They are in touch with their italian counterparts but we need to stress these are still unconfirmed reports. And just to give you a little logistics hallie, milan is about 11 hours south of berlin. That would be by car. That would give you a sense of just how long it took from him to travel here where we know he was on monday. Again this confrontation with police happening at 3 00 in the morning and amri allegedly unconfirmed, shot dead. Hallie . Hans, had there been any suspicion that anis amri had travelled to italy or is that a surprise to investigators, perhaps . Do we know . Well, its not necessarily a surprise. Because remember we he came here from tunisia, he originally landed at an island off sicily, off italy. He spent 3 1 2 years in italian prison in sicily. And that is where his brothers, at least according to reports out of tunisia, say he potentially was radicalized. He gets out of prison in italy, makes his which up through europe, traveling to switzerland, germany 2015 in july, applies for asylum. Has that rejected. Had been under surveillance by authorities in berlin. They didnt have enough to continue to go with surveillance. They eventually take their eyes off him in september of this year and four days ago you can see behind me the Christmas Market now returning to normal. But such a scene o carnage. Hans nichols coping us updated on this. I want to bring in nbc news Foreign Correspondent ayman mohyeldin. We know that the German Prosecutors Office is in touch with their italian counterparts. Talk about the cooperation now between these Police Agencies that needs to happen and the next steps moving forward. Theres no doubt about it. First of all theyre going to try and absolutely verify the identity of anis amri. Theyre going to check his dna, fingerprints, make sure all of that is, in fact, what the germans have at the scene of the crime there in berlin. Make sure all of that adds up. And more importantly theyre going to try to piece together the journey that he made from berlin to italy over the past several days since this incident happened. They want to try to make sure that there are no accomplices involved that help him escape. Keep in mind if he was traveling from berlin to italy throughout all of this ordeal did he buy a ticket . Did he take a train . Did he drive a car . Who drove that car . Whose car was it . Did he rent it . There are a lot of questions in the investigation that are going to push authorities to try and trace every step he took from the time that he actually carried out this attack in berlin to this incident now according to Italian News Agency where he was shot dead. Thats going to be one of the more important things in the coming hours. In addition to that its going to be to the leadup to the attack in berlin. Theyre going to go back and try to time everything out from the moment he arrived in italy to tunisia, as hans was reporting, what led him to ultimately carry this attack out. And again, the key question here is going to be did he act alone, was this an attack that was inspired or coordinated or directed by somebody else as weve seen in other attacks like brussels, as well as in paris. Thats going to be a central question for the investigators Going Forward. You raise an important point. The question is how will they end up getting to the bottom of whether or not he was alone. Who may have helped him, as you point out, in the journey from germany to italy. Can you talk about the investigative procedures here . What might Italian Police be doing . How german prosecutors and authorities might be working with them, as well . Theres a few different elements here. One, some of the intelligence that weve learned from italian investigators suggests that, in fact, anis amri had spent se time in italian jail. Now they dont believe he was necessarily radicalized. And this is according to the head of the Italian Police union. They dont believe that he was necessarily radicalized in italian jails. They described him as a criminal. As a troublemaker. Somebody that was ultimately put in solitaire confinement. But theyre going to start by looking at any associates that he may have had inside any of these jails, and other networks that he may have established. But one of the key pieces of evidence Going Forward is once theyve identified this individual, confirmed that he is who he is, theyre going to try to see if he had any links and that includes things like social media foot prints. Did he have any kind of communication, cell phone, tracing the cell phone records, seeing where it pinged in terms of his movement. See who bought the cell phone for him. Find out if he had any bank accounts. Where was he getting any money . Was he working . There are key pieces of evidence that theyre going to use to try to establish what they call pattern of life behavior. What was his pattern of life that led him to commit this crime . And this terrorist attack. And theyre also going to see if he had any overseas travel that may have or should have been flagged. We know that the United States had anis amri on their radar for his isis affiliation, or his isis leanings, if you will. So he certainly had something that had been flagged by both u. S. Officials, and perhaps other european counterparts. Why was this individual not in jail . Well thats going to be a central question perhaps down the road. Why was this an individual that they knew because weve also learned, hallie, that he was under surveillance by German Authorities who suspected him of potentially carrying out a terrorist attack. So theres going to be a lot of revision about some of the key decisions made by authorities but also trying to piece together every aspect of his life. Nbc news Foreign Correspondent ayman mohyeldin. One day after meeting with top military offices, president elect donald trump released a vague twitter post indicating a major shift in u. S. Security policy. Quote, the United States must greatly strengthen and expand its Nuclear Capability until such time as the world comes to its senses regarding nukes. His comments came on the same day russian president Vladimir Putin said russia needs to strengthen the Strategic Nuclear forces, praising their triad launch capabilities. Now the United States and russia possesses 95 of the worlds Nuclear Arsenal and in recent decades have agreed to shed epens which they have done to a dramatic extent since the 1980s. Now president obama recently introduced a longterm plan to modernize Americas Nuclear weapons Delivery Systems which critics say will cost a trillion dollars. But in july the president was exploring options to reduce the cost and limit Nuclear Weapon use. It is still unclear what is the exact meaning of trumps words. Transition spokesperson jason miller released a statement. President elect trump was referring to the threat of Nuclear Proliferation and the critical need to prevent it, particularly to and among terrorist organizations, and unstable and rogue regimes. He is also emphasized the need to improve and modernize our deterrent capability, as a vital way to pursue peace through strength. And Senior AdviserKellyanne Conway says that she spoke with the president elect directly about the matter. I dont think the tweet was groundbreaking in this regard. It seems that president obama himself has invested, has called for an upgrade in our capabilities. I read in one or two articles up to 1 trillion is the price tag. We all, president obama, president elect trump, everyone shares the same, i think, core value and their first duty is to try to keep us all safe. We kw its a dangerous world and that includes Nuclear Weapons. President obama, and president elect trump have talked privately a number of times over the last six weeks. But yesterday the incoming president sent a very public message to the white house about a United Nations vote critical of israel. Diplomatic Officials Say the Obama Administration had planned to abstain on a Security Council resolution calling for an end to israeli settlement building in palestinian territory. Basically a bitter end to another president s peace efforts. And a particularly fraught relationship with israeli Prime Minister benjamin netanyahu. Now after this resolution circulated on wednesday night, netanyahu publicly called for the u. S. To use its veto power as a Security Council permanent member. And a senior israeli official confirms the Israeli Government asked president elect trump to weigh in on the United Nations vote, essentially helping to, in effect, stop the resolution. In a statement, trump said, as the United States has long maintained peace between the israelis and the palestinians will only come through direct negotiations between the parties, and not through the imposition of terms by the United Nations, this puts israel in a very poor negotiating position and is extremely unfair to all israelis. What happened hours later . The scheduled vote was delayed by its egyptian sponsors who also reportedly faced pressure from the Israeli Government. Israel was also reportedly alarmed at secretary of state john kerry planned to deliver a speech on the Israeli Palestinian situation, which his spokesperson confirmed at a briefing. Listen. The secretary was preparing to to deliver some remarks today. About a vags for the middle east, and certainly the middle east Peace Process itself. And he decided that in light of the postponement of the vote that it would be prudent for him to postpone his remarks. In washington earlier this month, secretary kerry called the israeli settlements a barrier to peace. With president elect trump weighing in on the middle east Peace Process ahead of taking office some are questioning whether trump is hampering the Obama Administration during its final month in office. Something his Senior AdviserKellyanne Conway has denied. President elect trump is being incredibly respectful toward president obama and toward the fact that until january 20th we have a sitting president. At the same time hes asked his opinion on many different matters and in most instances, this is not the first time hes been asked or has provided his opinion. Hes done that all through the campaign. So it should really surprise very few people this is his position. At the same time hes not going to act on it until hes actually in the white house. And president elect donald trump announced the position of Kellyanne Conway to the white house staff while also unveiling his Communications Team with sean spicer as press secretary, Campaign Spokesperson jason miller taking the role of White House Communications director, and two of the original trump staffers, hope hicks, and dan scavino are getting west wing offices, the directors of Strategic Communications and social media. It seems the president elect will rely on social media for many of his statements. Last night trump tweeted quote the socalled a list celebrities are all wanting tickets to the inauguration. Look what they did for hillary, nothing. I want the people. This comes after reports of high profile entertainers turning down offers to take part in inaugural festivities. A report from politico that former president jimmy carter it the only excommander in chief currently planning to attend trumps swearingin. Others are waiting to decide. Yesterday it was announced that the mormon tabernacle choir will be performing for the new president , having last performed at george w. Bushs 2001 inauguration. Turning now to syria where after a devastating and deadly four years of fighting, the battle for aleppo has apparently ended. The syrian army announced its completely retaken the ruined city adding that they have quote, liberated it from terrorism and terrorists. Evacuations now ending with the last remaining rebel fighters and civilians who wanted to leave doing so. About 40,000 people just since last week. Despite all of this, though, the more than six year long civil war is not over. Rebel groups are holding other parts of the country, including as you see there the city of idlib which president assad has promised to retake. At least 23 people are dead after a car bomb exploded in mosul, iraq, yesterday. 15 civilians and 8 police men are confirmed to have died. It occurred in the area of the city which iraqi forces previously liberated from isis, and is the deadliest bombing in that area since that time. And a passenger on a on board a jetblue flight claims he was removed from the plane after an incident involving vancouver ka trump, Donald Trumps daughter. Vancouver ka, her husband Jared Kushner and her children were preparing to travel out of new yorks jfk airport when they were confronted by a fellow passenger. Ivanka and her family landed safely in San Francisco but two men were removed from the flight before takeoff. Before the incident one of the men removed from the plane tweeted that his husband was, quote, chasing them down to harass them. He got on and said oh, my god this is a nightmare. And he was shaking, and jetblue sort of approached him, and he said jetblue sort of approached him, and he said he said, you know, they ruined our country, and now theyre ruining our flight. He was upset. He walked on as soon as he saw her he started shaking. He was visibly shaking. He was agitated. Jetblue later released a statement saying in part the decision to remove a customer from a flight is not taken lightly. If the crew determines that a customer is causing a conflict on the aircraft, the customer will be asked to deplane.
