In the days other news russian jets resumed heavy bombing of aleppo, syria, after days of relative calm. At least 16 people were killed there today, in air strikes on rebelheld neighborhoods. Recent drone footage showed the scale of the devastation in eastern parts of the city. Meanwhile, french president Francois Hollande criticized moscows actions in syria. Just as russian president Vladimir Putin canceled a trip to paris. translated i think it is necessary to have dialogue with russia. But it must be firm and frank otherwise it has no role to play, otherwise its just a charade. So im ready to meet president putin if we can make progress on peace, stop the bombings and implement a ceasefire. Sreenivasan in southern syria, rebels fired rockets at governmentheld areas. One hit a primary school, killing at least six people mostly children. Its been another long day for thousands of people coping with the aftermath of Hurricane Matthew. The u. S. Death toll rose to 30 today. Half of those deaths were in North Carolina. Meanwhile, president obama signed a disaster declaration for South Carolina.

Reporter main streets turned into waterways, as rescuers boarded boats and helicopters again today to search for people stranded in the deluge. Some 1,500 people became trapped in the town of lumberton, North Carolina when a river there began overflowing on sunday. This morning, North Carolina governor pat mccrory urged those who could, to leave, and fast. Get out, get out now. And right now were hearing you are putting not only your life at jeopardy, you are putting our Emergency Rescue teams in jeopardy. Reporter one new death in the state was not by water last night, state troopers shot and killed an armed man during a search and rescue mission. Governor mccrory would only say the shooting happened under very difficult circumstances. Flood waters continue to inundate towns like lumberton after Hurricane Matthew poured more than a foot of water on eastern North Carolina from the capital raleigh, south to fayetteville and beyond. Interstate 95 was still inundated and blocked off near the South Carolina border, severing the major northsouth route along the east coast for another day. Hundreds of other roads were flooded or damaged, leaving whole neighborhoods cut off. In moore county, residents were evacuated late last night as crews worked until morning to shore up a dam threatening to burst. Where the waters have receded, the damage is ruinous. Bob swilley piled up 400 sandbags to protect his fayetteville print shop from the waters all in vain. Saturday night this flooded over. You can see the damage here. It flooded over the road into the bottom of our building. Thats where all of our equipment is. What we need is immediate help. Reporter the scale of the destruction is still unclear as flooding continues, but thousands of homes have been damaged already. And half a million are still without power throughout the southeast.

For the pbs newshour, im william brangham. Sreenivasan in china, more than a thousand protesters demonstrated today outside the Defense Ministry in beijing. Many wore army uniforms, and stood for hours outside the ministry to denounce military downsizing, and problems with veterans pensions. Hundreds of police used buses and other vehicles to obstruct views of the protest. The World Health Organization called today for higher taxes on sugary drinks. Officials at the u. N.

The Dow Jones Industrial average plummeted 200 points to close at 18,128. The nasdaq fell nearly 82 points, and the s p 500 lost 27. Still to come on the newshour samsungs mounting smartphone troubles, a look at mustwin states for the president ial candidates, a country inundated with child refugees sends them to school, and much more. Sreenivasan its an eventful day and a humbling one for the electronic giant samsung, the Worlds Largest maker of smartphones. Today the Company Announced it is halting production of its beleaguered galaxy note 7 phone. Reports of the note 7 catching fire caused the company to issue a recall and then create replacement devices that were also found to be a fire risk. It comes coincidentally as a prolonged battle between apple and samsung over money, patents and the designs of those phones you use went before the u. S Supreme Court today. Jessi hempel is with backchannel, a web based platform that covers the tech world. Tell us a little bit about the issues surrounding this. Weve seen dribs and drabs of people saying, look at this burnedout battery, look at this burnedout shell. How long has this been going on . How serious it is . Well, its quite serious. Its really impossible to underestimate how serious this is for samsung. Its been a month and a half. You know, at first when the phones started catching fire, samsung acted decisively and immediately and got a lot of credit. They issued a recall. People went and returned their phone, and then the new phones started catching fire. Thats when it became a very serious problem for samsung. It suggests that we really cant trust the brand, and frankly, when people think about this, yeah, maybe theyll remember that its the Samsung Galaxy note 7, or maybe theyll just think about the brand name samsung. Sreenivasan thats a big company. They make everything from washers and dryers to lots of other bigger things, but how important is this . This is sort of the flagship phone, the one theyre supposed to be most proud of. This is their flagship phone. Its important for a couple reasons. First off, this was what they put forward to compete with apples new iphone. And quite frankly, it doesnt work. It will be a huge financial loss for the company. Now, its hard to say exactly how much, and it will be a while before we know, but ive seen estimates put it at between 4 and 5 billion. So its very important. Sreenivasan speaking of apple, theyre in the Supreme Court today. Whats their core disagreement between apple and samsung . You know, anybody who has watched samsung and apple ovr the last five years has seen this play out in ticktock, this ongoing fight between samsung and apple. Whats at issue today is no longer the question of did samsung coppy apple. Yes, everyone has agreed that samsung has copied apple. Its not a question of should samsung pay apple. Yes, the courts have agreed. Samsung already paid apple. What is at question now is how much money does samsung really owe apple. Now, the courts, the federal courts in california said according to the law, samsung owed the total profit on the phone that it ripped off pieces of the design from apple. Samsung at this point is saying, wait, hold on a minute, why should we pay total profit. Were raising objection overthree design elements. Surely we shouldnt have to pay the total profit for the phone just over three design elements. About deciding how much money either apple will continue to keep or if it would have to give it back . Thats right. And, you know, the reason why this matters, the reason why the Supreme Court would even decide to look at this right now is because it raises the questions, the importance of design to a product. And that, of course, is a big issue for Silicon Valley at large. And its been a very long time. I think 130 years since the courts took up this issue of patent, of design patent. It gets to the question of what is core to a product . What differentiates it in the market. You know, its funny. These three design elements, each on their own, they just dont seem that big. Theres the question of the rectangle shape of the face of the phone. Theres the question of the raised glass on the front of the phone, and then theres the question of the icons on the front of the phone. Now, if you think about all these things, right, they have become central to what we think of as not just an iphone at thisoint, but a smartphone. Apple says, hey, we get credit for that. We designed those. We own those. You owe us all of the money off the phones that ripped those off. Samsung says, wait a minute, you know, parallel to this is like a car and a cup holder in the car. Would you say that if i ripped off the design of a cup holder in the car that i should pay you the total profit on the entire car . Is that what differentiates it to the consumer . Sreenivasan jessi hempel from backchannel, thank you so much. Thank you. Sreenivasan since friday, the antisecrecy group wikileaks has been releasing emails that were hacked from the account of Hillary ClintonCampaign Chairman john podesta. The stolen messages detail how the campaign responded to important issues through the race for the white house. It is unclear who was behind this latest digital theft, but on friday the Obama Administration did blame russia for the hacking of the Democratic Party websites earlier this year, and attempts to breach state election systems, in order to influence the vote for president. Today, white house spokesman josh earnest said there will be a u. S. Response to the alleged russian hacking, he told reporters aboard air force one. With me now to sift through what all this means in both political and diplomatic terms are the newshours Margaret Warner and lisa desjardins. Lee centennial lisa, lets start with the emails. Right. This latest jump, so people can keep track, began on friday. These are about 2,000 emails, a little bit more, coming from Clinton Campaign manager john podesta. Big player in the clinton world for years. We see a standout note have s from a clinton 2013 speech to an italian bank. You may have seen that quote. In the speech that was referenced in the emails, which was purported to say, my dream is a hemispheric Common Market with open trade and open borders. Obviously thats raising a lot of questions in this year of very heated talk about trade and especially after clinton herself came out against one of the largest in history trade deals, the transpacific partnership. Thats probably the biggest headline thats come out of these email, but also they include a great deal of campaign tactics, including a 71page briefing, sort of research to some extent on burgoin. All exon bernie sanders. All of this was happening during that primary campaign. The Clinton Campaign is not confirming the authenticity of any of these emails. Its very important to say that wikileaks has posted these. We know they were hacked, so the authenticity is fair to question. The Clinton Campaign is saying this is from a state actor and this is obviously an illegal act in politics. Sreenivasan margaret, how did they discover this in the first place . Not only did they come out on wikileaks, this latest batch, but there have been two other sources, something called lucifer 2 and something called lucy leaks. And the u. S. Government, intelligence officials and also many cyber experts have been sure for at a 90 degree of certainty for months that two russian spy, cyber spy agencies, one tied to russian intelligence, one tied to Russian Military intelligence, had been behind these. These have been known for months. F. B. I. Director james comey did tell the congress, in fact, he said, were trying to determine just what mischief is up to in connection with our election. So the difference between the hacking and the leaking, and the russian m. O. , u. S. Officials believe, is they do the hacking, and then they give them to other to do the leaking. Sreenivasan lets talk about the timing, coincidence or not in an Election Year . Whats the political fallout . Well, the fallout first of all has not been related directly to the content of these emails. I think the worst fallout for Hillary Clinton is whenever the topic of emails come up. Whenever the idea that she and her strategists are doing things in secret that the public dont know about. The truth is there is no indication of any wrongdoing. This is typical Campaign Operations for the most part in these emails. You could say youre not good on style or insight or whatever, but there is no indication of wrongdoing. Instead the whole concept of emails and a shadowy clinton world is the problem, which they say is a shadow conspiracy. There are greater issues in that what these emails are doing is its changing how a political operative communicates, for example, i know sources now who will not communicate over email, who must communicate by phone. When our leaders arent able to talk to each other over the most common device they use, tha
