>> riot after gang members confess to the murder of 43 students kenneth bae and matthew todd miller are expected to arrive back in the u.s. tonight. kenneth bae was sentenced to seven years and forced to serve if a labour camp. mill rer was sentenced to -- miller was sentenced to 7 months. allen schauffler is standing by. what is the latest? >> we expect the men to arrive in the united states within the hour. they'll touch down at joint base louis mccard, an army and air force base outside of tacoma.

they'll be accompanied by james clapper. he is the one who went to north korea and brought these two men back. again, kenneth bae has been in captivity for two years, accused of spreading christian material in north korea, and accused of trying to hatch a plot to bring down the north korean government. matt miller was held for seven months. he went to north korea, tore up his visa and demanded asylum. he was accused of trying to be put in a prison camp in north korea so he can come back to the outside world and tell people of his experiences. miller and bay should be back in the u.s. within the hour, south of tacoma in a military base. the president expressed his relief.

. >> we are happy for their safe return and congratulations for a great job on a challenging mission. >> the president is on his way to asia for a tour and for the beijing summit. kenneth bae and his mother live north of seattle. and his sister who kept his plight alive in the eyes of the press, and a thorn in the side of the u.s. government, trying to get them to step up efforts to get kenneth bae free, posted a notice online thanking the u.s. government for its work, the north korean government and the swedish government. sweden is the one that has diplomatic footprint in north korea that we don't have, and does a lot of our work for us. she thanked all of those people, god, and said having kenneth bae back means it will be an extra special thanksgiving. >> i want to read that statement well. we mentioned u.n.

secretary-general ban ki-moon among leaders who were: do we know anything more about the men's health? >> you know, we don't really at this point, what their health is right now. as far as we know, matt miller has been in fair physical condition during his captivity. kenneth bae, according to his family, had problems. he was put into the hospital. he suffered diabetes, back problems, was seen by an envoy who said he lost about 50 pounds. he was subsequently taken out of the hospital and put on the labour farm where he was.

he clearly has had health issues. we don't know the state they are in now. we speght to learn more within the hour -- expect to learn more within the hour when those two men set foot on u.s. soil. >> it's been the ordeal. early, but do we know if kenneth bae or matthew todd miller will speak? >> we don't know at this point. we don't know if either will be up to facing the press or the government. we don't know what it means for north korea or the u.s. going forward. they are the last two american citizens held in the country, and it could signal that kim jong un is reaching out a little to president obama and the western world saying, "hey, here we are, we are ready to play ball a bit." >> a lot of questions remain. allan schauffler in seattle we talked about katharine

moon, senior fellow at the brookings institute and asked if this offered hope between kim jong un and washington. >> i think it offers hope. with north korea we have to watch for consistent substantive action. so what is interesting is that in the last six months, north korea has shown in europe, with japan, with south korea, and with the united states - first they released jeffrey fowl, and now the two gentlemen released today. i would say this is consistent in terms of the substantive positive actions. if they continue in this way, i think there is some hope for some creative and engagement between the u.s. and north korea. there are several ways to look at the value. what value does north korea have

or gain by keeping these people. i see the move as one getting rid of baggage that north korea doesn't know what do any more. he is frail, ill. if he was to get more frail or ill or god forbid die from your watch. the world would be eyeing north korea with more than a horrible look. and matthew miller is so young, to lock him up for six years, what's the point. >> moonsays the release of the prisoners could be viewed as an attempt by north korea. that could see his regime notened up in a criminal court for human right violations. more of that story during the night and day on al jazeera america president obama nominated loreta lynch to be the next attorney-general. lynch is a new york prosecutor who nose her way around

washington. >> president obama made the announcement of his new pick as attorney-general, with the outgoing ag. the president praised loreta lynch for her experience as a prosecutor and ability to deal with politics. >> loreta may be the only lawyer to battle mobsters, drug lords and terrorists and still have a reputation for being a charming people's person. that's because loreta doesn't look to make headlines, she looks to make a difference. she's not about splash, but substance. >> loreta lynch has been able to get through the senate, serving as the u.s. attorney for the eastern district of new york. encompassing new york city, manhattan. we are talking millions of people with high-profile cases. she received a law degree in harr forward in 1984. she's 55 years old. and from greens bro.

the president pointed out she's the daughter of a librarian. even though she comes from outside the president's inner circle, she has experience with eric holder. she chaired the ag provisor since last year. democrats are in charge in the senate judiciary. they start the process, the white house is not ramming it in before the new year. they may end up winning over into the republican led senate. mitch mcconnell weighed in on the pitch saying that ms lynch will receive fair consideration by the senate or in the new congress, through regular order. senator mitch mcconnell pushing the republicans to work on the process. >> loreta lynch, for her part, talked about the moment in time, what it worked for her to get

here, with the help and support of family and friends. she reflected on the significance of being part of the justice department. >> the department of justice is the only cabinet department named for an ideal. this is appropriate. because our worth is aspirational and grounded in gritty reality. >> this is a landmark nomination. if loreta limp is confirmed by the senate. she is the first african-american to serve as attorney-general. >> the president is headed to china to begin a 10 day trip across asia. the first stop is beijing. president obama says focussing on chinese-american relations will be a major priority during the final two years of his administration. after the apec meetings, the president heads to myanmar. heened with travel with his second trip to australia. >> more inspiration from apec. >> beijing has been preparing

for it for months. spending billions, and this is the result. pristine facilities, already to host the issua pacific forum. or apec. this is what beijing will not show the delegates. its gritty poorer neighbourhoods that the economic boom has left behind. judge and challenge shows us the two rooms he shares with his wife and family. he earns $250 clearing garbage, in a city that is home to more billionaires than any other mainland chinese city. >> translation: they lead different lies to us. living in nice places. i don't know how i can live like them. >> cobs for the urban poor have been yoesk. as a shortage of blue-collar

workers has been pushing up wages faster than for white collar jobs. it's in the countryside where the wealth gap is stark. with an estimated 100 million people living in poverty. with a potential for social rest, the government is aware of discontent that wealth inequality can cause, and is trying to help the poor in the countryside. >> such policies, like social security, policies - they are increased number of the rural household, more substantially. >> he moved here from the countryside when he could no longer support his family. they got running water and have enough to eat, and things for

his children could be better than he has had. >> we'll have more on the president's asian tour on sunday night. find out details of the plans over the last 24 hours, the fight against i.s.i.l. intensified. a wave of explosions killed 48 people and injured 100 others. reports detailed booby trapped homes and truck bombs targetting civilians and police. in syria, the battle is no better. at the edge of turkey, it's desolate. the city is caught in the middle of the coalition fight against i.s.i.l. this is what is left. a shell of what it once was. 200,000 fled. >> in an air strike attack forces reported hitting a gathering of i.s.i.l. leaders. the strike happened late last night. a convoy of 10 armed i.s.i.l.

trucks near mosul was targeted. they would not comment which leaders were there. 20 people were killed which car bombs in ramadi and baghdad. it was the same as previous bombings by i.s.i.l. five soldiers were killed. no one claimed responsibility former soviet leader gorbachev is not optimistic about the future. >> translation: the world is on the brink of a cold war. some are saying that it has already begun. >> gorbachev says the u.n. security council is not doing enough to mediate. germany is commemorating the fall of the wall with a spectacular display. 8,000 ball aborigines stretch across the area where the berlin wall stood. the route is 9 miles. this dramatic it delay serves as

a reminder of a history of a divided city. >> in a few minutes, we'll look at the fall of the berlin wall, and discuss the impact of the historic event 25 years later protests in mexico after the government announced new revelations in the case of 43 missing students. the mexican government said three suspect confessed to killing them. the family will not accept the news without proof. adam raney is in mexico city with more. >> protests in mexico turned violent as student and angry protesters torched vehicles and state government houses in that poor western state where the students went missing. meanwhile, in the capital in mexico city, protests converged on the plaza, where we had hundreds, if not thousands of people protesting against the government, calling for the resignation of the attorney-general, and the

president. this cams a day after the -- comes a day after the attorney-general announced that pictured criminals in the case had confessed to killing the missing students. he played grisly images of the evidence, and also re-enactments of these people confessing how they killed the students. after playing this provocative material and saying this before a national audience, the attorney-general said he considers the students missing. whereas the family members need this strategy by the government give updates on the case as a way of saying the students are dead, and not look for them alive, which is the main priority for the parents of 43 missing students, and they want the government to put in as much energy into finding them alive as in dead nissan announces a recall after reports of airbags shooting scrabs of metal into --

scraps of metal into the passenger compartment. next, which vehicles a man faces gaol in fort lauderdale for feeding homeless. just part of a new ordnance restricting feeding the homeless.

welcome back. tomorrow marks 25 years since the fall of the berlin wall. tonight we take a deeper look at how events unfolded and what it means for us today. >> first, here is courtney keeley with the bagged on why the wall was built. >> at the end of world war ii. germany was occupied by the western powers. russia's sector became independent. the american, british and french sectors became west germany. after the country was divided it was all-but impossible for germans in the east to seek freedom in the west. there was a loophole.

berlin was divided. in agreements among the four powers promised freedom of movements among the four sectors. capitalist west berlin was stuck like a bone in the soviet throat. by the summer of 1961 us thousands fled to the west. embarrassing the russians, that the east german government was given a mission to close the border for good. >> the flow trying to reach freedom is 1500 a day. >> the next day the east german army and police force built a barbed wire and concrete barrier. east berliners were told to stay home. >> the east called it the antifascist protected bull work. the rest of the world called it the berlin wall. what were initially coils of

barbed wire grew to a 100 mile double white concrete wall na snaked around west berlin, cutting off streaks. on the east german side was a death strip. soft sand to show foot prints, floodlights, trip wire machine guns, patrolling soldiers with orders to shoot on eight. >> eight were reportedly killed, trying to flee over the wall. more than 5,000 east germans, including 600 border garth managed to across the boarder. climbing over the barbed wire. crawling through the sewers, and climbing through unfortified parts of the wall. some of the daring attempts included one east berliner. jrman soldiers responded by tearing up the tracks. another used card is smashed into the wall.

one man drove his car without a windshield, defecting to the rest. >> in the world of freedom. the proudest boast is the leader. >> western leaders offered words of support, but remained unable to affect change. >> mikhail gorbachev open this gait. [ cheering and applause ] >> mr mikhail gorbachev tear down this wall. >> while it's believed that western ideology prevailed, economics played a key role in its demise. increasing numbers of east germans fleeing to the west in the summer of 1989, soviet leader mikhail gorbachev told the country's leaders they were on their own. >> on the afternoon of

november 8th, the east german government announced and told reporters that east germans would be able to travel to the west - immediately. 11.30 that night an east german surrounded by a crowd made the unilateral history-changing decision to open the crossing. >> as courtney mentioned the berlin wall was built in 1961. february 6th, 1989, mashed the last time a person was shot and killed trying to escape the berlin wall. east germans flocked after the wall was opened in an effort to move west. creating a political crisis in east germany. on october 18th the country's

leader was forced to resign. as a million people rallied, five days later, the government listed travel restrictions to the west. within hours demonstrators celebrated. >> on september 3rd, u.s. president officially announced an end to the cold war, and the following year on october 3rd, east and west germany reunited. something barely conceivable when the process began. to talk about the fall of the u.n. wall, we'll bring in director of the institute at columbia university. and from the university of texas our next guest. >> did that moment mark the end of the cold war? >> when the berlin war came down, it was a symbolic moment.

it was clear that fundamental caning was on the way. it's important to bear in mind that the combination of the change beginning in the 1980s, and the demonstrations throughout eastern europe were those that could drive the fall of the wall. >> i think it represented the cold war that anyone said in three significant ways. people came to recognise that those that had been the feared enemies were no longer the enemies. this was a mutual perception that changed. the economics of the relationship changed as well. as well as the west began to trade with the east and provide loans. the third most significant shift was the movement away from the fear of nuclear conflict. americans lived and soviet citizens lived with the fear of the nuclear war. that went away by the end of the

1980s. >> did anyone know what to expect when the gaits swung open. >> no, i was a first semester graduate student. i was in the midst of many. the level of un certainty was enormous. as we look out over the last 15-20 years, people's predictions about what we expected to see was largely unfulfilled. you could have made a lot of money by betting people in 15 years, seven countries of eastern europe. they were members of n.a.t.o. and joined the e.u., and the levels of violence was as low as it was. we can't diminish the war in yugoslavia, and ukraine, but then predicted ethnic violence in the region, and clashes between countries, we haven't seen that. >> the demonstration was remarkably peace:

a peaceful shot. any push back by the history could have changed. how much credit does mikhail gorbachev get for that. >> we have to give enormous credit. mikhail gorbachev contributed to these broader changes by calling for and opening up the system that he inherited in 1985 when he became a leader of the soviet union, and pursued a common european home. the idea of europe becoming whole again. they'll help overcome the subdivision. then, third, bosch made it clear to most people that he did not want to use force, and opposed the use of force. it is difference to the policy in czech or in pollen in 1980/81. everything would have been different if koch was not on the scene. >> i agree. we have to take into account

economic situation was dire. soviet union had become dependent on oil to finance the budget and oil prices came down. what makes mikhail gorbachev a remarkable individual, he was not the first to recognise there were deep political problems in the soviet system. the problem was in order to conduct economic liberalization one needed to conduct reform. he was able to push the reform further. he was brave enough to risk - he was brave enough to risk, introducing the political changes. and turned out the system was frail and brittle. >> when we dissect history, some would get credit for the u.s. government as the author for the

fall of the hall. >> i think that's an exaggeration. i don't thing we could ex-closed the united states. the way i put it is mikhail gorbachev was the key actor was important moves. many of reagan's closest advisors including the then director opposed any effort to reach out to mikhail gorbachev. we were skeptical of what mikhail gorbachev was doing as late as november 1997. what regan committed himself to was building a relationship with mikhail gorbachev, particularly after 1986, and the famous meeting. and regan was convinced he could work with mikhail gorbachev, and he convinced the american people of that. regan was not the actor, but he played an important role, as did western intellectuals.

western leaders. margaret thatcher and a host of leaders that are a part of the story. they stand below mikhail gorbachev in the importance of them as actors. >> if i can take up on this. i think the west was important in the model that it serves. for people in eastern europe, they saw what they wanted their countries to be like. apart from the personal relationships that president regan built, the model that gave the people in eastern europe and the former soviet something to shoot for was an important motivating factor. >> do you think it transported societies. >> the countries of eastern europe and the soviet union were modern, industrialized urban economy were well educated populous. the political and economic system were a bad fit for such a society. they could look across the border and see people that

looked like them, dressed like them, that they wanted to be like. people talked at the time. they spent a lot of time in the soviet union, and people would say i want to live in a normal country. they recognised that their country was an aberration from the other modernized society, and look across the border and say that's what i want. >> 25 years later, there's cultural differences between east and west. what have we learnt? >> well, i think the differences are significant. one thing we learnt, that is humbling for all of us as scholars and policy makers and citizens, is how difficult it is to change cultures. it is not destiny, it has a long afterlife. and certain memories, assumptions, pre judgments last and are deeply held. russians, for all of their desire to be part of the west, there is a suspicion still, and

that is felt in reverse. what we are seeing in the ukraine are some of the vestiges of that. within germany it's taken 25 years, really, for east and west to see themselves as part of one country. for a decade after. >> why do you think the right wing politicians prospered in the east? >> i think right wing poll fairness prospered in the east because on the one hand easterners were not living as well as western cousins and brothers, even after unification, and many of them distrusted their new fellow citizens and the largest european union that they were bombing a part of. right wing politicians play an fear and distrust. it's no different in east germany or anywhere else. >> i agree with germany. i want to stress if you look at the countries of eastern europe, they look like countries of europe, latin america, who were

at their stage of economic development. these are normal middle income countries with the problems of middle income countries. transformation is not pretty. there has been a lot of corruption. if you look, living standards increased, life expect si increased across the region and in russia, if you look at living space, people are living in bigger houses than they have. if you compare poland and the baltics to spain, greece or italy. the differences are less than we would have expected, given the level of socialism. >> do you think capitalism came too fast? >> the data is convincing that the countries conducting economic reforms from those that saw the shortest drops in g.d.p. and have done the best in engendering a market economy. it's those countries that were unwilling to introduce economic

reforms, chosen graduate paths with the cast of economic transitions have been higher. the evidence is clear on that. >> farmer -- former soviet president mikhail gorbachev says the world is on the brink of another cold war. >> i think that is dangerous. mikhail gorbachev is feeling remorse for a variety of reasons. i don't think we should take it too seriously. the cold war was a global struggle between two systems. he has not ha global struggle between two systems. we have a lot of regional issues and conflicts. ukraine won. the islands off china. they are filled with conflict. these are not global conflict between two systems that are devoted to the subjugation of the other one. we should be happy we are not living in the cold car. i agree with all the respect i

have. this is an overstatement. one way to put it is when i was in school i remember doing duck and cover drills to prepare us for the inevitable nuclear war that many expected to occur in the future. we don't have a sense of that. it is a serious problem. relations are bad. we agree on that. the crisis in ukraine is not the cuban missile crisis. >> we need to have prospectus here. >> thank you both and have you with us. >> coming up on al jazeera america feeding the homeless. cities are passing ordnances making serving public meals illegal. both sides of this debate ahead. and the nurse who defied a request for voluntary ebola is

making another announcement.

welcome back. nissan is recalling 52,000 vehicles because of possible air bag problems. it's part of a problem with bags from the japanese manufacturer takata corporation. 8 million recalls have been prompted. too much force is causing the bags to explode, causing chards of metals to go towards the passenger andrew fryberg passed away. the last wounded student hospitalized. the shooter gaol len fryberg was the cows gin. he took his own life after opening fire in the school cafeteria. the american nurse that fought back against an order in main is moving. kasi hickox spent the last two weeks and fort kent. she and her boyfriend are looking to relocate outside of

the state. monday marks the last day of the 2 is day incubation period. >> this week a federal judge approved detroit's plan to climb out of bankruptcy. it left the city, cutting 7 billion in debt. ali velshi explains what it will mean. >> a federal judge approved the bankrupt claim 6 months after the city became the largest bankruptcy in u.s. history. the go ahead came after a 2-month trial that cost the city $150 million in fees. by all accounts it was a speedy resolution for what was an incredibly complicated contest and financial deal making. when detroit filed for bankruptcy, it racked up $7 billion debt. 7 billion will be wiped out. some creditors settled for less

than what they were owed or taking cash, long-term leases. a key piece fell in place when bond insurers. retired city workers agreed to a 4.5% cut to monthly pension checks and a reduction in the health care benefits. these were the tough ones to get to. and in what is called the grand bargain, along with foundations and private fillan thronists kicked in there 16 million to avoid the sale of art. looking forward, the bankruptcy plan calls for $275 million in new bowing and another 1.7 million to remove buildings and sure up services.

the city's long-term viability depends on boosting tax revenue. growth, jobs and a need for people to move back and reinvest in detroit. it's a city that the with the big three automakers was a symbol of might. but it has become representative of how far america has fallen. in the near future, detroit will not be on its own. a new financial oversight board monitors the finances, and detroit's pension fund investment will be under supervise. >> "real money"'s ali velshi an elderly fort lauderdale man is facing charges for feeding the homeless in public. cities are passing ordinances restricting where meals can be served. officials say it's helping the

homeless. >> arnold abbott is 90 years old. supporters cheer him on after a run in about the law, after serving meals with the homeless on fort lauderdale beach. police served him with a citation requiring him to appear in court. >> they were gentle. i think they felt guilty doing their jobs. >> arnold began to feed the homeless two decades ago and formed his own nonprofit. feeding locations must be 500 feet from each other and residential areas. fort lauderdale joined a list of cities passing or introducing similar ordinances. many argue the laws are necessary to make sure public land is being used properly and address concerns over food safety. moving the mayors from the streets to shelters will help the homeless. >> we are not a city that lacks

compassion or kindness, we feel if someone is homeless on the streets, we need to get them off the streets into the right places where they can improve their situation. >> a pastor at the church points out shelters don't offer easy access to fort lauderdale's 10,000 homeless people. >> you have people that can't make it anywhere else. >> arnold plans on defying the law. arnold and the two ministers face up to 60 days in gaol, and a $500 fine. arnold has been through this before. in 1999 the city tried to stop him from public feedings. he sued and won. he plans to take the city back to court earlier richelle carey spoke to the director for the national coalition for the homeless and asked about the changing

policies towards homeless across the country and if activists would change their approach when it comes to helping the homeless. >> a compromise would be if the city of fort lauderdale, or any city in the downtown areas would make sure there were indoor food sharing programs available three times a day, seven days a week. that would reduce the number of people forced to wait for good samar tans to come by, hoping and praying that some group will show up on a weekend or a weekday. so - an indoor food theiring programme would reduce how many are waiting in the parks. there'll be people for whatever reason who can't make it to meal programs. we have a moral obliges to share food for those individuals. >> vet ners catalonia are set -- voters in catalonia are set to vote to breakaway from spain.

and rebecca with the forecast. >> it starts cold, but we get hit hard starting monday. we'll show you who has the coldest temperatures and who set a low pressure record. that is coming up.

live, as if they are in the separate nation. [ singing ] >> reporter: imagine a future in which catalonia becomes a nation. children from a town near barcelona can. >> translation: we want catalonia to be a free country, and we want the right to vote for independence. >> the dream is shared by many. on sunday, catalans take part in a public consultation on independence, after the spanish government blocked a referendum on the same day, calling it illegal. despite madrid's resistance. some have long flown independence. in 2012, jordie was the first mayor to declare his town free catalan territory. since then. $600 stopped paying taxes to

madrid. what the spanish government does not understand is that the more he stopped kat lanes deciding his future, the more he'll react and go to war. while the public consultation is not recognised by the spanish government. for many. given the number of catalan flags hanging from windows and balconies, it's clear that many support independence. catalans claimed that because of their history, culture, customs and traditions they are a separate nation from spain. despite attempts by the government to stop them, they insist that the time for independence is now. >> newly discovered human remains for flight 17 arrived in netherlands. it was taken to the army base

why 845,000 ceramic poppies cover the tower. next time you eat fast food, you may eat a genetically modified french fry. why it's better than a plain old potato.

pass 100 years after the start of the first world war the poppy symbolized a huge loss of life. peter sharp reports from london. in flanders field the poppies blow beneath the crosses row on row. the opening lines of a poem written by a young canadian officer that in one line of verse linked the poppy to the great war. and 100 years lair, the blood-red flower is the symbol of a nation's determination never to forget. at the tower of london, a river of poppies encircles the palace. each remembering an individual soldier who died in the first

world war. and there are 888,246 poppies in this dramatic installation entitled blood-swept lands in season. for many of the 3 billion visitors, emotionally charged. >> it's a concept for a tribute that i thing is necessary. i'm struck by how many people are here. it's wonderful. >> it's very emotional memory. >> seeing this poppy sparkling in the sun this morning. it's almost wrong that they sparkle like that when they are there. >> most here lost someone in the wall, it's a great tribute to them. along the railings families created galleries, pictures of the man who never made it back, connecting their loss with today's tributes. there are those that believe over the years the meaning of the poppy is subversive.
