are now where everybody wants to do tv. >> sit down, you guys. >> no! >> no! >> oh, yeah, you can't sit there. >> why not? >> that's where sheldon sits. >> he can't sit somewhere else? >> oh, no, you see, in the winter that seat is close enough to the radiator so that he's warm yet not so close that he sweats. in the summer it's directly in the path of the cross-breeze created by opening windows there and there. it faces the television on the angle that isn't direct so he can still talk to everybody yet not so wide that the picture looks distorted. >> perhaps there's hope for you after all. hello and welcome to our viewers joining us from the united states and all around the

world. i'm laila harrak. u.s. president joe biden says ukraine doesn't need jets right now. what ukraine says it must have to pushback moscow's forces as the war grinds into its second year. and in east palestine, ohio, officials are going door to door to check on the health of residents after the toxic train wreck. we'll discuss the risks they could be facing. and a rare winter storm is bringing historic snow, dangerous flooding, and blizzard conditions to california. the latest weather report ahead. just days after observing the one-year mark of the russian invasion, ukrainians are noting another grim anniversary. the loss of crimea to moscow in 2014.

it's been a thorn in ukraine's side ever since, and every year is remembered on this date with a day of resistance. meanwhile, the latest package of eu sanctions against russia is getting high marks in kyiv. here's president volodymyr zelenskyy on saturday. >> translator: now new sanction steps are in the tenth package, powerful against the defense industry and the financial sector of terrorist states and against the prop band dyss who drown the russian society in lies and try to spread their lies to the world. they definitely won't succeed. >> while ukraine reports increased russian shelling up and down the front lines but says the russians have not made any significant gains on the ground. ukrainian troops say they can't push the russians back until they receive the nato tanks that are just starting to be delivered. the biden administration has made clear over the past year that it will provide just about whatever ukraine needs to defeat russia.

but it's been a hard no on sending advanced u.s. fighter jets, at least for now. cnn's priscilla alvaris with details. >> reporter: president biden said he is ruling out for now sending advanced american fighter jets to ukraine despite ukraine president zelenskyy asking for those jets as the country braces for an offensive from russia in the coming weeks or months. president biden spent the week saying that the united states will stand by ukraine, but as far as those f 16 fighter jets, he says he is still ruling that out, at least for now. >> we're sending him what our seasoned military thinks he needs now. he needs tanks, he needs artillery, he needs air defense, including another himars. there's things he needs now that we're sending him to put them in a position to be able to make gains this spring and this summer going into the fall. >> you don't think he needs

f-16s now? >> no, he doesn't need f-16s now. there is no basis upon which there is a rationale, according to our military now, to provide f-16s. >> you're not ruling it out? >> i am ruling it out for now. >> reporter: president biden is facing increasing pressure to provide advanced weaponry to ukraine, but this and has been a controversial one over concerns that it would escalate the conflict. the administration has said that they will stand by ukraine, and they're doing so by providing now a $2 billion package to the country as well as cracking down with sanctions to degrade russia's economy and discourage individuals from supporting russia's war in ukraine. all of this in totality, the administration says, to show its support from the u.s. and allies against the war in ukraine. priscilla alvarez, cnn, the white house. opponents of the war didn't hold anything back as they sent a message to both the kremlin

and the white house. >> shame on russia! shame on russia! >> this was the scene in washington where hundreds chanted "shame on russia" as they marked the first anniversary of the invasion. they also held signs berating russian leader vladimir putin outside the russian embassy. protesters marched near the white house as well, but they demanded more u.s. aid for ukraine. cnn's salma abdelaziz is tracking all this in london. with russia's full-scale invasion now in its second year, the ukrainians are asking for more military equipment to head off a russian spring offensive? >> reporter: absolutely, laila. although billions of dollars in aid have been pledged, have been sent to ukraine over the course of this one-year conflict, the united states alone, $113 billion pledged to ukraine, $2 billion of that on friday, marking the one-year anniversary

of the war. president zelenskyy is pleading for more. and he's not going to stop asking, laila, because you have to accept the reality here on the ground, that before this conflict, ukraine was facing a much greater military force from russia. one that had more manpower, more funding, more weapons. and what ukraine is trying to do here through its partners, through its allies, is have a qualitative advantage. face off a soviet-era military with more advanced weapons systems from nato and other partners. and that seems, of course, to be happening, but there is, of course, always a lag time between when something is promised, like leopard tanks, and when ukrainian soldiers are actually trained and able to use them on the ground to make a difference on the battlefield. and we're already seeing, according to ukranian forces, that they are struggling along

that eastern front. the city of bakhmut, a major flashpoint, ukrainian commanders say they don't have the means to fight back russian forces. i want you to hear directly from some ukrainian troops in bakhmut about what they need on the ground. >> translator: war is very difficult. there are a lot of people lost. we know what we are fighting for. every war has its price. we are paying the price. we are fighting for freedom. >> translator: we need more weapons. it is the most important. more tanks, artillery, armored vehicles. we have experience, but no tools to push out the enemy. >> reporter: ukrainian commanders on the ground there agree, they say they need tanks, armored vehicles, airplanes, long-range artillery. again, anything they can get their hands on. you heard there the controversy from our colleague around f-16 fighter jets, for now ruled out by the united states. take a step back and look at the bigger picture. some of these weapons we are

discussing that the west might be considering sending to ukraine, it was unfathomable a year ago that president zelenskyy would receive these. even long-range artillery at the beginning of the conflict was considered something that could aggravate tensions with moscow. now the west, of course, taking a very different position, willing to provide, they say, anything it takes for as long as it takes to fight this war and win back ukrainian land for president zelenskyy. >> salma abdelaziz reporting from london, thank you so much. federal teams are going door to door in the town of east palestine, ohio, to conduct health surveys weeks after a toxic train derailment. the u.s. environmental protection agency has also ordered all shipments of hazardous waste from the derailment to stop. all this after officials in other states complained they weren't told in advance the waste was being sent to their states for disposal.

cnn's polo sandoval has details. >> reporter: local officials in both the state of texas and in michigan feeling frustrated, many of them recognizing even though norfolk southern may not have been legally required to inform them that some of this hard zard does material would be disposed of in their communities, they at least would have liked to have been notified by that rail company. in harris county, texas, a chief executive there, lena hidalgo said she first learned about 2 million gallons of water used to fight the fire after the derailment, that it would be trucked to a licensed facility in her community. she learned about that after half of it was in harris county and she found out about it while watching the news. that's a source of frustration. texas molecular, the company hired to dispose of this potentially dangerous water, saying it is over four decades managing water safely. also contaminated soil, 4,800 cubic yards of it that the state

of ohio said would have to be removed and were already on their way to a disposal facility in wayne county, michigan, until elected officials raised concerns about them not getting word from norfolk southern. as a result, on saturday the epa put a temporary halt to the shipments so that they can further review the disposal plan that's in place. officials saying they have no reason to believe the water and soil is not being handled safely, they merely want to be informed, especially in a situation where information was very difficult to come by during the early stages of this incident. the epa recognizing that this hazardous material, it has to go somewhere to be disposed of, so long as it's safely handled. >> one thing that's been made clear to me is that everyone wants this contamination gone from the community. they don't want the worry, they don't want the smell. and we owe it to the i'm of east palestine to move it out of the community as quickly as

possible. at the same time, i know there are folks in other states with concerns, legitimate concerns, about how this waste is being transported and how it will be disposed of. epa will continue to work with our local, state, and federal partners to use our longstanding experience and expertise in these matters to ensure the health and safety and support the east palestine community and to hold norfolk southern accountable. >> the national transportation safety board out with a preliminary report on thursday which indicated that a wheel bearing failure was the likely cause of that february 3rd incident. it derailed 38 train cars, 11 of them carrying hazardous materials. ntsb adding last week that the crew was not to blame and saying that the incident was 100% preventible, though exactly what could have been done to prevent this incident from happening, authorities saying that answer may not come for several more

months. >> joining me from youngstown, ohio, to talk about the situation in east palestine, andrew welton, a professor of civil engineering and environmental and ecological engineering at purdue university. he's also the director of the healthy plumbing consortium and leads the center for plumbing safety. sir, a very good day. i understand you're headed to the impacted area tomorrow. what do you know so far about the risks that residents face as a direct consequence of this accident? >> thanks for having me. i am headed in with a team at the request of community members and groups to help them understand the water, soil, and indoor air safety questions that they're facing in their homes. >> do you know more about how

these chemicals are affecting the local environment? >> these chemicals are not designed to be moving around in the environment. so the toxic release on february 3rd was very significant. the fate of these chemicals in hopes and properties, also something we need to think about. that's what we're here to solve. >> the fact that you're there at the request of residents, if i understand you correctly, how concerned are they about the way that testing is currently being done? >> the initial response to the disaster by local state and federal officials was not optimum and resulted in a lot of misinformation and distrust. that distrust has resulted in many questions, in some cases people are just not believing the information that they've been given anymore. partly because the data hasn't been completely transparent and shown to them. so i have some serious concerns, but that's why we're here to help. >> can you share some of the concerns that you have?

>> yes. some of the concerns are the material that was created during the fires, the chemical fires. and that material deposited into homes, onto homes, into vegetable gardens and elsewhere. so nobody to date has characterized what that is. nobody to date has been swabbing surfaces to understand this particulate matter, what's it holding, what's it releasing? that's what we're looking at. >> how quickly were residents informed about the dangers? >> well, the evacuation was conducted by local officials, and that was done basically to prevent people from being exposed to the toxic gas cloud that was created during the chemical fires. looking forward, though, however, people were encouraged to come back to the community without appropriate testing, thorough testing that was done.

and that was probably a misstep on behalf of the officials. >> now, from what i gather from your answers, you feel that local authorities were ill prepared for this type of incident? >> well, this was a very significant incident. as it turns out, vinyl chloride trains go through where i'm from, west lafayette, indiana. these trains go through many places across the country. and officials likely haven't planned for this type of cascading disaster where a disaster come pounds on a disaster. this was a pretty significant event, but officials are learning from this now. >> in terms of water testing, how would you go about determining that, for instance, water is safe enough for people to use? >> well, after all the disasters i've been to, you need to understand what exactly you're looking for. so you don't just run what's called on voc test or svoc test. there's hundreds of thousands of different compounds, and if

you're not looking for the one you need to look for, it doesn't matter if you're sampling. that's what we're here to do is start screening the water and other samples for what chemicals they should be looking for, to kind of gut check the response. >> now, it's really quite scary for the people in the affected area. what is your advice to them? what can they do to keep their families safe? >> well, i always advise people that reach out that they need to take the best care of their friends and family. and so if there's an issue that they believe needs to be addressed, they need to tell somebody. they need to tell their elected officials and the governor's office. because the governor is responsible for the safety and well-being of the people in ohio. they also have to encourage researchers and scientists to come in who will help them get answers to the questions that they want answered. and i think that can help move them forward in terms of understanding safety, but also

help us plan for the next disaster as well. >> thank you so much, andrew whelton, good luck with your work. from heat wave to winter storms, extreme weather is sweeping the u.s. record heat continues along the gulf coast and florida. temperatures will be in the 80s through the weekend. but in some areas, it could reach 90. that's 15 to 20 degrees above normal for this time of the year. according to the storm prediction center, severe thunderstorms with damaging winds are possible from texas to illinois. western oklahoma is in the bull's-eye, a few tornados also possible. all this as a rare winter storm brought historic snow, dangerous flooding, and blizzard conditions to southern california. cnn's camila bernal has more now from just north of los angeles.

>> reporter: this is extremely rather for southern california. we have not seen some of these warnings in more than 30 years. over the last couple of days, a lot of snow, a lot of ice, a lot of rain and wind as well. many of the highways in the los angeles area have been shut down in the past few days. on my left is interstate 5. it is currently closed, and it has been mostly closed over the last couple of days as crews try to clean up that snow and the ice, as they continue to say it is extremely dangerous for many of the drivers. this is the highway that connects los angeles to san francisco. they're trying to open it but it has been difficult to do so just because crews are not used to dealing with this kind of weather in southern california. i want to walk through some of the snow just so that you can see the accumulation. it is nothing like you see in other parts of the country. the problem is that residents

here just don't know how to deal with this. many of the cars trying to get out have been stuck. to be fair, my producer's car got stuck as well. so we've been dealing with the snow. a lot of rain in the l.a. area, a lot of flooding. cars that have been stranded. and again, authorities just saying, if you can stay home, that's what you should do. this could be historic for southern california, and we'll have to wait and see the totals in terms of the snow and the rain. camila bernal, cnn, la beck, california. still ahead, thousands of afghan families split since the u.s. withdrawal from afghanistan are facing another big hurdle, navigating the american immigration system. details on that when we come back. when you take it again the next day. so betty can be the... barcode beat conductor. ♪ go b betty! ♪ let's be more than our allergies!! zeize the day. with zyrtec.

welcome back. the head of the world food program says the aftermath of this month's earthquake in turkey looks apocalyptic. david beesly toured parts of the quake zone on saturday. he described entire neighborhoods as being flattened and said the situation in syria

was a catastrophe on top of a catastrophe after 12 years of war. here's part of what he posted to twitter. >> i know you see behind me. this is absolutely unbelievable. you can see on television all you want, but until you get on the ground, see it, see how bad it is -- to think that everybody in this city, 1.5 million people, none of them have homes here anymore, none of them. this is devastating. >> the turkish government says it's already started rebuilding in the quake zone. all this despite criticism from some engineers and architects. they warn hasty construction could leave buildings vulnerable to future earthquakes. a year and a half after the u.s. withdrawal from afghanistan, thousands of afghan evacuees are still trying to reunite with their loved ones stuck back home. beyond the heartache of separation, they also face confusion and a lack of reliable information about the u.s. immigration system. all that as key deadlines to

stay in the u.s. draw near. cnn's natasha chen reports from los angeles. >> reporter: a daily video call is the only way ahmed can connect with his wife and daughter in kabul. we're keeping his wife and daughter's faces concealed for their safety. they're in the dark with electricity for only a few hours each day. when they could have been here in this small light-filled apartment in california. their family's sudden separation happened at the kabul airport during the u.s. withdrawal from afghanistan. after a year and a half, roman is no closer to getting his wife and daughter here. >> someone asked me about this. >> reporter: in mid-august 2021, the family and their relatives headed to the airport, knowing their safety would be at risk under taliban rule. but when they boarded the crowded cargo planes, they suddenly could not find their older son zaire.

his parents came out of the plane searching for him amidst the chaos. >> thousands of people on the ground. >> reporter: they finally realized he was already with another relative on a different plane. but by that point, his mother and sister had been pushed beyond the airport gates. >> i cry a lot. my family is inside the plane but they didn't let me on. >> reporter: roman waited, one of the last to board his plane. he is now a single parent raising zaire and rachman who's now spent half his young life in the u.s. >> i tell him, it's mom. but i know rachman don't know meaning. >> reporter: the tall lan requires male television for his wife to go anywhere, including the store, and their daughter may not be able to continue school. >> i'm worried about my daughter's future. >> reporter: it wasn't until january when the u.s. state department published a form for humanitarian parolees like roman

to apply for reunification assistance. several advocacy groups across the u.s. each tell cnn they're working with dozens of families in the same situation. one group, women for afghan women, trying to help 400 separated families. >> when i see my kids, but i cannot touch them, it's so difficult for me. >> reporter: we asked the state department how many afghan families are still waiting for reunification, but their press office says the number is fluid and they have "already resettled thousands of afghans, reunited families, and welcomed them into our communities across the country." >> you have filled out every form that you could. but nobody is telling you how long this could take? >> actually, no one tell me "we can help you." they told me, "we don't have answer for this." >> reporter: he says a team at the state department is in contact with him to try to help, but both he and his lawyers say there's no information about next steps.

>> we have one thing that make me strong, that's hope. >> reporter: not only are many families desperately trying to bring their loved ones here to the u.s., some of them are looking at an expiration date soon for their humanitarian parole status. for ahmad roman, that will happen in september. he's applying for asylum and temporary protected status, but he doesn't know how long that could take. he tells me he feels it could be years. natasha chen, cnn, los angeles. a cuban pilot just learned he can stay in the u.s. after a daring escape from the communist island. a judge has granted him political asylum. ruben martinez machado flew out of cuba in a soviet-era crop duster to an air strip 270 miles away in the florida everglades. he said he had been falsely accused of crimes in cuba but

the director of the cia hasek coed concerns from other u.s. officials china may provide russia with weapons and ammunition to use in ukraine. director william burns said, "we're confident the chinese leadership is considering the provision of lethal equipment," but he added, "we also don't see that a final decision has been made yet, and we don't see evidence of actual shipments of lethal equipment." joining me now is michael beckley, associate professor of political science at tufts university. he's also the coauthor of "danger zone: the coming conflict with china." a very good day, sir. so good to have you with us. the u.s. now says it has intelligence that the chinese government is considering providing russia with drones and ammunition for use in the war in ukraine. eu's top diplomats also express concerns about china's possible role in the conflict.

from an american perspective, what is the threat posed by china getting involved in russia's war? >> i think most immediately, it could shift the balance of power within ukraine itself. one reason ukraine has been doing so well is because it's received so much aid. if russia starts receiving more ammunition from china, it will be able to fight much longer. more broadly, it's just the idea that we really would be back to a cold war situation. effectively the war in ukraine would be very much a proxy war between the west, the united states and its allies, and now a russia-china alliance with an assist from other countries like iran, belarus, north korea. we'd really be back in a cold war situation here. >> it's quite an interesting development. from china's perspective, why get involved? it's not iran. it is fully integrated into the global economy. arguably its most important markets are the u.s. and europe. would they be prepared to alienate these economic blocs and deliver arms to russia for

its war in ukraine? >> i think china's trying to have it both ways. they can't really afford to let russia go down in a humiliating defeat or even worsen dismembered or destabilized, a destabilized country on their border. the autocratic vision that they're trying to sell to the rest of the world would be -- would take a huge blow. they would look like they let down a key ally after a war that got started right after they announced a so-called no-limits partnership. so china's credibility would also take a hit. >> were you surprised by beijing's so-called peace proposals for ukraine? what is china's track record when it comes to mediating international conflicts? >> i wasn't surprised because a lot of the content of that proposal are things that chinese leaders have been saying for many years now. it's basically the same set of principles, and they basically want to ratify russia's territorial gains in ukraine. >> what do you make of china's strategy in this case? is china now becoming a

political actor on the world stage, not just a major economic power? >> yeah, absolutely. china, this is just one area where china has been increasingly throwing its weight around. obviously within east asia, you've seen the situation with taiwan building out islands in the south china sea. basically trying to create an economic domain through its belt and road initiative. china's been on the offense for years now. so this is just part and parcel of that. it just looks like this is the hot war component of a broader cold war strategy on china's part. >> earlier on saturday, the chinese foreign ministry said the belarusian leader would pay a state visit to the country at the invitation of president xi. french president emmanuel macron now says that he will visit china in april to pressure it to not support russia in the war in ukraine. this flurry of activity, what does this signal to you? >> i mean, i think this is exactly what china wants,

frankly. they want to create the image that they are an honest broker of the war. and i think china probably would accept some kind of peace settlement that essentially leaves russia relatively stable. that's not so bad for china because even if russia's weakened, it just becomes more dependent on china. what they cannot accept is a russia that gets absolutely demolished in this war, has its military ground down into a meat grinder for years on end. china also has to worry if the war goes on, china's a major commodities importer, commodity prices are very much at risk in such a major war. just the tide of global instability could hurt china. i think china would want to find some way to end this, but it's certainly not willing to compromise any of the vital interests that it has at stake here. >> briefly, what drives this alliance between russia and china? is it driven partially by the u.s./china chief political competition? >> yeah, i mean, i think both countries, they're both revisionist powers in the sense

that there are aspects of the current international system they don't like. they don't like the way the maps are drawn. they believe certain territories -- ukraine, taiwan -- should belong to them, should be given back to them. they don't like the fact that the world is currently dominated by wealthy democracies that make it their business to harp on human rights abuses in the absence of democracy in their own countries. they don't like the fact that those countries also tend to violate the sovereignty of other nations in doing so. they're trying to create an alternative vision of world order that's built around a hierarchal, well-ordered system based on state sovereignty. so they stick together, they band together. for a long time, china has used russia as kind of the more belligerent, violent part of this alliance so that china can kind of hang in the background. but now it looks like china is willing to potentially put its muscle behind russia's offensive. >> michael beckley, thank you so much for joining us. greatly appreciate your insights. >> thanks for having me.

we don't know how many casualties russia has suffered in the battle of bakhmut, but we do know what it's been like for ukrainian troops. in many cases the first people to render emergency aid are foreign medics who volunteer to be on the front lines. cnn's sam kylie has our report, and a caution, some images may be disturbing. >> reporter: almost walking, this wounded ukrainian soldier has an obvious injury. arriving at a casualty evacuation point for the battle of bakhmut, american medics look for hidden trauma. >> i'm going to roll him, check his back. one, two, three. when you get a chance, give his legs a feel for me. >> shrapnel wounds out here as well. it looks minor. >> do you want to go ahead and draw that for me? >> reporter: chris is from houston, texas. he's three kilometers, less than two miles, from russian troops.

>> take the blood pressure for me. >> reporter: he's only 22. last year, he took time out from his job to volunteer for road to relief, the charity relying on donations to fund and equip front line ambulances. these teams are unpaid. >> there's credit cards, and my mom, a little bit of prior savings. as long as you have enough money to scrape by and just buy the basic goods, things tend to be okay. >> reporter: hospital and medical staff are regularly targeted by russia. this location is hidden in trees near ukrainian artillery. this firing overhead on russians just up the road. >> yeah, we need more medics, more trucks. it's just the amount of injured is super high. >> does he have any allergies? >> reporter: chris is saying privately, one of the reasons there is such a need for foreign volunteers to work as medics is so many of the ukrainians have been killed. the team relies on a former

software designer for translation. is there anything about this that you can't handle? >> all of this -- of course they're incredibly hard. hard to take. somehow you feel guilty about that. >> reporter: it's a 20-minute run for the ambulance to a field hospital. >> would you push this slowly for me, please? a mine roughly, what was it, 20 minutes ago, 30 minutes ago now? yeah, a mine 30 minutes ago. >> reporter: he's delivered to another secret clinic. here the wounded pour in. a soldier's lost a leg. in his abandoned uniform, the piece of shrapnel that took it. medics here say it's relatively quiet. some days there are hundreds of patients.

>> he doesn't remember if he lost consciousness or not. but pupils were equal and reactive, same size. >> reporter: blood-soaked stretchers dry in the sun outside. and sunset can be busy for medics -- soldiers trapped by fighting can be rescued as the light fades. back at the evacuation point, no wounded. five dead soldiers lie in body bags. they're so fresh from the battlefield, they're unknown. their i.d.s are checked and photographed. their suffering is over. their families don't yet know that theirs is about to begin. sam kylie, cnn, near bakhmut. there's more to come on "cnn newsroom." a key drug for attention deficit hyperactivity disorder is in short supply. how the scarcity is impacting those who need it. it went from gabe.

the drug adderall is commonly prescribed to people with attention deficit hyperactivity disorder. but it's been in short supply since october, and those who rely on it have been forced to look for alternatives. cnn senior medical correspondent elizabeth cohen has more. >> reporter: over the past few months, sometimes when patients show up at pharmacies to fill their adderall prescriptions, they're being told that there's none available. one such patient is clara pitts in utah. clara pitts is from a musical family. >> let's go ahead, just this section right there -- ♪ >> reporter: she studies hard at piano -- >> i've been using this spreadsheet since eleventh grade. >> reporter: a high school senior with a heavy load of ap
