Commander in afghanistan said today American Forces violated the rules of engagement when they mistakenly bombed a hospital run by Doctors Without Borders last month. The airstrike in the Northern City of kunduz killed at least 30 civilians. More now from david martin. Reporter it was one of the worst accidents of the afghan war, and it was caused by what general John Campbell described as a perfect storm of mistakes, committed by Americas Elite Special operations forces. This was a tragic but avoidable accident caused primarily by human error. Reporter after nearly five days of nonstop fighting in the city of kunduz, american commandos were holed up in a Police Station with afghan troops. The afghans requested a strike on a nearby government building which had been taken over by taliban fighters. An ac130 gunship was called in commander. The gunship was given the coordinates of the government building, but its targeting system zeroed in on an open field instead. The air crew visually identified the closest structure that resembled the government building they were supposed to strike. They did not know it, but that building was in fact the hospital run by Doctors Without Borders. Before opening fire, the gunship provided the coordinates of the target to a command center at bagram airfield. The command center knew those coordinates belonged to the hospital, which was on a no strike list, but nobody put two and two together. The gunship opened fire. Someone from Doctors Without Borders called bagram to report the attack, but by the time the command center realized the mistake, the gunship had already ceased fire. All this happened at a time when the american combat role in afghanistan had supposedly ended, and under the new rules ground commander did not even have the authority to call in that strike. Some of the commanders involved in the strike have been relieved of their duties, and now face possible disciplinary action. Jim. David martin at the pentagon, thank you.

It reveals an underground city with electricity, plenty of food, and stacks of ammunition. All of this was built up during the year isis controlled sinjar. Kurdish forces retook the city two weeks ago. One of the two russian airmen shot down after venturing into turkish airspace yesterday was rescued today by syrian allies. The other was killed by the militants on the ground. The survivor denied turkeys claim that it gave repeated warnings before firing on the russian plane. He said he never heard one. Holly Williams Joins us now from istanbul. But for the time being at least it seems cooler heads are prevailing. Reporter thats right, jim. This looked like a very dangerous situation just 24 hours ago. We had an american nato ally shooting down a russian warplane after it allegedly strayed for just 17 seconds into turkish airspace. We had a dead russian pilot, and we had the russian president , vladimir putin, threatening serious consequences. Today, though, it is very clear that all of the players in this drama, including the u. S. And nato, want to avoid a conflict. The turkish president , tayyip erdogan, said today that he did not want to see an escalation and russia said that it would not wage war against turkey. So a crisis has been averted this time, but that doesnt solve the underlying problem which is the syrian civil war. The u. S. , russia, turkey, iran, and other countries have all taken sides in syrias war, and they are all now being drawn deeper and deeper into the conflict and perhaps closer to a conflict with each other. But for the time being no escalation. Holly williams reporting for us tonight from turkey. Thank you.

Reporter researchers at Boston University told us today that 88 of the 92 former nfl players they examined suffered from cte, thats 96 . Dr. Robert cantu heads the Boston Universitys cte center. Sometimes it can be one horrific single injury, but mostly its repetitive head injuries. Reporter both the new york giants and the nfl said today they appreciate the gifford familys efforts to help advance understanding of cte. Jim, the nfl said it is not waiting for science but is working now to improve the safety of the game. Anna werner, thank you very much. Still ahead is thanksgiving eve. Let the shopping begin.

In order to keep up, amazon has hired 100,000 extra Seasonal Workers. One of those is 20yearold zahmir ibezim, a College Student looking to save up money before he heads back to school in january. The money you make here, what are you going to use it for . Im going to use it to pay back school. So this is to make money to pay off some loans . Yes. Amazons hiring is a 25 increase from last year but they are the exception. Overall, Holiday Hiring is expected to be just slightly higher than last season. Fedex is adding 55,000 workers, roughly 5 more than 2014. Major retailers like macys and target will add the same amount of workers as last year. Andrew challenger is the Vice President of the Employment Firm challenger, gray, and christmas. Because so much of the Holiday Spending is now being done online, the jobs are changing. Now more of the jobs, instead of being in the front room, are moving into shipping and handling, into warehouses, and into the actual delivery of those products. Jeanette washburn, a mother of six, is working in the Amazon Warehouse for the first time. So its good to have a little extra cash . Absolutely. Maybe a little out of the ordinary for the household. Do you want to do this full time . You know, if that was offered to me, i would consider it, definitely, but ill be back next season for sure. Last year, more than 20,000 of amazon Seasonal Workers were offered fulltime positions after the holiday rush was over. President obama continued a thanksgiving tradition today.

Allen, the spiritual leader of the worlds 1. 2 billion catholics is now in an area where there has been brutal fighting between christians and muslims. What is he hoping to accomplish . Reporter jim, i think the first thing he wants to do is bring the message of peace and reconciliation. He has said that christians and muslims can all sit down together, they should sit down together. Violence is wrong. Hell also talk about the environment, but that all comes back to his message that deprivation leads to terrorism. If youve got people who are deprived, theyve got reasons to fight, theyve got reasons for ethnic differences, thats a worry, jim. Early next week his itinerary takes him to the Central African republic, which is a war zone. Does he seem concerned about his own safety . Reporter as usual, the answer to that is no. Hes using open popemobiles and vatican officials, when you ask if hes wearing body armor, laugh as if thats preposterous. On the plane today, i asked if he was worried about the trip, and he said, to tell you the truth, the only thing im worried about is mosquitoes. When i said, me, too, he went like this and said, did you bring your spray, and smiled. And he didnt have to bring his, because one of the journalists gave him two cans, jim.

A turkey meal with all of the fixings is an ageold tradition, along with Football Games and thanksgiving parades. The biggest parade wil march down new york city this morning. Floats and balloons, upwards of a million spectators. Security will be tight on the route. Some Undercover Police you would never notice and others you cant miss. Michelle miller reports. Reporter on its busiest days, nearly 500,000 people walk through the streets of times square. So if anything should happen, the nypd says mounted officers like this will be on the front line of defense. Less than two weeks after the paris attacks, new york city and with up to 3 Million People expected to gather for thursdays thanksgiving day parade, officials arent taking any chances. We estimate we might have record breaking crowds because of the weather situation and were prepared for that. Were encouraging people to come on down. Reporter while many security measures go unnoticed, officers on horseback almost never do. But these men and women also known as tenfoot cops, do much more than act as a photoop for tourists. Sergeant, what do you see . Lots of people. This facility is a start of the art system. Reporter Deputy Inspector barry geldman is the commanding officer. How important are these horses to the force . Having that capability at a moments notice where you dont have resources there, but you can start to evacuate people or give direction is invaluable. Reporter geldman says the mobility of a horse gives police an added advantage when dealing with an emergency thats what happened in 2010 when members of the mounted unit evacuated times square just minutes after a bomb was discovered in a parked vehicle. People were taking direction from the mounted officers to move themselves from the location and it was clear communication. Reporter last week, they unveiled a 30 million elite facility to house the squad. Just a quit trot away from times square, penn station, and central park. The new location gives officers easy access to the citys busiest sites. A lot of people have never seen a horse before. They want to pet them, know his name. Sounds like theyre good at community policing. One of the greatest tools we have. Reporter new york city is one of the last cities to have horses on active duty. Talking to these two officers, they say their nonhuman partners are second to none. Despite the terrorist attacks in paris, mali and elsewhere, president obama says u. S. Intelligence has no credible evidence that any strikes are planned for the thanksgiving holiday. He addressed the nation from the white house. So as americans travel this weekend to be with their loved ones, i want them to know that our counterterrorism, intelligence, Homeland Security, and Law Enforcement professionals at every level are working overtime. They are continually monitoring threats at home and abroad. Continually evaluating our security posture. They did so before paris, and they do so now. Without fanfare or credit and without a break for the holidays. So the bottom line is this, i want the American People to know entering the holidays that the combined resources of our military, our intelligence, and our Homeland Security agencies are on the case. Theyre vigilant, relentless, and effective. In the event of a specific, credible threat, the public will be informed. We do think its useful for people, as theyre going about their business, to be vigilant. If you see something suspicious, say something. Thats always helpful. But otherwise, americans should go about their usual thanksgiving activities. Spending time w
