And now, bbc world news america. Jane this is bbc world news america. Im jane obrien. Rains are carried out in germany, searching for the suspect in the berlin market attack. Authorities say there is clear evidence linking on a separate amri to theanis deadly assault. Donald trump and Vladimir Putin both talked about strengthening their Countries Nuclear capability. And perseverance is inspiring. One man who lost all his limbs to illness is now looking to extraordinary new life. Jane welcome to our viewers on Public Television in america and around the globe. There is clear evidence linking anis amri to an attack on a Christmas Market in berlin. That is the word from German Authorities today, who says his fingerprints were found on a truck that sped into the marketplace and kill people. His brother called on him to give himself up. Our europe correspondent has the latest. Reporter it is new footage that has just emerged. The scene immediately after mondays attack, filmed from a dashboardmounted camera. A few seconds earlier, this is what happened. We have slowed the footage. From the left comes the laureate speed, heading straight for the Christmas Market. Manthis is anis amri, the police say was driving it. Humming, video posted to his Facebook Page in december. Now the 24yearold tunisian is europes most wanted man. Police first found his id documents in the cab. Now tests have shown his fingerprints on the door and the bodywork. The conclusion, he was at the wheel. Angela merkel this afternoon thanked germans for their measured reaction to the attack. Chancellor merkel our thoughts are constantly with the victim relatives and the injured. We know it to them to give this our very best. I can say we have done a lot in recent years to meet the challenge of terrorism. Reporter police raids in germany earlier today contacted anis amris known contacts, turning up nothing. His family in tunisia last saw him five years ago. They say he was not religious, drank alcohol, and dreamed of owning a car and starting a business. If my brother is listening to me, i want to tell him to surrender for the sake of our family. We will be relieved. If he did what he is suspected done, there will be dishonor on us. I am sure he is innocent. Left his anis amri family illegally in 2011. He spent four years in jail for violence and theft. Without a passport, he could not be deported to tunisia. Last year, he went to germany. Denied asylum once again, he was not supported. Police said he was trying to get automatic weapons for an attack, but with no new evidence, surveillance was halted in september. Should authorities have taken the threat posed by amri more seriously . For most germans, as the markets reopen here with new security barriers, criticism of the police is less important than how they respond. Getting breitscheidplatz back up and running today was symbolic for berlin. We have to respond to the terrorists that we dont care, we are going to open. We are not scared. Its exactly what they want. Reporter crowds were thinner than usual. They wanted to show they would not be cowed. I have come to show we must not hide, says rosemary. Im very sad. I was here on monday. Luckily i left before it happened. I feel anger and sadness, more anger. I did not know any of the victims, but it makes me really angry. Not so much fear as defiance, then. Berlin is determined to show they will not give up the things they value and enjoy. In damascus, bbc news, berlin. Jane furthermore, i spoke a formerime ago with a u. S. Director of intelligence. Thank you for joining me. It does seem that an awful lot was known by an awful lot of people, both foreign governments and by different intelligence agencies. Could this information have been better shared, and would it have done anything to prevent this attack . Certainly it could have been better shared, and it might have done something to prevent the attack, but as long as we are only playing defense and trying to catch people after they commit an act of terror, or even just before because we have good data, we are going to lose. Its like trying to win a hockey game and having all your players play goalie. We have to get out on the offense. We have to go after the terrorist groups. We have to conduct surveillance of them extremely thoroughly. We have to be in those enclaves europe, ofl over islamist groups. We are not moving nearly definitively enough. Jane but doesnt that cause the type of conflict, particularly in germany, between privacy, which europeans treasure an enormous amount, and the need for protection. How do you reconcile those two . Guest i think one can protect privacy. There is a great deal of Data Available at companies such as sapient and others that have huge amounts of publicly available data, but that can be used very effectively to track people without interfering with their private lives or anything that is hit in hidden or in their home or whatever. Jane what about the issue of sharing this information . When you have different nations involved and the u. S. , how do you go about improving that, and does there need to be a rethink in the wake of the migrant crisis . Guest i think there has to be a major rethink, given how generous germany and other states have been at letting 1. 2 Million People in from the middle east, as germany has. And only about half of those were declared not available for asylum. The others, i think 30,000 of them are working, but that is all. Letting huge numbers of people from a country like syria into your society and not having jobs for them is a recipe for disaster. Jane but could the u. S. Do something more to sharthe intelligence it has . There are reports that amri was on the u. S. Nofly list. Good that sort of information be shared, and would that help . Guest i would be surprised if the nofly list was not communicated to european countries. There are two nofly lists. There is one that gets you stopped briefly, and another that makes you not able to fly on the plane. It is important to share that well. I think our sharing improved after 9 11, because one of the things that we did wrong was not even have the fbi effectively talking to the cia and vice versa. We were restricting, in privacys name, a great deal of intelligence sharing. We reported that out a bit we have worked that out a bit better now, and there have been improvements, but europe still shares very little. Jane thank you very much for joining me from new york. Guest good to be with you. Jane Nuclear Weapons were the topic of the day, both here and in the u. S. And in russia. First it was Vladimir Putin who spoke of the need to bolster his countrys nuclear arsenal, then it was donald trump who took to social media, saying america needed to strengthen and expand its nuclear capability. Bbcs defense correspondent Jonathan Beale reports. Reporter america and russia still hold more than 90 of the worlds nuclear stockpiles, both able to deliver destruction on a massive scale i grant fiore. For a quarter of a century, they have been reducing their nuclear arsenal, but the question now is the arms race about to resume . Tonight, president elect donald trump tweeted, the United States must greatly strengthen and expand its nuclear capability, until such time as the world comes to its senses regarding nukes. It caught many by surprise, including the obama administration. I cant speak for what the president elects nuclear views or his policy going forward, thats for him and his team to speak to. What i can speak to is the approach this administration has taken to get us on the path to a World WithoutNuclear Weapons. Reporter president putin too has been ramping up the nuclear rhetoric. Today, addressing his military commanders, he talked of the need to strengthen russias Strategic Nuclear forces. We can say with certainty that we are stronger now than any potential aggressor, anyone. Reporter both the United States and russia have made large cuts to their Nuclear Arsenals since the height of the cold war, but they still have many weapons. The u. S. Has stockpiles of 7000 warheads, of which 1900 are deployed or ready to use. Russia has just over 7000 warheads with just under 1800 deployable, while the u. K. Has 120 available to use and could be fired from vanguard submarines. Both america and russia are already modernizing their Nuclear Weapons systems at significant cost. What is not clear is whether donald trump wants to go much further. Tensions have been rising with russia. These u. S. Troops on exercise and the baltics, a response to its intervention in ukraine. Russias military campaign in syria has deepened the risk. But donald trump has signaled he wants to improve relations with moscow, so his comments might be more directed at north korea, whose unpredictable leader boasts of now being a nuclear power, or even iran. Donald trump certain to rip up a deal with its nuclear program, still suspicious of their intentions. Did withonald trump that tweet is start the nuclear arms race. It is not strengthen our nuclear arsenal, its expand our nuclear arsenal. We have arms control limits that cap the weapons we deploy. He pays no heed to that. He seems to want to bust through the caps. Reporter with Nuclear Weapons, words matter. Once again, a donald trump tweet has surprised and raised plenty of questions. Jonathan beale, bbc news. Jane for more on trumps comments today, i spoke to a brief time ago with the bbcs laura becker, who is at the white house. Laura, a tweet can mean many things. What has his Transition Team made of it, and they have been able to satisfactorily explain what he might have meant . Reporter the problem with tweaking policy in 140 characters or less is that it is difficult to paraphrase. The statement said president elect trump was referring to the threat of Nuclear Proliferation and the critical need to prevent it. They said he was talking about terrorist organizations and unstable regimes. But he does not name them in the statement, which means we are left to guess, who are these rogue regimes . When it comes to terrorist organizations in previous interviews in the runup to the election, donald trump did not roll out using weapons of mass destruction against a socalled islamic state, for instance. He said it was important to be unpredictable. But what does it mean when he finally takes power . When it comes to what he could actually do as president , there is already a trillion dollar package going through to revamp americas aging nuclear program. Therefore, adding to that would be rather costly. But only one man really knows what he meant to do, and that was donald trump himself, and he will get his hands on those Nuclear Codes in just 29 days time. Jane of course, this is not the first time he has tweeted about very sensitive subjects. You have been covering donald trump for a long time. Is this something we just have to get used to . Reporter i think its something weve got to get used to. There was a saturday night live sketch when Kellyanne Conway came down the stairs, labeled Kellyanne Conways day off, where she was brought in on her day off several times to explain Donald Trumps tweets. When it comes to twitter, donald trump loves his twitter account, and he seems to get a reaction from it, so he is likely to continue doing it. The problem with that brevity is it takes his Transition Team to explain it. Vicker,r laura thank you for joining me. Iraqi forces have launched car bomb attacks in the city of muscle.

There is nothing you could have done, nothing at all. In some respects, that is better. Ive got no blame. No one tried to blow me up in war or any sort of conflict. It was just a bit of bad luck. Reporter alexs bad luck started in 2013 when he went from this to this. After a cold became a strep a infection, which led the blood poisoning. For his partner lucy, seeing his mouth and nose disintegrate and his arms and legs amputated was devastating. I could not go in the room to see him after it. I found it difficult.
