>> the world must respond now. react prevent bring because after the use of weapons of mass destruction, any response will not change anything. >> a dictator that declares war and commits genocide.

>> translator: the military operation will continue until it's completed. >> mariupol will be defeated. >> the russians have come up with a new tactic to ensure the devastation of their attacks last far beyond first impact. this is cnn breaking news. it is wednesday, april 13th. we begin with the mass shooting inside a new york city subway in brooklyn. the city's mayor described it as a quiet tuesday morning that turned into a war zone. the gunman is still on the loose. authorities say he set off smoke grenades before firing 33 shots. ten people were hit though all survived. 13 others were injured by smoke inhalation, falling down or panic attacks. new york's governor says four children on their way to school were amongst those hurt. police have identified the man who you see here is a person of interest because he's believed to have rented a u-haul van

whose keys were found at the scene. he has not been named as a suspect. that van is being towed away. cnn's miguel marquez described the scene as authorities searched the vehicle. >> this is a few blocks away from the king's highway stop on the n train where one could have gotten on and continued to where the shooting took place. police have been going from door to door, both buildings, residential buildings and businesses looking at security video, asking for security video, seeing what else that they can find there to try to figure out where this individual is. it felt very much like they were on to something greater this afternoon. they had such a number of police investigators here. the bomb squad was here. fire, police and ambulance services as well in this area.

they were really on the hunt. you can get a sense how they swarmed this area and how they are looking for this person of interest in this case in other areas like this. >> a $50,000 reward is being offered. >> reporter: it happened during the morning rush. aboard a busy new york city subway train in brooklyn. shots rang out and smoke filled the car. witnesses say -- >> those people screamed for medical assistance. it was just a scary moment. >> law enforcement arrived within minutes. >> an individual on that train donned what appeared to be a gas mask. the train at that time began to fill with smoke. he then opened fire striking

multiple people on the subway and in the platform. >> reporter: ten shots, five in critical but stable condition with many more people injured according to the fdny as photos show blood on the floor of the subway station. >> we were stuck in the train right about to reach the stops and then thank goodness the train moved within a minute or i don't know what would have happened. >> reporter: a gun, multiple high capacity magazines, and they believe the gun jammed during the shooting. the suspect is still on the loose. >> he is being reported as a male black, approximately 5'5" with a heavy build. he was wearing a green construction-type vest and a hooded sweatshirt. the color was gray.

>> reporter: new york mayor eric adams is in isolation recovering from covid-19. he said it's too early to not call this terror. >> this is terror. they brought in what was a smoke device. they discharged a weapon. i don't want to be premature in identifying this was, was not. at this time the investigators are going to do their due diligence to properly identify what happened here. >> reporter: kathy hochul on scene called for an end to new york's recent wave of violent crime. >> no more. no more mass shootings. no more disrupting lives. we are trading heart break for people. it has to end and it ends now. >> brynn gingras, cnn, new york. one man wounded in the attack said it all unfolded after he unknowingly sat down next to the gun man.

he described the scene earlier from his hospital bed. >> walked in, sat down and the guy's next to me. all you see was smoke, black smoke bomb going off and people rushing to the back. a pregnant woman was in front of me. i tried to help her. i didn't know i helped her. she said, i'm pregnant with a baby. the bomb rush got pushed and that's when i got shot in the back of my knee. >> he tells us the pregnant woman he was trying to help did make it out safely. the attack has him so shaken he says he's not sure he can ever ride a train again. we'll have much more on cnn as the investigation unfolds. for the first time u.s. president joe biden is accusing russia of committing genocide in the ukraine. mr. biden made the comment when

talking about increasing gasoline prices and doubled down on the accusation later. >> i called it genocide. it has become clearer and clearer that putin is just trying to wipe out the idea of even being able to be ukrainian. the evidence is mounting. we'll let the lawyers decide internationally whether or not it qualifies but it sure seems that way to me. >> mr. biden's words were welcome by ukrainian president volodymyr zelenskyy who called them the true words of a true leader. military equipment is deployed on russian soil not far from ukraine's border. military convoys have been seen moving through eastern ukraine near the donbas. ukraine is bracing. they reported heavy fighting in the central zaporizhzhia area. fighting also continued in the besieged port city of mariupol.

the pentagon says ukrainian forces are still fighting back where local officials estimate more than 32,000 people have died since the war started. on tuesday the u.s. said it couldn't confirm if a chemical attack happened in ukraine but warned it could be a step they could take. >> this could be a tactic they employ which is to try to mask a potential more serious chemical attack with riot control agents. again, it comes from a mosaic of information we've gleaned. russians have certainly proven more than willing to use chemical pep ponce when it suited them in the past. >> russian forces have left behind a trail of death and

destruction in northern ukraine. on sunday six civilians were found in the basement in kyiv. a warning, the report contains graphic images. >> reporter: even as russian troops go to eastern ukraine, authorities in kyiv continue digging up bodies. painstaking work that goes hand in hand with investigating russia's attack on kyiv and possible crimes committed by vladimir putin's invading troops. prosecutor general ir irina benedictiva is leading the charge. >> for us, best motivation and we understand all ukrainians are

suffering. we document all evidence here in ukraine. >> reporter: french forensic investigators are now also on the scene, not because ukraine lacks expertise, but because kyiv wants to be as transparent as possible in terms of russian disinformation efforts. >> we want to do our job absolutely with standard of international humanitarian. that's why we have our international colleagues. we understand they can see everything. they can see real situation here, real dead bodies. >> reporter: after they managed to expel russian troops around areas they've occupied in ukraine, authorities have discovered scores of dead bodies. today another six found in just

one basement outside kyiv. the prosecutor tells me they are collecting evidence in thousands of cases. >> no, we start in more than 6,000 cases. it's crimes. war crimes. crimes against humanity, aggression crimes and we started on the first day so we started the case about genocide. >> reporter: all of this as russia says the forces have not harmed any civilians. on a visit to a space for the, vladimir putin claimed his forces are fighting against would-be ukrainian nazis in what he calls a, quote, special operation. the goals are absolutely clear and they are noble, he said. i said it from the beginning and want to draw your attention to that. there are some in the u.s. at the top level who spoke about a possible war crimes trial against vladimir putin.

is that something you ever think will be possible and that you're working towards? >> of course i think everyone understands who is responsible for this. that's why we do everything to document evidences but we are here in ukraine and actually understand who is responsible for all of this. >> reporter: the investigator's work is complicated by the fact the war is still going on. they can't reach many devastated areas like the enscircled city f mariupol where tens of thousands have been killed. irina says no matter how long it takes, she will push on. >> it is extremely important. if we will be successful as prosecutors, i will be sure we can stop such aggressions in the future. as fred was reporting, russian president vladimir putin

is defending his war in ukraine. volodymyr zelenskyy announced tuesday he wants to swap a detained pro russian politician for captured ukrainian prisoners of war. mr. zelenskyy warned they would capture more soldiers all signs this war is far from over. let's go to cnn's claire sebastian. so this politician is a ukrainian but he's being arrested on the basis he was found in fatigues? >> yes. and because he is known as very pro russian to the ukraines. it's someone moscow might install to replace zelenskyy. in his statement on his arrest he said he was a pro russian traitor and a member of the russian intelligence. they're saying -- zelenskyy is saying he would propose swapping

him, giving him to moscow for ukrainian prisoners of war. we have putin speaking in the far east of russia saying the conflict is far from over and this is difficult. >> translator: the military operation will continue until it's fully completed and the objectives are achieved. we are helping people. we are saving them from naziism in the first place and on the other hand we're protecting russia, taking measures to protect russian security. and it's obvious that we had no choice. it was the right thing to do and i have no doubt the object will be achieved. >> none of this inspires much confidence. the situation on the ground in many places -- he said the objectives set out at the beginning of the operation are

to be achieved. that's different than now. he was going to take control of the whole of ukraine. since then we know the focus has shifted to the donbas region where we see the military buildup. >> he's focusing on defeating naziism which harkens back to the memory of many in russia. these accusations of the use of chemical pep ponce. they keep coming back up. >> yes. what we're hearing, when it came to the commander of the azof brigade in mariupol. it's mostly destroyed. they say there was a chemical attack. on tuesday no one has been able to substantiate this. we have a reaction from the russian embassy in washington. they said this was disinformation, idol talk from the u.s. state department.

he said they were concerned and by a single piece of evidence. >> claire, thank you. still to come, storms moving across the u.s. have produced tornadoes, hail and snow leaving a lot of damage behind. the latest forecast after the break. plus, new details on the british prime minister's party gate scandal. some people are calling it a slap in the face, let't's say. neuriva. think bigger.

j just to the southwest. go, go, go, go. punch it. >> our meteorologist in the state of iowa. meteorologist pedram javaheri

joins us from the weather center. not over yet. >> reporter: not over yet. how about 150 large damaging hail reports. 2 1/2 inches across gilmore. notice rainfall, also significant. 2 to almost 4 1/2 inches. the concern is the severe weather threat is shifting a little farther towards the east. the population density picks up where upwards of 96 million americans brace for severe weather as we get into wednesday morning, wednesday afternoon.

the initial threat pops up into the early afternoon hours and eventually by late afternoon to the evening hours another line of the storm develops there. that could bring a few areas of strong tornadoes. that's a concern where you have a level 4 on a scale of 1 to 5. it's indicated in red. cities such as nashua, memphis, little rock some fall into line with the zone. in fact, the hashed area within 25 miles of a point could see tornadoes. widespread wind damage. as strong as 74 plus miles per hour in that zone. the good news here, max, the multi--day threat dwindles getting into thursday and wednesday will be the final day for the most active weather and storms will die down into the

next couple of days. >> back with you for an update tomorrow. thank you. president biden taking more steps to try to bring gasoline prices down. he announced an emergency waiver allowing year round sales of gas that contain a 15% ethanol blend. selling it is usually banned during the summer because of air quality. it won't solve all of the problems but the white house estimates it could save some consumers an average of 10 cents a gallon. 50 pounds or $65 is set to be the amount the british prime minister is fined for the party gate scandal. boris johnson apologized. he is the first serving prime minister to have broken the law or been found to have broken the law. >> absolutely. the reputational damage to the

prime minister, to his party is key here. we've heard the repeated calls since the lockdown parties sort of came to light and prepared for his resignation, and the resignation of other downing street officials. he issued a firm apology. he said he respected the outcome of the police investigation. they've been looking into numerous parties. the prime minister has been seen taking part in several gatherings. this is just one of them. he took part in a christmas quiz. he took part in a garden gathering at downing street all when the country was under lockdown or strict regulations. the party in question that he has been fined for was a gathering in the cabinet. he didn't know that he was actually at fault and in breach of covid regulations. take a listen. >> amongst all these engagements

on a day that happens to be my birthday there was a brief gathering in the cabinet room shortly after 2 p.m. lasting for less than ten minutes during which people i work with kindly passed on their good wishes and i have to say in all frankness at that time it did not occur to me that this might have been a breach of the rules but of course the police have found otherwise and i fully respect the outkcome of their investigation. >> the prime minister backed the met throw politan police investigation. he has paid that fine. the investigation is still ongoing. there could still be morphines to come. even though he has made that firm apology, people are asking for more, both from the opposition party and the public calling on the prime minister to

issue his resignation for not following the rules he and his party set out particularly when friends and family were abiding by the regulations. so many people dieing as a result of coronavirus. many won't be satisfied and will continue to call for his resignation. >> it's an advantage that he's the one that decides whether or not the ministerial code was broken and whether he should be fined. >> yes. >> thank you very much, indeed. video now shot from inside a covid quarantine center in shanghai. hundreds of people are crowding together in a large room. the patient tells cnn all 1,000 beds in the quarantine center filled up in two days. meanwhile, deputy director of china's national health commission says the covid outbreak has not been effectively contained. shanghai announced 20,000 new infections and more than 200,000

welcome back to "cnn newsroom." i'm max foster. following breaking news on the shooting. a gunman set off two smoke bombs. the gunman fired at least 33 times hitting 10 people. all are expected to survive. the credit card and keys to a u-haul van were found at the scene.

frank james is a person of interest. they say he rented a van which was later discovered in brooklyn. police say they don't know if james has any connections of the subway attack and they're not calling him a suspect. we continue to follow the story and bring you the very latest. european leaders are standing united against russia's war on ukraine. the presidents of poland, lithuania, latvia and estonia are on their way to kyiv. they're expected to discuss aid and the ongoing investigation into russian war crimes. meanwhile, the european union is renewing pressure on opec to look into increasing their supply of oil and gas in international markets. cnn's nic robertson joins us live from brussels.

>> reporter: the other reality is opec doesn't seem to be minding increasing the output as the european union has requested, as the u.k. has requested, as president biden has requested. russia, the second largest oil producer in the world. perhaps the biggest and strongest voice at the table at the opec plus the commission spokesman here said that the european union believes that has a key role to play. and without the opec nations doing more, the opec nations minus russia doing more to support that position and essentially come out against russia, make a strong position

against one of their larger members, the european union is in a bind. they continue to discuss oil. foreign ministers monday, europe ministers yesterday coming into easter. the real focus is nothing is off the table. oil and gas hugely important. oil four times larger in terms of imports and value to russia as well. the gas -- so oil is necessarily the big focus. as you say, there are so many countries in the european union that depend on russian oil. lets's take lithuania, president is on the way to kyiv, very big statement by going to kyiv. the lithuanians said, yes, we're the first to cut imports of russian gas. they are still forced to take russian oil because they're so heavily dependent on it. there isn't an alternative.

poland also very heavily dependent. perhaps he'll talk about that when they get to kyiv. these are the constraints. i don't think we're expecting a sixth round of sanctions for it to be heavily focused on that. >> those leaders are arriving in kyiv today. are you expecting anymore announcements? or is this a fact-finding mission for them? >> reporter: i think it's fact finding. i think it's important to continually -- for them to continually show and demonstrate to the ukrainians that they're supporting them. these four nations -- the president of these four nations that are going, perhaps the countries that have the most skin in the game, if you will, they have been the strongest supporters of strong military support for ukraine. a cause for the european union and others to take stronger positions against russia in

terms of sanctions. it's more than symbolic. you know, you have the support for the ongoing war crimes investigations but it is a strong message to the ukrainians that there is support and for these nations at least that are visiting today, they really would like to see ukraine brought into the european union sooner rather than later. >> nic in brussels, thank you. russia's economy is already on track to contract more than 10% this year as the biggest fall in gdp since after the soviet union collapsed. joining me is a former russian deputy energy minister and an ally of alexey navalny. he's currently living in exile

and living in lithuania. thank you for joining us. what do you make of the fact that europe is in this bind? if it can't get more oil from opec, it's in a very difficult position when it comes to reducing its dependence on russia. >> i won't say europe was totally unsuccessful in finding their supply. i also believe we shouldn't be talking about just one situation. i think this is moving towards gradual measures which will not be simultaneous. steel we'll see this week or soon, an import. they're alternatives. for instance, yesterday mario draghi announced a new deal with

algeria which is supposed to replace some of the russian natural gas supplies. i think things will begin moving very soon. >> so russia makes most of its money from oil but europe is less dependent on the gas? is there any chance putin might sit there and think, i'm not going to accept this. i'm going to cut off gas if they cut off the purchase of oil? >> i think it's roughly equal now because still it's not the end of the winter system, there is still a natural consumption and directly oil and gas currency flows from experts are comparable in size and if putin decides to cut off gas supplies,

russia receives a billion euros a day from european experts of oil and gas in total and it's a significant part of this currency. that will mean a lot of trouble. the russian economy, less ability to finance the military and the ongoing invasion. putin might be threatening such moves but i think if he really does that, that will be painful for himself in the first place. >> what he must be really worried about is defaulting on his foreign debt. that could -- we've seen it in the past, that could cause huge harm to the economy for years to come because he won't be able to borrow anymore money. what are the chances of that default and what impact it may have? >> i think the situation is very, very different from '98. we have almost a quarter of a century to go. there we were really dependent on international borrowing. we are effectively cut off from

global capital markets. so the news i hear about potential russian default on its bonds, i think this is impacted by russian government itself. it wants to sort of instigate creditors to put more pressure on western governments to ease the sanctions because russia has the money to pay. it voluntarily doesn't want to. i think right now what matters is this huge in flow of cash from exports of oil and gas. you know, international loan market is not as important for russia so i think here is where they can voluntarily default, do some harm to creditors. default now is not the same as 1988. >> thank you for your insight. the war in ukraine causing the world's trade organization to smash the trade outlook. a warning that the entire

community has to brace for the fallout. the wto is predicting a trade growth down 3% down from 4.7%. these estimates could change due to the fluid nature of the conflict. the war is threatening supplies of food, energy and fertilizers. the lockdowns in china are also hurting world trade. ukrainians trapped in the conflict zones are having a tough time escaping now. we'll have details on that and a live report from the ukraine/poland border. and of course, puppy-friendly. we don't like to say perfect, but it's pretty pererfect. booking.com, booking.yeah.

4.6 million have fled ukraine since russia invaded nearly 7 weeks ago. the vast majority of those refugees went to poland. it's worrying to see all of these people leaving the country but it's almost more worrying to see a slowdown in that because that means they're trapped in nasty parts of ukraine right now. >> reporter: absolutely, max. i'm at the pedestrian crossing of the border. it often takes days for them to cross through the country, cross through ukraine. sometimes they arrive here. i want to walk you through this so you get a sense of what greets them. you'll see one of the donations. they brought hand-me-down strollers. if they come across, they don't have a stroller or wheelchair, you can pick that up and that's what they might need.

this is a pedestrian crossing. i haven't seen anyone come across with a stroller. that's key. that's important for them. you're going to see this pet over here. it is a busy intersection here. mind all of these people in the high vis jackets. they're here to help and they're going to often toys to the children, pampers to the moms. another where you can see toothbrushes, basic supplies. if you weren't able to grab that before you left, you can grab it now. sorry for all of the dogs. people come across with their pets. sorry. two dogs barking here. when you arrive here, what these volunteers want to do is give these families a sense of security. they're going to come from this area, walk through all of the tents, be offered food, medicine, basic sprys if that's what they need. when they arrived to safety in poland, their journey is not

over. they have to figure out where they're going to sleep. they have to figure out if they're going to another city. this is a chance for them to grab what they need before they move again. max? >> in terms of how they're coping, is it the same level of support? are they getting backup? are they leaving? because a lot of those volunteers can't stay there forever. >> yes, emotionally people want to continue the support. when you talk about financially, that money is running out if not has run out. we've spoken to volunteers who say, look, they want to continue to provide shelter, safe havens, they simply don't have the cash to do so. there needs to be a long term play here. there's a different language here. how do you provide classrooms and jobs? the polish president is heading to kyiv and will meet with

president zelenskyy today. that will be at the top of the agenda. how do they continue to support over 2.5 million refugees and give them a more permanent sense of home here? max? >> selma at the border. thank you. the u.s. isn't sending troops to ukraine, but american military veterans are choosing to go anyway. coming up, how a retired marine colonel is training ukrainians to fight back. i'm jonathan lawson here to tell you about life insurance through the colonial penn program. if you're age 50 to 85,

the u.s. is expected to amass hundreds of millions of dollars in ukraine right now. a final amount hasn't been solidified. the package is expected to be worth close to $700 million. president joe biden says he will not send to ukraine active military troops. they are no longer in service. they're volunteering to go anyway. >> reporter: current u.s. service members are not in ukraine but u.s. veterans, they damn sure are. at an undisclosed location in ukraine, veteran colonel andrew

mill burn is training ukrainians to fight the russians. millburn knows what it's like on the front lines. an american who grew up in the u.k., he has served in somalia, libya, afghanistan and iraq. >> i went through the battle of fallujah. i would rather do that again than confront a 12 hour barrage of the russian military like we're seeing. >> reporter: having retired from the u.s. military in 2019, he works for an organization to bring in other special forces. after losing the battle of kyiv leaving behind devastation and evidence of atrocities, the russians are turning to the eastern flank of ukraine, what will likely be a series of large scale battles. >> ukrainian military at large is more adaptive like the u.s. military. >> reporter: this more open,

less wooded terrain can be more challenging. they're calling in targeted strikes in the north. mill burn trains ordinary ukrainians to fight in the resistance as well as training more elite ukrainian forces like n nikola. >> also because of your help we were quite successful with first attack. they leave not for their own reason, there was a lot of troops, tanks, armed vehicles. we were using modern european

antitank missiles. >> reporter: he knows what's to come. >> we need more. >> they need drones. >> even upgrading the basic equipment they have could make a lot of difference. >> they're coordinating by cell phones or motorola radios. that can be intercepted. anyone who's been in any western military will be astounded. >> reporter: weapons are not the only need. they need training. >> they lack medical training.

injuries that would be easily survivable by u.k. soldiers, they would be easily survivable. >> reporter: there is something purer about this fight, he says, than the others he has fought. >> frankly, you know, serving in iraq and afghanistan, there was always a moral ambivalence. there was always a feeling of being an invading army. even at the beginning of those conflicts. so there was always that dissidence between what put you into the military and what you are doing.
