And good morning, america. It has happened again. The joy of normal life becomes a nightmare in seconds. That was the scene in nice, france, last night. Those thousands that gathered to celebrate the National Holiday after the fireworks shots rang out then this truck mows down the crowd stretched out for more than a mile that was it right there. You saw the people running. You saw the horror leaving a trail of unspeakable carnage. The images are horrific. The suspect was shot and killed on the scene. Officials are now searching for accomplices. At least 4 people were killed including two americans and at least 50 others were injured. Frances state of emergency now extended three months. It was supposed to end on july 26th. This is the fifth terrorist attack in france since january of 2015. State of emergency continues there. We have Team Coverage here and overseas. Starting with abcs Alex Marquardt on the scene in nice, good morning, alex. Reporter good morning, george. This attacker could not have struck at a happier or busier time. This is where it happened. You can see this entire waterfront has been shut down. This is called la promenade des anglais and the beaches are closed as france tries to come to terms with this latest horror at 10 30 p. M. Local time as thousands took to the famous streets to take in a now just fireworks celebration commemorating frances National Holiday a white truck emerged. This video capturing it moving slowly at first then quickly accelerating aiming directly into the densely packed crowd killing and maiming scores of men, women and children. Screams of panic and terror echoing throughout this popular coastal city. You could see blood and bodies everywhere. Reporter the Truck Driving a little over a mile mowing down dozens like a bowling ball as hundreds ran trying to escape. They were all screaming and everyone was running in every direction. Seconds later this giant white van came bolting down this road at was just taking out people left, right and center. At this point we began to run because everyone was frantically running because we had no idea what was actually happening. Reporter panic spreading throughout the crowd as hundreds grabbed loved ones and ran, some people jumping into the sea to escape. We were just turning down alleys and kind of looking for somewhere that might be safe. We just assumed there were fireworks still going off but then really shortly after that i saw people running and, you know, we didnt at this point have any idea what we were running from. Reporter security on the scene fired at the truck riddling its cab and windshield with bullets finally stopping the bloody rampage and killing the gunman. [ speaking a Foreign Language ] reporter Law Enforcement on the scene described the truck as full of weapons and grenades. Frances president Francois Hollande telling his country the horror has once again hit and that france is under the threat of islamic extremism. Among the at least 84 dead were two americans, Sean Copeland and his 11yearold brodie, the two austin, texas, residents were in europe on a Family Vacation which began in spain, a Family Member put out a statement saying losing a loved one is hard no matter the circumstances, but losing a loved one in such a tragic and unexpected way is unbearable. A lawmaker told french radio there was someone on the street that jumped on to the truck to try to stop it and that was the moment that the police were able to shoot and kill the driver. And, george, just a short time ago the state department did confirm the deaths of that american father and son. They have offered their help and condolences. George. We offer those condolences as well. Thank you, alex. Brodie copelands Baseball Team posted this photo on facebook. They showed brodie in the French Riviera and they ask for prayers for the copeland family. We are joined now by another american on the scene, Inga Romanoff in nice this morning. Inga, thank you for joining us. I know you were on that promenade when this all broke out. Tell us what happened. Thank you for having me. I was right on the promenade on the side where the truck was rolling through the crowd. At the moment when it was happening. And how far away were you when it start to come through the crowd . What kind of notice did you have . What kind of alert . It happened very quickly. It was literally split seconds. We were just heard the gunshots. The first gunshots and i started running. I looked back and i saw the truck going through the people right in a place where i was standing. Just seconds. So it was coming right towards you. About how fast was it going . He was actually accelerating, i think, or at least it seemed that way. He was definitely going over 60 miles an hour. It seemed very fast. And you actually had to jump out of the way . I dont think people had any time to jump out of the way. It was a very large crowd. It was right after the fireworks, everybody was still there and there was not enough space to even give each other way to run out of the way from the truck. I think some people probably could do that if they were on the fringe but i dont think anyone had much time to run away. If you are further down on the promenade where i was, maybe because we had bash we heard the gunshots so we had a little more notice but the people in the beginning of the promenade had no chance. So at the beginning of the promenade, youre talking about an avenue where people are 10, 20 across completely packed in . You broke up for a second. Would you mind repeating your last phrase. The scene on the promenade especially at the beginning is 10, 20 people across. Verily densely packed. They had no chance, no way to get out of the way . Actually i cannot hear you right now, not at this moment. Im going to try one more time, inga. The question the question, how densely packed were these people at the top of the promenade . You were asking me how many people were around me . Yes, just try to describe the scene. Let me tell you within split seconds of hearing the gunshots i started running and the entire place seemed like a complete chaos. People were running in different directions, there were people all the way around me. There was so many of us that there was ill tell you im running and there was a lady right next to me. She stumbled and fell on the ground and nobody was even helping her. People kept running over her and i was trying to pick her up so she could also run. It was complete chaos all the way around and i dont think people knew in which direction to run. It was not quite clear where it was safe. I think not maybe everyone saw the truck. I dont know but it was a little bit disorienting. I can only imagine how disorienting it was. How did you finally know you were safe . Where did you end up . Yeah, i cant i think first of all when i was on the other side of the road, astin have as i heard the gunshots i ran across away from the crowd and felt safer but still looking around to understand where the gunshots came from because i saw the truck pass by but wasnt sure it was over. To me it was immediately apparent it was an attack, not an accident and i actually stayed right next to the scene. I was in a hotel where i could see the entire scene from and i just ran to the hotel as soon as i was in the hotel i felt safe. Were glad youre safe this morning. Inga, thank you for sharing your story with us. And now, of course, the focus on the investigation. We know that french investigators desperately trying to determine who was behind this attack and whether isis was involved or not. French president hollande saying france as a whole is threatened by islamist terrorism and abcs chief investigative correspondent brian ross is here with the very latest. So, brian, what can you tell us about the suspect . Who may have been behind this . Good morning, amy. As of this hour theres been no claim of responsibility for what happened in nice but online followers of isis have been celebrating the deadly attack. French media this morning are identifying the suspect as a 31yearold frenchtunisian w whose apartment is being searched at this hour. U. S. Officials this morning say isis is certainly the leading candidate given their huge ranks of french recruits and repeated calls for just such a vehicle attack. French recruits are estimated to be some 1700 french citizens believed to have gone to iraq and syria to join Terror Networks mostly isis, many have been killed and others have returned to france with numbers so large french authorities have been unable to keep an eye on so many suspects and, again and again isis sent messages to its followers about using vehicles to attack, quote, according to one spokesman, if you are not able to find an ied or a bullet, then single out the disbelieving american, frenchman or any of their allies, smash his head with a rock or slaughter him with a knife or run him over with your car and on. Simple but unsophisticated weapons. Americans, frenchmen. What are the immr. I indicati implications here. The u. S. Is a top priority target which offered american recruits similar encouragements. Counter terrorism officials are looking at closely the tempo of the attacks in the west. It was just two weeks ago that an isis directed attack was carried out at the airport at istanbul, turkey, and two weeks before that it was the isis inspired attack at the nightclub in orlando, florida. So far more than 400 people have now been killed by isis attacks on western targets, not including nice and, of course, thousands, thousands more in syria and iraq, slaughtered by isis, amy. All right, brian, thank you. Now to the white house. Jon karl is there. Our chief white house correspondent. Of course, jon karl, as soon as this happened president obama has been working so closely with france on this. He was briefed almost immediately after the attack and directed the white house to offer any assistance to french authorities with that investigation. The president later issued a statement saying, quote, on behalf of the american people, i condemn in the strongest terms what appears to be a horrific terrorist attack in nice, france. We stand in solidarity and partnership with france, our oldest ally as they respond to and recover from this attack. Secretary of state john kerry was actually in paris just hours before the attack attending a bastille day parade with french authorities and directed the state department to try to account for all americans in nice urging them to contact the consulate and, of course, to directly reach out to their families and friends. Ing okay, thanks very much. Lets turn to Martha Raddatz who has the very latest on the war on terror and where things stand in the fight specifically against isis. Good morning, martha. What can you tell us . Reporter good morning, amy. As you know, the u. S. And coalition have been pounding syria, pounding iraq. Were about to send more than 500 more troops into iraq to try to retake mosul, the iraqis have retaken fallujah and retaken ramadi but as they squeeze the isis fighters in iraq, in syria, these attacks go beyond the border and thats the real problem here. They have to keep up with the intelligence. They have to find out who is returning to france, who is returning to these other countries and theres a real strain on Law Enforcement and intelligence. Amy. All right, Martha Raddatz with the latest. Thank you. Of course, amy, those deadly attacks overseas are raising Big Questions about safety on soft targets at home. Pierre thomas tracks Homeland Security and, pierre, concerns here especially high with both political conventions coming up. Yes, george, Law Enforcement has identified no specific threat in connection with those conventions but i can tell you theres deep concern just because of all the pace that were seeing of the just yesterday fbi director and Homeland Security secretary jeh johnson was expressing worry about the potential things could get out of hand mainly because of groups with polarizing views that may descend on each convention. My sources tell moo he that leading into the conventions, that this is perhaps the most volatile and complicated security picture in recent memory. It comes against the backdrop as weve talked about so many time, pierre, with new warnings and alerts from isis to all of their followers, just attack whoever you can, wherever you can. Reporter the short answer is that theres real risk. We saw San Bernardino last december and only about a month ago as brian mentioned the orlando massacre when a madman inspired by isis killed 49 people and wounded another 53. I can tell you ive been talking to security sources last night and this morning and theyre locked in on whats happening in france in part because as we said, were only days away from the start of those conventions where there will be very large crowds, george. Pierre thomas, thanks. Affecting the entire race for the white house. Donald trump set to name his running mate this morning, sources telling abc news hes asked indiana governor mike pence but now postponed that announcement and tom llamas is at trump tower with the latest. Reporter amy, good morning to you. Campaign sources tell me that donald trump will announce this morning that he is rescheduled his joint appearance with his running mate possibly in a tweet and this will launch the new team and end what has been a vp Selection Process like we have never seen. Sources maintain to abc news that indiana governor mike pence is the pick. This morning, donald trump not ready to show his cards. Republican sources told abc news trump offered the job to indiana governor mike pence and pence boarded a plane, flew to new york thinking he had accepted. How do you feel . Reporter but as we caught up with pence at a Manhattan Hotel trump said this in an interview. Mike has done a great job as governor of indiana. You look at the numbers and its been great, you know. Hes been done a fantastic job but i havent made a finalfinal decision. Reporter trump canceling his big News Conference to announce his running mate citing the tragedy in france. And out of respect for this horrific situation, i just think it was inappropriate to have the News Conference tomorrow. Reporter though trump could change his mind. All signs still point to pence. The firstterm governor ser a 57yearold establishment republican who is a born again christian. He served as a member of the u. S. House of representatives for more than a decade and is a former radio and Television Talk show host. In apparently selecting pence, trump chose someone who is very untrump and could be a rocky honeymoon ahead. I do strongly disagree with the call that would ban muslims from this country. I found it both offensive and n unconstituti unconstitutional. Reporter pence has had major disagreements with trump and this week pence seemed to dodge a direct question if he supports trumps plan to build a wall along the southern border. As president Ronald Reagan said a nation without borderers is mott a nation. Reporter pence told me he could still work with trump even though he doesnt agree with him on everything. How do you share that ticket if you have a fundamental disagreement with him on the muslim ban. Look, i served in congress for 12 years. Ive been a governor for 3 1 2 years. I havent agreed with every one of my republican colleagues or democrat colleagues on every issue but im supporting donald trump because we need change in this country. Reporter now, as for the convention, it had been reported by others that tim tebow was going to speak at the Rnc Convention but tebow has posted a video on instagram saying he will not appear at the Rnc Convention. He also said this, lets forget our quarrels and our differences and come together on one nation under god. Amy and george. Okay. Thats the message of tim tebow and i think mike pence likely to be well received by that convention. Now lets go over to ginger for the weather. Did you guys see this . The severe thunderstorm that rolled through new york city in the afternoon hours and you probably didnt see it from this perspective. That is a timelapses fortunately not as much you much damage here. Look what happened with the severe thunderstorms, little rock arkansas trees down in homes and cars. 125,000 customers without power. Thats a problem, it gets hot you dont have airconditioning and nowhere to cool off. Today we have potential for strong winds along 70 in kansas and oklahoma.
