>> and now, "bbc world news >> this is a report from washington. i am katty kay. america and iran hold unprecedented top level meetings as president romani says nuclear disarmament is his country -- rouhani says nuclear disarmament is his country's number one priority. and his pictures capture the faces of a generation. tonight, we hear about a photojournalist known simply as l'americain. welcome to viewers on public

television and around the globe. the president of iran has told the united nations that nuclear disarmament is his first priority. this can shortly before the american secretary of state and american foreign minister -- and iranian foreign minister held a meeting, the highest level encounter in four decades. >> the meeting has just ended between the five permanent members of the un security council, germany, and the iranian delegation. foreign secretary william hague said the tone and spirit of the meeting were good. he said it was a big improvement. he described it as a good start. cathy ashton, representing the european union, called it a substantial meeting, and said it was a good atmosphere. we have not heard anything yet from the iranian delegation.

things are underway. here is our middle east editor. >> iran has a new president, hassan ronny -- hassan rouhani. he has come to try to change skeptical minds about iran. he has been calling for a deal on the nuclear program in the next three to six months, insisting iran wants to generate electricity, not make a bomb. he also returned to the un's general assembly to call for a nuclear-free middle east, which would mean israel giving up its nuclear weapons. he said israel should join the nonproliferation treaty, aimed at promoting disarmament. after four decades of international efforts to establish a nuclear weapons free zone in the middle east have are greatly failed, urgent practical steps toward the establishment of such a zone are necessary. israel, the only nonparty to the npt in this region, should

therefore join without delay. in tehran, the economy has been hit badly by international sanctions. a deal will relieve that pressure. rouhani and- mr. his trip had top billing, but he is not at the top of the pecking order. he is here in new york. he says he has full authority from the supreme leader to make a deal. william hague, britain's former his -- met with the american foreign minister. at the moment, is acting in defiance of the un security council and the atomic energy agency. it is acting in defiance of a nonproliferation treaty. before iran asks other countries

to do these things, of course we want to see transparency and concrete steps from iran. then, they can talk to the rest of the world. >> president rouhani has spent most of his career as an insider, close to the top of the islamic republic. him the ability to establish a better relationship with the west. what the iranians will not capitulate on their key interests. both sides to have to accept uncomfortable concessions if they are to make a deal. one of iran's missions at the amid so muchk international attention is to try to get long-term recognition where it's believed that it is a regional power with its own legitimate security interests. the president has managed to create a change for the better in the atmospherics. considering the outlook in the middle east is still so dismal and dangerous, that has to be a good start.

bbc news, new york. baroness cathy ashton, representing the european union, was in the meeting with the foreign minister, the americans, and other members of the security council. she said that confidence building measures were suggested to iran by the world powers who were present. it is now up to the iranian government to respond. what kind of confidence building measures specifically is the west looking for? and when will we know whether iran is prepared to give them? >> the west will be looking for iran to make some sort of commitment to reducing the percentage by which it in rich's uranium, so it will agree to enrich uranium at a much lower level. at a higher percentage, it can potentially be used for fuel for a nuclear bomb. they will also be looking for access to iran's nuclear

facilities for inspectors. they may be asking for access to some of the bunkers. sure, in return will be looking for the west to make some commitment about what sanctions it would ease if iran were to go along with these measures. it is the start of a process. >> a busy day at the united nations. iran dominating. we have also had, this evening, news that there does seem to be some sort of draft agreement on syria and chemical weapons as well. what can you tell us about that? >> or member a couple of weekends ago, the u.s. and agreedmeeting in geneva, to a framework by which syria would give up chemical weapons. an agreement codifying that has been put into a u.n. security council resolution. there'll be consultation tonight.

is to say they could try to facilitate talks in syria, in that civil war. a backer, an ally, of president assad. it is like so many pieces of a diplomatic jigsaw coming together. which he's process are we talking about? are we talking about iran, syria, or the israeli- palestinian question? a lot of action here at the united nation this week. the request of kenyan authorities, interpol has issued a red alert for a british woman. she is the widow of one of the four suicide bombers who attacked london in july 2005. wanted in connection with a bomb plot, but there are questions about whether she was also involved in the shopping

here, or because of an earlier kenyan plot she has been linked with. at the ruined westgate mall, forensic investigations are continuing. the teams are looking for bodies, and for the identities of the gunmen. reports that two of them have been identified cannot yet be confirmed. the foreign office has now revealed that five britons were killed, not six. no others are currently known to be missing. the funeral continues. this is for a radio for sender -- presenter and her unborn child. she had been hosting a children's cookery competition. she was shot and bled to death. her friend has a harrowing story of how she fooled the gunman as she laid still beside a child's dead body. >> i tried to put blood on myself.

scientists are going to extraordinary facts -- extraordinary lengths to get to the roots of global warming. clams live for a next on a shame lane -- for an astonishingly long time, which makes them crucial to science. the oldest again life back in the time of the tutors. henry vii was king. their shells can tell a story about the past climate, because the lines are like the rings in a tree, each marking one year growth. close up, thicker lines mean warmer conditions. >> these clams live for centuries. they are like miniature tape recorders living on the seabed. they record all the conditions around them in terms of food supply, seawater temperature. a show that over the last hundred years, sea water temperatures have been increasing. >> the claims provide a

temperature record over the past thousand years. warm in the middle ages, and even warmer now. tree rings can also crack past climate. ice cores offer information. the mostrmometers, reliable measure of all. world,e from the natural thermometers, and satellites, taken together, is what convinces scientists the world is getting warmer. it is widely agreed that mankind is causing at least some of this. the difficult question is how much amenity is responsible. greenhouse gases are adding to natural changes underway. -- somes it's scientists admit it is more complicated than first thought. >> we were confident that the knowledge we were generating -- what has happened in the last 10 or 15 years has shown much greater complexities. >> a mistake about glaciers in

the himalayas in a major u.n. report raise more questions. promisesclimate panel much greater care. are putting in place procedures that are much more robust. they are much more likely to be a strong safeguard. may i say this is a human undertaking? there isport will say more evidence than ever about our role in warming. but it may be more open about what we do not know. david shukman, bbc news, in north wales. >> still to come on tonight's program, an injured man is growing a new nose on his forehead. it is a medical breakthrough which is quite shocking. tens of thousands of people made homeless by an earthquake in

pakistan are still waiting for help, two days after it struck, and making matters worse, there are reports that a government helicopter surveying the damage has been fired upon. >> the devastation in some areas is total. possessions,, and buried. those who survived are desperate. with rescue teams struggling to reach remote areas, all people can do is dig with their hands. this man says the government has not given anything to earthquake victims. we did not even have a tent to give my family temporary shelter. we are getting by at night, but during the day, it is extremely hot. it is difficult for the children without any shelter. we have to find food, and now we have nowhere to cook. vast,fected area is

impoverished, and sparsely populated. without help, many people have limited or no access to food or water. those who have been able to get medical treatment have trouble to hospitals in cities like karachi, but they are also grieving. >> i was in my room, and my children were in another room. i do not know where my wife and children are, if they are alive or dead. i do not know where they are. was thewerful earthquake that it formed a new island off the coast, a mass of mud, stone, and gas, push from the seabed. it is just a little smaller than a football field. meanwhile, emergency workers are en route. that is little comfort for those who have been overwhelmed by this quake. bbc news.

>> this next story is nothing short of miraculous, despite seeming like it was ripped out of a sci-fi novel. doctors in china have carried out a medical first by growing a nose onto a patient's for head. the 22-year-old was badly injured in a road accident. have hiss waiting to strange transplant surgery. our correspondent reports on this groundbreaking treatment. >> it looks extraordinary. on his for head, an almost perfect nose. doctors nine months of painstaking work to construct. the patient, whose identity they want to protect, was injured in a car accident. chinese surgeons have had to build him a new nose, because his old one was too fragile to repair. the doctor says the surgery that is left to fit the nose is the easiest bit. this is how his team did it.

first, they expanded the skin in the four head, molding it into shape. then, they extracted cartilage from his ribs, and planted it into the space created. it has taken nine months to grow the nose. now, it is ready to be shifted into position. >> the chinese are very innovative. i think they are very good original thinkers, when it comes to these sorts of things. they also have a population that is very tolerant of developing, shall we say, surgical techniques. >> the technique itself is not new. 15 years ago, scientists in america created this replicate year from cow cartilage, and attested to a mouse to see if it would grow. what is unusual about the chinese team is, they have done it on their patient's four head. china is increasingly investing in cutting edge medicine, developing its own talent.

because this country wants to be seen as a world leader in science and research. china now has more than 2 million researchers, and it is spending a trillion pounds on innovation, seeking breakthroughs. these are the labs of the world's biggest gene sequencing company, bgi. has copied advances made elsewhere. growing the nose on his head means it can be moved into place with blood vessels and skin intact, ask amazing chances this surgery will be a success. chances theg surgery will be a success. >> you may not have ever heard ,f photographer john launois but you know the faces he has captured. his pictures appeared in some of the most influential magazines of the 1960's and 1970's. ericainnicknamed l'am

post" and "life magazine," and eventually "national geographic." my father knew how to charm people. he would make friends with ambassadors from russia and everywhere else. the soviet union, at that time, were for bidding western journalists from going in. he got in. that story was published in life magazine, i believe "time life." that started his rise into photojournalism, made him a top gun. the shoot was fun with the beatles. the concept was, the beatles were marking the establishment while becoming part of it, spoofing london's financial class. he needed deadpan expressions. thatld them, just think the sole purpose in life is to make money. theylooked really sad, and shot the shot. that is the cover.

book, my father not only documents the historical elements of everything he went through and covered in his photojournalistic life, but he also goes into the personal. i guess when you are really ambitious, sometimes you lose sight of those that are the closest to you. i consider him, in my mind, and impossible man with a beautiful heart. that pretty much describes him. he really did have a beautiful heart. but he could be impossible. i mean, he could drive you crazy. but he wanted to fight the good fight. that is for sure. lenoir.ork of john that brings the program to a close. you can carry on watching on our 24-hour channel, if you look at your listings. if you would like to reach me on bbc.er, i am at katty kay
