♪ so we start with the murder trial of former minneapolis police officer derek chauvin. the main witness on thursday, dr. martin tobin, a renowned expert in pulmonary critical care. he testified george floyd died from a lack of oxygen after being placed on the street on his stomach with handcuffs, a knee on his neck and a knee on his back. dr. tobin saying even a person without medical conditions would have died. cnn's sara sidner reports. >> reporter:. >> that's the moment the life goes out of his body. >> reporter: the prosecutor's expert medical witness did not hold back. >> mr. floyd died from a low

level of oxygen and this caused damage to his brain that we see and it also caused a pea arrhythmia that caused his heart to stop. >> reporter: the renowned expert on breathing and lungs dr. tobin pointed to the officer's actions saying george floyd died because the officers created a scenario in which floyd's lungs were put into a vice-like grip. >> this was almost to the effect as if a surgeon had gone in and removed the lung, not quite, but along those lines. >> reporter: dr. tobin said four things caused floyd to stop breathing, including floyd's position on the concrete, allowing no room for his lungs to expand. >> you mentioned several reasons for mr. floyd's low oxygen. you mentioned one, handcuffs and the street, right? >> correct. >> you mentioned knee on the neck? >> yes. >> prone position? >> yes. >> and then the knee on the

back, arm inside. were those the four? >> yes, these are the four. >> reporter: the doctor also testified about whether drugs were the culprit that killed george floyd. as former officer derek chauvin's attorney has suggested. to that dr. tobin said floyd had not taken a proper breath for nine minutes and 50 seconds when paramedics finally got a breathing tube in him, and by that point carbon dioxide in floyd's body had reached lethal levels. >> what's the punch line? >> the significance of all of that is it's a second reason why you know fentanyl is not causing the depression of his respiration. so we explained by what you expect to happen in somebody who doesn't have any ventilation given to him for 9 minutes and 50 seconds. >> reporter: on cross-examination chauvin's attorney pushed dr. tobin on two main issues, the potential effect of drugs on floyd's body and his breathing, and his heart

disease. >> and that's going to affect blood flow into -- in a person, right? it's going to make the body work a little harder to get the blood through the body. >> no, not really. it's not going to do that. >> how does that affect a person's respiratory? >> you would expect that he would be complaining of chest pain and you would expect that he would be demonstrating a very rapid respiratory rate. we don't see either. >> reporter: the last witness of the day also a doctor, backed up dr. tobin's testimony that drugs did not cause floyd's death. >> when you watch those videos and we go through them, what is his respiration? he's breathing. he's talking. he's not snoring. he is saying, please, please, get off of me. i want to breathe. i can't breathe. that is not a fentanyl overdose. that is somebody begging to breathe. >> reporter: sara sidner, cnn, minneapolis. so many are now saying that

that doctor you heard there, the lung and critical care specialist, delivered really the most powerful testimony so far. our senior legal analyst laura coats is one of them. listen to her. >> this was by far the most compelling testimony we've heard in this entire trial and i'm including the very emotional testimony from the first week from nine year olds up to somebody over a half a century older, from police captain, lieutenants, sergeants, all of those people, nobody expect this had pulmonologist, if you didn't know what a pulmonologist was before today you know what it is now. he gave instruction in a compelling, persuasive way, he is a volunteer, not a paid expert, he has no essential skin in the game here, but what he did was actually illuminate an issue about the respiratory system, show the way that george floyd had been reduced to trying to desperately gasp for air, using his finger, knuckles,

shoulder, trying told straight his own body, talk being new dimensions we hadn't contemplated yet. >> of note here, reports from inside the courtroom say many jurors were actually touching the bones in their necks during that key testimony. now, president joe biden is saying enough to gun violence in the united states. on thursday he demanded lawmakers take action while unveiling a series of gun control measures he's taking. kaitlan collins has details. >> so, folks, this is just the start. we've got a lot of work to do. >> reporter: president biden taking his first executive actions on guns since entering office. >> gun violence in this country is an epidemic and it's an international embarrassment. >> reporter: following back to back shootings in georgia and colorado, biden announced the justice department will pursue new rules to address gun violence. >> i want to see these kits treated as firearms under the

gun control act. >> reporter: biden is seeking to curb the proliferation of so-called ghost guns that can be made at home without traceable serial numbers, while also proposing regulating stabilizing braces that make pistols more accurate. he is also asking the justice department to publish model red flag laws and nominating a new director for the federal agency that enforces existing gun laws. but the action right side modest compared to what biden promised on the campaign trail, he pressured congress to be more aggressive. >> he offered plenty of thoughts and prayers, members of congress, enough prayers. time for some action. >> reporter: house minority leader kevin mccarthy called biden's moves an attempt to trample over our constitutional second amendment rights which biden refuted. >> nothing i'm about to recommend in any way impinges on the second amendment. >> reporter: the president stopped short of sending his own gun legislation to congress as he urges lawmakers to focus on his infrastructure plan. >> the president believes that

there is a path forward to get this american jobs plan passed with bipartisan support. >> reporter: in a new op-ed manchin cautions that creates a precedent for partisan legislation that changes the direction of our nation every time there is a change in political control. and when asked about senator manchin's op-ed the white house says there are multiple lines in it that president biden agrees with, but when asked if he agrees with specifically manchin saying they should not be using this reconciliation fast track process to get legislation through without republican support, the white house said they would leave the mechanics of how these bills get passed up to leaders on capitol hill. kaitlan collins, cnn, the white house. health authorities in the united kingdom are urging the public not to avoid the oxford/astrazeneca vaccine. they say all three of britain's approved vaccines are safe.

that's after british officials confirmed the potential but rare link to blood clots. salma abdelaziz explains. >> reporter: british health officials are now rushing to reassure the public after it was confirmed that there is a potential link between very rare cases of blood clotting and the oxford university and astrazeneca vaccine. the uk health secretary saying this shows that the regulatory bodies, the checks and balances behind the vaccine, are working because they were able to detect very rare incidences, four out of a million. that is the likelihood of these very rare cases of blood clots occurring. however, it is of course causing confusion, concern and global repercussions with several countries taking steps to limit the use of this vaccine in certain age groups. australia say they are now going to have to recalibrate their vaccine rollout to give this vaccine to only those over 50 years old. italy as well now saying they are going to provide preferential treatment for the oxford university and

astrazeneca vaccine to over 60s. spain is going to pivot its plan giving this vaccine to only those older than 60 years old. in belgium it is now paused for anyone 55 years old and under. that's a few of the countries taking steps, recalibrating, recalculating their risk/benefit analysis when it comes to certain age groups, the likelihood that this very rare occurrence, very rare blood clots could happen versus how likely it is for someone to get covid to get hospitalized. the fear is as there is mixed messaging this could increase vaccine hesitancy, lower vaccine uptake and potentially prolong the pandemic, salma abdelaziz, cnn, london. the eu's vaccine chief says the region could achieve herd immunity from the coronavirus by mid-july. meaning 70% of the population should be vaccinated by then. right now most of europe, as you

know, is really 4% to 16% range and far from being fully vaccinated. the big push to speed things up comes after the world health organization says the eu's vaccine rollout had been unacceptably slow. >> we have now 53 factories working seven days a week, 24/24 and, yes, i could tell you today that we will deliver the number of doses which will be necessary to achieve 70% of the adult population being vaccinated by mid-july. in other words, it will be now in the hands of member states to make sure that in every single country of the eu the vaccination campaign will accelerate. >> so a call to action there pretty much for the member states of the eu. melissa bell is watching it all for us from paris. good morning, melissa. that statement on herd immunity in europe seems at once hopeful and really yet unrealistic given the challenges. what is the plan to try to make this happen in the individual

countries? >> reporter: well, there's been this concerted fortunate, first of all, at eu level to get more vaccines produced within the european union given all the difficulties that the eu found those first few crucial months in terms of deliveries of vaccines that might have been coming from elsewhere. so 53 factories now producing those vaccines that have been approved by the european medicines agency so they can be more quickly delivered here in europe. but as we just heard, it is -- there are two steps to this process in europe and that's really one of the threads over the last few months that explains why things have been so much slower here and more complicated than elsewhere. the european union is in control of procurement for a start and then the distribution of the vaccines for the member states then it is up to the member states to make sure that injections are actually getting into arms. so really saying that, look, it may have been faltering to begin with, the eu will get up to speed in terms of getting the doses in the member states, then

it's up to them. we've seen the last few days ramped up efforts in countries like italy, germany and france to do that, to take the vaccines they have and ensure they're getting them into veins faster than they were with interesting creative solutions being found. in venice they have a giant vaccination center on the outskirts of paris. the result is that there has been an improvement with france setting a fresh record only yesterday, more than 400,000 injections given in a single day, in germany a record set, more than 600,000 injections given in a single day. really member states there trying to make sure that they're getting better at getting to the people that actually need the vaccines, paula. >> and those names, those numbers you gave out are crucial because it will get them closer to the 3 or 4 million a day that they will actually need if they want to do this by the summer. thanks so much. now india has broken its record for daily confirmed coronavirus infections. the ministry of health reported friday almost 132,000 new cases.

that means the country has crossed 13 million confirmed cases of covid-19. the current spread is as rapid as the peak during india's first wave in september. now, not helping matters is a vaccine shortage. the health minister says several states complained they're running low with some districts in mumbai suspending vaccinations entirely. so the coronavirus vaccine rollout in the united states does look promising, but experts say it does still have to go much faster. while they are especially worried about children who play sports. with derm recommended peptides. hydrates better than the $400 cream. for visibly firmer skin. olay. face anything.

♪ so about a quarter of all adults in the united states are now fully vaccinated, that's according to the cdc, and that's about 20% of the total population. but health experts are warning of a potential surge because there's still a long way to go until the u.s. hits herd immunity. the focus is now on younger adults who have not been vaccinated as well as children. cnn's alexandra field reports on what experts have to say. >> i actually think that we are

in the middle of a fourth surge right now. >> reporter: about a third of americans have received at least one shot but health officials warn we need to move faster, much faster. >> we aren't going to be able to get enough people vaccinated quickly enough to keep the rest of the country from experiencing what we're seeing in the upper midwest and northeast. >> reporter: alarming surges in new infections as vaccines reach so many of the most vulnerable. nearly 77% of people over 65 have received at least one shot but covid-19 is taking its toll on younger people. not just spring breakers, also school children. >> clusters of cases in daycare as well as school sports, particularly team sports, which people engage in close contact without masks. i think that is what is explaining these surges of faces in young individuals. >> reporter: more than 75,000 new cases reported wednesday, hospitalizations are up in 18 states since last week and climbing higher, particularly among younger people, but new

research published by the journal of the american medical association shows an overall declining death rate among hospitalized covid-19 patients is likely not due to their age, but due to better treatments. giving hope perhaps to the families of the sick while so many others are coping with loss. >> as if the emotional part of it wasn't enough, to shell out that much money is just incredibly tough. >> reporter: that part will get better. on monday fema will start providing up to $9,000 per funeral for covid deaths. all 50 states are working to make anyone age 16 and up eligible for vaccinations by the april 19th deadline. biden administration is saying that any seniors who have not been vaccinated should go do that right now to encourage more older people to get vaccinated the city of new york is opening up additional walk up sites for senior citizens, anyone who accompanies them can get a shot as well. in new york, alexandra field,

cnn. u.s. congressman matt gaetz could soon be facing additional legal pressure. an attorney for gaetz's friend joel greenberg a key figure in an ongoing problems cushion and sex trafficking investigation says he's likely to strike a plea deal with prosecutors. cnn's ryan nobles explains what greenberg's involvement could mean for the congressman. >> reporter: for embattled congressman matt gaetz the news out of florida today was not good. >> i'm sure matt gaetz is not feeling very comfortable today. >> reporter: joel greenberg the former tax collector in seminole county and political and personal ally of gaetz plans to strike a plea deal. it could mean greenberg is ready to share damaging information about his relationship with the congressman. the fbi continues to investigate gaetz as part of a broader investigation into possible prostitution and sex trafficking crimes, including allegations that gaetz had sex with a 17-year-old girl. dwaets and greenberg are close

associates, the two were both once rising republican stars in florida. >> all right. all right. >> reporter: posing for photos in front of the white house and with trump allies roger stone. >> if joel were to run for seminole county i think he becomes the next congressman for the 7th district. >> reporter: greenberg is faces 33 charges of wire fraud, creating fake ids, stalking a political opponent and sex trafficking. the fact that he's ready to cut a deal could lead back to fwaets who has defined having sex with a 17-year-old as an adult and that he has paid for sex. his association with greenberg is what led to the fbi's investigation into gaetz's conduct. "the new york times" reported that investigators believe greenberg recruited women online where he paid for sex and that gaetz had sex with them, too. their close relationship was well-known in florida political circles. florida state representative anna escamonti said this voicemail was cringy.

>> my dear anna this is your tax collector, i'm up in the panhandle with your favorite u.s. congressman, mr. gaetz. >> hi, anna. >> and we were just chatting about you and talking about your lovely qualities and -- >> we think you are the future of the democratic party in florida. >> reporter: greenberg's attorney making it clear his client could be a big help to the fbi. >> he's uniquely situated. >> reporter: investigators are also examining gaetz's travel schedule, a trip to the bahamas, sources say the probe is looking into the possibility that women were paid to travel for sex with gaetz and others. gaetz declined to comment to cnn on the trip but a spokeswoman told cbs that, quote, representative gaetz has never paid for sex more has he had sex with an underaged girl. this has turned into a general fishing exercise about vacations an consensual relationships with adults. >> reporter: more signs that

congressman gaetz is not making any plans to resign, a statement today from his congressional office attributed to the eight female members of his staff in that statement these women saying that they support the congressman, that he's done nothing but treat them professionally and they do not believe the accusations against him. still remains an open question as to whether or not gaetz will be here next week when the congress reconvenes. i asked his office that question specifically today and they did not answer. ryan nobles, cnn on capitol hill. now the caribbean island of st. vincent is on red alert as emergency officials warn a volcanic eruption is imminent. these are the latest images from the seismic research center. emergency officials say the volcano's dome was heightened significantly in the past day and all indications are that molten lava is pushing towards the surface. patrick oppmann has more. >> reporter: residents of the island of st. vincent were

forced to evacuate their homes after being warned of, quote, an imminent volcano explosion. the prime minister of st. vincent and the grenadines declares a disaster alert after ee run testify activity was observed. clouds of steam were seen coming from the volcano following several strong tremors that were felt on the island on thursday. scientists said that kind of seismic activity that was recorded usually is associated with the movement of mag ma near the surface. evacuation orders were in place in about a dozen districts all on the island and cruise ships were reportedly being used to ferry people out of harm's way. officials said there could be very little warning before a possible eruption and that people would need to finalize their evacuation plans immediately. patrick oppmann, cnn, havana. for more on that we will bring in meteorologist derek van

dam. really good to see you. we just heard from patrick and i'm curious about this. he's talk being these tremors and i'm wondering officials say it's imminent, it's likely. how are officials sure about that given, you know, the activity of those tremors right now? >> well, the tremors, paula, are creating the seismic activity that's longer duration than a usual earthquake in and around the volcano. so this is given an indication to voluntarily con olg gists, so scientists that mag ma is trying to surface to the top of this volcano, even the dome of the volcano has started to actually increase in height. so that is a tell tale sign that this volcano is set and primed and ready to erupt. you're looking at the caribbean ocean, this is the windward islands and st. vincent island has one lone active volcano on the north side of the island and that's important because of what i'm about to explain to you. what has occurred here within

the past 24 hours is what is called an effuse sieve eruption, the lava has steadily come out from the crater, what they're concerned about is that there could be more of an explosive eruption sending volcanic ash and mag ma into the upper levels of the atmosphere being dispersed in a larger area around it and that is why they need to get people off of this island as quickly as possible because of the signs that they have seen. a little bit of the recent images before the sunset yet, the venting that has occurred, this is an incredible image. these are passenger vessels but notice the vessels edging closer towards the st. vincent region and grenadines. this is cruise liners aiding in the evacuation process, trying to take the thousands of people on the island currently right now. authorities have identified some areas on the island that are safer than others. if they are not able to evacuate, the wind ward islands.

the eastern facing sides of the islands will be a, quote/unquote, safer location because the winds, the predominant winds across this area will take if there was a volcanic eruption, i'm nent volcanic eruption it would take the ash and push it away from the eye left hand. kingston is an area they have identified as a relatively safe location if you cannot actually evacuate. that's what the volcano looked like earlier this morning, of course, we will be monitoring this story very close. >> i know you will be, derek. it's good to see you and thanks so much for putting the danger that they're facing on -- into sharp focus. now u.s. senator joe manchin is speaking about his relationship with president biden and the control he has over the president's agenda in a very divided senate. his exclusive interview with cnn ahead. do a lot of things.

but you never knew all the things a dog could do for you. and with resolve you never have to worry about the mess. love the love, resolve the mess.

so you're a small business, or a big one. you were thriving, but then... oh. ah. okay. plan, pivot. how do you bounce back? you don't, you bounce forward, with serious and reliable internet. powered by the largest gig speed network in america. but is it secure? sure it's secure. and even if the power goes down, your connection doesn't. so how do i do this? you don't do this. we do this, together.

bounce forward, with comcast business. president biden has unveiled a series of executive actions aimed at curbing gun violence in the united states, they include restrictions on weapons known as ghost guns which can be built at home without traceable serial numbers. he announced his nomination of gun control advocate david chipman to lead the bureau of alcohol, tobacco, firearms and explosives which hasn't had a permanent director in place since 2015. the president also had a message for congress. >> whether congress facts or not, i'm going to use all the resources at my disposal at president to keep the american

people safe from gun violence, but there's much more that congress can do to help that fortunate and they can do it right now. they've offered plenty of thoughts and prayers, members of congress, but they've passed not a single new federal law to reduce gun violence. enough prayers. time for some action. >> now president biden's gun measures came just before another mass shooting, this time in texas. a gunman killed one person and wounded at least five others. it happened at a cabinet-making company in an industrial mark in the city of bryan. a witness describes the scene there. >> i was with my co-worker and i heard -- i heard like boom, boom, boom, boom, boom, boom, boom. i said, oh, the machine got messed up again. so i tried to walk to figure out which one and when i start walking somebody grabbed me, she was like, no, no, no, we need to run because there is a shooting going on. he didn't start shooting like

each one he just start picking who he was going to shoot. that's what they told me. now a trooper with the texas department of public safety was shot while pursuing the suspect and is in stable condition. police believe the suspect was an employee of the business, he is no you in custody and has been charged with murder. no motive has been determined as of yet. now to another mass shooting we're following in the united states. this one in south carolina. police are searching for a motive after they say former nfl player phillip adams shot and killed five people at a home in rock hill on wednesday. investigators say adams was later found dead after hshothim. the victims included a beloved local doctor, his wife and two of their young grandchildren. two workmen were also shot, one was killed and the other is still in critical condition. police have not been able to verify if adams was a patient of the doctor. when it comes to gun control and other measures that mr.

biden wants there's one man who may hold their fate in his hands, west virginia senator joe manchin. crucially he says he opposes weakening the filibuster, the senate measure that effectively requires a super majority with a -- for a bill to actually pass. it's become a stumbling block for many democrats. lauren fox spoke with senator manchin. here is her exclusive interview. >> reporter: the other joe who holds the power in washington. clear and unequivocal tonight. >> i'm not killing the filibuster. >> reporter: the reason senator manchin tells cnn the insurrection at the capitol. >> january 6 changed me, i was very clear with everybody. i never thought in my life, i never read in history books s s e our form of government had been attacked at our seat of government which is washington, d.c., at our capitol by our own people. now, the british did it, but not americans. so something told me, wait a minute, pause, hit the pause

button, something is wrong. you can't have this many split to where they want to go to war with each other. >> reporter: insisting the only way to move past the animosity is by working together. >> i think we can find a pathway forward. i really do. i will be sitting down with both sides and understanding where everybody is coming from. we should have an open, fair and secure election. if we have to put guardrails on, we can put guardrails on so people can't take advantage of people. i believe there are republicans that feel exactly like i feel. >> reporter: how does that affect his relationship with the white house? >> they've been very, very kind in talking. we do talk. we have communications. >> how often? >> as often as i would like, as often as they would like. i'm always -- >> the president directly? >> whenever he calls me he calls and we have a good conversation, we have had a good friendship and relationship for a long time. we understand each other. >> reporter: and he has a warning for fellow democrats, slow down on tauts of ramming through legislation like voting rights. >> some progressives think that you're standing in the way of

significant changes the president could make on voting rights because you don't want to get rid of the filibuster, other changes that they could make on gun reforms. >> that i can make all these changes if they try to work towards the middle. you can't work in the fringes. you just cannot work in the fringes. we want fair, open, secured elections and georgia has done some things i thought was atrocious, okay? but i'm also been a secretary of state and i've been a governor and i know the 10th amendment, i know my rights as far as states rights and i don't think there should be an overreaching, if you will, federal elections. i think -- i will tell you the one they did which is unbelievable to me, they took away the powers of the election secretary of state's office and put it in the hands of the congress. i mean, in their legislature. now you have no one person that you can hold accountable for, you have a whole legislature of 100 people or more. that's crazy. >> reporter: and gun control. >> i support what the president did today. from what i heard. okay?

what he's doing on executive order. now, there is an awful lot of things that he talked b but the executive order says ghost guns should not be allowed to be legally made or sold or used. it's illegal. because they're making them off of printers and you can't detect them. >> you still can't support the house passed background check? >> not the way the house s that's negotiationes. >> has there been any negotiation as soon as. >> we haven't gotten the bill yet. i'm happy to work with them and i will sit down and i think that we call it common gun sense and if you come from a gun culture such as i do in west virginia, i don't think there is a person -- i don't know a person without a gun, okay? it's a different background. i'm anxious to work with them and try to do something in a most constructive way. >> reporter: what does he think of his new found role as rain rainmaker? >> some of your colleagues joke that you are the president of the senate now, i've heard them in the hallways remark that to you. do you like this role? >> i've said this before and i will say it again, i've watched

people who have power and abused it, sought power and destroyed themselves and people that had a moment off time to make a difference and changes things and used it. i would like to be that third. >> reporter: while he may not like the role he's been given he says he knows he has a real friend in the other joe. >> i'm so pleased to understand that we have a person sitting in the white house that understands legislating, understands how congress works and should work and understands that basically we've got to represent the people that we represent and i'm representing west virginia to the best of my ability and i'm trying to speak for my state. >> reporter: and manchin also making it clear in the interview that what he wants to see is some negotiations also with his democratic colleagues. he told me when he gets back to washington he wants to have a discussion with senator rafael warnock of georgia. warnock has been pushing manchin to get rid of the filibuster when it comes to legislation dealing with voting rights. manchin has said that's something he's not willing to do but he does want to sit down and have a conversation with his

colleague, but this interview really underscoring what a linchpin for biden's legacy, for biden's legislative agenda manchin is right now. i think manchin making it clear that while he's not always sure he wants to be in the spotlight, he feels like in this moment, this is the place where he has to be. for cnn, i'm lauren fox, in west virginia. now negotiators are getting ready to meet in vienna for their next attempt at reviving at iran nuclear deal. this comes a day after iran's top negotiator met with the head of the u.n. nuclear watchdog calling their talks a thorough exchange but iran has insisted there will be no break through unless the u.s. lifts sanctions. nick paton walsh is covering this live from london for us. so we continually hear that refrain from iran. no deal if the sanctions aren't lifted and yet the state department has said, in fact, that they are willing to lift sanctions on iran that are in

its words inconsistent with the nuclear deal. does that really mean anything? what are they getting at there? >> i think that is a reference to the sanctions that were enforced, dumped upon iran by the trump administration frankly in a bid to make it very hard for the nuclear deal to be revived by any subsequent u.s. administration. now, nothing has been specified about what these inconsistent sanctions might be, but they are -- do relate normally to terrorism sponsored by iran itself. what's interesting is how these messages are being sent in public. we've had one meeting in vienna and most likely continued back door negotiations with the europeans kind of shuffling between the u.s. and iran and, of course, today they resume as well. but we have heard that over the weekend the u.s.'s key negotiator here for the iran deal will be going back to the u.s. most likely. he can always return afterwards but this is frankly what many

expected. brinksmanship, some public signals given being, private signals being given with many feel is the slightly inevitable fact that they may end up coming to some kind of arrangement here. interesting today to note that south korean tanker, which was seized in january by the iranians, accusations of pollution held in the port, that was released early this morning and many are seeing that as a bid by iran to say to south korea that holds billions of iranian funds to start releasing those and there have been suggestion that is up to this $7 billion worth possibly might find its way into accounts that could be used for humanitarian purposes by iran. all of what many would say confidence building measures here. you have the u.s. overtly saying it might take off some of the sanctions placed on over those which were reinstated when the trump administration pulled out of the nuclear deal. there's a lot of very complicated moves here involving

trust, involving who goes first but essentially it does seem that the diplomats have it in their will and competence to find a kind of timing which may suit them both. this south korean release of a tanker this morning a design that this is beginning to filter into the real world, the practical world. a lot could still go wrong, paula. remember, we've seen accusations by the iranians that one of their tankers was attacked just off its coast recently and the saudi arabians are demanding a seat at the table. many in the region possibly want to disturb this coming to fruition but it seems tehran and washington know what they want to get, the request he is can they get there fast enough and efficiently enough to suit the parts of their body politic and different capitals. >> the posture on all sides has been much different in the last few days. thank you. covid vaccines are a hot commodity and online scammers are trying to cash in. but beware of what's offered on the dark web.

>> if something looks too good to be true it probably is. this is what's preyed on, this feeling of desperation. it even kills the covid-19 virus. science supports these simple facts. there's only one true lysol. lysol. what it takes to protect.

i know i don't have to remind you of this, the wait for coronavirus vaccines can, of course, feel agonizingly long, but no matter how desperate you are to get that shot, don't try buying one online as anna stewart explains, criminals are active during times of crisis. >> reporter: available now, satisfaction 100% guaranteed. ads claim to go sell authentic covid-19 vaccines found on the dark web. >> we can see more than three times more vaccines that were on offer in three months. so it's constantly going up. >> reporter: cybersecurity firm checkpoint has been investigating covid-related ads on the dark web for months. >> initially it was the medicines, how to treat it, then we found the vaccines and more
