pressure cooker with exposed wires, recovered by police. who are investigating it tonight. there are more than 1,000 additional officers including the national guard patrolling the streets of new york right now. and fears that it may be connected to another blast earlier in the day in new jersey. we begin with linzie janis at the blast site. >> reporter: tonight, the massive manhunt for the person or people responsible. for this terrifying scene. >> we know there was a bombing. that much we do know. >> reporter: surveillance images captured the moment this pow herb -- powerful blast strikes. just past 8:30 p.m. >> a bomb just went off in new york. >> reporter: this man walked towards the scene in shock. debris, everywhere.

>> reporter: within moments law enforcement descending on 23rd street. >> ma'am, get off the street with your kids! >> there was an explosion from a garbage pail. have units stay off the block. >> reporter: the force of the explosion blowing out windows. >> we just ducked. >> reporter: shards of glass and shrapnel. flying like missiles. >> i thought in my mind, a building was collapsing. >> reporter: ramon lopez racing to help this woman, bloodied and dazed. >> come with me. come with me. come with me. i'm helping you. you're okay. nothing is going to happen to you. >> reporter: first responders leading the injured into ambulances. >> all of a sudden we hear, boom! it was loud, and shook the building. >> reporter: investigators begin sifting through the debris.

dumpster, now a heap of twisted metal. >> this was an intentional act. >> reporter: then, word that a second suspicious device had been found just four blocks north. we've just been moved out of this area, near 26th street. the police telling us this is a hot zone, and they're looking at another device. two former new york state troopers finding this pressure cooker. residents told to stay away from windows. the neighborhood, still an active crime scene. found a link to international terrorism. >> what was the motivation? we do not know it yet. >> linzie, what are we learning about the more than two dozen injured? >> reporter: tom, i spoke with the fire commissioner earlier, he told me most of the injuries were shrapnel, glass, also people falling in the chaos. most of the 29 injured have been

all have now been released. >> linzie, thank you. while authorities are calling the blast intentional, investigators are pouring over evidence from the crime scene as the hunt for the bomber or bombers continues. brian ross with the manhunt tonight. >> reporter: as authorities tonight hunt for a bomber on the loose, the most important clue could be the device that did not explode, a pressure cooker connected to wires and a cell phone, found four blocks from the first blast site in a white plastic bag. apparently triggered in some manner by a cell phone. >> the word is both devices are pressure cookers, similar in construct. >> reporter: the new york police bomb squad used a robot to remove the device, and then sending it to a lab.

and registration on the cell phone. >> we want to do so intelligently, move forward, right now that is evidence that could be crucial to our case. >> reporter: investigators marking every tiny piece of debris on the street. they have determined the explosive was a commercially available substance called tannerite. police are also doing a slow motion analysis of the surveillance video of the scene to see if the bomber could be among the pedestrians before the blast. and afterwards, to see if the bomber use the chaos of the moment -- >> explosion from a garbage pail. >> reporter: to cloak his getaway. >> and brian ross joins us now. are there any suspects at this hour? >> at this point, no suspects are in custody at all. and there has been no claim of responsibility by a terror

but pressure cookers have been used by terrorists around the world. most recently, at the boston bombing three and a half years ago. and whoever was responsible, it certainly was terrifying and terrorizing to the citizens of new york. >> brian, thank you so much. and we're learning more about the pipe bomb earlier in the day that was detonated on the route of a charity race to raise money for marines. no one was injured, but as gio benitez reports, the blast could have been deadly. and authorities are not ruling out a connection to the new york bombing. >> i got some type of explosion inside of a garbage can. >> reporter: tonight, federal investigators looking into whether a pipe bomb that tore apart this trash can in new jersey is related to the bombings in new york city. >> shut down the run, get them out of the boardwalk. >> reporter: officials honing in on the cell phones used to

saying they appear to be similar types of phones. >> they are terrorism, though. there's no doubt about that. they are terrorism. >> reporter: the bomb was set to go off along the route of a charity race for the marine corps. >> it was a loud boom, like a bomb. the explosion was probably 20 feet high. >> reporter: luckily, the race had been delayed because of a large turnout. no one was in the area when the bomb exploded, and there were no injuries. >> if the ra started on time, we could have very well been dealing with an event with multiple casualties. >> reporter: the event is similar to the 2013 boston marathon bombings that killed three and injured hundreds of others, in what could be a copycat attack. and this is where that bomb went off. tonight, we know there were three components to the bomb, all wired together. but only one went off. tom, this could have been so much worse.

and meantime, the mall security in minnesota calling a stabbing -- shoppers running for cover after a man in a security guard uniform talking about allah chased people. eva pilgrim on what investigators are now learning. >> reporter: tonight, the fbi investigating about whether the man who went on a stabbing rampage had ties to terrorism. >> we are investigating this as a potential act of terrorism. >> reporter: today, isis calling the man a soldier of the islamic state. who acted in response to calls to target citizens. authorities say the attacker made references to allah during the five minutes of terror he brought to this mall. >> there was at least one victim who was asked if they were muslim. >> reporter: stabbing nine

the police now scouring mall security video. >> you saw him lunge at the police officer, and the officer then fired a few rounds. you see him fall, and you see him get back up. >> reporter: police say the attacker got up three times before the fatal shot. the officer, jason falconer, being called a hero. tonight, authorities are searching the attacker's home, trying to figure out what motivated him to walk into this mall and hurt nine people. tom? >> eva, thank you. and i want to bring in pierre thomas, three separate events. all have hallmarks of terror. as i watch our coverage, i'm amazed no victims were killed today. what are your sources saying about any possible links? >> they don't believe there are

but authorities are investigating whether the new york and new jersey bombings are linked. there's intense focus on cell phones apparently used in each attack. make no mistake, this is an extremely intense situation for law enforcement. these three cases are a reminder that the country remains in a high threat tempo environment. and with isis claiming credit for inspiring the minnesota stabbing, remember the fbi has identified roughly 800 isis sympathizers in the country. in the new york area, these incidents also have very bad timing. the united nations assembly is set to begin tomorrow in new york. so, what was already a security headache is now wrapped in an extra layer of concern. tom? >> pierre, thank you. and both presidential campaigns are responding to the attacks. donald trump saying we're going to end it. as hillary clinton released a

insult, an insult to my legacy, if this community lets down its guard. >> reporter: hoping to shore up support with minorities, trump is trying to put the birther movement he led behind him. >> president barack obama was born in the united states, period. >> reporter: obama mocking trump in his response. >> i am so relieved the whole birther thing is over. >> reporter: but as trump drops one false conspiracy theory, he's spreading another. >> hillary clinton and her campaign of 2008 started the birther controversy. >> reporter: that's not true, but today that didn't stop the trump campaign from repeating the claim. >> what is the proof? >> well, i just would refer you to news reports. >> reporter: clinton is not letting trump off the hook. >> we need ideas, not insults. >> reporter: but with his poll numbers surging, trump is unfazed. >> starting in 2017, anything we

achieved. >> reporter: and with the first debate eight days away, terrorism will likely play a bigger role. both candidates already prepping, sources say clinton has found a trump stand-in for rehearsals. tom? >> mary, thank you. next to florida, where a massive sinkhole has opened. despite what authorities are saying, as gloria riviera reports, residents are concerned. >> reporter: tonight, growing concern over this leak that's spewed toxic waste into a water supply source for millions of floridians. the leak, a problem for more than three weeks. an employee of the fertilizer company mosaic discovering this massive sinkhole, 45 feet wide in diameter. so far, 215 million gallons of what the company says is only slightly radioactive water has been released.

says, "we did not notify residents because there has been no offsite impact and no impact on residents." but not everyone is convinced. >> the first word that comes to your mind when you hear radioactive is cancer. >> reporter: mosaic says it immediately notified the epa and dep and began removing the tainted water, but the recovery process could take months. gloria riviera, abc news, washington. >> gloria, thank you. much more ahead on "world news tonight." after this man says his phone burned his leg. take a look at that. the lawsuit filed tonight. and a fire on a plane sends it crashing into a home. but get this. the passengers and pilot all survived. how they escaped, just in time. romantic moments can happen spontaneously,
