discuss the effort to end the syrian civil war. >> numberem burg trials as the numberem burg failed to present the promise of presenting genocide. can facial recognition help police stop attackers before they can strike? >> good evening. tonight, we begin in turkey where a decision to shoot down a russian fighter jet is likely to have a lasting effect. the turkish government says the plane entered its airspace at two separate locations along the syrian border. turkey says the order to shoot came after the russian crew came after warnings. >> one pilot was killed and a russian marine. the russian military says he was on board a helicopter attacked by syrian rebels on the ground. the kremlin is disputing turkey's claim that the jet violated its airspace. russia insists the aircraft was above syrian territory when it came under fire. rory challands has that story. >> reporter: it was the angry language of betrayal putin described it as a stab in the back. >> we regarded turkey not only as a close neighbor but as a friendly state. i don't know who wanted what was done today. we didn't in any case. instead of contacting us, they addressed their partners as if it was us who downed their plane, not vites verse a. russia's defense ministry said it was not true that it was in turkish airspace or that it was warned by turkish jets. >> there were no attempts on the part of the turkishjets to communicate by mea. the rocket hit the planes. the place the plane fell was on syrian territory. the pilots were able to reject. according to preliminary data, one of the pilots was killed in the air by fire from ground. >> russia's first response was diplomatic. lavrov cancelled his trip to turkey. the second was commercial, advising russians it was unsafe for them to travel to turkey. and a military response of sorts, too. a russian warship is being sent to the coastline and cooperation with turkey's armed forces has been stopped. but worries of a serious e escalation of hostilities are being downplayed? >> we do not think this will lead to military confrontation between russia and turkey for the simple reason as turkey being a member state of the nato alliance, and russia wouldn't be interested in that. turkey wouldn't go in war with russia over this, of course. but what was the most likely intention of turkey in doing so was to assert boundaries. >> reporter: russia may look for more ways to retaliate, ratcheting up the air campaign. it had been going fairly smoothly. no longer. it's just suffered its first come at about fatalities, lost an expensive war plane and a helicopter. for that to have happened solely at the hands of isil or other rebels would probably have been considered an acceptable cost of war. but it didn't. it was inflicted by a country that russia says it treated as a friend. rory challands, al jazeera, moscow. >> nat 0 is standing behind turkey in this dispute after the jet was shot down, nato convened an emergency meeting. afterwards secretary general called for calm and urged russia and turkey to work to deescalate the situation. he also said alleys provided informati information. >> russia has questioned why turkey was so quick to turn to nato for help. president putin says it was as if a turkish plane had been shot down and warned it would lead to sequences for turkey. al jazeera's omar alsalah explains what that could mean. >> turkey and russia have had conflict for more than 400 years ago, to the first world war. in modern times, relations were quite as solid and based upon mutual interests and respect. the two countries trades tens of billions of dollars every year. >> 50% of turkey's gas is applied by russia. the war in syria has soured their relationships. the major reason for the increasing between ankara and moscow, russia backs assad whereas turkey is doing everything possible to bring him down. >> the incidents and previous tensions on the boarders and issues of violating turkish airspace and so on and so forth is a stol of a greater problem. the message turkey is sending by downing this fighter jet is not only for moss co. also to washington and paris. it said something very simple. you can't maneuver politically or militarily in syria and ig norris at the same time. >> tensions, russia airstrikes against isil and syrian opposition. last month, government leaders in ankara complained two russian jets violated turkish airspace. russia's targets inside syria also triggered a harsh response from turkey. on monday, turkish leaders called for the united nations security council to hold a meeting against turkmen. many have left their homes. the shooting down of the jet is going to reshape regional and international politics especially towards syria. french president francois hollande met with president obama. the two vowed to emerge victorious. as al jazeera's senior washington correspondent mike vaquiera says it makes coordination even more complicated. >> with con complicate looming between russia and turkey, a nato ally president obama wants to stoppents from getting out of hand. >> i want to ensure this does not esc lane. >> french president hollande agrees. as he set down with president obama in the latest of his meetings with world powers, he asked for allied unity against isil in the wake of the paris attacks. today, we wanted on the occasion of that meeting first of all to share relentless determination to fight terrorism anywhere and anywhere. >> as the air campaign is stepped up against isil, like mr. obama, hollande said french combat forces will not got into syria. both say there is no ultimate military solution there. instead, they stress the diplomatic push underway in vienna. unless russia focus on isil. the u.s. and it's alleys. russ russia's outlier, we hope they re-focus their attention on what is the most substantial threat and that they serve as a constructive partner. >> for president obama, his meeting with hollande was meant to send a message of unity not just with france but within the united states where rancor and whether they should gain entry into the united states has become a major issue. last week, at the g20, mr. obama scold would those who said refugees should be barred from coming to the u.s. >> that's not american. it's not who we are. >> his tone was criticized from both sides of the political divide. mr. obama said he understood why some are hesitant on the question of refugees but didn't break away from his vow to allow them access to the u.s. >> even as we are vigilant, we cannot and will not succumb to fear nor can we allow fear to divide us antonio, a continuing issue among european current can trees that need to share intelligence. president obama publicly pushing spoken nations to share airline passenger information, something that evidently isn't done right now. antonio? >> mike vac array at the whitehouse. >> douglas ol i have a nt joined us from d.c. a senior fellow at new america and served as the director for iraq in the obama and bush administrations administrations. good evening, doug. >> in light of the russian plane shot down by the turks, most people watching weren't born the last time a nato ally shot down a russian plane. and now, some analysts are raising the specter of a third-world war. how abo how will putin respond? i can't imagine he will force a confrontation with nato. >> the good news is that all sides seem to agree no one wants any type of military escalation. i have no doubt that there will be some response from russia, but it will be diplomatic and economic, perhaps sanction nothing military is expected. >> what about the turks? is there any danger they would want to escalate if they are going to stay on an aggressive footage -- footing? because they are noon too happy. the russians are bombing some of the alleys fight to go overthrow assad in syria. >>. it's still none to clear what happened. is its plausible to believe the russians did incur into turkish airspace? it's plausible. is it plausible that they shot down the plane because it was bombing the turkemen nidz ndz syria? we are not sure what happened. it's hard to imagine the turks would significantly escalate. nato is standing by the turks because there is at least a plausible belief that the turks are the aggrieved party here if the turks take the offense to the russians, clearly, that would put them in a very different situation with nato. this map shows bombers left northern russia flying near norwegian and british airspace so close that british airplanes, fighter planes, were scrambled. they escorted the russians for a while. the russian planes then crossed into the mediterranean, through the strait of gibraltar. they shot into syria before they headed over to russia over iraq,roon and the cats mean see. it shows how russia has been careful. it flies close to nato territory but doesn't fly over it. why, then, would russia risk ignoring the warnings from turkey because it has done so repeatedly there? >> it is hard to know exactly what happened it could be that the russians did not fully understand where they were, that they had a navigational error. again, it could be that they see turkey as the weak link of nato. clearly if you violate brilt issue airspace, that's one thing that long-time special relationships between the united states and great britain, they may see correctly that the united states is not particularly happy withtie given the lack of enforcement with their border, allowing jihadists to move and, therefore, see turkey as a somewhat outlier inside nato and perhaps a vulnerable flank. >> to that point, the russians argue they have been looking in that area for isil supply lines between syria andey. the turks said they are turning a blind eye to smuggling goods and people? >> i don't think there is anyone who believes there is still apply line that comes through sfwoishing syria supporting at least some of the jihadists. of course, the difficulty is the turks will tell you that it's the moderate rebels that are being supported. the russians and others will say that it's go can to other groups as well. there is probably some truth in both of those stories. >> do you think as we just heard one analyst argue that the turks could be sending a message to both russia and the u.s. that they are players to be taken seriously? >> i think this is not really directed at the united states. more so at russia, but clearly, the turks have some interests here on the table that they believe are not being fullly accounted for, particularly their concerns about the kurds and their continuing belief that assad needs to go now, not later, but now. this is a -- they are making a statement, but i think it really is directed at russia. >> so what do you think this incident does to the negotiations over a political transition in syria? could francois hollandeses efforts heading to washington and talking to ram ron in paris and meet with putin in russia, could there be some sort of grand anti-isil alliance that might succeed despite these increased tensions? >>. >> there is hope. everyone is focused on getting rid of isil and russia in the shootdown -- or the downing of its airliner coming from egypt. there is some agreement. but as this entire day has shown tensions with regard to some of the groups on the ground and what should be done with them, be those kurds or the turkomen. other groups that don't fit inside this mainstream, you know, left/right. are you for assad, against assad? >> it is a complicated situation. do you go ol i have a nt, good to have you navigate us through it. >> belgium has issued an international warrant for a another suspect named mohammed abrini, seen at a gas station with the 8th attacker still at large. it is warped he is probably armed and dangerous. french prosecutos say

isil crimeaed responsibility for a suicide car bomb that killed people in the sanai region. it came a day after egypt's second round of parliamentary elections. the hotel was hosting judges supervising the vote. two of them were among the people killed. sanai was shaken last month when a russian airliner crashed killing all 224 passengers. isil has claimed responsibility for that bombing. isil has been very effective at exploiting social media for recruitment and pro pa began a. the brookings institution analyzed twitter data to find out how many isil supporters are out there and where they are tweeting from. researchers found between 46 and 90,000 twitter accounts belonged to isil supporters throughout the world. most of them did not say where they are, but of those who did, nearly 1,000 claim to be in syria and iraq. 866 isil supporters said they were in saudi arabia. 404 said they were tweeting from the u.s. of the accounts that had their gps data enabled, it showed most were in iraq, syria and saudi arabia. none were in the u.s. however, only one and a half percent of the accounts had gps data enabled. two men accused of bombing a buddhist sideline were

found. soon after, riley was arrested as he was trying to cross the thai border. he confessed to being the bomb maker. despite the fact that police and army have said this attack was carried out by a network of foreigners and thais, only two people have been arrested. another 15 suspects are wanted but the fact that only two have been caught so far is perhaps further evidence of a case mismanaged from the start. the crime scene was cleared and the area around the sideline was re-opened to the public the day after the explosion. during the investigation, there were constants conflicting statements from police, military and the government. men are weigurs from china. thailand's military government says the attack was revenge for a crackdown on human trafficking. but there are many other theories, including domestic politics being to blame for the explosion. despite suspects being charged, unanswer did questions remain about the attack and why it happened. wayne hay, al jazeera, bangkok. >> secretary of state, john kerries said the recent wave of attacks must be condemned as terrorism after holding meetings with israel and the palestinian authority. he said the u.s. remains committed to achieving a two-state solution. the u.s. also recognizes israel's right to self defense. >> i express my complete complete condemnation for any act of terror that takes innocent lives and

hitle and his loyal deputies. six months after the end of world war ii, the city lay in ruins. the stadium that showcased the third reich's might went empty. with hitler committing suicide just before the war ended, the furor's inner circle was left to the answer for unspeakable crimes. on november 20th, 1945, in what was called the greatest trial in history, 24 top members of the nazi party entered the courtroom in nuremburg, gsoering, and founder of the gestapo. waiting for him, a military tribunal to be presided by the united states, great britain, france and russia. >> at nurembourg, the hitler gang has gone on trial. >> robert jackson, knowing the world would be watching let little doubt about the trial's significance. >> the wrongs which we seek to condemn and punish have been so calculated, so malignant and so devastating that civilization cannot tolerate their being ignored. >> the international tribunal, including sentences of death should they be found guilty of charges including the waging of aggressive war crimes against hu humanity later called genocide for ethnic cleansing. jackson and his colleagues were tasked with ensuring the trial would be fair and not used as a vehicle for ven answer but justice be served over nazi attacks. those in the so-called prisoner's doc claim it was a sham, when the accused were not allowed to use allied bombings as a defense. >> goering's defense was an attack, what the occupying powers are doing in germany now, he said was worse than the mild deeds of germany and rope. >> the trial lasted almost a year. no time, prosecutors showed a paper trail that led back to the accused. most of among the evidence collected by the allics, documents showing goeri in. g authorized the final solution over the jewish question. in the accompanying picture, prosecutors played films showing a nazi concentration camps and the atrocteas committed there. the slave labor and extermination of millions of juice. >> concentration camps was one of the things you found immediately necessary upon coming to power, is it not? >> yeah. >> now, all of the defendants know their fate. goering, to be hanged. hess, life imprisonment. >> all but 3 of the accused n i nazis were found guilty. the trial would be followed by others through april 1949. the trials hoped to be a deterrent for world leaders to ever committee war crimes again. instead, it served as a model for the others that followed including wars in the former yugoslavia and rwanda. to look tu trials and the their relevance today, we are joined by jonathan bush, a lecturer at law at columbia university who focuses on the numberem bourg trials. great to have you with us. the trials set an important precedent because some were advocating for summary executions and vengeance against these war criminals, instead, due process was served. >> that's right. i think that the trials were important because they show -- they showed the germans restraint. we didn't do a versailles. solution, the one we wanted after world war i of ven answer. we said we will fine the worsts of the worst, punish them fairly and establish a record, a written record that will be available for later generations and germans then. >> many hoped that the trials would be a deterrent for war crimes in the future to stop genocide in the future. on that level, they've failed pretty spectacularly, you would have to say because you still is had stalin, years of stalin and the horrors of mao, cambodia. you can go on and on. >> the easy answer is we have criminal laws at home and we have krimdz. det-terrence is a complicated process. i don't know if it works. i don't know if it ever works. the same is said of the u.n. they came out of the same impulse in the summer of 1945. we will punish the previous ones and we will deter the future ones with a powerful security council and the criticism is there of both. >> it also has failed to be a dettefrnt for wars of aggression. >> absolutely. >> another thing they hopped to do? >> absolutely. >> is the failure mostly attributable or at least partially attributable to the fact that there have really been very few international criminal prosecutions for war crimes since? >> well, clearly, there was a process, you know. you might think of it as rip van winkel, the international criminal law went to sleep for a long time after the last of the world war 2 trials and woke up in the early 1990s with the end of the cold war and trotsky is on europe's doorstep. would more prosecutions have helped? i don't know. germany belatedly after the ikeman trial started being more serious and had lots of trials on its own under german law, did that send a message to people elsewhere to bad rulers and torturers elsewhere? no. shooufrl not. >> it can't help that the u.s. hasn't ratified the treaty creating the international criminal court no have other current trees, china, indonesia. if you don't have those big countries on board, how can there be a true successor to the nuremberg philosophy? >> that's right. the new courts, both temporary and permanent icc, international criminal court, aim for that but with big players not in and with their own record subject to criticism, the trials have taken wildly too long. they haven't yielded memorable judgments or strong personalities. they seem focused on africa. it may be another international institution that will be seen in hindsight to have not been a defendant success. >> most of the cases are focused on africa. there were the trials for yugoslavia which convicted major war criminals there but in general, there haven't been that many. documented the principalses could be applied if it comes to that against isil? >> absolutely. somewhere, there is a quote. i am going to detit wrong. i think it says raw is the tribute that hypocracy pays to virtue. something like that. forgive me but everybody condemns genocide that's crimes, mass atrocities have been stig m matized in principle. whether that's a harm house towards their some day being rarer, i don't know. clearly isil violated every rule in the book and ripped up the book. will there be trials? them be gone by this then. >> to the tribunal get established? >> and try buenalds require victory in war or can they be done by a lawfully process in the 90s. >> jonathan bush, good to have you with us.

key component of new screening techniques could involve biometric scans. >> the technology allows officials to spot specific faces in a crowd offer at border crosses al jazeera's lisa moran gives us a closer look at what exactly the technology is capable of the use of facial recognition, iris and fingerprint scanning is being studied for wide spread application including the vetting of refugees. technofirst reported on this technology last year, dr. shini samara tested it out. >> you have had a issue with your face being out there you were count okay people recognizing it, not a computer. >> what is facial recognition? >> the idea that a computer can find the face and try to determine who that face is by searching a database. >> so is there a basic kind of concept of how it matches one face to this other? >> mathematical algorithims. it starts with finding a face in a digital image and determining features of the face like your eyes. once it finds all of those features of the face, it builds a template instead of numbers that represents a number of qualities of the face including geometry, distances and color or i willume nation. it's the template that's created that's used to do the search. >> along with other forms of bio metric identification like iris scanning, facial recognition technology was widely used by the u.s. military in iraq and afghanist afghanistan. this technology is currently being used to verify the identities of syrian refugees. in safe zones, united states refugee workers are using provide files with by 0 metric information. right now, if that refugee is applying for asylum in the u.s., several federal agencies including the state department, department of homeland security, defendants department and f.b.i. will take the bio metrics and with by graphical information vet the refugees against known terror lists. it is being tested for airport security. last spring, at washington dulles international airport, dhs and customs ran a field test, collecting biometric data from real passengers. it lasted three months and was designed to test the screening system's ability to detect immigration violations. >> al jazeera's lisa moran reporting. up to the minute tear results. a new mobile app trying to give you just that, created by a former cia operative uses a team of security experts to provide users with realtime information about terror threats. the app is supposed to make people feel safer. there are fears it could cause paranoia instead. the former cia covert intelligence officer, great to have you with us. why did you decide to crate this? why did you think it was important? >> i think for my entire career, i started off as an army ranger and ended being in the cia and as an add visor to senior members of congress. i saw throughout that progress in my national execute career that people didn't have real good information and information which we really need as the public to make solid decisions. >> talking about information, your app has a lot of it. i spend most of my waking hours following the news, and i got the app today. i was navigating through it. one of the things you've got is a world map. it shows different places where there are -- where there is information about possible terrorism. the amount of information that people can find by navigating across the world is astonishing. >> it is, and this is paired down. so what we have done is set up a -- it is pared down. we are searching through over 100,000 sources of information and then we have highly trained former intelligence officers who are going through it. so everything that you see has been processed not only by technology but by tried and true intelligence officers to give people information they need. >> how much information is there on there that is not publiaccessible? >> all of it is publiaccessible. so, it's knowing where to find that information which is, i think, what terror view and what we do, which is beyond what anybody else has done. >> so you are finding things that just aren't getting out there and should be out there more publi? >> absolutely because what we have also learned is that we don't have to

situation different or maybe it's not. we can give people relations and analysis they can't get anywhere else. >> are you worried wputting so much out there could worry people needlessly? >> no. i think it's going to do the direct opposite. i think by people understanding what the threat is, seeing the threat, especially if we are dealing with trailer, the app does 3 things, terror, cyber and by logical threats. for terrorism in particular, i think people are going to really be able to see that a lot of the threats and a lot of the talk is sort of off base. >> as someone who is immersed and has been for a long time, what worries you the most? >> what really worries me the most, especially from a u.s.-cent trick perspective is the biological threat. i think the biological threat is something we really don't talk about in the united states because isis has sort of dominated the discussion. but we really, the disease and the spread of disease is something that i think people will find very interesting in following terror view. >> joshua katz, the founder of terror view the app thank you for joining us. >> thank you. >> volkswagon is being investigated for tax evasion. saying
