first lady. welcome to our vielers on publicision in america and around the globe. could it be time for north korea and the u.s. to talk? after months of tensions, kim jong-un has hinted he is willing to start discussions about dismantling his nuclear weapons, but only if his c's safety is guaranteed. today president trump claimed credit for the move, pointing th tough sanctions by the u.s. and u.n. the bbc's nick bryant starts oue cove nick: normally it is the from the a sab north korean leader, now a war shake of the hand. on state television, the schmaltzy soundtrack doubled as diplomatic mood music as kim jong-un greeted a delegation from south korea. he has apparently offered to abandon his country's nuclear arsenal in return for security guarantees from the united

states, the first times proposed that kind of deal, and also to suspend nuclear and missile tests while itngaged in talks. no w adversaries parted on such cordial terms. it is the most significant overture in a decade.e sponse from president trump in washington, caution and self-congratulation. d >> to whyou owe this recent openness to talks? y esident trump: me. no, i think -- nobt that. i think they are sincere, but i think they are sincere because thee sanctions and what we doing with respect to north korea, including the great help we have been gen from china, and they can do more, and i hope they are sincere, and we are going to soon find out. h korea's nuclear an missile tests have presented the trump administration with its gravest foreign policy

challenge, and he has responded with sanctions and tougher talk. president trump: they will bet th fire and fury like the world has never seen.et roan is on a suicide mission for himself and for his regime. nick: next month, we we more joint military exercises between the u.s. and south korea, drills which pyongyang has always regarded as a dress rehesal for more. washington has said that the military option would be on th s table until s credible, verifiable, and concrete steps towards north korea's denuclearization. there is a sense in washington that we've sn this movie before, that north korea has engaged in talks with previous niadrations while at the same time developing weapons that could threaten east coast cities like new york and shington. but there is also a sense of self-satisfaction that donald trump's hard-line, "fire and fury" stance towards pyongyang is working.

nick bryant, bbc news,ust the white laura: for more, i was joined a short time ago from boston by the former undersecretary of state for political affairs nicholas burns. the president says north korea is sincere in waing to talk and puts it down to sanctions. do you agree? nitolas: i think the presid is right that the sanctions had a lot to do with this. the u.s. sanctions, the united nations sanctions, and particularly, laura, what the chinese have done. they have done a lot more under prodding from president trump. he is right to say that sanctions play a big part. whether the north koreans e serious or not, we will see. i served in the clinton and george w. bush administrations, and the north koreans turned out to not be serious. this was the father and grandfather of kim jong-un.no laura: if h korea wants the u.s. to suspend the military drills with southe orea as a prr talks, is that going to drive a wedge between washington and seoul? nichol: one of the ambitions

of the north korean leadership is probably to drive a wedge htween us, to separate so korea, led by a president from the peace party, to separate south koreanfrom washington. we can't leththat happen. ere has to be unity among washington, tokyo, and seoul if we proceed teffective talks. one of the questions for korea is do we continue, do they continue with military exercises? it is not a bad idea to reaffirh policy of united states, that is that we will defend south korea and japan should they be attacked. we are obviouslythrepared to do . to remind the north koreans of that would be smart negotiating. laura: why would talks work this time come when as he said, and you are a veteran, they simply haven't before? what changed? nicholas: it could be that kim jong-un believes they ieve made suff progress through the nuclear tests, ballistic missile tests, and other related work

they have been doing to build a nuclear weapon that can reach the continentaunited states. if he feels that way, and if he is under pressure fr beijing, and i think beijing has come around to press the north koreans in a very tough way -- he may feel this is the best tactical move. sobut thh korean statement that initiated this said thate rth was ready for talks as long as the military security was going to the north koreans may mean they want the united states to leave the korean peninsula. they may ask for other concessions that the south koreans, the japanese, and the americans cannot give. the devil will be in the details, but this is a positive step forward. it makes sense for thed stes to want to have a negotiation, diplomatic contacts with this isolated regime, before we consider the use o force. laura: what is a nuclear armed north korea something we have to live with? nicholas: well, i don't think

that is where the trumps administrationarting, and they should not start there. they should continue to insist on what the united nations insists on, the denuclearizati. of north korbu kim is in a strong position here. pohe has nuclear w and is determined to keep them. at that you will see, laura -- i think you will see, laura, talks about talks, buttho denuclearize north korean arsenal will be a tall order indeed. laura: nicholas burns, thank you so much for joining us. nicholas: thank you. laura: u.k. counterterrorism officers are in charge of the investigation into the suspected poisoninof a former russian agent who once spied for britain . sergei skripal and his daughter suddenly fell i yesterday in salisbury. they remain in critical condition. military scientists ars testing samp the substance that may have caused their illness. tom symonds has the latest. tom: a father and a daughter apparently struck down in public on a sunday afternoon in salisbury.

the bbc revealed today that shen had isiting her fatherwh from russi it happened. they were left fighting for useir lives. >> the eyes werecompletely white,wide-open but just frothing at the mouth. the man, his arms stopped moving. still looking get straight. -- looking dead straight. tom: cctv images obtained by the bbc appearo show mr. skripal and his daughter walking together at 15:47 sunday afternoon. they were heading for a small pa in the center of salisbury. cara, which capture these pictures, is yards from where they were e und. police wlled at 4:15 when people reported the pair were h.unconscious on a park be last night an italian restaurant nearby was sealed by police, followed today by a local pub. did someone put something into their food or drink?th fopolice, this is a highly

sensitive and potentially hazardous investigation, not least for the officers involved the key questi course, is what was the substance that left a fathernd his daughter in such a terrible condition on the park bench, covered by the tent behind me? thtse will be toxicology rep prepared, but we understand several police officers were admitted to hospital. one has been kept in. symptoms includerehing difficulties and itchy eyes. experts at the research facility are now involved, testing for a wide range of substances. >> from things that are chemically toxic to things that are radiological. i think people will have an open mind. they will be looking at what is in the environment, what is on the clothing, on the skin of the the people, and what is in the blood and urine and any other

sample. tom: so for the polith force has leinvestigation, but that changed today in a significant development. the metropolitan police confirmed in unusual circumstances that the counterterrorism network wilbe leading the investigation, as it has the specialists, capability, and expertise to do so. etaryas the foreign se made clear in parliament this afternoon, this incident c for britain'sons relationship with russia. >> should evidence emerge of state responsibility, her ilmajesty's government respond appropriately and robustly. tom: sergei skripal was arrested in 2004, accused of spying for mi6, convicted, and in 2010, handed over to britain as part of a spy swap. sergei skripal's wife, elder brother, and son have died in cent years, the family believes in suspicious circumstances.

he has been living quietly here, vigilant and fearful of russian intelligence, relaves said, but under his own name. he would not have been hard to find. tom symonds, bbc new laura: 800 people have been killed in the syrian region of eastern ghouta in the past two weeks, according to a monitoring group. it is the last rebel stronghold and is being bombarded by government forces. russia's military, whichyr supports then government, has offered civilians a safe passage out. the rebel fighters have so far rejected this propos. our middle east editor jeremy bowen reports. it was another day in the life and death of eastern ghouta. the bbc has been following this doctor, a pedirician, in an underground hospital through the t days of attacks. this was filmed for the bbc. the syrian government will not allow us into the enclave. the doctor and her colleagues

were dealing with the results of airstrikes on a market. more than 20 dead and 90re inju ospital is stuffed with injured people, including women and children. the brain injuries include brain damage, fractured and amputated limbs. a child's arm was amputated. some children wore seriously unded. others were killed. jeremy: the doctor examined a boy who had been brought in, presum dead. she found a pulse. they went to work to get him to breathe. he was rushed into intensiveca re. but it was a false hope. a few hours later, he was dead.s in age, surrounded by casualties, the world shrinks to few essentials. the most important is survival.

living through this day, perhapt a chance tt another. on the battlefield, the syrian army, helped by russia, has been advancing. resistance seems to be collapsing. the trucks that took aid into the enclave were forced out by shelling, with 10 out of 46 still unloaded. u.n. aid workers said civilians were terrified, angry, and many wanted to get out, but couldn't. >>el they hat they are being blocked. there are snipers sitting at oichec exits. they are very unhappy with theiw groups inside. also, the narrative that is very strong among elders and leaderso is this place, we are not moving out from here. jeremy: a russian general saidgu his men woulantee the safety of civilians who wanted to get out. and he said fighters could leave

with their personal weapons and in unity. russian troops are very visible around the war zone. moscow h given the syrian army the firepower to break into rebel strongholds. on the front line around eastern ghouta, most of the troops were syrian, but the russians were there alongside them. russia is now the most important foreign power in this war.pr ident putin was given equal billing with president assad indisposition. the russians are preparing for the day after. it looks as if the endgame is approaching for the armed ouposition in eastern ghouta. elsewhere in thery, rebels still control territorugh not nearly as much as before. and fighting goes on. it is particularmo fierce at the nt near the turkish border. syria's war is changing, but it is not ending. jeremy bowen, bbc news, damascus.

"the new york times" is inreporting there's noe reason he is leaving. they are reporting that he had recent conversations with the president about replacing john staffas chief of he has become the latest

high-profile white house toappointennounce his departure. last week we were talking about hope hicks, white house communications directo now it is gary cohn, chief economic advisor. laura: the president said today that everyone wants to work in b the white hous is the amount of turmoil unprecedented? nick: statistically it is unprecedented. a lot of turnover in the reagan administration, but nothing like this. this morning he said "there is no chaos in my white house, ju great energy." he said in the press conference and hour ago that everyone wants a piece of the oval office. well, not gary cohn anymore. you must resigned last year afte -- she almost resigned last year after shows phil. gary cohn and he was very a friend -- is jewish and he was very offended that the president said they were very fine people in charlottesville. he wanted the federal reserve --

well, that went to somebody else. perhaps he feels his job is done now. another big-name departure from the white house. laura: he was planningn thursday t introduce the president to industry leaders in the u.s. who feel that t tariffs are a bad idea. did he just decided to give up the ghost? what does that say about the split in the republican party? have not announced the date of departure yet, so bring thosel still people in. but he will not have much influence because he is not does -- he does speak to the divide in the conservaltve movement -ugh gary ghouta is a democrat --gary cohn is a democrat. people steve bannon and who prefer free trade. this has been a free-trade party for years now. laura: nick bryant, thang you for join. the government in sri lanka has

aged to impose a 10-day state of emergency following attacks on muslim-owned businesses. andions between muslim buddhists have been growing over the last year. siificant drop in child marriages globally -- they believe in the lasts five year from 25% of underage marriages have been prevented. south asian countries have seen the biggest reduction. when make her l -- toymaker legd reportedp in profit, saying they made too many breaks. excess of stock had to sold off cheaply, causing the comedies first drop in sales in 13 years. first drop in's sales and 13 years. you are watching "bbc world news america." still to come on tonight's job showsow one man's in the human cost of america's immigration policy.

she was 17 when he began an began wh artist -- she an affair with artist pablo picasso and became his musical m now their story is the subject of a show in london. ♪ reporter: it is almost showing off. artists would only ev th show showingof a life's work -- this picasso exhibition is what he n one year, 1932. and of course we have had major picasso shows before in london. >> london honors for kosovo, -- icasso, the man ao painted th has gone on painting ever since. reporter: 50 years on, we don't question the style in the same way, but the more we know about his life provokes other in 1932,so picas married.

but the a paintin not of her. it is of olga. the concert was in his late 40's rwent there a f began -- but also was in his late 40's when there are fair began. did you find yourself unco >> most artists are complex and complicated human bein. i would say in particular they show their complication openly. certainly did is put all the contradictions out there. reporter: one thing remains unchanged, picasso's place in the art world. the london art market has been fizzing with sales. this exhibition is a snapshot of one year. when you add it all together, we are moving from a world of nsmillnto billions.

laura: the courts may have blocked president trump's youngne on the fate of undocumented immigrants known as -- for the 700,000 living in the u.s., their fate is uncertain. he was a border patrol agent before quitting. he has written a book called "the line becomes a rir: spatches from the border." >> the job of being a border patrol agent, there were certain aspects of it that appealed to me, that i enjoyed, beingtd rs.ng learni to read the landscape. but of course there was alwayswl this kge in the back of my mind that all of these things i was learning to do were to hunt down and to catch other people.

after leaving the job, what i carried with me the most and what i still carry with me today weren'u't the car chases or dr busts. what really sticks with me are the personal encounters and the conversations i had. when i read about deaths in the desert, i remember the face of the man whose bo i found in the desert. some of the discussion around the book is really about who gets to speak, who do we listen to, whose stories are being told, and by whom. i i think this important to listen to the voices of migrants, because they are the ones most affected by border policy.

migrants are the ones who are dehumanized at every single step in their journey. those are the voices that have more to tell us about border policy than y border agent like me, than any polimaker, than any politician. there is people who have been brought here, dreamers, who e now living in fear. i think we need to recognize eathat fear is something rand visceral, something we arehr creating tgh policy. there were all these parts of myself and my identity that i had to sort of gi over to this institution, and that is a question that is sort of at the nter of the book. comingrto terms with ipating in a violent system, enforcing policies that when i look at them now feel

inherently flawed and violent, and trying to come to te that.a: laow, before we go, we want to show you that it is possible to me your everyday heroes. a 2-year-old took over the internet recently when this photo was posted of her staring at the new portrait of michelle obama at the national portrait gallery here in washington, d.c. the picture was captureby a bystander also waiting to see the painting. if things couldn't even get more exciting for the toddler, today the two met in person and had a dance party. vimichelle obama posted tho on twitter and told parker, "keep on dreaming big for yourself and maybe one day iwi look up at a portrait of you."
