right now, rescuers are desperately searching for nearly 300 people still missing after their ferry sank off the coast of south korea. many are high school students and teachers. they were on a class trip. we're going live to sooul, south korea. and back in the water surfing for malaysian airlines flight 370. we'll take you live to perth, australia. right now, tensions soaring in eastern ukraine. pro-russian militants trying to tighten their groups as ukrainian forces move in. we'll take you live to one of the towns caught in the middle of the standoff. hello, i'm wolf blitzer reporting from washington. we begin off the coast of south korea. where a ferry has capsized with hundreds of high school students aboard. the students were on their way to a resort island for a class

trip. at least four people are confirmed dead in the disaster. a figure almost certain to climb higher. 164 people have been rescued. right now, boats, helicopters and divers, they're frantically searching the frigid waters for the nearly 300 people. mostly high school kids who are still missing. this video which cnn cannot authenticate appears to show a scene inside the vessel as its sinking. it shows people with life jackets. andrew salmon is joins us live from seoul with the very latest. families are frantic for information. what is the very latest? what are you hearing? >> you're absolutely right, wolf, people are frantic, adding to the dimension of this tragedy and the early stages of the search and rescue operation. it was reported that a great number of people and all the students had been rescued, but as the day wore on, we discover this information was completely

incorrect. the majority of people are still missing and very large number of the students. i can't give you the exact numbers. the figures we've got the latest. i'll give you the good news first. good news is in short supply here. 179 people have apparently been rescued. 6 people are confirmed dead. between 277 and 290 are still unaccounted for. still missing. and it looks likely they're trapped in the sunken hull. the ship for unknown reasons had a sudden list, was still afloat for about two hours, a good time window for people to get off, then finally capsized, sank by the stern. the last we've seen of her, the ship, all that remains is just a section her bow protruding above the water. to reiterate, there's a large number, 277 to 290 people, the majority of them schoolchildren, young high schoolchildren,

possibly trapped under water in this sinking hull. >> basically, at least a little bit of that ferry is still above water, so the hope is that maybe some of these kids and others inside, they got to some space where there's an air pocket or whatever, where they might still be alive. is that the hope people are going through right now? >> that is the hope and i can't honestly tell you as a layman how realistic that hope is. we know about 170, 180 elite navy divers are on the sea. cometh the hour, cometh the man. these guys may be able to get into the hull under water, move inside this dark cold freezing labyrinth under the water and reach people trapped in air pockets. if they do reach these people, how they extricate them from that situation, this is an extraordinary dangerous and demanding operation for these

young men. so hopes are strong, but reality -- your guess is as good as mine. >> it's now after 2:00 a.m., cleeshly in the middle of the night over there. the search operation, the rescue operation, is continuing throughout the night, right? >> the rescue operation has very recently just been resumed. there's a u.s. navy ship on standby in the area. but there's a huge number of south korean assets circling the stairwell. if you look at the early pictures, you saw not just coast guard vessels but even fishing bo boats going up to the ship and taking people off at considerable risk to themselves. what happened is the ship listed very suddenly. so although it took two hours to capsize and sink, many of the people aboard, according to survivor's accounts, were unable to climb up these very, very steep decks and the water was

coming in, the lights had gone out. a nightmare situation. compounding the problem was an order which came over the p.a. system aboard the ship, telling people to put on your life jackets and stay where you are. in any maritime or naval disaster, the key thing is to get up from below, get top side, get on deck, where at least you can get into the water and possibly be rescued. so this order for people to stay where they are, not to move, is questionable. to say the least. >> it certainly is. all right, andrew, we'll check back with you. andrew salmon on the scene for us in seoul, south korea. let's go to perth, australia, in the search zone in the indian ocean, where an underwater vehicle is looking for any signs of flight 370. here are the latest developments. the submersible drone bluefin-21 resurfaced earlier today because of a technical problem but it was redeploy and is scanning the depth of the ocean right now. we could find out the results of

tests of an oil slick spotted by the ship "ocean shield." a two-liter sample was taken to australia for analysis. angry relatives of those on board flight 370 stormed out of a conference room at a beijing hotel today. they're so upset about the technical problems with the video conference by malaysian officials and that's only added to the anguish, the frustration, they've been experiencing now for the past 40 days. today's glitch was the second setback for the bluefin-21 drone, but what does this mean for the overall search effort? let's bring in our correspondent will ripley. he's joining us live from perth, australia. will, have the views been able to retrieve any data, significant data? they learned anything important so far in those two attempts by the bluefin-21 to go under the water and find something? >> all the data retrieved so far has shown there's nothing of interest in the areas searched. the bluefin-21 has had its

missions cut short twice now. dive number one because the depth of the water was too much for the equipment and its programming so it aborpted the mission automatically. on wednesday morn, glitch number two. we don't know the nature of the technical glitch. we haven't gotten an answer. we know the bluefin had to come back up. they took what data was on there, didn't find anything. as far as we know right now, the bluefin-21 is operating normally and perhaps number three will be a charm here to be able to actually complete a full mission. >> right now, that bluefin-21 is under water and they're hoping they've fixed the technical glitch, whatever that was, they hoped they reprogrammed it so it can go deeper than the first attempt. we have no result on try number three yet, right? >> yeah, because when the bluefin is down and doing its work, there's no real-time data sharing between the ocean shield and the bluefin-21. they have to wait until the device comes back up before they

can download that data. so after that they go through it, they look at the images, they look at the screen to see if there's any shapes that stand out as potential debris. so far what the bluefin has seen has not indicated anything like that. >> the oil from that oil slick, two liters that have been brought -- i don't know if it's arrived already in perth, where kemices are, chemists are taking it to a laboratory to see if it's from the jetliner. what's latest we know about its analysis if in fact it has already reached some sort of lab? >> as far as we know, it was due to arrive this afternoon in a matter of hours. so now here we are in the early morning hours and near the command center, the coordination center here in perth. as far as we know, the sample is now being analyzed or at least its at a lab where it will be analyzed. we're told those results could actually turn around pretty quickly. whether it's oil or some other hydraulic fluid, they're going to see if the fluid that was

found in the water would be a fluid that you'd find in that boeing 777 and if it was leaking from the surface. we could get answers soon. we have to wait and see. >> our viewers are obviously interested in knowing if that oil is from that airliner. thank you very much. let's go live to ukraine where we're seeing more extraordinary and confusing scenes play out. take a look at the map. uprisings are now taking place up and down eastern ukraine. russian troops, thousands, have massed on the russian side of the border. armed vehicles carrying the russian flag roll through at least two eastern u ykrainian towns today. a number of them apparently are ukrainians. ukrainian officials say some of the tanks were seized by local militia. here, dramatic pictures from donetsk. a local man risking his life from keeping armored vehicles

from getting any further. it does look like this man is trying to stop him, first by using his hands and then by lying down in front of the vehicle. our senior international correspondent nick patton walsh is in the middle of all of this. what have you been seeing today, nick? there have been some very tense, very dramatic moments. >> extraordinary day, the ukrainian army moving into one of the towns north of where i'm standing now in some number, running into locals who gave up resistance, blocked their path, and then it seemed pro-russian militants moved in and took those armored vehicles away from the ukrainian soldiers who were driving them. they then took them to slovonesk. we saw the separatist flags on these vehicles. and paraded them in the center of town for quite some time. the ukrainian soldiers

themselves, we understand from talking to the self-declared mayor, were surrendering themselves and then taken inside. there seems to be a pattern. very little sign of effective military presence on the ground. we've seen them on the skies, helicopters and jets near the airfield, but we actually went to another village near kramatorsk where it apeers a couple lum of ukrainian armor, 25th paratrooper division, considered to be some of the best troops that ukraine has, came into this village. we heard from a number of residents, claimed they'd shot in the air as they came through and even they -- that caused significant anger. many people came out, flooded around the vehicles, making it impossible for them to move. lengthy discussions at that point. a local police chief came down,

a veteran from the soviet war in afghanistan, tried to work this out. a decision was made between what's calling itself now between the donetsk people's army, the less prepared part of the pro-russian militants weem seen here. they had a discussion where they agreed the ukrainian troops would take the firing blocks out of their assault rifles. we saw them put them all into a large plastic bag, hand them over, and would then be allowed to leave. we didn't see the column depart but the atmosphere had calmed down. it is quite remarkable to see the ukrainian troops run that a village, meet such local resistance and then effectively give up. >> i was watching you earlier today on cnn and you were in front of one of those ukrainian tanks and there were a lot of people on top of the tank. you say it was peacefully handed over from ukrainian troops or at least one ukrainian soldier to these pro-russian demonstrators,

if you will, is that what i was seeing? >> well, what you saw on "new day," these images of pro-russian militants on top of an armored vehicle, those guys, they're not really peaceful in many ways. they are very well trained. they have top-end weaponry. they even told the self-declared mayor at one point to stop talking and get inside the building they were protecting. very organized which most people say is russian organized or russian led here. it appears the building we were at, people were surrounding those armored vehicles and potentially made a deal that would let them leave. for the most part, civilians. angry at the government in kiev who they say they don't trust. a lot of misinformation about the kiev government's intentions. certainly when it comes to the armored personnel carriers paraded, they it seems were confronted by pro-russian

militants and by peaceful residents too and at that point the ukrainian military seems to have made a decision, those guys traveling in the armored vehicles, to hand them over or give up control of them. i saw one go through his armed vehicle and take out some of his stuff from inside of it. those pro-russian militants very well equipped, pretty well trained, very disciplined and absolutely run things, took the vehicle, drove off. >> u.s. officials insist, many of them are actually russian citizens themselves, not ukrainian citizens. but that is disputed by the russians. all right, nick, stand by. we're going to get back to you. nick patton walsh on the scene. another major story we're following, the kidnapping of more than 100 schoolgirls by islamic militants in nigeria. even though the school had armed guards, members of the militant group boko haram were able to get the students on to vehicles and flee into the bush.

we'll have more on the efforts to rescue these girls. that's coming up later. our own christiane amanpour will join us live. also ahead, the bluefin-21 makes a deep dive in search of the missing malaysia airlines plane but what does the latest technical glitch mean for the entire search operation? ♪ norfolk southern what's your function? ♪

underwater vessel searching for malaysian airlines flight 370 is on its latest deep dive in the indian ocean now. a technical glitch caused the bluefin-21 to return to the surface but it was redeployed and is continues its search now. peter gohls is the former ntsb

managing director. tom fuentes is a former fbi assistant director. peter, first time they didn't program it right, the bluefin-21 couldn't go as deep as it should go automatically came back up. second tyime, unknown technical problem forced it to come back up. they think they fixed it. how much of a problem is there with this bluefin-21? >> this is a complex piece of equipment in a very challenging environment. don't think it's, you know, a big deal yet. they need to get it right. it's going to take a few shots at doing it. let's see how it finishes out today's assignment, but this is very difficult. >> the air search still continuing. they're still looking on the surface of the indian ocean for something. so far, 40 days, it's now day 40, they haven't found anything. at which point should they give up the air search and focus in where they heard that pinging sonar, that pinging device go off for two hours and 15 minutes and 5 and 6 minutes, four pings

from this general area. what point do they focus under water? >> i would think maybe now's the time. they haven't found anything ever, much less, you know, the last few days. and, you know, the amount of type and bad weather and all of the other factors of not being able to find anything after 40 days, it might be time now. >> sometimes you hear stories, tsunamis, weeks or months later stuff shows up on shore because it's moved across the pacific. you expect anything like that in this particular occasion? >> i agree with tom, i thirn the time is right, crews could be tired. i think at some point something's going to show up. but the time now is to focus under water. >> you have any confidence at all this oil slick, whatever they found, and it's now being examined, we should probably know later today whether or not it is from the plane or not from the plane, you suspect it could be from the plane, how serious of a possibility do you think

that is? >> i distribu . >> i don't know, listening to the expert, it's a long time for anything like that to sit on the surface and still be together, not having dissolved or some other factor. to me it unsos unusual that 40 days later you'd have an oil slick that collected together to be able to have it -- >> you agree? >> i think it's a long shot. >> certainly a long shot. let's talk a little bit about the families. once again, they're so frustrated, they're angry. in a conference call with malaysia and beijing. obviously, there were serious technical problems. you dealt with families on a lot of these kinds of investigations. they are still so angry. and so many of them are refusing to believe that this search is really being conducted in the right place. they want to believe and many of them probably still believe their loved ones are alive. >> it is a very challenging situation. the issue is, they've also received minimal compensation so far. just a single check.

they've got to figure out how to give the families some degree financial compensation. that doesn't replace, doesn't prevent them from suing but, you know, how unfair is it that they're sittinging there 40 days afterwards with sometimes their breadwinners gone, what are they doing? >> short of finding some wreckage from the plane, i don't think there's any way they're going to convince a lot of these families that their loved ones really are dead. >> i think that's true, i think they're convinced until they see something, some piece of evidence. >> if they're on social media, they see all these wild tales of where this plane really is, and many of them probably start believing it, not because they think it's true, they just want to have hope their love ones are alive. >> until we show the family members actual tapes of the twa wreckage and exactly how devastating it was, we had the same issues at twa. >> peter, guy, thanks very much. still ahead, another school in nigeria comes under attack

from islamic militants. this imttime, more than 100 gir kidnapped. we asked people a question, how much money do you think you'll need when you retire? then we gave each person a ribbon to show how many years that amount might last. i was trying to, like, pull it a little further. [ woman ] got me to 70 years old. i'm going to have to rethink this thing. it's hard to imagine how much we'll need for a retirement that could last 30 years or more. so maybe we need to approach things differently, if we want to be ready for a longer retirement. ♪

if we want to be ready for a longer retirement. mom has a headache! had a headache! but now, i& don't. excedrin is fast. in fact for some, relief starts in just 15 minutes. excedrin. headache. gone.

want to turn our attention to a developing story out of nigeria right now, where the country's military is desperately hunting for more than 100 girls who were kidnap from their school dormitories and taken into the bush on trucks and buses. the islamic group boko haram is believed to be behind the attack. in their attempt to create a strict islamic state.

our chief international correspondent joining us. boko haram has been especially ruthless towards these children. ways the greatest fear in these girls aren't rescued quickly? >> a huge fear, and the nigerian government has put a huge military detail on trying to find them as they continue to be missing, and what happens according to a lot the experts who have been tracking these kinds of abductions is in nigeria particularly these girls are often then sold into the sex slave industry or some kids are trafficked and become child soldiers. this epidemic, this crisis of child abductions, is battering nigeria and has been doing so since at least 2010, and boko haram is becoming even more active. at the beginning -- since the beginning of this year, something like 100 -- 1,500 people have been killed by boko

haram in nigeria. so it's a situation that's getting worse. even though nigeria's president, and i've questioned him many times on this, says they're doing all they can to try to stop it and to neutralize boko haram, the military tactics are blamed for actually stoking the flames of this crisis, because many critic, say that when the military goes in to try to either find abducted children or to tamp down these militants, they go out and sort of it's contin indiscriminately burn homes and attack people and that, many claim, the situation gets worse because of it. >> from this perspective of boko haram, this group, what does kidnapping young girls and selling them off as sex slaves, if you will, what does that have to do with creating a strict islamic state? >> well, you think those would be a contradiction in terms. first, the word boko haram means western education is forbidden,

it's basically against western education. so they target students, you know, saying this matches their mission statement so to speak. but then they want money. so this is a very, very lucrative industry, as you know, around the world. over $1 billion a year in the sex slave and sex trafficking. and that is a huge source of finance for these people as well. but beyond that, they're just trying to attack the fabric of those kinds of communities and put as much pressure on the nigerian government as they can. for instance, the government used to say boko haram's activities are only confined to that part of the northeast of the country where they started, but, in fact, in this last week alone, 70 people were killed in a bomb attack in the capital abudugi and more people are killed in the intervening days in other attack, so they're spreading their very destructive

capabilities. >> horrible, horrible story. cy christiane amanpour reporting. in the search for flight 370, why haven't the sophisticated gadgets found the plane? and tensions are heightened in ukraine. orred pro-russian separatists are taking over key buildings in key cities. can this be stopped? ameriprise asked people a simple question: can you keep your lifestyle in retirement?

welcome back. it's the middle of the night in south korea, where a race against time is under way to find nearly 300 people missing after a large ferry capsized and sank. most of the passengers were high school students from seoul on a class trip to a resort island. 179 people were rescued before the ship flipped over. 6 people are confirmed dead. survivors were treated for hypothermia after being in the frigid water. some rescued said they were given conflicti ining commands t whether to stay on the ship or jump in the water. >> translator: put your safety vest on and stay put as it's dangerous. kids were forced to stay put. only some of those who moved survived. right now, an undersea drone is scanning the indian ocean search for malaysian airlines flight 370. a technical glitch caused the

bluefin-21 to resurface during its latest deep dive but the problem was fixed and it was redeployed. ships and planes were out looking for any signs of debris on the surface of the water. 14 planes, 11 ships took part. angry relatives those on board flight 370 stormed out of a conference room at a beijing hotel today. they were upset about technical problems with the video conference call by malaysian officials. those technical problems with the bluefin-21 are troubling because searchers are relying on it to find the remains of that jumbo jet. brian todd is here with a closer look of what some are calling tickups, some are saying it's a lot more serious. >> the hiccups first. phoenix international official, they're the ones who own and run the bluefin-21, they say this is not unusual. it's not surprising this is a minor issue. what happened is the bluefin has electronics sealed in bottles to keep the saltwater out and to protect it from pressure. as it moves deeper into the

ocean, and the pressure rises, the system is designed to push oil into those little boths where the electronics are. in this case, the oil usually, you know, encountered the pressure and keeps the saltwater out. in this case, the oil in a battery junction box on the bluefin was low. the reading said it was low. they had to bring it i, replenish the oil, then sent it back in. they say that's not unusual for this kind of operation and that it's now back in the water and doing its job. so they say this is kind of to be expected in one of these operations. the bluefin is not the only option. there's something called the orion which is a towed vehicle. it can go a mile deeper than the bluefin. it is owned by the navy. right now, it's sitting in largo, maryland, in phoenix's facility. the u.s. navy says we've not been asked to send the orion over there. we have asked the people in perth, the officials of the search teams in perth why they

haven't asked. we've not gotten an answer yet. >> besides the orion, bluefin-21, there's other submersibles that potentially could be used. >> that's right. there is something called the rimas-6,000. it is a lot like the bluefin. autonomous underwater vehicle. it can go 6,000 meters, 3.7 miles below the surface. about a mile deeper than the bluefin. the problem is the navy, the u.s. navy, has three of these things, but they say all three are on military missions. they're tasked to do other things. the navy won't tell us anything more. we get the sense maybe it's classified. they say basically those are not available. now, what phoenix international has just told us is they're considering now tweaking the bluefin that's out there to be able to go 5,000 meters deep. that's 16,400 feet. a little bit more than 1,500 more than it can go now and about 3.1 miles down. this vehicle out there now in

the indian ocean, they can tweak it to go a little deeper. they're thinking about doing that now. >> brian todd, thank you. ukraine's government seems to be losing control in several eastern ukrainian towns. pro-russian separatists are taking over military vehicles, they're planting russian flags on them. should the u.s. be worried? what can the u.s. do, if anything? our military analyst stand , by.

in ukraine, tensions are high right now. pro-russian militants and the army are facing off in towns in the eastern part of the country. this is a map where the uprisings are taking place up and down eastern ukraine. all about 100 miles or so from where thousands of russian troops have massed on the russian side of the border. these are scenes today from near

cremetoresk. locals blocking a convoy of paratroopers acting on orders from kiev, the ukrainian capital. it appears standoffs like these aren't ending any time soon. let's bring in retired u.s. army major general spider mark, a cnn military analyst. it looks like the situation is getting more tense. the question is what, if anything, can or the u.s. military be doing about this? >> first of all, i think the united states has a very good sense of what's going on, who the actors are. there's good intelligence. i think we have a good view of the players and what's happening. and we really understand what's happening in eastern ukraine right now, not crimea, but in eastern ukraine, is entirely instigated by putin. i think we can attribute that to the russians. we need to be able to be very strong not only in our economic sanctions but we have to have an immediate impact. there has to be kind of a blow that putin understands. >> how does the u.s. do that? the sanctions are intensifying.

>> they are intensify and there's going to be a downstream effect that will be effefelt, absolutely. we have access to the black sea. we have forces that can increase its presence in the black sea. that's not unprecedented. >> that sends a message? >> a very strong message. that's very strong naval attack capabilities. putin understand that. we can increase air force press answer in nato. not just u.s. exclusively, but all nato forces. and we can get nato ground forces out of their garrison locations, they can begin to conduct exercises. then have the readiness, the wherewithal to send a very powerful message there's an increased readiness posture. we know what's going on and we have to demonstrate we're not afraid to act. >> no one wants u.s. military forces to go inside ukraine right now. >> i don't think there's much of a chance that's going to happen. >> short of that, putin is going to look at some exercises in the nato allies and other ships in the black sea, that's not going

to have a big impact on him. >> nobody said another ship on the black sea, it's a credible presence. we need to look at what putin is doing now with the forces across the board, not in ukraine, but across the border from ukraine. it's exactly what the united states did in 2003 before we invaded iraq. we gave up surprise, we provisioned our forces. >> my own sense is military options are very limited. to have an impact on putin where the u.s., the nato allies, the europeans, could have an impact would be economic sanctions, really making it economically painful for russia to be doing what they're doing. >> we could also release our ability to export our liquid natural gas. >> technically, that's going to be years in the making to get that kind of gas from the u.s. over to europe. >> we need to be able to have the eu leadership raise a hand collectively and say, you know, maybe we've been shameless for

the last 15 years, we've been in the pocket of russia, we can find alternative sources of keeping ourselves viable. >> they can but that's going to take years down the road. >> they have to demonstrate the ability to do that. they've got to demonstrate the confidence they can stand together and confront putin. this is not unprecedented what we're seeing. >> there's a lot of energy, oil, gas, coming from russia into germany and other countries. for the short term, there's really not much of an alternative for them. >> the short term has to be a very powerful message, it has to be sent to putin. i'm not suggesting u.s. boots on the ground is an alternative. >> it's a complicated situation. james "spider" marks, thanks. technology is leading the search for flight 370. one system is called sidescan sonar. we're going to show you just ahead. [ male announcer ] this is the cat that drank the milk... [ meows ]

...and let in the dog that woke the man who drove to the control room [ woman ] driverless mode engaged. find parking space. [ woman ] parking space found.

[ meows ] the internet of everything is changing everything. cisco. tomorrow starts here.

>> the search for missing flight 370 is using sonar to sweep the ocean floor and locate the plane. joining us now is stephanie off the coast to explain how the sonar system works. >> when you take a look at it, it is very tedious work. i want to introduce you to a

senior hydrographer. >> they come in all shapes and sizes. side scan sonar, they all work on the same principle. they are going emit sound, that sound will emit the sea floor. it will receive it and interpret that in terms of an image or 3d data points on what's on the bottom of the ocean. >> twice the av has had difficult difficulties. can you describe the challenges? >> it's nice to get it nice and deep. you have to navigate the vehicle, you have to have controls. there is a lot of complicated interfacing to get this sonar down near the sea floor.

it's very challenging. >> let's go inside. i want to take a look at how this looklooks. once the sonar is down there it has got to take some data back. >> the idea is to move the sensor back and forth in a regular grid pattern. we're moving along now. you see that we did one line previously. as you do you're building up a map of what's on the sea floor. we're seeing in realtime the auv. they only see it at the end of their mission. >> they are sort of flying blindly? >> in a way, yes. they will make their mission planning parameters based on general information. it may change the way they search. and they're going to have to refine the way they work. >> we know that sonars are being
