I have lived in the city for years, but hong kong still makes me fall in love with it time and again. And now, bbc world news america. Reporting from washington, im katty kay. Apple asked a judge to reverse course on in order to unlock a terror suspects phone, and the head of the fbi admits it is a very difficult issue. This is the hardest question i have seen in government, and it is going to require negotiation and conversation. Stuck between greece and macedonia. As more nations shut their borders, thousands of migrants are left in limbo. In a new pop Art Exhibition opens in philadelphia, but even decades later, some of these images are still controversial. Katty welcome. Apple has asked a judge to reverse an order of that the company an order that the company helped the fbi to unlock an iphone used by one of the San Bernardino shooters. The original ruling created a firestorm in which Law Enforcement maintains it only applies to this one phone. Apple argues that it requires greeting at back, which it refuses to do. Reporter the San Bernardino killings in california before christmas, and the worst terror attack on u. S. Soil since 9 11. In the shootout with police, a mobile phone was recovered, whose secrets the police are desperate to crack, to determine whether tosh fema leaked or syed farook have accomplices. The movement to do that alik leaked tashfin m or syed farook have accomplices. I love encryption, i love privacy. When i hear corporations say, we will take you to a world where people wont look at your stuff, i think that is great, but Law Enforcement, which i am a part of, really does save peoples lives, and we do that through search warrants of mobile devices. Reporter at the moment, when the phone is locked, you have 10 attempts to enter a password, and after that all data on the device is a race. Apple is being asked to write new software to disable that function, so the phone can be bombarded with every conceivable numerical password until one opens it. But last night, the head of as they can go. Apple has cooperated with the fbi fully in this case. They came to us and asked us for all information we have on this phone, and we gave everything that we had, but this case is not about one phone. This case is about the future. What is at stake here is, can the government compel apple to believeftware that we will make hundreds of millions of customers vulnerable around the world, including the u. S. . There may not be another case like this. Apple is reported to be working on a phone that is uncrackable. That may be a boon for privacy campaigners, less so for those whose job it is to investigate the activities of criminal and terrorists. This will be decided in the courts, not by a small band of protectors outside the fbi hq, so they are not an isolated minority. Polls suggest americans are split down the middle on allowing the fbi do whatever it needs to, and the profound believe that some things, like he did on your phone, or none of the government does business. Jon sopel, bbc news, washington. Story, ifore this spoke with a New York Times reporter who wrote todays article about apple trying to make it harder to hack in the phones. Lets start there, matt, what is apple trying to do to make it virtually impossible for Law Enforcement to get into your phone or my phone . With the fbi is doing here is actually exploit a diagnostic mode that is built into every iphone. What that does, lets say your phone dies, or the software gets corrupted, apple has the ability with a up without new version of the operating system. What the Justice Department says is, great, just write us a version of the operating system with none of the security functions and booted up with that, and it turns out you can do that technologically without the users password. From a fixing the phone standpoint, that makes perfect sense, but if you are thinkiig about the idea of apple making the government hack into its own phone, it becomes tricky, so apple is working on answering the question of, how can we keep the diagnostic functions on our phones so that if our phone software dies, we dont have to pay for a brandnew phone, but also make it so that apple cannot be forced to upload new software on your phone without their consent . Katty the ceo tim coates said this is all about the future. Is this really about the future ofe customers, future customers, particularly millennials, who like privacy . I think it is more about the economy, and china being the largest market for iphones. It is definitely about the future. Law enforcement evening knowledges that this is about the future. You saw the Police Commissioner in new york city come out and say, look, i have 175 phones i would like to do next after the fbi is dumb with theres, so its not like this really is a one off, it is a one off in the sense of what they are asking for is one phone, but i think there is a recognition among Law Enforcement that if they will do it again. That if they get this authority, they will do it again. Katty but as i understand it, phone companies are authorized, but Companies Like google and apple are exempt. Why . Late 1990s,the when Companies Like at t and verizon were moving to digital networks, the fbi became concerned that they would not be able to eavesdrop on phone calls with warrants, so congress, after much fighting, passed a law that says, if you are a phone company, you have to make your Data Available in real real,of listening in a plain, listening way to the Justice Department, and that has been the law of the land. Google and apple are different. They are not phone companies, but they are also communication companies. This was just not envisioned by the law 20 years ago. And you said that director connie said this is the hardest decision he has seen in government. Lets keep in mind that jim was involved in the decisions about wiretapping and waterboarding. This tells you how deeply divisive this issue is in the United States. Katty and around the world. Thank you for joining us. Greece has recalled its ambassador to austria amid tension of how eu Member States are handling the migrant crisis. Officials in athens are angry that they were excluded from the meeting on how to address the problem. Austria and a number of balkan states have proposed their own border restrictions, which have left thousands of migrants stuck in greece. Danny savage reports from the greecemacedonia border. Reporter pouring off the ferries at athens after landing on the beaches of the greek islands, in the last three days alone, 8000 migrants come to greece. This unstoppable flow of humanity can be found throughout the country. , a miles north of athens group of several hundred walk the last few miles to the border with macedonia. Frustrated at having the way to cross. Having to wait to cross. We have stayed in the camp for three days, and they do not let us go to the border. Reporter thats when they get here, to the overcrowded border camp. They will be out of luck. Progress on the trail is at a virtual standstill. This is the one dates that migrants going from greece to macedonia have to pass through, but for much of the last few days, it has stayed shut. Authorities say that is because the next border going north, between macedonia and serbia, is closed as well. It is the classic domino effect. Borders further north close, so this one stayed shut too. Border, the train was stuck for hours, and frustrations grew. So a backlog of coaches and communities is building up down the line. This is a service station just short of the border. Greece is in danger of becoming a warehouse of souls, set a minister here today, and lots of them are little souls. There has been a sharp rise in the number of children on the move. These iraqi twins were born in turkey and have been traveling all their life. We have an concern for unaccompanied children, who at the moment, there is not sufficient baby care. Reporter now new cancer having to be open for them. The greek government is furious about decisions to restrict migrant flow. There is no agreement in brussels on what to do to tackle the situation. The intentions of some countries are obvious, though. The fear is that the migrant system is on the brink of total collapse. Danny savage, bbc news, greece. President obama traveled to the u. S. State department for a meeting with his National Security council, focused on the fight against the socalled Islamic State. It comes on the eve of a scheduled truce in syria, which does not include the ongoing battle against isis. I spoke about the situation with the former supreme allied commander of nato, now the dean of the Fletcher School at tufts university. Migrants from the middle east into europe is not going to stop until the situation in syria is resolved. We have a ceasefire that is due to come into effect on friday. How much impact will it have . First of all, i am extremely peasant mystic that the ceasefire will actually take hold. Themany of the big players, u. S. , russia, the syrian opposition, etc. Are friendly not in position to make this happen, but lets say it does come into play, i do not think it will have any effect because people on the ground will not believe it. Katty and the facc that al nusra, france, and the socalled Islamic State are a part of this treaty, does that voided from the beginning . I think it does. The real hope on the ground is on imposed solution from the outside, much like in the balkans 20 years ago, but until the u. S. Aad russia can come to , probably over the length of time assad will be allowed to remain, i think it is unlikely we will get to a solution. Katty is it just assad that is a Sticking Point for the white house, or is it a broader issue that even if they could agree on assad, this white house is so reluctant to get more militarily involved, that even safe zones are nofly zones are nonstarters . About 80 ofsad is the challenge, but if we can get over him, the technical, military aspects of this, lets say, creating a safe zone in fighting troops to do that, that is an eminently accomplish double task. Able task. Ish katty where were these troops come from . I would like to say local nations. Jordan, turkey, iraq, nodding conceivable if we can tear down the Islamic State in iraq. The saudis have made noise about participating in this. It would have to be a u. S. Nato core of 5000 6000, but you could bolt on another thousand and create that kind of safe zone. Katty you describe a scenario that can work for safe zones, but the premise is agreement between the russians in the United States on the future of assad. ,o you think that the russians having launched their airstrikes , that they are coming around the idea that maybe they do have to play ball when it comes to assad in syria . I think so, particularly when Oil Prices Continue to be so low. You are starting to see the bite of the sanctions in russia. I think we are at the point where there will be some level of give on the russian side. It will not be an on and on switch where suddenly the lights go on, hopefully it will be a little bit brighter. I think the thing that needs to be on the table at some point is a partition of syria. Katty which may happen. Let me ask you about libya. We had the director of National Intelligence speaking in congress today. He said he has great hope that there could be a government of National Unity in libya soon. It is a big concern when it comes to the spread of the Islamic State. With that make difference . It would make a huge difference. I agree with him. I think it is a possibility. You see a glimmer of hope. Ironically, the presence of the Islamic State is what is mobilizing that. Neither the groups in the east nor the groups in the west, particularly general half dollars forces in general , want to seeces the Islamic State dig in. If we, the west, can find partners on the ground in that regard, i think we have a shot at bringing libya back from the brink. Katty thank you so much for coming in.

On part of our continuing road top, regina went to arkansas meet lgbt americans that say discrimination is a major problem. They dont care about caitlyn jenner. They believe about what their interpretation of the bible is, and they unfortunately oftennuse that to justify kicking their child out of the home. I have been punished, i have been hated.

Reporter there has been a generational shift in attitudes toward lgbt writes, but in some parts of america, these views remain entrenched. Katty now, think of pop art and andy world halls pop art and andy warhols Marilyn Monroe might spring to mind. These artists were exploring notions of celebrity and sex to produce work that was bold and subversive. Pop art was also a global movement, as then exhibition at the Philadelphia Museum of art makes clear. Some of these images are still attracting controversy. Copart first onto the scene in the late 1950s and swept the globe. It was commercial, subversive, youthful, witty, and sexy. Fact, that this image of a woman licking Ice Cream Cone was censored by facebook just a couple of weeks the Philadelphia Museum of art used it to advertise this exhibition. I think it was surprising, but it was also a great reminder of how shocking this work can still be, and how relevant it is. Thatf the great debates happen on facebook and instagram and all of our Different Social Media feeds was why this image would be so troubling to some people, or not troubling to other people. Reporter sex, of course, still sells, but the pop art was when it first became commercialized, and a heady brew of consumerism and sensation. Confined towas not the u. S. Or britain, where it had its roots, this was an international movement. These artists were grappling with the new reality around them, and representing it in their work. Reporter these panels were created by brazilian artists in the 1960s when the country was experiencing a lot about people. They are a comment on censorship violence. Rtrayal of these images were censored in the newspaper. The artists, however, has given up the ability to uncover them. 87 artists are represented in this exhibition, and no many of and though many of these works are half a century old, they remain exuberant and provocative as the day they first popped onto the scene.
