Russianback separatists who control the area continue to block the investigation. They have prevented International Investigators from gaining full access to the wreckage as investigators approached, they fired their weapons into the air. The separatists are removing evidence from the crash site. All of which begs the question, what exactly are they trying to hide . Right now just after 9 00 p. M. At the site where this passenger plane was shot down, and as i come to you right now, we have been watching and so many of the world really has been watching this train carrying wagon after wagon with bodies. It has just been released by the prorussian rebels, disturbingly, this eerie makeshift mobile morgue, if you will, had been held captive by these rebels. Ukraines president talking about this with cnn just a short time ago. We are still missing 16 bodies of the innocent victims of the terrorist attack which happened 96 hours ago in ukrainian sky. But the rest pro from the 298 victims is already in a refrigerator train, which was supplied by the ukrainian government. But still blocked in the territory, controlled by the separatists. This train now making its way to the ukrainian city of harkive. As for the sprawling crash site, it is a contaminated crime scene with militants reportedly granted almost you been unfettered access. In fact, youre looking at pictures, which appear to show rebels. Here you go. See the orange flight recorder . Holding the planes black box. But we are now hearing these flight data recorders will be handed over to malaysian investigators within the hour. Joining me now from donetsk, a spokesperson in cooperation in europe. Michael, lets just begin with this train carrying those bodies. What is the status of the train as we speak . Right. Good to be with you, brooke. As of about an hour and a half ago, we observed our special monitoring mission, the sealing of the fourth and final car of that train. We were told that more or less between 250 to 300 bodies had been loaded into there, the last of which were just really a few hours ago. And all four wagons were sealed. We were joined by forensic experts, three of them from the netherlands. And, you know, the train was basically good to go. But however, we cant say whether its moved or not until we actually have seen it with our own eyes. And obviously its something well be keeping an eye on in the next few hours. You know, michael, as far as the politics of this train, i had read the Prime Minister of the netherlands said it was your group, ocse, who were the ones negotiating with the rebels to move the bodies out of this conflict zone. Is that correct . And if so, can you just tell me how difficult, how challenging that process was . Well, you know, brooke, weve been on the ground here for three months. Weve got 250 monitors in 10 cities, including donetsk. So we were pretty familiar to them, if i can put it that way. Weve also had colleagues kidnapped here, which they helped, you know negotiate the release. So its an interesting relationship, but one that, you know, actually works in terms of getting things done. Weve had fairly good access between here and the crash site. We get there very quickly. When were there, they provide us with good perimeter security. And in terms of the train, well, we do talk to them daily. And we have impressed on them how important it is, especially for the folks who have lost loved ones, to get those bodies, and those remains moved as quickly as possible. You know, do you know, can you tell me definitively, where this train is going, and how those bodies i cant help but think about these families, be it burial or final rights to be read for these sons, daughters, husbands, wives. When will they finally get to their final resting place . Right. Well, you know, its i can put it this way almost a lodge and might mare, compounded that today right behind me there were there was heavy fire at the donetsk train station. Which presumably this train would have to go through. And i understand there is track damage and even fatalities. That could complicate things slightly. Having said that, i get the sense that they do want to move fairly quickly. I dont think they would have allowed the sealing of the doors if that was the case. So what im hearing, and its tough, because its windy where you are on the roof of this building, michael, as were speaking. If you could move your microphone a little closer up your jacket as i ask you this next question, which is, as you point out, the difficulty in even the train tracks and whether or not it will get to that final destination, because of the fact that this has happened in the middle of this war zone. I was just reading how i believe it was the New York Times a reporter on the ground described this recovery effort as a bunch of incoherent, untrained people. Not, of course, your group, but others, coal miners tasked with this scene. Have you ever in your years seen anything like this . Ive never seen anything like this. But, you know, we our First Priority was really helping this whole situation, the families in terms of making sure in fact, brooke, the malaysians made it clear to us, anything you can do to help us, that these bodies are given the dignity they deserve. So that was, you know, very much at the top of our list to observe and report how things are happening to facility dialogue with the rebel groups. And then also, of course, there are questions about the black boxes. And one of the things, brooke, we were able to do over the past four days, which were frankly happy with is we facilitated the access of three or four aviation experts from the ukrainian side. So they have been combing over the fuselage and the debris and trying to find clues as to what happened. Nothing here happens quickly. It all takes time. But, you know, we feel quite a bit of progress is made, given the circumstances and given that this is happening in the middle of a conflict zone. I cannot imagine the job you and your group have undertaken, and the thought of going through evidence. Final question to you, because of course, there have been allegations of evidence tampering and concealing objects in the scene. It was the ukrainian president who even said there were reports of bodies and wallets being looted for credit cards. Have you yourself seen any of this with your own eyes . Of course we get asked that a lot. What we did observe today, and we have reported already to our 57 participating countries, we have observed that personal belongings, piles of luggage have been moved. We were told today by the rebels they have basically agreed to collect everything and put it in a big container and have it shipped. And we also have observed and reported that parts of the fuselage seem to have been cut in some places. Now, whether thats to help the body recovery or whether thats to look into things, we dont know. We are not there at nighttime. So we cant observe what happens when were not there. So its a very tricky situation. And dont forget, brooke, that this is an area that spreads over about 10 kilometers. There are about eight different impact sites. Its very, very difficult to monitor. And you know, there are others who are far better place than we are to, you know, look for those and analyze things. You have a lot of work ahead of you, and we wish you the best, given the almost unprecedented circumstances. Michael, thank you so much. Osce. Thank you. Just ahead here on cnn, if u. S.

A Significant Development here in the downing of malaysia air flight 17. Malaysias Prime Minister announcing a short time ago that prorussian rebels seen right here, you see what weve spotlighted for you, this orange piece of machinery. This is believed to be one of the planes black boxes from the crash site. And were learning they will now hand over these black boxes to a Malaysian Team for examination. Lets bring in security analyst, bob baer, former cia operative. And bob baer, is it surprising to you that the rebels are even giving up the black boxes and even, what, four days after the plane was shot down . Brooke, obviously they should have given it up the first day or looked a lot better. What the russians are doing and the ukrainian dissidents is covering their hand. They thought they could get away with this, blame on the ukraine. They obviously cant now. The preponderance of evidence is the dissidents shot it down, and possibly the russians. What we have to keep in mind is what has been occurring in the ukraine over the last month, and that is that the ukrainian rebels have been losing and putin has decided this couldnt happen. And thats why he rushed weapons across the border with crews that werent trained in incomplete Weapons Systems. And this is how we got this tragedy. And i think now putin realizes that things are going very bad for him, and hes got to give up the black box. And what evidence is left. So malaysia will ultimately have that black box in their hands. The question is, was it tampered with, will that hurt at all their investigation. It seems to me, talking to the bevy of, you know, aviation experts, it will theyll still be able to figure out by putting the pieces of the plane together. My next question is the overamping proof, bob, of the who did this. Do you think its already disappearing from the site, especially at night when osce and these other groups arent there monitoring, or do you think it is already gone . Oh, i think its probably gone. Theres probably missile fragments embedded in the wreckage, russian Intelligence Officers and ukrainian dissidents pulled the fragments out so the missile cant be identified. Thats an assumption on my part. But i think the main evidence is probably gone. The black box, an expert would have to tell you what you would get out of that, but not as much as actually identifying the as i say sill. So im sure youve seen this, and i want your reaction, because russia on the other side, their counter is this. They are claiming of course we know putin has been blaming kiev for what happened in the eastern part of the country and the hostilities there. But russia also claiming it it was a ukraine war plane that flew close to the boeing 777 right before it crashed. Your reaction to that. Probrooke, i think thats nonsense. If there had been a plane in the vicinity in that one and fired by a missile, it would have been picked up by all sorts of radar, adjoining countries. There would have been evidence of this. I think thats just its just a lie, fabricated. And even the plane would have called it in if they had seen this thing. No, i just dont buy that. I think this administration has presented the best evidence, and i think its very good. Most of from overhead, taking pictures coming across the border. Firing the missile and then returning. Its amazing how good this intelligence is. And i dont see the Obama Administration making this case unless the intelligence was very good. Final question, just quickly. Whats the biggest piece of the puzzle missing for you in all of this . Well, i think is the fact the russian soldiers crossed the border and another invasion like the crimea and helping the ukrainian rebels. I think putin is in a lot of trouble. I think more sanctions are on the way. And hes going to have to come to terms with the truth. Sooner rather than later. Bob baer. As always, thank you. And if all signs point to russia to his point, having some responsibility, maybe all of, for this attack on malaysia air flight 17, the big question for the white house and congress is what to do about it. Is it time to stand up to russias president once and for all . Would additional sanctions even work . Then a network of tunnels burrowed under the border. A devious system that militants can use to carry out attacks against israel. Cnn went down into the earth to see how they work and why theyre such a threat. Norfolk southern whats your function .

We are following breaking developments this hour from the middle east, herel as well. Israels Defense Forces say seven Israeli Soldiers have been killed today inside and along the border with gaza. 25 soldiers and 2 Israeli Citizens have died since the Israeli Offensive began. On the other side, more than 500 palestinians, many of them civilians, have been killed. In washington, president obama says he has instructed secretary of state john kerry, who by the way, is in egypt, to push for an end to all this fighting. And that is why it now has to be our focus and the focus of the International Community to bring about a ceasefire that ends the fighting, and that can stop the deaths of innocent civilians. Both in gaza and in israel. Israels focus has turned to locating and destroying this Extensive Network of underground tunnels in gaza and specifically leading from egypt into gaza. The Israeli Military has released this video that youre looking at here, shows what appears to be these gunmen emerging from a tunnel, opening fire on israeli troops. A spokesperson for israels Prime Minister told wolf blitzer that the tunnels are being used to launch assaults. It has to be just this morning. Two squads of Hamas Terrorists came through tunnels, entered israel in the south, they tried to attack two different civilians, farmers trying to conduct their daily lives. It shows who hamas is, an extremist, deadly terrorist organization. And the worst of all, the people of gaza are suffering because of hamas. They didnt want this war, wolf. Cnns Paula Hancocks joins me from new york. We have seen this video of you inside these tunnels from just a couple of years ago, these multipurpose tunnels. Tell me about them. What did you see . Reporter well, brooke, there are a couple different tunnels. Basically those from gaza into israel, which are being used by hamas militants to launch attacks. And then the other tuns which i went into on a number of occasions which go from gaza into egypt. These are the smuggling tunnels basically used to bring in food, bring in gas, livestock, anything else that the gazans need. And also, according to israel, are used to resupply hamas. That is how they get their weapons into gaza within this blockade. Certainly was interesting seeing these tunnels. They very basic. The ground is clay and sand, not particularly conducive to these tunnels. A number of collapses. We have seen over the years israel bombing them quite significant
