>> announcer: from abc news, this is "world news now." >> good morning to you all. we begin with the deadly terror attack in the heart of london. >> okay. here is the situation. parliament is expected to reopen today in london, but the surrounding area this morning remains a crime scene. this after that knife-wielding terrorist went on a rampage. live pictures that we're seeing right now from london at this early morning stage. that terrorist used his car to mow down dozens of pedestrians on the westminster bridge. >> the attacker then crashed his car and fatally stabbed a police officer inside the gates of parliament before police ended that ramp and with a bullet. just yards away from the entrance in the shadow of big ben. >> and now hundreds of law enforcement officers are scrambling to pindown the attacker's identity and his possible motive. abc's al mex marquardt is in london this morning and starts off our coverage.

>> reporter: police say around 40 people were wounded in the afternoon's attack and five were killed including a police officer and three civilians. the attack started at 2:40 p.m. as a car drove across westminster bridge, then swerved suddenly, karining into a crowd of pedestrians. at least one person falling into the thames below. the attacker then continued in the car plowing into the entrance to parliament, getting out with a knife and at that point fatally stabbing the police officer. other police officers responding, shooting and killing the attacker. police say they believe they know the identity of the attacker. they say that he acted alone. he was likely inspired by islamic extremist terrorism and a short time ago, british prime minister theresa may called this a sick and depraved terrorist attack adding that londoners were never give into terror and that parliament will be backup in session right here again. >> and alex tells us that london has the largest closed circuit tv network i

so several cameras captured the terrifying scene. >> here's some surveillance video of the moment of that attack. you can see where the car is driving across the bridge. we're also hearing some chilling accounts from witnesses who were on the bridge when it happened. >> once i got off my bus, i heard one guy come running to the police officer that was next to me. that he needs help, that his wife had jumped into the river to avoid getting knocked over. i could see people looking over into the river to see. i don't know what they were looking at in the beginning and then after i heard that his wife had jumped in, it looked terrible. >> now, that woman who did jump into the river she was recovered from that river and she's in the hospital this morning in serious condition. and among those who were killed were three peds who were mowed down on that bridge. >> a doctor who treated the wounded from the bridge also

called catastrophic injuries. >> britain's most senior counter-terrorism officer is calling this attack a case of islamic related terrorism. >> stepped up security efforts are under way here at home, as well. let's turn now to abc news contributor and former fbi counter terrorism specialist steve gomez from our los angeles bureau. steve, we appreciate you coming on. what do you make of this? >> well, it's another classic isis-related type of attack. isis inspired where you have a lone wolf that is probably looking at propaganda, messaging that's on the internet and decides to go out and commit an attack and this method that he used is one that isis has said to their followers to go out, get a car, get a knife, get a rock, throw people off from a tall building. and go out and kill people where you are. don't travel. just do it where you live. and kill people. and what we see here is a clack

instructions were and him carrying those instructions out. >> and steve, as we take a look, we saw that video of the vehicle mowing down those people there on westminster bridge, diane, myself, i'm sure you're all familiar with this particular area of london. it's a fairly secure area. you see this car going down westminster bridge but still he's able to penetrate the perimeter. does it seem as if there was a lack of security there? >> the bridge is a well-known bridge. a good friend of mine told me every time they go to london, they always go to that bridge and take pictures with the family. that's a place where people go. it's very well-known but it's fairly vulnerable. >> but then the car crashes into parliament and he's able to run in and still able to stab a police officer. >> exactly. i think part of the idea about maybe going after the people opt bridge is one, it's vulnerable. and two, that creates chaos. so the objective of hitting people and kill people is being

creating chaos so the officers will be deploying over to the bridge and then he crashes into the gate and now they have to deal with that person there, you know, with a hash yet or a knife and now you've got all kinds of problems going on. that's probably part of the game plan. we'll have to see as the investigation continues. >> steve, i wonder. you're talking about an area just outside of parliament, in this case even through the gates of parliament. the prime minister was just a few more yards away. if you can't defend against something like this there, where can you? >> exactly. i mean, the use of a vehicle, it's an incredibly difficult situation to try to guard against because it's very unpredictable. anybody can get into a vehicle, anybody can get a knife. formula one of that is registered. you have to know how to drive a car. when have you something like this you have no idea when this is going to hit you at any moment, it could happen. that's what we see here. almost have to start looking at putting the barriers out a

expanding that layer of security outside of these targets. >> we've seen it happen in nice, in berlin, and now in london as well as in ohio state here it appears to be the new norm. sad new norm. >> absolutely. no, that's what this is all about now. isis put that information out there. and their followers are following it. that's unfortunate. now we've got to deal with it. >> abc news contributor steve gomez live for us from los angeles. thanks a lot. >> we'll continue to have coverage of the terror attack there in london throughout the morning as well as on "good morning america." we want to talk about the other big story taking place in this country. today marks seven years since the signing of the affordable care act, but also the day the house votes on the republican bill to eliminate what became obamacare. >> and an probable of that new bill, the american health care act, may go down to the wire. the conservative freedom caucus is the main obstacle at the moment.

essential benefits from the ahca such as maternity care. the chairman of the caucus is negotiating possible concessions with the white house. and house democrats are criticizings comments from intelligence committee chair devin nunes. he says then president-elect trump's communications were collected incidentally. then shared by u.s. intelligence. he also chamed they aren't released to the fbi's russia probe. the committee's ranking democrat add mam smif renewed the call for an independent investigation and said he's seen more than circumstantial evidence of trump associates working with russia. a police officer and three others are dead after a shooting spree in wisconsin. the shooting started as a domestic situation at a bank. police say a second shooting was at a law firm and the third at an apartment complex. that's where the officer was fatally wounded. the suspect ended up in a standoff with a s.w.a.t. team. witnesses say they heard dozens of gunshots and about 100 officers were on the

custody. a maryland man accused of fatally stabbing another man because of his race. police say james jackson randomly picked out timothy caughman, a black man as you can see checking bottles on the street in new york city. jackson was allegedly armed with a 26-inch sword. he was captured on video after the alleged attack. police say he wrote a manifesto about attacking black people. >> it's well over ten years he's been harboring feelings of hate towards male blacks. the reason he picked new york is because it's the media capital of the world and he wanted to make a statement. >> police say jackson may have been considering other attacks but a day after the stabbing he turned himself in to police saying he was the person they were looking for. newly released surveillance video shows a rescue of a man who apparently had a little too much on st. patrick's day. so if you look at the video, you can see he's having trouble walking a straight line.

tracks. >> oh, a group of tufts university students immediately jumped onto the tracks to lift him to safety. risking their own lives, mind you. a minute or two later, a train pulled in on the track where the man had been lying. >> yeah, so frequently in situations like that, people look at each other and expect someone else to do something and no one ends up doing anything. he's really lucky he was surrounded by people who didn't hesitate and jumped right in. >> they jumped in there. coming up, fighting isis. the new efforts under way right now to take backup the terror group strongholding in syria. >> and later wyclef jeans speaks about his experience with law enforcement and the lessons he wants everyone to learn from his experience. you're watching bnz.
