Thank you. And again, abc news has just confirmed the suspect in the shooting has been killed by police. Next, the race for 2016. New poll numbers revealing just how close the contest has become. The abc News Washington post poll, out today, showing donald trump with a twopoint advantage over Hillary Clinton among registered voters. An 11point swing since march. The neck and neck polling coming as theyre trading tough talk about guns. And Bernie Sanders says dont count him out yet. Heres david wright. Reporter donald trump says hes coming up fast, according to the new poll. The brash billionaire closing a ninepoint gap to overtake Hillary Clinton by a nose. I call her crooked hillary. Reporter they squared off this weekend over the issue of guns. Hes talking about more guns in our schools, more hatred and division in our streets. I dont want to have guns in classrooms, although in some cases, some teachers should have guns. Reporter today, trump took the new numbers in stride. I think well do even better than that. Reporter the new poll shows trump and clinton to be the most unpopular candidates ever to run. More than twothirds of voters have an unfavorable view of broet. Thats why democrat Bernie Sanders told george hes sticking around. I dont want to see the American People voting for the lesser of two evils. Reporter Hillary Clinton has already crowned herself. I am going to be the nominee. Senator clinton is jumping the gun a little bit. Reporter last night, the Season Finale of snl imagined sanders as the guy hanging out at the bar too long. Im sorry, but the night is over. No, no, its not over. Its not over until i say its over. Reporter sanders insists he still has a pathway to victory, and hes made it clear he plans to stay in the race through the end of primary season. In about three weeks time. According to the new poll, he has the most positive rating of the three of them. Tom . Thank you. And next to the deepening mystery around egyptair flight 804. More pieces of debris discovered today, but still no sign of the black boxs. That could help determine where ch why the plane disappeared from radar. And whether it was aircraft malfunction or terrorism that could be to blame. Heres matt gutman. Reporter tonight as debris and personal belongings are being scooped off surface of the mediterranean, the search begins beneath it. France moving this sub hunting ship into place tonight. Its mission now to locate Something Else in the depths, the wreckage of flight 804. And egypts president saying his navy is deploying a sub, capable of scanning the depths at up to 10,000 feet. How big is the search area . Around 60something kilometers. Reporter a radius of 66 kilometers, means the search area is massive. Over 5,000 square miles, or about the size of the state of connecticut. Today the pentagon announcing its p3 planes flying round the clock sorties over the area, using those sophisticated sensors, have so far detected 100 pieces of debris. Those warped seats, perforated handbags and smashed paneling suggest the violence with which the plane broke apart. During the final minutes of the flight, multiple smoke sensors going off. Including in the bathroom and just below the cockpit. It could indicate catastrophic mechanical error, or terrorism. In my view, its highly likely because of the amount of effort that isis and al qaeda have put, over the last few years, into trying to develop an undetectable bomb. Weve examined the overhead intelligent and manifests. We havent come up with any hard evidence of terrorism as of yet. Reporter the voice talking to air traffic control, eerily cheerful. Tonight hundreds gathered as his funeral. The human remains will be the number one priority. Reporter what everybody wants are answers. Since not a single terrorist group has claimed responsibility, its possible the only clues may be with the black boxes, and there are fewer than four weeks to retrieve them before they go silent. Thank you. I want to bring in steve ganyard. We just heard that no terrorist group has claimed responsibility. Is it too early to rule that out . Well, there is good evidence that points to a mechanical problem, but we still need to consider terror. If it is a mechanical catastrophe, how surprising is this for one of the most popular jet liners out there . Its very surprising. Its a popular airliner, very reliable. And even the mechanical theory doesnt exactly fit. You shouldnt have a fire in the nose of the airplane that brings it down. So many questions still. Steve, thank you. And president obama has arrived in vietnam for an historic visit. Hes the third president to visit vietnam. Topping the agenda, shared concerns over china and security. And now to the air strike that is believed to have taken down a top terrorist leader. The pentagon says he was at the helm of thousands of attacks. Mary bruce with details of the the strike, and the new pictures coming in. Reporter flames and this charred car are all thats left after a u. S. Airstrike targets Afghan Taliban leader mullah mansour. Its around 2 30 p. M. Saturday in pakistan. U. S. Officials say mansour is traveling in a remote region near the Afghan Border when multiple drones flown by u. S. Special Operations Forces strike. Mansour and a companion, riding in that car, are believed to be killed. President obama, traveling to asia on air force one, is updated by his National Security team. The strike, authorized by the president , is the most aggressive u. S. Military action in pakistan since the raid that killed osama bin laden. U. S. Officials say mansour has been actively plotting to attack u. S. Forces in afghanistan. Mansour posed a continuing, imminent threat. Reporter since taking over last year, mansour has proven himself a brutal leader. At his direction, the taliban killing thousands. Refusing to join peace talks. But tonight, u. S. Officials are hopeful this could pave the way for a more moderate leader. Tom, while this is a window of opportunity, its a narrow one. Mansours death will now likely welcome a power struggle, and whoever wins that battle could determine the future of the afghan peace process. Tom . Mary, thank you. Meantime in iraq, residents of the city of fallujah asked to leave because of an impending strike. Next tonight, drama and danger at the worlds tallest peak. A pair of climbers are dead, and two more are reportedly missing on mt. Everest. Heres lauren lyster. Reporter a desperate search is under way tonight for two hikers missing on the roof of the world. 30 more suffering severe illness from the dangerous climb. This after eric arnold and maria strydon died from altitude sickness after reaching the worlds tallest peak. Strydon climbing with her husband. A climber can develop altitude sickness anywhere on everest, and it can come on suddenly and with no warning. Reporter arnold was a professional climber who was attempting everest for the fifth time. He survived this avalanche last year that claimed 18 lives, and shut down the mountain. Over 250 people have died trying to summit everest, but more people than ever are trying to ascend the mountain. Some of them without the proper training. The problem with everest isnt necessarily the number of climbers, its the experience. They feel qualified to take the highest mountain in the world. Reporter at nearly 30 thousand feet, even the smallest problems can turn tragic. Next, a warning tonight about the zika virus coming to america. This, according to dr. Anthony falchi. Saying that mosquitoes may begin infecting people in the states. More than 500 americans already have the virus, but those are travelrelated. Now to a monster super cell traveling across kansas.

And with that, the tornado watch extends across the plains this evening. Into tomorrow, the threat will expand all the way into minneapolis and sioux city. And watch out for damaging winds, hail, and isolated tornadoes. Instability still in for the holiday weekend. Now to a man recovering after a bear attacked him, biting into his head. Charging so fast, he had no choice but to fight back. Heres aditi roy. Reporter tonight, a miracle in the wild. After an alaskan man comes facetoface with a full grown, brown bear. It was like looking the devil right in the face. Reporter kenny steck encountered the predator while he was filling up Water Bottles during a hiking trip with family in southeastern alaska. The experienced outdoorsman said he had left his bear repellant back at camp when the massive animal came charging at him. When steck lifted his leg up to protect himself, the bear clawed it. I remember thinking, this thing is going to kill me. Reporter he tried yelling, but he says the bear crushed his shoulder blade, and put stecks head in his mouth. One of his fangs had gone right into his head. I remember the sound of it breathing, snarling. Reporter then, suddenly, the bear just let go and ran away. His wife and three other family members on the trip, nurses. Who were able to treat his wounds right away. For some reason it wasnt my time to die. Reporter looking back, steck tells me it all happened so fast he might not have even had to time to reach for that bear spray. He just thinks he got incredibly lucky. Tom . Aditi, thank you.
