Attack at a mall in minnesota. We have our coverage across the country. Lets begin with richard engel. He was in chelsea. Reporter i spoke to a witness even closer to the scene than i was. He said he heard a very loud explosion, immediately thought it was a bomb. His ears were ringing. He was inside his apartment. The window didnt break, but the mirrors fell to the ground. He wt glass everywhere, on both sides of this very busy intersection. He said that some of the broken windows were as high as on the fourth floor of nearby buildings. Whats unclear, however, is who did this or why. Just after 8 30 last night, an explosion rocked new york city as chelsea neighborhood, sending people running in panic. Lets go get off the streets be honest. You felt it in your heart. I heard a massive explosion then fire trucks and police cars. A massive response. Very unnerving. Reporter social media lit up and crowds grew as First Responders raced to the scene. A mangled dumpster was one of the first imaging to emerge, leading many to wonder, what caused the explosion . Theres no evidence at this point of a terror connection, but wnt indication is this was an intentional act. Reporter according to Law Enforcement sources, police have video of showing a man placing some sort of object into the dumpster. Multiple people were injured by the explosion and treated at local hospitals. Thankfully none of these are lifethreatening injuries. Reporter as polices work to clear the area, another device, a Pressure Cooker, was found a continue to investigate. Willie, this is a very popular area, with people going out at night, a lot of bars, a lot of restaurants. Where this explosion took place specifically, according to witnesses, was near a church which wouldnt have been very crowded at 8 30 at night. Also a school and Rehabilitation Center for the blind, but a couple apartment buildings, but a very crowded area with people going out and walking in the streets. None of those injuries were lifethreatening. As i mentioned at the top, you live in the area. You heard it, you felt it. Reporter i live overseas, but i keep an apartment very close to here, just down the block. I wasnt sure if it was an explosion. I heard a loud rumbling, but then just moments later, there was a very quick response, helicopters in the air, fire trucks, Police Moving to the area. This whole neighborhood last lights. Very impressive, very overwhelming response that seemed to start just machining after i heard that blast. Your was some of the first reporting from the scene. Thanks, richard. Richard engel in new york city. Another explosion it before at the jersey shore. Morgan, what can you tell us about this . Willie, good morning. Were standing where here in ceaseside heights, new jersey. Can you still see the rim of the trash can behind me. This happened 30 minutes into a race designed to support military veterans, but thankfully that race was already delayed, which means no one was here yet and no one was hurt, but the question was what was designed to have happened . That device was attached to other devices set to go off, but didnt. The race was immediately canceled. Their homes until 6 00 p. M. In the evening. This is being if investigated as an active terrorist, harkening back to the boston mar athan where three people were killed and up to 260 people were injured. The fbi is on the ground investigating. They still do not have a motive, do not have a suspect. People here in ceaseside heights are wondering who did this and why. Willie . Again incredibly fortunate morgan, thank you. A man with a knife attacked at least eight people with a mall in minnesota last night. Witnesses say he made references to allah. Good morning, gadi. Reporter this entire mall is a massive crime scene. We understand that seven of the eight victims have been released from the hospital, all of the victims here are expected to make a full recovery. About the knifewielding suspect. We are told he came to this mall wearing what was possibly a private security shirt, and may have asked people if muslim before attacking strangers at random. He was eventually confronted by an offduty police officers, he was shot. He was killed. The police chief responding to specific request questions about whether this was terrorism. The police chief saying theyre trying to do their due dili the fbi, but they are still interviewing witnesses, victims, and that could take some time, because that was a saturday night at the mall. A lot of people were here shopping. That offduty officer acting very quickly, perhaps saving some live. Gadi shall wards in minnesota, thank you. Peter, what are investigators telling you about the scene in new york city last night . On the explosions there is some amount of luck, first the jersey. The second the fact theres quite a bit of physical evidence, because one of the devices in new york didnt go off. The second improvised bomb in new york was intact when the investigators got to it. So analysts are looking for common features all the way down to how the wires were joined together. There are broadly speaking some features in common with what was planted in new jersey. Both the devices were set to go off with electronic timers. When the one in new jersey exploded, nobody was around because of the a delay in so that further suggests that bomb was not set to go off by somebody who was watching with a remote control. Officials say the new jersey device was composed the three bombs made from value gannized steel pipe like this bundled together. It did not explode complete lid. Only one of the pipe bombs went off and it may not have exploded entirely itself. Because of theres so much of that device left behind, investigators have a good idea how it was made even though it been assembled using instructions widely available on the internet. A similar guide was nope published by a al qaedainspired publication inspire. This morning federal Officials Say they have not concluded, willie, whether its all the work of the same person or the same group. Or if there is a link yesterday to terrorism, as mayor de blasio said. S former top fbi official, now the president of crowd strike services. Shawn, good morning. We have a dedicated device in the chelsea neighborhood, an undetonated Pressure Cooker in that same neighborhood, a separate device from earlier in the day from Seaside Heights he new jersey. What are they looking at . You have multiwall incidents, lots of physical evidence. Shrapnel and other forensic evidence that well see at the scene, where these two explosions occurred both in seaside and in chelsea. The investigators will be looking at these two things in new jersey and new york, separate types of investigations, but absolutely there will be coordination very close. While theres no direct evidence linking you this to terrorism, the joint Terrorism Task force working with defaulting to that. When i say that, youve got to look at what happened and how it happened. Weve seen these types of devices used oftentimes in terrorist incidents. Theyll default to that, because they have a very strong mechanism, a vehicle in terms of the jttf, a lot of expertise in going through physical evidence, evaluating it, and theyve got access to an awful lot of intelligence. Initial to the physical evidence, theyll be out talking somebody knows what happens, either coconspirators, neighbors, family member, coworkers who may have seen something. There will be a lot of investigation. Were only 12 hours into this, willie, so well expect lots of information to come out and the investigation will change as this in information is developed. Shawn, mayor de blasio made on point of saying theres no link to terrorism. Thats a murky word. You can be directed from overse inspired by a group overseas. At what point does Law Enforcement make that connection. It always comes down to who did it and why . The motivation. For some its ideological purposes, social or political means, somebody looking to influence or create chaos for their for that type of an agenda. Theyll look at that and too i it to terrorism. The jttf looks at this as a terrorist event if thats in fact the case. Thats a major concern where youve got individuals here who might not be operating at the direction of an organized group, but picking up information through social media. Theyre learning about how to create improvised explosive devices, still causing and creating the type of chaos that supports that at this point theres not that indication, but Law Enforcement is absolutely looking at that as one of the possible motivation, willie. Shawn henry, always appreciate your point of view and perspective on morning likes this. Meanwhile, president ial nominees Hillary Clinton and donald trump weigh weighing in Hallie Jackson is in miami. Good morning. Hi there, willie. Good morning. Both candidates responding in different ways. Just minutes after reports began surfacing. Hillary clinton talked about it later on that night on her press plane with reporters. I must tell you that just before i got off the plane, a bomb went off in new york, and nobody knows exactly whats going on, but boy, we are living in a time always wiser to wait until you have making conclusions. Reporter an aide tells nbc news clinton was informed of the explosion in chelsea just after her remarks at the Congressional Black Caucus dinner in washington, d. C. Thats where she delivered a blistering critique of trump without mentioning the name, and she went after his birther comments as well as president in fact born in the u. S. , obama saying last night, in other breaking news, the world is round, not flat. As always, politics swirling around the news. Hallie jackson, thanks so much. Lets get a check of the weather from dylan dreyer. Good morning, willie. We have some rain especially back towards oklahoma, where we have some heavy this morning moving through eastern oklahoma, but also attached we need rain in the northeast, but i dont think today is the day well get a lot of it.

As it moves into tomorrow morning thats where well see the best chance of heavy rain stretching down into the midatlantic, and then by the time in the afternoon well see the heaviest of the rain moves out. Elsewhere across the country, the midwest, temperatures in the 80s and a bit more wet weather in the pacific northwest. Now heres a peek out your window. And thats your latest forecast.

Of a group of kids like they were her own when a bus burst into flames. She was driving a load of Elementary School students in college park, maryland, when she saw flames around the bus. She stopped and sprung into action. As the fire spread, she went through the bus, ushering every last student to safety before the thing went up complete le. She then went back on the bus to make sure no child was left behind. She said she had only a small healthy act. And i really enjoy doing it. A lot of times these rooms are very hot, like saunas. And i guess thats a form of exercise. Now, gesturing may not be exercise in the classic get your heart rate up sense, but some experts did point out trump is on to something. Small movements like fidgeting can result in large calorie deficits by the end of the day. It works. Im very handsy when i talk. I dont know if its a weather thing or what, but who knew i was burning calories. Theyre working 23 hours a day. They dont have time to get to the gym. Our next high goes to a kid who some day may be playing on giants to draft him. My man is 9 years old and hes a beast. The Australian Youth rugby game here. Youre watching a man among boys. Oh, that poor little guy at the end. The poor kids trying to bring him down. Getting stiff armed, plowed over. Left littered over the field like dirty laundry. He drew comparisons to marshawn lynch, who earned the nickname beast mode for the way he ran over defenders. This kid, full and by the way, i want to point one thing out. Thats beast mode right there, but the break away speed, too. He can get away from everybody. Thats the secret. You need to run over people and have speed. Then its perfect combination. 9 years old. Hes ineligible for the draft. Our next low is the giant globe rolling through the streets of china. A site of u. N. Of the many midautumn celebration. Through from its base and began terrorizing citizens, deflating as it went, somehow, nobody was injured in this. The first image, though, that popped into many of our heads was this, yeah. Harrison ford, raising the bolder in raiders of the lost ark. Amazing nobody got mowed over in that thing. I wonder if it would hurt if you did. Its still a balloon. Hurt. Our next high is one of the greatest moments in broadcasting history. The 49ers played the rams. A fan ran onto the field. While tv cameras turned away, harlen provided the gripping play by play for his radio audience, all the way to when he was tackled by security. San francisco in the secondary. Somebody has run on the field. The 50, the 30, bar chested and banging his chest. He runs the opposite way. He runs to the 50, to the 40. The guy is drunk, but there he goes. The 20. Theyre chasing him. Theyre not going to get him. Raising his arms. Bare chested. Somebody stop that man. Here comes the blue coat. They got him. Coming from the left, oh, and they tackle him at the 40 yard line. He was really the best and now hes the best. People to get their own call. The final low goes to the level of art theyre throwing in new yorks guggenheim museum. The world renowned collection includes picasso, monet, and now this. An 18karat gold tollt. The museum says its a wink to the excesses of modern art. The good news is the can is full y functional and visitors can use it. Each use by precious metal experts. Its estimated the toilet is worth more than 1 million. So many puns there. So much to say. I mean, were flushing money down the toilet. Very nice. I like the idea of a guy with white gloves and precious metal cleaner coming in after every use. Thats what they have in the bathrooms here. Well see you in a minute. Still ahead today, the primetime emmy awards are party pool and show how this show is tackling diversity. And later, harry smit with the remarkable story of the im lucky to get through a shift without a disaster. My bargain detergent couldnt keep up. So, i switched to tide pods. Theyre super concentrated, so i get a better clean. Tide. Number one rated. Its got to be tide my dad gave me those shares, you know. He ran that company. I get it. Gotta manage your risk. An honest opinion is how edward jones makes sense of investing. Oh, here comes nancy. Shes not splashing. You can wear anything and pour bleach. And her whiter whites, just dazzling. Clorox splashless bleach. Also try crystals and packs. We got married in june. On tunaday. Theres a subway . 3. 50 sub of the day every day a different sixinch sub for just 3. 50 at subway . Every day of the week. Her name is teri. She was born on can i mess your hair up . Yes jimmy fallon going where few men have gone before, all you have in Donald Trumps show. Technology is changing our lives so quickly, you forget it was only a few years ago the idea of touching a button on your phone and having a car magically appear to take you home seemed like something from the space age. Now Services Like uber and lyft with the famous pink moustaches are part of daily life, but the ambition for its founder john zimmer goes far beyond just sharing rides. Look at this traffic. Yeah. Like most of us, john zimmer hates traffic. While most of us just curse and pound the steering wheel, zimmer is doing something to fix the problem. The is 2yearold president and cofounder of Ridesharing Company lyft got hooked on cars as a kid, but not just because they looked cool and went fast. He loved what they exploration. I remember being on the ground playing with cars getting over any obstacle. Is there a direct line . I think that freedom wasnt really there, and that the cars become more like a 9,000 ball and chain with all the maintenance, the parking. So i wanted to go to that original idea that made me so excited, but actually deliver the real freedom. John first noticed the number of empty seats during his drives ten of us would be driving back with just one or two vehicles. I learned that 96 of the time the car is parked. In 2008, zimmer left his job at lehman brothers, just before the company crashed, to pursue his vision of ride sharing with partner logan green. Four years
