Well see more of that later, but these celebrations are well have more on that later, but well begin with chaos on the turkey syria border as turkey continues its attacks on the kurds in Northern Syria, and new reports of a mass escape by isis followers, and as the situation unravels, the u. S. Saying it will pull 1,000 troops out of the region. Lets go right to ian pannell in the region with the latest. Good morning, ian. Reporter take a look behind me. These are some of the graves of the thousands of men and women who fought against isis, and now their comrades out there on the front line say they feel they have been abandoned. This morning, chaos and bloodshed in syria as President Trump orders all remaining u. S. Forces to leave the north of the country. Roughly 1,000 troops gearing up to head to the border. This as a senior u. S. Official tells abc mass atrocities are being committed against the Kurdish People at the hands of turkishbacked militias. Some isis fighters in prison taking advantage of the mayhem reportedly escaping making u. S. Positions ever more vulnerable. Turkish forces hammering americas kurdish allies. Some exal qaeda leaving a trail of displacement, destruction and death. Abc news obtaining exclusive footage showing the battle from the turkish side. These troops fighting with one of the turkishsupported militias. In just a week hundreds reported dead. Around the world condemnation growing as the turkish militias execute people on the roadside. Among those slain, one leading kurdish political leader apparently dragged from her car and shot in the head. This is a war crime if verified. This video obtained by abc news appears to show the fury of the turkish attack on the border town. This is one of many hospitals throughout this area that are treating the wounded, mainly civilians who have been caught in the middle of this conflict not of their own choosing. Sara was among them, just 8 years old playing in the street when a turkish shell landed. Her 13yearold brother mohamed killed. The United Nations estimates at least 130,000 people have been displaced by the fighting and that number likely to grow. President trumps move to pull out troops condemned by members of his own party. Leaving an ally behind, abandoning people that we, frankly, told that we would be with is disheartening, depressing, frankly its weak. Reporter a few days ago kurdish commanders gave america an option either back us in our battle with turkey or well turn to someone else. And thats exactly what is happening now. American troops on the way out and syrian troops backed by russia rolling in this direction. Now, if they face off against turkey, then president erdogan will have a much bigger battle on his hands than he ever gambled for. Robin . Escalating. All right, ian, thank you. Amy. Secretary of defense mark esper making it official on sunday, the u. S. Plans to pull all 1,000 of its troops out of Northern Syria. Lets bring in chief Global Affairs correspondent Martha Raddatz now, and martha, we just saw the situation on the ground already dire. What happens when these remaining u. S. Troops leave the area . Reporter amy, the ramifications are enormous. You could have fullon war there with thousands more isis fighters and their families escaping during the chaos and eventually reemerging and you are certain to have more of those horrific scenes that ian just showed us mass atrocities, executions. There are many special Operations Forces who see this as shameful to abandon the kurds who helped the u. S. Fight isis losing thousands of their soldiers in the process. Those kurdish allies now making a deal as ian said with the Syrian Regime which is an enemy of the u. S. And backed by russia. The leader of those forces writing today that if we have to choose between compromise and genocide, we will choose our people. This is a major shift and means the u. S. Is ceding any influence there to russia, iran and the assad regime. As for our own forces there, a u. S. Official says the president has given them 30 days to get out of Northern Syria, but their positions are becoming more and more vulnerable, and they are consolidating to get out as soon as possible. Its important to say it is not that they think u. S. Forces should be involved in endless wars, but rather the abrupt decision made by the president in that phone call with turkeys president which was the trigger for all of this. There are people at the pentagon and state department, amy, who are simply furious about this. And martha, you mentioned those escaped isis prisoners. Last night, we saw President Trump tweeting that the highvalue detainees have all been secured. Is that verifiable . Reporter well, the president said the u. Shas the worst of the isis prisoners, but that is not accurate. A u. S. Official says they were only able to transfer two of them to u. S. Military custody, but in that chaos, dozens more set to testify this week against the wishes of the white house. Turning now to mary bruce. Good morning, mary. Reporter good morning, t. J. With congress now back in session and this impeachment inquiry deepening lawmakers are set to hear this week from several key witnesses despite the Trump Administrations efforts to block them. Including u. S. Ambassador to the eu gordon sondland. Now, he is reportedly expected to testify that a text message he sent saying there was no quid pro quo between the president and ukraine was dictated by trump himself, that he does not know if the president was telling the truth or not. Now, trump and his allies, of course, have been defending the president s push for ukraine to investigate his political rivals by insisting that there is no quid pro quo. That the president was not withholding military aid as a condition for ukraine to investigate. Well, the ambassadors testimony here this week, t. J. , could poke a big hole in that argument. Lets turn to joe biden for a moment. A lot of people will say he was a little slow to call for the impeachment of the president but he certainly is ramping up his attacks on trump now and this happens as bidens son is making a big announcement. Reporter yeah, t. J. The president has been relentlessly attacking the former Vice President , and now it seems joe biden is trying to lay down some ethical markers. He announced over the weekend that if elected, no one in his family will do business with Foreign Companies or governments. And says they will not be sitting in on cabinet meetings, a not so subtle jab at President Trump and his children and all of this, though, of course, comes as the former Vice President s son hunter biden has announced he is stepping down from the board of a chinesebacked firm and his work in china and ukraine has been a top attack line for President Trump against joe biden even though there has been no evidence of wrongdoing by hunter biden, t. J. Mary bruce for us in washington, thank you so much. Speaking of hunter biden you recently spent time with him. Thats right, robin. I spent the entire saturday with hunter biden, the son of 2020 president ial candidate, and former vp, joe biden. We spoke there at his home in los angeles for an exclusive interview and no questions were offlimits. We talked as you might imagine in depth about his business dealings in ukraine, china and his reaction to President Trumps rally and tweets where we hear him chanting and writing, where is hunter, lock him up. It is an emotional and candid interview and you can see it starting tomorrow on gma. So much to talk to him about. Indeed. All right, amy, thank you. But now to the desperate effort to find a missing worker trapped under the rubble of that Hard Rock Hotel in new orleans. At least two people were killed. Dozens injured after a crane fell during construction. Victor oquendo has more in new orleans this morning. Good morning, victor. Reporter good morning, robin. This is a race against time. Were just a block away from the site of the collapse. You can see the top floors here just mangled. Right now the focus is on finding that missing construcon worker trapped inside. Oh, my god. Reporter this was the moment the new Hard Rock Hotel and a crane came crashing down in new orleans. Killing two people, injuring 30 more. There is reported to be a Building Collapse at the hard rock cafe. The incident right here looks like the top four floors are hanging down. Reporter people running for their lives as steel and concrete fell from the sky amid a growing cloud of dust and debris. All those guys running. Yeah. Oh, dear god. Reporter watch the people riding this trolley narrowly escaping. More than 100 construction workers on site at the time of the collapse saturday morning. One worker still unaccounted for. Search and rescue continues to remain our top priority at this time. Reporter this drone video shows the extensive destruction from above, several of the top floors of the structure reduced to rubble. Crews working round the clock sunday stabilizing the building before rescue teams could safely search for the missing worker. New orleans mayor vowing to determine the cause of this deadly collapse. After a search and rescue, it will then shift into a full investigation mode and we will be relentless in those efforts moving forward. Reporter the challenge for search and rescue teams has been the structures instability. They brought in all kinds of equipment to help like that big black crane right there. Theyve flown in engineers as well. They are still in rescue mode here. Amy. We certainly are thinking of all of them. Thank you, victor. Now to the outrage and the search for answers after a white Police Officer shot and killed a black woman in her own home through her bedroom window. Abcs marcus moore has the story. [ crowd chanting ] reporter overnight, protesters flooding the streets. No justice, no peace. Were tired of this. Reporter anger rising following the shooting death of 28yearold Atatiana Jefferson killed in her home by a ft. Worth Police Officer. Im calling about my neighbor. Reporter the incident sparked by a phone call made by a concerned neighbor. In the newly released audio, her neighbor tells police he noticed her door was open at 2 24 in the morning, and asked for a welfare check. I havent seen anybody moving around and its not normal for them to have both of t he doors open at this time of the night. Do you know if anyone is inside . Im not sure, both of the cars are there. Reporter the dispatcher sent officers to her home. This body cam video shows the moment the encounter turns deadly. The responding officer is not heard identifying himself as he approaches jeffersons bedroom window and begins shouting commands. Put your hands up. Show me your hands. Reporter within moments he fires one deadly shot through the window. It was less than a second. I had an expert slow it down. Its. 6 seconds between the command and the shot. There was no time for them to perceive a threat from the weapon, no time for her to respond. It was reckless deadly behavior. Reporter according to her family, she was playing video games with her nephew when that shot was fired. That neighbor who made that welfare call is speaking out. When i made that 911 emergency call, i didnt say it was a burglary, i didnt say it was fighting across the street. I didnt say anything that would make them think they needed to have a gun. All they needed to do was knock on the door and ring the doorbell. Reporter the case now igniting a public outcry. What the officer observed and why he did not announce police will be addressed as the investigation continues. Reporter and the officer who fired that shot is expected to speak with internal affairs some time today and family members say jefferson was a premed graduate from Xavier University in louisiana, and had returned home to take care of her sick mother. Beyond tragic. Beyond tragic. Marcus, thank you. Now to simone biles and any doubt that she is the greatest gymnast of all time was put to rest. Biles is now the winner of more medals at the World Championships than anyone ever. Adrienne bankert is here with that. Good morning, adrienne. Reporter yes, lets have some good news and talk about it. Simone biles now being called unbeatable by some. Shes known for her fierce focus, addictive energy, twists and flips that few others, if any, can pull off. With an unrivaled medal count, now many say shes the greatest of all time. She could barely catch her breath. Simone biles now the most decorated gymnast, male or female, in World Championship history standing just 48 tall, biles is a formidable giant in the world of sports. With her parents cheering her on, the superstar delivered this historymaking performance in germany on sunday, her mom overcome with emotion. Ah, in tears. Reporter the u. S.

You know who won again . The saints. Look at that mile. Look at that smile. Reporter another victory. You walked right into that. Oh, yes, yes, yes, defeating jacksonville on sunday.

Divine intervention but the response to the popes tweet, priceless. Priceless. And it worked. Maybe unprecedented, too. It did. Prayers are answered, robin. All the time.

And they are now demanding answers. Also this morning, the serial stowaway. A woman known for sneaking onto planes without tickets arrested again. Well talk about that but first to ginger. Ginger. Saints country about to get rain, robin. We have to watch for that. Along this week, this warm front will lift north so from louisiana through mississippi all the way over to South Carolina actually. Were going to end up with two to four inches, some of those red spots in arkansas, mississippi, South Carolina and georgia could end up with locally more than five inches. So lets go ahead and focus on mississippi. Just because tonight through early tomorrow i think it could potentially be a dangerous situation as some of this rain comes through. There are some alerts up for central mississippi including macomb, meridian, hattiesburg and jackson. Anywhere from interstate 20 south to 84. Thats where we could end up with 2 inches to 4 inches of rain. That doesnt sound like a lot.
