learn how you can help at girlup.org. the united states and great britain have long been allies in the war on terror, but now a side battle has broken out pitting president trump against the mayor of london. the president fired the first shot after the saturday night terror attack on london bridge in which three attackers killed seven people before the police killed them. we have a series of reports tonight, beginning with our chief white house correspondent major garrett. >> we aren't going to allow anybody, whether it's donald trump or anybody else to divide our communities. >> reporter: london's first muslim mayor, sadiq khan rebuffed president trump's criticism. "at least 7 dead and 48 wounded in terror attack and mayor of london says there is no reason to be alarmed?" mr. trump wrote hours after the carnage. this is what khan actually said --

>> londoners will see an increased police presence today and over the course of the next few days. no reason to be alarmed. >> reporter: initially, khan said he was too busy to respond to the president's ill informed tweet, prompting mr. trump to write, "pathetic excuse by london mayor sadiq khan who had to think fast on his no reason to be alarmed statement." hours after the attack, president trump also renewed his call for a travel ban for from certain majority muslim countries. the president faulted the justice department which reports to him for pushing a watered down second version of the ban, which like the first, has been blocked by federal courts. he also said he would call the executive order what it is, a travel ban, directly contradicting members of his senior staff. >> first of all, it's not a travel ban. >> reporter: george conway, a trump ally and husband of counselor kellyanne conway said on twitter the president's tweet, quote, seriously

undermine administration agenda. and neal katyal, the attorney fighting the ban in federal court, wrote of mr. trump's tweets, "we don't need the help, but we'll take it." >> it is really very sad as to what's going on throughout the world with terror. >> reporter: this is the second time in a week the president's hasty response has caused controversy. last week mr. trump concluded an attack inside a filipino casino was terrorism. it turned out later to be a bungled robbery. h.w. brand studies presidential rhetoric at the university of texas. >> one of the things that makes a president sort of seem presidential is the kind of reserve that usually comes with the office. and president trump has decided to abandon that reserve. >> reporter: some of the president's top advisers are more careful with their words. after news of the london attacks broke, defense secretary james mattis responding to reporters' questions said, "i like learning about something before i talk."

i'm elizabeth palmer. today londoners were still struggling to take in the cruelty and the madness of saturday's attacks. eight minutes after it began, it was over. the three terrorists wearing fake suicide belts shot dead by police. but in their wake, they left mayhem and a trail of victims maimed in their stabbing spree. >> you keep going. you keep going! >> reporter: other victims were crushed by the attackers' van on london bridge. imagine the shock and the terror of people walking across this bridge on saturday night when they realized the van was hurtling toward them at 50 miles an hour. the driver determined to hurt or kill as many people as he could. brad myers, on vacation from florida, had a narrow escape. after taking a selfie on the bridge, he walked away, and then heard the van mount the sidewalk. here is the photo he took

afterwards, bodies strewn across the road. >> i do think that everyone needs to see what is going on and what we're up against. >> reporter: all those who gathered at a vigil today know they're probably up against even more terrorists with london in their sights. but led by the city's muslim mayor, sadiq khan, they stand determined to face them down. >> i want to send a clear message to the sick and evil extremists who commit these hideous crimes. we will defeat you. you will not win. >> reporter: scott, mayor sadiq khan was asked whether president trump would be welcome on a visit here. he said, "i don't think we should roll out the red carpet in circumstances where his policies are against everything we stand for." >> liz palmer at london bridge tonight.

mountain gorillas are one of the most endangered animals in the world, with fewer than one thousand left in the wild. but now their numbers are rising, thanks in large part to a group of veterinarians called gorilla doctors. the team works across a vast african rain forest spanning three countries -- rwanda, uganda and the democratic republic of congo. when lara logan joined them for a story on "60 minutes," the doctors were trying to free a gorilla caught in poacher's trap. >> you've got a 10 cc? >> reporter: with the wounded gorilla close by, the gorila doctors prepped their medical gear on the floor of the forest. >> martin, if you could get betadine ready too. >> reporter: finding her had not been easy, and they didn't want to lose this chance to treat her. >> and you're going use that volume. >> reporter: dr. mike cranfield

has been running gorilla doctors for 18 years. dr. eddie kambale is his right hand. and dr. martin one of his newest field veterinarians. >> reporter: what is the plan right now? >> so right now eddie is getting the anesthetic ready. because it's a snare, we know we're going to do a knock-down. he'll dart the first chance he has. >> reporter: are you a good shot, eddie? >> he is an excellent shot. >> reporter: eddie grabbed his dart gun that was loaded with anesthetic and went with the trackers to find the wounded female, who hurt herself when she picked up a snare poachers had set for a smaller animal. they had to cut a path through the forest as they went. she was with her group, and they were moving fast. thick vegetation gave way to a clearing. where they spotted her. then eddie stepped forward and prepared to take his shot.

as soon as it hit, she took off. and the team followed. they knew she had to be close. it was an unforgettable sight. now they had less than 40 minutes to assess her wound and treat it before the anesthetic wore off. they call this an intervention. >> eddie and i and martin have done probably 15 interventions together. it's a team. it's always the team. we have some of the most important patients in the world, right? if something doesn't go right, basically, you can almost count

on it being known almost worldwide. >> reporter: how would you rate the quality of your work as an organization? >> i think it's very good. >> reporter: when they're not doing emergency interventions, mike said his doctors are out making house calls. and in the ten days we spent with them, we went on a few, this one in the drc, where eddie and martin are based. >> activity. >> all the signs are normal. so that means she is still healthy. >> active, moving. she is using all limbs. i can just see she is breathing. i can try to count the breathing rates like now, you see? one. you can see how the abdomen is raising. two. three. >> reporter: these gorillas live in virunga, the oldest national

park in africa. and from the air, some of the most forbidding landscape you'll ever see. when the doctors began working here, the mountain gorillas were almost extinct. today they're the only population of great apes that's growing. >> they're increasing at 4% a year, which is about the maximum that they could. that's as fast as the human population is growing on the face of the earth. and veterinarians are credited with 50% of that growth, or 2% a year. >> reporter: you're talking about gorilla doctor, your veterinarians and you. >> we're the only veterinarians that are working on the gorillas in the clinical sense. >> reporter: over the years, mike told us he has had a few run-ins with his patients. >> he came flying towards me for about 30 years and just punched me right in the face. >> reporter: did it hurt? >> a little bit. >> reporter: this is umoja,

michael's miracle baby. part of her intestines were hanging out of her body when the gorilla doctors got to her. now eight years later, mike wanted us to meet her, which meant hiking through a bamboo forest, layers of vegetation and up to more than 9,000 feet. there on the steep volcanic slopes in northern rwanda, we found umoja's family. and here she is, a new mother, her baby boy only a month old. >> umoja is probably the most spectacular case that we've ever had. and that brought a lot of pride for gorilla doctors. >> reporter: so it's not just the animal that you save, it's the future generations? >> correct. you're actually influencing not one life, but multiple lives. >> reporter: in rwanda where we met one of mike's senior veterinarians, the mountain gorillas have become a national

symbol. he was 14 when his country was torn apart by genocide in 1994. more than 800,000 people were slaughtered in 100 days. so what do you remember of the genocide? >> darkness in the whole country. at that age, you know, you don't have much thinking, but you can see that this is over. the whole country is over. >> reporter: in 22 years, rwanda has risen from the ashes, and the gorillas are at the center of that transformation. close to 30,000 tourists come every year for the gorillas, and tourism is the biggest source of foreign income for this tiny nation. >> the connection makes everybody feel, okay, these guys are very important to us. >> reporter: these gorillas are. >> these gorillas are important us to. everyone feels that. >> reporter: mike, who works with the uc davis wildlife health center, was at the

gorilla doctors headquarters in rwanda when he got the call about that wounded gorilla in the drc. >> oh, dear. okay. and how long has the snare been on? >> reporter: before long, we were rushing for the border. from the moment you get that phone call, is there a pressure to move as fast as you can? >> yeah, speed. speed is everything. 24 hours can make a difference to having function, full function in the hand. >> reporter: that's kind of tough here sometimes. >> it is. >> reporter: because speed matters. but to get there you have to take the slow boat. >> right. >> reporter: dr. eddie was waiting for us at the slow boat on the other side of the border on the shores of lake kivu. amidst the crowd and the chaos and struggling to hold on to our gear, we boarded with minutes to spare and settled in for the long journey. a 12-hour odyssey across one of africa's great lakes. we woke as the sun was rising and pulled into the harbor with

the hustle and bustle of the early morning. and then we still had to get to the animal. >> that's -- that's sometimes the most difficult part. >> reporter: a bumpy ride and a broken bridge took us to the edge of the national park. from here we went on foot, hiking deep into one of the largest forests in the drc. every time we went down, we have to come back up. and the hills were steep. we walked and walked, with no sign of the gorillas, stumbling and falling into the night. >> not easy to find the trail at night. >> it was hard walk manage the dark. >> yeah. >> reporter: even for you? but that wasn't normal. >> that was not normal. it was really hard.

>> reporter: with worn feet and low expectations, we tried again the next day. this time the trackers got lucky and led us right to them. >> and you can watch the full report on our website, cbsnews.com and click on "60 minutes." we'll be right back.
