We will, we will rock you flying at half staff, honoring those that were killed in the tunisia. This weekend, fears of an isis inspired attack have authorities on edge. And greeces financial if you tour hangs in the balance. We hear from greeks about what they think about the debt crisis. And the number of shark attacks along the eastern u. S. Has beach goers a little nerved up. One survivor shares his story. I would be nervous to get into that water. I know. Welcome to our viewers here in the United States and around the world. Im george howell. And im natalie allen. And youre watching cnn newsroom. It is 8 00 a. M. In the United Kingdom where they are remembering what happened at beach resort in tunisia. Flags have been lowered to half staff including at bumming ham Buckingham Palace in england. Bodies will be repatriated today. Phil black is with us. Phil good to have you with us. Whats the latest on the investigation at this point . Reporter george according to the authorities here there are eight people in custody, of which one is a well. But we know they are still looking for more. And the interior ministry here has posted an image and details of another suspect that they are looking for specifically third time theyve done it this week. In this case 29yearold man who they believe played a role not only in the resort attack a week ago. But also in the museum attack here in the capital in march which killed 22 people. The authorities are clearly working on a theory that both of these attacks, these events, were linked. And it is believed that the gunman in each massacre trained together across the border in neighboring libya. That increasingly lawless country where groups such as isis are getting a stronger foot hold day by day. We spoke it a prosecutor here yesterday who said they are being very cautious in the information they are releasing publicly because they believe they are in the process of disrupting a wider Terror Network that they have uncovered through the course of this investigation. And reluctant to make too much information known for fear of tipping off those who they believe are members and allowing them to escape. Phil around the country, tunisia is certainly beefing up security as we have been reporting. But i with like to know what sort of differences have you seen any differences that point . It is not a striking difference i dont think you would say. One week from the attack security has been lifted yes. Certainly in beaches and areas popular with tourists. It is more noticeable. But it is not blanket coverage. You see people patrolling. You see police and Security Forces own bike, on foot moving around by car. This is still a place where freedom of movement is still, well still very open. And there is no sense that the security are really lated in coverage of any particular area. But i should say a lot of the tourists we have spoken to dont necessarily want that. They dont believe that would be appropriate. They understand what we are talking about here and it speaks to the challenge really. A very wide area of sand and sea and large towns and so forth. The idea of cracking down and really securing this in an absolute sense, it is a real challenge. It would take extraordinary amount of work and would certainly change the atmosphere of this place dramatically. Senior National Correspondent phil black live in tunisia. Thank you so much. We will stay in touch with you as this investigation continues. Given what happened in tunisia, members of Britains Parliament say they are willing to discuss stepping up their fight against isis inside syria. Where they have not been. Theyve been inside iraq. We know that isil is organized and directed from northern syria. Thats why prime ministers said during the debate last september on taking military action in iraq that and i quote, there is a strong case for us to do more in syria. Well back in tunisia, the city has become a pipeline for radicalizing young men driving them into the arms of isis. Cnn checks into that story. The mountains on tunisias boreder with algeria, for months now the government launched campaigns aimed at rooting out the terror camps hiding in these barron slopes. This operation, like all those before it, failed. On the foot hills is the roadses to the town. It was in these poor streets that spark of the tunisia resolution caught flame, hoping for a better life that never came. We have nothing, nothing. But Something Else did. This young man spent two months in a tunisian jail. He said he was charged with being a terrorist. Something he denies. We are not revealing his identity for his safety and the safety of his family. They thought me how to pray. We used to pray together. Then one day the police raided the mosque. I stopped going to the mosque. I even stopped praying. But they werent done with him. Earlier this year the threats began arriving over facebook. It was the men from the mosque. He says they told him they knew where he lived. His sin, he hadnt joined him. A man describing himself as an isis commander told him, weve gat got a job for you. I knew it was either be killed or be a killer. It is believed that tunisian fighters were unmatched by any other national enate authorities identifying a very simple pipeline of recruits. Many of the mothers we meet here tell us they lost sons to jihady ideology. Even missing, jailed, or dead. A son prayed in the same neighbor mosque. One day last year, he disappeared. After ten month is we were watching the news and we heard them say they had been fighting in the mountains. As we sat there, we heard them announcing his name. And the group with him was killed in the mountains. I heard the interior minister announce it. In spite of the influence of foreign fighters the tunisia Battle Ground are increasingly here at home. Where attacks on soft western targets grab headlines around the world. Recruitment, were told is in the mosques. Brazen and in person. He said to me you, i know your mother your father, i can take your brother, your mother. I can throw a bomb over your wall. The terror caps arent just a few of the training grounds in the mountains of northwestern tunisia. It is a contagan felt far across the borders. The man known as suicide bombers has been killed m a Coalition Air strike in syria. U. S. Defense Department Officials say he was responsible for getting people and materials into iraq and syria and help to recruit fighters. We spoke with cnn military analyst retired colonel Rick Francona to get his thoughts a short while ago. Any time you kill one of these leaders, its a good thing. But what happens is they are easily replaced. The good thing is, when they are replaced replaced they are normally replaced with shn who doesnt quite have the skill set or they would have been in charge. So you constantly whittle away the organizations until haveleadership. It worked well forness afghanistan and iraq. I think that will continue to work for us. These are small steps. What we need to do is find out where the leadership is and good after them with a vengeance. And i think it is incumbent upon us to deal isis a blow a real military defeat. Because as long as they appear to be successful on the battlefield, their recruitment efforts are going through the roof. If you look at what happened last week their recruitment is up because of the success they had in kuwait. In tunisia. And in france. That is profile indicates he was freed from prison in 2013 during an isis raid. Concern among u. S. Security officials is growing over potential terror threats against the United States during the upcoming july 4 holiday. The u. S. Air force cancelled a big fireworks and air show at a base in england. On thursday there was a lock down at ws navy yard. Jim sciutto has been working his sources and has more from washington. George the alert at the navy yard here in washington started with an employee who heard noises and thought it might be gunfire but it turned out to be construction noises. This is across the country. Concerns of attacks by isis supporters. Tied to the july fourth weekend added here was the fact that it was a military facility there on a higher level of alert and it is a military facility that two years ago had another shooting event. But it shows you the difficulty of these decisions as they are happening. It is hard it keep on alert for all these things in so many places and we saw this repeated overseas. U. S. Military base on a British Military base on the north ef england. There the base commander is making a decision that the risks of holding a july 4th celebration outwayed the rewards of doing so. Were told by the u. S. Military that this was a base decision by base committee there. It is not a european wide decision to cancel july 4th celebrations. But it is a threat level with very nonspecific threats. Officials say their concern is this broad call by isis to supporters around the world to time their attacks to the muslim holy month of ramadan. But heightened concern in the u. S. About other holidays. As it happens, july fourth falling within the holy month of ramadan. Great concern here. Difficulty responding to these threats. But it raily is a measure of that nervousness. George . That is jim sciutto reporting there. Authorities in nigeria are looking into a series of attacks that killed nearly 150 people. It looks like boko haram struck again. How is the government the new government there, dealing with what has happened . Natalie, thats a good question. This is a critical time for the new administration. And the president during election and now pledging to take the fight to boeko what ram p. M. Even in the north, there were no checkpoints there. Police were manning a few that still were around. But one could take soldiers off the streets, he wants them out of boko haram. And there is optimism that wasnt the case in attacks continue despite what is a multinational coalition. You see attacks on visitors where hundreds of defensive civilians have been targeted and killed. Natalie . Yes, they just continue their rampage, it seems, no matter what. Thank you. . George . Colombias defense minister said a series of explosions are without question terrorism. The explosions happened outside the offices after Pension Fund Management company. At least eight people were wounded. Someone called it say they left a suitcase full of closes. The government is offering a 38,000 reward for anyone with information. About who basically called in those explosions. There is an outpouring of grief after a prominent football coach was murdered.

Major rallies. People are in line to withdraw money. There are strict limits on how much money people can withdraw from cash machines. Greeces finance minister has harsh words for european creditors. Thats right. He spoke with richard quest. Here is what he had to say. Think of what is going on in the last five months. As an investment into achieving an agreement that is mutually beneficial for everyone. Why is the Greek Economy so badly the last few months. Why are the barvegsbanksed closed . They are blackmailing the government. And were not going to do this. And the euro group says they are incompetence tent or inexperienced or maybe both. Richard the reason we were elected is because they failed misserably. They will go down in Global Economic history as the biggest failure ever. That is why im sitting in this office now. So perhaps all sides should take a step back and reconsider their own contribution to the last five years of this disaster and maybe they should take very seriously the very simple proposition that it is time to stop extending this crisis into the future. Richard quest. He puts the questions there. He does the job. There is a lot of uncertainty with all of this. So lets take a look new at how the world Financial Markets are react together latest news from greece. Mariae. Nina santos has more for us. How are they reacting on the latest trading session before greeces referendum . Reporter as you can see, there is nervousness. Tough talk from richard but equally tough from the finance minister of greece. And yet again a lot of this ramping up really hasnt helped these markets over the course of the last week or so. It is surprisingly resilient over the last two trading sessions when it seemed as they greece was willing it make compromise but as we knew there was always a little bit more to it than that. And this is why i want to show you the monthly pattern in germany. Key markets in france and germany, their leaders will have a huge say in what goes on if the euro group, which is the years of finance ministers finally agree to come to some kind of deal with greece over the next few days after that referendum. Look how the picture is. Each peak goes to show how people got very very optimistic that we might have a deal and then yet again things degenerated into the battle of wills, if you like. And so these markets, also i want to point out that single currency it itself with Angela Merkel stressing that europe is not in the same predicament as it was five years ago when greek got its original chunk of bail yut money bailout money. And the euro versus the dollar as you can see, currently holding up at the moment. If you are trading in dollars, it buys you about 90 euro cents. When it comes to the euro versus the dollar we are talking about a level of 1. 10 to 1. 11. It. All right and nina now the imf says greece will need even more money than people thought. And it is a number that is of course staggering. It is a number that is around 50 bill yop euros, almost twice as much natalie as the amount that the greeks originally requested when they made the surprise request over the last few days the third bailout chunk of money. Irrespective of the fact that the second bailout is actually now expired. And they have run out of money. The imf says guys you need more than that. Here is the caveat. Remember that greece defaulted in the imf payment of that 1. 5 billion earlier this week. The imf certainly will probably not let greece off the hook for that because it sets a very dangerous precedent. But the imf at the same time sending mixed signals here. Because the imf is saying we agree with part of the greek governments rhetoric that yes this country doesnt have a hope of paying back its mountain of debt. But it is unlikely many economists say that the imf will allow greece off the hook for its debt will rely on European Partners which is half billion of its own to try and find the money for that debt relief for greece. But again, referendum is the big thing this weekend for these markets. All right. And we will of course be watching it and covering it. Thanks you so much nina santos for us there in london. Thank you, nina. George . Even with the push from the government a push to vote no. Greeks remain divided. I am in europe. I want itto stay in europe. There is no decision within the european union. Im sure about this. Next time we will vote yes. Because we want to remain in the union. I think i would say no. Because im here and i cannot leave. Trying to play the future of gross in cards. We do not want to have our future played in cards. No. No no. I want to believe that we will go even in the last minute they will think of that and they will vote for a yes. Because the majority of the people believe in europe aepnd the eurozone. He hewe want the government to make the decision not the people. Only future for my country, for me my family my children grandchildren, is to cooperate with the other europeans and go ahead. The vote is very much divided there. But you know greeks have a very important decision to make. Yes, they do. Then who knows what happens after that. Youre watching cnn newsroom. We are learning more detail of exactly what went on in a new york prison before two inmates escaped. But this is not the enly prison in the u. S. To see its share of drama. Yes.
