good evening. and we're just back from manchester, england, tonight. where there is breaking news on several fronts. the raids under way after the terror attack at a concert. tonight the bomber, what we learned and was his brother about to bomb again? heavily armed police teams raiding several sites around manchester tonight. tonight, we have new images of pieces of the bomb itself and what they reveal. we begin with abc's chief foreign correspondent terry moran in manchester. >> reporter: in the terrible moment the bomb went off -- >> oh, my god! >> reporter: -- it left behind, amid the carnage and fear, clues to how it was made, and by whom. tonight, those crime scene photos obtained by "the new york times" and posted on their website reveal the bomb's sophisticated design -- the possible detonator, bloodied, carried in the suspect's left hand, investigators believe, with a small circuit board soldered inside and a protruding red wire.

a mangled 12-volt battery, more powerful than those seen in most suicide bombs. nuts and screws used as deadly shrapnel. and part of the blue karrimor backpack the bomb was carried in. investigators now concluding that this bomber was no lone wolf. >> i think it's very clear that this is a network that we are investigating. >> reporter: this morning, police stormed a building in central manchester, targeting a third floor apartment. neighbors told us they thought it was being rented as an airbnb unit. >> and you can't know who everybody is. >> reporter: while we were there -- police have been at this location for about three hours. and all of a sudden they have tackled this man here. they're making some kind of arrest. we don't know if it's related to the attack or not, but things happened very fast here. it turned out, a police officer had simply been trying to break

up a fight, and tonight, police say all the victims have now been identified. stilling the faint, last hopes of so many. like charlotte campbell, who desperately sought her 15-year-old girl, olivia. >> olivai, mummy loves you. please just phone me and come home please. >> reporter: tonight, olivia, too, among the dead. >> just heartbreaking for charlotte, who the world watched in that tearful plea. terry moran for us tonight from manchester, police in that city now searching for any possible accomplices and they're preparing for a huge public event this weekend? >> they are, david. even as the memorial here goes, the great manchester run and city games, the largest 10k run, 35,000 runners last year, will go forward this weekend, authorities say, safely. david. >> terry, our thanks to you. and the bomber himself this evening, just 22 years old. he had just returned to england five days before the attack. so, where was he right before

and was his brother about to unleash another bomb? and tonight, what they have just discovered in the suspect's home. here's abc's chief investigative correspondent brian ross. >> reporter: tonight, these pictures on the front page of the british tabloids. salman abedi, as a british schoolboy, and a goofy-looking teenager at the beach. no indication of his rapid road to jihad. but tonight, we are learning abedi had been recruited by isis, and that five weeks before the attack he traveled to libya, an isis stronghold and his family's ancestral home, returning to manchester may 17th -- just five days before he set off his bomb. officials in libya today say they have arrested the bomber's father, who in this interview just before the arrest denied his son was a terrorist. authorities also arrested the bomber's younger brother hashim, who they say confessed he was in the process of carrying out what they called his own act of

terrorism and knew exactly how his brother's bomb was made. isis has posted videos online showing how to build a variety of suicide bombs. but experts say the details in the manchester bomb show greater sophistication, including a design like the one used by isis for bombs in paris and brussels, and more than one detonator. >> really suggesting that he probably did not act alone, that he probably had some help, that he certainly had some advice on how to create the bomb. >> and of course, that was the concern all along. brian ross with us. brian is just getting information in about what investigators have now found in the suspect's home. >> that's right, david. it was described to me as kind of a bomb workshop. a large quantities of unused chemicals more than enough for several more bombs. >> and concern for what his brother might have been planning. brian ross and your team. thanks to you. we do have a breaking headline here at home now, several reports of tornadoes coming in already, watches in several states at this hour.

this twister touching down near the coast of georgia over the last 24 hours. powerful straight-line winds flipping over this tractor-trailer on i-10, west of houston. tonight, those storms now tracking north. millions in the path as it moves up the east coast. abc's steve osunsami is in atlanta. >> that looks to me like a tornado. >> reporter: right before dinner tonight, tornadoes were touching down north and east of charlotte, hitting homes and at least one elementary school that fortunately was empty. the evening ride home turned into a mess. >> the tree is now down across i-77 southbound. >> reporter: this same storm system sent families running to their basements in north carolina tuesday evening. >> get in the middle hallway right now. >> reporter: an ef-1 tornado ripped the roof off their fire station and destroyed all but one of their engines. the volunteer firefighters made it out alive after they took cover underneath their trucks. north of atlanta, where the soils are saturated. high winds knocked over this large tree on top of this home where someone was asleep in the bedroom upstairs.

luckily, everyone is okay here tonight, david. >> steve, our thanks to you. let's bring in rob marciano. tracking to all for us tonight. hey, rob. >> reporter: hi, david. we have tornado watches and warnings ongoing. let's get right to the radar. florida actually finally getting some much-needed rain. but these line of storms have really been doing some damage. moving towards west palm and del ray. tornado watches encompass much of the southeast. georgia, carolinas. severe threat by 7:00 a.m. should be over. philly, pittsburgh, back to detroit, rain. wet for much of the day. from new york to boston, right on through friday. this is a large, stacked system. with the northeast for at least a couple of days. >> all right, rob marciano tracking this into the night for us. rob, thank you. we turn next here to a major headline involving president trump and the russia, "the new york times" just now reporting that american spies learned last summer the russian officials were discussing how to influence president trump through his advisers. abc's pierre thomas.

>> reporter: "the new york times" is reporting that u.s. intelligence officials allegedly obtained evidence russians bragging about the fact they could use his advisers as a way to influence donald trump's views on russia. according to the times that intelligence apparently played a role in the decision to launch an fbi investigation into whether there was collusion between trump campaign officials and the russians. former cia director john brennan testified that he asked for an fbi investigation after he claimd intelligence showed communicationd between trump associates and russian officials. abc news has not independently confirmed "the new york times" report. it's unclear if it's true. a serious investigation is now under way, headed by former fbi director bob mueller. >> pierre live with us, we're learning more about how the intelligence community has been spying on russian officials for months. what's the primary concern about what they found? >> david, the intelligence

community is saying they have evidence that trump associates with talking to top russian officials. and they're demanding that the fbi get to the bottom of it. >> pierre thomas on the story next to another developing headline involving millions of americans who could lose their health insurance. at town halls across the country, we have reported on americans angry and concerned, asking questions about what will happen to their insurance. tonight, the new independent report just out. looking at the new plan that just passed the house to repeal and replace obamacare. how many fewer americans will be insured over the next decade? abc's mary bruce on the hill tonight. >> reporter: for months, americans have crowded town halls, voicing fear and frustration. president trump and republicans have already declared victory. >> this is a repeal and replace of obamacare, make no mistake about it. >> reporter: and tonight, we finally know what the house healthcare bill could mean for you.

the congressional budget office releasing their report card, finding the bill could leave 23 million more americans uninsured, and reduce the deficit by $119 billion over the next decade. for some, their premiums could skyrocket. a 64-year-old making roughly $26,500 in some states could see their premiums climb nearly $12,000 or more. those concerns around the country, fueled by last-minute changes to the bill that would allow states to opt out of guaranteeing coverage for basic health services, like maternity care and even ambulances. and states could waive the requirement that insurers don't discriminate based on pre-existing conditions. even republicans admit that has to change. >> we've got to deal with pre-existing conditions in a way that we know will actually work for people. >> reporter: the report warning that over time, it would "become more difficult" for people with those conditions to purchase insurance because their premiums would "continue to increase

rapidly." it's far from a done deal. the senate is now starting from scratch and some republicans are skeptical they'll ultimately get this done. are you confident that this is still going to get done? >> no. i'm not confident. i think it's -- i think it's -- i don't know what the odds are. it's going to be a tough call. >> and mary bruce live with us tonight from capitol hill. mary, now that these new numbers are out, the senate can finally get to work but the path forward you were telling us earlier is not very clear. >> reporter: david, here in the senate there are serious concerns about this bill, even from republicans, majority leader mitch mcconnell today admitting at the moment he doesn't know how he's going to get those 50 votes he needs to get this done. david. >> mary bruce, thanks, mary. president trump and the pope today, they're meeting at the vatican. although they have had very public differences over the past year. as the president was leaving, he was heard telling the pope, i

won't forget what you said. abc's chief white house jonathan karl on the gift from the pope that sent a signal. >> reporter: the pope and the president -- the ultimate odd couple. >> welcome. >> thank you very much. this is such a great honor. >> reporter: their meeting may have seemed a little awkward at first -- a beaming president standing next to a stoic pope francis. after it was over, though, the president called the meeting an honor. >> he is something -- he is really great. we had a fantastic meeting. >> reporter: it wasn't long ago that these two men had a very public feud, the pope last year saying then-candidate donald trump's call to build a wall was "not christian." candidate trump reacted angrily. >> for a religious leader to question a person's faith is disgraceful. >> reporter: but today, here at the vatican, the two beginning with a friendly handshake. the pope gave the president a copy of his encyclical, where he makes a passionate case to

fight climate change. at a meeting today, the vatican urged the president not to drop out of the paris accord on climate change. the president promised to consider the pope's request. and right before he left the vatican -- >> i won't forget what you said. >> reporter: a sign the president may have been moved by what he heard. >> the president there saying to the pope, i won't forget what you said. let's get to jon karl. he's in brussels tonight on the eve of the nato summit. jon, you covered then-candidate donald trump who said famously, he thought nato was obsolete. now he meets with some of those very leaders. he's not expected to back down on what some of he said, either. >> the united states pays the overwhelming cost of nato's defense. he said as a candidate, our nato allies need to pay more and he's saying that as president. but, david, he's definitely no longer saying that nato's obsolete. he'll say tomorrow that nato is essential. >> you'll be right there, jon. jon karl reporting tonight.

jon, thank you. next tonight, as we report on the terror overseas and concerns about what could be brought on the planes, we're learning tonight that the tsa is now testing new screening procedures. those changes include -- requiring passengers at some airports to remove electronics from their bags. anything bigger than a cell phone. let's get to david kerley live at reagan national. hey, david. >> reporter: good evening, david. the concern here is that everyday items like electronics that can look like explosives in x-ray machines and this comes as the tsa is considering expanding and extending that laptop ban. now, the current screening machines now give out one-dimensional picture. sometimes that's difficult for screeners to get a clear picture. they're testing at 10 airports now, new procedures that require passengers to put any electronic device larger than a cell phone in a bin. tsa has been testing this for a year already, no word on whether or if they'll implement this
