yes, you're quite right about the allied powers after the second world war. but many arrest warrants were executed in yugoslavia when hostilities were going on. so it requires collective will, it requires political will, it requires a sense of responsibility and not to abdicate that responsibility over the next period. i do believe with a collective effort, the law can be vindicated but time will tell. i take a pragmatic view. we have to and i have to as a prosecutor of the icc do my job. judges then will do their jobs and check and make determinations that we will respect. this great realization that a common front needs to be built based upon legality because it affects ukraine, but it affects all parts of the world because of the rules-based system and the principles of public international law that have to be rendered much more meaningful, not to judges in their gowns or advocates in the courtroom, but to the men and women and children that you see on the streets and refugee camps that are completely innocent and that suffer horrendous crimes time and time and time again. we tend to have not only short memories, but also an absence of shame. >> every year on international holocaust memorial day, i read these statements from leaders, never again, never again. and there's always a genocide going on, whether myanmar or any of the other places that you've mentioned. what do you say to somebody out there who says it's all nonsense. they say never again and then tens of thousands of ukrainians get massacred and the western powers just sit back and, you know, they send some arms but don't really get involved. >> i think it's incredibly difficult. you're spot on. it's a matter of shame that what you say is true, but it is. we can't be hopeless and give up hope because we have laws domestically and people commit murders and a whole variety of crimes. the issue should be collective will to impose these standards in practice. and it's about progress. yes, the world is full of contradictions and hypocrisies and double standards. i accept that. but generally if you look where we are today in terms of the relevance of international law and international criminal law, for all of its defects and shortcomings, i think objectively we're in a better place than we were in the 1980s or the 1990s. and i think if we keep working, if we don't give up hope but be realistic and try to improve the compliance with the law, we'll make progress. utopia doesn't exist in practice. it's about trying to keep progressing in a way that is meaningful and we don't stop. >> thank you so much for your time today. i appreciate it. >> thanks so much. thanks, jake. an impossible task of moving people and supplies throughout a country under

live in ukraine's capital city. before vladimir putin gave the order and the bloody invasion commenced 50 days ago, this country was little more than a name for most americans. it's actually a pretty large country. it's about the same size as texas. from here to the front lines in eastern ukraine or southeast to mariupol, it's roughly 500 miles. it's a bit quicker to get to than driving from el paso to san antonio or from dallas to brownsville. except here, fighting and russian checkpoints can make roads impassable. obviously since the war began, flying is out of the question. so the safest way to get around in ukraine, to get away from the russians and the havoc they're wreaking is by train. close to 6,000 war crimes being investigated. potentially tens of thousands massacred. and russia repositioning for a new assault. these ukrainians are not waiting for what's next. >> translator: a week ago we were thinking and hoping that it would stop. it will be calmer. but it didn't change. >> less than a week after russia bombed a crowded railway platform in kramatorsk, those lucky enough to evacuate on these trains believe the ride was worth the risk. with air travel nonexistent and unexploded bombs and russian checkpoints on the roads, trains remain the safest way to flee. >> translator: it's not only the question of shelling, but the question of safety that some people may come an just take you away. we can't stay. >> the baby and his mother are from zaporizhzhia but plan to wait out the war in germany. volunteers at the booth answer questions and help coordinate transportation and safe housing in germany, poland, lviv and more. where most want to go is back in time. >> translator: we want as soon as possible to continue living as before. >> vida and her husband are two of 4 million ukrainians the railway says it has evacuated since the russian invasion began. >> translator: people say on the internet that anything can happen, even here, so we hope it will be easy. we left everything behind. >> thousands and thousands of ukrainians fleeing their hometowns come here to the lviv train station. they try to get accommodations, they can get food here from the world central kitchen. there's a fire over there, a wood-burning stove heating up water. people have come with whatever belongings they can take and their loved ones just trying to get to someplace safe. away from the crowds at a smaller train station nearby, the most fragile passengers have their own carefully coordinated welcome. doctors without borders arranged this train. there were a few cars with kids from an orphanage. and now in these remaining cars, there are ten people, nine of them children. almost all of them wounded in the attack on kramatorsk. they are getting off the train and getting into these ambulances. this was not the arrival they imagined when they came to the kramatorsk railway station last friday. but after russians targeted the crowd on that platform, many of these passengers, these children, suffered shrapnel wounds so deep, surgery is required. their train to lviv is outfitted with medical equipment in each car as well as a team of doctors and nurses. one doctor was the e.r. physician on board for the 24-hour journey, overseeing some complex injuries along the way. >> a pneumothorax is air in between the lung and the chest due to a penetrating trauma of a blast. >> these are the kind of wounds that normally one expects to see in soldiers, not in children. >> you expect to see that in war-struck areas where civilians are also close to the firing line. >> pretty tough stuff to see kids hurt like that? >> it always remains tough, yes. >> he says his team has been going back and forth on these kinds of medical transports for ten days. this group of some of putin's youngest victims safe for now. and headed for more care. back at the main terminal, the trains keep chugging in and out and across the country, bringing ukrainians from the besieged south and the east to lviv where they can have the small luxury of a moment to cry. we were asked to not show you the orphans and to not show you the kids who were so critically wounded in the kramatorsk train station attack and we honored those wishes, but i have to tell you, that was tough to see. in the u.s. today finally the new investigation into what many
