within a mile of each other. >> ladies and gentlemen, please reeve leave the area. >> i saw loads of people run away from the market. people lying on the ground. >> reporter: it started a little before 11:00 p.m. london time. witnesses saying multiple people hit when a van crossing the london bridge allegedly striking groups of people. the bbc reporting that at least one person is dead. >> i can't tell you anything at the moment. i need you to move towards safely. >> reporter: this person tweeting a photo of the immediate aftermath. people tending to the injured on the bridge. >> saw loads of police cars turning up and there was a period of quite intense gun fire. >> reporter: nearby, at this london restaurant in borough market, police yelling, "stay down." evacuating the restaurant as a precaution. this eyewitness describing the chaotic scene. >> two armed police

three shots. >> reporter: at this hour, metropolitan police tweeting, "the incidents at london bridge and borough market were declared as terrorist incidents." >> incredibly violent and dangerous scene in london tonight. jennifer eckelson joins us live now, and jennifer, there's still an active scene right now and radio stations have been given instructions from police? >> reporter: yes, tom. police asking those radio stations to broadcast to anyone at the scene that they must run, hide and tell. that is, if you see something unusual or out of place, say something. tom, an alarming request for a city once again under attack. >> some chilling instructions tonight. all right, jennifer, thank you. turning now to our producer near the london bridge, where the first attack occurred. what are eyewitnesses saying they saw and heard? >> reporter: well, eyewitnesses said they saw a van, a white van, careen down from the north side of the bridge to the south, zigzagging across, trying to

sort of run over as many people as possible. and basically they also saw that once they crashed that van, three men got out and they were apparently armed with long knives. now, other eyewitnesses also said that there were police not in uniform, but dressed all in black, and they were trying to tackle these men, but whether these men are still at large or been caught, we don't know at the moment. >> and we know they've been trying to evacuate that area behind you. even using boats in some cases? >> reporter: yeah, well, police are using every means necessary to evacuate all the people who are still around in the area, including the royal naval lifeboats to get these people out. when we arrived here, we saw them evacuating people with their hands on their heads, basically, you know, so that they can assure them that they are not part of the attackers. so, they're using whatever means necessary to evacuate people

from that area. >> our producer at the site of the first attack. thank you for your reporting. abc chief justice correspondent pierre thomas joining us live by phone. pierre, that suicide bombing in manchester, less than two weeks ago, where 22 people died and tonight, this in london. >> reporter: you saw that attack in manchester, you've seen truck bombings, you've seen the attacks in paris, also, the attack in germany involving a big truck running over people. so, they are in the midst of a bit of a siege here. it is more evidence that great britain, right now, has a serious problem with potential radicals in their country. >> and pierre, any time a major attack like this happens overseas, especially to a country that is an ally to the u.s., law enforcement here take precautions. tonight, we understand some instructions from the u.s.

embassy in london? >> reporter: yes, they're telling the people in london, u.s. citizens, to stay in shelter, monitor the local police and media and to do as told, that this is an ongoing situation, that it''s a dangerous situation, and here at home, the national security council has briefed the president, he's been made aware of the situation. and then, in new york, some major cities, they're stepping up a show of force, again, no specific information about anything here in the u.s., but they're trying to alert people to be on the lookout for anything unusual. >> our major cities taking precautions. pierre, thank you so much. let's head to the white house now. we're told the president is monitoring the situation. abc's david wright joining us now from the white house. david? >> reporter: good evening, tom. the president's national security team is keeping him abreast of developments in london, and clearly, he's watching the news, as well. tonight, he tweeted "whatever the u.s. can do to help out in london and the uk, we will be there. we are with you, god bless."

and shortly before that, the president seemed to jump to the conclusion that this was, indeed, a terrorist attack. he's using the chaotic situation in london as a moment to promote his targeted travel ban from six muslim countries. that controversial executive order bogged down in the courts since the president introduced it. well, just this week, the justice department appealed to the u.s. supreme court and tonight, with london in mind, the president tweeted, "we need to be smart, vigilant and tough. we need the courts to give us back our rights. we need the travel ban as an extra level of safety." that gives you a sense of where he plans to take this politically. the fight against it here, already a big theme for this presidency. you remember that in the wake of the attack in manchester, he called the perpetrators "evil losers." tom? >> and david, this attack coming in the middle of a campaign right now in the uk. prime minister theresa may leaving the campaign trail to address this terror attack. >> reporter: that's right.

and it's not the first time that the campaign has been suspended. british campaigns much shorter than american ones. this one, between two leaders who are relatively untested. prime minister theresa may and labor leader jeremy corbyn. it's generally thought that an attack such as this and the worries about it play to the tory party strengths, though, tom. >> david wright for us reporting from the white house. david, thank you. now, to another breaking headline involving politics. the major concession by president trump on climate change. he called eed it on more than occasion a 40ehoax. the dramatic switch coming on the heels of global criticism of the president's decision to pull out of the paris climate accord. abc's gloria riviera reports. >> reporter: tonight, after ridiculing climate change on the campaign trail -- >> so, obama is talking about all of this with the global warming and that -- a lot of it is a hoax. >> reporter: president trump's administration making a stunning reversal.

>> president trump believes the climate is changing and he believes pollutants are part of that equation. so, that is the fact. >> reporter: just a day ago, the head of the epa couldn't respond to a direct question. >> yes or no. does the president believe that climate change is real and a threat to the united states? >> you know, what's interesting about all the discussions we had through the last several weeks have been focused on one singular issue -- is paris good or not for this country? >> reporter: since trump pulled out of the paris accord, at least 80 mayors and 100 business leaders pledging to stay the course. >> and we will meet our targets. >> reporter: former new york city mayor michael bloomberg meeting with france's president macron, pledging $15 million of his own money. trump is promising to create a better deal. >> we will see if we can make a deal that's fair. >> reporter: ambassador to the united nations nikki haley offering further reassurance. >> just because we got out of a club doesn't mean that we don't care about the environment. >> reporter: trump supporters today rallying in front of the white house. so, for you, this exit, this was

cause for, safe to say, celebration? >> yes. well, there's a lot to be done. what's going on is not good for us right now. and, you know, obama had no right to just go ahead and sign it. >> reporter: getting out of the paris agreement takes time. in fact, president trump is likely stuck with current obligations until the year 2020. tom? >> gloria riviera for us tonight. gloria, thank you. and of course, much more on all of this tomorrow on "this week" with epa administrator scott pruitt, former vice president al gore and former national security adviser susan rice. and we're learning more tonight about the deadly casino rampage in the philippines that killed more than three dozen people. this chilling new video caught on security cameras, taking us inside that attack as it unfolded. the gunman, you see him there, entering the casino and later setting fire to gaming tables. stealing $2 million in chips. and getting into a shootout with police. the man later killing himself. and next, to the growing outrage here at home over the racial slur on a live television show.

talk show host bill maher using a derogatory, highly charged racial expression in conversation with a republican senator, ben sasse of nebraska. now, that senator facing heat for what he didn't say. maher's apology. the hbo network weighing in, as the calls to fire him are growing. here's abc's ron claiborne. >> reporter: tonight, the aftershocks of the racial slur said on live tv. in the middle of a seemingly harmless exchange between bill maher and nebraska senator ben sasse. >> i've got to get to nebraska more. >> you're welcome. we'd love to have you work in the fields with us. >> work in the fields? >> that's part of -- >> senator. i'm a house [ bleep ]. no, it's a joke. >> reporter: a torrent of criticism was unleashed at the comedian, whose brand is being politically acerbic and outrageous. deray mckesson, a black lives matter activist, tweeting, "bill maher has got to go. there's no explanations that

make this acceptable." tara sutmeyer, a political analyst, is a frequent guest on maher's shows. >> i think it was an unfortunate remark that he thought would be a funny joke that went wrong on the fly. and it was inappropriate. and i thought to myself, oh, my goodness, did he just say that? >> reporter: hbo rebroadcast the show before pulling it from the air. in a statement, the cable network said, "bill maher's comment last night was completely inexcusable and tasteless." and today, from sasse, a republican who, in the past, has criticized some of president trump's more incendiary tweets, he said he now wishes he would have said, "hold up. why do you think it's okay to use that word?" maher releasing this written statement of apology -- "friday nights are always my worst night of sleep, because i'm up reflecting on the things i should or shouldn't have said on my live show. last night was a particularly long night as i regret the word i used in the banter of a live moment. the word was offensive and i regret saying it and am very sorry." >> ron claiborne joins us live

now. and bill maher apologizing there, but this is not the first time he's said something controversial on the air. the last time, he got fired for it. >> reporter: back in 2001, he said that u.s. military strikes against terrorists in afghanistan were cowardly. his show was canceled nine months later. so far, hbo condemning his words friday night, but standing by him in terms of not suspending him or firing him yet, tom. >> yeah, a lot of people talking about this story earlier today. all right, ron, thank you so much. next, to that wild shootout at a gas station in texas. three officers wounded when a gunman opened fire. drivers desperate to get away. abc's eva pilgrim picks up the story with the late details. >> reporter: a barrage of bullets flying as a manhunt for a murder suspect ends in that terrifying and deadly scene. bystanders running for cover inside a convenience store, as gun shots rang out in laredo, texas, late friday afternoon. police saying 55-year-old

continue to see police vehicles and ambulances heading that way. but right now, this perimeter has been established and while they have not cleared the situation, it does seem far more under control than the panic horrifying moments that you are witnessing there. as far as what this means after manchester, westminster bridge in march, this is something that unfortunately londoners have grown used to. they have a stiff upper lip. they are defiant in the face of terror. but there is only so much sorrow that a country can take, and only so much rage. at some point, citizens in a democracy will want the government to keep them safe, or they will change the government. tom? >> terry moran with some perspective after this latest attack there in london. terry, thank you. and thank you so much for watching. i'm tom llamas in new york. stay tuned for the latest on the london terror attacks.
