Bangladeshi Officials Say it was carried out by home grown militants. In turkey, 16 more suspects in last weeks deadly atk on the istanbul airport are appearing before a judge. Separately, police have arrested two suspected isis militants at the istanbul airport this weekend. Ben wedeman is in bag dag. We have cnn correspondent alexandra field and nimr el bagra in istanbul. Ben, what are you learning . Reporter very little in terms of exactly what happened. It appears it was a refrigerator truck that went off just before midnight saturday night. What is notable about this bombing is that it seems to have created a wave of flames that went out to both sides of the street causing huge damage to this commercial area, killing at this point where we know as many as 215. Its expected that the death toll will rise as they dig deeper and deeper into the ashes and the rubble at the scene. According to the iraqi police, of the bodies recovered, 81 are simply charred beyond all recognition. They are going to have to do dna tests. This means that hundreds, thousands perhaps of people in baghdad have no information about loved ones that seem to have disappeared off the face of the earth saturday night. We were at the scene of the blast for about five hours. There, for instance, i met a woman who told me that for more than 24 hours, she has been going from one baghdad hospital to another, from one morgue to another searching for her 29yearold son who was clothing shopping at one of those malls on saturday night. She said, all the bodies she saw simply were beyond recognition. Another man was sifting through the ashes and the rubble and found his brothers prayer beads. He broke into tears sobbing uncontrollably and had to call his mother to tell her that her son had died in the blast. Many seeking for information but there is very little available. Heartbreaking stories that you are telling there, ben. Thank you for that report. I want to go now to alexandra field in dhaka, bangladesh. You are learning more information about one of the attackers, right . Reporter thats right. We have heard from authorities that all of the attackers were bangladeshi. They have been identified as being 18 to their mid20s and identified as being affluent or upper middle class, welleducated. I spoke to the father of the youngest attacker. His father says he had not seen his son since february. His son has suddenly disappeared from the house and gone it Law Enforcement authorities for help looking for the son. The father has become increasingly concerned that his son had perhaps taken up with an islamic group. Previously, he had never shown signs of radicalization or religious extremism. At 18, he believed his son was immature and impressionable. He says his son was full of humanity, a kind and loving person, thats why he cannot swear the child that he knew with the man who acted out that hideous massacre with a gang of assailants storming into a cafe killing 20 people inside, killing two other Police Officers who tried to stop the hostage situation, freeing 13 people in the end. The father says that he cannot bring himself to go identify his sons remains, because he just cannot believe his son would carry out an act like this. Isis has claimed responsibility for the attacks. U. S. Intelligence officials are also looking at isis as the likely perpetrators of this attack. However, officials here in bangladesh say they are focused on whether it was carried out by a domestic terror network. Brianna. Alexandra, thank you. Nimra, we are learning that turkey is striking isis targets. Can you update us on that development . Reporter yes, this is through a news agency. They said, for every one of us they kill, we will kill ten of them. Any say they have hit 68 isis targets and confirmed the death of 14 isis militants. The turkish authorities believe these targets and militants were actively involved in preparing a new strike against turkey. Given the week we have just seen with the attacks not just here in turkey but in bangladesh and baghdad, as they continue to be on high alert, they appear believe isis when their spokesman say that this isnt over. More attacks are being prepared, brianna. Nima, there seems to be this pattern that we are seeing, not just in istanbul but also in bangladesh where it seems isis is targeting, really, muslim targets but secular governments. It seems to be that they are sending a message. Absolutely. Turkeys is a very valued member of the u. S. Led coalition in syria. It is also about trying to get as many impact for your strikes as possible. Turkey with its multibillion dollar tourism industry. A number of countries, european and American Travel agencies specifically target turkey, extraordinary cultural heritage. Looking at paris, on high alert, brussels, or berlin, it is much easier to resonate by hitting somewhere like bangladesh or istanbul where you can appear to be targeting western targets by proxy. The other interesting shift in strategy is this use of home grown terror networks, not only to support the foreign fighters as we have seen but to operate much more easily under the radar as we saw in bangladesh. It gives them this exponential effect. Nima elgagir, these attempted attacks dont stop there. We want to warn you the video you are about to see is disturbing. Today, they revealed that the two gunmen that carried out the june 8th attack at a telaviv market were inspired by isis. Four israelis died, 16 were wounded. In saudi arabia a suicide pommer killed only himself after detonating an explosive near the u. S. Consulate in jeddah early this morning. Police had been suspicious of the man who appeared to be roaming around a parking lot of a hospital. We have a panel, Nic Robertson with us in london, cnn military analyst, Lieutenant Colonel rick francona, joining us from oregon and Cnn National Security analyst, juliette kayyam. What can you tell us . This happened in the city of latif. We are just learning the details. The suicide bomber was approaching a shia mosque in this town east where katif is. It is a predominantly shia area. It is not unusual for isis to target. They have done several times in saudi arabia before, target shia mosques. We dont know who the attacker was, who claims responsibility for this. At the moment, details we have is a suicide bomber was approaching the mosque, a shia mosque in the town of katif, in east of saudi arabia. He wasnt allowed but was stopped somehow from getting close. His explosive vest detonated. Thats what we understand. We are also told there were no casualties. We have been learning some other details. There may have been another attacker involved in that particular attack. Also, from the same sources, this needs to be checked and run down. I will keep the details brief. From the same sources, we are getting information of another suicide bombing attack or attempt in another city in saudi arabia. The one in katif, no casualties but an attempt to kill shia followers as they were at a mosque. Juliette, i want you to listen to comments from colonel christopher garver. Here is what he said. As we take terrain away from them and we defeat them, they have not won a battle in the last seven months ever since the fall of ramadi last year. They have not won a battle. They have only lost ground. They are trying to remain relevant on the global stage and trying to show that as they attract crazies and sickos from across the globe, they are trying to show that we are still a viable threat. Juliette, speak to that. Yes, we know that isis has lost 25 30 of its territory it held in iraq and syria. Does it really matter when we are seeing these attacks on soft targets increase . It absolutely does matter. What will make isis thrive is their capacity to hold on to geography. The fact that they are failing is good news even though we have all this bad news. They have limited space to train and have recruits quom to and get money. While the geographic losses are good news. Obviously, the secondary impact, which is there are a lot of men who are now leaving the geography of iraq or syria or getting inspired by whats happening with isis and launching attacks on soft targets. This is just not just but a second wave that wasnt anticipated, however, sort of scary it is right now given there is an attack every sort of 2436 hours. Colonel, talk about this attack in baghdad. Yesterday, the death toll we believed was 125. Then, this morning, it is up at 215. Talk to us about this neighborhood, the corada neighborhood. Korada is a large shia neighborhood in the center of baghdad. For them to get into the city that far undetected and to mount this kind of attack really says something about the state of Iraqi Security and the iraqi people are very, very upset with their government for not being able to stop these attacks. This is a huge casualty. A very crowded area. The bomb went off in a shopping area. This wall of flame went out. We dont know how many people are still missing or buried in the rubble. The devastation in a truck bomb is going to cause a lot of problems for the government. The citizens of baghdad are very concerned with their own security and starting to take it out on the government. Nic, i assume you have been to this neighborhood . I have. They are trying to create a massive sectarian divide, the west is sunni. If they can create such a sectarian rift and make it impossible for a shiadominated government, because of the an mossity of shias toward sunnis, if they can make it impossible for a shialed government to control and rule, over time, their as as per racial would be to take it back. They look way beyond where we are at right now. Nick robinson, juliettekayyem and nick francona, thanks for all people here americans get ready to celebrate the fourth of july.

New information in the central park ex cloplosion that severely injured a teenager. 18yearold connor golden had his leg nearly blown off as he and two friends jumped off of a rock in central park. Security is being heavily stepped up after several terror attacks in the last week. Deborah feyerick takes a look at what precautions are being taken in new york and beyond. Reporter after a series of deadly attacks overseas, u. S. Counter terror officials heightening security measures at socalled soft targets across the country including the july fourth fireworks displays tonight. In the nations capital, much of the dramatic increase in security will be hidden. We do have technology that folks will not see. Reporter the biggest Fireworks Show in america along new york citys east river with an estimated 3 million spectators has the police on high alert. You will see a very significantly enhanced Police Presence in the city. Reporter out on the water, officials patrolling the harbors in manhattan and controlling security docks along the macys fire barges. We will have ex enceptional Police Presence to keep everybody safe. Reporter deploying 500 plus highly trained, highly armed officers ready to prevent terror. The first fourth of july the Critical Response team will be out in full force. That sends a powerful message to anyone that might try and disrupt. Tensions already high. It sounded like a cannon after a small explosion in central park left a tourists foot mangled. His foot is all but detached. His friends claim he was walking down the rocks and stepped on something. That something believed to be an experiment with fireworks or a homemade explosive set off after a young tourist accidentally stepped on it according to the nypd. We believe this could have been put here as some sort of experiment. Deborah feyerick joining me live along new yorks east river. This is a tragedy for a young 18yearold man. We have a statement from the university connor golden attends. Reporter we do. They just named it and connor golden underwent surgery at bellview hospital. He was attended the university of miami. They did release a statement. It says the university of miamis thoughts and prayers are with connor golden as he recovers from this horrific accident that took place in central park sunday morning. We will provide connor and his family with complete support through his recovery and rehabilitation. Police are saying that they dont believe that this was terror related. This device was left there with no intent to commit harm. When he jumped from a rock on to a plastic bag, it somehow exploded. They dont think it was terror related but it scared a lot of people and certainly the police who are ready and on alert and on edge right now. He has some challenges ahead. We are thinking of him and his family as they go through this. Security is expected to be extremely tight. Despite the events, president obama is staying informed and being briefed on all of this. Michelle cos s Michelle Kosinski is following this. What is the white house monitor sng. They are going to pay close attention to whats happening around the world as that relates to a potential risk here in the u. S. We know the president was briefed on bangladesh as it happened. He wanted to be kept informed through the weekend as developments happen. We know that the white house is watching. They put out a statement that says things like this only strengthen the u. S. s resolve to support the government. As horrific as this string of attack has been, the one reassurance is what we hear from u. S. Officials over and over again. Now, there is no specific credible threat within the u. S. What they want to be careful of, though, are the possibility of copy cap attacks. Things that have been planned under the radar, the type of attack that keeps them up at night, the most difficult to prevent. It is something that we hear repeated often. Right now, no specific threat targeting any known targets here in the u. S. What is the president up to today on this july fourth . We dont hear from the white house. There is no daily briefing, Nothing Official as relates to the press. Every year, they have a barbecue. There is musical performances here at the white house. Thats going to get underway. Here, it feels like the sky is going to open up every second. That has been changed significantly. There is supposed to be some 6,000 people on the south lawn. We have been told it has been whittled down to 500 people. The whole thing has to move inside the white house. It is malia obamas 18th br birthday today. We expect the president will have some time with his family. The president will spend some time with those families as well as his own before he heads out on some travel. Tomorrow, he will be on the campaign trail with Hillary Clinton and after that, warsaw with the nato summit. A long speight of travel heading up to the president after he spends a little time celebrating the fourth of july. Brianna . A big week for him after a family celebration. Michelle kosinski, thank you so much. It is a holiday. Donald trump hasnt taken a vacation from twitter. He is talking about his meeting with potential vicepresident ial candidates giving a shoutout to republican colleagues and defending his weekend tweet featuring a sixpointed star.

Together, were building a better california. We just got some new video in of the attack in saudi arabia outside of a mosque in ka teef. You can see a vehicle is on fire. It is evening time there. You cant it is somewhat difficult to see. There is a vehicle there on fire as this camera makes a turn in the corner there. I want to bring in Cnn International diplomatic editor, Nic Robertson. Nic, this is the first look we are getting at this. What are you learning about whats going on inside saudi arabia . I think we have a lot more details to get ahold of now to ascertain precisely what happened. It was late afternoon. It appeared people going to the mosque at the end of the day, nightfall just as they would be breaking their fast. It is getting to the holiest part of ramadan right now, the next day or so is the big festival. This is a time for muslims of absolute joyousness of coming together with families, buying presents for everybody. A huge deal. There would have been a lot of people at any of the mosques in that area. Not quite clear from the video precisely what one was being targeted. The source i spoke to said that the suicide bomber trying to get to this mosque wasnt able to reach it, blew himself up. He wasnt able to explain why the suicide bomber couldnt reach the mosque, blew himself up. Th
