[ gunshots ] police shouting at pedestrians to run. >> go! go! >> reporter: authorities quickly arrived at the scene, locking down parliament. >> this house is now suspended but please wait here. >> reporter: the attack unfolding just before 3:00 p.m. on the busy westminster bridge, just before rush hour. the suspect's car careening onto a sidewalk. plowing through pedestrians, killing at least two and injuring around 20 others.

>> there was bodies literally -- >> there must have been, like, ten bodies. >> 10, 12 bodies. >> in different places along the bridge. >> reporter: moments later, that car crashing into this gate outside parliament, just below big ben. the car smoking, its hood smashed, the driver's side door open as crowds begin to form. >> i see that one car smashed in the wall and just people started running all over. >> reporter: from above on the famous london eye, these tourists watching the carnage below. >> we were in the eye. we saw different groups of wounded people on the bridge. one of the things that struck us was how long medics were spending with the victims on the ground. >> reporter: authorities say the suspect then exits the car to continue the deadly rampage. inside parliament's grounds, stabbing and killing a police officer who was standing guard. one witness watching from a window. >> we saw a thick-set man in

black clothes. had something in his hand, it looked like a stick and we could see the man moving his arm in a way that suggested he was either stabbing or striking the policemen. >> reporter: police fire, taking the suspect down. these images and immediate aftermath show one officer seeming to point his gun at the alleged suspect. what appears to be a knife under the officer's right foot. police load the alleged suspect onto a stretcher and into an ambulance. the suspect later dying. parliamentarians on armed guard. theresa may rushed to safety. outside, that bridge brought to a standstill. bystanders rushing to a victim's aid. first responders performing triage as helicopters were dispatched to rescue the wounded. tonight, a search is under way to make sure there were no other attackers as stories of heroism begin to eearnimerge. to bias ellwood with his face

bloodied, performing mouth to mouth on the officer that later died. >> such a grizzly scene. alex is joining us outside of london now, and theresa may as addressed her nation saying they believe the suspect acted alone? >> reporter: they believe this attacker acted alone, and they have not identified the suspect and there has been no claim of responsibility. prime minister may called this a sick and depraved terrorist attack, adding that londoners will never give into terror, and parliament will be back in session here tomorrow. tom? >> it will be a long night for you, thanks so much. stay safe. authorities have launched a full terror investigation especially because the attacker used a vehicle to kill. a terror method we have seen before, and heightened security in the united states as well. heavily armed police standing outside the british kons late in new york, but they have

collected key information. abc's senior justice correspondent, pierre thomas, on the story. >> reporter: tonight british authorities are close to identifying this man, suspected of the deadly attack in london seen here, just after the fatal takedown. sources say they have a name but they are still working to confirm the identity. >> we currently believe there was only one attacker. >> reporter: investigators are now urgently scouring the car he used in the attack and are searching for the suspect's smartphones and computers. in recent weeks, british counter intelligence officials have publicly warned about a possible attack using a car and a knife. precise the crude type of attack isis has been calling on followers worldwide to carry out using any means necessary. >> this type of attack does not require anybody to go to any training. all you have to do is drive a vehicle and be able to hold a knife. >> reporter: last summer in nice, france, a huge truck plowed through a crowd. killing 86 people. during christmas season in berlin, 12 dead and nearly 50 injured killed in another truck attack. that tactic used in the u.s. too at ohio state university when a student rammed into a crowd with

his car then stabbed multiple people. >> and pierre joins us live now outside of fbi headquarters. pierre, we now know here in the u.s., some airports vigilance. >> reporter: they are stepping up at landmarks, but they have no intelligence pointing to a plot at home, but they are worry about copycats and they are urging vigilance. >> pierre, thank you. at the same time, that london attack was playing out, a major conference on fighting isis was taking place in washington. 68 countries represented. abc's chief global affairs correspondent, martha raddatz, on the fight overseas and here at home. >> reporter: today, just 30 minutes before the deadly attacks in london, secretary of state rex tillerson was praising the progress made against isis. >> hard-fought victories in iraq and syria have swung the momentum in our coalition's favor.

>> reporter: the state department saying 62% of the terrain isis once controlled in iraq than liberated, 30% in syria. more than 19,000 targeted strikes have removed tens of thousands of isis fighters from the battlefields. but the greater the success on the battlefield it seems, the more desperate isis becomes, urging followers to slaughter westerners with "a knife, or run over him with your car." in britain alone, some 850 people have traveled to syria and iraq to support isis. about half of those have now returned to the united kingdom. >> and martha joins us live now. martha, you mentioned that terror summit, and secretary of state tillerson talked about the strategy curving isis' online influence? >> reporter: he said the internet is the best weapon isis has for radicalizing, and he said the u.s. and its allies must break the ability of isis

to spread its message, but that's a tough goal to reach. >> thanks so much. next to that other major development tonight involving president trump's former campaign chairman and his ties to russia. paul manafort led the president's campaign during a critical time. you see him here with candidate trump at the republican national convention. tonight, a new report that he was paid millions of dollars to promote the russian interest of strongman, vladimir putin, and coming forward with new information about the intelligence community, monitoring communications of trump team. here's abc's white house correspondent, jonathan karl. >> reporter: operation pushback. the republican chairman of the house intelligence committee came out today to say the communications of some trump associates and possibly trump himself were picked up by u.s. intelligence after the election. >> i recently confirmed that on numerous occasions the intelligence community incidentally collected information about u.s. citizens involved in the trump transition. >> reporter: "incidentally collected," in other words,

the trump associates were not the primary subject of surveillance. for example, if u.s. intelligence was monitoring the communications of a foreign national say, the russian ambassador, they could have picked up his conversations with members of the trump team. that's a far cry from the president's accusation that his pr predecessor had trump tower wiretapped. >> do you feelel vindicated by chairman nunes? >> i somewhat do. i must tell you, i somewhat do. >> reporter: but remember president trump's allegation "how low has president obama gone to ta. p my phones during the very sacred election process. this is nixon/watergate. bad guy." the president said that president obama tapped his phones. have you seen -- >> no, no, no. that did not happen. >> reporter: fbi director james comey told congress point blank: there is no evidence to prove the president's allegations of wiretapping. and he also announced the fbi is investigating whether the trump

campaign colluded with russians. today a new revelation about a tomorrow top trump associate in russia. the ap obtained documents showing that from 2006 to 2009, former trump campaign chairman paul manafort was paid $10 million for work for a russian billionaire close to putin. in memo to his client, manafort described how he could help the russian president. we are now of the belief that this model can greatly benefit the putin government. we will be offering a great service that can re-focus, both internally and externally, the policies of the putin government. so would trump have hired manafort if he knew about this. >> i don't know. to look back, and to say, if we know now what we knew then, that's a question we would have to weigh at the time. >> he didn't know in. >> of course, not. >> he would want to know, wouldn't he? >> maybe. maybe. maybe not.

>> reporter: from paul man no fort tonight, once again, smear and innuendo are being used to paint a false picture. >> yet again another denial from manafort, and jon joins us. let's go back to the comments of congressman nunes claiming that they picked up communications from trump associates and a lot of democrats are outraged with that statement. >> reporter: they are, and the top democrat on the intelligence committee, adam schiff, said that nunes is more concerned with defending trump than leading the committee's investigation into russian interference. he said today, nunes needs to decide whether he is the chairman of an independent investigation or a surrogate of the white house. he cannot do both, and as you remember, nunes was a key player on the trump transition, tom? >> a battle within that intelligence committee. jon, thanks so much. in the meantime, the republicans are facing a health care plan that is now on life support. the house is set to vote tomorrow, and they don't yet

have the votes. here's the math. there are 430 current members of the house of representatives. they need 216 votes to pass, and by our count, they are seven votes short. they are trying to convince lawmakers to get on board. abc's mary bruce on capitol hill tonight. >> reporter: on capitol hill, a frantic day of closed-door negotiations. and tonight, with just hours until that crucial health care vote, some republicans are slamming the brakes. >> it's not going to pass as it stands right now unless they make major changes to it. >> reporter: today the president and vice president both met with holdout,s, but their personal pitches are falling on deaf ears. >> nothing. nothing has changed. >> reporter: emerging from a last minute meeting, the head of the conservative freedom caucus says they are standing firm. >> the opposition is still strong. they don't have the votes to do this tomorrow. we believe that they need to start over and do a bill that actually reduces premiums. >> reporter: by our count at least 28 republicans are still a no.

more than enough votes to kill the bill in the house. should the house delay the vote? >> they're going to have to. they don't have the votes. >> reporter: opponents are demanding further changes. the original version of the bill would leave 24 million fewer americans insured over the next decade. and some older americans could find themselves spending thousands of dollars more a year in premiums. the white house is negotiating but insists this is their best shot to overhaul obamacare. >> there is plan "a," and plan "a." we're if i can get this done. >> reporter: but the white house is well aware the resistance may be too much. >> mr. president, if the house repeal bill fails, will you keep trying? >> we'll see what happens. >> reporter: tonight, some republicans are coming around. congressman lou barletta is now a "yes" after negotiating a swap the president promising to support one of the congressman's legislative priorities in exchange for a vote on health care. >> i knew if i held out long

enough, you know, eventually -- >> reporter: you would get what you want. >> they'd send in the big guy to close the deal. >> mary bruce joins us live from capitol hill. we heard shawn spicer say there is only plan "a." republican leaders say they will go i a head with this vote tomorrow, but tonight, there is a real fear about whether they have enough votes. >> reporter: tom, the white house and republicans tonight are scrambling to negotiate, hoping to push this across the finish line, and despite the impacts, i'm told tomorrow's vote is still a go. >> mary bruce, thanks so much. there is much more ahead on "world news tonight" this wednesday. the possible hate crime, the alleged attacker caught on camera. the well-dressed murder suspect running down the streets of new york. his disturbing motive revealed. and the desperate search under way at this hour. the cruise ship passenger lost at sea. and celebrating the self-proclaimed king of daytime television, the game show
